This invention concerns novel aminopyrimidinium salts of the formula I: ##STR1## in which R.sup.1 is alkyl, alkenyl, cycloalkyl, phenyl, phenylalkyl or cycloalkyl-alkyl; one of R.sup.2 and R.sup.6 is a basic group selected from amino, alkylamino, dialkylamino of up to eight carbon atoms, pyrrolidino, piperidino and morpholino; and the other of R.sup.2 and R.sup.6 is hydrogen, alkyl, alkenyl, alkoxyalkyl, phenyl, phenylalkyl, cycloalkyl or cycloalkyl-alkyl; or both of R.sup.2 and R.sup.6 are basic groups as mentioned above; and R.sup.5 is hydrogen, (1-4C)alkyl or (3-6C)alkenyl; or R.sup.2 is a basic group as mentioned above, and R.sup.5 and R.sup.6 together form alkylene or, together with the appendant carbon atoms of the pyrimidine ring, complete a benzene ring; R.sup.4 is hydrogen, alkyl, cycloalkyl-alkyl, alkenyl, alkynyl or phenylalkyl; or R.sup.4 is an optionally substitutued alkylene or alkenylene linked to the nitrogen atom of the group Q.A.N--, either of which linking groups may thereby completing a ring including two adjacent carbon atoms of Q, the carbon atoms of A and the adjacent nitrogen atom of the group --A.N--; A is a direct bond to the the group --N(R.sup.4)-- or is alkylene or oxyalkylene; Q is a pyridyl, furyl, thienyl or phenyl moiety; and Y is a physiologically acceptable anion; but excluding a number of compounds specified hereinafter. The invention also includes certain closely related anhydro-base derivatives which, like the formula I compounds, possess beneficial effects on the cardiovascular system (and in particular beneficial effects modulated via the sino-atrial node). Also included are pharmaceutical compositions containing the formula I compound (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的新型氨基嘧啶盐:##STR1## 其中R.sup.1是烷基,烯基,环烷基,苯基,苯基烷基或环烷基-烷基; R.sup.2和R.sup.6中的一个是从氨基,碳数不超过八个的烷基氨基,二烷基氨基,吡咯烷基,哌啶基和吗啉中选择的碱性基团; 另一个是氢,烷基,烯基,烷氧基烷基,苯基,苯基烷基,环烷基或环烷基-烷基; 或者R.sup.2和R.sup.6都是上述的碱性基团; R.sup.5是氢,(1-4C)烷基或(3-6C)烯基; 或者R.sup.2是上述的碱性基团,而R.sup.5和R.sup.6共同形成烷基ene或与嘧啶环的附加碳原子一起形成苯环; R.sup.4是氢,烷基,环烷基-烷基,烯基,炔基或苯基烷基; 或者R.sup.4是可选取代的烷基ene或烯基ene,连接到Q.A.N-的氮原子,其中任何一个连接基团可以包括Q的相邻碳原子之一和相邻氮原子的碳原子,A的碳原子和-A.N-基团的相邻氮原子,从而形成一个环; A是直接键到-N(R.sup.4)-基团的键合或烷基ene或氧烷基ene; Q是吡啶基,呋喃基,噻吩基或苯基基团; Y是生理上可接受的阴离子; 但不包括下面指定的一些化合物。本发明还包括某些密切相关的无水基衍生物,像公式I化合物一样,在心血管系统上具有有益的作用(特别是通过窦房结调节的有益作用)。还包括含有公式I化合物(或相关的无水基)作为活性成分的制药组合物,以及制造各种新型化合物的过程。
