The present invention relates to novel 3-benzylidene-1-carbamoyl-2-pyrroridone analogues having advantage anti-inflammatory activities, which is represented by the formula: ##STR1## wherein R.sup.1 and R.sup.2 each is independently hydrogen, alkyl, alkoxy, or halogen; R.sup.3 is hydrogen or acyl; R.sup.4 is hydrogen, alkyl, hydroxy, alkoxy, cyano, or halogen; R.sup.5 and R.sup.6 each is independently hydrogen, alkyl, aryl, aralkyl, heterocyclic group, substituted or unsubstituted amino, or OR.sup.7 wherein R.sup.7 is hydrogen, alkyl, aryl, acyl, or aralkyl, or taken together with the adjacent nitrogen atom may form heterocyclic group which may contain N, O, and/or S, and X and Y each is independently O, S, substituted or unsubstituted imino, or substituted or unsubstituted methylene. In more detail, the present invention provides an anti-inflammatory agent which is useful for the treatment of chronic inflammation and has little side effect, e.g., stomach disease.
本发明涉及具有优越抗炎活性的新型3-苯甲基亚甲基-1-氨基甲酰基-2-吡咯酮类似物,其表示为以下式子:##STR1## 其中R.sup.1和R.sup.2各自独立地为氢、烷基、烷氧基或卤素;R.sup.3为氢或酰基;R.sup.4为氢、烷基、羟基、烷氧基、氰基或卤素;R.sup.5和R.sup.6各自独立地为氢、烷基、芳基、芳基烷基、杂环基、取代或未取代的氨基或OR.sup.7,其中R.sup.7为氢、烷基、芳基、酰基或芳基烷基,或与相邻的氮原子一起可以形成可能包含N、O和/或S的杂环基,X和Y各自独立地为O、S、取代或未取代的亚胺基或取代或未取代的亚甲基。更详细地说,本发明提供了一种抗炎药物,可用于治疗慢性炎症,并具有较小的副作用,例如胃病。
