摘要:
The present invention provides a therapeutic drug for non-viral hepatitis, which contains a piperazine compound represented by the following formula (I) or pharmaceutically acceptable salt thereof as an active ingredient.
摘要:
The present invention relates to a piperazine compound of the formula wherein R1 and R2 are each hydrogen, halogen, lower alkyl, lower alkoxy, amino, substituted amino, nitro, hydroxy or cyano, R3, R4 and R5 are each hydrogen, halogen, lower alkyl, lower alkoxy, nitro, amino, substituted amino or hydroxy, R6 and R7 are each hydrogen, lower alkyl, lower alkyl substituted by halogen, aralkyl, acyl or lower acyl substituted by halogen, R8 and R9 are each hydrogen or lower alkyl, Y is lower alkylene and the like, and ring A is phenyl, pyrimidyl, thiazolyl, pyridyl, pyrazyl or imidazolyl, a pharmaceutically acceptable salt thereof and pharmaceutical agents containing these compounds. The compound of the present invention has superior TNF-α production inhibitory effect and/or IL-10 production promoting effect, and, since it is free of or shows only strikingly reduced expression of an effect on the central nervous system, the compound is useful as a highly safe and superior TNF-α production inhibitor an/or IL-10 production promoter and is useful as an agent for the prophylaxis or treatment of various diseases caused by abnormal TNF-α production, diseases curable with IL-10, such as chronic inflammatory diseases, acute inflammatory diseases, inflammatory diseases due to infection, autoimmune diseases, allergic diseases, and TNF-α mediated diseases.
