[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to International Patent Application No. PCT / CN2022 / 074435, filed January 27, 2022, and International Patent Application No. PCT / CN2021 / 076369, filed February 9, 2021, each of which is incorporated herein by reference in its entirety for all purposes.
[0002] FIELD OF THE INVENTION Provided herein are tetracyclic compounds useful for treating cancers that contain KRas mutations, compositions of such compounds, and methods of treating cancers that contain KRas mutations. [Background technology]
[0003] background Ras is a small GTP-binding protein that functions as a nucleotide-dependent switch in central growth signaling pathways. In response to extracellular signals, Ras undergoes GDP-bound (Ras) exchange, catalyzed by guanine nucleotide exchange factors (GEFs), particularly the SOS1 protein. GDP ) state to GTP-bound (Ras GTP ) state. Active Ras GTP Ras mediates its diverse growth-stimulatory functions through direct interaction with effectors, including Raf, PI3K, and the Ral guanine nucleotide dissociation stimulator. The intrinsic GTPase activity of Ras then hydrolyzes GTP to GDP, terminating Ras signaling. Ras GTPase activity can be further accelerated by interaction with GTPase-activating proteins (GAPs), including the neurofibromin 1 tumor suppressor.
[0004] Mutant Ras has reduced GTPase activity, which maintains Ras in an activated state, thereby promoting Ras-dependent signaling and cancer cell survival or proliferation. Mutations in Ras that affect its ability to interact with GAPs or convert GTP back to GDP result in sustained activation of the protein, resulting in sustained signals that promote continued growth and division. Because these signals lead to cell growth and division, overactive RAS signaling can ultimately lead to cancer. Mutations in any one of the three major RAS isoforms (HRas, NRas, or KRas) are common events in human tumorigenesis. Of the three Ras isoforms (K, N, and H), KRas is the most frequently mutated.
[0005] The most common KRas mutations are found at residues G12 and G13 in the P-loop and at residue Q61. G12D is a frequent mutation in the KRas gene (glycine-12 to aspartic acid). Ras mutations in cancer are associated with poor prognosis. Inactivation of oncogenic Ras in mice results in tumor regression. Therefore, Ras is widely considered to be an exceptionally important oncological target.
[0006] Therefore, there is an urgent need for therapies for G12D mutant KRas-mediated cancers. Summary of the Invention

[0054] The term "atropisomers" refers to two conformers resulting from hindered rotation about a single bond where the steric strain barrier to rotation can be high enough to allow isolation of each conformer.
[0055] Stereochemical definitions and conventions used herein generally follow S.P. Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984) McGraw-Hill Book Company, New York; and Eliel, E. and Wilen, S., "Stereochemistry of Organic Compounds," John Wiley & Sons, Inc., New York, 1994. Many organic compounds exist in optically active forms, i.e., they have the ability to rotate the plane of plane-polarized light. When describing optically active compounds, the prefixes D and L, or R and S, are used to denote the absolute configuration of the molecule about its chiral center(s). The prefixes d and l, or (+) and (-), are used to denote the sign of rotation of plane-polarized light by the compound, with (-) or 1 meaning that the compound is levorotatory. Compounds with the prefix (+) or d are dextrorotatory. For a given chemical structure, these stereoisomers are identical except that they are mirror images of each other. A specific stereoisomer may also be referred to as an enantiomer, and a mixture of such isomers is often called an enantiomeric mixture. A 50:50 mixture of enantiomers is called a racemic mixture or racemate, which may occur where there has been no stereoselection or stereospecificity in a chemical reaction or process. The terms "racemic mixture" and "racemate" refer to an equimolar mixture of two enantiomeric species, devoid of optical activity.

