To our knowledge, it has been the first example of a conjugated mTOR/MEK bifunctional inhibitor. In addition, from this proof-of-principle study, it has become evident that the single-agent dual inhibition of mTOR and MEK can be fulfilled via covalently attaching mTOR kinase inhibitor to an allosteric MEK inhibitor.
mTOR / MEK双功能抑制剂具有克服PI3K / Akt / mTOR(PAM)与Ras / MEK / ERK途径之间的串扰引起的耐药性的潜力。在本文中,我们报告了共轭双靶分子化合物13作为原型mTOR / MEK双功能抑制剂的发现。它显示出对mTOR和MEK1的适度高抑制活性,IC 50值分别为0.19μM和0.98μM。特别是,它对A549(GI 50 = 4.66μM)和HCT116(GI 50)均表现出有吸引力的抗增殖活性 = 5.47μM)细胞系。据我们所知,它是mTOR / MEK共轭双功能抑制剂的第一个实例。此外,从这项原理验证研究中,很明显,可以通过将mTOR激酶抑制剂共价连接至变构MEK抑制剂来实现mTOR和MEK的单剂双重抑制。
