10a–g, designed exploiting a structure-based optimization of the previously developed inhibitor CLM3. Compared to the lead, the novel compounds markedly improved both their inhibitory profile against the target proteins, VEGFR2 and RET, and their antiproliferative efficacy against the medullary thyroid cancer cell line TT. Significantly, compounds 8b, 9c, and 10c proved to block the kinase activity of
甲状腺癌发展知识的最新进展将受体酪氨酸激酶(如VEGFR2和RET)确定为可行且有希望的靶标。因此,它们的抑制作用正在成为治疗这些病理的主要治疗策略。在这项研究中,我们描述了三个不同系列的4-取代的吡唑并[3,4- d ]嘧啶衍生物8a – g,9a – g和10a – g的合成和功能评估,它们是基于结构优化设计的先前开发的抑制剂CLM3。与铅相比,新化合物显着改善了它们对靶蛋白,VEGFR2和RET的抑制特性,以及它们对甲状腺髓样癌细胞系TT的抗增殖功效。值得注意的是,化合物8b,9c和10c被证明可以阻断仍然缺乏有效抑制剂的RET V804L突变体的激酶活性。
