publication. Structure-activity studies showed that a variety of substituents are tolerated on the dihydropyrimidine ring, indicating that the AII receptor is permissive in accepting this region of the nonpeptide antagonists. As reported for imidazole-based AII antagonists, the tetrazolyl dihydropyrimidine analogs were found to be more potent than the corresponding carboxylic acids. Our studies show that
以前称为DuP 753的非肽血管紧张素II(AII)受体拮抗剂洛沙坦的发现引起了人们对该合成新类似物的兴趣。我们在这一领域的努力已导致发现二氢嘧啶作为有效的AII受体拮抗剂。在该出版物中报道了导致这种新型AII拮抗剂的化学及其生物学特性。结构活性研究表明,在二氢嘧啶环上可以耐受多种取代基,这表明AII受体可以接受该非肽拮抗剂区域。如基于咪唑的AII拮抗剂的报道,发现四唑基二氢嘧啶类似物比相应的羧酸更有效。我们的研究表明,二氢嘧啶类似物2-丁基-4-氯-1,6-二氢-6-甲基-1-[[2'-(1H-四唑-5-基)[1,1'-联苯] -4 -基]甲基]嘧啶-5-羧酸乙酯(Ki = 8.3 nM),2-丁基-4-氯-1,6-二氢-6-甲基-1-[[[2'-(1H-四唑) -5-基)[1,1'-联苯] -4-基]甲基] -5-嘧啶羧酸(Ki = 1.0 nM)和2-丁基-6-氯-1,4-二氢-4,4
