FIELD OF THE INVENTION
The present invention is directed to novel 3-pyrimidinyl-4-yl-oxazolidin-2-one compounds, compositions containing these compounds, the use of such compounds in the inhibition of mutant IDH proteins having a neomorphic activity and in the treatment of diseases or disorders associated with such mutant IDH proteins including, but not limited to, cell-proliferation disorders, such as cancer.
BACKGROUND OF THE INVENTION
Isocitrate dehydrogenase (IDH) is a key family of enzymes found in cellular metabolism. They are NADP+/NAD+ and metal dependent oxidoreductases of the enzyme class EC 1.1.1.42. The wild type proteins catalyze the oxidative decarboxylation of isocitrate to alpha-ketoglutarate generating carbon dioxide and NADPH/NADH in the process. They are also known to convert oxalosuccinate into alpha-ketoglutarate. Mutations in IDH1 (cytosolic) and IDH2 (mitochondrial) have been identified in multiple cancer types including, but not limited to, glioma, glioblastoma multiforme, paraganglioma, supratentorial primordial neuroectodermal tumors, acute myeloid leukemia (AML), prostate cancer, thyroid cancer, colon cancer, chondrosarcoma, cholangiocarcinoma, peripheral T-cell lymphoma, and melanoma. (See L. Dang et al., Trends Mol. Med., 2010, 16, 387; T. Shibata et al., Am. J. Pathol., 2011, 178(3), 1395; Gaal et al., J. Clin. Endocrinol. Metab. 2010; Hayden et al., Cell Cycle, 2009; Balss et al., Acta Neuropathol., 2008). The mutations have been found at or near key residues in the active site: G97D, R100, R132, H133Q, and A134D for IDH1, and R140 and R172 for IDH2. (See L. Dang et al., Nature, 2009, 462, 739; L. Sellner et al., Eur. J. Haematol., 2011, 85, 457).
These mutant forms of IDH are shown to have a neomorphic activity (also known as a gain of function activity), reducing alpha-ketoglutarate to 2-hydroxyglutarate (2-HG). (See P. S. Ward et al., Cancer Cell, 2010, 17, 225) In general, production of 2-HG is enantiospecific, resulting in generation of the D-enantiomer (also known as R enantiomer or R-2-HG). Normal cells have low native levels of 2-HG, whereas cells harboring these mutations in IDH1 or IDH2 show significantly elevated levels of 2-HG. High levels of 2-HG have been detected in tumors harboring the mutations. For example, high levels of 2-HG have been detected in the plasma of patients with mutant IDH containing AML. (See S. Gross et al., J. Exp. Med., 2010, 207(2), 339). High levels of 2-HG are highly associated with tumorigenesis.
Mutant IDH2 is also associated with the rare neurometabolic disorder D-2-hydroxyglutaric aciduria type II (D-2-HGA type II). Germline mutations were found at R140 in IDH2 in 15 pateints having D-2-HGA type II. Patients having this disorder also have consistently increased levels of D-2-HG in their urine, plasma and cerebrospinal fluid. (See Kranendijk, M. et al., Science, 2010, 330, 336). Finally, patients with Ollier Disease and Mafucci Syndrome (two rare disorders that predispose to cartilaginous tumors) have been shown to be somatically mosaic for IDH1 and 2 mutations and exhibit high levels of D-2-HG. (See Amary et al., Nature Genetics, 2011 and Pansuriya et al., Nature Genetics, 2011).
Thus, there is a need for small molecule inhibitors of mutant IDH proteins having a neomorphic activity for the treatment of diseases and disorders associated with these proteins.

