New 2-arylimidazopyridines of the general formula I ##STR1## wherein --A.dbd.B-- is (a) --CH.dbd.N-- or (b) N.dbd.CH--, Ar is a phenyl radical, which, in case (a), is substituted by one or two alkynyloxy, cyanomethoxy, carboxymethoxy, and/or alkyloxycarbonylmethoxy groups, and can be substituted by one or two additional hydroxyl, alkyloxy, alkenyloxy and/or alkynyloxy groups, or which in case (b), is substituted by one to three hydroxyl, mercapto, and/or --Z--R groups, Z is --O--, --S-- or --SO-- and R is alkyl, alkenyl, alkynyl, hydroxyalkyl, cyanomethyl, carboxymethyl or alkyloxycarbonylmethyl, the alkyl, alkenyl, alkynyl and hydroxyalkyl groups each having up to 5 C atoms, but wherein in case (b), the phenyl radical is only substituted by hydroxyl or methoxy groups if it has at the same time at least one other substituent differing from these, and their physiologically acceptable salts show positive inotropic effects.
通式I表示的是新的2-芳基咪唑吡啶类化合物,其中--A.dbd.B--是(a) --CH.dbd.N--或者(b) N.dbd.CH--,Ar是苯基,如果是情况(a),则被一个或两个炔氧基、氰甲氧基、羧甲氧基和/或烷氧羰基甲氧基取代,还可以被一个或两个额外的羟基、烷氧基、烯氧基和/或炔氧基取代;如果是情况(b),则被一个到三个羟基、巯基和/或--Z--R基取代,Z是--O--、--S--或--SO--,R是烷基、烯基、炔基、羟基烷基、氰甲基、羧甲基或烷氧羰基甲基,其中烷基、烯基、炔基和羟基烷基的碳原子数均不超过5个,但是在情况(b)中,如果苯基同时具有至少一个与这些不同的取代基,则只能被羟基或甲氧基取代,它们的生理上可接受的盐具有正性肌力作用。
