A series of novel isocoumarin derivatives were synthesized using Castro–Stephens cross-coupling. Moreover, novel 3,4-dihydroisocoumarin derivatives were obtained by catalytic hydrogenation of the corresponding isocoumarin precursors. The antiproliferative activity of all compounds was evaluated in vitro in different tumor cells. Furthermore, docking calculations were performed for the kallikrein 5
使用Castro-Stephens交叉偶联合成了一系列新型异香豆素衍生物。此外,通过相应的异香豆素前体的催化氢化获得了新的3,4-二氢异香豆素衍生物。在不同的肿瘤细胞中体外评估了所有化合物的抗增殖活性。此外,对激肽释放酶5(KLK5)活性位点进行了对接计算,以预测该系列化合物的可能作用机理。理论发现表明3,4-二氢异香豆素衍生物10a与KLK5的Ser190和Gln192残基形成氢键。该衍生物是该系列中活性最高的化合物,具有强大的抗增殖活性和高选择性指数(SI> 378.79)对抗乳腺癌细胞(MCF-7,GI 50 = 0.66μgmL -1)。该化合物代表了开发新的抗增殖剂的有希望的基质。
