BACKGROUND

Apoptosis (programmed cell death) is a highly conserved cellular process that is required for embryonic development and normal tissue homeostasis (Ashkenazi A. et al., Nat. Rev. Drug Discov. 2017, 16, 273-284). Apoptotic-type cell death involves morphological changes such as condensation of the nucleus, DNA fragmentation as well as biochemical phenomena such as the activation of caspases which cause damage to key structural components of the cell, resulting in its disassembly and death. Regulation of the process of apoptosis is complex and involves the activation or repression of several intracellular signaling pathways (Cory S. et al., Nature Review Cancer 2002, 2, 647-656; Thomas L. W. et al., FEBS Lett. 2010, 584, 2981-2989; Adams J. M. et al., Oncogene 2007, 26, 1324-1337)


The Bcl-2 protein family, which includes both pro-apoptotic and anti-apoptotic members, plays a pivotal role in the regulation of the apoptosis process (Youle R. J. et al., Nat. Rev. Mol. Cell Biol. 2008, 9, 47-59; Kelly G. L. et al., Adv. Cancer Res. 2011, 111, 39-96). Bcl-2, Bcl-XL, Bcl-W, Mcl-1 and A1 are anti-apoptotic proteins and they share a common BH regions. In contrast, the pro-apoptotic family members are divided into two groups. The multi-region pro-apoptotic proteins, such as Bax, Bak and Bok, are conventionally thought to have BH1-3 regions, whereas the BH3-only proteins are proposed to share homology in the BH3 region only. Members of BH3-only proteins include Bad, Bim, Bid, Noxa, Puma, Bik/Blk, Bmf, Hrk/DP5, Beclin-1 and Mule (Xu G. et al., Bioorg. Med. Chem. 2017, 25, 5548-5556; Hardwick J. M. et al., Cell. 2009, 138, 404; Reed J. C., Cell Death Differ. 2018, 25, 3-6; Kang M. H. et al., Clin Cancer Res 2009, 15, 1126-1132). The pro-apoptotic members (such as BAX and BAK), upon activation, form a homo-oligomer in the outer mitochondrial membrane that leads to pore formation and the escape of mitochondrial contents, a step into triggering apoptosis. Antiapoptotic members of the Bcl-2 family (such as Bcl-2, Bel-XL, and Mcl-1) block the activity of BAX and BAK. In normal cells, this process is tightly regulated. Abnormal cells can dysregulate this process to avoid cell death. One of the ways that cancer cells can accomplish this is by upregulating the antiapoptotic members of the Bcl-2 family of proteins. Overexpression or up-regulation of the anti-apoptotic Bcl-2 family proteins enhance cancer cell survival and cause resistance to a variety of anticancer therapies.


Aberrant expression or function of the proteins responsible for apoptotic signaling contributes to numerous human pathologies including auto-immune diseases, neurodegeneration (such as Parkinson's disease, Alzheimer's disease and ischaemia), inflammatory diseases, viral infections and cancer (such as colon cancer, breast cancer, small-cell lung cancer, non-small-cell lung cancer, bladder cancer, ovarian cancer, prostate cancer, chronic lymphoid leukemia, lymphoma, myeloma, acute myeloid leukemia, pancreatic cancer, etc.) (Hanahan D. et al., Cell 2000, 100. 57-70). Herein, it is prospective to target key apoptosis regulators for cancer treatment (Kale J. et al., Cell Death Differ. 2018, 25, 65-80; Vogler M. et al., Cell Death Differ. 2009, 16, 360-367).


By overexpressing one or more of these pro-survival proteins, cancer cells can evade elimination by normal physiological processes and thus gain a survival advantage. Myeloid Cell Leukemia-1 (Mcl-1) is a member of the pro-survival Bcl-2 family of proteins. Mcl-1 has the distinct trait of being essential for embryonic development as well as the survival of all hematopoietic lineages and progenitor populations. Mcl-1 is one of the most common genetic aberrations in human cancer and is highly expressed in many tumor types. Mcl-1 overexpression in human cancers is associated with high tumor grade and poor survival (Beroukhim R. et al., Nature 2010, 463, 899-905). Mcl-1 overexpression prevents cancer cells from undergoing programmed cell death (apoptosis), allowing the cells to survive despite widespread genetic damage. Further, its amplification is associated with both intrinsic and acquired resistance to a wide variety of antitumorigenic agents including chemotherapeutic agents such as microtubule binding agents, paclitaxel and gemcitabine, as well as apoptosis-inducing agents such as TRAIL, the Bcl-2 inhibitor, venetoclax, and the Bcl-2/Bcl-XL dual inhibitor navitoclax. Not only do gene silencing approaches that specifically target Mcl-1 circumvent this resistance phenotype, but certain cancer cell types frequently undergo cell death in response to Mcl-1 silencing, indicating a dependence on Mcl-1 for survival. Consequently, approaches that inhibit Mcl-1 function are of considerable interest for cancer therapy (Wertz I. E et al., Nature 2011, 471, 110-114; Zhang B. et al., Blood 2002, 99, 1885-1893).

