Potent and selective inhibitors of bacterial methionyl tRNA synthetase derived from an oxazolone–dipeptide scaffold
摘要:
The preparation and structure-activity relationships (SARs) of potent and selective small molecule inhibitors of bacterial methionyl-tRNA synthetase (MetRS) derived from an oxazolone-dipeptide scaffold are described. Examples combine Staphylococcus aureus MetRS (SaMetRS) potency with selectivity over human MetRS. As a result of the SAR expansion compound 14a was identified, as a potent SaMetRS inhibitor (IC50 = 18 nM) having moderate inhibition of MetRS derived from Enterococci faecalis (IC50 = 3.51 muM).

As a continuation of our previous work, a series of new phenyl acrylamide derivatives (4Aa-g, 4Ba-t, 5 and 6a-c) were designed and synthesized as non-nucleoside anti-HBV agents. Among them, compound 4Bs could potently inhibit HBV DNA replication in wild-type and lamivudine (3TC)/entecavir resistant HBV mutant strains with IC50 values of 0.19 and 0.18 μM, respectively. Notably, the selective index value

for hit validation. Optimization of 4d guided by structural biology identified potent inhibitors of Notum activity that restored Wnt/β-catenin signaling in cell-based models. The [1,2,4]triazolo[4,3-b]pyradizin-3(2H)-one series 4 represent a new chemical class of Notum inhibitors and the first to be discovered by a VS campaign. These results demonstrate the value of VS with well-designed docking models
Notum 是 Wnt 信号传导的负调节因子,通过棕榈油酸酯的水解发挥作用,棕榈油酸酯是 Wnt 活性所必需的。 Notum 抑制剂可用于以 Notum 活性功能失调为根本原因的疾病。使用大型商业库的基于对接的虚拟屏幕 (VS) 筛选出 952 种化合物,用于作为 Notum 抑制剂的实验验证。 VS 成功使用了 31 种 IC 50 < 500 nM 的化合物。然后应用关键的选择过程,选择两个集群和两个单例(1-4d )进行命中验证。以结构生物学为指导的4d优化确定了 Notum 活性的有效抑制剂,可在细胞模型中恢复 Wnt/β-catenin 信号传导。 [1,2,4]三唑并[4,3- b ]pyradizin-3(2 H )-one系列4代表了Notum抑制剂的一种新化学类型,也是VS活动中第一个发现的。这些结果证明了 VS 与基于 X 射线结构的精心设计的对接模型的价值。