[0217] Compound synthesis The compounds described herein of the present disclosure, or stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts thereof, can be made by a variety of methods illustrated in the exemplary synthetic reaction schemes shown and described below. The starting materials and reagents used in the preparation of these compounds are generally available from commercial suppliers such as Aldrich Chemical Co., or are generally available from other sources such as Fieser and Fieser's Reagents for Organic Synthesis; Wiley & Sons: New York, vol. 1-21; R.C. LaRock, Comprehensive Organic Transformations, 2nd edition Wiley-VCH, New York 1999; Comprehensive Organic Synthesis, B. Trost and I. Fleming (Eds.) vol. 1-9 Pergamon, Oxford, 1991; Comprehensive Heterocyclic Chemistry, A.R. Katrittzky and C.W. Rees (Eds.) Pergamon, Oxford 1984, vol. 1-9; Comprehensive Heterocyclic Chemistry II, A.R. Katrittzky and C.W. Rees (Eds) Pergamon, Oxford 1996, vol. 1-11; and Organic Reactions, Wiley & Sons: New The compounds may be prepared by methods known to those skilled in the art according to procedures described in references such as, for example, John Wiley & Sons, 1991, vol. 1-40. The following synthetic reactions are merely illustrative of some of the methods by which the compounds described herein or pharmaceutically acceptable salts thereof may be synthesized, and various modifications to these synthetic reaction schemes may be made, which will be suggested to those skilled in the art with reference to the disclosure contained herein.
[0218] Synthetic chemistry transformations and protecting group methodologies (protection and deprotection) useful in synthesizing the compounds described herein and the necessary reagents and intermediates include those described, for example, in R. Larock, Comprehensive Organic Transformations, VCH Publishers (1989); T.W. Greene and P.G.M. Buts, Protective Groups in Organic Synthesis, 3 rd Ed., John Wiley and Sons (1999); and L. Paquette, ed., Encyclopedia of Reagents for Organic Synthesis, John Wiley and Sons (1995) and subsequent editions.
[0219] The compounds described herein, or stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts thereof, can be prepared singly or as compound libraries comprising at least two, e.g., 5 to 1,000 compounds, or 10 to 100 compounds. Libraries of the formulas described herein of the compounds described herein, or stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts thereof, can be prepared by combinatorial split and mix approaches or by multiple parallel syntheses using, e.g., either solution-phase or solid-phase chemistry. Thus, according to a further aspect, provided herein are compound libraries comprising at least two compounds described herein, or stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts thereof.
[0220] The examples provide illustrative methods for preparing the compounds described herein, or their stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts. Those skilled in the art will appreciate that other synthetic routes can be used to synthesize the compounds described herein, or their stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts. While specific starting materials and reagents are described and discussed in the examples, other starting materials and reagents can be substituted to provide a variety of derivatives and / or reaction conditions. Furthermore, many of the exemplary compounds prepared by the described methods can be further modified in light of this disclosure using conventional chemistry.
[0221] In preparing the compounds described herein, or their stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts, protection of remote functionalities (e.g., primary or secondary amines) of intermediates may be necessary. The need for such protection will vary depending on the nature of the remote functional group and the conditions of the preparation method. Suitable amino-protecting groups include acetyl, trifluoroacetyl, t-butoxycarbonyl (BOC), benzyloxycarbonyl (CBz), and 9-fluorenylmethylenoxycarbonyl (Fmoc). The need for such protection is readily determined. For a general description of protecting groups and their uses, see T.W. Greene, "Protective Groups in Organic Synthesis," John Wiley & Sons, New York (1991).
[0222] In the processes for preparing the compounds described herein, or stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts thereof, it may be advantageous to separate reaction products from one another and / or from starting materials. The desired products of each step or series of steps are separated and / or purified to the desired degree of homogeneity by techniques common in the art. Typically, such separations involve multiphase extraction, crystallization from a solvent or solvent mixture, distillation, sublimation, or chromatography. Chromatography can involve any number of methods, including, for example, reverse-phase and normal-phase, size exclusion, ion exchange, high-, medium-, and low-pressure liquid chromatography methods and apparatus, small-scale analytical, simulated moving bed (SMB) and preparative thin- or thick-layer chromatography, and small-scale thin-layer and flash chromatography techniques.
[0223] Another class of separation methods involves treating the mixture with a selected reagent to bind or otherwise render separable the desired product, unreacted starting materials, reaction by-products, etc. Such reagents include adsorbents or absorbents such as activated carbon, molecular sieves, ion exchange media, etc. Alternatively, the reagent may be an acid in the case of basic substances, a base in the case of acidic substances, a binding reagent such as an antibody, a binding protein, a selective chelating agent such as crown ethers, liquid-liquid ion extraction reagents (LIX), etc. The selection of an appropriate separation method depends on the properties of the materials involved, such as boiling point and molecular weight in distillation and sublimation, the presence or absence of polar functional groups in chromatography, the stability of the material in acidic and basic media in multiphase extraction, etc.
