The invention relates to indoleacetic acid derivatives represented by general formula (I), [wherein X represents a piperidino group, a 1-pyrrolidinyl group or a 3-hydroxy-1-pyrrolidinyl group, Y represents a, (wherein R' represents a hydrogen atom or a lower alkyl group, and ℓ represents 0, 1 or 2) or β, (wherein R2 represents a hydrogen atom, a lower akyl group or a hydroxy group, m represents 0, 1 or 2, and n represents 1, 2 or 3)] and their salts, and antiinflammatory agents, antirheumatic agents and antiulcer agents containing them as active ingredients. The compounds possess a strong antiinflammatory action while causing extremely reduced troubles of digestive organs which is a serious defect with conventional non-steroidal antiinflammatory agents, and possess an excellent antiulcer action as well.
本发明涉及通式(I)代表的吲哚乙酸衍生物,[其中 X 代表哌啶基、1-吡咯烷基或 3-羟基-1-吡咯烷基,Y 代表 a,(其中 R' 代表氢原子或低级烷基,ℓ 代表 0、其中 R2 代表氢原子、低级烷基或羟基,m 代表 0、1 或 2,n 代表 1、2 或 3)]及其盐类,以及含有它们作为活性成分的抗炎剂、抗风湿剂和抗溃疡剂。这些化合物具有很强的消炎作用,同时能极大地减少消化器官的不适(这是传统非甾体类消炎药的一个严重缺陷),而且还具有很好的抗溃疡作用。
