生物活性

NLRP3-IN-87 is a selective and orally active NLRP3 inhibitor with a Kd of 0.23 μM. NLRP3-IN-87 binds directly to the NLRP3 NACHT domain, disrupts NLRP3-NEK7 and NLRP3-ASC interactions, inhibits ASC oligomerization, and blocks inflammasome assembly. NLRP3-IN-87 suppresses caspase-1 activation and IL-1β secretion. NLRP3-IN-87 exhibits anti-inflammatory and analgesic activity, reducing joint swelling, inflammation, and pain in an MSU (HY-B2130A)-induced acute gout mouse model. NLRP3-IN-87 can be used for the research of gout[1].

NLRP3-IN-87 (Compound M48) 可直接与纯化的人源 NLRP3 蛋白的 NACHT 结构域结合,其 Kd 值为 0.23 μM[1]
NLRP3-IN-87 (1-20 nM; 30 min 预处理) 在 BMDM 细胞中可强效抑制 NLRP3 炎症小体介导的 IL-1β 分泌,其 IC50 为 11.9 nM,同时可阻断 caspase-1 的活化[1]
NLRP3-IN-87 (50-500 nM) 呈剂量依赖性地破坏经 LPS (HY-D1056)/Nigericin (HY-127019) 激活的小鼠 BMDM 中 NLRP3NEK7 及 ASC 的相互作用[1]
NLRP3-IN-87 (10-100 nM; 30 min 预处理) 可呈剂量依赖性抑制经 LPS/Nigericin 激活的小鼠骨髓来源巨噬细胞 (BMDMs) 中 ASC 的寡聚化和斑点形成[1]
NLRP3-IN-87 (0.01-1000 μM; 10-90 min) 可在 LPS 刺激的小鼠 BMDM 裂解物中以浓度依赖时间依赖方式提升 NLRP3 蛋白的热稳定性[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
