throughput enzymatic and parasitic assays along with in vitro pharmacokinetics. Co-crystallization of the most potent compound in our series (CL-2) with PfKRS revealed its structural basis of enzymatic binding and potency. Further, we report that CL-2 has performed better than cladosporin in terms of metabolic stability. It thus represents a new lead for further optimization toward the development of antimalarial
在这里,我们描述了一组受枝孢菌素启发的化合物的系统构效关系 (SAR),枝孢菌素是一种靶向寄生虫(恶性疟原虫)赖氨酰 tRNA 合成酶 (KRS)的工具化合物。使用高通量酶促和寄生虫测定以及体外药代动力学评估了基于枝孢菌素化学支架的点变化和其他逻辑修饰和杂交合成的四组类似物。我们系列中最有效的化合物 ( CL-2 ) 与Pf KRS 的共结晶揭示了其酶促结合和效力的结构基础。此外,我们报告说CL-2在代谢稳定性方面表现优于枝孢菌素。因此,它代表了进一步优化抗疟药物开发的新线索。总的来说,该系列与先导化合物一起提供了关于即使是最轻微的化学修饰如何在增强或降低化学支架效力方面发挥重要作用的见解。
