Abstract
We have previously reported the identification of pyrazole-5-carboxylic acids as a new class of endothelin antagonists from low affinity pyrazol-5-ol ligands, which were obtained by random screening assays. We describe herein the synthesis and the structure activity relationships (SARs) of these pyrazole-5-carboxylic acids with potent ET(A) selective, mixed ET(A)/ET(B) or moderately ET(B) selective antagonist activities.