[0224] Diastereomeric mixtures can be separated into their individual diastereomers on the basis of their physical chemical differences by methods such as, for example, chromatography and / or fractional crystallization. Enantiomers can be separated by converting the enantiomeric mixture to a diastereomeric mixture by reaction with a suitable optically active compound (e.g., a chiral auxiliary such as a chiral alcohol or Moscher's acid chloride), separating the diastereomers, and converting the individual diastereomers to the corresponding pure enantiomers (e.g., by hydrolysis). Additionally, some of the compounds described herein, or their stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts, may be atropisomers (e.g., substituted biaryls). Enantiomers can also be separated using chiral HPLC columns.
[0225] A single stereoisomer, e.g., an enantiomer, can be obtained substantially free of its stereoisomer by resolving a racemic mixture using methods such as the formation of diastereomers with an optically active resolving agent (Eliel, E. and Wilen, S. "Stereochemistry of Organic Compounds," John Wiley & Sons, Inc., New York, 1994; Lochmuller, C.H., (1975) J. Chromatogr., 113(3):283-302). Racemic mixtures of chiral compounds described herein or pharmaceutically acceptable salts thereof can be separated and isolated by any suitable method, including: (1) formation of ionic diastereomeric salts with chiral compounds and separation by fractional recrystallization or other methods; (2) formation of diastereomeric compounds with chiral derivatizing agents, separation of diastereomers, and conversion to pure stereoisomers; and (3) separation of substantially pure or enriched stereoisomers under chiral conditions. Reference: Drug Stereochemistry, Analytical Methods and Pharmacology, Irving W. Wainer, Ed., Marcel Dekker, Inc., New York (1993).
[0226] In method (1), diastereomeric salts can be formed by reacting enantiomerically pure chiral bases, such as brucine, quinine, ephedrine, strychnine, and α-methyl-β-phenylethylamine (amphetamine), with asymmetric compounds containing acidic functional groups, such as carboxylic and sulfonic acids. The diastereomeric salts can be induced to separate by fractional recrystallization or ionic chromatography. To separate the optical isomers of amino compounds, the addition of chiral carboxylic or sulfonic acids, such as camphorsulfonic acid, tartaric acid, mandelic acid, or lactic acid, can form diastereomeric salts.
[0227] Alternatively, method (2) involves reacting the substrate to be resolved with one enantiomer of a chiral compound to form a diastereomeric pair (E. and Wilen, S., "Stereochemistry of Organic Compounds," John Wiley & Sons, Inc. (1994) p. 322). Diastereomeric compounds can be formed by reacting the asymmetric compound with an enantiomerically pure chiral derivatizing agent, such as a menthyl derivative, followed by separation and hydrolysis of the diastereomers to obtain the pure or enriched enantiomer. A method for determining optical purity involves making a chiral ester, such as a menthyl ester (e.g., (-)-menthyl chloroformate) of the racemic mixture in the presence of a base or Mosher's ester, α-methoxy-α-(trifluoromethyl)phenylacetate (Jacob III. J. Org. Chem. (1982) 47:4165), and testing for the presence of two atropisomeric enantiomers or diastereomers. 1This involves analyzing the H NMR spectrum. Stable diastereomers of atropisomeric compounds can be separated and isolated by normal-phase and reverse-phase chromatography following the method for separating atropisomeric naphthyl-isoquinolines (WO 96 / 15111). Method (3) allows the separation of racemic mixtures of two enantiomers by chromatography using a chiral stationary phase ("Chiral Liquid Chromatography" (1989) W. J. Lough, Ed., Chapman and Hall, New York; Okamoto, J. Chromatogr., (1990) 513:375-378). Enriched or purified enantiomers can be distinguished by methods used to distinguish other chiral molecules with asymmetric carbon atoms, such as optical rotation and circular dichroism.

Alternatively, other reactions disclosed herein or known in the art will be recognized as having applicability for preparing other compounds described herein and their pharmaceutically acceptable salts.
