Polyphenols such as flavonoids have been shown to have beneficial health effects. In particular, polyphenols can provide beneficial effects by lowering the side effects of co-administered therapeutic agents, in some cases acting as Tissue transport protein modulators. While blood tissue barrier structures, such as the blood-brain barrier (BBB, blood pancreas barrier, blood kidney barrier, and blood-placenta barrier), function as n obstacle to a isolate the tissues from the systemic blood circulation, some pharmaceutical agents, such as anesthetic agents, cross the tissues selectively causing tissue specific toxicity or side-effects rather than a desired localized action. In addition, blood tissue barriers may be compromised by disease states and therapeutic treatments, causing barrier laxity and then permitting unwanted agents to cross the barrier and adversely affect tissue structures. Thus, there is a continued need in the field for compounds that will lower side effects of co-administered therapeutic agents, such as new tissue transport protein modulators, and for compositions and methods for improved delivery of polyphenols, flavonoids, and related compounds.

Reference will now be made in detail to particularly preferred embodiments of the invention. Examples of the preferred embodiments are illustrated in the following Examples section.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of skill in the art to which this invention belongs. All patents and publications referred to herein are incorporated by reference in their entirety.
The features of the invention are set forth with particularity in the appended claims. A better understanding of the features and advantages of the present invention will be obtained by reference to the following detailed description that sets forth illustrative embodiments, in which the principles of the invention are utilized, and the accompanying drawings of which:
This invention provides compositions and methods utilizing phosphorylated compounds and/or their metabolites which act in combination with a therapeutic agent to enhance the effectiveness and/or reduce the side effects of the therapeutic agent. The class of compounds of the invention is the class of phosphorylated polyphenol such as a phosphorylated pyrone analogs, for example phosphorylated flavonoids or phosphorylated polyhydroxylated aromatic compounds. Polyphenols, for example flavonoids can enhance the effectiveness and/or reduce the side effects of therapeutic agents, for example, immunosuppressants when administered in combination with such agents (see U.S. patent application Ser. Nos. 11/281,771, 11/281,984, 11/553,924, and 11/964,377; and PCT Patent Applications PCT/US2007/82691 and PCT/2007/88827). This invention provides phosphorylated analogs of these compounds which can have increased solubility and increased bioavailability. In addition, when co-administered with a therapeutic agent, the compounds of the present invention can increase the duration of the therapeutic effect of the agent, for example resulting in a longer half life of therapeutic effect. In some cases, one or more phosphates is cleaved from the phosphorylated polyphenol such as a phosphorylated pyrone analog in the body, for instance where the phosphorylated phenol acts as a pro-drug, and the cleavage of the phosphate releases a bioactive drug. In these cases, the released phosphate is a non-toxic substance that is well tolerated in the body at the levels generated.
In one aspect, the invention provides compositions and methods utilizing a phosphorylated polyphenol such as a phosphorylated pyrone analog as a side effect modulator. A “side effect modulator” as used herein includes agents that reduce or eliminate one or more side effects of one or more substances. In some embodiments, the invention provides compositions and methods utilizing a combination of a therapeutic agent and a phosphorylated polyphenol such as a phosphorylated pyrone analog that acts as an agent to reduce or eliminate a side effect of the therapeutic agent. Typically, the side effect modulator is a modulator of a blood tissue barrier (BTB) transport protein. The methods and compositions are useful in the treatment of an animal in need of treatment, where it is desired that one or more side effects of a substance, e.g., therapeutic agent be reduced or eliminated. In embodiments further utilizing a therapeutic agent, the methods and compositions are useful in the treatment of an animal in need of treatment, where it is desired that one or more side effects of the therapeutic agent be reduced or eliminated while one or more of the therapeutic effects (e.g., peripheral effects) of the agent are retained or enhanced.
In some embodiments of the invention, the therapeutic agent is an immunosuppressive agent, such as a calcineurin inhibitor or a non-calcineurin inhibitor. In some embodiments of the invention, the therapeutic agent is a non-immunosuppressive agent. The phosphorylated polyphenol such as a phosphorylated pyrone analog and/or its metabolite, acting as an agent causing a decrease in the side effects of the therapeutic agent, e.g., a modulator of a BTB transport protein, may be an activator or an inhibitor of the protein. The modulatory effect may be dose-dependent, e.g., some modulators act as activators in one dosage range and inhibitors in another. In some embodiments, a modulator of a BTB transport protein is used in a dosage wherein it acts primarily as an activator.
In some embodiments the therapeutic agent is not an antipsychotic agent. In some embodiments, the therapeutic agent is not chlorpromazine.
Typically, the use of a phosphorylated polyphenol such as a phosphorylated pyrone analog and/or its metabolite as the BTB transport protein modulator, e.g., activator, results in a decrease in one or more side effects of the therapeutic agent. The therapeutic effect(s) of the agent may be decreased, remain the same, or increase; however, in preferred embodiments, if the therapeutic effect is decreased, it is not decreased to the same degree as the side effects. It will be appreciated that a given therapeutic agent may have more than one therapeutic effect and/or one or more side effects, and it is possible that the therapeutic ratio (in this case, the ratio of change in desired effect to change in undesired effect) may vary depending on which effect is measured. However, typically at least one therapeutic effect of the therapeutic agent is decreased to a lesser degree than at least one side effect of the therapeutic agent.
In addition, in some embodiments, one or more therapeutic effects of the agent is enhanced by use in combination with phosphorylated polyphenol such as a phosphorylated pyrone analog and/or its metabolite acting as a BTB transport protein modulator, while one or more side effects of the therapeutic agent is reduced or substantially eliminated. For example, in some embodiments, the immunosuppressive effect of an immunosuppressive agent is enhanced while one or more side effects of the agent is reduced or substantially eliminated.
Without being bound by theory, and as an example only of a possible mechanism, it is thought that the methods and compositions of the invention operate by reducing or eliminating the concentration of the therapeutic agent from a compartment or compartments in which it causes a side effect, while retaining or even increasing the effective concentration of the agent in the compartment or compartments where it exerts its therapeutic effect.
It will be appreciated that the therapeutic and/or side effects of an therapeutic agent may be mediated in part or in whole by one or more metabolites of the therapeutic agent, and that a BTB transport protein modulator that reduces or eliminates the side effect compartment concentration of the therapeutic agent and/or of one or active metabolites of the therapeutic agent that produce side effects, while retaining or enhancing a therapeutic compartment concentration of the therapeutic agent and/or one or more metabolites producing a therapeutic effect, is also encompassed by the methods and compositions of the invention. In addition, a phosphorylated polyphenol such as a phosphorylated pyrone analog may be converted in vivo to metabolites that have differing activities in the modulation of one or more BTB transport modulators, and these metabolites are also encompassed by the compositions and methods of the invention.
Hence, in some embodiments the invention provides compositions that include a therapeutic agent and a phosphorylated polyphenol such as a phosphorylated pyrone analog, where the therapeutic agent is present in an amount sufficient to exert a therapeutic effect and the phosphorylated polyphenol is present in an amount sufficient to decrease side effect of the therapeutic agent when compared to the side effect without the phosphorylated polyphenol, when the composition is administered to an animal. The decrease in the side effect can be measurable. The phosphorylated polyphenol and/or its metabolite is a BTB transport protein activator in some embodiments. In some embodiments the phosphorylated polyphenol is a modulator of ATP binding cassette (ABC) transport proteins. In some embodiments the phosphorylated polyphenol is a modulator of P-glycoprotein (P-gP).
In some embodiments, compositions of the invention include one or more than one therapeutic agent as well as one or more than one phosphorylated polyphenol. One or more of the therapeutic agents may have one or more side effects which are desired to be decreased.
Compositions of the invention may be prepared in any suitable form for administration to an animal. In some embodiments, the invention provides pharmaceutical compositions.
In some embodiments, the invention provides compositions suitable for oral administration. In some embodiments, compositions are suitable for transdermal administration. In some embodiments, compositions are suitable for injection by any standard route of injection, e.g., intravenous, subcutaneous, intramuscular, or intraperitoneal. Compositions suitable for other routes of administration are also encompassed by the invention, as described herein.
The phosphorylated polyphenols of use in the invention include any phosphorylated polyphenol that results in the desired decrease in side effect of a therapeutic agent and/or the increased therapeutic effect of the therapeutic agent, for example, that is a suitable BTB transport protein modulator. In some embodiments, the phosphorylated polyphenol is one or more phosphorylated flavonoids or phosphorylated polyhydroxylated aromatic compounds. In some embodiments, the BTB transport protein modulator is a phosphorylated quercetin. In some embodiments, the BTB transport protein modulator is a phosphorylated fisetin. In some embodiments, the BTB transport protein modulator is a phosphorylated 5,7-dideoxyquercetin. In some embodiments, the BTB transport protein modulator is a quercetin-3′-O-phosphate.
In some embodiments the invention provides methods of treatment. In certain embodiments, the invention provides a method of treating a condition by administering to an animal suffering from the condition an effective amount of a therapeutic agent and an amount of a phosphorylated polyphenol, e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin, sufficient to reduce or eliminate a side effect of the therapeutic agent. In some embodiments the phosphorylated polyphenol and/or its metabolite is a BTB transport protein activator. In some embodiments, the therapeutic agent is an immunosuppressive agent, e.g., an calcineurin inhibitor or a non-calcineurin inhibitor. In certain embodiments the invention provides methods for the prevention of solid organ graft rejection, e.g., host versus graft disease, or graft versus host disease by administration of an immunosuppressive agent, e.g., an calcineurin inhibitor.
In some embodiments the invention provides methods of decreasing a side effect of an agent in an animal, e.g. a human, that has received an amount of the agent sufficient to produce a side effect by administering to the animal, e.g., human, an amount of a phosphorylated polyphenol sufficient to reduce or eliminate the side effect. In certain embodiments, the agent is an anesthetic, e.g., a general anesthetic. In certain embodiments, the agent is a therapeutic agent or drug of abuse that has been administered in excess, e.g., in an overdose.
The phosphorylated polyphenols and phosphorylated pyrone analogs of the invention can be derived from the class of compounds referred to as polyphenols, a group of chemical substances found characterized by the presence of more than one phenol group per molecule. Some polyphenols are naturally occurring in plants. Polyphenols can generally be subdivided into tannins, and phenylpropanoids such as lignins, and flavonoids. Suitable phosphorylated polyphenols include phosphorylated catechins. Catechins have been isolated from green tea, and include (−) epicatechin. See Wang, E, et al., Biochem. Biophys. Res. Comm. 297:412-418 (2002); Zhou, S., et al., Drug Metabol. Rev. 36:57-104 (2004), both of which are herein incorporated by reference in their entirety. Other suitable phosphorylated polyphenols for use herein include phosphorylated flavonols, including, but not limited to, phosphorylated kaempferol, phosphorylated quercetin, phosphorylated fisetin, phosphorylated 5,7-dideoxyquercetin, and phosphorylated galangin.
The chemistry for conversion of —OH groups to phosphate groups is well known in the art and can be accomplished for example by reaction with phosphoric acid (see e.g. Organic Letters, 7(10), (2005), 1999-2002). In other embodiments, phosphorylation will involve the conversion of an H group or other group bound directly to a carbon to a phosphate group such as —OPO3XY or —OPO3Z group where X and Y can be hydrogen, an alkyl (such as methyl or ethyl), a carbohydrate, or a cation, and where Z is a multivalent cation. The phosphate group can also be referred to as a phosphonoxy group. Some phosphorylated flavonoids useful in the present invention are described in WO 93/09786, JP 01308476, and JP 01153695. In some cases, the phosphorylated compound will have a cyclic phosphate structure, such as a 5 membered ring that is formed when the phosphorous of the phosphate bridges two hydroxyl groups on adjacent carbons.