An exemplary dosage is 10 to 30 mg per day. The exact dosage will depend upon the route of administration, the form in which the compound is administered, the subject to be treated, the body weight of the subject to be treated, and the preference and experience of the attending physician.


A pharmaceutical composition of the invention typically contains an active ingredient (i.e., a compound of the disclosure) of the present invention or a pharmaceutically acceptable salt and/or coordination complex thereof, and one or more pharmaceutically acceptable excipients, carriers, including but not limited to inert solid diluents and fillers, diluents, sterile aqueous solution and various organic solvents, permeation enhancers, solubilizers and adjuvants.


Described below are non-limiting exemplary pharmaceutical compositions and methods for preparing the same.


Pharmaceutical Compositions for Oral Administration.

In some embodiments, the invention provides a pharmaceutical composition for oral administration containing a compound of the invention, and a pharmaceutical excipient suitable for oral administration.


In some embodiments, the invention provides a solid pharmaceutical composition for oral administration containing: (i) an effective amount of a compound of the invention; optionally (ii) an effective amount of a second agent; and (iii) a pharmaceutical excipient suitable for oral administration. In some embodiments, the composition further contains: (iv) an effective amount of a third agent.


In some embodiments, the pharmaceutical composition may be a liquid pharmaceutical composition suitable for oral consumption. Pharmaceutical compositions of the invention suitable for oral administration can be presented as discrete dosage forms, such as capsules, cachets, or tablets, or liquids or aerosol sprays each containing a predetermined amount of an active ingredient as a powder or in granules, a solution, or a suspension in an aqueous or non-aqueous liquid, an oil-in-water emulsion, or a water-in-oil liquid emulsion. Such dosage forms can be prepared by any of the methods of pharmacy, but all methods include the step of bringing the active ingredient into association with the carrier, which constitutes one or more necessary ingredients. In general, the compositions are prepared by uniformly and intimately admixing the active ingredient with liquid carriers or finely divided solid carriers or both, and then, if necessary, shaping the product into the desired presentation. For example, a tablet can be prepared by compression or molding, optionally with one or more accessory ingredients. Compressed tablets can be prepared by compressing in a suitable machine the active ingredient in a free-flowing form such as powder or granules, optionally mixed with an excipient such as, but not limited to, a binder, a lubricant, an inert diluent, and/or a surface active or dispersing agent. Molded tablets can be made by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent.


This invention further encompasses anhydrous pharmaceutical compositions and dosage forms comprising an active ingredient, since water can facilitate the degradation of some compounds. For example, water may be added (e.g., 5%) in the pharmaceutical arts as a means of simulating long-term storage in order to determine characteristics such as shelf-life or the stability of formulations over time. Anhydrous pharmaceutical compositions and dosage forms of the invention can be prepared using anhydrous or low moisture containing ingredients and low moisture or low humidity conditions. Pharmaceutical compositions and dosage forms of the invention which contain lactose can be made anhydrous if substantial contact with moisture and/or humidity during manufacturing, packaging, and/or storage is expected. An anhydrous pharmaceutical composition may be prepared and stored such that its anhydrous nature is maintained. Accordingly, anhydrous compositions may be packaged using materials known to prevent exposure to water such that they can be included in suitable formulary kits. Examples of suitable packaging include, but are not limited to, hermetically sealed foils, plastic or the like, unit dose containers, blister packs, and strip packs.


An active ingredient can be combined in an intimate admixture with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques. The carrier can take a wide variety of forms depending on the form of preparation desired for administration. In preparing the compositions for an oral dosage form, any of the usual pharmaceutical media can be employed as carriers, such as, for example, water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents, and the like in the case of oral liquid preparations (such as suspensions, solutions, and elixirs) or aerosols; or carriers such as starches, sugars, micro-crystalline cellulose, diluents, granulating agents, lubricants, binders, and disintegrating agents can be used in the case of oral solid preparations, in some embodiments without employing the use of lactose. For example, suitable carriers include powders, capsules, and tablets, with the solid oral preparations. If desired, tablets can be coated by standard aqueous or nonaqueous techniques.


Binders suitable for use in pharmaceutical compositions and dosage forms include, but are not limited to, corn starch, potato starch, or other starches, gelatin, natural and synthetic gums such as acacia, sodium alginate, alginic acid, other alginates, powdered tragacanth, guar gum, cellulose and its derivatives (e.g., ethyl cellulose, cellulose acetate, carboxymethyl cellulose calcium, sodium carboxymethyl cellulose), polyvinyl pyrrolidone, methyl cellulose, pre-gelatinized starch, hydroxypropyl methyl cellulose, microcrystalline cellulose, and mixtures thereof.


