commercial anticancer drug 5-FU. In particular, compound 8k appeared to be the most potent compound against the HepG2 cell line, at least partly, by inhibition of the activity of MMP-3 and apoptosis induction. The treatment of HepG2 cells with compound 8k resulted in inhibition of in vitro cell migration through wound healing assay and G1 phase of cell cycle arrested. In addition, 8k-induced apoptosis was
设计,合成和评估了一系列含有磺酰胺部分的脱氢松香酸(DHAA)二肽衍生物,以抑制MMP以及体外细胞迁移的作用。这些化合物对MMP表现出相对良好的抑制活性,IC 50值在低微摩尔范围内。对活性最高的化合物8k的对接研究表明,8k与MMP-3之间存在关键的相互作用,其中磺酰胺部分和二肽基团对于提高活性非常重要。值得注意的是,进一步的抗肿瘤活性筛选显示,某些化合物比商用抗癌药物5-FU表现出更好的抑制活性。特别是化合物8k似乎至少部分地通过抑制MMP-3的活性和诱导细胞凋亡而成为对抗HepG2细胞系最有效的化合物。用化合物8k处理HepG2细胞可通过伤口愈合试验抑制体外细胞迁移,并阻止细胞周期的G1期。另外,在HepG2细胞中明显促进了8k诱导的凋亡。因此,我们得出结论,含有磺酰胺部分的DHAA二肽衍生物可能是具有抑制细胞迁移能力的潜在MMPs抑制剂。
