Description

[Technical field]

[0001] (cross reference) This application claims the benefit of and priority to U.S. Provisional Patent Application No. 63 / 314,257, filed February 25, 2022, the contents of which are incorporated herein by reference in their entirety. [Background technology]

[0002] The IL-17 family is composed of six cytokines (IL-17A to IL-17F). Interleukin-17A (IL-17A) is a well-established pro-inflammatory cytokine that is involved in the induction of IL-6, IL-8, G-CSF, TNF-α, IL-1β, PGE2, and IFN-γ, as well as numerous chemokines and other effectors. IL-17A can form homodimers or heterodimers with its family member IL-17F and can bind to both IL-17 receptors, IL-17RA and IL-17RC, to mediate signal transduction. IL-17A is a major pathological cytokine expressed by Th17 cells, which are involved in inflammatory and autoimmune pathology, as well as CD8+ T cells, γδ cells, NK cells, NKT cells, macrophages, and dendritic cells. Furthermore, IL-17A and Th17 are required for defense against various microorganisms, despite their involvement in inflammatory and autoimmune disorders. Furthermore, IL-17A can act in concert with other inflammatory cytokines, such as TNF-α, IFN-γ, and IL-1β, to mediate pro-inflammatory effects.

[0003] To date, there are several biologics (secukinumab and ixekizumab) approved to modulate IL-17A for the treatment of inflammatory diseases such as psoriasis, ankylosing spondylitis, and psoriatic arthritis. These treatments require injection into patients because they are not easily absorbed by the intestine when taken orally. Furthermore, these approved biologic treatments have a high participation cost for patients, limiting their availability to patient populations in need. There are several small molecule modulators of IL-17A that are approved for oral administration. However, while these have the convenience of oral administration and lower entry cost to patients, they lack the efficacy of approved biologics. Thus, there is a need for the development of potent small molecule IL-17A modulators for the treatment of inflammatory diseases and other related disorders. Summary of the Invention

[0110] Chemical substances having carbon-carbon or carbon-nitrogen double bonds can exist in Z or E forms (or cis or trans forms). Additionally, some chemical substances can exist in various tautomeric forms. Unless otherwise specified, the compounds described herein are intended to include all Z-, E and tautomeric forms as well.

[0111] "Isomers" are different compounds that have the same molecular formula. "Stereoisomers" are isomers that differ only in terms of the arrangement of atoms in space. "Enantiomers" are a pair of stereoisomers that are non-superimposable mirror images of each other. A 1:1 mixture of a pair of enantiomers is a "racemic" mixture. The term "(±)" is used to designate racemic mixtures when appropriate. "Diastereoisomers" or "diastereomers" are stereoisomers that have at least two asymmetric atoms but are not mirror images of each other. Absolute stereochemistry is specified according to the Cahn-Ingold-Prelog RS system. When a compound is a pure enantiomer, the stereochemistry at each chiral carbon can be specified by either R or S. Resolved compounds whose absolute configuration is unknown can be designated (+) or (-) depending on the direction (dextrorotatory or levorotatory) they rotate plane polarized light at the wavelength of the sodium D line. Certain compounds described herein contain one or more asymmetric centers and can therefore give rise to enantiomers, diastereomers, and other stereoisomeric forms, which asymmetric centers can be defined in terms of absolute stereochemistry as (R)- or (S)-. Optically active (R)- and (S)-isomers can be prepared using chiral synthons or chiral reagents or resolved using conventional techniques. The optical activity of a compound can be analyzed via any suitable method, including, but not limited to, chiral chromatography and polarimetry, to determine the predominance of one stereoisomer over the other.

[0112] In cases where the stereochemistry is not specified in the chemical structure, molecules having stereocenters described herein include isomers such as enantiomers and diastereomers, mixtures of enantiomers including racemates, mixtures of diastereomers, and other mixtures thereof, to the extent that one skilled in the art can make by routine experimentation. In certain embodiments, single enantiomers or diastereomers, i.e., optically active forms, can be obtained by asymmetric synthesis or by resolution of racemic or diastereomeric mixtures. Resolution of racemic or diastereomeric mixtures, if possible, can be achieved by conventional methods such as, for example, crystallization in the presence of a resolving agent, or chromatography, for example, using a chiral high pressure liquid chromatography (HPLC) column. Furthermore, a mixture of two enantiomers enriched in one of the two enantiomers can be purified to obtain a more optically enriched form of the major enantiomer by recrystallization and / or trituration.