“Pharmaceutically acceptable” means a compound which is suitable for pharmaceutical use. Salts and solvates (e.g. hydrates and hydrates of salts) of compounds of the invention which are suitable for use in medicine are those where in the counterion or associated solvent is pharmaceutically acceptable. However, salts and solvates having non-pharmaceutically acceptable counterions or associated solvents are within the scope of the present invention, for example, for use as intermediates in the preparation of other compounds of the invention and their pharmaceutically acceptable salts and solvates.
“Substituted” in reference to a group such as alkyl, phenyl, benzyl, heteroaryl, and heterocyclic, indicates that one or more hydrogen atoms attached to an atom within the group is replaced with a substituent selected from the group of defined substituents. It should be understood that the term “substituted” includes the implicit provision that such substitution be in accordance with permitted valence of the substituted atom and the substituent, and that the substitution results in a stable compound (i.e. one that does not spontaneously undergo transformation, for example, by hydrolysis, rearrangement, cyclization, or elimination and that is sufficiently robust to survive isolation from a reaction mixture). When it is stated that a group may contain one or more substituents, one or more (as appropriate) atoms within the group may be substituted. In addition, a single atom within the group may be substituted with more than one substituent as long as such substitution is accordance with the permitted valence of the atom. Suitable substituents are defined for each substituted or optionally substituted group.
The skilled artisan will appreciate that salts, including pharmaceutically acceptable salts, of the compounds according to formula (I) may be prepared. These salts may be prepared in situ during the final isolation and purification of the compound, or by separately reacting the purified compound in its free acid or free base form with a suitable base or acid, respectively.
Pharmaceutically acceptable acid addition salts can be formed with inorganic acids and organic acids, e.g., acetate, aspartate, benzoate, besylate, bromide/hydrobromide, bicarbonate/carbonate, bisulfate/sulfate, camphorsulfonate, chloride/hydrochloride, chlortheophyllonate, citrate, ethandisulfonate, fumarate, gluceptate, gluconate, glucuronate, hippurate, hydroiodide/iodide, isethionate, lactate, lactobionate, laurylsulfate, malate, maleate, malonate, mandelate, mesylate, methylsulphate, naphthoate, napsylate, nicotinate, nitrate, octadecanoate, oleate, oxalate, palmitate, pamoate, phosphate/hydrogen phosphate/dihydrogen phosphate, polygalacturonate, propionate, stearate, succinate, sulfosalicylate, tartrate, tosylate and trifluoroacetate salts.
Inorganic acids from which salts can be derived include, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like.
Organic acids from which salts can be derived include, for example, acetic acid, propionic acid, glycolic acid, oxalic acid, maleic acid, malonic acid, succinic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, toluenesulfonic acid, sulfosalicylic acid, and the like. Pharmaceutically acceptable base addition salts can be formed with inorganic and organic bases.
Inorganic bases from which salts can be derived include, for example, ammonium salts and metals from columns I to XII of the periodic table. In certain embodiments, the salts are derived from sodium, potassium, ammonium, calcium, magnesium, iron, silver, zinc, and copper; particularly suitable salts include ammonium, potassium, sodium, calcium and magnesium salts.
Organic bases from which salts can be derived include, for example, primary, secondary, and tertiary amines, substituted amines including naturally occurring substituted amines, cyclic amines, basic ion exchange resins, and the like. Certain organic amines include isopropylamine, benzathine, cholinate, diethanolamine, diethylamine, lysine, meglumine, piperazine and tromethamine.
The pharmaceutically acceptable salts of the present invention can be synthesized from a basic or acidic moiety, by conventional chemical methods. Generally, such salts can be prepared by reacting free acid forms of these compounds with a stoichiometric amount of the appropriate base (such as Na, Ca, Mg, or K hydroxide, carbonate, bicarbonate or the like), or by reacting free base forms of these compounds with a stoichiometric amount of the appropriate acid. Such reactions are typically carried out in water or in an organic solvent, or in a mixture of the two. Generally, use of non-aqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile is desirable, where practicable. Lists of additional suitable salts can be found, e.g., in “Remington's Pharmaceutical Sciences”, 20th ed., Mack Publishing Company, Easton, Pa., (1985); and in “Handbook of Pharmaceutical Salts: Properties, Selection, and Use” by Stahl and Wermuth (Wiley-VCH, Weinheim, Germany, 2002).
Solvates, including pharmaceutically acceptable solvates, of the compounds of formula (I) may also be prepared. “Solvate” refers to a complex of variable stoichiometry formed by a solute and solvent. Such solvents for the purpose of the invention may not interfere with the biological activity of the solute. Examples of suitable solvents include, but are not limited to, water, MeOH, EtOH, and AcOH. Solvates wherein water is the solvent molecule are typically referred to as hydrates. Hydrates include compositions containing stoichiometric amounts of water, as well as compositions containing variable amounts of water.
The compounds of formula (I), including salts and solvates thereof, may exist in crystalline forms, non-crystalline forms, or mixtures thereof. The compound or salt or solvate thereof may also exhibit polymorphism, i.e. the capacity of occurring in different crystalline forms. These different crystalline forms are typically known as “polymorphs”. Polymorphs have the same chemical composition but differ in packing, geometrical arrangement, and other descriptive properties of crystalline solid state. Polymorphs, therefore, may have different physical properties such as shape, density, hardness, deformability, stability, and dissolution properties. Polymorphs typically exhibit different melting points, IR spectra, and X-ray powder diffraction patterns, all of which may be used for identification. One of ordinary skill in the art will appreciate that different polymorphs may be produced, for example, by changing or adjusting the conditions used in crystallizing/recrystallizing a compound of formula (I).
The invention also includes various isomers of the compounds of formula (I). “Isomer” refers to compounds that have the same composition and molecular weight but differ in physical and/or chemical properties. The structural difference may be in constitution (geometric isomers) or in the ability to rotate the plane of polarized light (stereosiomers). With regard to stereoisomers, the compounds of formula (I) may have one or more asymmetric carbon atom and may occur as racemates, racemic mixtures and as individual enantiomers or diastereomers. All such isomeric forms are included within the present invention, including mixtures thereof, unless specifically indicated otherwise. If the compound contains a double bond, the substituent may be in the E or Z configuration. If the compound contains a disubstituted cycloalkyl, the cycloalkyl substituent may have a cis- or trans-configuration. All tautomeric forms are also intended to be included.
Any asymmetric atom (e.g., carbon or the like) of a compound of formula (I) can be present in racemic or enantiomerically enriched, for example the (R)-, (S)- or (R,S)-configuration. In certain embodiments, each asymmetric atom has at least 50% enantiomeric excess, at least 60% enantiomeric excess, at least 70% enantiomeric excess, at least 80% enantiomeric excess, at least 90% enantiomeric excess, at least 95% enantiomeric excess, or at least 99% enantiomeric excess in the (R)- or (S)-configuration. Substituents at atoms with unsaturated double bonds may, if possible, be present in cis-(Z)- or trans-(E)-form.
Accordingly, as used herein a compound of formula (I) can be in the form of one of the possible isomers, rotamers, atropisomers, tautomers or mixtures thereof, for example, as substantially pure geometric (cis or trans) isomers, diastereomers, optical isomers, racemates or mixtures thereof.
Any resulting mixtures of isomers can be separated on the basis of the physicochemical differences of the constituents, into the pure or substantially pure geometric or optical isomers, diastereomers, racemates, for example, by chromatography and/or fractional crystallization.
Any resulting racemates of final products or intermediates can be resolved into the optical isomers by known methods, e.g., by separation of the diastereomeric salts thereof, obtained with an optically active acid or base, and liberating the optically active acidic or basic compound. In particular, a basic moiety may thus be employed to resolve the compounds of the present invention into their optical isomers, e.g., by fractional crystallization of a salt formed with an optically active acid, e.g., tartaric acid, dibenzoyl tartaric acid, diacetyl tartaric acid, di-O,O′-p-toluoyl tartaric acid, mandelic acid, malic acid or camphor-10-sulfonic acid. Racemic products can also be resolved by chiral chromatography, e.g., high pressure liquid chromatography (HPLC) using a chiral adsorbent.
The invention includes unlabeled forms as well as isotopically labeled forms of compounds of formula (I). Isotopically labeled compounds have structures depicted by the formulas given herein except that one or more atoms are replaced by an atom having a selected atomic mass or mass number. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine, and chlorine, such as 2H, 3H, 11C, 13C, 14C, 15N, 18F 31P, 32P, 35S, 36Cl, 125I respectively. The invention includes various isotopically labeled compounds as defined herein, for example those into which radioactive isotopes, such as 3H and 14C, or those into which non-radioactive isotopes, such as 2H and 13C are present. Such isotopically labelled compounds are useful in metabolic studies (with 14C), reaction kinetic studies (with, for example 2H or 3H), detection or imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT) including drug or substrate tissue distribution assays, or in radioactive treatment of patients. In particular, an 18F or labeled compound may be particularly desirable for PET or SPECT studies. Isotopically-labeled compounds of formula (I) can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described in the accompanying Examples and Preparations using an appropriate isotopically-labeled reagent in place of the non-labeled reagent previously employed.
Furthermore, substitution with heavier isotopes, particularly deuterium (i.e., 2H or D) may afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements or an improvement in therapeutic index. It is understood that deuterium in this context is regarded as a substituent of a compound of the formula (I). The concentration of such a heavier isotope, specifically deuterium, may be defined by the isotopic enrichment factor. The term “isotopic enrichment factor” as used herein means the ratio between the isotopic abundance and the natural abundance of a specified isotope. If a substituent in a compound of this invention is denoted deuterium, such compound has an isotopic enrichment factor for each designated deuterium atom of at least 3500 (52.5% deuterium incorporation at each designated deuterium atom), at least 4000 (60% deuterium incorporation), at least 4500 (67.5% deuterium incorporation), at least 5000 (75% deuterium incorporation), at least 5500 (82.5% deuterium incorporation), at least 6000 (90% deuterium incorporation), at least 6333.3 (95% deuterium incorporation), at least 6466.7 (97% deuterium incorporation), at least 6600 (99% deuterium incorporation), or at least 6633.3 (99.5% deuterium incorporation).

