This invention provides macrocyclic compounds to treat medical disorders, such as complement-mediated disorders.
The complement system is a part of the innate immune system which does not adapt to changes over the course of the host's life, but is recruited and used by the adaptive immune system. For example, it assists, or complements, the ability of antibodies and phagocytic cells to clear pathogens. This sophisticated regulatory pathway allows rapid reaction to pathogenic organisms while protecting host cells from destruction. Over thirty proteins and protein fragments make up the complement system. These proteins act through opsonization (enhancing phagocytosis of antigens), chemotaxis (attracting macrophages and neutrophils), cell lysis (rupturing membranes of foreign cells), and agglutination (clustering and binding of pathogens together).
The complement system has three pathways: classical, alternative, and lectin. Complement Factor D plays an early and central role in activation of the alternative pathway of the complement cascade. Activation of the alternative complement pathway is initiated by spontaneous hydrolysis of a thioester bond within C3 to produce C3(H2O), which associates with Factor B to form the C3(H2O)B complex. Complement Factor D acts to cleave Factor B within the C3(H2O)B complex to form Ba and Bb. The Bb fragment remains associated with C3(H2O) to form the alternative pathway C3 convertase C3(H2O)Bb. Additionally, C3b generated by any of the C3 convertases also associates with Factor B to form C3bB, which Factor D cleaves to generate the later stage alternative pathway C3 convertase C3bBb. This latter form of the alternative pathway C3 convertase may provide important downstream amplification within all three of the defined complement pathways, leading ultimately to the recruitment and assembly of additional factors in the complement cascade pathway, including the cleavage of C5 to C5a and CSb. C5b acts in the assembly of factors C6, C7, C8, and C9 into the membrane attack complex, which can destroy pathogenic cells by lysing the cell.
The dysfunction of or excessive activation of complement has been linked to certain autoimmune, inflammatory, and neurodegenerative diseases, as well as ischemia-reperfusion injury and cancer. For example, activation of the alternative pathway of the complement cascade contributes to the production of C3a and C5a, both potent anaphylatoxins, which also have roles in a number of inflammatory disorders. Therefore, in some instances, it is desirable to decrease the response of the complement pathway, including the alternative complement pathway. Some examples of disorders mediated by the complement pathway include age-related macular degeneration (AMD), paroxysmal nocturnal hemoglobinuria (PNH), multiple sclerosis, and rheumatoid arthritis.
Age-related macular degeneration (AMD) is a leading cause of vision loss in industrialized countries. Based on a number of genetic studies, there is evidence of the link between the complement cascade and macular degeneration. Individuals with mutations in the gene encoding complement Factor H have a fivefold increased risk of macular degeneration and individuals with mutations in other complement factor genes also have an increased risk of AMD. Individuals with mutant Factor H also have increased levels of C-reactive protein, a marker of inflammation. Without adequate functioning Factor H, the alternative pathway of the complement cascade is overly activated leading to cellular damage.
Paroxysmal nocturnal hemoglobinuria (PNH) is a non-malignant, hematological disorder characterized by the expansion of hematopoietic stem cells and progeny mature blood cells that are deficient in some surface proteins. PNH erythrocytes are not capable of modulating their surface complement activation, which leads to the typical hallmark of PNH—the chronic activation of complement mediated intravascular anemia. Currently, only one product, the anti-C5 monoclonal antibody eculizumab, has been approved in the U.S. for treatment of PNH. However, many of the patients treated with eculizumab remain anemic, and many patients continue to require blood transfusions. In addition, treatment with eculizumab requires life-long intravenous injections.
Additional complement-mediated disorders include those classified under component 3 glomerulopathy (C3G). C3G is a recently defined entity comprised of dense deposit disease (DDD) and C3 glomerulonephritis (C3GN) which encompasses a population of chronic kidney diseases wherein elevated activity of the alternative complement pathway and terminal complement pathway results in glomerular deposits made solely of complement C3 and no immunoglobulin (Ig).
Immune-complex membranoproliferative glomerulonephritis (IC-MPGN) is a renal disease which shares many clinical, pathologic, genetic and laboratory features with C3G, and therefore can be considered a sister disease of C3G. In the majority of patients with IC-MPGN, an underlying disease or disorder—most commonly infections, autoimmune diseases, or monoclonal gammopathies—are identified to which the renal disease is secondary. Patients with idiopathic IC-MPGN can have low C3 and normal C4 levels, similar to those observed in C3G, as well as many of the same genetic or acquired factors that are associated with abnormal alternative pathway activity. Although there are current hypotheses suggesting that the majority of IC-MPGN is attributable to over activity of the classical pathway, those patients with a low C3 and a normal C4 are likely to have significant overactivity of the alternative pathway. IC-MPGN patients with a low C3 and a normal C4 may benefit from alternative pathway inhibition.
Other disorders that have been linked to the complement cascade include atypical hemolytic uremic syndrome (aHUS), hemolytic uremic syndrome (HUS), abdominal aortic aneurysm, hemodialysis complications, hemolytic anemia, or hemodialysis, neuromyelitis (NMO), myasthenia gravis (MG), fatty liver, nonalcoholic steatohepatitis (NASH), liver inflammation, cirrhosis, liver failure, dermatomyositis, and amyotrophic lateral sclerosis.
Factor D is an attractive target for inhibition or regulation of the complement cascade due to its early and essential role in the alternative complement pathway, and for its potential role in signal amplification within the classical and lectin complement pathways. Inhibition of Factor D effectively interrupts the pathway and attenuates the formation of the membrane attack complex.
