Pyrrolealdehydes of the formula I ##STR1## wherein R and R.sup.1 independently of one another denote hydrogen or alkyl with 1 to 4 C atoms, R.sup.2 denotes alkyl, which is substituted by acylamino of the formula II ##STR2## wherein X stands for an oxygen or sulphur atom and R.sup.3 denotes hydrogen, optionally substituted alkyl or alkylamino, cycloalkyl with 5 to 7 C atoms, optionally substituted phenyl, an amino group or an optionally substituted phenylamio group, and pharmaceutically acceptable acid addition salts thereof, and wherein R.sup.3 cannot represent hydrogen if R and R.sup.1 denote hydrogen and the pyrrole ring is formylated in the 3-position, their preparation and their use.
公式I表示式为:##STR1## 其中R和R.sup.1分别独立地表示氢或1至4个碳原子的烷基,R.sup.2表示烷基,其被式II的酰胺基取代,式II表示为:##STR2## 其中X代表氧或
硫原子,R.sup.3表示氢,可选取代的烷基或烷基胺基,带有5至7个碳原子的环烷基,可选取代的苯基,
氨基或可选取代的苯基
氨基,以及其药学上可接受的酸盐加成物。当R和R.sup.1表示氢且
吡咯环在3位被甲酰化时,R.sup.3不能表示氢。本文还涉及其制备和使用。
