receptor-interacting protein kinases, RIPK1 and RIPK3, and the mixed lineage kinase domain-like (MLKL). Necroptosis contributes to the pathophysiology of various inflammatory, infectious, and degenerative diseases. Thus, identification of low MW inhibitors for necroptosis has broad therapeutic relevance. Here, we identified that the pan-Raf inhibitor TAK-632 was also an inhibitor of necroptosis. We have further
背景和目的坏死病是一种程序化的,不依赖半胱天冬酶的细胞死亡,是由受体相互作用蛋白激酶RIPK1和RIPK3以及混合谱系激酶结构域样蛋白(MLKL)介导的。坏死病有助于各种炎性,感染性和退行性疾病的病理生理。因此,鉴定用于坏死性坏死的低分子量抑制剂具有广泛的治疗意义。在这里,我们确定了泛Raf抑制剂TAK-632也是坏死病的抑制剂。通过靶向RIPK1和RIPK3,我们进一步产生了更具选择性,更强效的TAK-632类似物。实验方法通过MTT,丙啶染色或CellTiter-Glo发光测定法测量细胞活力。通过免疫印迹,免疫沉淀,和体外激酶测定。通过药物亲和力响应靶标稳定性测定法和生物素化TAK-632的下拉测定法鉴定TAK-632的下游靶标。还使用了TNF-α诱导的全身性炎症反应综合征(SIRS)的小鼠模型来研究TAK-632在体内预防坏死病相关炎症的作用。关键结果TAK-632可防止人和小鼠细胞
