  Discovery of (3S,3aR)-2-(3-Chloro-4-cyanophenyl)-3-cyclopentyl-3,3a,4,5-tetrahydro-2H-benzo[g]indazole-7-carboxylic Acid (PF-3882845), an Orally Efficacious Mineralocorticoid Receptor (MR) Antagonist for Hypertension and Nephropathy

  摘要：

  We have discovered a novel class of nonsteroidal pyrazoline antagonists of the mineralocorticoid receptor (M R) that show excellent potency and selectivity against other nuclear receptors. Early analogues were poorly soluble and had a propensity to inhibit the hERG channel. Remarkably, both of these challenges were overcome by incorporation of a single carboxylate moiety. Structural modification of carboxylate-containing lead R-4g with a wide range of substituents at each position of the pyrazoline ring resulted in R-12o, which shows excellent activity against MR and reasonable pharmacokinetic profile. Introduction of conformational restriction led to a novel series characterized by exquisite potency and favorable steroid receptor selectivity and pharmacokinetic profile. Oral dosing of 3S,3aR-27d (PF-3882845) in the Dahl salt sensitive preclinical model of salt-induced hypertension and nephropathy showed blood pressure attenuation significantly greater than that with eplerenone, reduction in urinary albumin, and renal protection. As a result of these findings, 3S,3aR-27d was advanced to clinical studies.

  and improving biopharmaceutical properties. From this effort, (R)-14c was identified as a potent nonsteroidal MR antagonist (IC50 = 4.5 nM) with higher than 500-fold selectivity versus PR and other related nuclear hormone receptors, with improved solubility as compared to 2 and pharmacokinetic properties suitable for oral administration. (R)-14c was evaluated in vivo using the increase of urinary Na+/K+
