potent angiotensin II antagonists. In the pyrimidine carboxylic acid series (W = CR, X = N, Y = CH, Z = COOH), compounds with an alkyl group (R') on the exocyclic nitrogen were much more potent than compounds with an alkyl group (R) on the heterocyclic ring. The corresponding pyridine, pyridazine, pyrazine, and 1,2,4-triazine carboxylic acids also showed potent in vitro angiotensin II antagonism. The pyridine
人们发现,通过-CH2-NR'-连接(1)连接到联苯四唑的一系列吡啶和其他六元环杂环是有效的血管紧张素II拮抗剂。在嘧啶羧酸系列中(W = CR,X = N,Y = CH,Z = COOH),环外氮上带有烷基(R')的化合物比带有烷基(R)的化合物更有效在杂环上。相应的吡啶,哒嗪,吡嗪和1,2,4-三嗪羧酸也显示出有效的体外血管紧张素II拮抗作用。吡啶(W,X,Y = CH,Z = COOH,R'= n-C3H7)具有很强的体外活性(pA2 = 10.10,兔主动脉,Ki = 0.61 nM,大鼠肝脏中的受体结合)以及出色的口服降压活性和生物利用度。