While initial attempts have been made to develop inhibitors of Factor D, there are currently no clinically approved small molecule Factor D inhibitors. Examples of Factor D inhibitor compounds are described in the following disclosures.

Given the wide variety of medical disorders that are caused by detrimental immune or inflammatory responses, new compounds are needed for medical treatment.
This invention includes an active compound of Formula I, Formula II, Formula III, Formula IV, Formula V, Formula VI, Formula VII, or Formula VIII (described below) or a pharmaceutically acceptable salt, prodrug, isotopic analog, N-oxide, or isolated isomer thereof, optionally in a pharmaceutically acceptable composition, wherein each of the Formulas is a macrocyclic compound. In one embodiment, an active compound or its salt or composition, as described herein is used to treat a medical disorder which is an inflammatory or immune condition, a disorder mediated by the complement cascade (including a dysfunctional cascade), a disorder or abnormality of a cell that adversely affects the ability of the cell to engage in or respond to normal complement activity including the alternative complement pathway, or an undesired complement-mediated response to a medical treatment, such as surgery or other medical procedure or a pharmaceutical or biopharmaceutical drug administration, a blood transfusion, or other allogenic tissue or fluid administration.
These macrocyclic compounds can be used to treat such conditions in a host in need thereof, typically a human. The active compound may act as an inhibitor of the Complement Factor D cascade. In one embodiment, a method for the treatment of such a disorder is provided that includes the administration of an effective amount of a compound of Formula I, Formula II, Formula III, Formula IV, Formula V, Formula VI, Formula VII, or Formula VIII or a pharmaceutically acceptable salt, prodrug, isotopic analog, N-oxide, or isolated isomer thereof, optionally in a pharmaceutically acceptable composition, as described in more detail below.
In certain embodiments, compounds are provided that have minimal effect on BSEP (bile salt export pump protein) (e.g., with an IC50 of greater than about 20, 30, 40, 50, 60, 75 or 100 μM or greater), or with a therapeutic index of BSEP relative to complement D inhibition (e.g., IC50 inhibition of BSEP/IC50 inhibition of complement D inhibitor), of about at least 50, 100, 200, 300, 400, 500, 750 or 1000 or greater). BSEP inhibition correlates with cholestatic drug-induced liver injury. Certain compounds of the present invention with low BSEP inhibition have at least one R201.
In some embodiments, the compounds of the present invention exhibit minimal hydrolysis of the amide bond between the C ring and the B ring in vivo, for example, by including a proline that has a cis-substituent relative to the proline-carbonyl bond directed toward the B-ring. In certain embodiments, the cis-substituent is in the Q3 position or the Q2 position or is a group that bridges Q3 and Q2.
It has also been discovered that including a B-ring substituent in the position ortho to the amide (for example 2-(L1)-3-methyl-6-substituted-pyridine or 2-(L1)-3-cyclopropyl-6-substituted-pyridine) may decreases the potential for formation of reactive metabolites.
In one aspect of the invention, an R301 acylated embodiment of an active compound of the invention is provided that exhibits extended half-life or other advantageous pharmacokinetic properties, which may be achieved by albumin stabilization in vivo. In certain embodiments, the acylated analogue can include several linking moieties in linear, branched or cyclic manner. In some embodiments, either one or a series of amino acids is used as a linker to a terminal fatty acid. In one non-limiting example a non-natural amino acid, 8-amino-3,6-dioxaoctanoic acid (one or several in sequence) is covalently bound to the selected complement D inhibitor of the present invention through a functional group such as a carboxylic acid, sulfonyl, hydroxyl or amino group. See generally Lau, et al., “Discovery of the Once-Weekly Glucagon-Like Peptide-1 (GLP-1) Analogue Semiglutide”, J. Med. Chem., 2015, 58, 7370-7380. In this embodiment, the 8-amino-3,6-dioxaoctanoic acid or similar molecule is covalently linked to an aliphatic acid, including but not limited to a C16, C18, C20 aliphatic acid, or a dicarboxylic acid, including but not limited to a C8, C10, C12, C14, C16, C18 or C20 diacid. One or more amino acids can also be used in the selected configuration to add length or functionality. More generally, nonlimiting embodiments include the use of a divalent linker moiety such as a dicarboxylic acid, amino acid, diamine, hydroxycarboxylic acid, hydroxyamine, di-hydroxy compound, or other compound that has at least two functional groups that can link the parent molecule with another linking moiety, and which may be albumin or other protein stabilized in vivo. In some embodiments, 2, 3, 4 or 5 linking moieties are covalently bound in sequence, branched or cyclic fashion to the parent compound. In some embodiments, an R301 acyl group is located in a position of the active compound that does not significantly adversely affect the complement D inhibition of the molecule, for example, as (i) a substituent on the R32 group or (ii) a substituent on a C-ring, such as proline, or as a substituent on a substituent on the C-ring, such as on an R1, R2 or R3 substituent, including for example, on a bridged moiety such as a fused cyclopropyl on the proline ring. In certain embodiments, the acyl group has an aliphatic or heteroaliphatic carbon range of about C12, C14, C16, C18, C20, C22 or C24.
In one embodiment, the disorder is associated with the alternative complement cascade pathway. In yet another embodiment, the disorder is associated with the complement classical pathway. In a further embodiment, the disorder is associated with the complement lectin pathway. Alternatively, the active compound or its salt or prodrug may act through a different mechanism of action than the complement cascade, or in particular as a Complement Factor D inhibitor, to treat the disorder described herein.