Certain compounds of the present invention were found to have improved preclinical properties. For example, certain compounds of the present invention were found to have maintained potency against mIDH1 (for example IDH R132H and/or R132C) in biochemical and/or cellular activity assays, while at the same time improving in-vitro absorption, distribution, metabolism and excretion (ADME) properties. For example, certain compounds of the present invention were found to have reduced clearance rates in rat and/or mouse and/or human in vitro liver microsomal stability assays. Stability in the presence of liver microsomes is important because it can be predictive of in-vivo clearance, and therefore also be predictive of whether or not a compound will have an adequate systemic exposure profile in the human body to effect the desired pharmacological response. Lower clearance rates, i.e. the more stable the compound is in the presence of liver microsomes in vitro, suggests the compound is more likely to have adequate systemic exposure in humans.
General Synthetic Procedures
The compounds of the present invention may be made by a variety of methods, including standard chemistry. Suitable synthetic routes are depicted in the Schemes given below.
The compounds of formula (I) may be prepared by methods known in the art of organic synthesis as set forth in part by the following synthetic schemes. In the schemes described below, it is well understood that protecting groups for sensitive or reactive groups are employed where necessary in accordance with general principles or chemistry. Protecting groups are manipulated according to standard methods of organic synthesis (T. W. Greene and P. G. M. Wuts, “Protective Groups in Organic Synthesis”, Third edition, Wiley, New York 1999). These groups are removed at a convenient stage of the compound synthesis using methods that are readily apparent to those skilled in the art. The selection processes, as well as the reaction conditions and order of their execution, shall be consistent with the preparation of compounds of formula (I).
Those skilled in the art will recognize if a stereocenter exists in the compounds of formula (I). Accordingly, the present invention includes both possible stereoisomers and includes not only racemic compounds but the individual enantiomers and/or diastereomers as well. When a compound is desired as a single enantiomer or diastereomer, it may be obtained by stereospecific synthesis or by resolution of the final product or any convenient intermediate. Resolution of the final product, an intermediate, or a starting material may be effected by any suitable method known in the art. See, for example, “Stereochemistry of Organic Compounds” by E. L. Eliel, S. H. Wilen, and L. N. Mander (Wiley-Interscience, 1994).
The compounds described herein may be made from commercially available starting materials or synthesized using known organic, inorganic, and/or enzymatic processes.




wherein R2 is CH2R2aR2b 

Non-commercial aminoacids can be prepared following the procedures of Scheme 1. Conversion of ketone 1 to the corresponding imidazolidine-2,4-dione 2 followed by hydrolysis provides aminoacid 3.





When aminoalcohol, precursor of oxazolidinone, is not commercially available, it can be prepared from aminoacid 3 following the procedures of Scheme 2. When R3=R4, protected aminoester 5 is treated with an appropriate Grignard reagent to give protected aminoalcohol 6 which goes through basic or acidic deprotection step. When R3=R4, protected aminoacid 8 is converted into Weinreb amide 9 which is treated with different Grignard reagents sequentially to provide protected aminoalcohol 10. Either basic or acidic deprotection of 10 gives 11. Insertion of CO unit into 7 or 11 to provide oxazolidinone 12 is accomplished with several reagents, including (but not limited to) triphosgene, Et2CO3 or N—N′-darbonyldiimidazole, as shown in Scheme 2.




Oxazolidinone 12 is coupled with dihalogen-pyrimidine 13 in the presence of NaH and the resulting 14 is treated with primary amine 15 under several different reaction conditions as shown in Scheme 3 to provide 16.




Alternately intermediate 14 can be prepared by coupling the amino alcohol 11 and dihalogen-pyrimidine 13 in the presence of a base such as diisopropylethyl amine resulting in intermediate 17 which can be treated with triphosgene in the presence of a base such as 2,6-lutidine resulting in intermediate 14.




Intermediate 14 can undergo modification of functional groups on R1, R2, R3 or R4 prior to transformation to compound 16 as described in Scheme 3.
Methods of Use
The compounds of the present invention are inhibitors of a mutant IDH protein having a neomorphic activity and are therefore useful in the treatment of diseases or disorders associated with such proteins including, but not limited to, cell proliferation disorders, such as cancer.
Examples of a mutant IDH protein having a neomorphic activity are mutant IDH1 and mutant IDH2. A neomorphic activity associated with mutant IDH1 and mutant IDH2 is the ability to produce 2-hydroxyglutarate (2-HG neomorphic activity), specifically R-2-HG (R-2-HG neomorphic activity). Mutations in IDH1 associated with 2-HG neomorphic activity, specifically R-2-HG neomorphic activity, include mutations at residues 97, 100, and 132, e.g. G97D, R100Q, R132H, R132C, R132S, R132G, R132L, and R132V. Mutations in IDH2 associated with 2-HG neoactivity, specifically R-2-HG neomorphic activity, include mutations at residues 140 and 172, e.g. R140Q, R140G, R172K, R172M, R172S, R172G, and R172W.

