Tyrosyl-tRNA synthetase (TyrRS) is an aminoacyl-tRNA synthetase family protein that possesses an essential role in bacterial protein synthesis. The synthesis, structure-activity relationship, and evolution of a novel series of adenosine-containing 3-arylfuran-2(5H)-ones as TyrRS inhibitors are described. Advanced compound d3 from this series exhibited excellent affinity for TyrRS with IC50 of 0.61
酪氨酰-tRNA合成酶(TyrRS)是一种氨酰基-tRNA合成酶家族蛋白,在细菌蛋白合成中具有重要作用。描述了一系列新型的含腺苷的3-芳基呋喃-2(5H)-酮作为TyrRS抑制剂的合成,结构-活性关系和演变。该系列的先进化合物d3对TyrRS表现出优异的亲和力,IC50为0.61±0.04μM。细菌生长抑制试验表明,d3对大肠杆菌和铜绿假单胞菌显示出亚微摩尔抗菌力,并且与市售的环丙沙星抗生素相比。