[0113] In certain embodiments, the compositions of the present disclosure may contain two or more enantiomers or diastereomers of a compound, where a single enantiomer or diastereomer accounts for at least about 70% by weight, at least about 80% by weight, at least about 90% by weight, at least about 98% by weight, or at least about 99% by weight or more of the total weight of all stereoisomers. Methods for producing substantially pure enantiomers are well known to those skilled in the art. For example, a single stereoisomer, e.g., an enantiomer, that is substantially free of its stereoisomer can be obtained by resolution of a racemic mixture using methods such as the formation of diastereomers using optically active resolving agents (Stereochemistry of Carbon Compounds, (1962) by EL Eliel, McGraw Hill; Lochmuller (1975) J. Chromatogr., 113(3):283-302). Racemic mixtures of chiral compounds can be separated and isolated by any suitable method, including, but not limited to, (1) formation of ionic diastereomeric salts with chiral compounds and separation by fractional crystallization or other methods, (2) formation of diastereomeric compounds with chiral derivatizing agents, separation of the diastereomers, and conversion to pure stereoisomers, and (3) direct separation under chiral conditions of the substantially pure or enriched stereoisomers. Another approach for separation of enantiomers is to use a Diacel chiral column and elution with an organic mobile phase as performed by Chiral Technologies (www.chiraltech.com) for a fee.

[0114] "Tautomer" refers to a molecule in which a proton transfer from one atom of the molecule to another atom of the same molecule is possible. The compounds presented herein exist as tautomers in certain embodiments. In situations where tautomerization is possible, a chemical equilibrium of tautomers exists. The exact ratio of tautomers depends on several factors, including physical conditions, temperature, solvent, and pH. Some examples of tautomeric equilibrium include the following: [ka]

[0115] The compounds disclosed herein may, in some embodiments, be present in different enriched isotopically forms, e.g., 2 H, 3 H, 11 C. 13 C, and / or 14 The compound is used in a form enriched in C content. In a particular embodiment, the compound is deuterated at at least one position. Such deuterated forms can be prepared by the procedures described in U.S. Patent Nos. 5,846,514 and 6,334,997. As described in U.S. Patent Nos. 5,846,514 and 6,334,997, deuteration can improve metabolic stability and / or efficacy, thus extending the duration of action of the drug.

[0116] In certain embodiments, the compounds disclosed herein comprise: 1 Some or all of the H atoms 2 H atom is substituted. Methods for the synthesis of deuterium-containing compounds are known in the art and include, by way of non-limiting example only, the following synthesis methods:

[0120] The present disclosure includes salts of compounds of formula (I), particularly pharma- ceutically acceptable salts. Compounds of the present disclosure may have sufficiently acidic functional groups, sufficiently basic functional groups, or both functional groups, and may react with any of a number of inorganic bases and inorganic and organic acids to form salts. Alternatively, compounds that are inherently charged (e.g., compounds with quaternary nitrogen) may form salts with suitable counterions, such as halides (e.g., bromide, chloride, or fluoride).

[0121] Synthetic chemistry transformations and methodologies useful for synthesizing the compounds described herein are known in the art and include, for example, those described in R. Larock, Comprehensive Organic Transformations (1989); T. W. Greene and P. G. Muts, Protective Groups in Organic Synthesis, 2d. Ed. 1991; Fieser and M. Fieser, Fieser and Fieser's Reagents for Organic Synthesis, 1994; and L. Paquette, ed., Encyclopedia of Reagents for Organic Synthesis, (1995).

[0122] Pharmaceutical preparations In some aspects, the disclosure provides pharmaceutical compositions comprising a compound of formula (I) or a salt and at least one pharma- ceutically acceptable excipient.

[0123] The pharmaceutical composition can be formulated using one or more physiologically acceptable carriers, including excipients and auxiliaries. The formulation can be modified according to the selected route of administration. The pharmaceutical composition containing the compound, salt or conjugate can be prepared, for example, by lyophilizing the compound, salt or conjugate, and mixing, dissolving, emulsifying, encapsulating or encapsulating the conjugate. The pharmaceutical composition can also contain the compound, salt or conjugate in free base form or in pharma-ceutically acceptable salt form.