Examples of suitable fillers for use in the pharmaceutical compositions and dosage forms disclosed herein include, but are not limited to, talc, calcium carbonate (e.g., granules or powder), microcrystalline cellulose, powdered cellulose, dextrates, kaolin, mannitol, silicic acid, sorbitol, starch, pre-gelatinized starch, and mixtures thereof.


Disintegrants may be used in the compositions of the invention to provide tablets that disintegrate when exposed to an aqueous environment. Too much of a disintegrant may produce tablets which may disintegrate in the bottle. Too little may be insufficient for disintegration to occur and may thus alter the rate and extent of release of the active ingredient(s) from the dosage form. Thus, a sufficient amount of disintegrant that is neither too little nor too much to detrimentally alter the release of the active ingredient(s) may be used to form the dosage forms of the compounds disclosed herein. The amount of disintegrant used may vary based upon the type of formulation and mode of administration, and may be readily discernible to those of ordinary skill in the art. About 0.5 to about 15 weight percent of disintegrant, or about 1 to about 5 weight percent of disintegrant, may be used in the pharmaceutical composition. Disintegrants that can be used to form pharmaceutical compositions and dosage forms of the invention include, but are not limited to, agar-agar, alginic acid, calcium carbonate, microcrystalline cellulose, croscarmellose sodium, crospovidone, polacrilin potassium, sodium starch glycolate, potato or tapioca starch, other starches, pre-gelatinized starch, other starches, clays, other algins, other celluloses, gums or mixtures thereof.


Lubricants which can be used to form pharmaceutical compositions and dosage forms of the invention include, but are not limited to, calcium stearate, magnesium stearate, mineral oil, light mineral oil, glycerin, sorbitol, mannitol, polyethylene glycol, other glycols, stearic acid, sodium lauryl sulfate, talc, hydrogenated vegetable oil (e.g., peanut oil, cottonseed oil, sunflower oil, sesame oil, olive oil, corn oil, and soybean oil), zinc stearate, ethyl oleate, ethyl laureate, agar, or mixtures thereof. Additional lubricants include, for example, a syloid silica gel, a coagulated aerosol of synthetic silica, or mixtures thereof. A lubricant can optionally be added, in an amount of less than about 1 weight percent of the pharmaceutical composition.


When aqueous suspensions and/or elixirs are desired for oral administration, the active ingredient therein may be combined with various sweetening or flavoring agents, coloring matter or dyes and, if so desired, emulsifying and/or suspending agents, together with such diluents as water, ethanol, propylene glycol, glycerin and various combinations thereof.


The tablets can be uncoated or coated by known techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate can be employed. Formulations for oral use can also be presented as hard gelatin capsules wherein the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, for example, peanut oil, liquid paraffin or olive oil.


Surfactant which can be used to form pharmaceutical compositions and dosage forms of the invention include, but are not limited to, hydrophilic surfactants, lipophilic surfactants, and mixtures thereof. That is, a mixture of hydrophilic surfactants may be employed, a mixture of lipophilic surfactants may be employed, or a mixture of at least one hydrophilic surfactant and at least one lipophilic surfactant may be employed.


A suitable hydrophilic surfactant may generally have an HLB value of at least 10, while suitable lipophilic surfactants may generally have an HLB value of or less than about 10. An empirical parameter used to characterize the relative hydrophilicity and hydrophobicity of non-ionic amphiphilic compounds is the hydrophilic-lipophilic balance (“HLB” value). Surfactants with lower HLB values are more lipophilic or hydrophobic, and have greater solubility in oils, while surfactants with higher HLB values are more hydrophilic, and have greater solubility in aqueous solutions.


Hydrophilic surfactants are generally considered to be those compounds having an HLB value greater than about 10, as well as anionic, cationic, or zwitterionic compounds for which the HLB scale is not generally applicable. Similarly, lipophilic (i.e., hydrophobic) surfactants are compounds having an HLB value equal to or less than about 10. However, HLB value of a surfactant is merely a rough guide generally used to enable formulation of industrial, pharmaceutical and cosmetic emulsions.


Hydrophilic surfactants may be either ionic or non-ionic. Suitable ionic surfactants include, but are not limited to, alkylammonium salts; fusidic acid salts; fatty acid derivatives of amino acids, oligopeptides, and polypeptides; glyceride derivatives of amino acids, oligopeptides, and polypeptides; lecithins and hydrogenated lecithins; lysolecithins and hydrogenated lysolecithins; phospholipids and derivatives thereof; lysophospholipids and derivatives thereof; carnitine fatty acid ester salts; salts of alkylsulfates; fatty acid salts; sodium docusate; acyl lactylates; mono- and di-acetylated tartaric acid esters of mono- and di-glycerides; succinylated mono- and di-glycerides; citric acid esters of mono- and di-glycerides; and mixtures thereof.

