CA 2306811

Piperazine compounds represented by the following general formula (I) or pharmaceutically acceptable salts thereof and drugs comprising these compounds, wherein R1 and R2 represent each hydrogen, halogeno, lower alkyl, lower alkoxy, optionally substituted amino, nitro, hydroxy or cyano; R3, R4 and R5 represent each hydrogen, halogeno, lower alkyl, lower alkoxy, nitro, optionally substituted amino or hydroxy; R6 and R7 represent each hydrogen, optionally halogenated lower alkyl, aralkyl, acyl or halogenated lower acyl; R8 and R9 represent each hydrogen or lower alkyl; Y represents lower alkylene, etc.; and the ring A represents phenyl, pyrimidyl, thiazolyl, pyridyl, pyrazyl or imidazolyl. Because of having excellent TNF-.alpha. production inhibitory effect and/or IL-10 production promoting effect, these compounds are useful as TNF-.alpha. production inhibitors and/or IL-10 production promoters with high safety. They are useful as preventives or remedies for, e.g., chronic inflammatory diseases, acute inflammatory diseases, inflammatory diseases caused by infection, autoimmune diseases, allergic diseases and other TNF- .alpha.-mediated diseases.
