Background |
Necrostatin-1 is a potent, selective and cell-permeable inhibitor of necroptosis. It acts by inhibiting the death domain receptor kinase RIP (RIP1) in the necroptosis pathway. |
Biological Activity |
Necrostatin-1是一种有效,选择性和可渗透细胞的坏死性凋亡 (necroptosis) 抑制剂,在Jurkat细胞中的 EC50 为490 nM。它通过抑制坏死性凋亡途径中的死亡域受体激酶RIP (RIP1) 起作用。 |
In Vitro |
Necrostatin-1(Nec-1)(30μM)通过抑制坏死细胞死亡来增加心肌细胞祖细胞(CMPCs)的存活[4]。通过Necrostatin-1(Nec-1)预处理在1.5小时分别为92.3%和82.9%,在3.0小时分别为84.4%和78.6%,改善由3.0μM和6.0μM紫草素引起的C6胶质瘤细胞活力的降低。同样,Ucr胶质瘤细胞的生存能力由Necrostatin-1在1.5小时时升高至91.6%和81.5%,在3.0小时时分别升高81.8%和71.2%[3]。Necrostatin-1(Nec-1)可阻止放射性对比培养基(RCM)诱导的管周毛细血管扩张,这表明RIP1激酶结构域在调节微血管血流动力学和造影剂诱导的AKI(CIAKI)的病理生理学方面与细胞死亡无关的新作用[2]。Necrostatin-1(Nec-1)是在多种细胞类型中存在胱天蛋白酶抑制的情况下由死亡域受体(DR)刺激引起的细胞死亡的特异性和有效的小分子抑制剂。 Necrostatin-1有效抑制TNFα诱导的L929细胞坏死死亡,不需要外源性caspase抑制剂[1]。 |
In Vivo |
Necrostatin-1(Nec-1)诱导肾小管移位并影响RCM应用后肾小管周围毛细血管扩张的动力学。在RCM前15分钟单次腹膜内施用单剂量的Necrostatin-1(1.65 mg/kg体重,腹腔注射),在观察期内防止恢复至基线水平[2]。 |
Cell Experiment |
将C6(3×10 5细胞/孔)和U87(1.5×10 5细胞/孔)胶质瘤细胞接种到96孔微量培养板上并培养24小时。将PBS加入对照组,并将紫草素加入实验组中以达到最终浓度。在指定时间点处紫草素处理后使用MTT测定评估细胞活力。使用自动多孔分光光度计读取570nm处的吸光度值(A)。来自相同细胞系的两组神经胶质瘤细胞分别用较低或较高浓度的紫草素处理;在与指定浓度的紫草素共孵育之前,用100μMNecrostatin-1或40μMz-VAD-fmk处理另外两组神经胶质瘤细胞1小时。此外,另外两组胶质瘤细胞仅在相应的时间点用100μMNecrostatin-1或40μMZ-VAD-fmk治疗[3]。 |
Animal Experiment |
使用小鼠[2] 8-10周龄雄性C57BL/6小鼠(平均体重约23g)。小鼠通过尾静脉静脉内施用200μLPBS或放射性对比培养基(RCM)。腹膜内施用单剂量的Z-VAD-fmk(10mg/kg体重)或Necrostatin-1(1.65mg/kg体重)15分钟。在RCM注射之前。在RCM施用后24小时(再灌注后48小时)收获小鼠。从眶后出血获得血液样品,并测定尿素和肌酸酐的血清水平。 |