For example, a neomorphic activity associated with a mutant form of IDH1 and IDH2 is the ability to reduce alpha-ketoglutarate to 2-hydroxyglutarate (i.e. 2-HG, specifically R-2-HG). The wild type form of IDH1 and IDH2 does not have the ability to reduce alpha-ketoglutarate to 2-hydroxyglutarate (i.e. 2-HG, specifically R-2-HG) or if it does have this ability, it does not produce significant (i.e. harmful or disease causing) amounts of 2-HG.
As used herein, the term “subject” refers to an animal. Typically the animal is a mammal. A subject also refers to for example, primates (e.g., humans, male or female), cows, sheep, goats, horses, dogs, cats, rabbits, rats, mice, fish, birds and the like. In certain embodiments, the subject is a primate. In yet other embodiments, the subject is a human.
As used herein, the term “therapeutically effective amount” in reference to a compound of the invention means an amount of the compound sufficient to treat the subject's disease or condition, but low enough to avoid serious sides effects (at a reasonable benefit/risk ratio) within the scope of sound medical judgment. A therapeutically effective amount of a compound will vary with the particular compound chosen (e.g. consider the potency, efficacy, and half-life of the compound); the route of administration chosen; the condition being treated; the severity of the condition being treated; the age, size, weight, and physical condition of the subject being treated; the medical history of the subject being treated; the duration of the treatment; the nature of the concurrent therapy; the desired therapeutic effect; and like factors and can be routinely determined by the skilled artisan.
As used herein, the term “treat”, “treating” or “treatment” of any disease or disorder refers in one embodiment, to ameliorating the disease or disorder (i.e., slowing or arresting or reducing the development of the disease or at least one of the clinical symptoms thereof). In another embodiment “treat”, “treating” or “treatment” refers to alleviating or ameliorating at least one physical parameter including those which may not be discernible by the patient. In yet another embodiment, “treat”, “treating” or “treatment” refers to modulating the disease or disorder, either physically, (e.g., stabilization of a discernible symptom), physiologically, (e.g., stabilization of a physical parameter), or both. In yet another embodiment, “treat”, “treating” or “treatment” refers to preventing or delaying the onset or development or progression of the disease or disorder.
As used herein, a subject is “in need of” a treatment if such subject would benefit biologically, medically or in quality of life from such treatment.
The compounds of the present invention may be administered by any suitable route including oral and parenteral administration. Parenteral administration is typically by injection or infusion and includes intravenous, intramuscular, and subcontaneous injection or infusion.
The compounds of the invention may be administered once or according to a dosing regimen wherein a number of doses are administered at varying intervals of time for a given period of time. For example, doses may be administered one, two, three, or four times per day. Doses may be administered until the desired therapeutic effect is achieved or indefinitely to maintain the desired therapeutic effect. Suitable dosing regimens for a compound of the invention depend on the pharmacokinetic properties of that compound, such as absorption, distribution and half life which can be determined by the skilled artisan. In addition, suitable dosing regimens, including the duration such regimens are administered, for a compound of the invention depend on the disease or condition being treated, the severity of the disease or condition, the age and physical condition of the subject being treated, the medical history of the subject being treated, the nature of concurrent therapy, the desired therapeutic effect, and like factors within the knowledge and expertise of the skilled artisan. It will be further understood by such skilled artisans that suitable dosing regimens may require adjustment given an individual subject's response to the dosing regimen or over time as the individual subject needs change. Typical daily dosages may vary depending upon the particular route of administration chosen. Typical daily dosages for oral administration, to a human weighing approximately 70 kg would range from about 5 mg to about 500 mg of a compound of formula (I).

Compositions
In another aspect, the present invention provides a pharmaceutical composition comprising a compound of formula (I) and a pharmaceutically acceptable carrier or excipient.
The pharmaceutical compositions of the invention may be prepared and packaged in bulk form wherein a therapeutically effective amount of a compound of the invention can be extracted and then given to a subject, such as with powders or syrups. Alternatively, the pharmaceutical compositions of the invention may be prepared and packaged in unit dosage form wherein each physically discrete unit contains a therapeutically effective amount of a compound of the invention. When prepared in unit dosage form, the pharmaceutical compositions of the invention typically contain from about 5 mg to 500 mg of a compound of formula (I).
As used herein the term “pharmaceutically acceptable carrier or excipient” means a pharmaceutically acceptable material, composition or vehicle that, for example, are involved in giving form or consistency to the pharmaceutical composition. Each excipient must be compatible with the other ingredients of the pharmaceutical composition when commingled such that interactions which would substantially reduce the efficacy of the compound of the invention when administered to a subject and interactions which would result in pharmaceutical compositions that are not pharmaceutically acceptable are avoided. In addition, each excipient must, of course, be of sufficiently high purity to render it pharmaceutically acceptable.
The compound of the invention and the pharmaceutically acceptable carrier or excipient(s) will typically be formulated into a dosage form adapted for administration to the subject by the desired route of administration. For example, dosage forms include those adapted for (1) oral administration such as tablets, capsules, caplets, pills, troches, powders, syrups, elixirs, suspensions, solutions, emulsions, sachets, and cachets; and (2) parenteral administration such as sterile solutions, suspensions, and powders for reconstitution. Suitable pharmaceutically acceptable excipients will vary depending upon the particular dosage form chosen. In addition, suitable pharmaceutically acceptable excipients may be chosen for a particular function that they may serve in the composition. For example, certain pharmaceutically acceptable excipients may be chosen for their ability to facilitate the production of uniform dosage forms. Certain pharmaceutically acceptable excipients may be chosen for their ability to facilitate the production of stable dosage forms. Certain pharmaceutically acceptable excipients may be chosen for their ability to facilitate the carrying or transporting of the compound or compounds of the invention, once administered to the subject, from one organ or portion of the body to another organ or another portion of the body. Certain pharmaceutically acceptable excipients may be chosen for their ability to enhance patient compliance.
Suitable pharmaceutically acceptable excipients include the following types of excipients: diluents, lubricants, binders, disintegrants, fillers, glidants, granulating agents, coating agents, wetting agents, solvents, co-solvents, suspending agents, emulsifiers, sweeteners, flavoring agents, flavor masking agents, coloring agents, anti-caking agents, hemectants, chelating agents, plasticizers, viscosity increasing agents, antioxidants, preservatives, stabilizers, surfactants, and buffering agents.
Skilled artisans possess the knowledge and skill in the art to enable them to select suitable pharmaceutically acceptable carriers and excipients in appropriate amounts for the use in the invention. In addition, there are a number of resources available to the skilled artisan, which describe pharmaceutically acceptable carriers and excipients and may be useful in selecting suitable pharmaceutically acceptable carriers and excipients. Examples include Remington's Pharmaceutical Sciences (Mack Publishing Company), The Handbook of Pharmaceutical Additives (Gower Publishing Limited), and The Handbook of Pharmaceutical Excipients (the American Pharmaceutical Association and the Pharmaceutical Press).

