  SeThrRS-8g complex revealed that 8g induced a bended conformation for Met332 by forming hydrophobic interactions, which better mimicked the binding of tRNAThr to ThrRS. Moreover, the inhibitory potency of 8g was less impaired than a reported ATP competitive inhibitor at high concentrations of ATP, supporting our hypothesis that tRNA site inhibitors are likely superior to ATP site inhibitors in vivo,

  氨酰基-tRNA合成酶（aaRSs）由于其在蛋白质翻译中的重要作用而成为一类有吸引力的抗菌药物靶标。虽然大多数传统的aaRS抑制剂都靶向底物氨基酸和/或ATP的结合口袋，但我们最近开发了一类新型tRNA-氨基酸双位抑制剂，包括抑制剂3（（2 S，3 R）-2-amino- N -（（E）-4-（6,7-dichloro-4-oxoquinazolin-3（4 H）-yl）but-2-en-1-yl）-3-hydroxybutanamide）反对苏氨酸tRNA合成酶（ThrRS） 。在此，通过肠沙门氏菌ThrRS（Se）的晶体结构分析了这些抑制剂的结合模式和构效关系（SARs）。ThrRS）与其中三个复杂。基于共晶体结构，设计并合成了十二种喹唑啉酮-苏氨酸杂化物，并评估了它们的亲和力，酶抑制活性和细胞效能。最好的衍生物8g的K d值为0.40μM，对Se ThrRS的IC 50值为0.50μ