In some cases the phosphorylated polyphenols of the invention comprise polyphosphate derivatives. Polyphosphate derivatives are those in which more than one phosphate is connected in a linear chain. Suitable polyphosphate derivatives include, for example, diphosphates (pyrophosphates), and triphosphates.
As used herein and in the appended claims, the singular forms “a,” “and,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a compound” includes a plurality of such compounds, and reference to “the cell” includes reference to one or more cells (or to a plurality of cells) and equivalents thereof known to those skilled in the art, and so forth. When ranges are used herein for physical properties, such as molecular weight, or chemical properties, such as chemical formulae, all combinations and subcombinations of ranges and specific embodiments therein are intended to be included. The term “about” when referring to a number or a numerical range means that the number or numerical range referred to is an approximation within experimental variability (or within statistical experimental error), and thus the number or numerical range may vary between 1% and 15% of the stated number or numerical range. The term “comprising” (and related terms such as “comprise” or “comprises” or “having” or “including”) is not intended to exclude that in other certain embodiments, for example, an embodiment of any composition of matter, composition, method, or process, or the like, described herein, may “consist of” or “consist essentially of” the described features.
“Acyl” refers to a —(C═O)— radical which is attached to two other moieties through the carbon atom.

Stereoisomers may be obtained, if desired, by methods known in the art as, for example, the separation of stereoisomers by chiral chromatographic columns.
In some embodiments, the invention utilizes a phosphorylated quercetin aglycone. In some embodiments, a combination of phosphorylated aglycones and phosphorylated carbohydrate-derivatized quercetins is used. It will be appreciated that the various forms of quercetin may have different properties useful in the compositions and methods of the invention, and that the route of administration can determine the choice of forms, or combinations of forms, used in the composition or method. Choice of a single form, or of combinations, is a matter of routine experimentation.
Thus, in some embodiments the invention features a composition or method utilizing phosphorylated quercetin, phosphorylated fisetin, phosphorylated 5,7-dideoxyquercetin and or its metabolites to reduce or eliminate one or more side or fetal effects of a substance, such as a therapeutic agent, e.g., an immunosuppressive.
In some embodiments, the phosphorylated flavonoid, e.g. phosphorylated quercetin, phosphorylated fisetin, phosphorylated 5,7-dideoxyquercetin is provided in a form for oral consumption. Oral bioavailability of phosphorylated quercetin O-saccharides may be superior to that of phosphorylated quercetin aglycones, or the saccharide derivative may have other properties useful in the invention. The bioavailability of the various components is dependent on 1) the site of carbohydrate moiety or moieties and ii) the pendant sugar unit. In addition it is believed that specific carriers can be responsible for the absorption of various quercetin glycosides, as well as specific intestinal betaglucosidases. After distribution in the body, the major metabolite, quercetin glucuronide (e.g., quercetin 3-O-glucoronide), may be found. Oral bioavailability can be sensitive to the presence of food factors.
In compositions for oral delivery of phosphorylated quercetin, carbohydrate-derivatized forms (also referred to herein as “phosphorylated quercetin saccharides”) are used in some embodiments; various combinations of carbohydrate-derivatized forms and/or aglycone may be used in some embodiments. In some embodiments, phosphorylated quercetin-3-O-glycoside is used in an oral preparation of quercetin; in some embodiments, a pharmaceutically acceptable excipient is included in the composition. In some embodiments, phosphorylated quercetin 3-O-glucorhamnoside is used in an oral preparation of quercetin; in some embodiments, a pharmaceutically acceptable excipient is included in the composition. In some embodiments, a combination of phosphorylated quercetin-3-O-glycoside and phosphorylated quercetin 3-O-glucorhamnoside is used in an oral preparation of quercetin; in some embodiments, a pharmaceutically acceptable excipient is included in the composition. Other carbohydrate-derivatized forms of quercetin, or other forms of phosphorylated quercetin which are derivatives as described above, can also be used, based on their oral bioavailability, their metabolism, their incidence of gastrointestinal or other side effects, and other factors known in the art. Determining the bioavailability of phosphorylated quercetin in the form of derivatives including aglycones and glycosides is a matter of routine experimentation. See, e.g., Graefe et al., J. Clin. Pharmacol. (2001) 451:492-499; Arts et al. (2004) Brit. J. Nutr. 91:841-847; Moon et al. (2001) Free Rad. Biol. Med. 30:1274-1285; Hollman et al. (1995) Am. J. Clin. Nutr. 62:1276-1282; Jenaelle et al. (2005) Nutr. J. 4:1, and Cermak et al. (2003) J. Nutr. 133: 2802-2807, all of which are incorporated by reference herein in their entirety.
“Carbohydrate” as used herein, includes, but not limited to, monosaccharides, disaccharides, oligosaccharides, or polysaccharides. Monosaccharide for example includes, but not limited to, allose, altrose, mannose, gulose, Idose, glucose, galactose, talose, and fructose. Disaccharides for example includes, but not limited to, glucorhamnose, trehalose, sucrose, lactose, maltose, galactosucrose, N-acetyllactosamine, cellobiose, gentiobiose, isomaltose, melibiose, primeverose, hesperodinose, and rutinose. Oligosaccharides for example includes, but not limited to, raffinose, nystose, panose, cellotriose, maltotriose, maltotetraose, xylobiose, galactotetraose, isopanose, cyclodextrin (α-CD) or cyclomaltohexaose, β-cyclodextrin (β-CD) or cyclomaltoheptaose and γ-cyclodextrin (γ-CD) or cyclomaltooctaose. Polysaccharide for example includes, but not limited to, xylan, mannan, galactan, glucan, arabinan, pustulan, gellan, guaran, xanthan, and hyaluronan. Some examples include, but not limited to, starch, glycogen, cellulose, insulin, chitin, amylose and amylopectin. For further description of carbohydrate moieties, see U.S. Patent Publication No. 2006/0111308, in particular paragraphs [122] and PCT Publication No. WO0655672, in particular paragraphs [90]-[108].
In some of these embodiments, a pharmaceutically acceptable excipient is also included. In some embodiments, the phosphorylated polyphenols can be formulated with cyclodextrins. Cyclodextrins and their derivatives can be used in liquid formulations to enhance the aqueous solubility of hydrophobic compounds. Cyclodextrins are cyclic carbohydrates derived from starch. The unmodified cyclodextrins differ by the number of glucopyranose units joined together in the cylindrical structure. The parent cyclodextrins typically contain 6, 7, or 8 glucopyranose units and are referred to as alpha-, beta-, and gamma-cyclodextrin respectively. Each cyclodextrin subunit has secondary hydroxyl groups at the 2 and 3-positions and a primary hydroxyl group at the 6-position. The cyclodextrins may be pictured as hollow truncated cones with hydrophilic exterior surfaces and hydrophobic interior cavities. In aqueous solutions, these hydrophobic cavities can incorporate hydrophobic organic compounds, which can fit all, or part of their structure into these cavities. This process, sometimes referred to as inclusion complexation, may result in increased apparent aqueous solubility and stability for the complexed drug. The complex is stabilized by hydrophobic interactions and does not generally involve the formation of any covalent bonds.
Cyclodextrins can be derivatized to improve their properties. Cyclodextrin derivatives that are particularly useful for pharmaceutical applications include the hydroxypropyl derivatives of alpha-, beta- and gamma-cyclodextrin, sulfoalkylether cyclodextrins such as sulfobutylether beta-cyclodextrin, alkylated cyclodextrins such as the randomly methylated beta.-cyclodextrin, and various branched cyclodextrins such as glucosyl- and maltosyl-beta.-cyclodextrin. Chemical modification of the parent cyclodextrins (usually at the hydroxyl moieties) has resulted in derivatives with sometimes improved safety while retaining or improving the complexation ability of the cyclodextrin. The chemical modifications, such as sulfoalkyl ether and hydroxypropyl, can result in rendering the cyclodextrins amorphous rather than crystalline, leading to improved solubility.
In some embodiments, the phosphorylated polyphenols for example phosphorylated pyrone analog such as a phosphorylated flavonoid, e.g. phosphorylated quercetin are formulated with sulfoalkyl ether derivatives. The sulfoalkyl ether —CDs are a class of negatively charged cyclodextrins, which vary in the nature of the alkyl spacer, the salt form, the degree of substitution and the starting parent cyclodextrin. A useful form of cyclodextrin is sulfobutylether-7-β-cyclodextrin, which is available under the trade name Captisol™ form CyDex, Inc. which has an average of about 7 substituents per cyclodextrin molecule. The anionic sulfobutyl ether substituents improves the aqueous solubility of the parent cyclodextrin. Reversible, non-covalent, complexation of flavonoids with the sulfobutylether-7-β-cyclodextrin. cyclodextrin can provide for increased solubility and stability of phosphorylated polyphenols in aqueous solutions.
In some embodiments, the invention provides methods and compositions that modulate a blood tissue barrier (BTB) transport protein. BTB transport proteins play a role in the maintenance of barrier to foreign molecules and/or removal of substances from spaces (e.g. cells). A BTB barrier may be any structure that is capable of modulating the concentration of a substance (e.g., therapeutic agent) in a physiological compartment. The barrier can be a boundary between blood and a physiological compartment such as a cell, an organ, or a tissue. The barrier can be a cell membrane or a layer of cells. One example of such a barrier is the blood kidney barrier. In some embodiments, the phosphorylated polyphenol and/or its metabolite acts as a modulator of a BTB transport protein. In some embodiments, the phosphorylated polyphenol and/or its metabolite acts as a modulator of a BTB transport protein that is an ABC transport protein (see below). In some embodiments, the phosphorylated polyphenol and/or its metabolite acts as a BTB transport protein activator. In some embodiments, the phosphorylated polyphenol and/or its metabolite is a modulator of P-gP, e.g., an activator of P-gP (see below).
A. Blood-Tissue Barrier Transporters
Without being limited by theory, it is thought that the compositions and methods of the invention operate by modulating the transport of molecules across blood-tissue barriers, thus altering their concentration in one or more physiological compartments. There are many different types of BTB transporters, and it will be understood that compositions and methods of the invention may involve one or more than one BTB transporter. Other mechanisms may also be involved.
In some embodiments, the invention provides methods and compositions that modulate ATP Binding Cassette (ABC) transport proteins. ABC transport proteins is a superfamily of membrane transporters with similar structural features. These transport proteins are widely distributed in prokaryotic and eukaryotic cells. They are critical in the maintenance of barrier to foreign molecules and removal of waste from privileged spaces, and may be overexpressed in certain glial tumors conferring drug resistance to cytotoxic drugs. 48 members of the superfamily are described. There are 7 major subfamilies, which include ABC A-G. Subfamilies C, B, and G play a role in transport activity at, e.g., the blood brain barrier and blood-CSF barrier. ABC A substrates include lipids and cholesterol; ABC B transporters include P-glycoprotein (P-gP) and other multi drug resistance proteins (MRPs); ABC C contains MRP proteins; ABC E are expressed in ovary, testis and spleen; and ABC G contains breast cancer resistance protein (BCRP).
