To improve water solubility and to studystructure-activityrelationships, we modified the structure of the pyrimidine nucleus of each of a series of potent ET(A) antagonists, 3a and 4a, at the 2-position. In a previous study, each of these antagonists showed an extremely high affinity for the ET(A) receptor in porcine aortic membrane (IC(50) 3a; < 0.001 nM, 4a; 0.0039 nM). Two modification methods
