  Discovery of a potent and selective small molecule hGPR91 antagonist

  摘要：

  GPR91, a 7TM G-Protein-Coupled Receptor, has been recently deorphanized with succinic acid as its endogenous ligand. Current literature indicates that GPR91 plays role in various pathophysiology including renal hypertension, autoimmune disease and retinal angiogenesis. Starting from a small molecule high-throughput screening hit 1 (hGPR91 IC(50): 0.8 mu M)-originally synthesized in Merck for Bradykinin B(1) Receptor (BK(1)R) program, systematic structure-activity relationship study led us to discover potent and selective hGPR91 antagonists e.g. 2c, 4c, and 5g (IC(50): 7-35 nM; >1000 fold selective against hGPR99, a closest related GPCR; > 100 fold selective in Drug Matrix screening). This initial work also led to identification of two structurally distinct and orally bio-available lead compounds: 5g (%F: 26) and 7e (IC(50): 180 nM; > 100 fold selective against hGPR99; %F: 87). A rat pharmacodynamic assay was developed to characterize the antagonists in vivo using succinate induced increase in blood pressure. Using two representative antagonists, 2c and 4c, the GPR91 target engagement was subsequently demonstrated using the designed pharmacodynamic assay. (C) 2011 Elsevier Ltd. All rights reserved.

  Antagonism of alpha(v)beta(6) is emerging as a potential treatment of idiopathic pulmonary fibrosis based on strong target validation. Starting from an alpha(v)beta(3) antagonist lead and through simple variation in the nature and position of the aryl substituent, the discovery of compounds with improved alpha(v)beta(6) activity is described. The compounds also have physicochemical properties commensurate with oral bioavailability and are high quality starting points for a drug discovery program. Compounds 33S and 43E1 are pan av antagonists having ca. 100 nM potency against alpha(v)beta(3), alpha(v)beta(5), alpha(v)beta(6), and av beta 8 in cell adhesion assays. Detailed structure activity relationships with these integrins are described which also reveal substituents providing partial selectivity (defined as at least a 0.7 log difference in pIC(50) values between the integrins in question) for alpha(v)beta(3) and alpha(v)beta(5).