Other examples of blood-tissue barrier transporters that can be modulated by methods and compositions of the invention include organic anion transport systems (OAT), and the GABA transporters GAT-1 and GAT2/BGT-1. Substrate compounds for OATs include enkephalins and deltorphin II, anionic compounds, indomethacin, salicylic acid and cimetidine. OATs are inhibited by baclofen, tagamet, indomethacin, etc. and transport HVA (dopamine metabolite) and metabolites of norepinephrine, epinephrine, 5-HT3, and histamine.
GABA transporters are Na and Cl dependent, and are specific for GABA, taurine, β alanine, betaine, and nipecotic acid. GAT2 transporters are localized to abluminal and luminal surfaces of capillary endothelial cells. GAT-1 is localized to the outside of neurons and glia. GABA-transporter substrates include lorazepam, midazolam, diazepam, clonazepam and baclofen. Probenecid inhibits luminal membrane GABA transporters from capillary endothelial cells. GAT-1 is inhibited by Tiagabine.
P-glycoprotein
In some embodiments, the invention provides methods and compositions that modulate P-gP, e.g., that activate P-gP. P-gP, also known as ABCB1, forms a protective barrier to pump away by excreting compounds into, e.g., bile, urine, and intestinal lumen. Three isoforms have been identified in rodents (mdr1a, mdr1b, mdr2) and two in humans (MDR1 and MDR2). It is expressed in epithelium of the brain choroid plexus (which forms the blood cerebrospinal fluid barrier), as well as on the luminal surface of blood capillaries of the brain (blood-brain barrier) and other tissues known to have blood-tissue barriers, such as the placenta, the ovaries, and the testes.
In the brain, P-gP is expressed in multiple cell types within brain parenchyma including astrocytes and microglia and in luminal plasma membrane of capillary endothelium where it acts as a barrier to entry and efflux pump activity. P-gP transports a wide range of substrates out of cerebral endothelial cells into vascular lumen. P-gP is also expressed in the apical membrane of the choroid plexus and may transport substances into CSF.
P-gP substrates include molecules that tend to be lipophilic, planar molecules or uncharged or positively charged molecules. Non-limiting examples include organic cations, weak organic bases, organic anions and other uncharged compounds, including polypeptides and peptide derivatives, aldosterone, anthracyclines, colchicine, dexamethasone, digoxin, diltiazem, HIV protease inhibitors, loperamide, MTX, tacrolimus, morphine, ondansetron, phenyloin and β-blockers. Inhibitors of P-gP include quinidine, verapamil, rifampin, PSC 833 (see Schinkel, J. Clin Invest., 1996, herein incorporated by reference in its entirety) cyclosporine A, carbamazepine, and amitryptiline.
Multi-drug resistance protein (MRP) substrates include acetaminophen glucuronide, protease inhibitors, methotrexate and ampicillin. Inhibitors of MRP include buthionine sulphoximine, an inhibitor of glutathione biosynthesis.
Breast Cancer Resistant Protein (BCRP)
BCRP, an ATP-driven transporter, is highly expressed, e.g., in the placenta. Allikmets R., et al., Cancer Res. 58:5337-5339 (1998), herein incorporated by reference. BCRP is responsible for rendering tumor cells resistant to chemotherapeutic agents, such as topotecan, mitoxantrone, doxorubicin and daunorubicin. Allen J D, et al., Cancer Res. 59:4237-4241 (1999). BCRP has also been shown to restrict the passage of topotecan and mitoxantrone to the fetus in mice. Jonker J W et al., J. Natl. Cancer Inst. 92:1651-1656 (2000), herein incorporated by reference.
Monoamine Transporters
Monoamine transporters include serotonin transporter (SERT), norepinephrine transporter (NET) and the extraneuronal monoamine transporter (OCT3). Ramamoorthy S, et al., Placenta 14:449-461 (1993); Ramamoorthy S., et al., Biochem. 32:1346-1353 (1993); Kekuda R., et al., J. Biol. Chem. 273:15971-15979 (1998), all herein incorporated by reference.
Organic Cation Transporters
Organic Cation Transporters also exist, e.g., in the placenta. Placental Na+-driven organic cation transporter 2 (OCTN2) has been identified and localized to the basal membrane of the synctiotrophoblast. Wu X et al., J. Pharmacol. Exp. Ther. 290:1482-1492 (1999), herein incorporated by reference. Placental OCTN2 transports carnitine across the placenta in the direction of the material-to-fetal transfer. Ohashi R., et al., J. Pharmacol. Exp. Ther. 291:778-784 (1999), herein incorporated by reference. Studies have identified methamphetamine, quinidine, verapamil, pyrilamine, desipramine, dimethylamiloride, cimetidine, and procainimide as drug substrates for OCTN2. Wu X, et al., Biochem. Biophys. Res. Commun. 246:589-595 (1998); Wu X, et al., Biochim. Biophys. Acta 1466:315-327 (2000), herein incorporated by reference.
Monocarboxylate Transporters and the Dicarboxylate Transporters
Another type of BTB transporters include monocarboxylate (MCT) and dicarboxylate (NaDC3 transporters. Both MCT (e.g. lactate transport) and NaDC3 (e.g. succinate transport), which utilize electrochemical gradients for transport, are localized to the brush border membrane of the placenta, with MCT being expressed in the basal membrane to a lesser extent. Price N T, et al., Biochem. J. 329:321-328 (1998); Ganaphthy V, et al., Biochem J. 249:179-184 (1988); Balkovetz D F, et al., 263:13823-13830 (1988), all incorporated by reference herein. Valproic acid, a teratogenic substance, may be a substrate for MCT transfer, and compete with lactate for transport across the placental barrier. Nakamura H. et al., Pharm. Res. 19:154-161 (2002), herein incorporated by reference.
Further information on exemplary transporters that can be modulated in embodiments of the methods and compositions of the invention are provided in Tables 1 and 2, below.
B. Blood Brain Barrier
Blood-tissue barriers may be illustrated by the blood brain barrier (BBB) and its mechanisms for controlling access to the CNS; however, it will be understood that the mechanisms described herein for the BBB are applicable, where appropriate, to other BTBs (especially in terms of transport proteins), and that the BBB is used as an illustrative example.
The access to the brain is controlled by at least two barriers, i.e., blood brain barrier (BBB) and blood-cerebrospinal fluid (CSF) barrier. As used herein, the term “blood brain-barrier” can encompass the blood-brain and blood-CSF barriers, unless otherwise indicated. The methods and compositions described herein are suitable for modulating the access of drugs and other substances into the brain. In some embodiments, the methods and compositions involve the modification of the blood brain barrier and/or blood-CSF barrier to prevent or reduce the entry of drugs into the central nervous system (CNS), e.g., by promoting efflux of the drugs from the CNS. In some embodiments, the compositions and methods of the invention utilize a modulator of a blood brain-barrier transport protein. In some embodiments, the compositions and methods of the invention utilize an activator of a blood brain-barrier transport protein.
The blood brain barrier regulates the transfer of substances between circulating blood and brain by facilitated transport and/or facilitated efflux. The interface on both luminal and abluminal surfaces contain physical and metabolic transporter components.
The exchange of substances between circulating blood and brain can be determined by evaluating octanol/H20 partition coefficient, facilitated transport, and/or facilitated efflux. The methods of measuring blood brain barrier integrity can be used to identify suitable central nervous system modulators for use in the methods and compositions described herein.
Various transporters exist to regulate rate of brain permeation for compounds with varying lipophilicity. Generally, hydrophilic nutrients, such as glucose and amino acids, are allowed entry into the physiological compartments of the methods and compositions disclosed herein. Conversely, compounds with low lipophilicity are pumped away from the physiological compartments by, for example, xenobiotic efflux transporters. These transporters are preferably modulated by the methods and compositions described herein to prevent entry of compounds and drugs into the central nervous system.
The blood CSF barrier is formed by the tight junctions of the epithelium of the choroid plexus and arachnoid membrane surrounding the brain and spinal cord. It is involved in micronutrient extraction, clearance of metabolic waste, and transport of drugs.
Mechanisms and routes of compounds into and out of brain include paracellular aqueous pathway for water soluble agents, transcellular lipophilic pathway for lipid soluble agents, transport proteins for glucose, amino acids, purines, etc., specific receptor mediated endocytosis for insulin, transferrin, etc., adsorptive endocytosis for albumin, other plasma proteins, etc., and transporters (e.g., blood-brain barrier transport proteins) such as P-glycoprotein (P-gP), multi-drug resistance proteins (MRP), organic anion transporter (OAT) efflux pumps, gamma-aminobutyric acid (GABA) transporters and other transporters that modulate transport of drugs and other xenobiotics. Methods and compositions of the invention may involve modulation of one or more of these transporters. Preferably, the central nervous system modulators affect one or more of these mechanisms and routes to extrude drugs from the central nervous system.
The methods and compositions described herein also modulate other barriers, such as neuronal transport barriers, as well as other barriers.
Active Transporters
Another embodiment of the methods and compositions disclosed herein is use of a phosphorylated polyphenol, e.g. a phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin and/or its metabolite in manipulating active transport of drugs, chemicals and other substances across the placental barrier. Active transport across the placental barrier, as opposed to facilitated diffusion or passive transport, requires energy, usually in the form of adenosine triphosphate (ATP) or through energy stored in the transmembrane electrochemical gradient provided by Na+, Cl− or H+. Because of the input of energy, active transport systems may work against a concentration gradient, however, saturation of the transporters can occur.
Extensive studies have been conducted regarding placental transport systems of nutrients, such as amino acids, vitamins and glucose. See Hahn T, et al., Early Pregnancy 2:168-182 (1996); Moe A J, Am. J. Physiol. 268:C1321-1331 (1995); Bissonnette J M, Mead Johnson Symp. Perinat. Dev. Med., 18:21-23 (1981), all incorporated herein by reference. Active transport of drugs occurs through the same transport systems, most likely due to structurally similarities between the transported drugs and endogenous substrates. Syme et al. (2004).
Active drug transporters are located either in the maternal-facing brush border (apical) membrane or the fetal-facing basolateral (basal) membrane where they pump drugs into or out of the synctiotrophoblast. Table 2 summarizes the active transporters that have been identified in the placenta.
In one aspect, the invention provides compositions and methods to reduce or eliminate one or more side effects of a substance. The substance may be produced in the subject in a normal or abnormal condition (e.g., beta amyloid in Alzheimer's disease). The substance may be an agent that is introduced into an animal, e.g., a therapeutic agent (e.g., an immunosuppressive to decrease rejection in organ transplant). It will be appreciated that some therapeutic agents are also agents produced naturally in an animal, and the two groups are not mutually exclusive. In some embodiments, the compositions and methods retain or enhance a desired effect of the substance, e.g., a peripheral effect. The methods and compositions of the invention apply to any therapeutic agent for which it is desired to reduce one or more side effects of the agent and/or enhance one or more of the therapeutic effects of the agent. In some embodiments, the compositions and methods of the invention utilize an immunomodulator such as an immunosuppressive agent. In some embodiments, the immunosuppressive agent is an calcineurin inhibitor. In some embodiments, the immunosuppressive is a non-calcineurin inhibitor. It will be appreciated that some agents that have primarily an immunosuppressive effect also have other therapeutic effects, while some agents that have primarily a non-immunosuppressive therapeutic effect also provide some degree of immunosuppression. The invention encompasses these therapeutic agents as well.
