This invention concerns compounds of the formula I: ##STR1## wherein R.sup.1 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; R.sup.2 is hydrogen, (1-4C)alkyl, amino or (1-4C)alkylamino; R.sup.6 is (1-4C)alkyl, amino or (1-4C)alkylamino; Q is a group of formula II, in which case R.sup.3 and R.sup.4 are independently hydrogen, (1-4C)alkyl, phenyl or benzyl the phenyl moiety of the latter two optionally bearing one or two substituents; R.sup.5 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 .dbd.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 pharmaceutical compositions containing compounds of formula I (or a related anhydro-base) as active ingredient, and processes for the manufacture of the various novel compounds.
本发明涉及公式I的化合物:##STR1## 其中R.sup.1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,后两者的苯基部分可以选择性地带有一个或多个取代基;R.sup.2是氢,(1-4C)烷基,氨基或(1-4C)烷基氨基;R.sup.6是(1-4C)烷基,氨基或(1-4C)烷基氨基;Q是公式II的一个基团,在这种情况下,R.sup.3和R.sup.4独立地是氢,(1-4C)烷基,苯基或苄基,后两者的苯基部分可以选择性地带有一个或两个取代基;R.sup.5是氢,(1-4C)烷基或(2-4C)烯基;A和B独立地是乙烯或三亚甲基;Z是A和B之间的直接键,或氧,硫,羰基,亚甲基,乙二醇二甲醚基,乙基亚甲基,或异丙基亚甲基链,或Z是公式.dbd.N.M的一个基团,在这种情况下,M是氢,(1-6C)烷基,苯基或苄基,后两者的苯基部分可以选择性地带有一个或两个取代基;或Q表示未取代或取代了一个或两个取代基的饱和的9-或10-成员的双环氨基基团;Y是一种生理上可接受的阴离子。本发明还包括某些密切相关的无水碱基衍生物,类似于公式I的化合物,对心血管系统具有有益的影响(特别是通过窦房结调节的有益影响)。还包括含有公式I(或相关的无水碱基)化合物作为活性成分的药物组成物,以及制造各种新化合物的过程。
