targeted molecules were evaluated in vivo in a phenotypic sea urchin embryo assay for antimitotic and tubulin destabilizing activity. The most active compounds identified by the in vivo sea urchin embryo assay featured myristicin-derived ring E (4e, 6e, and 8e). These molecules were determined to be more potent than podophyllotoxin. Cytotoxic effects of selected molecules were further confirmed and evaluated
使用欧芹种子油中的烯丙基聚烷氧基苯合成了一系列带有修饰的环B和E的4-氮杂鬼臼毒素衍生物。在表型海胆胚胎试验中体内评估了靶向分子的抗有丝分裂和微管蛋白去稳定活性。通过体内海胆胚胎测定法鉴定出的最具活性的化合物的特征是肉豆蔻酸衍生的环E(4e,6e和8e)。确定这些分子比鬼臼毒素更有效。通过使用A549和Jurkat人类白血病T细胞系的常规测定法进一步证实和评估了所选分子的细胞毒性作用,包括细胞生长抑制,细胞周期停滞,细胞微管破坏和凋亡诱导。B环的修饰产生6-OMe取代的分子8e,其为最具活性的化合物。最后,在Jurkat细胞中,化合物8e诱导了由顶端caspases-2和-9而不是caspase-8介导的caspase依赖性凋亡,这暗示了caspase-9依赖性内在凋亡途径的参与。
