- A practical synthesis of Rho-Kinase inhibitor Y-27632 and fluoro derivatives and their evaluation in human pluripotent stem cells
-
A practical synthesis of the Rho-Kinase inhibitor Y-27632 and two new fluoro derivatives was achieved in seven steps and with a good overall yield of 45% starting from commercially available (R)-1-phenylethylamine. Compared to Y-27632 the new fluoro deriv

- Piperazine compounds and medicinal use thereof
-
The present invention relates to a piperazine compound of the formula wherein R1and R2are each hydrogen, halogen, lower alkyl, lower alkoxy, amino, substituted amino, nitro, hydroxy or cyano, R3, R4and R5are each hydrogen, halogen, lower alkyl, lower alkoxy, nitro, amino, substituted amino or hydroxy, R6and R7are each hydrogen, lower alkyl, lower alkyl substituted by halogen, aralkyl, acyl or lower acyl substituted by halogen, R8and R9are 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.

- Novel DMARDs on the basis of a new concept of dual cytokine regulation, TNF-α suppression and IL-10 augmentation
-
A series of arylpiperazine derivatives was synthesized to obtain agents showing apparent therapeutic effects in a chronic inflammatory animal model, starting from a lead possessing potent dual cytokine regulatory activity in vivo. We found a pyrimidylpipe
