  Synthesis of macrocyclic bisbibenzyl derivatives and their anticancer effects as anti-tubulin agents

  摘要：

  Based on the core skeleton of the total synthesized bisbibenzyl marchantin C, riccardin D and plagiochin E, a series of brominated and aminomethylated derivatives of above three bisbibenzyls have been synthesized and their cytotoxic activity against KB, MCF-7 and PC3 cell lines has been preliminary evaluated. The bio-test results revealed that the brominated derivatives 21, 22, 24, 25 and 28 exhibited excellent antiproliferative activity, with IC50 value lower than their parent compounds. As a most potent microtubule depolymerization agent, compound 28 was found to arrest cells at the G(2)/M phase of the cell cycle as determined by the flow cytometry assay in PC3 cell line. The remarkable biological profile and novel structure of these bisbibenzyl derivatives make them possible as promising candidates for clinical development as chemotherapeutic agents.

  from Marchantia polymorpha, a liverwort. The total synthesis of the proposed structure for plagiochin E and of two structurally and biosynthetically related bisbibenzyls and comparison of the NMR data of the synthetic compounds with those of the isolated bisbibenzyls necessitates a structure revision for plagiochin E. Exemplarily for this metabolite, the stereostructure was investigated, by racemate

  最近，一种名为 plagiochin E 的双苄基显示出显着的抗真菌和抗肿瘤活性，从地钱地衣中分离出来。plagiochin E 和两种结构和生物合成相关的双苄基的拟议结构的全合成以及合成化合物的 NMR 数据与分离的双苄基的 NMR 数据的比较需要对 plagiochin E 进行结构修正。 例如，对于这种代谢物，立体结构是通过对手性 Lux Cellulose-1 相的外消旋体拆分进行研究，使用 HPLC-CD 偶联和量子化学 CD 计算，清楚地将 P 构型分配给较快的对映体，将 M 构型分配给较慢的对映体。
