An intensive long-term investigation of marine organisms as sources of new anticancer drugs has led to the isolation and structural elucidation (primarily by high field NMR and mass spectrometry) of halistatin 2, a new polyether macrolide of the halipyran-type, from the Western Indian Ocean sponge Axinella cf. carteri (Dendy). Halistatin 2 (1.4 x 10-6% yield) caused the accumulation of cells arrested in mitosis, inhibited tubulin polymerization, and inhibited the binding of radiolabeled vinblastine and GTP to tubulin. Further, Halistatin 2 displayed significant activity against selected human tumor cell lines.
Halistatin 2 has the following structural formula :
通过对海洋生物作为新型抗癌药物来源的长期深入研究,我们从西印度洋海绵Axinella cf. carteri (Dendy)中分离并(主要通过高场核磁共振和质谱分析)阐明了一种新型卤代吡喃类聚醚大环内酯--halistatin 2。 Halistatin 2(产率为 1.4 x 10-6%)可导致有丝分裂停止的细胞聚集,抑制微管蛋白聚合,并抑制放射性标记的长春新碱和 GTP 与微管蛋白的结合。 此外,卤司他丁 2 对某些人类肿瘤细胞株具有显著的活性。 卤司他丁 2 的结构式如下::