Hence, in some embodiments, the methods and compositions of the present invention can be used to modulate the effects of one or more of a variety of therapeutic agents. In some embodiments, the dosage of the therapeutic agent will be modulated according to the effect of the side effect modulator. For instance, less therapeutic agent may be needed to reach optimal effect when co-administered with the side effect modulator. In other embodiments co-administering the side effect modulator with a therapeutic agent will allow for chronically administering the drug without drug escalation and/or without dependence on the drug. In another embodiment co-administering the side effect modulator will allow for the elimination of a therapeutic agent from a physiological compartment, i.e. wash out drug in an overdose situation or to wake up a patient faster after anesthesia. In some embodiments, the physiological compartment is a central nervous system. In some embodiments, the physiological compartment is a fetal compartment.
The “side effect” of the therapeutic agent for which modulation is sought may be any effect associated with the agent that occurs in addition to the therapeutic effect. In some embodiments, the compositions and methods of the invention are used to decrease undesirable side effects and or increase desirable side effects or therapeutic effects of a therapeutic agent. Side effects are often specific to the agent, and are well-known in the art for various therapeutic agents. The effect may be acute or chronic. The effect may be biochemical, cellular, at the tissue level, at the organ level, at the multi-organ level, or at the level of the entire organism. The effect may manifest in one or more objective or subjective manners, any of which may be used to measure the effect.
An exemplary side effect, associated with many types of therapeutic agents, e.g., calcineurin inhibitor, is a central nervous system (CNS) effect. The term “central nervous system (CNS) effect,” as used herein, encompasses any effect of a substance in the CNS. For some substances that may be normally or abnormally produced in the CNS, such as amyloid beta, the effect may be a pathological effect. In some embodiments, the side effect of a substance can be drowsiness, impaired concentration, sexual dysfunction, sleep disturbances, habituation, dependence, alteration of mood, respiratory depression, nausea, vomiting, lowered appetite, lassitude, lowered energy, dizziness, memory impairment, neuronal dysfunction, neuronal death, visual disturbances, impaired mentation, tolerance, addiction, hallucinations, lethargy, myoclonic jerking, or endocrinopathies, or combinations thereof.
Other exemplary side effects include hypogonadism (e.g., lowered testosterone) and hyperglycemia associated with some therapeutic agents, e.g., immunosuppressants agents such as calcineurin inhibitors, e.g., tacrolimus. In some embodiments, the side effect is a renal and/or urogenital side effect, for example, nephrotoxicity, renal function impairment, creatinine increase, urinary tract infection, oliguria, cystitis haemorrhagic, hemolytic-uremic syndrome or micturition disorder, as well as other effects mention herein, or combinations thereof. In some embodiments, side effect is a hepatic, pancreatic and/or gastrointestinal side effect such as necrosis, hepatotoxicity, liver fatty, venooclusive liver disease, diarrhea, nausea, constipation, vomiting, dyspepsia, anorexia, or LFT abnormal, as well as other effects mention herein, or combinations thereof. Other side effects are described, for example in U.S. published Patent Applications US2006/0111308 and US2008/0161248; and PCT published Patent Applications WO/06055672 and WO/08083160, all of which are incorporated by reference herein in their entirety.
A “therapeutic effect,” as that term is used herein, encompasses a therapeutic benefit and/or a prophylactic benefit. By therapeutic benefit is meant eradication or amelioration of the underlying disorder being treated. Also, a therapeutic benefit is achieved with the eradication or amelioration of one or more of the physiological symptoms associated with the underlying disorder such that an improvement is observed in the patient, notwithstanding that the patient may still be afflicted with the underlying disorder. For prophylactic benefit, the compositions may be administered to a patient at risk of developing a particular disease, or to a patient reporting one or more of the physiological symptoms of a disease, even though a diagnosis of this disease may not have been made. A prophylactic effect includes delaying or eliminating the appearance of a disease or condition, delaying or eliminating the onset of symptoms of a disease or condition, slowing, halting, or reversing the progression of a disease or condition, or any combination thereof.
The term “in need of treatment” encompasses both therapeutic and prophylactic treatment. Thus, for example, and animal would be in need of treatment if the treatment would provide a prophylactic benefit, for instance where the animal is at risk of developing a disease or condition.
The term “physiological compartment” as used herein includes physiological structures, such as organs or organ groups or the fetal compartment, or spaces whereby a physiological or chemical barrier exists to exclude compounds or agents from the internal portion of the physiological structure or space. Such physiological compartments include the central nervous system, the fetal compartment and internal structures contained within organs, such as the ovaries and testes.
Therapeutic agents that may be used in compositions and methods of the invention include immunosuppressive agents, such as calcineurin inhibitors, e.g. tacrolimus, sirolimus, and the like, other immunomodulators, antineoplastics, amphetamines, antihypertensives, vasodilators, barbiturates, membrane stabilizers, cardiac stabilizers, glucocorticoids, antilipedemics, antiglycemics, cannabinoids, antidipressants, antineuroleptics, chemotherapeutic agents, antiinfectives, tolerogen, immunostimulants, drug acting on the blood and the blood-forming organs, hematopoietic agent, growth factor, mineral, and vitamin, anticoagulant, thrombolytic, antiplatelet drug, hormone, hormone antagonist, pituitary hormone, thyroid and antithyroid drug, estrogen and progestin, androgen, adrenocorticotropic hormone; adrenocortical steroid and synthetic analogs, insulin, oral hypoglycemic agents, calcium, phosphate, parathyroid hormone, vitamin D, calcitonin, and other compounds.

In some embodiments, the invention provides a liquid pharmaceutical composition for oral administration containing an effective amount of cyclosporin, an amount of phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin that is effective in reducing or eliminating a side effect of cyclosporin, and a pharmaceutically acceptable excipient.
In some embodiments, the invention provides a solid pharmaceutical composition for oral administration containing cyclosporin at about 100-800 mg, phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin at about 10-1000 mg and a pharmaceutically acceptable excipient.

Pharmaceutical compositions of the invention suitable for oral administration can be presented as discrete dosage forms, such as capsules, cachets, or tablets, or liquids or aerosol sprays each containing a predetermined amount of an active ingredient as a powder or in granules, a solution, or a suspension in an aqueous or non-aqueous liquid, an oil-in-water emulsion, or a water-in-oil liquid emulsion. Such dosage forms can be prepared by any of the methods of pharmacy, but all methods include the step of bringing the active ingredient into association with the carrier, which constitutes one or more necessary ingredients. In general, the compositions are prepared by uniformly and intimately admixing the active ingredient with liquid carriers or finely divided solid carriers or both, and then, if necessary, shaping the product into the desired presentation. For example, a tablet can be prepared by compression or molding, optionally with one or more accessory ingredients. Compressed tablets can be prepared by compressing in a suitable machine the active ingredient in a free-flowing form such as powder or granules, optionally mixed with an excipient such as, but not limited to, a binder, a lubricant, an inert diluent, and/or a surface active or dispersing agent. Molded tablets can be made by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent.
This invention further encompasses anhydrous pharmaceutical compositions and dosage forms comprising an active ingredient, since water can facilitate the degradation of some compounds. Anhydrous pharmaceutical compositions and dosage forms of the invention can be prepared using anhydrous or low moisture containing ingredients and low moisture or low humidity conditions. Pharmaceutical compositions and dosage forms of the invention which contain lactose can be made anhydrous if substantial contact with moisture and/or humidity during manufacturing, packaging, and/or storage is expected. An anhydrous pharmaceutical composition may be prepared and stored such that its anhydrous nature is maintained. Accordingly, anhydrous compositions may be packaged using materials known to prevent exposure to water such that they can be included in suitable formulary kits. Examples of suitable packaging include, but are not limited to, hermetically sealed foils, plastic or the like, unit dose containers, blister packs, and strip packs.
An active ingredient can be combined in an intimate admixture with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques. The carrier can take a wide variety of forms depending on the form of preparation desired for administration. In preparing the compositions for an oral dosage form, any of the usual pharmaceutical media can be employed as carriers, such as, for example, water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents, and the like in the case of oral liquid preparations (such as suspensions, solutions, and elixirs) or aerosols; or carriers such as starches, sugars, micro-crystalline cellulose, diluents, granulating agents, lubricants, binders, and disintegrating agents can be used in the case of oral solid preparations, in some embodiments without employing the use of lactose. For example, suitable carriers include powders, capsules, and tablets, with the solid oral preparations. If desired, tablets can be coated by standard aqueous or nonaqueous techniques.
Binders suitable for use in pharmaceutical compositions and dosage forms include, but are not limited to, corn starch, potato starch, or other starches, gelatin, natural and synthetic gums such as acacia, sodium alginate, alginic acid, other alginates, powdered tragacanth, guar gum, cellulose and its derivatives (e.g., ethyl cellulose, cellulose acetate, carboxymethyl cellulose calcium, sodium carboxymethyl cellulose), polyvinyl pyrrolidone, methyl cellulose, pre-gelatinized starch, hydroxypropyl methyl cellulose, microcrystalline cellulose, and mixtures thereof.
Examples of suitable fillers for use in the pharmaceutical compositions and dosage forms disclosed herein include, but are not limited to, talc, calcium carbonate (e.g., granules or powder), microcrystalline cellulose, powdered cellulose, dextrates, kaolin, mannitol, silicic acid, sorbitol, starch, pre-gelatinized starch, and mixtures thereof.
Disintegrants may be used in the compositions of the invention to provide tablets that disintegrate when exposed to an aqueous environment. Too much of a disintegrant may produce tablets which may disintegrate in the bottle. Too little may be insufficient for disintegration to occur and may thus alter the rate and extent of release of the active ingredient(s) from the dosage form. Thus, a sufficient amount of disintegrant that is neither too little nor too much to detrimentally alter the release of the active ingredient(s) may be used to form the dosage forms of the compounds disclosed herein. The amount of disintegrant used may vary based upon the type of formulation and mode of administration, and may be readily discernible to those of ordinary skill in the art. About 0.5 to about 15 weight percent of disintegrant, or about 1 to about 5 weight percent of disintegrant, may be used in the pharmaceutical composition. Disintegrants that can be used to form pharmaceutical compositions and dosage forms of the invention include, but are not limited to, agar-agar, alginic acid, calcium carbonate, microcrystalline cellulose, croscarmellose sodium, crospovidone, polacrilin potassium, sodium starch glycolate, potato or tapioca starch, other starches, pre-gelatinized starch, other starches, clays, other algins, other celluloses, gums or mixtures thereof.
Lubricants which can be used to form pharmaceutical compositions and dosage forms of the invention include, but are not limited to, calcium stearate, magnesium stearate, mineral oil, light mineral oil, glycerin, sorbitol, mannitol, polyethylene glycol, other glycols, stearic acid, sodium lauryl sulfate, talc, hydrogenated vegetable oil (e.g., peanut oil, cottonseed oil, sunflower oil, sesame oil, olive oil, corn oil, and soybean oil), zinc stearate, ethyl oleate, ethyl laureate, agar, or mixtures thereof. Additional lubricants include, for example, a syloid silica gel, a coagulated aerosol of synthetic silica, or mixtures thereof. A lubricant can optionally be added, in an amount of less than about 1 weight percent of the pharmaceutical composition.
When aqueous suspensions and/or elixirs are desired for oral administration, the essential active ingredient therein may be combined with various sweetening or flavoring agents, coloring matter or dyes and, if so desired, emulsifying and/or suspending agents, together with such diluents as water, ethanol, propylene glycol, glycerin and various combinations thereof.