In one embodiment, the composition may include a solubilizer to ensure good solubilization and/or dissolution of the compound of the present invention and to minimize precipitation of the compound of the present invention. This can be especially important for compositions for non-oral use, e.g., compositions for injection. A solubilizer may also be added to increase the solubility of the hydrophilic drug and/or other components, such as surfactants, or to maintain the composition as a stable or homogeneous solution or dispersion.


Examples of suitable solubilizers include, but are not limited to, the following: alcohols and polyols, such as ethanol, isopropanol, butanol, benzyl alcohol, ethylene glycol, propylene glycol, butanediols and isomers thereof, glycerol, pentaerythritol, sorbitol, mannitol, transcutol, dimethyl isosorbide, polyethylene glycol, polypropylene glycol, polyvinylalcohol, hydroxypropyl methylcellulose and other cellulose derivatives, cyclodextrins and cyclodextrin derivatives; ethers of polyethylene glycols having an average molecular weight of about 200 to about 6000, such as tetrahydrofurfuryl alcohol PEG ether (glycofurol) or methoxy PEG; amides and other nitrogen-containing compounds such as 2-pyrrolidone, 2-piperidone, ε-caprolactam, N-alkylpyrrolidone, N-hydroxyalkylpyrrolidone, N-alkylpiperidone, N-alkylcaprolactam, dimethylacetamide and polyvinylpyrrolidone; esters such as ethyl propionate, tributylcitrate, acetyl triethylcitrate, acetyl tributyl citrate, triethylcitrate, ethyl oleate, ethyl caprylate, ethyl butyrate, triacetin, propylene glycol monoacetate, propylene glycol diacetate, ε-caprolactone and isomers thereof, δ-valerolactone and isomers thereof, β-butyrolactone and isomers thereof; and other solubilizers known in the art, such as dimethyl acetamide, dimethyl isosorbide, N-methyl pyrrolidones, monooctanoin, diethylene glycol monoethyl ether, and water.

The amount of solubilizer that can be included is not particularly limited. The amount of a given solubilizer may be limited to a bioacceptable amount, which may be readily determined by one of skill in the art. In some circumstances, it may be advantageous to include amounts of solubilizers far in excess of bioacceptable amounts, for example to maximize the concentration of the drug, with excess solubilizer removed prior to providing the composition to a subject using conventional techniques, such as distillation or evaporation. Thus, if present, the solubilizer can be in a weight ratio of 10%, 25%, 50%), 100%, or up to about 200%> by weight, based on the combined weight of the drug, and other excipients. If desired, very small amounts of solubilizer may also be used, such as 5%>, 2%>, 1%) or even less. Typically, the solubilizer may be present in an amount of about 1%> to about 100%, more typically about 5%> to about 25%> by weight.


The composition can further include one or more pharmaceutically acceptable additives and excipients. Such additives and excipients include, without limitation, detackifiers, anti-foaming agents, buffering agents, polymers, antioxidants, preservatives, chelating agents, viscomodulators, tonicifiers, flavorants, colorants, odorants, opacifiers, suspending agents, binders, fillers, plasticizers, lubricants, and mixtures thereof.


In addition, an acid or a base may be incorporated into the composition to facilitate processing, to enhance stability, or for other reasons. Examples of pharmaceutically acceptable bases include amino acids, amino acid esters, ammonium hydroxide, potassium hydroxide, sodium hydroxide, sodium hydrogen carbonate, aluminum hydroxide, calcium carbonate, magnesium hydroxide, magnesium aluminum silicate, synthetic aluminum silicate, synthetic hydrocalcite, magnesium aluminum hydroxide, diisopropylethylamine, ethanolamine, ethylenediamine, triethanolamine, triethylamine, triisopropanolamine, trimethylamine, tris(hydroxymethyl)aminomethane (TRIS) and the like.

Salts of polyprotic acids, such as sodium phosphate, disodium hydrogen phosphate, and sodium dihydrogen phosphate can also be used. When the base is a salt, the cation can be any convenient and pharmaceutically acceptable cation, such as ammonium, alkali metals, alkaline earth metals, and the like. Example may include, but not limited to, sodium, potassium, lithium, magnesium, calcium and ammonium.

Pharmaceutical Compositions for Injection.

In some embodiments, the invention provides a pharmaceutical composition for injection containing a compound of the present invention and a pharmaceutical excipient suitable for injection. Components and amounts of agents in the compositions are as described herein.


