Novel semisynthetic coumarin derivatives were synthesized to be developed as chemotherapeutic anticancer agents through topoisomerase II, VEGFR2 inhibition that leads to apoptotic cancer cell death. The coumarin amino acids and dipeptides derivatives were prepared by the reaction of coumarin-3-carboxylic acid with amino acid methyl esters following the N,N-dicyclohexylcarbodiimide (DCC) method and
合成了新型半合成香豆素衍生物,通过拓扑异构酶 II、VEGFR2 抑制导致癌细胞死亡,将其开发为化疗抗癌剂。采用N,N-二环己基碳二亚胺(DCC)法,以1-羟基-苯并三唑(HOBt)为偶联剂,通过香豆素-3-羧酸与氨基酸甲酯的反应制备香豆素氨基酸和二肽衍生物。合成的化合物针对 VEGFR2 和拓扑异构酶 IIα 蛋白进行筛选,以突出它们的结合亲和力和虚拟结合机制。有趣的是,化合物 4k (Tyr) 和 6c (β-Ala-L-Met) 通过与关键氨基酸(如共结晶配体)形成相同的相互作用而共享对三种蛋白质的活性。化合物 4k 和 6c 均对 MCF-7 细胞表现出有效的细胞毒活性,IC50 值为 4.98 和 5.85 µM,分别导致细胞死亡 97.82% 和 97.35%。验证分子对接研究,与索拉非尼 (30 µM) 相比,两种化合物均表现出良好的 VEGFR-2 抑制作用,IC50 值为