The oral solid dosage form may further comprise a binder. Suitable binders include starch (e.g. corn starch, potato starch, and pre-gelatinized starch) gelatin, acacia, sodium alginate, alginic acid, tragacanth, guar gum, povidone, and cellulose and its derivatives (e.g. microcrystalline cellulose). The oral solid dosage form may further comprise a disintegrant. Suitable disintegrants include crospovidone, sodium starch glycolate, croscarmelose, alginic acid, and sodium carboxymethyl cellulose. The oral solid dosage form may further comprise a lubricant. Suitable lubricants include stearic acid, magnesium stearate, calcium stearate, and talc.
Where appropriate, dosage unit formulations for oral administration can be microencapsulated. The composition can also be prepared to prolong or sustain the release as, for example, by coating or embedding particulate material in polymers, wax, or the like.
The compounds of the invention may also be coupled with soluble polymers as targetable drug carriers. Such polymers can include polyvinylpyrrolidone, pyrancopolymer, polyhydroxypropylmethacrylamidephenol, polyhydroxyethylaspartamidephenol, or polyethyleneoxidepolylysine substituted with palmitoyl residues. Furthermore, the compounds of the invention may be coupled to a class of biodegradable polymers useful in achieving controlled release of a drug, for example polylactic acid, polepsilon caprolactone, polyhydroxy butyric acid, polyorthoesters, polyacetals, polydihydropyrans, polycyanacrylates and cross-linked or amphipathic block copolymers of hydrogels.
In another aspect, the invention is directed to a liquid oral dosage form. Oral liquids such as solution, syrups and elixirs can be prepared in dosage unit form so that a given quantity contains a predetermined amount of a compound of the invention. Syrups can be prepared by dissolving the compound of the invention in a suitably flavored aqueous solution; while elixirs are prepared through the use of a non-toxic alcoholic vehicle. Suspensions can be formulated by dispersing the compound of the invention in a non-toxic vehicle. Solubilizers and emulsifiers such as ethoxylated isostearyl alcohols and polyoxy ethylene sorbitol ethers, preservatives, flavor additives such as peppermint oil or other natural sweeteners or saccharin or other artificial sweeteners and the like can also be added.
In another aspect, the invention is directed to parenteral administration. Pharmaceutical compositions adapted for parenteral administration include aqueous and non-aqueous sterile injection solutions which may contain anti-oxidants, 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. The compositions may be presented 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 the sterile liquid carrier, for example water for injections, immediately prior to use. Extemporaneous injection solutions and suspensions may be prepared from sterile powders, granules and tablets.

Step 1
To a mixture of 1H-imidazole-4-carbaldehyde (3.71 g, 38.6 mmol), 1-chloro-4-iodobenzene (13.81 g, 57.9 mmol), (1R,2R)—N1,N2-dimethylcyclohexane-1,2-diamine (1.10 g, 7.72 mmol), copper(I) iodide (0.368 g, 1.93 mmol) and cesium carbonate (25.2 g, 77 mmol) was added DMF (50 mL). The reaction was sealed and heated to 110° C. for 18 hours. The reaction mixture was then cooled to room temperature and diluted with a saturated solution of NH4Cl. A brown solid develops. Solid was collected, washed with water and air dried. Solid material was then dissolved in 10% MeOH:90% DCM solution and dried (Na2SO4), filtered and concentrated to afford a dark brown solid 1-(4-chlorophenyl)-1H-imidazole-4-carbaldehyde (8.55 g, 41.4 mmol, 107% yield). Material as used without further purification. LCMS m/z 207.1 (M+H)+, Rt 0.58 min.

Step 1
To a round bottom flask containing (R)—N—((S)-1-(2-fluoro-4-(prop-1-en-2-yl)phenyl)ethyl)-2-methylpropane-2-sulfinamide (1.02 g, 3.60 mmol) was added dioxane (7 mL). To this homogenous solution was then added HCl in Dioxane (1.80 mL, 7.20 mmol, 4 M). Resulting reaction mixture allowed to stir 10 min at room temperature. Volatiles removed. Et2O was added and mixture sonnicated briefly. Volatiles removed again. Et2O was added and the solid collected and washed with Et2O to afford a white HCl salt of (S)-1-(2-fluoro-4-(prop-1-en-2-yl)phenyl)ethanamine (742 mg, 3.44 mmol, 96% yield). 1H NMR (400 MHz, D2O) δ 1.65 (d, J=6.94 Hz, 3H) 2.12 (s, 3H) 5.23 (s, 1H) 5.50 (s, 1H) 7.37 (d, J=13.06 Hz, 1H) 7.43 (m, 2H). LCMS m/z 163.2 (deamino fragment) (M+H)+, Rt 0.56 min.
Step 2
To a RBF containing (S)-1-(2-fluoro-4-(prop-1-en-2-yl)phenyl)ethanamine (742 mg, 3.44 mmol) was added NMP (7 mL). To this solution was then added TEA (959 μl, 6.88 mmol) followed by the addition of Di-tert-butyl dicarbonate (976 mg, 4.47 mmol). Resulting reaction mixture allowed to stir 2 hr at room temperature. Reaction mixture was diluted with water and extracted with EtOAc. Organic phases combined, washed with water, brine, dried (Na2SO4), filtered and concentrated onto silica gel. Silica gel column chromatography (EtOAc/Heptanes 0 to 100%) provided (S)-tert-butyl (1-(2-fluoro-4-(prop-1-en-2-yl)phenyl)ethyl)carbamate (1.28 g, 4.58 mmol, 133% yield) as a white crystalline. 1H NMR (400 MHz, CDCl3) δ 1.40-1.48 (m, 12H) 2.12 (d, J=0.44 Hz, 3H) 4.98 (br. s., 2H) 5.10-5.12 (m, 1H) 5.37 (s, 1H) 7.11-7.16 (m, 1H) 7.19-7.24 (m, 2H). LCMS m/z 163.0 (deamino fragment) (M+H)+, Rt 1.13 min.
Step 3
To a round bottom flask containing (S)-tert-butyl (1-(2-fluoro-4-(prop-1-en-2-yl)phenyl)ethyl)carbamate (1.28 g, 4.58 mmol) was added DCM (23 mL). The homogenous solution was cooled to −70° C. in a acetone/dry ice bath. Ozone (g) was then gently bubbled through the solution for 25 min at which time the solution becomes pale blue in color. Dimethyl sulfide (1.02 mL, 13.8 mmol) was then added to the cold solution and mixture gradually allowed to warm to room temperature and stirred for 30 min. Reaction mixture was diluted with a water. Phases partitioned. Aqueous phase extracted with DCM. Organic phases combined, washed with brine, dried (Na2SO4), filtered and concentrated onto silica gel. Silica gel column chromatography (EtOAc/Heptane 0 to 60%) provided (S)-tert-butyl (1-(4-acetyl-2-fluorophenyl)ethyl)carbamate (296 mg, 1.05 mmol, 23% yield) as a colorless oil that crystallizes upon standing. 1H NMR (400 MHz, CDCl3) δ 1.38-1.49 (m, 12H) 2.59 (s, 3H) 5.01 (br. s., 1H) 7.40 (t, J=7.65 Hz, 1H) 7.62 (dd, J=11.20, 1.57 Hz, 1H) 7.71 (dd, J=7.95, 1.54 Hz, 1H).

