Definitions

  • the invention relates to new pyrrolopyrimidine compounds and pharmaceutical compositions thereof, specifically pyrrolopyrimidine compounds and pharmaceutical compositions thereof which are inhibitors of CDK4/6.
  • the invention is also directed to the use of these compounds and compositions in the treatment of hyperproliferative disorders such as cancer.
  • retinoblastoma protein (pRb) is the checkpoint protein for the G1 to S phase transition.
  • pRb associates with a family of E2F transcription factors to prevent their activity in the absence of appropriate growth stimuli (See Ortega et al., Biochimica et Biophysica Acta-Reviews on Cancer 2002; 1602 (1):73-87; Shapiro, Journal of Clinical On ⁇ logy 2006; 24 (11):1770-1783).
  • quiescent cells Upon mitogen stimulation, quiescent cells begin their entry into S phase by newly synthesizing D-cyclins, which are the activators of cyclin-dependent kinases 4 and 6 (CDK4/6). Once bound by the cyclins, CDK4/6 deactivate the pRb protein via phosphorylation. The phosphorylation of pRb releases E2F to direct the transcription of genes required for S phase. A full deactivation of pRb requires phosphorylations by both cyclin D-CDK4/6 and cyclin E- CDK2. Phosphorylations by CDK4/6 at specific sites of pRb (Ser780, Ser795) have been shown to be a prerequisite for cyclin E-CDK2 phosphorylation.
  • CDK4/6 In addition to D-cyclins, the activity of CDK4/6 is regulated by p16, encoded by INK4a gene, which inhibits the kinase activity.
  • INK4a gene In addition to D-cyclins, the activity of CDK4/6 is regulated by p16, encoded by INK4a gene, which inhibits the kinase activity.
  • the CIP/KIP proteins which are the inhibitors of cyclin E-CDK2, also bind to cyclin D-CDK4/6 complex, and this results in further activation of CDK2 by sequestering the CIP/KIP proteins away from their target.
  • the cyclin D-CDK4/6 is a key enzyme complex that regulates the G1 to S phase.
  • the D-cyclin-CDK4/6-INK4a-pRb pathway is universally disrupted to favor cell proliferation in cancer. In a majority of cases (-80%), cancers maintain a functional pRb and utilize different mechanisms to increase the activity of CDK4/6 kinase.
  • cyclin D1 is translocated to IgH promoter (t11 :14) which results in constitutive expression of the protein, leading to activation of CDK4/6 (See Amin, et al., Archives of Pathology & Laboratory Medicine 2003; 127 (4):424-431; Oudat, et al., Modern Pathology 2001; 14 (1):175A) This translocation is observed in >90% of the MCL cases and considered pathognomic for the disease. The D-cyclin is also translocated in 20% of multiple myelomas. (See Bergsagel et al.,. Immunological Reviews 2003; 194 (1):96-104)
  • D-cyclin abundance can also be increased by amplification or overexpression, and the examples of these can be found in squamous cell esophageal cancer, where a significant portion exhibits cyclin D1 amplification (See Jiang, et ai, Cancer Research 1992; 52 (10):2980 ⁇ 2983) and in breast cancer, where the overexpression of cyclin D1 is frequent (See Arnold et ai, Journal of Clinical Oncology 2005).
  • the CDK4/6 kinase activity can also be increased by amplification of the CDK4 gene itself and the co-amplifications of CDK4 and MDM2 genes are observed in almost all cases of dedifferentiated liposarcomas.
  • CDK4/6 The genetic inhibitor of CDK4/6 is also frequently inactivated in cancer to achieve COK4/6 activation and the examples of this include non small cell lung cancer, melanoma and pancreatic cancer (Brambilla, et ai, Journal of Pathology 1999; 188 (4):351-360; Cowgill et ai, American Journal of Surgery 2003; 186 (3):279-286 Gazzeri, et ai, Oncogene 1998; 16 (4):497-504; Kamb et ai, Science 1994; 264 (5157):436-440, Ortega et ai, Biochimica et Biophysica Ada- Reviews on Cancer 2002; 1602 (1):73-87).
  • the activity of the CDK4/6 kinases can also be enhanced by oncogenic aberrations of the mitogen pathways that increase D-cyclin expression.
  • the examples here include EGFR amplifications in non small cell lung cancer (NSCLC), activating K- Ras mutations in pancreatic cancer, V600E B-Raf mutation in melanoma and PTEN inactivation in colon cancer (See Da tey, et ai, Cytokine & Growth Factor Reviews 2005; 16 (2):233-247; Engelman, Nature Reviews Cancer 2009; 9 (8);550-562; Garcia- Echeverria, Purinergic Signalling 2009; 5 (1); 117-125, Gray-Schopfer et ai, Cancer and Metastasis Reviews 2005; 24 (1):165-183, John, et ai, Oncogene 2009; 28.S14-S23, Sharma, et ai, Nature Reviews Cancer 2007; 7 (3);169-181).

