Discovery of CPI-1612: A Potent, Selective, and Orally Bioavailable EP300/CBP Histone Acetyltransferase Inhibitor.

ABSTRACT: The histone acetyltransferases, CREB binding protein (CBP) and EP300, are master transcriptional co-regulators that have been implicated in numerous diseases, such as cancer, inflammatory disorders, and neurodegeneration. A novel, highly potent, orally bioavailable EP300/CBP histone acetyltransferase (HAT) inhibitor, CPI-1612 or 17, was developed from the lead compound 3. Replacement of the indole scaffold of 3 with the aminopyridine scaffold of 17 led to improvements in potency, solubility, and bioavailability. These characteristics resulted in a 20-fold lower efficacious dose for 17 relative to lead 3 in a JEKO-1 tumor mouse xenograft study.

Discovery of spirohydantoins as selective, orally bioavailable inhibitors of p300/CBP histone acetyltransferases.

Project description:p300 and CREB-binding protein (CBP) are essential for a multitude of cellular processes. Dysregulation of p300/CBP histone acetyltransferase activity is linked to a broad spectrum of human diseases including cancers. A novel drug-like spirohydantoin (21) has been discovered as a selective orally bioavailable inhibitor of p300/CBP histone acetyltransferase. Lead compound 21 is more potent than the first-in-class lead A-485 in both enzymatic and cellular assays and lacks the off-target inhibition of dopamine and serotonin transporters, that was observed with A-485.

Discovery of Spiro Oxazolidinediones as Selective, Orally Bioavailable Inhibitors of p300/CBP Histone Acetyltransferases.

Project description:p300 and its paralog CBP can acetylate histones and other proteins and have been implicated in a number of diseases characterized by aberrant gene activation, such as cancer. A novel, highly selective, orally bioavailable histone acetyltransferase (HAT) domain inhibitor has been identified through virtual ligand screening and subsequent optimization of a unique hydantoin screening hit. Conformational restraint in the form of a spirocyclization followed by substitution with a urea led to a significant improvement in potency. Replacement of the hydantoin moiety with an oxazolidinedione followed by fluoro substitution led to A-485, which exhibits potent cell activity, low clearance, and high oral bioavailability.

Fragment-Based Discovery of a Selective and Cell-Active Benzodiazepinone CBP/EP300 Bromodomain Inhibitor (CPI-637).

Project description:CBP and EP300 are highly homologous, bromodomain-containing transcription coactivators involved in numerous cellular pathways relevant to oncology. As part of our effort to explore the potential therapeutic implications of selectively targeting bromodomains, we set out to identify a CBP/EP300 bromodomain inhibitor that was potent both in vitro and in cellular target engagement assays and was selective over the other members of the bromodomain family. Reported here is a series of cell-potent and selective probes of the CBP/EP300 bromodomains, derived from the fragment screening hit 4-methyl-1,3,4,5-tetrahydro-2H-benzo[b][1,4]diazepin-2-one.

Discovery of INCB3284, a Potent, Selective, and Orally Bioavailable hCCR2 Antagonist.

Project description:We report the identification of 13 (INCB3284) as a potent human CCR2 (hCCR2) antagonist. INCB3284 exhibited an IC50 of 3.7 nM in antagonism of monocyte chemoattractant protein-1 binding to hCCR2, an IC50 of 4.7 nM in antagonism of chemotaxis activity, an IC50 of 84 ?M in inhibition of the hERG potassium current, a free fraction of 58% in protein binding, high selectivity over other chemokine receptors and G-protein-coupled receptors, and acceptable oral bioavailability in rodents and primates. In human clinical trials, INCB3284 exhibited a pharmacokinetic profile suitable for once-a-day dosing (T 1/2 = 15 h).

Discovery of BIIB042, a Potent, Selective, and Orally Bioavailable ?-Secretase Modulator.

Project description:We have investigated a novel series of acid-derived ?-secretase modulators as a potential treatment of Alzheimer's disease. Optimization based on cellular potency and brain pharmacodynamics after oral dosing led to the discovery of 10a (BIIB042). Compound 10a is a potent ?-secretase modulator, which lowered A?42, increased A?38, but had little to no effect on A?40 levels both in vitro and in vivo. In addition, compound 10a did not affect Notch signaling in our in vitro assessment. Compound 10a demonstrated excellent pharmacokinetic parameters in multiple species. Oral administration of 10a significantly reduced brain A?42 levels in CF-1 mice and Fischer rats, as well as plasma A?42 levels in cynomolgus monkeys. Compound 10a was selected as a candidate for preclinical safety evaluation.

Discovery of TAK-875: A Potent, Selective, and Orally Bioavailable GPR40 Agonist.

Project description:GPR40, one of the G protein-coupled receptors predominantly expressed in pancreatic ?-cells, mediates enhancement of glucose-stimulated insulin secretion by free fatty acids. A potent and selective GPR40 agonist is theorized to be a safe and effective antidiabetic drug with little or no risk of hypoglycemia. Cyclization of the phenylpropanoic acid moiety of lead compound 1 produced fused phenylalkanoic acids with favorable in vitro agonist activities and pharmacokinetic profiles. Further optimization led to the discovery of dihydrobenzofuran derivative 9a ([(3S)-6-({2',6'-dimethyl-4'-[3-(methylsulfonyl)propoxy]biphenyl-3-yl}methoxy)-2,3-dihydro-1-benzofuran-3-yl]acetic acid hemi-hydrate, TAK-875) as a potent, selective, and orally bioavailable GPR40 agonist, with a pharmacokinetic profile enabling long-acting drug efficacy. Compound 9a showed potent plasma glucose-lowering action and insulinotropic action during an oral glucose tolerance test in female Wistar fatty rats with impaired glucose tolerance. Compound 9a is currently in clinical trials for the treatment of type 2 diabetes mellitus.

Discovery of PF-04620110, a Potent, Selective, and Orally Bioavailable Inhibitor of DGAT-1.

Project description:Acyl-CoA:diacylglycerol acyltransferase-1 (DGAT-1) catalyzes the final committed step in the biosynthesis of triglycerides. DGAT-1 knockout mice have been shown to be resistant to diet-induced obesity and have increased insulin sensitivity. Thus, inhibition of DGAT-1 may represent an attractive target for the treatment of obesity or type II diabetes. Herein, we report the discovery and characterization of a potent and selective DGAT-1 inhibitor PF-04620110 (3). Compound 3 inhibits DGAT-1 with an IC50 of 19 nM and shows high selectivity versus a broad panel of off-target pharmacologic end points. In vivo DGAT-1 inhibition has been demonstrated through reduction of plasma triglyceride levels in rodents at doses of ?0.1 mg/kg following a lipid challenge. On the basis of this pharmacologic and pharmacokinetic profile, compound 3 has been advanced to human clinical studies.
