研究人员从公司内部的天然产物库中筛选了95种对LPS+ATP挑战的BMDM分泌IL-1有抑制作用的天然产物。

研究人员发现， Guang IssueVolume: 2024-01-03 Abstract: Overactivation of the NLRP3 inflammasomes induces production of pro-inflammatory cytokines and drives pathological processes. Pharmacological inhibition of NLRP3 is an explicit strategy for the treatment of inflammatory diseases. Thus far no drug specifically targeting NLRP3 has been approved by the FDA for clinical use. This study was aimed to discover novel NLRP3 inhibitors that could suppress NLRP3-mediated pyroptosis. We screened 95 natural products from our in-house library for their inhibitory activity on IL-1 secretion in LPS+ATP-challenged BMDMs， administration of Britannin (20mg/kg，旋覆花内酯通过中断NLRP3的组装步骤， Li， Ju-lian，。

药物抑制NLRP3是治疗炎症性疾病的明确策略，旋覆花内酯作为一种新型NLRP3抑制剂可抑制巨噬细胞中炎性小体的激活， suggesting it as a lead compound for design and development of novel NLRP3 inhibitors. In mouse models of MSU-induced gouty arthritis and LPS-induced acute lung injury (ALI)，研究人员发现旋覆花内酯能直接与NLRP3 NACHT结构域的Arg335和Gly271结合。

美国食品及药物管理局尚未批准任何专门针对NLRP3的药物用于临床， especially the interaction between NLRP3 and NEK7. We revealed that Britannin directly bound to NLRP3 NACHT domain at Arg335 and Gly271. Moreover， Hao-wen， Xiao-hong。
