Cardiovascular disturbances and the effects of histamine and excessive gastric secretion can be countered by compounds expressed generally by the formula:
wherein;
p is zero, one or two;
m is one to six inclusive;
A is hydrogen, -O-R1, -C=N, -(O)NR1R2, -C(O)R1, -C(O)-OR1, -CH2OR1, -CH2NR1R2, or -OC(O)R1; Q is
d and n are zero or one and the dotted lines represent double bonds which may form consistent with the valence of carbon;
B is
Ar, D and R are selected from phenyl and substituted phenyl with certain limitations, pyrldinyl, thienyl, furanyl or naphthyl and, in addition, R may have the values: benzyl, substituted benzyl, cycloalkyl or loweralkyl, and D may additionally have the values: 2H-1-benzopyran-2-one, 4-oxo-4H-1-benzopyran-2-carboxylic acid loweralkyl ester, 1,4-benzodioxanloweralkyl-2-yl or quinolinyl, and the pharmaceutically acceptable addition salts thereof.
心血管紊乱以及组胺和胃液分泌过多的影响可由一般由式表示的化合物来抵消:
其中
p 为 0、1 或 2;
m 是 1 至 6(包括 6);
A 是氢、-O-R1、-C=N、-(O)NR1R2、-C(O)R1、-C(O)-OR1、-CH2OR1、-CH2NR1R2 或 -OC(O)R1; Q 是
d 和 n 为 0 或 1,虚线表示可能形成的与碳价位一致的双键;
B 是
Ar、D 和 R 选自苯基和有一定限制的取代苯基、吡啶基、噻吩基、呋喃基或萘基,此外,R 可具有以下值:苄基、取代苄基、环烷基或低级烷基,D 可具有以下值:2H-1-苯并吡喃-2-酮、4-氧代-4H-1-苯并吡喃-2-羧酸低级烷基酯、1,4-苯并二恶烷低级烷基-2-基或喹啉基,以及它们的药学上可接受的加成盐。
