产品描述: | Necrosulfonamide是一种特异的、有效的细胞坏死抑制剂,通过抑制MLKL发挥其作用 |
靶点: |
necrosis(MLKL);MLK |
体外研究: |
Necrosulfonamide通过阻止MLKL的N端CC区域的功能、抑制MLKL介导的坏死。它能抑制RIP3激活的下游坏死。Necrosulfonamide在不表达RIP3的Panc-1细胞中对TNF-α和Smac mimetic诱导的凋亡不起任何作用,即使浓度达到5 μM。Necrosulfonamide在人类细胞中有效抑制坏死,但在小鼠细胞中无此作用。necrosulfonamide具有种属特异性可能是因为necrosulfonamide的结合依赖于人源MLKL的第86位半胱氨酸,而在小鼠MLKL中,这一位点被色氨酸所替代 |
体内研究: |
Necrosulfonamide (NSA) is a small molecule that specifically inhibits necroptosis by targeting MLKL, the terminal executioner of necroptosis. |
细胞实验: |
Cell lines: HT-29细胞 Concentrations: 1 μM Incubation Time: 8 或 12 hrs Method: 细胞坏死抑制剂对MLKL磷酸化产生负面效果。用T/S/Z处理细胞,加入或者不加入细胞坏死抑制剂,孵育12小时或8小时。通过测定培养基中释放的蛋白酶活性检测死细胞的数量。获取细胞提取物用于western blot分析。终浓度为10 μM的necrostatin-1或1 μM necrosulfonamide被用来阻止细胞坏死 |
动物实验: |
Animal Models: Male Wistar rats Dosages: 1.65 mg/kg Administration: i.p. |
