  Selective ET_A Antagonists. 5. Discovery and Structure−Activity Relationships of Phenoxyphenylacetic Acid Derivatives

  摘要：

  The fifth paper in this series describes the culmination of our investigations into the development of a potent and selective ETA receptor antagonist for the treatment of diseases mediated by ET-1. Receptor site mapping of several ETA antagonists prepared previously identified a common cationic binding site which prompted synthesis of phenoxyphenylacetic acid derivative 13a, which showed good in vitro activity (IC50 59 nM, rat aortic ETA). Optimization of 13a led to the identification of 27b, which exhibited an IC50 of 4 nM. Although this did not translate into the expected in vivo potency, a compound of comparable in vitro activity, 27a (RPR118031A), showed a far better pharmacokinetic profile and in vivo potency (75 mu mol/kg) and was duly proposed and accepted as a development candidate.

  The third in this series of papers describes our further progress into the discovery of a potent and selective endothelin A (ETA) receptor antagonist for the potential treatment of diseases in which a pathophysiological role for endothelin has been implicated. These include hypertension, ischemic diseases, and atherosclerosis. In earlier publications we have outlined the discovery and structure-activity relations of two moderately potent series of nonpeptide ETA receptor antagonists. In this paper, we describe how a pharmacophore model for ETA receptor binding was developed which enabled these two series of compounds to be merged into a single class of 4-phenoxybutanoic acid derivatives. The subsequent optimization of in vitro activity against the ETA receptor led to the discovery of (R)-4-[2-cyano-5-(3-pyridylmethoxy)phenoxy]-4-(2-methylphenyl)butanoic acid (12m). This compound exhibits low-nanomolar binding to the ETA receptor and a greater than 1000-fold selectivity over the ETB receptor. Data are presented to demonstrate that 12m is orally bioavailable in the rat and is a functional antagonist in vitro and in vivo of ET-1-induced vasoconstriction.