[0229] Pharmaceutical preparations Also provided herein are pharmaceutical compositions comprising a compound described herein, or a stereoisomer, atropisomer, tautomer, or pharmaceutically acceptable salt thereof, and one or more pharmaceutically acceptable excipients.
[0230] The compounds described herein, or their stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts, can be formulated in accordance with standard pharmaceutical practice as pharmaceutical compositions. Accordingly, further provided herein are pharmaceutical compositions comprising a compound described herein, or its stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts, and one or more pharmaceutically acceptable excipients.
[0231] A typical formulation is prepared by mixing a compound described herein or a pharmaceutically acceptable salt thereof with an excipient. Suitable carriers, diluents, and excipients include, but are not limited to, carbohydrates, waxes, water-soluble and / or swellable polymers, hydrophilic or hydrophobic materials, gelatin, oils, solvents, water, and other materials. The specific excipients used depend on the means and purpose for which the compound described herein or a pharmaceutically acceptable salt thereof is being administered. Solvents are generally selected based on solvents recognized as safe (GRAS) for mammalian administration. Generally, safe solvents are non-toxic aqueous solvents, such as water and other non-toxic solvents that are soluble or miscible in water. Suitable aqueous solvents include water, ethanol, propylene glycol, polyethylene glycol (e.g., PEG400, PEG300), and the like, and mixtures thereof. The formulation may also include one or more buffers, stabilizers, surfactants, wetting agents, lubricants, emulsifiers, suspending agents, preservatives, antioxidants, opaquing agents, glidants, processing aids, colorants, sweeteners, fragrances, flavoring agents, and other known additives to provide proper presentation of the drug (i.e., a compound described herein or a pharmaceutical composition thereof) or to aid in the manufacture of a pharmaceutical product (i.e., a medicament).
[0232] Formulations can be prepared using conventional dissolution and mixing procedures. For example, a bulk drug substance (i.e., a compound described herein or a pharmaceutically acceptable salt thereof, or a stabilized form thereof (e.g., a complex with a cyclodextrin derivative or other known complexing agent) is dissolved in a suitable solvent in the presence of one or more of the additives described above. The compounds described herein, or stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts thereof, are typically formulated into pharmaceutical dosage forms to provide easily controllable drug dosage and enable patient compliance with a prescribed regimen.
[0233] Pharmaceutical compositions (or formulations) for application may be packaged in a variety of ways depending on the method used to administer the drug. Generally, an article for distribution includes a container having disposed therein the pharmaceutical formulation in an appropriate form. Suitable containers include materials such as bottles (plastic and glass), sachets, ampoules, plastic bags, and metal cylinders. The container may also include a tamper-evident assembly to prevent unintentional access to the contents of the package. In addition, the container has disposed thereon a label that describes the contents of the container. The label may also include appropriate warnings.
[0234] Pharmaceutical formulations of the compounds described herein, or their stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts, can be prepared for various routes and types of administration. For example, a compound having the desired purity, or its stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts, can be mixed with one or more pharmaceutically acceptable excipients (Remington's Pharmaceutical Sciences (1980) 16th edition, Osol, A. Ed.), optionally in the form of a lyophilized formulation, a pulverized powder, or an aqueous solution. Formulation can be carried out by mixing the compound at ambient temperature, at an appropriate pH, and to the desired degree of purity with a physiologically acceptable carrier, i.e., a carrier that is nontoxic to recipients at the dosage and concentration used. The pH of the formulation will depend primarily on the specific application and the concentration of the compound, but can range from about 3 to about 8. For example, a formulation in acetate buffer at pH 5 may be a preferred embodiment.
[0235] Pharmaceutical compositions may generally be stored as solid compositions, lyophilized formulations or aqueous solutions.
[0236] The pharmaceutical compositions described herein can be formulated, prescribed, and administered in a manner consistent with full medical utility, i.e., in amounts, concentrations, schedules, courses, vehicles, and routes of administration. Factors to consider in this context include the particular disorder being treated, the particular mammal being treated, the clinical condition of the individual patient, the cause of the disorder, the site of drug delivery, the method of administration, the administration schedule, and other factors known to physicians. The effective amount of the administered compound, or its stereoisomer, atropisomer, tautomer, or pharmaceutically acceptable salt, will be governed by such considerations and will be the minimum amount necessary to ameliorate or treat the hyperproliferative disorder.
