Description: Dilmapimod, also known as SB-681323 and GW-681323 , is p38 MAPK inhibitor. SB-681323 inhibited the p38 MAPK pathway to a greater degree than prednisolone did. SB-681323 inhibited TNF-alpha production. SB-681323 is a potent p38 MAPK inhibitor that potentially suppresses inflammation in COPD. The treatment with SB-681832 is a safe and effective means of reducing hsCRP in patients undergoing elective PCI.
