  Selective endothelin A receptor ligands. 1. Discovery and structure-activity of 2,4-disubstituted benzoic acid derivatives

  摘要：

  This paper describes the discovery of a new non-peptide endothelin A (ETA) selective ligand, 2,4-dibenzyloxybenzoic acid 3, which inhibits the binding of [I-125]ET-1 to ETA receptors with an IC50 of 9 mu M (ET-1 = endothelin-1). Optimisation of 3 resulted in compound 52 which had an IC50 of 1 mu M. One of the analogues of 3, compound 15, was examined in a functional assay and shown to antagonise ET-1-induced contraction of rat aorta. The identification of 3 was made through the application of ChemDBS-3D searching of our corporate database. The 3D query, using an aromatic ring to a carboxylic acid group separated by 10.2 +/- 1.1 Angstrom, was derived from an examination of common pharmacophoric distances found in the low energy conformations of two known ETA antagonists, the cyclic pentapeptide BQ 123 1 and myriceron caffeoyl ester 2.