The tablets can be uncoated or coated by known techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate can be employed. Formulations for oral use can also be presented as hard gelatin capsules wherein the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, for example, peanut oil, liquid paraffin or olive oil.
Surfactant which can be used to form pharmaceutical compositions and dosage forms of the invention include, but are not limited to, hydrophilic surfactants, lipophilic surfactants, and mixtures thereof. That is, a mixture of hydrophilic surfactants may be employed, a mixture of lipophilic surfactants may be employed, or a mixture of at least one hydrophilic surfactant and at least one lipophilic surfactant may be employed.
A suitable hydrophilic surfactant may generally have an HLB value of at least 10, while suitable lipophilic surfactants may generally have an HLB value of or less than about 10. An empirical parameter used to characterize the relative hydrophilicity and hydrophobicity of non-ionic amphiphilic compounds is the hydrophilic-lipophilic balance (“HLB” value). Surfactants with lower HLB values are more lipophilic or hydrophobic, and have greater solubility in oils, while surfactants with higher HLB values are more hydrophilic, and have greater solubility in aqueous solutions. Hydrophilic surfactants are generally considered to be those compounds having an HLB value greater than about 10, as well as anionic, cationic, or zwitterionic compounds for which the HLB scale is not generally applicable. Similarly, lipophilic (i.e., hydrophobic) surfactants are compounds having an HLB value equal to or less than about 10. However, HLB value of a surfactant is merely a rough guide generally used to enable formulation of industrial, pharmaceutical and cosmetic emulsions.
Hydrophilic surfactants may be either ionic or non-ionic. Suitable ionic surfactants include, but are not limited to, alkylammonium salts; fusidic acid salts; fatty acid derivatives of amino acids, oligopeptides, and polypeptides; glyceride derivatives of amino acids, oligopeptides, and polypeptides; lecithins and hydrogenated lecithins; lysolecithins and hydrogenated lysolecithins; phospholipids and derivatives thereof, lysophospholipids and derivatives thereof; camitine fatty acid ester salts; salts of alkylsulfates; fatty acid salts; sodium docusate; acyl lactylates; mono- and di-acetylated tartaric acid esters of mono- and di-glycerides; succinylated mono- and di-glycerides; citric acid esters of mono- and di-glycerides; and mixtures thereof.

In one embodiment, the composition may include a solubilizer to ensure good solubilization and/or dissolution of the therapeutic agent and/or phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin and to minimize precipitation of the therapeutic agent and/or phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin. This can be especially important for compositions for non-oral use, e.g., compositions for injection. A solubilizer may also be added to increase the solubility of the hydrophilic drug and/or other components, such as surfactants, or to maintain the composition as a stable or homogeneous solution or dispersion.
Examples of suitable solubilizers include, but are not limited to, the following: alcohols and polyols, such as ethanol, isopropanol, butanol, benzyl alcohol, ethylene glycol, propylene glycol, butanediols and isomers thereof, glycerol, pentaerythritol, sorbitol, mannitol, transcutol, dimethyl isosorbide, polyethylene glycol, polypropylene glycol, polyvinylalcohol, hydroxypropyl methylcellulose and other cellulose derivatives, cyclodextrins and cyclodextrin derivatives; ethers of polyethylene glycols having an average molecular weight of about 200 to about 6000, such as tetrahydrofurfuryl alcohol PEG ether (glycofurol) or methoxy PEG; amides and other nitrogen-containing compounds such as 2-pyrrolidone, 2-piperidone, .epsilon.-caprolactam, N-alkylpyrrolidone, N-hydroxyalkylpyrrolidone, N-alkylpiperidone, N-alkylcaprolactam, dimethylacetamide and polyvinylpyrrolidone; esters such as ethyl propionate, tributylcitrate, acetyl triethylcitrate, acetyl tributyl citrate, triethylcitrate, ethyl oleate, ethyl caprylate, ethyl butyrate, triacetin, propylene glycol monoacetate, propylene glycol diacetate, ε-caprolactone and isomers thereof, δ-valerolactone and isomers thereof, β-butyrolactone and isomers thereof; and other solubilizers known in the art, such as dimethyl acetamide, dimethyl isosorbide, N-methyl pyrrolidones, monooctanoin, diethylene glycol monoethyl ether, and water.
In some embodiments, the oral formulation is made from the aqueous composition of sulfoalkyl ether cyclodextrin-flavonoid such as Captisol™ and a phosphorylated polyphenol, for example phosphorylated pyrone analog such as a phosphorylated flavonoid, e.g. phosphorylated quercetin. The oral formulation can be an aqueous liquid for oral administration, or may be a solid formulation that is produced by drying the aqueous composition, for example by freeze-drying or lyophilization. Lyophilization is a freeze-drying process in which water is sublimed from the composition after it is frozen. The particular advantages of the lyophilization process are that biologicals and pharmaceuticals that are relatively unstable in aqueous solution can be dried without elevated temperatures (thereby eliminating the adverse thermal affects) and then stored in the dry state where there are few stability problems. Once the aqueous composition is dried, it can be handled, for example, as a dried powder. The dried powder can be further formulated into oral pharmaceutical compositions as described herein.
Mixtures of solubilizers may also be used. Examples include, but not limited to, triacetin, triethylcitrate, ethyl oleate, ethyl caprylate, dimethylacetamide, N-methylpyrrolidone, N-hydroxyethylpyrrolidone, polyvinylpyrrolidone, hydroxypropyl methylcellulose, hydroxypropyl cyclodextrins, ethanol, polyethylene glycol 200-100, glycofurol, transcutol, propylene glycol, and dimethyl isosorbide. Particularly preferred solubilizers include sorbitol, glycerol, triacetin, ethyl alcohol, PEG-400, glycofurol and propylene glycol.
The amount of solubilizer that can be included is not particularly limited. The amount of a given solubilizer may be limited to a bioacceptable amount, which may be readily determined by one of skill in the art. In some circumstances, it may be advantageous to include amounts of solubilizers far in excess of bioacceptable amounts, for example to maximize the concentration of the drug, with excess solubilizer removed prior to providing the composition to a patient using conventional techniques, such as distillation or evaporation. Thus, if present, the solubilizer can be in a weight ratio of 10%, 25%, 50%, 100%, or up to about 200% by weight, based on the combined weight of the drug, and other excipients. If desired, very small amounts of solubilizer may also be used, such as 5%, 2%, 1% or even less. Typically, the solubilizer may be present in an amount of about 1% to about 100%, more typically about 5% to about 25% by weight.
The composition can further include one or more pharmaceutically acceptable additives and excipients. Such additives and excipients include, without limitation, detackifiers, anti-foaming agents, buffering agents, polymers, antioxidants, preservatives, chelating agents, viscomodulators, tonicifiers, flavorants, colorants, odorants, opacifiers, suspending agents, binders, fillers, plasticizers, lubricants, and mixtures thereof.
In addition, an acid or a base may be incorporated into the composition to facilitate processing, to enhance stability, or for other reasons. Examples of pharmaceutically acceptable bases include amino acids, amino acid esters, ammonium hydroxide, potassium hydroxide, sodium hydroxide, sodium hydrogen carbonate, aluminum hydroxide, calcium carbonate, magnesium hydroxide, magnesium aluminum silicate, synthetic aluminum silicate, synthetic hydrocalcite, magnesium aluminum hydroxide, diisopropylethylamine, ethanolamine, ethylenediamine, triethanolamine, triethylamine, triisopropanolamine, trimethylamine, tris(hydroxymethyl)aminomethane (TRIS) and the like. Also suitable are bases that are salts of a pharmaceutically acceptable acid, such as acetic acid, acrylic acid, adipic acid, alginic acid, alkanesulfonic acid, amino acids, ascorbic acid, benzoic acid, boric acid, butyric acid, carbonic acid, citric acid, fatty acids, formic acid, fumaric acid, gluconic acid, hydroquinosulfonic acid, is ascorbic acid, lactic acid, maleic acid, oxalic acid, para-bromophenylsulfonic acid, propionic acid, p-toluenesulfonic acid, salicylic acid, stearic acid, succinic acid, tannic acid, tartaric acid, thioglycolic acid, toluenesulfonic acid, uric acid, and the like. Salts of polyprotic acids, such as sodium phosphate, disodium hydrogen phosphate, and sodium dihydrogen phosphate can also be used. When the base is a salt, the cation can be any convenient and pharmaceutically acceptable cation, such as ammonium, alkali metals, alkaline earth metals, and the like. Example may include, but not limited to, sodium, potassium, lithium, magnesium, calcium and ammonium.
Suitable acids are pharmaceutically acceptable organic or inorganic acids. Examples of suitable inorganic acids include hydrochloric acid, hydrobromic acid, hydriodic acid, sulfuric acid, nitric acid, boric acid, phosphoric acid, and the like. Examples of suitable organic acids include acetic acid, acrylic acid, adipic acid, alginic acid, alkanesulfonic acids, amino acids, ascorbic acid, benzoic acid, boric acid, butyric acid, carbonic acid, citric acid, fatty acids, formic acid, fumaric acid, gluconic acid, hydroquinosulfonic acid, isoascorbic acid, lactic acid, maleic acid, methanesulfonic acid, oxalic acid, para-bromophenylsulfonic acid, propionic acid, p-toluenesulfonic acid, salicylic acid, stearic acid, succinic acid, tannic acid, tartaric acid, thioglycolic acid, toluenesulfonic acid, uric acid and the like.
Pharmaceutical compositions for infection. In some embodiments, the invention provides a pharmaceutical composition for injection containing a combination of a therapeutic agent and a phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin, and a pharmaceutical excipient suitable for injection. Components and amounts of agents in the compositions are as described herein.
The forms in which the novel compositions of the present invention may be incorporated for administration by injection include aqueous or oil suspensions, or emulsions, with sesame oil, corn oil, cottonseed oil, or peanut oil, as well as elixirs, mannitol, dextrose, or a sterile aqueous solution, and similar pharmaceutical vehicles.
Aqueous solutions in saline are also conventionally used for injection. Ethanol, glycerol, propylene glycol, liquid polyethylene glycol, and the like (and suitable mixtures thereof), cyclodextrin derivatives, and vegetable oils may also be employed. The proper fluidity can be maintained, for example, by the use of a coating, such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. The prevention of the action of microorganisms can be brought about by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like.
In some embodiments, the injectable formulation is made from the aqueous composition of sulfoalkyl ether cyclodextrin-flavonoid such as Captisol™ and a phosphorylated polyphenol, for example phosphorylated pyrone analog such as a phosphorylated flavonoid, e.g. phosphorylated quercetin. Where the pharmaceutical composition for injection is made from the aqueous composition of sulfoalkyl ether cyclodextrin-flavonoid, pharmaceutical composition for injection can be made either as a liquid formulation or, may be dissolved into solution, and processed to form a solid formulation produced by removal of liquid from the liquid composition, for example by freeze drying or lyophilization. Having a dried, solid formulation can be advantageous for increasing the shelf-life. The solid formulation can then be re-dissolved into solution for injection The dried powder can be further formulated into pharmaceutical composition for injection as described herein.
Sterile injectable solutions are prepared by incorporating phosphorylated polyphenol and/or the therapeutic agent in the required amount in the appropriate solvent with various other ingredients as enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the various sterilized active ingredients into a sterile vehicle which contains the basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, the preferred methods of preparation are vacuum-drying and freeze-drying techniques which yield a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof.
