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.
This invention provides compositions and methods utilizing pyrone analogs and their metabolites. Pyrone analogs, for example, flavonoids can enhance the effectiveness of therapeutic agents, for example, immunosuppressants or analgesics when administered in combination with such agents (see U.S. patent application Ser. Nos. 11/281,771, 11/281,984, and 11/553,924, and “Soluble Pyrone Analogs Methods and Compositions” Attorney Docket No. 31423-716.102, “Phosphorylated Pyrone Analogs and Methods” Attorney Docket No. 31423-720.102, “Methods and Compositions for Therapeutic Treatment” Attorney Docket No. 31423-732.101, “Methods and Compositions for Therapeutic Treatment” Attorney Docket No. 31423-733.101, and “Methods and Compositions for Therapeutic Treatment” Attorney Docket No. 31423-734.101, all of which are herein incorporated by reference in their entirety). Pyrone analogs of the invention may be used to modulate an effect caused by the therapeutic agent; e.g., to treat an animal suffering from a condition (e.g. side effect) caused by administration of a therapeutic agent. In some therapeutic interventions, administration of a therapeutic agent to an animal, which treats a first condition or disorder, causes a side effect, e.g., a second condition or disorder having one or more symptoms distinct from those of the first condition or disorder. This invention also provides novel analogs of these compounds which can have increased effectiveness, e.g., increased modulatory activity, solubility, and/or bioavailability, particularly oral bioavailability. In some embodiments, the compounds act in combination with a therapeutic agent to reduce side effects and/or enhance the effectiveness of the therapeutic agent. The pyrone analogs of the invention may comprise a monocylic or bicyclic nucleus, which may have nitrogen or oxygen substitution within the ring, thus encompassing heteroaromatic compounds in the definition of the aromatic compounds of the invention. These compounds may further comprise an aromatic or heteroaromatic moiety attached to one of the ring carbon atoms. The novel pyrone analogs of the invention may additionally comprise substituents including carbohydrate derivatization on one or more of the hydroxyl moieties. In some embodiments of the invention, the compounds of the present invention can have increased time course of drug effect, in some cases having a longer half life of drug effect, thus prolonging the effects of reducing side effects and/or enhancing the effectiveness of therapeutic agents. In another embodiment of the invention, a carbohydrate derivatized pyrone analog of the invention is metabolized to a glucuronide derivative, which is more active, more bioavailable and/or confers a longer half life of drug effect. In a further embodiment of the invention, the glucuronide derivatized pyrone analog itself is used in the compositions and methods of the invention.
In one aspect, the invention provides compositions and methods utilizing pyrone analogs as agents which reduce or eliminate a side effect of one or more substances. In some embodiments, the invention provides compositions and methods utilizing a combination of a therapeutic agent and a pyrone analog of the invention and/or its metabolite that acts as an agent to reduce or eliminate one or more side effect of the therapeutic agent. Typically, the effect-decreasing agent is a modulator of a blood tissue barrier (BTB) or a placental barrier 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 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 immunosuppressant, such as a calcineurin inhibitor, e.g., cyclosporine, tacrolimus, or a tacrolimus analog. In some embodiments of the invention, the therapeutic agent is an analgesic agent, such as an opiate or a non-opiate analgesic. In some embodiments of the invention, the therapeutic agent is a non-analgesic agent. The polyphenol 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.
Typically, the use of a pyrone analog of the invention and/or its metabolite, 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, in some embodiments, 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 a pyrone analog of the invention and/or its metabolite acting, optionally while one or more side effects of the therapeutic agent is reduced or substantially eliminated. For example, in some embodiments, the analgesic effect of an analgesic agent is enhanced while one or more CNS 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 one or more compartments of the body, while retaining or even increasing the effective concentration of the agent in the other compartments.
A pyrone analog of the invention 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.
As used herein and in the appended claims, the singular forms “a,” “and,” and “the” include plural referents unless the context clearly dictates otherwise.

The compounds of the invention may be synthesized via several approaches, and the particular synthesis route is chosen depending on the substituent pattern of the desired compound. The routes are illustrated with selected members of the class of compounds of the invention, but can be used for other compounds described herein. Note that Scheme 1 is found at paragraph 222.
In this synthetic route, a benzyl protected ortho-hydroxyphenyl styrylketone 2-A is cyclized to yield a 3-hydroxy flavone using hydrogen peroxide and base. Deprotection via treatment with hydrogen and palladium catalysts yields a 3′-,4′-dihydroxyphenyl 3-hydroxy flavone 2-C. (See Chemical Research in Toxicology, 17(6), 795-804 (2004).)
