The invention concerns new analgesic 6-acylaminotetrahydro-1,3,5-triazine-2,4-dione derivatives of the formula: ##STR1## in which R.sup.1 is an optionally substituted phenyl, phenyl- (1-4C)alkyl, naphthyl, monocyclic or bicyclic heteroaromatic or (monocyclic or bicyclic heteroaromatic)- (1-4C)alkyl radical, R.sup.2 is a (3-8C)cycloalkyl, [(3-8C)cycloalkyl]-(1-4C)alkyl or (3-6C)alkenyl radical, or an optionally substituted phenyl or phenyl- (1-4C)alkyl radical, and R.sup.3 is a (1-4C)alkyl radical, preferably a methyl radical; together with pharmaceutically acceptable salts thereof. Also provided are processes for the manufacture of, and pharmaceutical compositions of, derivatives of formula I and salts thereof. Some of the derivatives of formula I possess anti-inflammatory properties and/or are inhibitors of the enzyme prostaglandin synthetase in addition to possessing analgesic properties. A typical compound of the invention is 3-(thien-2-yl)-6-[(N-acetyl)isobutylamino]tetrahydro-1,3,5-triazine-2,4-di one.
本发明涉及新型镇痛剂6-酰胺基四氢-1,3,5-三嗪-2,4-二酮衍生物,其化学式为:##STR1## 其中R.sup.1是一个可选取的取代苯基,苯基-(1-4C)烷基,萘基,单环或双环杂环芳基或(单环或双环杂环芳基)-(1-4C)烷基基团,R.sup.2是一个(3-8C)环烷基,[(3-8C)环烷基]-(1-4C)烷基或(3-6C)烯基基团,或一个可选取的取代苯基或苯基-(1-4C)烷基基团,R.sup.3是一个(1-4C)烷基基团,优选是一个甲基基团;以及其药学上可接受的盐。还提供了制备公式I衍生物及其盐的过程和制药组合物。公式I的某些衍生物除了具有镇痛作用外,还具有抗炎性和/或是酶前列腺素合成酶的抑制剂性质。本发明的典型化合物是3-(噻吩-2-基)-6-[(N-乙酰基)异丁基氨基]四氢-1,3,5-三嗪-2,4-二酮。