[0237] As a general proposition, an initial pharmaceutically effective amount of a parenterally administered compound, or a stereoisomer, atropisomer, tautomer, or pharmaceutically acceptable salt thereof, would be in the range of about 0.01 to 100 mg / kg, i.e., about 0.1 to 20 mg / kg, of patient body weight per day, with a typical initial range of the compound used being 0.3 to 15 mg / kg / day. In another embodiment, the pharmaceutical compositions described herein comprise an effective amount of a compound described herein, or a stereoisomer, atropisomer, tautomer, or pharmaceutically acceptable salt thereof, in an amount of about: 1 mg to 10 mg; 10 mg to 25 mg; 20 mg to 50 mg; 50 mg to 75 mg; 70 mg to 100 mg; 100 mg to 150 mg; 100 mg to 200 mg; 100 mg to 500 mg; 200 mg to 500 mg; 250 mg to 500 mg; 500 mg to 1000 mg; or 750 mg to 1000 mg.
[0238] Acceptable pharmaceutically acceptable excipients are nontoxic to recipients at the dosages and concentrations employed and include buffers (such as phosphate, citric acid, and other organic acids); antioxidants, including ascorbic acid and methionine; preservatives (such as octadecyldimethylbenzyl ammonium chloride; hexamethonium chloride; benzalkonium chloride; benzethonium chloride; phenol, butyl, or benzyl alcohol; alkyl parabens (such as methyl or propyl paraben); catechol; resorcinol; cyclohexanol; 3-pentanol; and m-cresol); low molecular weight (less than about 10 residues) polypeptides; proteins (such as serum albumin). , gelatin, or immunoglobulins; hydrophilic polymers (such as polyvinylpyrrolidone); amino acids (such as glycine, glutamine, asparagine, histidine, arginine, or lysine); monosaccharides, disaccharides, and other sugar chains (including glucose, mannose, or dextrin); chelating agents (such as EDTA); sugars (such as sucrose, mannitol, trehalose, or sorbitol); salt-forming counterions (such as sodium); metal complexes (e.g., Zn-protein complexes); and / or non-ionic surfactants (such as TWEEN™, PLURONICS™, or polyethylene glycol (PEG)). The active pharmaceutical ingredient may also be incorporated into microcapsules prepared, for example, by coacervation techniques or by interfacial polymerization, e.g., hydroxymethylcellulose or gelatin microcapsules and poly(methyl methacrylate) microcapsules, respectively, colloidal drug delivery systems (e.g., liposomes, albumin microspheres, microemulsions, nanoparticles, and nanocapsules), or macroemulsions. Such techniques are disclosed in Remington's Pharmaceutical Sciences 16th edition, Osol, A. Ed. (1980).
[0239] Sustained-release preparations of the compounds described herein or their pharmaceutically acceptable salts may also be prepared. Suitable examples of sustained-release formulations include semipermeable matrices of solid hydrophobic polymers containing the compounds described herein or their pharmaceutically acceptable salts, which matrices are in the form of shaped articles such as films or microcapsules. Examples of sustained-release matrices include polyesters, hydrogels (e.g., poly(2-hydroxyethyl-methacrylate) or poly(vinyl alcohol)), polylactides (U.S. Pat. No. 3,773,919), copolymers of L-glutamic acid and γ-L-ethyl glutamate, non-degradable ethylene vinyl acetate, degradable lactic acid-glycolic acid copolymers such as LUPRON DEPOT™ (injectable microspheres composed of lactic acid-glycolic acid copolymer and leuprolide acetate), and poly-D-(-)-3-hydroxybutyric acid.
[0240] Formulations include those suitable for the routes of administration detailed herein. Formulations may conveniently be presented in unit dosage form and may be prepared by any method. Techniques and formulations are generally found in Remington's Pharmaceutical Sciences (Mack Publishing Co., Easton, PA). Such methods include the step of bringing into association the active ingredient with the carrier, which constitutes one or more accessory ingredients. In general, formulations are prepared by uniformly and intimately bringing into association the active ingredient with liquid carriers or finely divided solid carriers, or both, and then, if necessary, shaping the product.