Pharmaceutical compositions for topical (e.g. transdermal) delivery. In some embodiments, the invention provides a pharmaceutical composition for transdermal delivery containing a combination of a therapeutic agent and phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin, and a pharmaceutical excipient suitable for transdermal delivery. In some embodiments, the phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin is capable of reducing or eliminating the side effect of the therapeutic agent. In some embodiments, the phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin is a BTB transport protein modulator. Components and amounts of agents in the compositions are as described herein.
Compositions of the present invention can be formulated into preparations in solid, semi-solid, or liquid forms suitable for local or topical administration, such as gels, water soluble jellies, creams, lotions, suspensions, foams, powders, slurries, ointments, solutions, oils, pastes, suppositories, sprays, emulsions, saline solutions, dimethylsulfoxide (DMSO)-based solutions. In general, carriers with higher densities are capable of providing an area with a prolonged exposure to the active ingredients. In contrast, a solution formulation may provide more immediate exposure of the active ingredient to the chosen area.
The pharmaceutical compositions also may comprise suitable solid or gel phase carriers or excipients, which are compounds that allow increased penetration of, or assist in the delivery of, therapeutic molecules across the stratum corneum permeability barrier of the skin. There are many of these penetration-enhancing molecules known to those trained in the art of topical formulation. Examples of such carriers and excipients include, but are not limited to, humectants (e.g., urea), glycols (e.g., propylene glycol), alcohols (e.g., ethanol), fatty acids (e.g., oleic acid), surfactants (e.g., isopropyl myristate and sodium lauryl sulfate), pyrrolidones, glycerol monolaurate, sulfoxides, terpenes (e.g., menthol), amines, amides, alkanes, alkanols, water, calcium carbonate, calcium phosphate, various sugars, starches, cellulose derivatives, gelatin, and polymers such as polyethylene glycols.
Another preferred formulation for use in the methods of the present invention employs transdermal delivery devices (“patches”). Such transdermal patches may be used to provide continuous or discontinuous infusion of the transport protein modulator in controlled amounts, either with or without therapeutic agent. Thus, in some embodiments the invention provides a transdermal patch incorporating a phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin. In some embodiments the invention provides a transdermal patch incorporating a phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin in combination with a therapeutic agent, e.g. an immunosuppressant such as a calcineurin inhibitor.
The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art. See, e.g., U.S. Pat. Nos. 5,023,252, 4,992,445 and 5,001,139. Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents.
Pharmaceutical compositions for inhalation. Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. Preferably the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions in preferably pharmaceutically acceptable solvents may be nebulized by use of inert gases. Nebulized solutions may be inhaled directly from the nebulizing device or the nebulizing device may be attached to a face mask tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions may be administered, preferably orally or nasally, from devices that deliver the formulation in an appropriate manner.
Other pharmaceutical compositions. Pharmaceutical compositions may also be prepared from compositions described herein and one or more pharmaceutically acceptable excipients suitable for sublingual, buccal, rectal, intraosseous, intraocular, intranasal, epidural, or intraspinal administration. Preparations for such pharmaceutical compositions are well-known in the art. See, e.g., See, e.g., Anderson, Philip O.; Knoben, James E.; Troutman, William G, eds., Handbook of Clinical Drug Data, Tenth Edition, McGraw-Hill, 2002; Pratt and Taylor, eds., Principles of Drug Action, Third Edition, Churchill Livingston, New York, 1990; Katzung, ed., Basic and Clinical Pharmacology, Ninth Edition, McGraw Hill, 20037ybg; Goodman and Gilman, eds., The Pharmacological Basis of Therapeutics, Tenth Edition, McGraw Hill, 2001; Remingtons Pharmaceutical Sciences, 20th Ed., Lippincott Williams & Wilkins., 2000; Martindale, The Extra Pharmacopoeia, Thirty-Second Edition (The Pharmaceutical Press, London, 1999); all of which are incorporated by reference herein in their entirety.
B. Kits

The kits include a phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin, in suitable packaging. Other components that may be included are written material that can include instructions for use, discussion of clinical studies, listing of side effects, and the like. The kit may further contain a therapeutic agent that has a side effect. In some embodiments, the phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin is provided as separate compositions in separate containers within the kit. In some embodiments, the therapeutic agent and the phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin are provided as a single composition within a container in the kit. Suitable packaging and additional articles for use (e.g., measuring cup for liquid preparations, foil wrapping to minimize exposure to air, and the like) are known in the art and may be included in the kit.
In another aspect, the invention provides methods, including methods of treatment, methods of decreasing the concentration of a substance in a physiological compartment (e.g., methods of delaying the onset or preventing chronic neurodegenerative diseases), methods of enhancing a therapeutic effect of a substance, methods of delaying, preventing, reducing or eliminating tolerance or dependence in an animal that is administered a substance, methods of drug wash-out, and methods for identifying modulators of blood-brain barrier transport proteins.
For simplicity, some methods will be described in terms of reduction of a side effect of a substance. It is understood that the methods apply equally to exclusion of a substance from the fetal compartment, or reduction of fetal effects of a substance.
The term “animal” or “animal subject” as used herein includes humans as well as other mammals. The methods generally involve the administration of one or more drugs for the treatment of one or more diseases. Combinations of agents can be used to treat one disease or multiple diseases or to modulate the side-effects of one or more agents in the combination.
The term “treating” and its grammatical equivalents as used herein includes achieving a therapeutic benefit and/or a prophylactic benefit. By therapeutic benefit is meant eradication or amelioration of the underlying disorder being treated. Also, a therapeutic benefit is achieved with the eradication or amelioration of one or more of the physiological symptoms associated with the underlying disorder such that an improvement is observed in the patient, notwithstanding that the patient may still be afflicted with the underlying disorder. For prophylactic benefit, the compositions may be administered to a patient at risk of developing a particular disease, or to a patient reporting one or more of the physiological symptoms of a disease, even though a diagnosis of this disease may not have been made.
A. Methods of Treating Conditions
In some embodiments, the invention provides a method of treating a condition by administering to an animal in need of treatment an effective amount of a phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin sufficient to reduce or eliminate a side effect of the therapeutic agent. In some embodiments, the activator reduces or eliminates a plurality of side effects of the therapeutic agent. In some embodiments the animal is a mammal, e.g., a human.
The therapeutic agent and the phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin are co-administered. “Co-administration,” “administered in combination with,” and their grammatical equivalents, as used herein, encompasses administration of two or more agents to an animal so that both agents and/or their metabolites are present in the animal at the same time. Co-administration includes simultaneous administration in separate compositions, administration at different times in separate compositions, or administration in a composition in which both agents are present. Thus, in some embodiments, the phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin are administered in a single composition. In some embodiments, the therapeutic agent and the phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin are admixed in the composition. Typically, the therapeutic agent is present in the composition in an amount sufficient to produce a therapeutic effect, and the phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin is present in the composition in an amount sufficient to reduce a side effect of the therapeutic agent. In some embodiments, the therapeutic agent is present in an amount sufficient to exert a therapeutic effect and the phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin is present in an amount sufficient to decrease a side effect of the therapeutic agent by an average of at least about 5, 10, 15, 20, 25, 30, 40, 50, 60, 70, 80, 90, more than 90%, or substantially eliminate a side effect compared to the effect without the phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin.

The methods of the invention can be used to reduce the side effect and/or increase the effectiveness of a cannabinoid.
The methods of the invention can be used to reduce the side effect and/or increase the effectiveness of an antidepressant. In some embodiments, antidepressants cause the side effects of high blood sugar and diabetes. The methods of the invention can be used, for example to reduce these side effects. In some embodiments the therapeutic agent is an antidepressant selected from the group of aripiprazone (Abilify), nefazodone (Serzone), escitalopram oxalate (Lexapro), sertraline (Zoloft), escitalopram (Lexapro), fluoxetine (Prozac), bupropion (Wellbutrin, Zyban), paroxetine (Paxil), venlafaxine (Effexor), trazodone (Desyrel), amitriptyline (Elavil), citalopram (Celexa), duloxetine (Cymbalta), mirtazapine (Remeron), nortriptyline (Pamelor), imipramine (Tofranil), amitriptyline (Elavil), clomipramine (Anafranil), doxepin (Adapin), trimipramine (Surmontil), amoxapine (Asenidin), desipramine (Norpramin), maprotiline (Ludiomil), protryptiline (Vivactil), citalopram (Celexa), fluvoxamine (Luvox), phenelzine (Nardil), trancylpromine (Parnate), selegiline (Eldepryl).

In some cases, it can be an anticonvulsant that also has efficacy in the treatment of pain. The therapeutic agent can be, for example, acetazolamide (Diamox), carbamazepine (Tegretol), clobazam (Frisium), clonazepam (Klonopin/Rivotril), clorazepate (Tranxene-SD), diazepam (Valium), divalproex sodium (Depakote), ethosuximide (Zarontin), ethotoin (Peganone), felbamate (Felbatol), fosphenyloin (Cerebyx), gabapentin (Neurontin), lamotrigine (Lamictal), levetiracetam (Keppra), lorezepam (Ativan), mephenyloin (Mesantoin), metharbital (Gemonil), methsuximide (Celontin).

In some cases, the phosphorylated phenols of the invention are administered to diminish or eliminate a side effect of a therapeutic agent. In some cases where the phosphorylated phenol is administered to eliminate a side effect of a therapeutic agent it is the metabolite of the phosphorylated phenol that is partly or fully responsible for the elimination of the side effect. Where the metabolite of the phosphorylated polyphenol is responsible for the effect, the phosphorylated polyphenol can be acting as a prodrug.
A prodrug is a precursor which will undergo metabolic activation in vivo to the active drug. The phosphorylated compounds of the present invention can act as prodrugs, for example, where the phosphate moiety is cleaved in vivo to yield an active compound. Non-specific phosphatases such as alkaline phosphatases in mammals are capable of dephosphorylating phosphate prodrugs into the biologically active forms. The phosphorylation can aid in the administration of drug of low water solubility to warm blooded animals for therapeutic purposes under conditions of more effective absorption and bioavailability by formulation into a water soluble biolabile form (See, for example, Krogsgaard-Larsen, P. and Bundegaard, H., eds., A textbook of Drug Design and Drug Development, Harvard Academic Publishers, p. 148, 1991). In some cases, more specific phosphatases, and phosphatases localized in particular areas of an animal, such as in vascular endothelial cells can be utilized to control the timing and location of de-phosphorylation and release of the drug from the prodrug form (see, for example, U.S. Patent Application 20060100179.
