- 產(chǎn)品描述: Necrosulfonamide是一種特異的、有效的細(xì)胞壞死抑制劑,通過抑制MLKL發(fā)揮其作用
- 靶點(diǎn): necrosis(MLKL);MLK
- 體外研究:
Necrosulfonamide通過阻止MLKL的N端CC區(qū)域的功能、抑制MLKL介導(dǎo)的壞死。它能抑制RIP3激活的下游壞死。Necrosulfonamide在不表達(dá)RIP3的Panc-1細(xì)胞中對(duì)TNF-α和Smac mimetic誘導(dǎo)的凋亡不起任何作用,即使?jié)舛冗_(dá)到5 μM。Necrosulfonamide在人類細(xì)胞中有效抑制壞死,但在小鼠細(xì)胞中無此作用。necrosulfonamide具有種屬特異性可能是因?yàn)閚ecrosulfonamide的結(jié)合依賴于人源MLKL的第86位半胱氨酸,而在小鼠MLKL中,這一位點(diǎn)被色氨酸所替代
- 體內(nèi)研究:
Necrosulfonamide (NSA) is a small molecule that specifically inhibits necroptosis by targeting MLKL, the terminal executioner of necroptosis.
- 細(xì)胞實(shí)驗(yàn): Cell lines: HT-29細(xì)胞 Concentrations: 1 μM Incubation Time: 8 或 12 hrs Method: 細(xì)胞壞死抑制劑對(duì)MLKL磷酸化產(chǎn)生負(fù)面效果。用T/S/Z處理細(xì)胞,加入或者不加入細(xì)胞壞死抑制劑,孵育12小時(shí)或8小時(shí)。通過測定培養(yǎng)基中釋放的蛋白酶活性檢測死細(xì)胞的數(shù)量。獲取細(xì)胞提取物用于western blot分析。終濃度為10 μM的necrostatin-1或1 μM necrosulfonamide被用來阻止細(xì)胞壞死
- 動(dòng)物實(shí)驗(yàn): Animal Models: Male Wistar rats Dosages: 1.65 mg/kg Administration: i.p.