[0241] Formulations of the compounds described herein, or their stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts, suitable for oral administration can be prepared as discrete units such as pills, capsules, cachets, or tablets, each containing a predetermined amount of such compound, or its stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts. Compressed tablets can be prepared by compressing in a suitable machine the active ingredient in free-flowing form as a powder or granules, optionally mixed with a binder, lubricant, inert diluent, preservative, surfactant, or dispersing agent. Molded tablets can be made by molding in a suitable machine a mixture of moistened powdered active ingredient and an inert liquid diluent. Tablets may optionally be coated or grooved, and are optionally formulated to provide slow or controlled release of the active ingredient therefrom. Tablets, troches, lozenges, aqueous or oily suspensions, dispersible powders or granules, emulsions, hard or soft capsules, such as gelatin capsules, syrups, or elixirs may be prepared for oral use. Formulations of the compounds described herein or their pharmaceutically acceptable salts intended for oral use may be prepared according to any method for preparing pharmaceutical compositions, and such compositions may contain one or more agents, including sweeteners, flavoring agents, coloring agents, and preservatives, to provide a palatable preparation. Tablets containing the active ingredient mixed with non-toxic pharmaceutically acceptable additives suitable for tablet manufacture are acceptable. These additives may be, for example, inert diluents such as calcium carbonate or sodium carbonate, lactose, calcium phosphate or sodium phosphate, granulating agents and disintegrating agents such as corn starch or alginic acid, binders such as starch, gelatin, or acacia, and lubricants such as magnesium stearate, stearic acid, or talc. Tablets may be uncoated or may be coated by known techniques including microencapsulation 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 alone or with a wax may be employed.
[0242] For treatment of the eye or other external tissues, e.g., mouth and skin, the formulations are preferably applied as a topical ointment or cream containing the active ingredient in an amount of 0.075 to 20% w / w. When formulated in an ointment, the active ingredient can be used with either a paraffinic or water-miscible ointment base. Alternatively, the active ingredient can be formulated into a cream with an oil-in-water cream base. If desired, the aqueous phase of the cream base can contain a polyhydric alcohol, i.e., an alcohol having two or more hydroxyl groups, such as propylene glycol, butane-1,3-diol, mannitol, sorbitol, glycerol, polyethylene glycol (including PEG 400), and mixtures thereof. Topical formulations can optionally contain a compound that enhances absorption or penetration of the active ingredient through the skin or other affected areas. Examples of such skin penetration enhancers include dimethyl sulfoxide and related analogues. The oily phase of the emulsions of the compositions provided herein can be constituted from known ingredients in a known manner. The phase may simply comprise an emulsifier, but preferably comprises a mixture of at least one emulsifier with a fat or oil, or both a fat and an oil. Preferably, a hydrophilic emulsifier is included together with a lipophilic emulsifier that acts as a stabilizer. It is also preferred to include both an oil and a fat. Taken together, the emulsifier, with or without a stabilizer, constitutes the so-called emulsifying wax, and the wax together with the oil and fat constitutes the so-called emulsifying ointment base, which forms the oily dispersed phase of the cream formulation. Suitable emulsifiers and emulsion stabilizers for use in the formulations described herein include Tween® 60, Span® 80, cetostearyl alcohol, benzyl alcohol, myristyl alcohol, glyceryl monostearate, and sodium lauryl sulfate.
[0243] Aqueous suspensions containing the compounds described herein, or their stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts, may contain the active material in admixture with additives suitable for the manufacture of aqueous suspensions, such as suspending agents such as sodium carboxymethylcellulose, croscarmellose, povidone, methylcellulose, hydroxypropylmethylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth, and gum acacia, dispersing or wetting agents such as naturally occurring phosphatides (e.g., lecithin), condensation products of alkylene oxides with fatty acids (e.g., polyoxyethylene stearates), condensation products of ethylene oxide with long-chain aliphatic alcohols (e.g., heptadecaethyleneoxycetanol), and condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides (e.g., polyethylene sorbitan monooleate). The aqueous suspensions may also contain one or more preservatives, for example, ethyl or n-propyl p-hydroxybenzoate, one or more coloring agents, one or more flavoring agents, and one or more sweetening agents, such as sucrose or saccharin.
