series of 4,5-diaryl-3H-1,2-dithiole-3-thiones and related compounds were designed and synthesised as combretastatin A-4/oltipraz hybrids. We evaluated the antiproliferative activities, inhibition of tubulin polymerization, and cell-cycle effects of these compounds. Several compounds in this series, such as 4d and 5c, displayed significant activity against SGC-7901, KB and HT-1080 cell lines, as determined
设计并合成了一系列新的4,5-二芳基-3 H -1,2-二硫基-3-硫酮和相关化合物,作为康布雷他汀A-4 / oltipraz杂种。我们评估了这些化合物的抗增殖活性,对微管蛋白聚合的抑制作用以及细胞周期效应。使用MTT分析测定,该系列中的几种化合物(例如4d和5c)显示出对SGC-7901,KB和HT-1080细胞系的显着活性。活性最高的化合物4d显着抑制微管蛋白聚合,观察到IC 50值为4.44μM。在力学研究中,4d导致细胞停滞在G2 / M期,诱导凋亡细胞死亡,并破坏微管形成。分子对接研究表明4d与微管蛋白有效相互作用并结合。