Description

PYRROLOPYRIMIDINE COMPOUNDS AS INHIBITORS OF CDK4/6
FIELD OF THE INVENTION
The invention relates to new pyrrolopyrimidine compounds and pharmaceutical compositions thereof, specifically pyrrolopyrimidine compounds and pharmaceutical compositions thereof which are inhibitors of CDK4/6. The invention is also directed to the use of these compounds and compositions in the treatment of hyperproliferative disorders such as cancer.
BACKGROUND OF THE INVENTION
Mammalian cell cycle progression is a tightly controlled process in which transitions through different phases are conducted in a highly ordered manner and guarded by multiple checkpoints. The retinoblastoma protein (pRb) is the checkpoint protein for the G1 to S phase transition. pRb associates with a family of E2F transcription factors to prevent their activity in the absence of appropriate growth stimuli (See Ortega et al., Biochimica et Biophysica Acta-Reviews on Cancer 2002; 1602 (1):73-87; Shapiro, Journal of Clinical On∞logy 2006; 24 (11):1770-1783). Upon mitogen stimulation, quiescent cells begin their entry into S phase by newly synthesizing D-cyclins, which are the activators of cyclin-dependent kinases 4 and 6 (CDK4/6). Once bound by the cyclins, CDK4/6 deactivate the pRb protein via phosphorylation. The phosphorylation of pRb releases E2F to direct the transcription of genes required for S phase. A full deactivation of pRb requires phosphorylations by both cyclin D-CDK4/6 and cyclin E- CDK2. Phosphorylations by CDK4/6 at specific sites of pRb (Ser780, Ser795) have been shown to be a prerequisite for cyclin E-CDK2 phosphorylation. (See Lundberg et al., Molecular and Cellular Biology 1998;18 (2):753-761) In addition to D-cyclins, the activity of CDK4/6 is regulated by p16, encoded by INK4a gene, which inhibits the kinase activity. (See Kamb et al., Science 1994; 264 (5157):436~440) The CIP/KIP proteins, which are the inhibitors of cyclin E-CDK2, also bind to cyclin D-CDK4/6 complex, and this results in further activation of CDK2 by sequestering the CIP/KIP proteins away from their target. (See Sherr et al., Genes & Development 1999; 13 (12):1501-1512) Therefore, the cyclin D-CDK4/6 is a key enzyme complex that regulates the G1 to S phase.
The D-cyclin-CDK4/6-INK4a-pRb pathway is universally disrupted to favor cell proliferation in cancer. In a majority of cases (-80%), cancers maintain a functional pRb and utilize different mechanisms to increase the activity of CDK4/6 kinase. (See Ortega et al., Biochimica et Biophysica Acta-Reviews on Cancer 2002; 1602 (1):73-87; Shapiro, Journal of Clinical Oncology 2006; 24 (11):1770-1783)) In Mantle cell lymphoma ( CL), cyclin D1 is translocated to IgH promoter (t11 :14) which results in constitutive expression of the protein, leading to activation of CDK4/6 (See Amin, et al., Archives of Pathology & Laboratory Medicine 2003; 127 (4):424-431; Oudat, et al., Modern Pathology 2001; 14 (1):175A) This translocation is observed in >90% of the MCL cases and considered pathognomic for the disease. The D-cyclin is also translocated in 20% of multiple myelomas. (See Bergsagel et al.,. Immunological Reviews 2003; 194 (1):96-104)
In addition to translocation, D-cyclin abundance can also be increased by amplification or overexpression, and the examples of these can be found in squamous cell esophageal cancer, where a significant portion exhibits cyclin D1 amplification (See Jiang, et ai, Cancer Research 1992; 52 (10):2980~2983) and in breast cancer, where the overexpression of cyclin D1 is frequent (See Arnold et ai, Journal of Clinical Oncology 2005). The CDK4/6 kinase activity can also be increased by amplification of the CDK4 gene itself and the co-amplifications of CDK4 and MDM2 genes are observed in almost all cases of dedifferentiated liposarcomas. (See Sirvent, et ai, American Journal of Surgical Pathology 2007; 31 (10):1476-1489) The genetic inhibitor of CDK4/6 is also frequently inactivated in cancer to achieve COK4/6 activation and the examples of this include non small cell lung cancer, melanoma and pancreatic cancer (Brambilla, et ai, Journal of Pathology 1999; 188 (4):351-360; Cowgill et ai, American Journal of Surgery 2003; 186 (3):279-286 Gazzeri, et ai, Oncogene 1998; 16 (4):497-504; Kamb et ai, Science 1994; 264 (5157):436-440, Ortega et ai, Biochimica et Biophysica Ada- Reviews on Cancer 2002; 1602 (1):73-87). In addition to these genetic defects directly related to the D-cyclin-CDK4/6-INK4a-pRb pathway, the activity of the CDK4/6 kinases can also be enhanced by oncogenic aberrations of the mitogen pathways that increase D-cyclin expression. The examples here include EGFR amplifications in non small cell lung cancer (NSCLC), activating K- Ras mutations in pancreatic cancer, V600E B-Raf mutation in melanoma and PTEN inactivation in colon cancer (See Da tey, et ai, Cytokine & Growth Factor Reviews 2005; 16 (2):233-247; Engelman, Nature Reviews Cancer 2009; 9 (8);550-562; Garcia- Echeverria, Purinergic Signalling 2009; 5 (1); 117-125, Gray-Schopfer et ai, Cancer and Metastasis Reviews 2005; 24 (1):165-183, John, et ai, Oncogene 2009; 28.S14-S23, Sharma, et ai, Nature Reviews Cancer 2007; 7 (3);169-181). Taken together, a large number of human neoplasms achieve enhanced cell proliferation by increasing CDK4/6 activity and a small molecule inhibitor of these kinases might provide an effective means to treat these diseases. Inhibitors of CDKs are known and patent applications have been filed on such inhibitors. (See, for example, WO2007/140222)