For example, in one embodiment, the active compound may be used in combination with an adoptive cell transfer therapy to reduce an inflammatory response associated with such therapy, for example, a cytokine mediated response such as cytokine response syndrome. In one embodiment, the adoptive cell transfer therapy is a chimeric antigen receptor T-Cell (CAR T) or a dendritic cell used to treat a hematologic or solid tumor, for example, a B-cell related hematologic cancer. In one embodiment, the hematologic or solid tumor is acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), non-Hodgkin's lymphoma, chronic lymphocytic leukemia (CLL), pancreatic cancer, glioblastoma, or a cancer that expresses CD19. In one embodiment, the associated inflammatory response is a cytokine mediated response.
Another embodiment is provided that includes the administration of an effective amount of an active compound or a pharmaceutically acceptable salt, prodrug, isotopic analog, N-oxide, or isolated isomer thereof, optionally in a pharmaceutically acceptable composition to a host to treat an ocular, pulmonary, gastrointestinal, or other disorder that can benefit from topical or local delivery.

In some embodiments, the lipophilic active molecule is more soluble in the polymeric or other form of delivery system than in ocular fluid.
In other embodiments of the invention, an active compound provided herein can be used to treat or prevent a disorder in a host mediated by Complement Factor D, or by an excessive or detrimental amount of the complement-C3 amplification loop of the complement pathway. As examples, the invention includes methods to treat or prevent complement associated disorders that are induced by antibody-antigen interactions, a component of an immune or autoimmune disorder or by ischemic injury. The invention also provides methods to decrease inflammation or an immune response, including an autoimmune response, where mediated or affected by Factor D.

Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine, and chlorine, such as 2H, 3H, 11C, 13C, 14C, 15N, 18F 31P, 32P, 35S, 36CI, 125I respectively. In one embodiment, isotopically labelled compounds can be used in metabolic studies (with 14C), reaction kinetic studies (with, for example 2H or 3H), detection or imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT) including drug or substrate tissue distribution assays, or in radioactive treatment of patients. In particular, an 18F labeled compound may be particularly desirable for PET or SPECT studies. Isotopically labeled compounds of this invention and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations described below by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent.
By way of general example and without limitation, isotopes of hydrogen, for example, deuterium (2H) and tritium (3H) may optionally be used anywhere in described structures that achieves the desired result. Alternatively or in addition, isotopes of carbon, e.g., 13C and 14C, may be used. In one embodiment, the isotopic substitution is replacing hydrogen with a deuterium at one or more locations on the molecule to improve the performance of the drug, for example, the pharmacodynamics, pharmacokinetics, biodistribution, half-life, stability, AUC, Tmax, Cmax, etc. For example, the deuterium can be bound to carbon in a location of bond breakage during metabolism (an a-deuterium kinetic isotope effect) or next to or near the site of bond breakage (a β-deuterium kinetic isotope effect).
Isotopic substitutions, for example deuterium substitutions, can be partial or complete. Partial deuterium substitution means that at least one hydrogen is substituted with deuterium. In certain embodiments, the isotope is 80, 85, 90, 95 or 99% or more enriched in an isotope at any location of interest. In one embodiments deuterium is 80, 85, 90, 95 or 99% enriched at a desired location. Unless otherwise stated, the enrichment at any point is above natural abundance. And in an embodiment is enough to alter a detectable property of the drug in a human.
In one embodiment, the substitution of a hydrogen atom for a deuterium atom can be provided in any of A1, A2, A3, B1, B2, B3, C1, C2, C3, C4, L1, L2, or L3. In one embodiment, the substitution of a hydrogen atom for a deuterium atom occurs within any R group. In certain embodiment the R group is selected from any of R, R′, R1, R1′, R2, R2′, R3, R3′, R4, R5, R6, R6′, R7, R8, R8′, R9, R10, R11, R12, R13, R14, R15, R16, R17, R18, R18′, R19, R21, R22, R23, R24, R25, R30, R31, R32, R33, R34, R35, R36, R40, R41, R42, R43, R44, R45, R46, R47, R48, R49, R50, R51, R52, R52a, R53, R54, R71, R73, R74, R75, R101, R102, R103, R104, R201, R301, R302, R303, R304, R305, R306, R307, R308, and R309. For example, when any of R groups are, or contain for example through substitution, methyl, ethyl, or methoxy, the alkyl residue may be deuterated (in nonlimiting embodiments, CD3, CH2CD3, CD2CD3, CDH2, CD2H, CD3, CHDCH2D, CH2CD3, CHDCHD2, OCDH2, OCD2H, or OCD3 etc.). In certain other embodiments, an R group has a “‘” or an “a” designation, which in one embodiment can be deuterated. In certain other embodiments, when two substituents of the central core ring are combined to form a cyclopropyl ring, the unsubstituted methylene carbon may be deuterated.
The compound of the present invention may form a solvate with solvents (including water). Therefore, in one embodiment, the invention includes a solvated form of the active compound. The term “solvate” refers to a molecular complex of a compound of the present invention (including a salt thereof) with one or more solvent molecules. Nonlimiting examples of solvents are water, ethanol, dimethyl sulfoxide, acetone and other common organic solvents. The term “hydrate” refers to a molecular complex comprising a compound of the invention and water. Pharmaceutically acceptable solvates in accordance with the invention include those wherein the solvent of crystallization may be isotopically substituted, e.g. D2O, d6-acetone, d6-DMSO. A solvate can be in a liquid or solid form.
