A novel series of BPU analogues were synthesized and evaluated for antitumor activity. In particular, BPU sulfur analogues 6n and 7d were shown to possess up to 10-fold increased potency, when compared to compound 1, against cancer cell lines. 6n was more effective than compound 1 in causing apoptosis of MCF-7 cells. When compared to other drugs with a similar mechanism of action, 6n retained significant ability to inhibit tubulin assembly, with an IC50 of 2.1 μM.
一系列的BPU类似物被合成并用于抗肿瘤活性评估。特别是BPU硫类似物6n和7d显示出与化合物1相比,对癌细胞系具有高达10倍的增强效力。6n比化合物1更有效地导致MCF-7细胞凋亡。与具有类似作用机制的其他药物相比,6n保持了显著的抑制微管组装的能力,其IC50为2.1μM。