[0124] Any one of the compounds of formula (I) or salts can be formulated into any suitable pharmaceutical formulation.The pharmaceutical formulations of the present disclosure typically contain active ingredients (e.g., any one of the compounds of formula (I) or salts) and one or more pharma- ceutically acceptable excipients or carriers, including, but not limited to, inert solid diluents and fillers, diluents, sterile aqueous solutions and various organic solvents, permeation enhancers, antioxidants, solubilizers, and adjuvants.

[0125] Pharmaceutical compositions may also be prepared from any one of the compounds or salts of formula (I) and one or more pharma- ceutically acceptable excipients suitable for transdermal, inhalation, sublingual, buccal, rectal, intraosseous, intraocular, intranasal, epidural, or intraspinal administration. Preparation of such pharmaceutical compositions is well known in the art. For example, 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 See Hill, 2003; 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).

[0126] Treatment method In certain embodiments, the compounds or salts of formula (I) or salts thereof can be used to treat or prevent diseases or conditions mediated directly or indirectly by IL-17A. Such diseases include inflammatory diseases and conditions, proliferative diseases (e.g., cancer), autoimmune diseases, and other diseases described herein. The methods generally include administering to a subject a therapeutically effective amount of a compound disclosed herein or a pharmaceutical composition thereof.

[0127] Increased levels of IL-17A have been associated with several conditions, including airway inflammation, rheumatoid arthritis (RA), osteoarthritis, bone erosion, intraperitoneal abscesses and adhesions, inflammatory bowel disease (IBD), allograft rejection, psoriasis, psoriatic arthritis, ankylosing spondylitis, certain types of cancer, angiogenesis, atherosclerosis, and multiple sclerosis (MS). Both IL-17A and IL-17R are upregulated in the synovial tissue of RA patients. IL-17A exerts its role in the pathogenesis of RA through IL-1-β and TNF-α-dependent and -independent pathways. IL-17A stimulates the secretion of other cytokines and chemokines, such as TNF-α, IL-1β, IL-6, IL-8, and Gro-α. IL-17A directly contributes to disease progression in RA. Injection of IL-17A into mouse knees promotes joint destruction independent of IL-1β activity (Ann Rheum Dis 2000,59:529-32). Anti-IL-1β antibodies have no effect on IL-17A-induced inflammation and joint damage (J Immunol 2001,167:1004-1013). In a SCW-induced mouse arthritis model, IL-17A induced inflammatory cell infiltration and proteoglycan depletion in wild-type and IL-1β knockout and TNF-α knockout mice. IL-17A knockout mice are phenotypically normal in the absence of antigen challenge but have significantly reduced arthritis after type II collagen immunization (J Immunol 2003,171:6173-6177). Increased levels of IL-17 A-secreting cells have also been observed in the facet joints of patients with ankylosing spondylitis (see H Appel et al., Arthritis Res Therap 2011, 13:R95).

[0128] In certain aspects, the disclosure provides a method of modulating IL-17A in a subject in need thereof, comprising administering to the subject a compound or salt of formula (I). In certain embodiments, the compound or salt of formula (I) inhibits the activity of IL-17A in a subject in need thereof.

[0129] In certain embodiments, the compound or salt of formula (I) is used to treat or prevent an inflammatory disease or condition. In certain embodiments, the compound or salt of formula (I) is administered to a subject in need thereof to treat an inflammatory disease or condition, such as psoriasis.

[0130] In certain embodiments, the compound or salt of formula (I) is used to treat or prevent an inflammatory disease or condition selected from psoriasis vulgaris, guttate psoriasis, inverse psoriasis, pustular psoriasis, erythrodermic psoriasis, psoriatic arthritis, ankylosing spondylitis, hidradenitis suppurativa, rheumatoid arthritis, palmoplantar psoriasis, spondyloarthritis, and non-infectious uveitis. In certain embodiments, the compound or salt of formula (I) is used to treat or prevent psoriasis. EXAMPLES

[0342] Preparation of stop solution: Cold (4° C.) acetonitrile (ACN) containing 200 ng / mL tolbutamide and 200 ng / mL labetalol as internal standards (IS) was used as the stop solution.

