A series of novel benzothiazole-2-thiol derivatives were synthesized and their structures determined by 1H-NMR, 13C-NMR and HRMS (ESI). The effects of all compounds on a panel of different types of human cancer cell lines were investigated. Among them, pyridinyl-2-amine linked benzothiazole-2-thiol compounds 7d, 7e, 7f and 7i exhibited potent and broad-spectrum inhibitory activities. Compound 7e displayed the most potent anticancer activity on SKRB-3 (IC50 = 1.2 nM), SW620 (IC50 = 4.3 nM), A549 (IC50 = 44 nM) and HepG2 (IC50 = 48 nM) and was found to induce apoptosis in HepG2 cancer cells.
研究人员合成了一系列新型苯并噻唑-2-硫醇衍生物,并通过 1H-NMR、13C-NMR 和 HRMS (ESI) 确定了它们的结构。研究了所有化合物对不同类型人类癌细胞株的影响。其中,与苯并噻唑-2-硫醇相连的吡啶基-2-胺化合物 7d、7e、7f 和 7i 具有强效、广谱的抑制活性。化合物 7e 对 SKRB-3(IC50 = 1.2 nM)、SW620(IC50 = 4.3 nM)、A549(IC50 = 44 nM)和 HepG2(IC50 = 48 nM)的抗癌活性最强,并能诱导 HepG2 癌细胞凋亡。
