In this paper a simple and efficient method for the unsymmetrical terphenyls via sequential one-pot Suzuki coupling reactions using Pd(OAc)2 without isolation of the intermediate is described. The prepared terphenyls were found to possess potent anticancer properties against a panel of cancer cells which includes A549, HeLa, MCF7, DU145, HT29 and BxPC-3. Structural similarity with combretastatin A4, these terphenyls disrupted the tubulin polymerization in vitro and destabilized the microtubules in cells. Flow cytometry studies indicated growth arrest of cells in the G2/M phase of the cell cycle corresponding to antimitotic action. Furthermore, compound 4c showed potent anti-mitotic activity even in zebrafish model and could likely be a potential therapeutic compound as it is active both in in vitro and in vivo.
本文描述了一种简单有效的方法,通过使用 Pd(OAc)2 的连续一锅 Suzuki 偶联反应来制备不对称三联苯,无需分离中间体。研究发现所制备的三联苯对一组癌细胞具有有效的抗癌特性,其中包括 A549、HeLa、MCF7、DU145、HT29 和 BxPC-3。这些三联苯与考布他汀 A4 结构相似,可破坏体外微管蛋白聚合并破坏细胞中微管的稳定性。流式细胞术研究表明细胞生长停滞在细胞周期的 G2/M 期,这与抗有丝分裂作用相对应。此外,化合物 4c 即使在斑马鱼模型中也显示出有效的抗有丝分裂活性,并且可能是一种潜在的治疗化合物,因为它在体外和体内均具有活性。