[0343] Assay procedure. Blank incubation plates (T60 and NCF60) were warmed for 10 min before use. Liver microsomes were diluted to 0.56 mg / mL in 100 mM phosphate buffer. 445 μL of microsome working solution (0.56 mg / mL) was transferred to pre-warmed "incubation" plates T60 and NCF60. "Incubation" plates T60 and NCF60 were then pre-incubated for 10 min at 37° C. with constant shaking. 54 μL of liver microsomes were transferred to blank plates, then 6 μL of nAPDH cofactor was added to the blank plates, followed by 180 μL of quench solution to the blank plates. 5 μL of compound working solution (100 μM) was added to the "incubation" plates (T60 and NCF60) containing microsomes and mixed thoroughly three times. 50 μL of buffer was added to the NCF60 plate and mixed thoroughly three times. Start timing: the plate was incubated at 37° C. for 60 minutes with shaking. To the “quench” plate T0, 180 μL of quench solution and 6 μL of NAPDH cofactor were added. The plate was cooled to prevent evaporation. The T60 plate was mixed thoroughly three times and 54 μL of the mixture was immediately removed to the “quench” plate at time 0 minutes. Then, 44 μL of NAPDH cofactor was added to the incubation plate (T60). Start timing: the plate was incubated at 37° C. for 60 minutes with shaking. Final concentrations of each component in the incubation medium: microsomes (0.5 mg protein / mL); test compound (1 μM); control compound (1 μM); ACN (0.99%); and DMSO (0.01%). At 5, 15, 30, 45, and 60 minutes, 180 μL of quench solution was added to the "quench" plate, mixed once, and 60 μL of sample per time point was transferred sequentially from the T60 plate to the "quench" plate. For the NCF60 plate, mixed once and at the 60 minute time point (start time 1:00:00 and end time 0:00:00), 60 μL of sample was transferred from the NCF60 incubation to the "quench" plate containing quench solution. Table 2.1 provides the reaction plate incubation times.

[0344] [Table 2]

[0345] All sampling plates were shaken for 10 min and then centrifuged at 4000 rpm for 20 min at 4°C. 80 μL of supernatant was transferred to 240 μL of HPLC water and mixed on a plate shaker for 10 min. Each bioanalytical plate was sealed and shaken for 10 min prior to LC-MS / MS analysis. First-order kinetics were used to determine half-lives and CL as reported in Table 2.6. int(mic) (μL / min / mg) was calculated.

[0346] Pharmacokinetics in rats Formulations for PO. An appropriate amount of test article is weighed and mixed with an appropriate volume of vehicle to obtain a clear solution or homogenous suspension; vortexing in a water bath or sonication may be used. Animals are dosed within 4 hours of preparation of the formulation. Formulation samples are removed from each formulation solution or suspension and transferred to 1.5 mL polypropylene microcentrifuge tubes, and doses are verified by LC / UV or LC-MS / MS.

[0347] Dose Administration. For PO administration, the dosage formulation is administered by oral gavage.

[0348] Blood collection. Each blood collection (approximately 0.2 mL per time point) is performed from the carotid artery cannula (CAC) of each animal into pre-chilled commercial EDTA-K2 tubes as anticoagulant, then placed on wet ice until centrifugation. Blood samples are processed for plasma by centrifugation at approximately 4° C. and 3200 g for 10 min. Plasma is collected and an aliquot of plasma from each rat is transferred to a pre-labeled 96-well plate or polypropylene tube, flash frozen on dry ice, and maintained at or below −60° C. until LC-MS / MS analysis. After the final collection, all plasma is stored in a freezer at approximately −80° C. until final analysis.

[0349] Plasma concentration versus time data are plotted on a graph and analyzed by a non-compartmental approach using the Phoenix WinNonlin 6.3 software program. The PO AUC calculation method used was linear / log trapezoidal, and the values ​​from this method are reported in Table 2.6. Trapezoidal: before tMAX (linear); after Tmax (log). Subregional Interpolation: before tMAX (linear); after Tmax (log).