Thus attempts have been made to prepare compounds that inhibit CDK4 6 activity and a number of such compounds have been disclosed in the art. However, in view of the number of pathological responses that are mediated by CDK4/6, there remains a continuing need for inhibitors of CDK4/6 which can be used in the treatment of a variety of conditions, including cancer.

The skilled artisan will appreciate that salts, including pharmaceutically acceptable salts of the compounds of formula (I) may be prepared. As used herein, the terms "salt" or "salts" refers to an acid addition or base addition salt of a compound of the invention. The term "pharmaceutically acceptable salts" refers to salts that retain the biological effectiveness and properties of the compounds of this invention and, which typically are not biologically or otherwise undesirable. Accordingly the invention is further directed to salts, preferably pharmaceutically acceptable salts, of the compounds of formula (I).
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/su!fate, camphorsulfornate, chloride/hydrochloride, chlortheophyllonate, citrate, ethandisuifonate, 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, subsalicylate, 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 parent compound, 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 Stah! and Wermuth (Wiley-VCH, Weinheim, Germany, 2002).
The compounds according to formula (I) may contain one or more asymmetric centers (also referred to as a chiral center) and may, therefore, exist as individual enantiomers, diastereomers, or other stereoisomeric forms, or as mixtures thereof. Chiral centers, such as chiral carbon atoms, may also be present in a substituent, such as an alkyl group. Where the stereochemistry of a chiral center present in formula (I), or in any chemical structure illustrated herein, is not specified, the structure is intended to encompass any stereoisomer or mixtures thereof. Thus, the compounds according to formula (I) containing one or more chtral centers may be used as racemic mixtures, enantiomertcally enriched mixtures, or as enantiomerically pure individual stereoisomers.
As used herein, the term "isomers" refers to different compounds that have the same molecular formula but differ in arrangement and configuration of the atoms. Also as used herein, the term "an optical isomer" or "a stereoisomer" refers to any of the various stereo isomeric configurations which may exist for a given compound of the present invention and includes geometric isomers. It is understood that a substituent may be attached at a chiral center of a carbon atom. Therefore, the invention includes enantiomers, diastereomers or racemates of the compound. "Enantiomers" are a pair of stereoisomers that are non-supertmposable mirror images of each other. A 1 :1 mixture of a pair of enantiomers is a "racemic" mixture. The term is used to designate a racemic mixture where appropriate. "Diastereoisomers" are stereoisomers that have at least two asymmetric atoms, but which are not mirror-images of each other. The absolute stereochemistry is specified according to the Cahn- Ingold- Prelog R-S system. When a compound is a pure enantiomer the stereochemistry at each chiral carbon may be specified by either R or S. Stereochemistry can also be specified by using a heavy wedge-shaped bond or a hatched line, when the chemical structure of a compound or substituent is drawn. Resolved compounds whose absolute configuration is unknown can be designated (+) or (-) depending on the direction (dextro- or levorotatory) which they rotate plane polarized light at the wavelength of the sodium D line. Certain compounds described herein contain one or more asymmetric centers or axes and may thus give rise to enantiomers, diastereomers, and other stereoisomeric forms that may be defined, in terms of absolute stereochemistry, as (R)- or (S)-. The present invention is meant to include all such possible isomers, including racemic mixtures, optically pure forms and intermediate mixtures. Optically active (R)- and (S)- isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. Any resulting racemates of final products or intermediates can be resolved into the optical antipodes 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 antipodes, 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.
