role in driving inflammation and disease pathology, cell necrosis has gradually been verified as a promising therapeutic target for treating atherosclerosis, systemic inflammatory response syndrome (SIRS), and ischemia injury, among other diseases. Most necrosis inhibitors targeting receptor-interacting protein 1 (RIP1) still require further optimization because of weak potency or poor metabolic stability
基于其在驱动炎症和疾病病理学中的重要作用,细胞坏死已逐渐被证实是治疗动脉粥样硬化,全身性炎症反应综合征(SIRS)和缺血性损伤等疾病的有前途的治疗靶标。由于效价弱或代谢稳定性差,大多数靶向受体相互作用蛋白1(RIP1)的坏死抑制剂仍需要进一步优化。我们进行了表型筛选,并确定了具有新型酰胺结构的微摩尔分子。药物化学努力产生了高度有效的,选择性的和代谢稳定的候选药物,化合物56(RIPA -56)。生化研究和分子对接表明,RIP1是这一新的III型激酶抑制剂新系列的直接靶标。在SIRS小鼠疾病模型中,有56种有效降低了肿瘤坏死因子α(TNFα)诱导的死亡率和多器官损伤。与已知的RIP1抑制剂相比,56在人和鼠细胞中均有效,在体内更稳定,并且在动物模型研究中有效。
