  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。

  and used this library to systematically interrogate esterase preference for chain length, branching patterns, and polarity to differentiate common classes of esterase substrates. Two structurally homologous bacterial esterases were screened against this library, refining their previously broad overlapping substrate specificity. Vibrio cholerae esterase ybfF displayed a preference for γ-position thioethers

  细胞酯酶通过在各种底物上进行水解反应来催化许多重要的生物学功能。酯酶的滥交使底物偏好和生物学功能的分配变得复杂。为了识别控制酯酶底物识别的通用因素，我们设计了一个32位成员的荧光酯底物的结构-活性关系（SAR）库，并使用该库系统地查询酯酶对链长，分支模式和极性的偏好，以区分常见的酯酶底物。针对该文库筛选了两种结构同源的细菌酯酶，完善了它们先前广泛的重叠底物特异性。霍乱弧菌酯酶ybfF显示出对γ-位硫醚和醚的偏爱，而来自结核分枝杆菌的Rv0045c则偏爱带有或不带有硫醚的支链底物。我们确定这种底物分化部分受ybfF中单个底物选择性残基Tyr-119和Rv0045c中His-187的控制。这些残基的相互取代改变了每种酯酶的底物偏好。这项工作表明酯酶的选择性可基于过渡态稳定度进行调整，将硫醚确定为酯酶底物的未充分利用的官能团，并提供了区分结构同工酶的快速方法。该SAR库可能具有多方面的未来应用，
