  Triazolinones as nonpeptide angiotensin II antagonists. 1. Synthesis and evaluation of potent 2,4,5-trisubstituted triazolinones

  摘要：

  A series of 2,4-dihydro-2,4,5-trisubstituted-3H-1,2,4-triazol-3-ones was prepared via several synthetic routes and evaluated as AII receptor antagonists in vitro and in vivo. The preferred compounds contained a [2'-(5-tetrazolyl)biphenyl-4-yl]methyl side chain at N4 and an n-butyl group at C5. A number of these bearing an alkyl or aralkyl substituent at N2 showed in vitro potency in the nanomolar range (rabbit aorta membrane receptor), and several of these, e.g., the 2,2-dimethyl-1-propyl analogue (54, IC50 = 2.1 nM), effectively blocked the AII pressor response in conscious rats with significant duration (2.5 h at 1 mg/kg orally for 54). Among analogues possessing aryl substituents at N2, ortho substitution on the phenyl moiety resulted in several derivatives with in vitro potency in the low nanomolar range. One of these, featuring a 2-(trifluoromethyl)phenyl substituent at N2 (25, IC50 = 1.2 nM), was effective at 1 mg/kg orally in the rat model, with a duration of >6 h. Implications for hydrophobic and hydrogen-bonding interactions with the AT1 receptor are discussed.

  摘要：

  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。

  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
