  摘要：

  A novel series of nonpeptide angiotensin II (AII) receptor antagonists is reported, derived from linkage of the biphenylyltetrazole moiety found in previously described antagonists via a methyleneoxy chain to the 4-position of a 3-substituted 2,6-dialkylpyridine. 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 0.005-0.5 muM. A variety of substituents was found to be effective at the 3-position of the pyridine ring. On intravenous administration in a normotensive rat model, the more potent compounds inhibited the AII-induced pressor response with ED50 values in the range 0.1-1.0 mg/kg. One of the compounds, 2-ethyl-5,6,7,8-tetrahydro-4-{[2'-(1H-tetrazol-5-yl)biphenyl-4-yl]methoxy}quinoline (26), demonstrated good oral activity in two rat models. At doses in the range 1-10 mg/kg po in AII-infused, conscious, 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 26 showed a rapid and sustained lowering of blood pressure at a dose of 5 mg/kg po. Based on its profile, this compound, designated ICI D6888, has been selected for evaluation in volunteers.

  Three-dimensional substructure searching (3D search), using the program MACCS-3D, was utilized for designing novel angiotensin II receptor antagonists which contain a bioisostere of the biphenylyltetrazole moiety of DuP 753. A 3D query was prepared from an overlay model of substructures of several potent AII antagonists. The search system retrieved 139 compounds from the database MDDR-3D, which consisted