The forms in which the novel compositions of the present invention may be incorporated for administration by injection include aqueous or oil suspensions, or emulsions, with sesame oil, corn oil, cottonseed oil, or peanut oil, as well as elixirs, mannitol, dextrose, or a sterile aqueous solution, and similar pharmaceutical vehicles.


Aqueous solutions in saline are also conventionally used for injection. Ethanol, glycerol, propylene glycol, liquid polyethylene glycol, and the like (and suitable mixtures thereof), cyclodextrin derivatives, and vegetable oils may also be employed. The proper fluidity can be maintained, for example, by the use of a coating, such as lecithin, for the maintenance of the required particle size in the case of dispersion and by the use of surfactants. The prevention of the action of microorganisms can be brought about by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like.


Sterile injectable solutions are prepared by incorporating the compound of the present invention in the required amount in the appropriate solvent with various other ingredients as enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the various sterilized active ingredients into a sterile vehicle which contains the basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, certain desirable methods of preparation are vacuum-drying and freeze-drying techniques which yield a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof.


Pharmaceutical Compositions for Topical (e.g. Transdermal) Delivery.


In some embodiments, the invention provides a pharmaceutical composition for transdermal delivery containing a compound of the present invention and a pharmaceutical excipient suitable for transdermal delivery.


Compositions of the present invention can be formulated into preparations in solid, semisolid, or liquid forms suitable for local or topical administration, such as gels, water soluble jellies, creams, lotions, suspensions, foams, powders, slurries, ointments, solutions, oils, pastes, suppositories, sprays, emulsions, saline solutions, dimethylsulfoxide (DMSO)-based solutions. In general, carriers with higher densities are capable of providing an area with a prolonged exposure to the active ingredients. In contrast, a solution formulation may provide more immediate exposure of the active ingredient to the chosen area.


The pharmaceutical compositions also may comprise suitable solid or gel phase carriers or excipients, which are compounds that allow increased penetration of, or assist in the delivery of, therapeutic molecules across the stratum corneum permeability barrier of the skin. There are many of these penetration-enhancing molecules known to those trained in the art of topical formulation.


Examples of such carriers and excipients include, but are not limited to, humectants (e.g., urea), glycols (e.g., propylene glycol), alcohols (e.g., ethanol), fatty acids (e.g., oleic acid), surfactants (e.g., isopropyl myristate and sodium lauryl sulfate), pyrrolidones, glycerol monolaurate, sulfoxides, terpenes (e.g., menthol), amines, amides, alkanes, alkanols, water, calcium carbonate, calcium phosphate, various sugars, starches, cellulose derivatives, gelatin, and polymers such as polyethylene glycols.


Another exemplary formulation for use in the methods of the present invention employs transdermal delivery devices (“patches”). Such transdermal patches may be used to provide continuous or discontinuous infusion of a compound of the present invention in controlled amounts, either with or without another agent.


The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art. See, e.g., U.S. Pat. Nos. 5,023,252, 4,992,445 and 5,001,139. Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents.


Pharmaceutical Compositions for Inhalation.

Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. Preferably the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions in preferably pharmaceutically acceptable solvents may be nebulized by use of inert gases. Nebulized solutions may be inhaled directly from the nebulizing device or the nebulizing device may be attached to a face mask tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions may be administered, preferably orally or nasally, from devices that deliver the formulation in an appropriate manner.


Other Pharmaceutical Compositions.

Pharmaceutical compositions may also be prepared from compositions described herein and one or more pharmaceutically acceptable excipients suitable for sublingual, buccal, rectal, intraosseous, intraocular, intranasal, epidural, or intraspinal administration. Preparations for such pharmaceutical compositions are well-known in the art. See, e.g., 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, N.Y., 1990; Katzung, ed., Basic and Clinical Pharmacology, Ninth Edition, McGraw Hill, 20037ybg; Goodman and Gilman, eds., The Pharmacological Basis of Therapeutics, Tenth Edition, McGraw Hill, 2001; Remingtons Pharmaceutical Sciences, 20th Ed., Lippincott Williams & Wilkins., 2000; Martindale, The Extra Pharmacopoeia, Thirty-Second Edition (The Pharmaceutical Press, London, 1999); all of which are incorporated by reference herein in their entirety.


Administration of the compounds or pharmaceutical composition of the present invention can be effected by any method that enables delivery of the compounds to the site of action. These methods include oral routes, intraduodenal routes, parenteral injection (including intravenous, intraarterial, subcutaneous, intramuscular, intravascular, intraperitoneal or infusion), topical (e.g. transdermal application), rectal administration, via local delivery by catheter or stent or through inhalation. Compounds can also be administered intraadiposally or intrathecally.


In some embodiments, the compounds or pharmaceutical composition of the present invention are administered by intravenous injection.