Another approach to compounds of the invention is via acid catalyzed cyclization of an 1-ortho-hydroxyphenyl-3-aryl-1, 3, propanedione 3-A to yield a flavone analog 3-C, as is illustrated in Scheme 3. Benzyl protection of the dihydroxy substituents on the 3-aryl moiety is shown, but methyl ether protection may also be used. After cyclization is accomplished, the protecting groups are removed from compound 3-B. In the case of benzyl protection, treatment with hydrogen in the presence of a palladium is used. If methyl ether protection is used, treatment of the cyclized protected species analogous to compound 3-B with trimethylsilyl iodide will produce the final product 3-C. (See Chemical Research in Toxicology, 17(6), 795-804 (2004).)
Alternative cyclizations to yield flavone analogs may also be used and is illustrated in Scheme 4. Beta-ketoester 4-A is cyclized with 1, 3, 5, trihydroxybenzene using heat to yield the protected flavone 4-C. Deprotection with trimethylsilyl iodide yields a flavone 4-D. The same intermediate 4-C is obtained by reacting the acetylenic trihydroxybenzene 4-F with compound 4-E to yield the tricyclic intermediate 4-G. Reduction of 4-G with hydrogen over palladium yields 4-C, which can be converted to the flavone 4-D as before. (See Faming Zhuanli Shenquig Gongkai Shuomingshu 1666987 (2005), and Acta Chemica Scandinavica 49(7), 524-9 (1995).)
Key: Substituents described in Table 1 of exemplary compounds are abbreviated as shown herein.
Key: Substituents described in Table 2 of exemplary compounds of Formula D are abbreviated as shown herein.
The synthesis of compound 2-F is shown in Scheme 5. Vinylogous ketone 2-D is cyclized in the presence of hydrogen peroxide and base to form the dibenzyl protected flavonoid 2-E. Hydrogenolysis with hydrogen with palladium catalysis deprotects the benzyl ethers to yield the 3′,4′-dihydroxy phenyl pyrone analog 2-F.
The synthesis of pyrone analog 3-F is accomplished via synthetic steps as shown in Scheme 6. Propanedione 3-D is cyclized under acidic conditions to yield the 3-H dibenzyloxy flavone analog. Deprotection of the benzyl ethers via hydrogenolysis produces pyrone analog 3-F.
The trihydroxy benzene 4-B is condensed with propanedione 4-H to obtain the 3′,4′-dimethoxy phenyl flavone 4-I. Deprotection of the methyl ethers at the 3′ and 4′ positions with trimethylsilyl iodide produces pyrone analog 4-J.
An anesthetic wake up test is used to assess the reversal effect of modulator, PA, on the sedative effects of barbiturates, opioids, and benzodiazepines. This is a single blind, randomized, controlled animal trial. Approximately 48 rodents may be utilized throughout the study. Animals may be reused. However, a washout of 24 hours is required between exposures.
Twelve rodents can be utilized in each portion of this trial. Intravenous barbiturate (e.g. diprivan, pentobarbital, or phenobarbital) anesthesia is induced and titrated to spontaneous but slow respirations and lack of response to painful stimulation. Supplemental oxygen may be delivered. A maximum of 3 doses of intraperitoneal PA may be tested (low, medium, high) along with placebo. Once administered rodents are monitored with the help of stopwatch for time to awakening and return to normal respiratory rate. Once awakened, rodents are tested for criteria including time to withdrawal from painful stimulus and performance on rotarod.
This study may be repeated as a single agent trial with opioids (remifentanyl, fentanyl, morphine, etc) and benzodiazepines (diazepam, midazolam, lorazepam). This study can also be repeated as a multi agent trial utilizing one opioid, one benzodiazepine, and one barbiturate.
Opioids frequently produce adverse CNS side effects in ambulatory settings, providing a rationale for improving opioid analgesia by minimizing adverse effects. Pyrone analogs may activate PgP efflux of pump ligands at the blood brain barrier. In this pilot study, the hypothesis that pyrone analogs can improve the tolerability and safety of oxycodone without impairing analgesia is tested. Healthy subjects (up to approximately 65 individuals) undergoing third molar removal are randomly allocated to receive, for example, 500 mg oral PA or matching placebo at 1 hr prior to surgery. All subjects receive, for example, 10 mg oral oxycodone immediately prior to surgery. Oxycodone concentrations do not differ between groups prior to surgery, at 1 hr, or at 4 hr. Total Nausea and Vomiting Score (TNVS) is calculated for the time from dosing through 24 hr.
All of the methods disclosed and claimed herein can be made and executed without undue experimentation in light of the present disclosure. It will be apparent to those of skill in the art that variations may be applied without departing from the concept, spirit and scope of the invention. More specifically, it will be apparent that certain agents that both chemically and physiologically related may be substituted for the agents described herein while the same or similar results would be achieved. All such similar substitutes and modifications apparent to those skilled in the art are deemed to be within the spirit, scope and concept of the invention as defined by the appended claims.