(S)-4-((R)-1-aminoethyl)-3-(2-(((S)-1-(2-(4-chlorophenyl)thiazol-5-yl)ethyl)amino)pyrimidin-4-yl)oxazolidin-2-one




Step 1
To a microwave vial with stir bar was added (R)-4-((S)-1-(tert-butoxy)ethyl)-3-(2-chloropyrimidin-4-yl)oxazolidin-2-one (147 mg, 0.49 mmol) and DMSO (4 mL). To this reaction mixture was added (S)-1-(2-(4-chlorophenyl)thiazol-5-yl)ethanamine HCl (148 mg, 0.54 mmol) and DIEA (0.26 mL, 1.47 mmol). Vial capped and the reaction mixture was heated in a preheated sand bath at 110° C. for 42 hr. The reaction mixture was diluted with water and extracted with EtOAc. Organic phases combined, washed with water, brine, dried (Na2SO4), filtered and concentrated onto silica gel. Silica gel column chromatography (EtOAc/Heptane 0 to 100%) provided (R)-4-((S)-1-(tert-butoxy)ethyl)-3-(2-(((S)-1-(2-(4-chlorophenyl)thiazol-5-yl)ethyl)amino)pyrimidin-4-yl)oxazolidin-2-one (82 mg, 0.16 mmol, 33% yield). 1H NMR (400 MHz, CDCl3) δ 0.82 (br. s., 9H) 0.90-0.98 (m, 3H) 1.71 (d, J=6.90 Hz, 3H) 4.13 (q, J=7.16 Hz, 1H) 4.21-4.32 (m, 1H) 4.42-4.51 (m, 1H) 4.56 (dd, J=8.31, 2.79 Hz, 1H) 5.39 (br. s., 1H) 7.34-7.45 (m, 2H) 7.57 (d, J=5.77 Hz, 1H) 7.64 (s, 1H) 7.76-7.86 (m, 2H) 8.22 (d, J=5.82 Hz, 1H). LCMS m/z 502.3 (M+H)+, Rt 0.92 min.
Step 2
To a round bottom flask containing a stir bar and (R)-4-((S)-1-(tert-butoxy)ethyl)-3-(2-(((S)-1-(2-(4-chlorophenyl)thiazol-5-yl)ethyl)amino)pyrimidin-4-yl)oxazolidin-2-one (82 mg, 0.16 mmol) was added DCM (1 mL) followed by the addition of TFA (1 mL). Resulting reaction mixture allowed to stir 30 min at RT. The volatiles were then removed and the residue neutralized by the addition of a saturated solution of NaHCO3. The aqueous mixture was then extracted with DCM. Organic phases combined, washed with water, brine, dried (Na2SO4), filtered and concentrated to a brown foam of (R)-3-(2-(((S)-1-(2-(4-chlorophenyl)thiazol-5-yl)ethyl)amino)pyrimidin-4-yl)-4-((S)-1-hydroxyethyl)oxazolidin-2-one (61 mg, 0.14 mmol, 84% yield) which was used without further purification. LCMS m/z 446.2 (M+H)+, Rt 0.71 min.
Step 3
To a round bottom flask with stir bar was added (R)-3-(2-(((S)-1-(2-(4-chlorophenyl)thiazol-5-yl)ethyl)amino)pyrimidin-4-yl)-4-((S)-1-hydroxyethyl)oxazolidin-2-one (19 mg, 0.04 mmol) followed by the addition of DCM (1 mL) under nitrogen. Mixture was cooled to 0° C. in a ice/water bath. To this cold solution was added DIEA (0.03 mL, 0.17 mmol) followed by the addition of methanesulfonyl chloride (10 μL, 0.13 mmol). Reaction mixture stirred for 1 hr at 0° C. The reaction mixture was then quenched with water and diluted with DCM. Phases partitioned and the aqueous phase extracted with DCM. Organic layers combined and washed with brine, dried (Na2SO4), filtered and concentrated to afford a orange residue of (S)-1-((R)-3-(2-(((S)-1-(2-(4-chlorophenyl)thiazol-5-yl)ethyl)amino)pyrimidin-4-yl)-2-oxooxazolidin-4-yl)ethyl methanesulfonate (21 mg, 0.04 mmol, 94% yield).

Example 466 was prepared by a convergent route. Steps 1a-1c give (S)-1-(4-methyl-2′-(trifluoromethyl)-[3,4′-bipyridin]-6-yl)ethanamine. Steps 2a-2f give (R)-4-((S)-1-fluoroethyl)-3-(2-fluoropyrimidin-4-yl)oxazolidin-2-one. These intermediates were combined in Step 3 to give (R)-4-((S)-1-fluoroethyl)-3-(2-(((S)-1-(4-methyl-2′-(trifluoromethyl)-[3,4′-bipyridin]-6-yl)ethyl)amino)pyrimidin-4-yl)oxazolidin-2-one.
Step 1a: To a solution of (S)-1-(5-bromo-4-methylpyridin-2-yl)ethanamine hydrochloride (750 mg, 2.98 mmol) in DCM (30 mL) was added di-tert-butyl dicarbonate (0.761 mL, 3.28 mmol) and triethylamine (1.25 mL, 8.94 mmol). The resulting solution was stirred at r.t. overnight. Mixture was concentrated under reduced pressure and diluted with 40 mL EtOAc, washed with water, brine, dried over Na2SO4 and concentrated to give 940 mg of (S)-tert-butyl (1-(5-bromo-4-methylpyridin-2-yl)ethyl)carbamate as a light brown oil.

The crude product was used to next step without further purification.
Step 2a: A solution of (2S,3R)-2-(((benzyloxy)carbonyl)amino)-3-(tert-butoxy)butanoic acid dicyclohexylammonium salt (500 mg, 1.0 mmol) in 10 ml of THF and isobutyl chloroformate (167 mg, 1.2 mmol, 1.2 equiv) at −25° C. was added N-methylmorpholine (124 mg, 1.2 mmol, 1.2 equiv), the mixture was stirred at same temperature for 10 min and filtered. The filtrate was cooled to −20° C. and to it was added NaBH4, followed by 2 ml of water immediately afterwards. The reaction mixture was stirred at same temperature for 5 min. then gradually warmed to room temperature for 25 min, poured into water (10 ml) and extracted with ethyl acetate (2×20 ml). The combined organic phases were washed with water, brine and dried over Na2SO4. The solvent was removed to yield benzyl ((2R)-(3R)-3-(tert-butoxy)-1-hydroxybutan-2-yl)carbamate as a clear oil. No further purification was required for next step. 1H NMR (400 MHz, CDCl3) δ 7.37-7.16 (m, 5H), 5.25 (d, J=8.0 Hz, 1H), 5.02 (s, 1H), 4.04 (ddd, J=12.0, 8.9, 2.8 Hz, 1H), 3.92-3.75 (m, 1H), 3.59 (dddd, J=32.3, 14.6, 8.2, 4.3 Hz, 2H), 1.10 (s, 9H), 1.09-1.06 (m, 3H).
Step 2b: To a solution of benzyl ((2R,3R)-3-(tert-butoxy)-1-hydroxybutan-2-yl)carbamate (5.88 g, 19.9 mmol) in 100 mL DMF was added NaH (60% in mineral oil, 1.62 g, 40.6 mmol) at 0° C.