A dash (“—”) that is not between two letters or symbols is used to indicate a point of attachment for a substituent. For example, —(C═O)NH2 is attached through carbon of the keto (C═O) group.
The term “substituted”, as used herein, means that any one or more hydrogens on the designated atom or group is replaced with a moiety selected from the indicated group, provided that the designated atom's normal valence is not exceeded and the resulting compound is stable. For example, when the substituent is oxo (i.e., ═O) then two hydrogens on the atom are replaced. For example a pyridyl group substituted by oxo is a pyridone. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds or useful synthetic intermediates.
A stable active compound refers to a compound that can be isolated and can be formulated into a dosage form with a shelf life of at least one month. A stable manufacturing intermediate or precursor to an active compound is stable if it does not degrade within the period needed for reaction or other use. A stable moiety or substituent group is one that does not degrade, react or fall apart within the period necessary for use. Nonlimiting examples of unstable moieties are those that combine heteroatoms in an unstable arrangement, as typically known and identifiable to those of skill in the art.

Examples, of such salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, nitric and the like; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, mesylic, esylic, besylic, sulfanilic, 2-acetoxybenzoic, fumaric, toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, isethionic, HOOC—(CH2)n—COOH where n is 0-4, and the like, or using a different acid that produces the same counterion. Lists of additional suitable salts may be found, e.g., in Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., p. 1418 (1985).
The term “carrier” applied to pharmaceutical compositions/combinations of the invention refers to a diluent, excipient, or vehicle with which an active compound is provided.
A “pharmaceutically acceptable excipient” means an excipient that is useful in preparing a pharmaceutical composition/combination that is generally safe, acceptable for human consumption, and neither biologically nor otherwise inappropriate for administration to a host, typically a human. In one embodiment, an excipient is used that is acceptable for veterinary use.
A “patient” or “host” or “subject” is a human or non-human animal in need of treatment or prevention of any of the disorders as specifically described herein, including but not limited to by modulation of the Complement Factor D pathway or with a condition that is treatable with one of the compounds described herein. Typically the host is a human. A “patient” or “host” or “subject” also refers to for example, a mammal, primate (e.g., human), cows, sheep, goat, horse, dog, cat, rabbit, rat, mice, bird and the like.
A “prodrug” as used herein, means a compound which when administered to a host in vivo is converted into a parent drug described herein. As used herein, the term “parent drug” means any of the presently described chemical compounds herein. Prodrugs can be used to achieve any desired effect, including to enhance properties of the parent drug or to improve the pharmaceutic or pharmacokinetic properties of the parent, including to increase the half-life of the drug in vivo. Prodrug strategies provide choices in modulating the conditions for in vivo generation of the parent drug. Nonlimiting examples of prodrug strategies include covalent attachment of removable groups, or removable portions of groups, for example, but not limited to acylation, phosphorylation, phosphonylation, phosphoramidate derivatives, amidation, reduction, oxidation, esterification, alkylation, other carboxy derivatives, sulfoxy or sulfone derivatives, carbonylation or anhydride, among others. In certain embodiments, the prodrug renders the parent compound more lipophilic. In certain embodiments, a prodrug can be provided that has several prodrug moieties in linear, branched or cyclic manner. For example, nonlimiting embodiments include the use of a divalent linker moiety such as a dicarboxylic acid, amino acid, diamine, hydroxycarboxylic acid, hydroxyamine, di-hydroxy compound, or other compound that has at least two functional groups that can link the parent molecule with another prodrug moiety, and is typically biodegradable in vivo. In some embodiments, 2, 3, 4 or 5 prodrug biodegradable moieties are covalently bound in sequence, branched or cyclic fashion to the parent compound. Nonlimiting examples of prodrugs according to the present invention are formed with:
In one embodiment, a prodrug is provided by attaching a natural or non-natural amino acid to an appropriate functional moiety on the parent compound, for example, oxygen, nitrogen or sulfur, and typically oxygen or nitrogen, usually in a manner such that the amino acid can be cleaved in vivo to provide the parent drug. The amino acid can be used alone or covalently linked (straight, branched or cyclic) to one or more other prodrug moieties to modify the parent drug to achieve the desired performance, such as increased half-life, lipophilicity, or other drug delivery or pharmacokinetic properties. The amino acid can be any compound with an amino group and a carboxylic acid, which includes an aliphatic amino acid, alkyl amino acid, aromatic amino acid, heteroaliphatic amino acid, heteroallyl amino acid, or heterocyclic amino acid or heteroaryl amino acid.
“Providing a compound with at least one additional active agent,” for example, in one embodiment can mean that the compound and the additional active agent(s) are provided simultaneously in a single dosage form, provided concomitantly in separate dosage forms, or provided in separate dosage forms for administration. In one embodiment, the compound administrations are separated by some amount of time that is within the time in which both the compound and the at least one additional active agent are within the blood stream of a patient. In certain embodiments the compound and the additional active agent need not be prescribed for a patient by the same medical care worker. In certain embodiments the additional active agent or agents need not require a prescription. Administration of the compound or the at least one additional active agent can occur via any appropriate route, for example, oral tablets, oral capsules, oral liquids, inhalation, injection, suppositories, parenteral, sublingual, buccal, intravenous, intraaortal, transdermal, polymeric controlled delivery, non-polymeric controlled delivery, nano or microparticles, liposomes, and/or topical contact. In one embodiment, the instructions for administration in a form of combination therapy is provided in the drug labeling.
