disrupting agents (VDAs) capable of inhibiting microtubule polymerization and histone deacetylases (HDACs) were designed and synthesized using the tubulin polymerization inhibitor TH-0 as the lead compound. Among them, compound TH-6 exhibited the most potent antiproliferative activity (IC50 = 18–30 nM) against a panel of cancer cell lines. As expected, TH-6 inhibited tubulin assembly and increased the acetylation
大多数血管破坏剂(VDA)无法阻止肿瘤边缘血管的再生,导致肿瘤反弹和复发。在此,以微管聚合抑制剂TH-0为先导化合物,设计并合成了一系列能够抑制微管聚合的新型多功能血管破坏剂(VDA)和组蛋白去乙酰化酶(HDAC) 。其中,化合物TH-6对一组癌细胞系表现出最有效的抗增殖活性 (IC 50 = 18–30 nM)。正如所料,TH-6抑制微管蛋白组装并增加 HepG2 细胞中 HDAC 底物蛋白的乙酰化水平。进一步的体内抗肿瘤试验表明TH-6有效抑制肿瘤生长,无明显毒性。更重要的是,TH-6破坏了内部和外周肿瘤脉管系统,这有助于停药后的持续肿瘤抑制作用。总之,对于临床癌症治疗的新方法, TH-6值得进一步研究。
