DIHYDROPYRROLOPYRIMIDINE DERIVATIVES

FIELD OF THE INVENTION

The present invention relates to novel dihydropyrrolopyrimidine derivatives that are useful in the treatment of abnormal cell growth, such as cancer, in mammals. The present invention also relates to pharmaceutical compositions containing the compounds and to methods of using the compounds and compositions in the treatment of abnormal cell growth in mammals.

BACKGROUND

Phosphoinositide 3-kinases (“PI3Ks”) comprise a family of lipid kinases that catalyze the synthesis of the phosphatidylinositol (“PI”) second messagers PI(3)P (“PIP”), PI(3,4)P₂(“PIP₂”), and PI(3,4,5)P₃(“PIP₃”). (Fruman et al., “Phosphoinositide kinases”, Annu. Rev. Biochem. 67 (1998), pp. 481-507; Knight et al., “A Pharmacological Map of the PI3-K Family Defines a Role for p110α in Insulin Signaling”, Cell 125 (2006), pp. 733-747.) In the appropriate cellular context, these lipids mediate diverse physiological processes including cell growth, survival, differentiation, and chemotaxis. (Katso et al., “Cellular function of phosphoinositide 3-kinases: implications for development, homeostasis, and cancer”, Annu. Rev. Cell Dev. Biol. 17 (2001), pp. 615-675.) The PI3K family comprises at least 15 different lipid and serine/threonine kinases, sub-classified by structural homology, with distinct substrate specificities, expression patterns, and mode of regulation. Class I PI3Kα is the main PI3-kinase isoform in cancer, and consists of catalytic (p110α) and adapter (p85) subunits. (Stirdivant et al., “Cloning and mutagenesis of the p110α subunit of human phosphoinositide 3′-hydroxykinase”, Bioorg. Med. Chem. 5 (1997), pp. 65-74.) The 3-phosphorylated phospholipid, PIP₃, acts as a second messenger recruiting kinases with lipid binding domains (including plekstrin homology (“PH”) regions), such as Akt, the product of the human homologue of the viral oncogene v-Akt, and phosphoinositide-dependent kinase-1 (“PDK1”). (Vivanco & Sawyers, “The Phosphatidylinositol 3-Kinase-Akt Pathway In Human Cancer”, Nature Reviews Cancer 2 (2002), pp. 489-501.) Binding of Akt to PIP₃induces Akt to translocate to the plasma membrane, bringing Akt into contact with PDK1, which activates Akt. The tumor-suppressor phosphatase, PTEN, dephosphorylates PIP₃, and therefore acts as a negative regulator of Akt activation. The PI3Ks, Akt and PDK1 are important in the regulation of many cellular processes including cell cycle regulation, proliferation, survival, apoptosis and motility and are significant components of the molecular mechanisms of diseases such as cancer, diabetes and immune inflammation. Functional loss of PTEN (the most commonly mutated tumor-suppressor gene in cancer after p53), oncogenic mutations in the PIK3CA gene encoding PI3Kα, amplification of the PIK3CA gene and overexpression of Akt have been established in many malignancies. (see, for example, Samuels, et al., “High frequency of mutations of the PIK3CA gene in human cancers”, Science 304 (2004), p. 554; Broderick et al., “Mutations in PIK3CA in anaplastic oligodendrogliomas, high-grade astrocytomas, and medulloblastomas”, Cancer Research 64 (2004), pp. 5048-5050.) Therefore, the deregulation of PI3k and the upstream and downstream components of this signaling pathway is one of the most common deregulations associated with human cancers and proliferative diseases. (Parsons et al., Nature, 436 (2005), p. 792; Hennessey et al., Nature Rev. Drug Disc. 4 (2005) 988-1004.)

PI3Kα is thus an attractive target for cancer drug development because PI3Kα inhibitors would be expected to inhibit proliferation and summon resistance to cytotoxic agents in cancer cells.

Compounds described herein containing one or more asymmetric carbon atoms can exist as two or more stereoisomers. Where a compound described herein contains an alkenyl or alkenylene group, geometric cis/trans (or Z/E) isomers are possible. Where structural isomers are interconvertible via a low energy barrier, tautomeric isomerism (‘tautomerism’) can occur. This can take the form of proton tautomerism in compounds described herein containing, for example, an imino, keto, or oxime group, or so-called valence tautomerism in compounds which contain an aromatic moiety. A single compound may exhibit more than one type of isomerism.

