专利号:WO-9314086-A1 优先权日:1992-01-17 标 题 :Substituted 1-isoquinolone derivatives as angiotensin ii antagonists 发明人:FISHER LAWRENCE E; CAROON JOAN M; STABLER STEPHEN R; CLARK ROBIN D 权利人:SYNTEX INC 摘要:1-Isoquinolone derivatives and related compounds according to formula (I) wherein, Y is selected from the group consisting of H, OH, lower alkoxy, and halo; X is selected from the group consisting of H, lower alkyl acid, lower alkyl ester, and lower alkyl; and R1 is selected from the group consisting of H, alkenyl, lower alkyl, lower cycloalkyl, unsubstituted or substituted 3-spiro-1H-indane of structure (II) wherein R2 is H, OH, lower alkyl, lower alkoxy or halo, and 3-spiro-cycloalkyl of structure (III) wherein n is an integer from zero to six, provided that when R1 is spiro- X is H, or a pharmaceutically acceptable salt thereof, with the proviso that when R1 is spiro-, X is H, and when R1 is H, alkenyl, lower alkyl or lower cycloalkyl substituted at the 3-position of the isoquinolone moiety and X is H or lower alkyl, the (2'-1H--tetrazol-5-yl)biphenyl-4'-ylmethyl group cannot be at the 2(N) position, are useful as angiotensin II receptor antagonists. Also disclosed are methods of synthesis, intermediates, pharmaceutical formulations and methods of treatment.