Biological Assays and Data
Mutant IDH1 Biochemical Assay: LC-MS Detection of 2-HG.
Mutant IDH1 R132H catalytic activity was monitored using the quantitative liquid chromatography/mass spectrometry (LC-MS) detection of 2-HG, a product of the NADPH-dependent alpha-KG reduction reaction.
More specifically, the biochemical reactions were performed at room temperature in 384-well Greiner flat-bottom plates (Costar, Cat. No. 781201) using a final reaction volume of 30 μL and the following assay buffer conditions: 50 mM HEPES pH 7.4, 10 mM MgCl2, 50 mM KCl, 1 mM DTT, 0.02% BSA, 5 uM NADPH and 100 uM alpha-KG.
The final reaction mixture contained 3.3% DMSO and inhibitors with concentrations ranging 0.02-50 μM. The IDH1 enzyme was used at a final concentration of 0.25 nM. Following 45 minutes incubation, the reaction mixtures were quenched by the addition of 10 μL of 16% formic acid containing 800 nM of 5-carbon labeled 13C-2-HG). The protein was then precipitated by the addition of 2.5 volumes of acetonitrile followed by centrifugation (3000×g, 20 minutes). The concentration of 2-HG in the resulting supernatants was measured by LC-MS (see below).
LC-MS method. Reaction mixture supernatants were submitted to chromatographic separation on a BiobasicAX column (2.1 mm×20 mm, 5 μm particle, Thermo Scientific Inc.). The chromatographic mobile phases were A) 25 mM ammonium biocarbonate and B) acetonitrile (0.1% ammonium hydroxide). Nicotinamide was eluted at 1 ml/min using a 85-5% B gradient over 0.9 minutes (Agilent 1200SL LC system, Thermofisher LX-4 autosampler) and analyzed by multiple reaction monitoring (MRM) on a API4000 QTrap mass spectrometer (ABSciex, Framingham, Mass.) in the positive electrospray ionization (ESI+) mode. The mass transition for 2-HG and 13C-2-HG were 147→129 and 152→134, respectively. The relative responses (2-HG/13C-2-HG) were measured at varied inhibitor concentrations and used to calculate inhibitory IC50 values (normalized IC50 regression curves).
R132 Protein Expression and Purification.
IDH1 R132H was cloned into the pET47b vector using the restriction sites XmaI/XhoI which yields an in frame, N-terminal His6 site cleavable with Prescission protease. This plasmid was transformed into RosettaTM 2 (DE3) (Novagen) cells. In shake flasks, 8 L of cells were grown in Terrific Broth (Teknova) (plus kanamycin 50 μg/mL and chloramphenicol 34 μg/mL) at 37° C. to an OD600 of 0.8 and protein expression was induced by addition of IPTG to a concentration of 0.20 mM. The cells were subsequently grown for 18 hours at 18° C.

Purification

The cells were homogenized in Lysis Buffer with protease inhibitors (cOmplete EDTA-free protease inhibitor tablets (Roche), 1 tablet per 50 mL of buffer), DNAse, and to 200 μM PMSF and lysed in a Microfluidizer. After lysis, Triton X-100 was added to 0.1% and stirred at 4° C. for 30 minutes.
The cleared lysate was loaded onto 2×5 mL HisTrap FF crude columns (GE), washed extensively with Lysis Buffer until the A280 stabilized and eluted with Ni Elution Buffer. Peak eluted fractions were concentrated to 30 mL, EDTA was added to 1 mM and GST-Prescission protease was added to 3 U/100 μg of protein. The sample was dialyzed against 2 L Dialysis Buffer I (MWCO 50 kDa) for 6 hours at 4° C. then dialyzed against 2 L of Dialysis Buffer II for at least 6 more hours. GST-Prescission cleaved sample was rocked with Glutathione Agarose Beads, spun down and then the supernatant was loaded through a 5 mL HisTrap HP column and the flow through was collected.
Flow through was then diluted with ice cold 20 mM Tris pH 7.4 and 1 mM TCEP until the conductivity dropped to less than 5 mS/cm (a roughly three fold dilution). This sample was then flowed through a HiTrap Q column and the flow through was concentrated to 10 mL and loaded onto an equilibrated 26/60 Superdex 200 column using SEC Buffer as the mobile phase. Peak fractions were collected, concentrated and aliquoted.

The results of the mutant IDH1 biochemical assay (mIDH R132H) are given in Table 40. Some of the examples were run in the assay multiple times and therefore the IC50 values are expressed as a range of activity.
Fluorescence Biochemical Assay
The IDH1 (R132H) mutant catalyzes the reduced form of NADP+(NADPH) and α-ketoglutarate (α-KG) to form nicotinamide adenine dinucleotide phosphate (NADP+) and R (−)-2-hydroxyglutarate (2HG). The reaction can be monitored kinetically by following the oxidation of NADPH to NADP+ which is measured using fluorescence, excitation at 355 nm and emission at 530 nm. Reactions were monitored using the Perkin-Elmer Envision, Model 2101. More specifically, the biochemical reactions were performed at room temperature in 384-well Greiner flat-bottom plates (Cat. No. 781076) using a final reaction volume of 20 μL and the following assay buffer conditions: 50 mM HEPES pH 7.5, 10 mM MgCl2, 1 mM DTT, 0.02% BSA, 0.02% Tween-20, 10 μM NADPH and 100 μM α-KG. The final reaction mixture contained 2.5% DMSO and test compounds with concentrations ranging 0.0000008-25 μM. The IDH1 (R132H) enzyme was used at a final concentration of 10 nM. Curve fitting for dose response IC50 determinations was done using a 4-parameter logistic model: y=min+((max−min)/1+(x/IC50)slope)
The results of the fluorescence biochemical assay (mIDH R132H) are given in Table 40. Some of the examples were run in the assay multiple times and therefore the IC50 values are expressed as a range of activity.

