产品描述

Necrostatin-1(NEC-1,Nec-1a)[(R)-5-([7-chloro-1H-indol-3-yl]methyl)-3-methylimidazoli-dine-2,4-dione]是RIP1的抑制剂,IC50值为0.32 mM [1]。

程序性坏死是凋亡刺激诱导的坏死性细胞死亡的细胞内机制,凋亡刺激是当细胞凋亡的执行被阻止时,死亡域受体与其各自的配体结合而形成的。Necrostatin-1是程序性坏死的小分子抑制剂,也是死亡域受体相关适配器激酶RIP1的选择性变构抑制剂。

体外实验:necrostatin-1是一种选择性的死亡域受体相关适配器激酶RIP1变构抑制剂。RIP1是necrostatin-1抗坏死活性的主要靶标。此外,两个其它的necrostatins,necrostatin-3和necrostatin-5也靶向程序性坏死途径中的RIP1激酶,但通过与necrostatin-1不同的机制起作用。这些研究表明,necrostatins是RIP1激酶的先入类抑制剂,而RIP1激酶是参与程序性坏死激活的关键上游激酶 [2]。

体内实验:在小鼠中研究Nec-1对刀豆素A诱发肝炎的保护作用和机制。结果发现,Nec-1治疗小鼠中,肝功能和组织病理学变化得到改善,且炎性细胞因子的产生被抑制。Western印迹分析表明,在Nec-1治疗小鼠中,TNF-α、IFN-γ、IL2、IL6和RIP1的表达显著减少,并进一步通过免疫荧光和免疫组化进行证实。此外,Nec-1也显著减少自噬体的形成。这些研究表明,Nec-1通过RIP1相关的和自噬相关的途径阻止刀豆素A诱导的肝损伤 [3]。

临床试验:目前为止,necrostatin-1仍处于临床前开发阶段。