In some embodiments, the phosphorylated polyphenol will have higher water solubility than the non-phosphorylated polyphenol. In some embodiments the phosphorylated polyphenol will have multiple phosphates and will have higher water solubility than the polyphenol with fewer phosphate groups. For example, quercetin aglycone has relatively low solubility in water, and relatively low solubility in the blood. The addition of a phosphate to quercetin will tend to improve the solubility of the quercetin in water and in the blood and thus increase its bioavailability. The addition of the phosphate group can increase water solubility by adding polarity, by adding an ionic substituent, and in some cases due to geometrical (molecular shape) factors. In some embodiments of the invention, the phosphorylated polyphenol is at least about 10%, 20%, 25%, 30%, 40%, 50%, 60%, 75%, 90%, or 100% or at least about 2, 3, 4 5, 10, 20, 50, 100, 1,000, or 10,000 times more water soluble than the corresponding non-phosphorylated polyphenol. In some embodiments of the invention, the phosphorylated polyphenol is at least about 10%, 20%, 25%, 30%, 40%, 50%, 60%, 75%, 90%, or 100% or at least about 2, 3, 4 5, 10, 20, 50, 100, 1,000, or 10,000 times more soluble in a bodily fluid than the corresponding non-phosphorylated polyphenol. Methods for determining solubility are well known in the art. Where the fluid is clear, optical methods may be used for determining solubility. It is also possible to determine solubility by a direct measurement of the dissolved component, for example by HPLC. The solubility may be dependent on pH. In some embodiments the pH of the solution is neutral pH. In some embodiments the pH is between 6.8 and 7.2, in some embodiments the pH is between 6.5 and 7.5, in some embodiments the pH is between 6.0 and 7.0, in some embodiments the pH is between 5 and 9, in some embodiments the pH is between 4 and 10, in some embodiments the pH is between 3 and 11, in some embodiments the pH is between 2 and 12. The biological fluids of the present invention can be any fluid in an animal. Non-limiting examples of biological fluids are: blood, lymph, saliva, mucus, gastric juice, urine, aqueous humor, and semen.
One embodiment of the invention is a method for the treatment of an animal by oral administration of a therapeutic agent and a phosphorylated polyphenol, e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin that is greater than about 10%, 20%, 25%, 30%, 40%, 50%, 60%, 75%, 90%, or 100% or about 2, 3, 4 5, 10, 20, 50, 100, 1,000, or 10,000 times more soluble in water than the corresponding non-phosphorylated polyphenol. One embodiment of the invention is a method for the treatment of an animal by oral administration of a therapeutic agent and a phosphorylated polyphenol, e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin that is greater than about 10%, 20%, 25%, 30%, 40%, 50%, 60%, 75%, 90%, or 100% or greater than about 2, 3, 4 5, 10, 20, 50, 100, 1,000, or 10,000 times more soluble in a bodily fluid than the corresponding non-phosphorylated polyphenol. In some embodiments the therapeutic agent is an immunosuppressive agent, e.g. a calcineurin inhibitor such as tacrolimus or sirolimus.
In some embodiments, the increased water solubility will result in increased solubility of the polyphenol in a bodily fluid. In some embodiments, the increased solubility in a bodily fluid will result in greater bioavailability of the phosphorylated polyphenol than for the corresponding non-phosphorylated polyphenol.
In some embodiments, the phosphorylated polyphenol will provide a longer half-life of drug effect than for a non-phosphorylated polyphenol. For example, and without being limited by mechanism, where a phosphorylated phenol is not an active BTB transport protein modulator, and its de-phosphorylated form is active as a BTB transport protein modulator, the amount of active form can depend on the rate of de-phosphorylation. If the rate of de-phosphorylation is relatively slow, the de-phosphorylation process can act to delay the delivery of the active form. Under these conditions, the phosphorylated form acts as a kind of reservoir for the active form of the drug, thus extending the half life of drug effect. It will be understood by those of skill in the art that the relative rates of de-phosphorylation and the relative rates of absorption, clearance, and volume of distribution of the phosphorylated and de-phosphorylated forms can influence the half life of drug effect for the drug. In some embodiments, the de-phosphorylation of the phosphorylated form can be used as a tool to control the timing and the area to which the active compound is delivered, allowing the control of the target concentration and of the maintenance dose.
In some embodiments, the phosphorylated form is also an active form, i.e., dephosphorylation is not necessary in order to achieve the desired modulation of side effects of a therapeutic agent. The phosphorylated form may be more active, equally active, or less active than the dephosphorylated form, and the effects of the phosphorylated form may be due to a combination of its own effect and the effect and timing of appearance of the dephosphorylated from. However, it will be understood that the modulation of one or more side effects and/or therapeutic effects of a therapeutic agent by the phosphorylated pyrone analogs, as described herein, is not limited by the mechanism by which it is achieved.
In some embodiments, the therapeutic agent and the phosphorylated polyphenol are administered, at least in part, as an ionic complex between an opiate or an immunomodulator and a phosphorylated polyphenol. In some cases, the administration of the ionic complex results in higher solubility and greater bioavailability than where the compounds are administered without comprising an ionic complex.
Administration of the therapeutic agent and the phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin may be any suitable means. If the agents are administered as separate compositions, they may be administered by the same route or by different routes. If the agents are administered in a single composition, they may be administered by any suitable route. In some embodiments, the agents are administered as a single composition by oral administration. In some embodiments, the agents are administered as a single composition by transdermal administration. In some embodiments, the agents are administered as a single composition by injection.
In some embodiments, the phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin is a side effect modulator, e.g. BTB transport protein modulator. BTB transport protein modulators are as described herein. In some embodiments, a phosphorylated polyphenol is used.

In some embodiments, the phosphorylated pyrone analog such as a phosphorylated flavonoid is phosphorylated quercetin, phosphorylated fisetin, phosphorylated 5,7-dideoxyquercetin, phosphorylated kaempferol, or phosphorylated galangin. In some embodiments, the phosphorylated pyrone analog such as a phosphorylated flavonoid is phosphorylated quercetin.

When a therapeutic agent and a phosphorylated phenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin that reduces or eliminates a side effect of the therapeutic agent are used in combination, any suitable ratio of the two agents, e.g., molar ratio, wt/wt ration, wt/volume ratio, or volume/volume ratio, as described herein, may be used.
In some embodiments of the methods of the invention, the invention provides a method of treating a condition by administering to an animal suffering from the condition an effective amount of tacrolimus and an amount of a BTB transport protein modulator sufficient to change the concentration of tacrolimus in a physiological compartment.

B. Methods of Modulating the Concentration of a Substance in a Physiological Compartment
The invention provides methods for reducing the concentration of a substance in a physiological compartment by selectively increasing efflux of the substance from the physiological compartment to an external environment. The physiological compartment preferably is a central nervous system or a fetal compartment.
In some embodiments, compositions of the invention may be administered chronically to an individual in order to prevent, delay the appearance, or slow or halt the progression of a chronic neurodegenerative condition. In some embodiments, compositions of the invention may be administered chronically to an individual in order to remove from the CNS one or more substances associated with a chronic neurodegenerative condition. In some embodiments, the neurodegenerative condition is prion disease, Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), ALS, multiple sclerosis, transverse myelitis, motor neuron disease, Pick's disease, tuberous sclerosis, lysosomal storage disorders, Canavan's disease, Rett's syndrome, spinocerebellar ataxias, Friedreich's ataxia, optic atrophy, or retinal degeneration. In some embodiments, the neurodegenerative disease is AD. In some embodiments, the substance associated with a neurodegenerative disease is amyloid beta. In some embodiments, a phosphorylated pyrone analog such as a phosphorylated flavonoid is administered to the individual, such as phosphorylated quercetin, phosphorylated isoquercetin, phosphorylated flavon, phosphorylated chrysin, phosphorylated apigenin, phosphorylated rhoifolin, phosphorylated diosmin, phosphorylated galangin, phosphorylated fisetin, phosphorylated morin, phosphorylated rutin, phosphorylated kaempferol, phosphorylated myricetin, phosphorylated taxifolin, phosphorylated naringenin, phosphorylated naringin, phosphorylated hesperetin, phosphorylated hesperidin, phosphorylated chalcone, phosphorylated phloretin, phosphorylated phlorizdin, phosphorylated genistein, phosphorylated 5,7-dideoxyquercetin, phosphorylated biochanin A, phosphorylated catechin, or phosphorylated epicatechin.

In some embodiments, the phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin is administered in a pharmaceutical composition with a pharmaceutically acceptable excipient at a dose of 100 mg-10,000 mg per day. Other dosages of phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin, as described herein, may also be used.
In some embodiments, the invention provides a method of increasing the concentration of a therapeutic agent in a non-CNS compartment by the administration of a phosphorylated polyphenols, e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid such as phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin. While not being bound by theory, a BTB transport protein activator can result in the exclusion of a compound or removal of compound from the CNS compartment. Because the compartments of the body are interconnected, where the compound, such as a therapeutic agent, is excluded from the CNS compartment, there can be more of the compound available to the periphery than where the compound is distributed into the periphery as well. In some embodiments, the concentration of therapeutic agent in a non-CNS compartment is at least about 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, or more than 95% higher than without the administration of a phosphorylated polyphenol, e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid such as phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin.
In some embodiments of the methods of the invention, the invention provides a method of treating a condition by administering to an animal suffering from the condition an effective amount of tacrolimus and an amount of a BTB transport protein modulator sufficient to change the concentration of tacrolimus in a physiological compartment. In some embodiments of the methods of the invention the physiological compartment is selected from the group consisting of blood, lymph nodes, spleen, peyer's patches, lungs, heart kidney, pancreas liver, and gull bladder. In some embodiments of the methods of the invention the BTB transport modulator decrease the clearance of tacrolimus from a compartment where the drug is exerting therapeutic effect.

This may be the case, e.g., in wash-out methods where the agent is introduced into an animal to quickly, for example to lower the side effect of a substance already present in the body. Typically, such administration will be by injection, e.g., intravenous injection, in order to introduce the agent quickly. However, other routes may be used as appropriate. A single dose of a phosphorylated polyphenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin may also be used when it is administered with the substance (e.g., a therapeutic agent that produces a side effect) for treatment of an acute condition.
In some embodiments, the phosphorylated polyphenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin is administered in multiple doses. Dosing may be about once, twice, three times, four times, five times, six times, or more than six times per day. Dosing may be about once a month, once every two weeks, once a week, or once every other day. In one embodiment the drug is an immunosuppressive. In another embodiment the immunosuppressive compound and the transport protein activator are administered together about once per day to about 6 times per day. In another embodiment the administration of the immunosuppressive compound and the transport protein activator continues for less than about 7 days. In yet another embodiment the administration continues for more than about 6, 10, 14, 28 days, two months, six months, or one year. In some cases, continuous dosing is achieved and maintained as long as necessary, e.g., intravenous administration of immunosuppressive in a post-operative situation.
Administration of the agents of the invention may continue as long as necessary. In some embodiments, an agent of the invention is administered for more than 1, 2, 3, 4, 5, 6, 7, 14, or 28 days. In some embodiments, an agent of the invention is administered for less than 28, 14, 7, 6, 5, 4, 3, 2, or 1 day. In some embodiments, an agent of the invention is administered chronically on an ongoing basis, e.g., for the treatment of chronic pain.
An effective amount of a phosphorylated polyphenol and an effective amount of a drug may be administered in either single or multiple doses by any of the accepted modes of administration of agents having similar utilities, including rectal, buccal, intranasal and transdermal routes, by intra-arterial injection, intravenously, intraperitoneally, parenterally, intramuscularly, subcutaneously, orally, topically, as an inhalant, or via an impregnated or coated device such as a stent, for example, or an artery-inserted cylindrical polymer.