A “therapeutically effective amount” of a pharmaceutical composition/combination of this invention means an amount effective, when administered to a host, provides a therapeutic benefit such as an amelioration of symptoms or reduction or dimunition of the disease itself. In one embodiment, a therapeutically effective amount is an amount sufficient to prevent a significant increase or will significantly reduce the detectable level of Complement Factor D in the patient's blood, serum, or tissues.

In certain embodiments, any of the active compounds can be provided in its N-oxide form to a patient in need thereof. In one embodiment, an N-oxide of an active compound or a precursor of the active compound is used in a manufacturing scheme. In yet another embodiment, the N-oxide is a metabolite of administration of one of the active compounds herein, and may have independent activity. The N-oxide can be formed by treating the compound of interest with an oxidizing agent, for example a suitable peroxyacid or peroxide, to generate an N-oxide compound. For example, a heteroaryl group, for example a pyridyl group, can be treated with an oxidizing agent such as sodium percarbonate in the presence of a rhenium-based catalyst under mild reaction conditions to generate an N-oxide compound. A person skilled in the art will understand that appropriate protecting groups may be necessary to carry out the chemistry. See, Jain, S. L. et al., “Rhenium-Catalyzed Highly Efficient Oxidations of Tertiary Nitrogen Compounds to N-Oxides Using Sodium Percarbonate as Oxygen Source, Synlett, 2261-2663, 2006.
In one embodiment the N-oxide is in the A-Ring. In one embodiment the N-oxide is in the B-Ring. In one embodiment the N-oxide is on the R32 group.
In other embodiments, any of the active compounds with a sulfur can be provided in its sulfoxide or sulfone form to a patient in need thereof. In a different embodiment, a sulfoxide or sulfone of one of the active compounds or a precursor of the active compound is used in a manufacturing scheme. A sulfur atom in a selected compound as described herein can be oxidized to form a sulfoxide
or a sulfone
using known methods. For example, the compound 1,3,5-triazo-2,4,6-triphosphorine-2,2,4,4,6,6-tetrachloride (TAPC) is an efficient promoter for the oxidation of sulfides to sulfoxides. See, Bahrami, M. et al., “TAPC-Promoted Oxidation of sulfides and Deoxygenation of Sulfoxides”, J. Org. Chem., 75, 6208-6213 (2010). Oxidation of sulfides with 30% hydrogen peroxide catalyzed by tantalum carbide provides sulfoxides in high yields, see, Kirihara, A., et al., “Tantalum Carbide or Niobium Carbide Catalyzed Oxidation of Sulfides with Hydrogen Peroxide: Highly Efficient and Chemoselective Syntheses of Sulfoxides and Sulfones”, Synlett, 1557-1561 (2010). Sulfides can be oxidized to sulfones using, for example, niobium carbide as the catalyst, see, Kirihara, A., et al., “Tantalum Cardide or Niobium Carbide Catalyzed Oxidation of Sulfides with Hydrogen Peroxide: Highly Efficient and Chemoselective Syntheses of Sulfoxides and Sulfones”, Synlett, 1557-1561 (2010). Urea-hydrogen peroxide adduct is a stable inexpensive and easily handled reagent for the oxidation of sulfides to sulfones, see Varma, R. S. and Naicker, K. P., “The Urea-Hydrogen Peroxide Complex: Solid-State Oxidative Protocols for Hydroxylated Aldehydes and Ketones (Dakin Reaction), Nitriles, Sulfides, and Nitrogen Heterocycles”, Org. Lett., 1, 189-191 (1999). One skilled in the art will appreciate that other heteroatoms, such as nitrogen, may need to be protected and then deprotected while carrying out the oxidation of a sulfur atom to produce the desired compound.

The compounds of the present invention can be formulated as particles. In one embodiment the particles are or include microparticles. In an alternative embodiment the particles are or include nanoparticles.
In an additional alternative embodiment, common techniques for preparing particles include, but are not limited to, solvent evaporation, solvent removal, spray drying, phase inversion, coacervation, and low temperature casting. Suitable methods of particle formulation are briefly described below. Pharmaceutically acceptable excipients, including pH modifying agents, disintegrants, preservatives, and antioxidants, can optionally be incorporated into the particles during particle formation.
In one embodiment, the particles are derived through a solvent evaporation method. In this method, a compound described herein (or polymer matrix and one or more compounds described herein) is dissolved in a volatile organic solvent, such as methylene chloride. The organic solution containing a compound described herein is then suspended in an aqueous solution that contains a surface active agent such as poly(vinyl alcohol). The resulting emulsion is stirred until most of the organic solvent evaporated, leaving solid nanoparticles or microparticles. The resulting nanoparticles or microparticles are washed with water and dried overnight in a lyophilizer. Nanoparticles with different sizes and morphologies can be obtained by this method.
Pharmaceutical compositions which contain labile polymers, such as certain polyanhydrides, may degrade during the fabrication process due to the presence of water. For these polymers, methods which are performed in completely or substantially anhydrous organic solvents can be used to make the particles.
Solvent removal can also be used to prepare particles from a compound that is hydrolytically unstable. In this method, the compound (or polymer matrix and one or more compounds) is dispersed or dissolved in a volatile organic solvent such as methylene chloride. This mixture is then suspended by stirring in an organic oil (such as silicon oil) to form an emulsion. Solid particles form from the emulsion, which can subsequently be isolated from the supernatant. The external morphology of spheres produced with this technique is highly dependent on the identity of the drug.