The amount of the compound administered will be dependent on the subject being treated, the severity of the disorder or condition, the rate of administration, the disposition of the compound and the discretion of the prescribing physician. However, an effective dosage is in the range of about 0.001 to about 100 mg per kg body weight per day, preferably about 1 to about 35 mg/kg/day, in single or divided doses. For a 70 kg human, this would amount to about 0.05 to 7 g/day, preferably about 0.05 to about 2.5 g/day. In some instances, dosage levels below the lower limit of the aforesaid range may be more than adequate, while in other cases still larger doses may be employed without causing any harmful side effect, e.g. by dividing such larger doses into several small doses for administration throughout the day.


In some embodiments, a compound of the invention is administered in a single dose.


Typically, such administration will be by injection, e.g., intravenous injection, in order to introduce the agent quickly. However, other routes may be used as appropriate. A single dose of a compound of the invention may also be used for treatment of an acute condition.


In some embodiments, a compound of the invention is administered in multiple doses. Dosing may be about once, twice, three times, four times, five times, six times, or more than six times per day. Dosing may be about once a month, once every two weeks, once a week, or once every other day. In another embodiment a compound of the invention and another agent are administered together about once per day to about 6 times per day. In another embodiment the administration of a compound of the invention and an agent continues for less than about 7 days. In yet another embodiment the administration continues for more than about 6, 10, 14, 28 days, two months, six months, or one year. In some cases, continuous dosing is achieved and maintained as long as necessary.


Administration of the compounds of the invention may continue as long as necessary. In some embodiments, a compound of the invention is administered for more than 1, 2, 3, 4, 5, 6, 7, 14, or 28 days. In some embodiments, a compound of the invention is administered for less than 28, 14, 7, 6, 5, 4, 3, 2, or 1 day. In some embodiments, a compound of the invention is administered chronically on an ongoing basis, e.g., for the treatment of chronic effects.


An effective amount of a compound of the invention may be administered in either single or multiple doses by any of the accepted modes of administration of agents having similar utilities, including rectal, buccal, intranasal and transdermal routes, by intra-arterial injection, intravenously, intraperitoneally, parenterally, intramuscularly, subcutaneously, orally, topically, or as an inhalant.


The compositions of the invention may also be delivered via an impregnated or coated device such as a stent, for example, or an artery-inserted cylindrical polymer. Such a method of administration may, for example, aid in the prevention or amelioration of restenosis following procedures such as balloon angioplasty. Without being bound by theory, compounds of the invention may slow or inhibit the migration and proliferation of smooth muscle cells in the arterial wall which contribute to restenosis. A compound of the invention may be administered, for example, by local delivery from the struts of a stent, from a stent graft, from grafts, or from the cover or sheath of a stent. In some embodiments, a compound of the invention is admixed with a matrix. Such a matrix may be a polymeric matrix, and may serve to bond the compound to the stent. Polymeric matrices suitable for such use, include, for example, lactone-based polyesters or copolyesters such as polylactide, polycaprolactonglycolide, polyorthoesters, polyanhydrides, polyaminoacids, polysaccharides, polyphosphazenes, poly (ether-ester) copolymers (e.g. PEO-PLLA); polydimethylsiloxane, poly(ethylene-vinylacetate), acrylate-based polymers or copolymers (e.g. polyhydroxyethyl methylmethacrylate, polyvinyl pyrrolidinone), fluorinated polymers such as polytetrafluoroethylene and cellulose esters. Suitable matrices may be nondegrading or may degrade with time, releasing the compound or compounds. Compounds of the invention may be applied to the surface of the stent by various methods such as dip/spin coating, spray coating, dip-coating, and/or brush-coating. The compounds may be applied in a solvent and the solvent may be allowed to evaporate, thus forming a layer of compound onto the stent. Alternatively, the compound may be located in the body of the stent or graft, for example in microchannels or micropores. When implanted, the compound diffuses out of the body of the stent to contact the arterial wall. Such stents may be prepared by dipping a stent manufactured to contain such micropores or microchannels into a solution of the compound of the invention in a suitable solvent, followed by evaporation of the solvent. Excess drug on the surface of the stent may be removed via an additional brief solvent wash. In yet other embodiments, compounds of the invention may be covalently linked to a stent or graft. A covalent linker may be used which degrades in vivo, leading to the release of the compound of the invention. Any bio-labile linkage may be used for such a purpose, such as ester, amide or anhydride linkages. Compounds of the invention may additionally be administered intravascularly from a balloon used during angioplasty. Extravascular administration of the compounds via the pericard or via advential application of formulations of the invention may also be performed to decrease restenosis.


A variety of stent devices which may be used as described are disclosed, for example, in the following references, all of which are hereby incorporated by reference: U.S. Pat. Nos. 5,451,233; 5,040,548; 5,061,273; 5,496,346; 5,292,331; 5,674,278; 3,657,744; 4,739,762; 5,195,984; 5,292,331; U.S. Pat. Nos. 5,674,278; 5,879,382; 6,344,053.


