生物活性
VRT-043198, the drug metabolite of VX-765 (Belnacasan), is a potent, selective and blood-brain barrier permeable inhibitor of interleukin-converting enzyme/caspase-1 subfamily caspases. VRT-043198 exhibits K i values of 0.8 nM and 0.6 nM for ICE/caspase-1 and caspase-4, respectively.
性状
Solid
IC50 & Target[1][2]
Caspase-1 0.8 nM (Ki) Caspase-4 0.6 nM (Ki)
体外研究(In Vitro)
VRT-043198 exhibits 100- to 10,000-fold selectivity against other caspase-3 and -6 to -9.
VRT043198 inhibits the release of interleukin (IL)-1β and IL-18, but it has little effect on the release of several other cytokines, including IL-1α, tumor necrosis factor-, IL-6 and IL-8. VRT-043198 inhibited IL-1β release from both PBMCs (n = 8) and whole blood (n = 4) with IC50 values of 0.67±0.55 and 1.9±0.80 nM, respectively.
VRT-043198 lacks potent antiapoptotic activity.
has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
VX-765 is converted rapidly to VRT-043198 under the action of plasma and liver esterases and also much more slowly in aqueous solution.
VX765 reduces disease severity and the expression of inflammatory mediators in models of rheumatoid arthritis and skin inflammation.
VX765 (25, 50, 100, or 200 mg/kg) inhibits lipopolysaccharide-induced cytokine secretion.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。