In one embodiment an active compound as described herein is administered to a patient in need thereof as particles formed by solvent removal. In another embodiment the present invention provides particles formed by solvent removal comprising a compound of the present invention and one or more pharmaceutically acceptable excipients as defined herein. In another embodiment the particles formed by solvent removal comprise a compound of the present invention and an additional therapeutic agent. In a further embodiment the particles formed by solvent removal comprise a compound of the present invention, an additional therapeutic agent, and one or more pharmaceutically acceptable excipients. In another embodiment any of the described particles formed by solvent removal can be formulated into a tablet and then coated to form a coated tablet. In an alternative embodiment the particles formed by solvent removal are formulated into a tablet but the tablet is uncoated.
In one embodiment, the particles are derived by spray drying. In this method, a compound (or polymer matrix and one or more compounds) is dissolved in an organic solvent such as methylene chloride. The solution is pumped through a micronizing nozzle driven by a flow of compressed gas, and the resulting aerosol is suspended in a heated cyclone of air, allowing the solvent to evaporate from the micro droplets, forming particles. Microparticles and nanoparticles can be obtained using this method.
In one embodiment an active compound as described herein is administered to a patient in need thereof as a spray dried dispersion (SDD). In another embodiment the present invention provides a spray dried dispersion (SDD) comprising a compound of the present invention and one or more pharmaceutically acceptable excipients as defined herein. In another embodiment the SDD comprises a compound of the present invention and an additional therapeutic agent. In a further embodiment the SDD comprises a compound of the present invention, an additional therapeutic agent, and one or more pharmaceutically acceptable excipients. In another embodiment any of the described spray dried dispersions can be coated to form a coated tablet. In an alternative embodiment the spray dried dispersion is formulated into a tablet but is uncoated.
Particles can be formed from the active compound as described herein using a phase inversion method. In this method, the compound (or polymer matrix and one or more active compounds) is dissolved in a suitable solvent, and the solution is poured into a strong non-solvent for the compound to spontaneously produce, under favorable conditions, microparticles or nanoparticles. The method can be used to produce nanoparticles in a wide range of sizes, including, for example, from nanoparticles to microparticles, typically possessing a narrow particle size distribution.
In one embodiment, an active compound as described herein is administered to a patient in need thereof as particles formed by phase inversion. In another embodiment the present invention provides particles formed by phase inversion comprising a compound of the present invention and one or more pharmaceutically acceptable excipients as defined herein. In another embodiment the particles formed by phase inversion comprise a compound of the present invention and an additional therapeutic agent. In a further embodiment the particles formed by phase inversion comprise a compound of the present invention, an additional therapeutic agent, and one or more pharmaceutically acceptable excipients. In another embodiment any of the described particles formed by phase inversion can be formulated into a tablet and then coated to form a coated tablet. In an alternative embodiment the particles formed by phase inversion are formulated into a tablet but the tablet is uncoated.
Techniques for particle formation using coacervation are known in the art, for example, as described in GB-B-929 406; GB-B-929 40 1; and U.S. Pat. Nos. 3,266,987, 4,794,000, and 4,460,563. Coacervation involves the separation of a compound (or polymer matrix and one or more compounds) solution into two immiscible liquid phases. One phase is a dense coacervate phase, which contains a high concentration of the compound, while the second phase contains a low concentration of the compound. Within the dense coacervate phase, the compound forms nanoscale or microscale droplets, which harden into particles. Coacervation may be induced by a temperature change, addition of a non-solvent or addition of a micro-salt (simple coacervation), or by the addition of another polymer thereby forming an interpolymer complex (complex coacervation).
In one embodiment an active compound as described herein is administered to a patient in need thereof as particles formed by coacervation. In another embodiment the present invention provides particles formed by coacervation comprising a compound of the present invention and one or more pharmaceutically acceptable excipients as defined herein. In another embodiment the particles formed by coacervation comprise a compound of the present invention and an additional therapeutic agent. In a further embodiment the particles formed by coacervation comprise a compound of the present invention, an additional therapeutic agent, and one or more pharmaceutically acceptable excipients. In another embodiment any of the described particles formed by coacervation can be formulated into a tablet and then coated to form a coated tablet. In an alternative embodiment the particles formed by coacervation are formulated into a tablet but the tablet is uncoated.
Methods for very low temperature casting of controlled release microspheres are described in U.S. Pat. No. 5,019,400 to Gombotz et al. In this method, the compound is dissolved in a solvent. The mixture is then atomized into a vessel containing a liquid non-solvent at a temperature below the freezing point of the drug solution which freezes the compound droplets. As the droplets and non-solvent for the compound are warmed, the solvent in the droplets thaws and is extracted into the non-solvent, hardening the microspheres.
In one embodiment, a compound of the present invention is administered to a patient in need thereof as particles formed by low temperature casting. In another embodiment the present invention provides particles formed by low temperature casting comprising a compound of the present invention and one or more pharmaceutically acceptable excipients as defined herein. In another embodiment the particles formed by low temperature casting comprise a compound of the present invention and an additional therapeutic agent. In a further embodiment the particles formed by low temperature casting comprise a compound of the present invention, an additional therapeutic agent, and one or more pharmaceutically acceptable excipients. In another embodiment any of the described particles formed by low temperature casting can be formulated into a tablet and then coated to form a coated tablet. In an alternative embodiment the particles formed by low temperature casting are formulated into a tablet but the tablet is uncoated.