The compounds of the invention may be administered in dosages. It is known in the art that due to intersubject variability in compound pharmacokinetics, individualization of dosing regimen is necessary for optimal therapy. Dosing for a compound of the invention may be found by routine experimentation in light of the instant disclosure.


When a compound of the invention is administered in a composition that comprises one or more agents, and the agent has a shorter half-life than the compound of the invention unit dose forms of the agent and the compound of the invention may be adjusted accordingly.


The subject pharmaceutical composition may, for example, be in a form suitable for oral administration as a tablet, capsule, pill, powder, sustained release formulations, solution, suspension, for parenteral injection as a sterile solution, suspension or emulsion, for topical administration as an ointment or cream or for rectal administration as a suppository. The pharmaceutical composition may be in unit dosage forms suitable for single administration of precise dosages. The pharmaceutical composition will include a conventional pharmaceutical carrier or excipient and a compound according to the invention as an active ingredient. In addition, it may include other medicinal or pharmaceutical agents, carriers, adjuvants, etc.


Exemplary parenteral administration forms include solutions or suspensions of active compound in sterile aqueous solutions, for example, aqueous propylene glycol or dextrose solutions. Such dosage forms can be suitably buffered, if desired.


Methods of Use

The method typically comprises administering to a subject a therapeutically effective amount of a compound of the invention. The therapeutically effective amount of the subject combination of compounds may vary depending upon the intended application (in vitro or in vivo), or the subject and disease condition being treated, e.g., the weight and age of the subject, the severity of the disease condition, the manner of administration and the like, which can readily be determined by one of ordinary skill in the art. The term also applies to a dose that will induce a particular response in target cells, e.g., reduction of proliferation or downregulation of activity of a target protein. The specific dose will vary depending on the particular compounds chosen, the dosing regimen to be followed, whether it is administered in combination with other compounds, timing of administration, the tissue to which it is administered, and the physical delivery system in which it is carried.


As used herein, the term “IC50” refers to the half maximal inhibitory concentration of an inhibitor in inhibiting biological or biochemical function. This quantitative measure indicates how much of a particular inhibitor is needed to inhibit a given biological process (or component of a process, i.e. an enzyme, cell, cell receptor or microorganism) by half. In other words, it is the half maximal (50%) inhibitory concentration (IC) of a substance (50% IC, or IC50). EC50 refers to the plasma concentration required for obtaining 50%> of a maximum effect in vivo.

Step 1: N-methoxy-N-methyl-carbamoyl chloride

To a solution of N,O-dimethylhydroxylamine hydrochloride (500 mg, 8.19 mmol) in DCM (10 mL) was added triphosgene (2429 mg, 8.19 mmol), followed by potassium carbonate (4525 mg, 32.7 mmol). The mixture was stirred at r.t. for 1 h. NMR showed that the starting material was consumed. The reaction was then added H2O (15 mL) and extracted with DCM (10 mL×3). The combined organic layers were dried over Na2SO4, filtered and concentrated under reduced pressure. The resulting residue N-methoxy-N-methyl-carbamoyl chloride (600 mg, 59% yield) was directly used in the following step without further purification.

A suspension of lithium aluminium deuteride (2.0 g, 46.5 mmol) in ether (20 mL) was cooled at −78° C. under N2. 2-Propenoyl chloride (4.0 mL, 39.44 mmol) in ether (20 mL) was added dropwise over 1 h. at −78° C. The mixture was then allowed to slowly warm to r.t. and stirred overnight. The mixture was carefully quenched at −10° C. with water (4 mL), followed by 15% NaOH (4 mL). The mixture was diluted with water (12 mL), and stirred for 1 h. The mixture was filtered. The filtrate was dried over Na2SO4, filtered and the solvent was partially removed under reduced pressure. The crude product (0.25 g, 4.19 mmol) and 2-bromo-2-methyl-propanoic acid (1.0 g, 5.99 mmol) was dissolved in MeCN (3 mL). DIPEA (2.3 g, 18 mmol) was added and the mixture was stirred at 50° C. overnight. The mixture was quenched with 1 M HCl (20 mL) and extracted with EtOAc (20 mL×2). The organic layer was concentrated. The residue was purified with flash chromatography on a silica gel column with EtOAc:Heptane (0% to 40%) to afford 2-(1,1-dideuterioallyloxy)-2-methyl-propanoic acid (500 mg, 40.% yield).

Single-Crystal X-ray Analysis of Example 34



embedded image


A saturated solution of Example 34 in ethanol/methyl tert-butyl ether (4/1) was stored at 23-25° C., and after 4 days, cubic crystals were observed. A crystal of approximate dimensions 0.197 mm×0.250 mm×0.345 mm, was used for the X-ray crystallographic analysis. The X-ray intensity data were measured.


