  New nonpeptide angiotensin II receptor antagonists. 2. Synthesis, biological properties, and structure-activity relationships of 2-alkyl-4-(biphenylylmethoxy)quinoline derivatives

  摘要：

  A novel series of nonpeptidic angiotensin II (AII) receptor antagonists is reported, derived from linkage of the biphenylcarboxylic acid or biphenylyltetrazole moiety found in previously described antagonists via a methyleneoxy chain to the 4-position of a 2-alkyl quinoline. When evaluated in an in vitro binding assay using a guinea pig adrenal membrane preparation, compounds in this series generally gave IC50 values in the range 0.01-1 muM. Structure-activity studies showed the quinoline nitrogen atom and a short alkyl chain at the quinoline 2-position to be essential for receptor binding. On intravenous administration in a normotensive rat model, the more potent compounds inhibited the AII-induced pressor response with ED50 values in the range 0.1-2.0 mg/kg. One of the compounds, 2-ethyl-4-[[2'-(1H-tetrazol-5-yl)biphenyl-4-yl]methoxy]quinoline (5g), demonstrated good oral activity in two rat models. At doses in the range 1-10 mg/kg in AII-infused, normotensive rats, the compound exhibited a dose-related inhibition of the pressor response with a good duration of action at the higher doses. In a renal hypertensive rat model, compound 5g showed a rapid and sustained lowering of blood pressure at a dose of 5 mg/kg. On the basis of its profile, this compound, designated ICID8731, has been selected for clinical evaluation.
