This invention concerns compounds of the formula I:
wherein R1 is (1-10C)alkyl, (3-8C)cycloalkyl, (3-8C)cycloalkyl-(1-4C)alkyl, phenyl or phenyl(1-4C)alkyl, the phenyl moiety of the latter two optionally bearing one or more substituents; R2 is hydrogen, (1-4C)alkyl, amino or (1-4C)-alkylamino; R6 is (1-4C)alkyl, amino or (1-4C)alkylamino; Q is a group of formula II, in which case R3 and R4 are independently hydrogen, (1-4C)alkyl, phenyl or benzyl the phenyl moiety of the latter two optionally bearing one or two substituents; R5 is hydrogen, (1-4C)alkyl or (2-4C)alkenyl; A and B are independently ethylene or trimethylene; Z is a direct bond between A and B, or an oxy, thio, carbonyl, methylene, ethylenedioxymethylene, ethylidene, or isopropylidene link, or Z is a group of the formula =N.M in which M is hydrogen, (1-6C)alkyl, phenyl or benzyl, the phenyl moiety of the latter two optionally bearing one or two substituents; or Q represents a saturated 9- or 10-membered bicyclic amino group, which is unsubstituted or is substituted by one or two substituents; and Y is a physiologically acceptable anion.
The invention also includes certain closely related anhydro-base derivatives which, like the compounds of formula I, possess beneficial effects on the cardiovascular system (and in particular beneficial effects modulated via the sino-atrial node). Also included are pharmacuetical compositions containing compounds of formula I (or a related anhydro-base) as active ingredient, and processes for the manufacture of the various novel compounds.
本发明涉及式 I 的化合物:
其中R1是(1-10C)烷基、(3-8C)环烷基、(3-8C)环烷基-(1-4C)烷基、苯基或苯基(1-4C)烷基,后两者的苯基任选带有一个或多个取代基;R2是氢、(1-4C)烷基、氨基或(1-4C)-烷基氨基;R6是(1-4C)烷基、氨基或(1-4C)烷基氨基;Q 是式 II 的基团,在这种情况下,R3 和 R4 独立地是氢、(1-4C)烷基、苯基或苄基,后两者的苯基可选择带有一个或两个取代基;R5 是氢、(1-4C)烷基或(2-4C)烯基;A 和 B 独立地是亚乙基或三亚甲基;Z 是 A 和 B 之间的直接键,或氧键、硫键、羰基键、亚甲基键、亚乙基二氧亚甲基键、亚乙基键或异亚丙基键,或 Z 是式 =N.M 的基团,其中 M 是氢、(1-4C)烷基或(2-4C)烯基。其中 M 是氢、(1-6C)烷基、苯基或苄基,后两者的苯基任选带有一个或两个取代基;或 Q 代表饱和的 9 元或 10 元双环氨基,该氨基未被取代或被一个或两个取代基取代;Y 是生理上可接受的阴离子。
本发明还包括某些密切相关的脱氢基衍生物,它们与式 I 化合物一样,对心血管系统具有有益作用(尤其是通过窦房结调节的有益作用)。此外,还包括含有式 I 化合物(或相关的氢基)作为活性成分的药用组合物,以及各种新型化合物的生产工艺。
