Dapansutrile

Biological Activity

Dapansutrile is a NLRP3 inflammasome inhibitor that disrupts inflammasome formation. Reduces LPS/ATP-induced IL-1β secretion in human and mouse macrophages in vitro, without affecting TNFα levels. Reduces LPS-induced inflammation in vivo. Also reduces joint swelling and markers of inflammation in synovial fluid in a mouse model of acute arthritis. Displays cardioprotective effects in a mouse model of cardiac ischemic reperfusion injury.