In one aspect of the present invention, an effective amount of an active compound as described herein is incorporated into a nanoparticle, e.g. for convenience of delivery and/or extended release delivery. The use of materials in nanoscale provides one the ability to modify fundamental physical properties such as solubility, diffusivity, blood circulation half-life, drug release characteristics, and/or immunogenicity. A number of nanoparticle-based therapeutic and diagnostic agents have been developed for the treatment of cancer, diabetes, pain, asthma, allergy, and infections. These nanoscale agents may provide more effective and/or more convenient routes of administration, lower therapeutic toxicity, extend the product life cycle, and ultimately reduce health-care costs. As therapeutic delivery systems, nanoparticles can allow targeted delivery and controlled release.
In addition, nanoparticle-based compound delivery can be used to release compounds at a sustained rate and thus lower the frequency of administration, deliver drugs in a targeted manner to minimize systemic side effects, or deliver two or more drugs simultaneously for combination therapy to generate a synergistic effect and suppress drug resistance. A number of nanotechnology-based therapeutic products have been approved for clinical use. Among these products, liposomal drugs and polymer-based conjugates account for a large proportion of the products.

The complement pathway enhances the ability of antibodies and phagocytic cells to clear microbes and damaged cells from the body. It is part of the innate immune system and in healthy individuals is an essential process. Inhibiting the complement pathway will decrease the body's immune system response. Therefore, it is an object of the present invention to treat autoimmune disorders by administering an effective does of an active compound or its salt or composition as described herein to a subject in need thereof.
In one embodiment the autoimmune disorder is caused by activity of the complement system. In one embodiment the autoimmune disorder is caused by activity of the alternative complement pathway. In one embodiment the autoimmune disorder is caused by activity of the classical complement pathway. In another embodiment the autoimmune disorder is caused by a mechanism of action that is not directly related to the complement system, such as the over-proliferation of T-lymphocytes or the over-production of cytokines.
Non-limiting examples of autoimmune disorders include: lupus, allograft rejection, autoimmune thyroid diseases (such as Graves' disease and Hashimoto's thyroiditis), autoimmune uveoretinitis, giant cell arteritis, inflammatory bowel diseases (including Crohn's disease, ulcerative colitis, regional enteritis, granulomatous enteritis, distal ileitis, regional ileitis, and terminal ileitis), diabetes, multiple sclerosis, pernicious anemia, psoriasis, rheumatoid arthritis, sarcoidosis, and scleroderma.
In one embodiment, an active compound or its salt or composition as described herein is used in the treatment of lupus. Non-limiting examples of lupus include lupus erythematosus, cutaneous lupus, discoid lupus erythematosus, chilblain lupus erythematosus, or lupus erythematosus-lichen planus overlap syndrome.
Lupus erythematosus is a general category of disease that includes both systemic and cutaneous disorders. The systemic form of the disease can have cutaneous as well as systemic manifestations. However, there are also forms of the disease that are only cutaneous without systemic involvement. For example, SLE is an inflammatory disorder of unknown etiology that occurs predominantly in women, and is characterized by articular symptoms, butterfly erythema, recurrent pleurisy, pericarditis, generalized adenopathy, splenomegaly, as well as CNS involvement and progressive renal failure. The sera of most patients (over 98%) contain antinuclear antibodies, including anti-DNA antibodies. High titers of anti-DNA antibodies are essentially specific for SLE. Conventional treatment for this disease has been the administration of corticosteroids or immunosuppressants.
There are three forms of cutaneous lupus: chronic cutaneous lupus (also known as discoid lupus erythematosus or DLE), subacute cutaneous lupus, and acute cutaneous lupus. DLE is a disfiguring chronic disorder primarily affecting the skin with sharply circumscribed macules and plaques that display erythema, follicular plugging, scales, telangiectasia and atrophy. The condition is often precipitated by sun exposure, and the early lesions are erythematous, round scaling papules that are 5 to 10 mm in diameter and display follicular plugging. DLE lesions appear most commonly on the cheeks, nose, scalp, and ears, but they may also be generalized over the upper portion of the trunk, extensor surfaces of the extremities, and on the mucous membranes of the mouth. If left untreated, the central lesion atrophies and leaves a scar. Unlike SLE, antibodies against double-stranded DNA (e.g., DNA-binding test) are almost invariably absent in DLE.
Multiple Sclerosis is an autoimmune demyelinating disorder that is believed to be T lymphocyte dependent. MS generally exhibits a relapsing-remitting course or a chronic progressive course. The etiology of MS is unknown, however, viral infections, genetic predisposition, environment, and autoimmunity all appear to contribute to the disorder. Lesions in MS patients contain infiltrates of predominantly T lymphocyte mediated microglial cells and infiltrating macrophages. CD4+ T lymphocytes are the predominant cell type present at these lesions. The hallmark of the MS lesion is plaque, an area of demyelination sharply demarcated from the usual white matter seen in MRI scans. Histological appearance of MS plaques varies with different stages of the disease. In active lesions, the blood-brain barrier is damaged, thereby permitting extravasation of serum proteins into extracellular spaces. Inflammatory cells can be seen in perivascular cuffs and throughout white matter. CD4+ T-cells, especially Th1, accumulate around postcapillary venules at the edge of the plaque and are also scattered in the white matter. In active lesions, up-regulation of adhesion molecules and markers of lymphocyte and monocyte activation, such as IL2-R and CD26 have also been observed. Demyelination in active lesions is not accompanied by destruction of oligodendrocytes. In contrast, during chronic phases of the disease, lesions are characterized by a loss of oligodendrocytes and hence, the presence of myelin oligodendrocyte glycoprotein (MOG) antibodies in the blood.