The total exposure time was 3.45 hours. The frames were integrated with the Bruker SAINT software package using a narrow-frame algorithm. The integration of the data using an orthorhombic unit cell yielded a total of 26210 reflections to a maximum θ angle of 75.55° (0.80 Å resolution), of which 8525 were independent (average redundancy 3.074, completeness=98.9%, Rint=4.77%, Rsig=4.89%) and 7840 (91.96%) were greater than 2σ(F2). The final cell constants of a=9.1529(13) Å, b=11.1812(17) Å, c=41.054(7) Å, volume=4201.5(11) Å3, are based upon the refinement of the XYZ-centroids of 9678 reflections above 20 σ(I) with 6.4630<2θ<150.8°. Data were corrected for absorption effects using the Multi-Scan method (SADAB S). The ratio of minimum to maximum apparent transmission was 0.838. The calculated minimum and maximum transmission coefficients (based on crystal size) are 0.5830 and 0.7240.



FIG. 1 shows an ORTEP representation of the compound of Example 34. The structure was solved and refined using the Bruker SHELXTL Software Package, using the space group P 21 21 21, with Z=4 for the formula unit, C40H60ClN3O10S. The final anisotropic full-matrix least-squares refinement on F2 with 504 variables converged at R1=7.06%, for the observed data and wR2=20.53% for all data. The goodness-of-fit was 1.151. The largest peak in the final difference electron density synthesis was 0.445 e/Å3 and the largest hole was −0.447 e/Å3 with an RMS deviation of 0.091 e/Å3. On the basis of the final model, the calculated density was 1.281 g/cm3 and F (000), 1736 e.

The binding affinity of each compound was measured via a fluorescence polarization competition assay, in which the compound competes for the same binding site with the ligand, and thus leads to a dose-dependent anisotropy reduction. The tracer ligand utilized was a fluorescein isothiocyanate labelled peptide (FITC-ARIAQELRRIGDEFNETYTR) derived from Bim (GenScript).


The assay was carried out in black half-area 96-well NBS plate (Corning), containing 15 nM of MCL-1 (BPS Bioscience), 5 nM of FITC-Bim and 3-fold serial diluted test compounds in a total volume of 50 μL of assay buffer (20 mM HEPES, 50 mM NaCl, 0.002% Tween 20, 1 mM TCEP, and 1% DMSO). The reaction plate was incubated for 1 hour at room temperature. The change of anisotropy is measured with an Envision multimode plate reader (PerkinElmer) at emission wavelength 535 nm. Fluorescence polarization was calculated in mP unit and the percentage inhibition was calculated by % inhibition=100×(mPDMSO−mP)/(mPDMSO−mPPC), in which mPDMSO is the DMSO control, and mPpc is the positive control. IC50 values were determined from a 10-point dose response curve by fitting the percent inhibition against compound concentration using the GraphPad Prism software. The inhibition constant Ki was subsequently calculated according to the Nikolovska-Coleska's equation (Anal. Biochem., 2004, 332, 261),

Cytotoxicity Studies in NCI-H929 Cells

Cytotoxicity studies were conducted in NCI-H929 multiple myeloma cell line. Cells were maintained in RPMI 1640 (Corning Cellgro, Catalog #: 10-040-CV) supplemented with 10% v/v FBS (GE Healthcare, Catalog #: SH30910.03), 10 mM HEPES (Corning, Catalog #: 25-060-CI), 1 mM sodium pyruvate (Corning Cellgro, Catalog #: 25-000-CI and 2500 mg/L glucose (Gibco, Catalog #: A24940-01). Cells were seeded in 96-well plates at a density of 75000 cells/well. Compounds dissolved in DMSO were plated in duplicate using a digital dispenser (Tecan D300E) and tested on a 9-point 3-fold serial dilution. Cells were incubated for 24 hr in a 37° C. incubator at 5% CO2. Cell viability was measured using the Cell Counting Kit-8 (CCK-8, Jojindo, CK04-13) as per manufacturer's instructions. Cells were incubated for 4 hours at 37° C. 5% CO2 following addition of reagent and OD450 values were measured with a microplate reader (iMark microplate reader, Bio-Rad). Background from media only wells were averaged and subtracted from all readings. OD450 values were then normalized to DMSO controls to obtain percentage of viable cells, relative to DMSO vehicle control and plotted in Graphpad Prism ([Inhibitor] vs. normalized response−Variable slope; equation: Y=100/(1+(X{circumflex over ( )}HillSlope)/(IC50{circumflex over ( )}HillSlope))) to determine ICso values (the concentration of compound inhibiting half of the maximal activity).
