A series of α,β-unsaturated ketone derivatives were synthesized, and their anti-inflammatory activity toward NLRP3 inflammasome was evaluated in vitro. Several compounds were identified as anti-inflammatory agents, among which compound A21 exhibited potent anti-inflammatory activity in a dose-dependent manner with an IC50 of 0.95 μM. Moreover, a preliminary structure-activity relationship was also summarized.

Key words: a,β-Unsaturated ketone, NLRP3, IL-1β, Anti-inflammatory
