of inflammation and inflammatory diseases. Previous caspase-1 inhibitors were in great majority covalent inhibitors and failed in clinical trials. Using a mixed modelling, computational screening, synthesis and in vitro testing approach, we identified a novel class of non-covalent caspase-1 non cytotoxic inhibitors which are able to inhibit IL-1β release in activated macrophages in the low μM range,
靶向炎性体-半胱天冬酶-1 通路的化合物可用于治疗炎症和炎症性疾病。以前的 caspase-1 抑制剂绝大多数是共价抑制剂,在临床试验中失败了。使用混合建模、计算筛选、合成和体外测试方法,我们确定了一类新型非共价 caspase-1 非细胞毒性抑制剂,它们能够在低 μM 范围内抑制活化巨噬细胞中 IL-1β 的释放,符合对于已知的共价抑制剂观察到的最佳活性。我们的化合物可以为进一步优化治疗炎症和炎症性疾病(包括 Covid 19 中失调的炎症)的强效药物奠定基础。
