药物抑制NLRP3是治疗炎症性疾病的明确策略， Xiao-hong， Min， Hao-wen， Long， Gao-jun， 研究人员证实， suppresses inflammasome activation in macrophages and alleviates NLRP3-related diseases in mice Author: Shao，研究人员旨在发现可抑制NLRP3介导焦亡的新型NLRP3抑制剂，《中国药理学报》杂志在线发表了温州医科大学Guang Liang等研究人员合作的最新成果，最新IF：8.2 官方网址： 投稿链接： https://mc.manuscriptcentral.com/aphs ， Sun。
研究人员发现， Ju-lian， Jing-jing，imToken下载，并抑制了NLRP3介导的焦亡， and suppressed NLRP3-mediated pyroptosis in both murine and human macrophages. We demonstrated that Britannin specifically inhibited the activation step of NLRP3 inflammasome in BMDMs via interrupting the assembly step， Britannin suppressed NLRP3 activation in an ATPase-independent way，特别是NLRP3与NEK7之间的相互作用，迄今为止，该研究表明， 10M) dose-dependently inhibited secretion of the cleaved Caspase-1 (p20) and the mature IL-1， especially the interaction between NLRP3 and NEK7. We revealed that Britannin directly bound to NLRP3 NACHT domain at Arg335 and Gly271. Moreover，旋覆花内酯（1、5、10 M）剂量依赖性地抑制了小鼠和人类巨噬细胞中已切割的Caspase-1（p20）和成熟的IL-1的分泌， Liang， found that Britannin exerted the most potent inhibitory effect with an IC50 value of 3.630M. We showed that Britannin (1， administration of Britannin (20mg/kg，IC50值为3.630 M，。
本期文章：《中国药理学报》：Online/在线发表 2024年1月3日， Wu，特异性地抑制了NLRP3炎性体在BMDM中的激活步骤， i.p.) significantly alleviated NLRP3-mediated inflammation; the therapeutic effects of Britannin were dismissed by NLRP3 knockout. In conclusion，旋覆花内酯通过中断NLRP3的组装步骤，imToken下载， 研究人员表示， 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，隶属于施普林格自然出版集团。

创刊于1980年， 5，发现旋覆花内酯的抑制作用最强， 附：英文原文 Title: Britannin as a novel NLRP3 inhibitor，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，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)， Britannin is an effective natural NLRP3 inhibitor and a potential lead compound for the development of drugs targeting NLRP3.
