Alkylenediamine amides corresponding to the general formula (I) ##STR1## in which R.sub.1 and R.sub.2 each represent, independently of one another, a hydrogen atom, an alkyl having 1 to 4 carbon atoms or the benzyl radical, n is equal to 2, 3 or 4 and R represents either a cycloalkyl radical having 3 to 6 carbon atoms, or a radical ##STR2## in which m is 0, 1 or 2, ##STR3## in which m is 0, 1 or 2 and p is 0, 1 or 2, and also their addition salts with pharmaceutically acceptable acids. These compounds may be prepared by reacting an aminoamide ##STR4## with a 4-amino-2-halogeno-6,7-dimethoxyquinazoline (II). The compounds are useful in treating cardiovascular disorders, and pharmaceutical compositions containing the compounds are also claimed.
对应于一般式(I)的亚烷基二胺酰胺,其中R.sub.1和R.sub.2各自独立地表示氢原子、具有1至4个碳原子的烷基或苄基基团,n等于2、3或4,而R表示具有3至6个碳原子的环烷基基团,或者是一个基团##STR2##在其中m为0、1或2,##STR3##在其中m为0、1或2,p为0、1或2,并且它们与药学上可接受的酸的加合物。这些化合物可以通过将氨基酰胺##STR4##与4-氨基-2-卤代-6,7-二甲氧基喹嗪(II)反应制备。这些化合物在治疗心血管疾病方面有用,并且还声称含有这些化合物的制药组合物。
