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 shown positive inotropic effects.
一般式I的新2-芳基
咪唑吡啶,其中--A.dbd.B--为(a) --CH.dbd.N--或(b) N.dbd.CH--,Ar为苯基,其中在情况(a)中,被一个或两个炔氧基,
氰甲氧基,羧甲氧基和/或烷氧羰甲氧基基团取代,并且可以被一个或两个额外的羟基,烷氧基,烯氧基和/或炔氧基基团取代,或者在情况(b)中,被一个到三个羟基,巯基和/或--Z--R基团取代,其中Z为--O--,--S--或--SO--,而R为烷基,烯基,炔基,羟基烷基,
氰甲基,羧甲基或烷氧羰甲基,烷基,烯基,炔基和羟基烷基基团每个具有高达5个C原子,但在情况(b)中,苯基只有在同时具有至少一种与这些不同的其他取代基时才被羟基或甲氧基基团取代,并且它们的生理上可接受的盐呈现正肌力作用。