If a compound of the invention contains a double bond, the substituent may be 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 the compound(s) of the present invention can be present in racemic or enantiomerically enriched, for example the (f?)-, (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 bonds may, if possible, be present in cis- (Z)- or trans- (£)- form.
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.
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 the compounds of the present invention. 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).
In addition to the deuterium-containing compounds presently exemplified, any formula given herein is also intended to represent unlabeled forms as well as isotopically labeled forms of the compounds. 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 H, 3H, 11C, 13C, 14C, 15N, 18F 31P, 32P, 35S, ^CI, 25l respectively. The invention includes various isotopically labeled compounds as defined herein, for example those into which radioactive isotopes, such as 3H, 13C, and 4C , are present. Such isotopically labeled 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 this invention and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations described below by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent.
Isotopically-labeled compounds of the present invention 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 Compound Preparations using an appropriate isotopically-labeled reagents in place of the non-labeled reagent previously employed. Furthermore, the compounds of the present invention, including their salts, can also be obtained in the form of their hydrates, or include other solvents used for their crystallization. The compounds of the present invention may inherently or by design form solvates with pharmaceutically acceptable solvents (including water); therefore, it is intended that the invention embrace both solvated and unsolvated forms. The term "solvate" refers to a molecular complex of a compound of the present invention (including pharmaceutically acceptable salts thereof) with one or more solvent molecules. Such solvent molecules are those commonly used in the pharmaceutical art, which are known to be innocuous to the recipient, e.g., water, ethanol, and the like. The term "hydrate" refers to the complex where the solvent molecule is water. Moreover, pharmaceutically acceptable solvates in accordance with the invention include those wherein the solvent of crystallization may be isotopically substituted, e.g. D20, de- acetone, d6-DMSO.
The present invention also provides pro-drugs of the compounds of the present invention that converts in vivo to the compounds of the present invention. A pro-drug is an active or inactive compound that is modified chemically through in vivo physiological action, such as hydrolysis, metabolism and the like, into a compound of this invention following administration of the prodrug to a subject. The suitability and techniques involved in making and using pro-drugs are well known by those skilled in the art. Prodrugs can be conceptually divided into two non-exclusive categories, bioprecursor prodrugs and carrier prodrugs. See The Practice of Medicinal Chemistry, Ch. 31-32 (Ed. Wermuth, Academic Press, San Diego, Calif., 2001 ). Generally, bioprecursor prodrugs are compounds, which are inactive or have low activity compared to the corresponding active drug compound, that contain one or more protective groups and are converted to an active form by metabolism or solvolysis. Both the active drug form and any released metabolic products should have acceptably low toxicity.
Carrier prodrugs are drug compounds that contain a transport moiety, e.g., that improve uptake and/or localized delivery to a site(s) of action. Desirably for such a carrier prodrug, the linkage between the drug moiety and the transport moiety is a covalent bond, the prodrug is inactive or less active than the drug compound, and any released transport moiety is acceptably non-toxic. For prodrugs where the transport moiety is intended to enhance uptake, typically the release of the transport moiety should be rapid. In other cases, it is desirable to utilize a moiety that provides slow release, e.g., certain polymers or other moieties, such as cyclodextrins. Carrier prodrugs can, for example, be used to improve one or more of the following properties: increased lipophilicity, increased duration of pharmacological effects, increased site-specificity, decreased toxicity and adverse reactions, and/or improvement in drug formulation (e.g., stability, water solubility, suppression of an undesirable organoleptic or physiochemical property). For example, lipophilicity can be increased by esterification of (a) hydroxyl groups with lipophilic carboxylic acids (e.g., a carboxylic acid having at least one lipophilic moiety), or (b) carboxylic acid groups with lipophilic alcohols (e.g., an alcohol having at least one lipophilic moiety, for example aliphatic alcohols).