Included within the scope of the present embodiments are all stereoisomers, geometric isomers and tautomeric forms of the compounds described herein, including compounds exhibiting more than one type of isomerism, and mixtures of one or more thereof. Also included within the scope of the present embodiments are rotational isomers (rotamers). For example, certain compounds, including certain amides and carbamates are rotational isomers by 1H NMR at room temperature. The rotamer peaks coalesce if an NMR is taken at 80° C. Further included are acid addition or base salts wherein the counterion is optically active, for example, d-lactate or 1-lysine, or racemic, for example, dl-tartrate or dl-arginine.

Cis/trans isomers may be separated by conventional techniques well known to those skilled in the art, for example, chromatography and fractional crystallisation.

Conventional techniques for the preparation/isolation of individual enantiomers include chiral synthesis from a suitable optically pure precursor or resolution of the racemate (or the racemate of a salt or derivative) using, for example, chiral high pressure liquid chromatography (HPLC) or SFC.

Alternatively, the racemate (or a racemic precursor) may be reacted with a suitable optically active compound, for example, an alcohol, or, in the case where a compound described herein contains an acidic or basic moiety, a base or acid such as 1-phenylethylamine or tartaric acid. The resulting diastereomeric mixture may be separated by chromatography and/or fractional crystallization and one or both of the diastereoisomers converted to the corresponding pure enantiomer(s) by means well known to a skilled person.

Enzyme Production for Biochemical Assays:

1) PI3Kα Complex (Full Length p110α and p85α)(“PI3KA_FL”)

Genes encoding for full length p110α and p85α subunits of PI3Kα complex were subcloned from existing constructs into pFASTBAC Dual vector (Life Technologies, Carlsbad, Calif.) using standard cloning procedures. Gene encoding p110α subunit was subcloned into polyhedrine promoter while gene encoding p85α subunit was subcloned into p10 promoter. Additionally, sequence encoding for histidine tag and Tobacco Etch Virus (“TEV”) cleavage site preceded p110α ORF (Open Reading Frame). Recombinant baculovirus was generated using Bac-to-Bac protocol (Life Technologies, Carlsbad, Calif.) and large scale expression was conducted in Sf21 (Life Technologies, Carlsbad, Calif.) cells at a multiplicity of infection (“MOI”)=1 for 72 hours. Cells were lyzed in 50 mM Tris pH 8.0, 250 mM NaCl, 5% glycerol, 0.25 mM TCEP, and 20 mM imidazole. The PI3Kα complex was purified from clarified supernatant using Immobilized Metalo Affinity Chromatography (“IMAC”). The protein was eluted from the column using 50 mM Tris pH 8.0, 200 mM NaCl, 5% glycerol, 0.25 mM TCEP, and 200 mM imidazole, and further desalted into 50 mM Tris pH 8.0, 20 mM NaCl, and 0.25 mM TCEP prior to loading on MonoQ sepharose (GE Healthcare, Piscataway, N.J.). PI3Kα complex was eluted from MonoQ sepharose over 20 column volumes using 0-30% gradient of buffer B (50 mM Tris pH 8.0, 1 M NaCl, and 0.25 mM TCEP). The peak fractions were pulled together and loaded on Superdex 200 26/60 SEC column equilibrated in 50 mM Tris pH 8.0, 200 mM NaCl, and 0.5 mM TCEP. Following SEC, chromatography peak fractions were pulled and concentrated to 1.87 mg/mL. Purity and integrity of the complex was confirmed using LCMS, analytical SEC and SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis) analysis.

2) p110α-iSH2 p85α Complex (Full Length p110α and p85α iSH2)(“PI3KA_Act”)