IDH Cellular Assay

The IDH cellular assay consisted of two side-by-side comparator assays: 1) 2HG oncometabolite detection assay using LC-MS (See Mutant IDH1 biochemical assay for LC-MS detection details) and 2) Cell proliferation assay to monitor off-target killing of cells and to normalize 2HG level change.
IDH1 cellular screens were run with the HCT-116 cell line (express endogenous level of IDH1mut R132H, available from Horizon Discoveries X-Man isogenic human cell lines, catalog #HD104-013). The cells were grown in DMEM (LONZA Cat#12-540F) with 10% Fetal bovine serum (Gibco cat #10099) and 1× non-essential amino acids (NEAA LONZA cat #13-114E). Panel assays were run periodically to test compound activity in cell lines with different endogenous mutations—HT1080 (IDH1mut R132C, EMEM+10% FBS), SNU-1079 (IDH1mut R132C, RPMI+10% FBS+1% sodium pyruvate), and SW1353 (IDH2mut R172S, RPMI+10% FBS+1% sodium pyruvate).
The assay process was as follows:
Day 1: cells were seeded in 384-well plates (Corning Cat#3707) in triplicates for both the cell proliferation and 2HG assay, and incubated at 37 C, 95% Rh, 5% CO2 overnight.
Day 2: compounds were serially diluted 1:3 (10 point dilution from 10 mM solutions in DMSO) and delivered to the cell assay plates via acoustic dispenser, with final concentration ranging from 30 uM to 1.5 nM. The plates were returned to the incubator after treatment and incubated for 48 hours.
Day 4 Proliferation assay: CTG (cell titer-glo, Promega part #G755B) was added to the assay plates and luminescence signal was read on the plate reader.
Day 4 2HG assay: Extraction sample preparation consisted of aspirating all media from the assay plates, adding 70 ul of 90% methanol in water, dry ice incubation for 15 minutes, centrifuging at 2000 rpm for 30 min to ensure all particulates have settled, and transferring 30 ul of the supernatant into LC-MS ready plates. LC-MS analysis followed.
Certain compounds of the invention were tested in the IDH Cellular Assay.
Determination of Metabolic Stability in Liver Microsomes—Method I
The in vitro metabolic stability assay was performed in a 96-well glass plate with shaking incubation at 37° C. A 10 mM DMSO stock solution of the test compound was sequentially diluted 1:1000 to yield a final reaction concentration of 1 μM in 50 mM KPi. Immediately prior to the start of the experiment, respective animal or human liver microsomes (male Sprague-dawley rat, male CD-1 mouse, or pooled human liver microsomes) were diluted in 50 mM KPi to 1.25 mg/mL liver microsomal protein. 30 μL of the 10 μM solution containing the test compound was added to 120 μL of microsomal protein for 150 μL enzyme-compound mixture. The reaction was initiated by adding 150 μL of cofactor solution (2 mM NADPH, 4 mM MgCl in 50 mM KPi) to the enzyme-compound mixture, and the final reaction concentrations are listed in the table below.

At 0, 5, 10 and 30 minute time points in the reaction, reaction aliquots (50 μL) were removed and the reactions were terminated by the addition of acetonitrile (150 μL) containing a mass spectrometry internal standard (1 μM glyburide). The samples were centrifuged and the supernatants analyzed by LC-MS/MS for quantization of remaining compound. The percentage of compound remaining, relative to 0 minutes, was used to estimate in vitro elimination-rate constant (kmic) which was used to calculate in vitro metabolic clearance rates.
Analysis of the samples was performed on a high performance liquid chromatography-tandem mass spectrometry (LC/MS) system consisting of a Thermo TSQ Quantum Ultra mass spectrometer, an H-ESI ion source, a CTC-HTS Pal autosampler, and an Agilent LC Pump. Samples were separated on an XTerra C18 column, 2.1×20 mm, 3.5 μm using the fast mobile phase gradient outlined below.

Mobile phase A consisted of purified water containing 0.01% formic acid. Mobile phase B consisted of acetonitrile containing 0.01% formic acid. The flow rate was 1 mL/min. The injection volume was 10 μL. Compounds were detected using the Thermo QuikQuan software which collects intensity data for all fragments related to the molecular weight of the test compound. After collection of the raw data, the software identifies and integrates the peak of the strongest intensity.
Each microsomal elimination rate, kmic, was based on a 4-point elimination curve tested in singlet. LC-MS/MS raw data for a reaction plate was returned as integrated analyte peak areas for the test compound and internal standard used in the quench solution for the reaction to enable use of analyte:internal standard peak area ratios (PARs) for all data comparisons. The reaction time point (e.g. 0, 5, 20 or 30 minutes) was plotted versus the natural logarithm of percent test compound remaining relative to 0 minutes (based on relative PAR). The slope of this clearance plot, kmic, was used to calculate the in vitro half-life, t1/2. In order to focus on linear reaction kinetics, whenever possible, data points representing <10% test compound remaining were generally omitted from the definition of the clearance plot slope.
Determination of Metabolic Stability in Liver Microsomes—Method II
The in vitro metabolic stability assay was performed in a 96-deep-well plate with incubation at 37° C. 10 mM DMSO stock solution of the test compound was diluted 1:20 in acetonitrile, followed by an additional 1:10 dilution in 100 mM potassium phosphate buffer (KPi) to yield a final reaction concentration of 1 μM. Immediately prior to the start of the experiment, respective animal or human liver microsomes (male Sprague-dawley rat, male CD-1 mouse, or pooled human liver microsomes) were diluted in 100 mM KPi to 1.25 mg/mL liver microsomal protein. 290 μL of cofactor solution (1.7 mM NADPH, 1.7 mM UDPGA, 3.4 mM MgCl in 100 mM KPi) was added to 200 μL of microsomal protein for a final volume of 490 μL. The reaction was initiated by adding 10 μL of the 50 μM test solution to 490 μL of microsomal protein for a final volume 500 μL enzyme-compound mixture.
The final reaction concentrations are listed in the table below:

At 0, 5, 15 and 30 minute time points in the reaction, reaction aliquots (75 μL) were removed and the reactions were terminated by the addition of 50:50 acetonitrile/methanol solution (75 μL) containing a mass spectrometry internal standard (0.5 μM glyburide). The samples were centrifuged at 4000 RPM for 10 minutes. Supernatants (15 μL aliquots) were transferred to a new plate where each well contains 90 μL of deionized water. The supernatants solution were analyzed by UPLC/MS/MS for quantitation of parent remaining compound under multiple reactions monitoring mode (MRM) in positive mode. The percentage of compound remaining, relative to 0 minutes, was used to estimate in vitro elimination-rate constant (k) which was used to calculate in vitro metabolic clearance rates.
Analysis of the samples was performed on an ultra-performance liquid chromatography-tandem mass spectrometry (UPLC/MS/MS) system consisting of an AB Sciex Qtrap 5500 mass spectrometer, AB Sciex Turbo V ion source, Waters Acquity Sample Organizer, Waters Acquity Column manager, Waters Acquity Sample manager, and a Waters Acquity Binary Solvent Manager. Chromatographic separation of analyte and internal standard was achieved using a reverse phase C-18 column (50×2.1 mm, 1.7 μm, Acquity UPLC BEH C-18) with the following UPLC mobile phases and elution gradient:
UPLC mobile phase A: 0.25% formic acid in 5% methanol; mobile phase B: 0.25% formic acid in 95% water.