[0244] Pharmaceutical compositions of the compounds described herein, or their stereoisomers, atropisomers, tautomers, or pharmaceutically acceptable salts, may be in the form of sterile injectable preparations, such as sterile aqueous or oily injectable suspensions. These suspensions may be formulated using suitable dispersing or wetting agents and suspending agents, as described above. Sterile injectable preparations may also be prepared as sterile injectable solutions or suspensions in non-toxic parenterally acceptable diluents or solvents, such as solutions in 1,3-butanediol, or as lyophilized powders. Among the acceptable vehicles and solvents that may be used are water, Ringer's solution, and isotonic sodium chloride solution. Additionally, sterile, fixed oils are conventionally used as solvents or suspending media. For this purpose, any bland, fixed oil may be used, including synthetic monoglycerides or diglycerides. Additionally, fatty acids, such as oleic acid, may also be used in the preparation of injectables.
[0245] The amount of active ingredient that may be combined with carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. For example, a sustained-release formulation intended for oral administration to humans may contain approximately 1 to 1000 mg of active ingredient, compounded with an appropriate and convenient amount of carrier material, which may vary from about 5 to about 95% (weight:weight) of the total composition. Pharmaceutical compositions may be prepared to provide easily measurable amounts for administration. For example, an aqueous solution intended for intravenous infusion may contain about 3 to 500 μg of active ingredient per milliliter of solution to result in infusion of a suitable volume at a rate of about 30 mL / hour.
[0246] Formulations suitable for parenteral administration include aqueous and non-aqueous sterile injection solutions which may contain antioxidants, buffers, bacteriostats, and solutes which render the formulation isotonic with the blood of the intended recipient, and aqueous and non-aqueous sterile suspensions which may include suspending agents and thickening agents.
[0247] Formulations suitable for topical administration to the eye also include eye drops, wherein the active ingredient is dissolved or suspended in a suitable carrier, especially an aqueous solvent for the active ingredient. The active ingredient is preferably present in such formulations in a concentration of about 0.5 to 20% w / w, for example, about 0.5 to 10% w / w, for example, about 1.5% w / w.
[0248] Formulations suitable for topical administration in the mouth include lozenges comprising the active ingredient in a flavored base, usually sucrose and acacia or tragacanth; pastilles comprising the active ingredient in an inert base such as gelatin and glycerin or sucrose and acacia; and mouthwashes comprising the active ingredient in a suitable liquid carrier.
[0249] Formulations for rectal administration may be presented as a suppository with a suitable base comprising, for example, cocoa butter or a salicylate.
[0250] Formulations suitable for pulmonary or nasal administration have, for example, particle sizes in the range of 0.1 to 500 microns (in micron increments, such as 0.5, 1, 30 microns, 35 microns, etc., including particle sizes in the range of 0.1 to 500 microns), which are administered by rapid inhalation through the nostrils to reach the alveolar sacs, or by inhalation through the mouth. Suitable formulations include aqueous or oily solutions of the active ingredient. Formulations suitable for aerosol or dry powder administration may be prepared according to conventional methods and may be delivered together with other therapeutic agents, such as compounds previously used to treat or prevent the disorders described below.
[0251] Formulations suitable for vaginal administration may be presented as pessaries, tampons, creams, gels, pastes, foams, or spray formulations containing, in addition to the active ingredient, such carriers as are deemed appropriate.
[0252] The formulations may be packaged in unit-dose or multi-dose containers, for example, sealed ampoules and vials, and may be stored in a freeze-dried (lyophilized) condition requiring only the addition of a sterile liquid carrier, for example, water, for injection immediately prior to use. Extemporaneous injection solutions and suspensions are prepared from sterile powders, granules, and tablets of the kind described above. Preferred unit dosage formulations are those containing a daily dose or daily unit sub-dose, as herein above recited, of the active ingredient, or an appropriate fraction thereof.
[0253] In one embodiment, a compound or its stereoisomer, atropisomer, tautomer, or pharmaceutically acceptable salt is formulated as a prodrug.
