Description: S-2474 is a COX-2 inhibitor potentially for the treatment of rheumatoid arthritis (RA). S-2474 rescues cortical neurons from human group IIA secretory phospholipase A(2)-induced apoptosis. S-2474 significantly prevented neurons from Abeta(25 - 35)- and Abeta(1 - 40)-induced cell death. S-2474 ameliorated Abeta-induced apoptotic features such as the condensation of chromatin and the fragmentation of DNA completely. S-2474 exhibits protective effects against neurotoxicity of Abeta. S-2474 may possess therapeutic potential for AD via ameliorating degeneration in neurons as well as suppressing chronic inflammation in non-neuronal cells.
