physiological conditions, reducing the overall activity of the drug candidates. Herein, we report the preparation of cis-restrained carbocyclic analogs of CA-4. The compounds, which differ by the size and hybridization of the carbocyclic ring have been evaluated for their cytotoxic properties and their ability to inhibit tubulin polymerization. Biological data, supported by molecular docking studies, identified
Combretastatin A-4(CA-4)是一种高度细胞毒性的天然产物,已经制备了几种衍生物,并已进行了临床试验。这些研究表明,天然产物的顺式-lb部分在生理条件下易于进行顺式/反式异构化,从而降低了候选药物的总体活性。在这里,我们报告顺式的制备约束的CA-4碳环类似物。已经评估了因碳环的大小和杂交而异的化合物的细胞毒性和抑制微管蛋白聚合的能力。在分子对接研究的支持下,生物学数据确定了天然产物的环丁烯基和环丁基衍生物是高度有前途的候选药物。
