According to recent studies, leucyl-tRNA synthetase (LRS) acts as a leucine sensor and modulates the activation of the mammalian target of rapamycin complex 1 (mTORC1) activation. Because overactive mTORC1 is associated with several diseases, including colon cancer, LRS-targeted mTORC1 inhibitors represent a potential option for anti-cancer therapy. In this work, we developed a series of simplified leucyladenylate
根据最近的研究,亮氨酰-tRNA合成酶(LRS)充当亮氨酸传感器,并调节哺乳动物雷帕霉素复合物1(mTORC1)靶标的激活。由于过度活跃的mTORC1与包括结肠癌在内的多种疾病有关,因此靶向LRS的mTORC1抑制剂代表了抗癌治疗的潜在选择。在这项工作中,我们开发了一系列简化的亮氨苄基磺酸盐类似物,其中包含N-(3-氯-4-氟苯基)喹唑啉-4-胺部分来取代腺嘌呤基团。我们鉴定了几种与先前报道的抑制剂具有可比活性的化合物,并表现出选择性的mTORC1抑制和抗癌活性。这项研究进一步支持以下假设:LRS是调节mTORC1途径的有希望的靶标。
