Dilmapimod（Cat No.:I005975）, also known as SB-681323 and GW-681323, is a potent inhibitor of p38 MAPK (mitogen-activated protein kinase). It has demonstrated superior inhibition of the p38 MAPK pathway compared to prednisolone and has shown efficacy in suppressing inflammation, particularly in chronic obstructive pulmonary disease (COPD). Additionally, Dilmapimod has been found to inhibit the production of TNF-alpha, a pro-inflammatory cytokine. It has also been investigated for its potential to reduce high-sensitivity C-reactive protein (hsCRP) levels in patients undergoing elective percutaneous coronary intervention (PCI).
