computational docking, synthesis, and enzymatic screening was applied with the aim of lead structure development. Hereby, covalent inhibitors were developed, which show enhanced inhibition with a 22-fold increase in IC50 values compared to previous work. Comprehensive insights into the binding prerequisites to ChlaDUB1 are provided, establishing the foundation for an additional specific antichlamydial therapy
被细胞内病原体感染后,宿主细胞激活细胞凋亡途径以限制病原体复制。因此,专性细胞内病原体沙眼衣原体(沙眼和性传播疾病的主要原因)的有效增殖取决于对宿主细胞凋亡的抑制。沙眼衣原体将去泛素酶 ChlaDUB1 分泌到宿主细胞中,导致抗凋亡蛋白的稳定化等相互作用,从而抑制宿主细胞凋亡。因此,针对细菌效应蛋白可能会带来新的治疗可能性。为了探索 ChlaDUB1 的活性位点,应用了计算对接、合成和酶筛选的迭代循环,以开发先导结构。由此,开发了共价抑制剂,其显示出增强的抑制作用,与之前的工作相比,IC 50值增加了22倍。提供了对 ChlaDUB1 结合先决条件的全面见解,为小分子的额外特异性抗衣原体疗法奠定了基础。