Exemplary prodrugs are, e.g., esters of free carboxylic acids and S-acyl derivatives of thiols and O-acyl derivatives of alcohols or phenols, wherein acyl has a meaning as defined herein. Suitable prodrugs are often pharmaceutically acceptable ester derivatives convertible by solvolysis under physiological conditions to the parent carboxylic acid, e.g., lower alkyl esters, cycloalkyl esters, lower alkenyl esters, benzyl esters, mono- or di-substituted lower alkyl esters, such as the□ -(amino, mono- or di- lower alkylamino, carboxy, lower alkoxycarbonyl)-!ower alkyl esters, the □ -(lower alkanoyloxy, lower alkoxycarbonyl or d Mower a!kylaminocarbonyl)-lower alkyl esters, such as the pivaloy!oxymethyl ester and the like conventionally used in the art. In addition, amines have been masked as aryicarbonyloxymethyl substituted derivatives which are cleaved by esterases in vivo releasing the free drug and formaldehyde (Bundgaard, J. Med. Chem. 2503 (1989)). Moreover, drugs containing an acidic NH group, such as imidazole, imide, indole and the like, have been masked with N- acyloxymethyl groups (Bundgaard, Design of Prodrugs, Elsevier (1985)). Hydroxy groups have been masked as esters and ethers. EP 039,051 (Sloan and Little) discloses annich-base hydroxamic acid prodrugs, their preparation and use. Compositions
In another aspect, the present invention provides a pharmaceutical composition comprising a compound of formula (I) or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier. The pharmaceutical composition can be formulated for particular routes of administration such as oral administration, parenteral administration, and rectal administration, etc. In addition, the pharmaceutical compositions of the present invention can be made up in a solid form (including without limitation capsules, tablets, pills, granules, powders or suppositories), or in a liquid form (including without limitation solutions, suspensions or emulsions). The pharmaceutical compositions can be subjected to conventional pharmaceutical operations such as sterilization and/or can contain conventional inert diluents, lubricating agents, or buffering agents, as well as adjuvants, such as preservatives, stabilizers, wetting agents, emulsifers and buffers, etc.

General procedures for the removal of protecting groups of intermediates
Intermediates which contained protecting groups necessary for the synthesis of final compounds of Formula (I), these protecting groups were removed by standard procedures as described in "Protective Groups in Organic Synthesis, 3rd Edition, by Green and Wutts. Deprotection Method 1 : BOC Removal using HCI
To a stirring solution of the BOC protected amine of a compound of formula 1 , (1. mmol) in dichloromethane (4m L) or other appropriate solvent was added a solution of 4M HCI in dioxane (2.54 ml_, 10.2 mmol, 10eq) at room temperature. The reaction was stirred at room temperature until ail starting material was consumed as determined by LCMS or TLC. The reaction mixture was then filtered and washed with a solvent such as dichloromethane, ethyl acetate or diethyl ether. The residue was collected and taken up in water, basified with 1 M NaOH and extracted with dichloromethane or a 20% isopropyl aclohol-dichioromethane mixture. The combined organic layers were dried over Na2S04, filtered, and concentrated under reduced pressure to a residue. The crude residue was purified by silica gel chromatography using an appropriate mobile phase and then used directly in the next reaction.
Deprotection Method 2: BOC Removal using Trifluoroacetic Acid
To a cold 0°C stirring solution of the BOC protected amine of a compound of Formula 1 , (1. mmol) in dichloromethane (4ml_) or other appropriate solvent was added 4 mi of anhydrous trifluoroacetic acid. The reaction was stirred at O0C and allowed to warm to room temperature and stirr until ail starting material was consumed as determined by LCMS or TLC. The reaction mixture was then concentrated under vacum to a thick residue. The residue was extracted with a mixture of dichloromethane and saturated sodium bicarbonate. The aqueous was back extracted with dichloromethane. For very polar amines, a 20% isopropyl alcohol-dichloromethane mixture was used for the organic extracting solvent. The organic fractions were combined and dried over Na2S04, filtered, and concentrated under reduced pressure to a residue. The combined organic layers were dried over sodium or magnesium sulfate, filtered, and concentrated under reduced pressure to a residue. The crude residue was purified by silica gel chromatography using an appropriate mobile phase and then used directly in the next reaction.
Deprotection Method 3: BOC Removal using Trifluoroacetic Acid
A solution of the BOC protected amine of a compound of formula 1 in CH2CI2 (0.1M) was treated with an equal volume of trifluoroacetic acid at room temperature and stirred at room temperature for 1.0 h. The reaction mixture was concentrated in vacuo and treated with 7 N NH3 in MeOH portionwise until the mixture was neutral. The resultant mixture was concentrated to a thick residue. The resultant residue was then purified by preparative HPLC or silica gel chromatography using 7 N NH3 in MeOH/CH2CI2 and then used directly in the next reaction. General reductive amination procedure
A compound of Formula (I) (1 equivalent) containing either a primary or secondary amine and with an excess (3 to 8 equivalents) of either an aldehyde (for example, formaldehyde, 37% solution in water) or ketone (for example, acetone) were combined into a suitable solvent such as tetrahydrofuran and allowed to stir at RT for 1 hr with magnesium sulfate (1 equivalent). Sodium triacetoxyborohydride (2 equivalents) was then added in a single portion and the reaction was allowed to stir until all starting material was consumed as determined by TLC or LC S. The reaction was then stopped and taken up into ethyl acetate, neutralized with saturated Na2C03 solution, and washed with brine. The aqueous layers were back extracted with ethyl acetate. The organic layers were combined and dried over Na2S04. For very polar amines, a 20% isopropanol-chloroform solution was used as the extracting solvent. The volatiles were removed and the resulting residue was purified by silica gel chromatography using an appropriate mobile phase which gave the desired final product.

