Pharmacologically-active aminopyrrole derivatives of the formula ##STR1## wherein: R is selected from hydrogen, (C.sub.1-4)alkyl, benzyl and chlorobenzyl; R.sub.1 is selected from hydrogen, (C.sub.1-4)alkyl, phenyl and phenyl substituted by a radical selected from methyl, ethyl, methoxy, ethoxy, benzyloxy, fluoro, chloro and bromo; R.sub.2 and R.sub.3 taken together, represent a benzylidene or a chlorobenzylidene radical; R.sub.4 is selected from (C.sub.2-4)alkanoyl; benzoyl, and benzoyl substituted by a radical selected from chloro, methoxy or ethoxy; R.sub.5 is selected from hydrogen, (C.sub.1-4)alkyl, or trifluoromethyl and a salt thereof with a pharmaceutically-acceptable acid. The compounds have anti-inflammatory and CNS-depressant utility. They are also useful as analgesics and antipyretics and display a very low degree of anti-ulcerogenic activity.
公式为 ##STR1## 的药理活性氨基吡咯衍生物,其中:R选择氢,(C.sub.1-4)烷基,苯甲基和氯苯甲基;R.sub.1选择氢,(C.sub.1-4)烷基,苯基和苯基被甲基,乙基,甲氧基,乙氧基,苄氧基,氟,氯和溴中的一种基团取代;R.sub.2和R.sub.3一起表示苯甲亚甲基或氯苯甲亚甲基基团;R.sub.4选择(C.sub.2-4)烷酰基;苯甲酰基,以及被氯,甲氧基或乙氧基中的一种基团取代的苯甲酰基;R.sub.5选择氢,(C.sub.1-4)烷基或三氟甲基,并且与药学上可接受的酸盐一起使用。这些化合物具有抗炎和中枢神经系统抑制剂的效用。它们也用作镇痛剂和退烧药,并显示出非常低的抗溃疡活性。
