SPIKET-P, a novel synthetic spiroketal pyran, was rationally designed as a pharmocophore for the tubulin depolymerizing marine natural product Spongistatin 1. SPIKET-P was prepared from the commercially available benzyl (R)-(-)-glycidyl ether using a versatile 11-step synthetic scheme in a stereocontrolled fashion. At nanomolar concentrations, SPIKET-P caused tubulin depolymerization in cell-free turbidity
SPIKET-P是一种新颖的合成螺环吡喃,被合理地设计为微管蛋白解聚海洋天然产物Spongistatin 1的药物载体。SPIKET-P由市售的苄基(R)-(-)-缩水甘油醚使用通用11立体声控制的逐步合成方案。在纳摩尔浓度下,SPIKET-P在无细胞浊度测定中引起微管蛋白解聚,并表现出对癌细胞有效的细胞毒活性,这可通过破坏微管组织和防止人类乳腺癌细胞中有丝分裂纺锤体形成来证明。