CDK4/cyclin D1 Enzymatic Activity Assay
An assay for monitoring CDK4/cyclin D1-catalyzed phos horylation of pRb at the Ser780 site was performed using TR-FRET in a 384-well format, and was used for IC50 determination and kinetic analysis. The reaction was carried out in a 30 μΙ_ volume containing 0.3 nM CDK4/cyclin D1 , 150 nM biotin-pRb (773-924), 3 μΜ ATP, and 1.3% DMSO (or compound in DMSO) in the assay buffer (50 mM HEPES-Na, pH 7.5; 5 mM MgCI2, 1 mM DTT, 0.02% Tween-20, and 0.05% BSA). 3 μΜ ATP was added last to initiate the reaction. The reaction was quenched with 10 μΙ_ of 240 mM EDTA-Na (pH 8.0) after 60 min incubation at 22 °C. The signal was developed by the addition of 40 μΙ_ detection solution containing 40 nM SA-APC, 143 ng/mL anti-phospho-pRb (S780) antibody, and 1 nM Eu-W1024 anti-rabbit IgG antibody in the detection buffer (50 mM HEPES-Na, pH 7.5, 60 mM EDTA-Na, pH 8.0, 0.05% BSA, and 0.1 % Triton X-100). After 60 min incubation in the dark, the plate was read on Envision (Perkin Elmer 2102- 0010).
Human CDK4/cyclin D1 was expressed in Sf21 cells via baculovirus infection.
A CDK6/cyclin D3 enzymatic activity assay can be performed using the general procedures outlined in the CDK4/cyclin D1 enzymatic assay. CDK6/cyclin D3 enzyme complex can be purchased from a commercial source (CarnaBiosciences, Cat. No. 04- 107)
CDK1/cyclin B Enzymatic Activity Assay
A 384-well microtiter IMAP-FP™ (Molecular Devices Trade Mark Technology) endpoint assay was used for CDK1/cyc!in B kinase activity measurements. The same assay was used for IC50 determination of small molecue inhibitors. In general, the kinase reactions were carried out in 20 μΙ_ volumes in the reaction solution, which is composed of 2 μΙ_ compound (in 20% DMSO), 8 μΐ CDK1/cyclin B in the 1x Reaction Buffer (Molecular Devices, Cat. No. R8139), 10 μί, substrate mixture of Tamra Histone-H1 peptide (Molecular Devices, Cat. No. R7384) and ATP (Amersham Pharmacia, Cat. No. 27- 2056-01) in the 1x Reaction Buffer with 1 mM DTT freshly added. The final reaction mixture contains compound (inhibitor) with the concentration varying from 0.005 - 10 μΜ, 2% DMSO, 0.25 nM CDK1/cyclin B, 100 nM Tamra Histone-H1 peptide, and 20 μΜ ATP. All reactions were run at room temperature in black 384-well flat-bottom Costar plates (Corning, Cat. No. 3710) for 120 min then were quenched by the addition of 60 μΐ 400- fold diluted 1x Progressive Binding Buffer A (Molecular Devices, Cat. No. R8139). The fluorescent polarization signals were read on the Evision Multilabel Reader (Perkin Elmer, Envision 2102-0010) after 2-hour incubation at room temperature. Note: IC50 < 0.005 nM or IC50 > 10 μΜ indicates the true IC50 is out of detection range.
CDK4 Cellular Assays
Cell-based assay measuring phosphorylation levels of pRb at the Ser780 site using an enzyme-linked immunosorbent assay (ELISA) method (Table 6). JeKo-1 , a mantle-cell lymphoma cell line, was selected for use in this assay due to its known translocation and subsequent overexpression of cyclin D1. [Ref : Amin, H. M.; McDonnell, T. J.; Medeiros, L. J.; Rassidakis, G. Z.; Leventaki, V.; O'Connor, S. L; Keating, M. J.; Lai, R. Characterization of 4 mantle cell lymphoma cell lines - Establishment of an in vitro study model. Arch. Pathol. Lab. Med. 2003, 127, 424-431].