The phosphorylated polyphenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin and the therapeutic agent may be administered in dosages as described herein (see, e.g., Compositions). Dosing ranges for therapeutic agents are known in the art. Dosing for the phosphorylated polyphenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin may be found by routine experimentation. For a phosphorylated pyrone analog such as a phosphorylated flavonoid, e.g., phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin, typical daily dose ranges are, e.g. about 1-5000 mg, or about 1-3000 mg, or about 1-2000 mg, or about 1-1000 mg, or about 1-500 mg, or about 1-100 mg, or about 10-5000 mg, or about 10-3000 mg, or about 10-2000 mg, or about 10-1000 mg, or about 10-500 mg, or about 10-200 mg, or about 10-100 mg, or about 20-2000 mg or about 20-1500 mg or about 20-1000 mg or about 20-500 mg, or about 20-100 mg, or about 50-5000 mg, or about 50-4000 mg, or about 50-3000 mg, or about 50-2000 mg, or about 50-1000 mg, or about 50-500 mg, or about 50-100 mg, about 100-5000 mg, or about 100-4000 mg, or about 100-3000 mg, or about 100-2000 mg, or about 100-1000 mg, or about 100-500 mg. In some embodiments, the daily dose of quercetin is about 100, 200, 300, 400, 500, 600, 700, 800, 900, or 1000 mg. In some embodiments, the daily dose of quercetin is 100 mg. In some embodiments, the daily dose of quercetin is 500 mg. In some embodiments, the daily dose of quercetin is 1000 mg. Daily dose range may depend on the form of phosphorylated pyrone analog such as a phosphorylated flavonoid, e.g., the carbohydrate moieties attached to the phosphorylated pyrone analog such as a phosphorylated flavonoid, and/or factors with which the phosphorylated pyrone analog such as a phosphorylated flavonoid is administered, as described herein.
In some embodiments, the phosphorylated polyphenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin is administered two to three times a day with an oral dose of about 500 mg or an intravenous dose of about 150 mg. In some embodiments the phosphorylated polyphenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin is administered about one hour or about 30 minutes prior to administration of the therapeutic agent. In some embodiments the phosphorylated polyphenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid, such as a phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin is administered such that it is in the bloodstream 30 minutes prior to administration of the therapeutic agent. This timing may be accomplished by administering the phosphorylated polyphenol and the therapeutic agent separately, or by administering the quercetin and agent in the same composition that is formulated such that quercetin reaches the bloodstream before the therapeutic agent.
The serum half-life for, e.g., quercetin aglycone, is known to be about 19-25 hours. Where a phosphorylated polyphenol of the invention has a serum half life in the same range, single dose accuracy is not crucial.
When a phosphorylated polyphenol e.g. phosphorylated pyrone analog such as a phosphorylated flavonoid such as phosphorylated quercetin, phosphorylated fisetin, or phosphorylated 5,7-dideoxyquercetin, is administered as a BTB transport modulator in a composition that comprises one or more therapeutic agents, and the therapeutic agent has a shorter half-life than BTB transport modulator, unit dose forms of the therapeutic agent and the BTB transport modulator may be adjusted accordingly. Thus, for example, if phosphorylated phenol with a serum half life similar to that of quercetin is given in a composition also containing, e.g., tramadol, a typical unit dose form is, e.g., 50 mg tramadol/100 mg phosphorylated phenol, or 50 mg tramadol/500 mg phosphorylated phenol. See e.g., Compositions.
Table 3 below, provides exemplary dosing schemes for selected immunosuppressive agents and quercetin phosphate. These dosages are provided by way of example only and do not limit the invention.
2-hydroxy-4-(3,5,7-trihydroxy-4-oxo-4H-chromen-2-yl)phenyl dihydrogen phosphate. A suspension of quercetin (1 g, 3.31 mmol) and triethylamine (2.3 mL, 16.5 mmol) in dichloromethane (100 mL) at room temperature is treated dropwise with a 10% solution of phosphorus oxychloride in dichloromethane (3.6 mL, 3.97 mmol). The resulting mixture is stirred overnight to afford a heterogeneous mixture along will a brown sticky precipitate. The LCMS of the solution showed clean conversion to a single species with the correct mass for the cyclic phosphate. The solution is separated and the solvent is removed in vacuo to give a yellow solid (presumably the TEA salt of cyclic phosphate). Some of the solid is taken and dissolved in water and a few drops of acetonitrile. Allowing this solution to sit overnight results in the hydrolytic ring opening of the cyclic phosphate to give acyclic phosphate as a yellow solid.
Quercetin dihydrate (30 g. 0.089 mol, 1 eq.) is added to dichloromethane (3 L) followed by triethylamine (69 mL, 0.49 mol, 5.5 eq.) in one portion. The mixture is stirred for 15 min, then phosphorus oxychloride (9.95 mL, 0.107 mol, 1.2 eq.) is added in one portion (mild exotherm). The mixture is heated to reflux for 15 min, the heat is removed and the mixture is stirred for 18 h at room temperature. The solution is decanted away from the gummy, black residue and is concentrated under vacuum.
The resultant solid from concentration of the decantate is added acetonitrile (500 mL) followed by water (50 mL) then 1N hydrochloric acid (approx. 20 mL) until a pH of about 5 is achieved. The solution is concentrated to a volume of about 120 mL. The residue is purified with a 600 g, C-18 reverse phase column with 60 mL injections in a gradient. The gradient is 100% water (1 L), 9:1 water:MeOH (1 L), 8:2 water:MeOH (1 L), 7:3 water:MeOH (1 L), 1:1 water:MeOH. The desired product begins to elute after about 500 mL of 1:1 water:MeOH. The fractions are combined and concentrated. The residue is dissolved in water (40 mL) and solid potassium carbonate (approx. 3 g) is added until pH=8. The pH is adjusted to about 2 with 50% sulfuric acid resulting in the formation of a precipitate. The solid is collected, which contained approximately 10% TEA. The solid is suspended in water (50 mL), and the pH is adjusted to about 8 with solid potassium carbonate to produce a yellow solution. The resultant yellow solution is treated dropwise with 50% sulfuric acid until a pH of about 2 is reached, resulting in the precipitation of a solid. The solid is collected and slurried in water (75 mL). The solid is collected and dried giving 4 g, representing 12% of quercetin-3′-O-phosphate. As described above, the quercetin-3′-O-phosphate is soluble at about 4 g in 50 mL of water at about pH 8, representing a solubility of 80 mg per mL. The identity of the compound is confirmed using 1H NMR, 31P NMR, and Mass Spectrometry, which gave an m/Z peak at (M+H)+ of 383.1.
Quercetin-3′-O-phosphate is dissolved in water at about pH 8. After 24 hours in water at pH 8, no degradation is seen by NMR after 24 hours at ambient temperature.
One set of 5 rats is treated from day 1 to day 25 with inert vehicle 2 intraperitoneally and treated from day 11 to day 25 with inert vehicle 1 intraperitoneally. A second set of 5 rats is treated from day 1 to day 25 with tacrolimus (Prograf®) at 0.5 mg/kg, and treated from day 11 to day 25 with inert vehicle 2. A third set 5 of rats is treated from day 1 to day 25 with tacrolimus (Prograf®) intraperitoneally at 0.5 mg/kg, and treated from day 11 to day 25 intraperitoneally with quercetin-3′-O-phosphate (Q-Phosphate) at 114 mg/kg. The blood glucose level in the rats is measured on days 1, 10, 15, 20, and 25. The results are shown in Tables 4-6 below and in
Tissue is removed from the kidney of rats treated with tacrolimus (Prograf®) at 0.5 mg/kg and inert vehicle, and from rats treated with tacrolimus (Prograf®) at 0.5 mg/kg and quercetin-3′-O-phosphate (Q-Phosphate) at 11 mg/kg, 28 mg/kg, and at 114 mg/kg for 25 days. The tissue from rats treated with tacrolimus and vehicle show significant vacuolation. The tissue from rats treated with Q-Phosphate and tacrolimus show no vacuoles.
A secondary pharmacological screening of molecules of interest at a fixed concentration is often practiced in the pharmaceutical industry in order to evaluate the effect of the compound on secondary targets that could result in untoward toxicity in-vivo. These secondary screens are well known in the art and can be carried out by labs which specialize in these tests such as MDS-Panlabs and CEREP. A secondary toxicity screen is performed with Quercetin-3′-O-phosphate at a concentration of 10 μM against 122 targets in enzyme, radioligand binding, and cellular assays by MDS Pharma Services by methods well known in the art. Inhibition is found in only the following targets (percent inhibition at 10 μM in parentheses): ATPase, Na+/K+, Heart, Pig (65%), Nitric Oxide Synthase, Endothelial (eNOS) (72%), Protein Tyrosine Kinase, FGFR2 (94%), Protein Tyrosine Kinase, FGFR1(96%), Protein Tyrosine Kinase, Insulin Receptor (91%), Protein Tyrosine Kinase, (82%), Protein Tyrosine Kinase, ZA70 (ZAP-70) (74%), UDP Glucuronosyltransferase, UGT1A1 (52%), Adenosine A1 (50%), Adrenergic α2A (57%), Dopamine D47 (51%), Peripheral Benzodiazepine Receptor (PBR) (53%), Transporter, Monoamine rabbit (68%), Serotonin (5-Hydroxytryptamine) 5-HT1A (62%).
The compound is additionally tested in AdenosineA1, AdrenergicA2A, DopamineD25, Histamine H1-, and μ-Opiate GTPγS functional assays using a concentration of 10 μM. The compound demonstrated 48% antagonist activity in the AdenosineA1 assay, and marked negative inhibition in the AdrenergicA2A assay, potentially indicating PAF-5 could be acting as an inverse agonist in this assay.
The findings of this toxicology screen indicate that Quercetin-3′-O-phosphate has low toxicity properties, especially in light of the fact that the concentration tested, 10 μM, is high as compared to a therapeutic dose (e.g. greater than ˜100 times).
Quercetin dihydrate (90 g. 266 mmol, 1.0 eq.) is added to dimethylformamide (900 mL), followed by triethylamine (210 mL, 1463 mmol, 5.5 eq.) in one portion. The mixture is cooled to about −1° C. by acetone/dry ice bath while stirring. Phosphorus oxychloride (30 mL, 319 mmol, 1.2 eq.) is slowly added via an addition funnel keeping the internal temperature below about 5° C. The mixture is carefully kept between −1° C. and 5° C. until the addition of phosphorus oxychloride completed. The acetone/dry ice bath is then removed and replace by an ice/water bath. The mixture is slowly warmed to room temperature over 18 h. To the solution is added 10% HCl (approx. 140 mL) until pH=5. The solution is concentrated and the solid is dissolved in water (approx. 160 mL).
The solution is purified over a 600 g, C-18 reverse phase column with 60 mL per injection. After each injection, the column is eleuted with the following gradient. (i) 100% deionized water (3 L), (ii) 10% MeOH in water (1 L), (iii) 20% MeOH in water (1 L), (iv) 30% MeOH in water (1 L), and (v) 1:1 water:MeOH (1 L). The desired product lutes in the 1 L fraction of 1:1 water:MeOH. This fraction is concentrated in vacuo.
The fractions containing the desired product are concentrated to approximately 1.5 L volume, solid sodium carbonate is added slowly until reaching pH 9 and the solution is stirred at room temperature for 15 min. The solution is cooled to 3° C. and 50% sulfuric acid added slowly until attaining pH 2. The solution is kept in the cold bath for 1 h and fine yellow solid precipitates.
The mixture is aliquoted into centrifuge bottles with 220 g in each bottle. The mixture is centrifuged and the supernatant is decanted. The yellow solids are suspended in 1 N HCl (200 mL) and centrifuged, the supernatant is decanted. The yellow solid is suspended in deionized water (200 mL), centrifuged and the supernatant decanted. The resultant solid is resuspended into deionized water, centrifuged and the supernatant decanted. The wet solid is frozen and lyophilized.
The crude dried material is suspended in anhydrous methanol and collected to afford the desired product. The filtrate contains other isomeric O-phosphates
