Leucyl-tRNA synthetase (LRS) plays an important role in amino acid-dependent mTORC1 signaling, which is known to be associated with cellular metabolism and proliferation. Therefore, LRS-targeting small molecules that can suppress mTORC1 activation may provide an alternative strategy to current anticancer therapy. In this work, we developed a library of leucyladenylate sulfate analogues by extensively
Leucyl-tRNA合成酶(LRS)在氨基酸依赖性mTORC1信号传导中起重要作用,已知该信号与细胞代谢和增殖有关。因此,可以抑制mTORC1激活的靶向LRS的小分子可以为当前的抗癌治疗提供替代策略。在这项工作中,我们通过广泛修饰包括腺嘌呤,核糖和亮氨酸的三个不同药效学区域,开发了硫酸亮环烯丙酸酯类似物的文库。通过基于细胞的mTORC1活化分析鉴定了几种有效的化合物,并进一步测试了其抗癌活性。选定的化合物大部分对五种不同的癌细胞系表现出选择性的细胞毒性,支持以下假设:LRS介导的mTORC1途径是当前治疗方法的有希望的替代靶点。