The pRb expressing JeKo-1 mantle cell lymphoma cell line was grown in complete media consisting of RPMI1640 (Gibco catalog no. 22400-071), 20% FBS (Gibco catalog no. 10082-131), 2 mM L-glutamine (Gibco catalog no. 25030-081), and 1 % Penicillin/Streptomycin (Gibco catalog no. 15140-133). JeKo-1 cells were seeded in Biocoat Cell Environment Poly-D-Lysine 96-we!t tissue culture plates (Becton Dickinson catalog no. 356461) at 20,000 cells/well in 100 pL final volume of complete media. Cells were allowed to adhere overnight. Compounds were prepared as 10 mM stock solution in DMSO and diluted to a concentration of 110 μΜ in complete media in a 96 well tissue culture plate, and then serially diluted four fold, allowing a titration curve of 7 points with a final concentration of 26 nM. 10 μί of the dilution were then transferred to the cell culture plate, resulting in a final concentration range of 10 μΜ to 2 nM. The incubation was carried out at 37 °C with 5% C02. All compounds were tested in triplicates at each concentration. Following compound incubation, the media was removed and the cells were lysed in 35 ML of lysis buffer, consisting of 50 mM Tris.CI, pH 7.2, 120 mM NaCI, 1 mM EDTA, 6 mM EGTA, 1% NP-40, complete protease inhibitor cocktail (Roche, catalog no. 1 1836170001) and a protease inhibitor cocktail from Calbiochem (catalog no. 524525). The plates were placed at 4 °C with vigorous shaking for 5 min to lyse the cells. The resulting lysates contained approximately 1 ug/pL of protein. The 4H1 total pRb antibody from Cell signaling technology (catalog no. 9309) was added to clear MaxiSorp plates (Nunc catalog no. 442404) at a concentration of 50 ng per well in 50 μΙ_ Dulbecco's Phosphate Buffered Saline (DPBS) (Gibco catalog no. 14190-144). Plates were incubated overnight at 4 °C with rocking. After a 250 pL wash with TBST (Teknova catalog no. T9501) and blot-drying, 250 μΙ_ Superblock (Pierce catalog no. 37535) was added to each well. After shaking for 10 minutes, the Superblock solution was replaced with fresh Superblock and plates were incubated on a shaker for an additional 50 min. After blocking, 30 μΙ_ of JeKo-1 cell lysate, containing approximately 10 μg total protein, were added to wells in triplicate. 20 μΙ_ PBS (Gibco catalog no. 10010-023) containing 10% Superblock (Pierce catalog no. 37535) were added to each well for a final reaction volume of 50 μΙ_. Plates were then sealed with Uniseal plate sealers (Whatman catalog no. 7704-0007), and incubated for 2 h at room temperature on a shaker. Plates were washed with 3 x 250 μί TBST. 50 μΙ_ of a 1 :1000 dilution of anti- phospho Rb Ser780 from Cell Signaling (catalog no. 9307) in PBS/10% Superblock were added and the plate was incubated on a shaker for 1 h at room temperature. For all incubation steps, plates were covered with Uniseal plate sealers. Following incubation, plates were washed with 3 x 250 μΙ_ TBST. Next, 50 μΙ_ of a 1 :2500 dilution of donkey- anti-rabbit HRP (Promega catalog no. W401 B) in PBS/10% Superblock were added, and plates were incubated for 30 min at room temperature on a shaker. Plates were again washed as described above. Finally, 50 μΙ_ Ultra TMB ELISA (Pierce catalog no. 34028) were added and plates incubated, unsealed, 5-15 min in the dark, until blue color developed. After incubation, 50 μΙ_ 2 M sulfuric acid were added to plates to top the reaction, and absorbance was determined on a Spectra ax (Molecular Devices, Sunnydale, CA) within 15 minutes at 450 nm. All washes were performed using a Bio- Tek plate washer.
The Total Rb ELISA kit (Invitrogen catalog no. KHO001 1) was used to determine the levels of total pRb. This kit uses wells precoated with a proprietary total pRb antibody for capture. All reagents listed, with the exception of cell lysate, were included in the kit. The nature of the antibodies used for capture and detection was labeled as proprietary and not disclosed. 10 μ9 of cell lysate was loaded into the wells and volume adjusted to 50 [iL with standard dilution buffer. Plates were sealed with film included in the kit and incubated for 2 h at room temperature on a shaker. Plates are then manually washed three times with 250 μί wash buffer. 50 \il of proprietary primary antibody (pre- conjugated to biotin) was added to wells and incubated for 1 h at room temperature on a shaker. Then plates were again washed as noted above. The secondary antibody (HRP pre-conjugated to Streptavidin) was diluted 1 :100 in Streptavidin-HRP diluent buffer and 50 μΙ_ was added to each well. Plates were then incubated for 30 min. Afterwards, plates were washed four times with buffer as outlined above. Finally, 50 μΙ_ stabilized Chromogen was added per well and plates were incubated for 15 min, at which point 50 pL of stop solution was added. Plates were then read on a Spectra max at 450nm. Upon quantitation of the pRb phosphorylation (p-pRb) levels, % inhibition values were derived for each concentration tested and used to determine 50% inhibitory concentrations (IC50) for a particular compound (non-normalized). The total pRb levels were then used to adjust the p-pRb % inhibition values to account for any loss of signal due to the absence of the pRb protein itself, and the IC50 values obtained from the adjusted % inhibitions represent normalized cellular p-pRb IC50.
