The invention relates to novel 1-phenyl-2-amino-1,3-propanediol-N-alkyl derivatives having the general formula I ##STR1## wherein R.sub.1 is hydrogen, alkyl having from 1 to 8 carbon atoms or phenoxymethyl, and R.sub.2 is hydrogen, alkyl having from 1 to 8 carbon atoms or 2,2-diphenylethyl, with the proviso that if R.sub.1 is phenoxymethyl then R.sub.2 may stand only for methyl, and if R.sub.2 is 2,2-diphenylethyl then R.sub.1 may stand only for hydrogen, and its isomers and pharmaceutically acceptable salts. Furthermore, the invention relates to a process for preparing these compounds. The novel 1-phenyl-2-amino-1,3-propanediol-N-alkyl derivatives having the general formula I possess significant anti-anginose activity and show several other biological activities.
本发明涉及具有通式I的新型1-苯基-2-氨基-1,3-丙二醇-N-烷基衍生物,其中R1为氢、1至8个碳原子的烷基或苯氧甲基,R2为氢、1至8个碳原子的烷基或2,2-二苯乙基,但如果R1为苯氧甲基,则R2仅能代表甲基,如果R2为2,2-二苯乙基,则R1仅能代表氢,并且其异构体和药学上可接受的盐。此外,本发明涉及一种制备这些化合物的方法。具有通式I的新型1-苯基-2-氨基-1,3-丙二醇-N-烷基衍生物具有显著的抗心绞痛活性,并显示出几种其他生物活性。
