Dapansutrile (original) (raw)

Dapansutrile (OLT1177) is an inhibitor of the NLRP3 (nucleotide-binding domain leucine-rich repeat and pyrin domain containing receptor 3) inflammasome. An inflammasome can be defined as an immune system receptor that induces inflammation through the activation of caspase 1 and caspase 11 when it is triggered by damaged cells, microbial pathogens, and stress. NLRP3 is a canonical inflammasome. The NLRP3 inflammasome comprises NLRP3, the apoptosis spec-like protein (ASC) and the caspase-1 (Figure 1). The NLRP3 inflammasome forms by binding to pattern recognition receptors (PRRs) and damage associated molecular patterns (DAMPS) that activate caspase 1 which then signals for the secretion of pro-inflammatory cytokines IL-1β and IL-18 resulting in pyroptosis Constant activation of the NLRP3 in