Diabetes can refer to either type 1 or type 2 diabetes. In one embodiment an active compound or its salt or composition as described herein is provided at an effective dose to treat a patient with type 1 diabetes. In one embodiment an active compound or its salt or composition as described herein is provided at an effective dose to treat a patient with type 2 diabetes.
Type 1 diabetes is an autoimmune disease. An autoimmune disease results when the body's system for fighting infection (the immune system) turns against a part of the body. The pancreas then produces little or no insulin.

In one embodiment, an active compound or its salt or composition as described herein is administered in combination or alteration with an omega-3 fatty acid or a peroxisome proliferator-activated receptor (PPARs) agonist. Omega-3 fatty acids are known to reduce serum triglycerides by inhibiting DGAT and by stimulating peroxisomal and mitochondrial beta oxidation. Two omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have been found to have high affinity for both PPAR-alpha and PPAR-gamma. Marine oils, e.g., fish oils, are a good source of EPA and DHA, which have been found to regulate lipid metabolism. Omega-3 fatty acids have been found to have beneficial effects on the risk factors for cardiovascular diseases, especially mild hypertension, hypertriglyceridemia and on the coagulation factor VII phospholipid complex activity. Omega-3 fatty acids lower serum triglycerides, increase serum HDL-cholesterol, lower systolic and diastolic blood pressure and the pulse rate, and lower the activity of the blood coagulation factor VII-phospholipid complex. Further, omega-3 fatty acids seem to be well tolerated, without giving rise to any severe side effects. One such form of omega-3 fatty acid is a concentrate of omega-3, long chain, polyunsaturated fatty acids from fish oil containing DHA and EPA and is sold under the trademark Omacor®. Such a form of omega-3 fatty acid is described, for example, in U.S. Pat. Nos. 5,502,077, 5,656,667 and 5,698,594, the disclosures of which are incorporated herein by reference.
Peroxisome proliferator-activated receptors (PPARs) are members of the nuclear hormone receptor superfamily ligand-activated transcription factors that are related to retinoid, steroid and thyroid hormone receptors. There are three distinct PPAR subtypes that are the products of different genes and are commonly designated PPAR-alpha, PPAR-beta/delta (or merely, delta) and PPAR-gamma. General classes of pharmacological agents that stimulate peroxisomal activity are known as PPAR agonists, e.g., PPAR-alpha agonists, PPAR-gamma agonists and PPAR-delta agonists. Some pharmacological agents are combinations of PPAR agonists, such as alpha/gamma agonists, etc., and some other pharmacological agents have dual agonist/antagonist activity. Fibrates such as fenofibrate, bezafibrate, clofibrate and gemfibrozil, are PPAR-alpha agonists and are used in patients to decrease lipoproteins rich in triglycerides, to increase HDL and to decrease atherogenic-dense LDL. Fibrates are typically orally administered to such patients. Fenofibrate or 2-[4-(4-chlorobenzoyl)phenoxy]-2-methyl-propanoic acid, 1-methylethyl ester, has been known for many years as a medicinally active principle because of its efficacy in lowering blood triglyceride and cholesterol levels.

Table 4 and Table 5 show illustrative Factor D inhibitors with characterizing data. The assay of Example 2 was used to determine the IC50's of the compounds. Other standard Factor D inhibition assays are also available. Three ***s are used to denote compounds with an IC50 less than 1 micromolar; two **s indicate compound with an IC50 between 1 micromolar and 10 micromolar, and one * denotes compounds with an IC50 greater than 10 micromolar.
Human Factor D (purified from human serum, Complement Technology, Inc.) at 80 nM final concentration is incubated with test compound at various concentrations for 5 min at room temperature in 50 mM Tris, 1M NaCl, pH 7.5. A synthetic substrate Z-L-Lys-SBzl and DTNB (Ellman's reagent) are added to final concentrations of 100 μM each. Absorbance at 405 nm (A405) is recorded at 30 second intervals for 30 minutes using a microplate spectrophotometer. IC50 values are calculated by nonlinear regression of Complement Factor D reaction rates as a function of test compound concentration.
The hemolysis assay was previously described by G. Ruiz-Gomez, et al., J. Med. Chem. (2009) 52: 6042-6052. Prior to the assay, the optimum concentration of Normal Human Serum (NHS) needed to achieve 100% lysis of rabbit erythrocytes (RE) is determined by titration. In the assay, NHS (Complement Technology) is diluted in GVB0 Buffer (0.1% gelatin, 5 mM Veronal, 145 mM NaCl, 0.025% NaN3, pH 7.3, Complement Technology) plus 10 mM Mg-EGTA and incubated with test compound at various concentrations for 15 min at 37° C. RE (Complement Technology) freshly suspended in GVB0 plus 10 mM Mg-EGTA are added to a final concentration of 1×108 cells/mL and reactions are incubated for 30 min at 37° C. Positive control reactions (100% lysis) consist of GVB0 plus 10 mM Mg-EGTA with NHS and RE but without test compound; negative control reactions (0% lysis) consist of GVB0 plus 10 mM Mg-EGTA with RE only. Samples are centrifuged at 2000 g for 3 min and supernatants collected. Absorbance at 405 nm (A405) is recorded using a microplate spectrophotometer. IC50 values are calculated by nonlinear regression from the percentage of hemolysis as a function of test compound concentration.
