摘要:

NLRP3炎症小体为靶点,设计并合成了一系列α,β-不饱和酮类化合物,并测定了其体外抗炎活性。发现数个化合物有强的抑制IL-1β释放的抗炎活性,其中A21表现出最强的抗炎活性,并呈剂量依赖关系,IC500.95μM。论文中还总结了该类化合物初步的构效关系。

关键词: α,β-不饱和酮, 炎症小体, IL-1β, 抗炎活性

Abstract:

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