Genes encoding for full length p110α and p85α nSH-iSH2=niSH2 (p85a aminoacids 322-600) subunits of PI3Kα complex were subcloned from existing constructs into pFASTBAC Dual vector (Life Technologies, Carlsbad, Calif.) using standard cloning procedures. Gene encoding p110α subunit was subcloned into polyhedrine promoter while gene encoding p85α niSH2 domains was subcloned into p10 promoter. Additionally, Human Rhinovirus 3C Protease (“HRV 3C”) site was introduced between nSH2 and iSH2, replacing aminoacids 431-438 of p85α with LEVLFQGP HRV 3C recognition sequence, using standard QuickChange mutagenesis protocol (Agilent Technologies, CA). Recombinant baculovirus was generated using Bac-to-Bac protocol (Life Technologies, Carlsbad, Calif.). Large scale expression was conducted in Sf21 (Life Technologies, Carlsbad, Calif.) cells at a multiplicity of infection (“MOI”)=1 for 48 hours. Cells were lyzed in 50 mM Tris pH 8.0, 250 mM NaCl, 5% glycerol, 0.25 mM TCEP, and 20 mM imidazole. The p110α-niSH2 p85α complex was purified from clarified supernatant using Immobilized Metalo Affinity Chromatography (“IMAC”). The protein was eluted from the column using 50 mM Tris pH 8.0, 200 mM NaCl, 0.25 mM TCEP, and 200 mM imidazole. Following elution p110α-niSH2 p85α complex was dialyzed against 4 liters of 50 mM Tris pH 8.0, 200 mM NaCl, 0.25 mM TCEP, and 40 mM imidazole in the presence of PreScission Protease (1:70 molar ratio of Protease to Protein) and TEV protease (1:40 molar ratio protease to protein) for 16 hours at 4° C. The protein was further purified using reverse IMAC to remove cleaved histidine tag and contaminants captured during initial IMAC purification. The mixture of p110α-iSH2 p85α complex and cleaved nSH2 was recovered in reverse IMAC 40 mM imidazole flow through and 60 mM imidazole wash fractions. Those fractions were pulled together and loaded on Superdex 200 26/60 SEC column equilibrated in 25 mM Tris, pH 8.0, 100 mM NaCl, 2% glycerol, and 2 mM TCEP. Following SEC, chromatography peak fractions containing p110α-iSH2 p85α complex were pulled and concentrated to 4.3 mg/mL. Purity and integrity of the complex was confirmed using LCMS, analytical SEC and SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis) analysis.

Biochemical Assays

The biochemical assays of kinase activity of full-length PI3Kα (full-length p110α/p85a) or truncated PI3Kα (p110α/iSH2 p85a) were conducted using a fluorescence polarization format similar to the procedure of Yuan J., et al., (2011) “PF-04691502, a Potent and Selective Oral Inhibitor of PI3K and mTOR Kinases with Antitumor Activity”, Mol Cancer Ther. 10, 2189-2199. The enzymatic reactions were conducted in 50 μL volumes in 96-well plates. The reactions contained human recombinant PI3Kα (2 nM full-length p110α/p85α or 0.5 nM p110α/iSH2 p85) and 30 μM phosphatidylinositol 4,5-bisphosphate (“PIP2”) (Cayman Chemical Company, Ann Arbor, Mich.) and were sonicated for 1 minute prior to adding PI3Kα enzyme (PI3KA_Act or PI3KA_FL), DMSO or test compound (12-point 3-fold serial dilution, 3 μM top dose, 2° A) DMSO final concentration), 5 mM MgCl₂, 50 mM HEPES pH 7.4, 150 mM NaCl, 1 mM DTT ((2S,3S)-1,4-bis(sulfanyl)butane-2,3-diol), and 0.05% 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate (“CHAPS”). The reactions were initiated by the addition of ATP (41 μM, ˜Km-level, for full-length p110α/p85 or 1 mM ATP for p110α/iSH2 p85), following a 15-min preincubation. The reactions were incubated for 30 min at room temperature, stopped with EDTA pH 8 (10 mM final concentration). In a detection plate, 15 μL of detector/probe mixture, containing 480 nM GST-Grp1 PH domain protein (University of Dundee, Dundee, UK) and 12 nM carboxytetramethylrhodamine (“TAMRA”)-tagged fluorescent phosphatidylinositol (3,4,5)-triphosphate (“PIP3”) (Echelon Biosciences, Inc., Salt Lake City, Utah) in assay buffer, was mixed with 15 μL of kinase reaction mixture. The plate was shaken for 30 minutes and fluorescence polarization values were measured on an LJL Analyst HT plate reader (Molecular Devices, Sunnyvale, Calif.). The inhibitors were shown to be ATP-competitive from kinetic and crystallographic studies. The inhibition constants (Ki) were calculated by fitting fluorescence polarization values, corresponding to initial reaction rates, to the Morrison equation (Morrison, J. F. (1969) Kinetics of the reversible inhibition of enzyme catalysed reactions by tight-binding inhibitors. Biochim. Biophys. Acta 185, 269-286) for tight-binding competitive inhibitors using non-linear regression method (GraphPad Prism, GraphPad Software, San Diego, Calif.).

The results of the biological assays for the compounds tested are listed in Table 4.
