The synthesis and coronary vasodilating and antihypertensive activities of 1,2,4-triazolo[1,5-a]pyrimidines fused to pyrrole, thiophene, pyran, pyridine, and pyridazine are described. Among these compounds, 8-tert-butyl-7,8-dihydro-5-methyl-6H-pyrrolo[3,2-e][1,2,4]triazolo[1,5-a]pyrimidine (23) was found to be the most promising potential cardiovascular agent, having been shown to be more potent in
描述了与吡咯,噻吩,吡喃,吡啶和哒嗪融合的1,2,4-三唑并[1,5-a]嘧啶的合成及其冠状血管舒张和降压活性。在这些化合物中,8-叔丁基-7,8-二氢-5-甲基-6H-吡咯并[3,2-e] [1,2,4]三唑并[1,5-a]嘧啶(23)为被发现是最有前途的潜在心血管疾病药物,已被证明比特拉迪尔[7-二乙基氨基)-5-甲基-1,2,4-三唑并[1,5-a]嘧啶具有更强的冠脉扩张活性,降压活性与硫酸胍乙当量相当。