Automated electrophysiology studies (Q-patch clamp assay)
Cell cultures: CHO cells constitutively expressing functional hERG channels were purchased from AVIVA Biosciences Corp. (San Diego, CA). Cells were grown in DMEM/F12 (Gibco Cat # 11039-021 ), supplemented with 10% FBS (Gibco Cat # 10082- 142), 1% Penicillin-Streptomycin (Gibco Cat # 15140-122) and 1% Geneticin (Gibco Cat
# 10131-027). Cells were split when they reach ~70-90% confluence by aspirating the medium from the culture and rinsing the cell monolayer with Dulbecco's PBS (Gibco Cat
# 14190-136). After removing the rinse buffer, trypsin/EDTA (0.05%, Gibco Cat # 25300- 054) was added to cover the cell monolayer and incubated for 1 minute at room temperature. Aspirate the trypsin/EDTA and leave the cells for 1 more minute. Dislodge cells from the flask by tapping the flask. Add complete medium and pipette up and down several times to mix and dissociate cell clumps until cells were separated. Count the cells and re-seed cells in flasks in 37 oC, 5.0% C02, 100% humidity incubator for passaging cells and 30°C, 5.0% C02, 100% humidity for compound screening. Before QPatch assay, growth media was removed from the culture flasks, and cells were gently rinsed with 12 ml D-PBS once. The cells were immersed in 10 ml Trypsin/EDTA (prepared freshly from 10x frozen stock with D-PBS) at room temperature for approximately 30 seconds before the solution was aspirated, then incubated for 3-4 min at 37°C. At the end the incubation, visibly rounded cells were easily dislodged from the bottom of the flask without any tap. QPatch modified storage media (CHO-S-SFM II, 25 mM HEPES, and 0.04 mg/ml soy bean trypsin inhibitor) was added and the cells were re-suspended gently by pipetting up and down 6-10 times. Cell density and viability were determined with Beckman Vicell. The cell density was adjusted to 2-3 x 106/ml in QPatch modified storage media. The cell suspension was applied to the storage container on QPatch platform immediately.
Solutions and Drugs: Cells were centrifuged (150 g, 2 min), the supernatant was removed, and the cell pellet was washed twice and finally resuspended in an extracellular solution (Na-Ringer) containing the following (in mM): 145 NaCI, 4 KCI, 2CaCI2, 1 MgCI2, 10 HEPES adjusted to pH 7.4. Aliquots (300 ul) of this suspension (3- 10 3 106 cells/ml) were transferred to the chip. The intracellular solution consisted of the following (in mM): 120 KCI, 5.374 CaCI2, 1.75 MgCI2, 10 KOH/EGTA, 10 HEPES, 5 K2- ATP adjusted to pH 7.2. Amitriptyline (reference control) was from Sigma. All compounds were prepared at 10 mM in 100% DMSO. Each concentration was made by five-fold serial dilution in 100 % DMSO, in a 96-well plate in triplicate. Each dilution was then transferred and further diluted 333-fold (testing concentration: 0.2 to 30 μΜ) in extracellular solution in a 96-well glass coated plate. The final DMSO concentration was ≤0.3 %. Electrophysiology: Ail electrophysiological experiments were conducted on a single- channel QPatch test version. The Q-plate has 16 recording chambers and each chamber has a patch clamp amplifier operating in parallel. The amplifiers are controlled by a custom-made Digital Signal Processor (DSP) board by Sophion, which performs voltage clamp of a single cell in whole-cell mode. In the hERG assay the acquisition rate of the whole-cell current during voltage protocol execution was 10 kHz. This current signal was digitally filtered with a cut-off frequency of 3 kHz (Bessel filter, order = 4). CHO-hERG Cells were held at -80 mV resting membrane potential for 100 msec and at -50 mV for 100 msec (leak subtraction), and depolarized to +20 mV for 4 sec (prepulse), followed by repolarization to -50 mV for 4 sec (test pulse) before returning to the holding potential, - 80 mV. The protocol was repeated every 20 sec. During each baseline and increased dose application period approximately 10 voltage protocols were executed.
Fluidics: Cell suspension, compound samples, and Na-Ringer (wash) in volumes of 5 - 15 μΙ were pipetted to the chips.
Data analysis: IC50 and Hill coefficient were estimated from best fits to the experimental dose-response data by the Hill equation:
Remaining current(%)=Maxl+((Mini-Maxl)/(1+((Conc./IC50)AHill))) Where axl=100, Minl=0
This fitting procedure returned values for the two variable parameters: an IC50 value and a Hill slope. Certain Examples of the present invention were evaluated in the Q-patch clamp assay.
