isoprene-derived side chains at the E-ring were designed and synthesized. For comparison, compound 39, with a benzyloxy group on the E-ring, and six D-ring opened analogues, 40-45, were also prepared. All the synthetic compounds were evaluated for their cytotoxic activities in vitro against seven cultured human tumor cell lines. Compounds 27, 43, and 44 were more cytotoxic than etoposide on BEL-7404, A549, and
设计并合成了一系列异戊二烯鬼臼毒素(5)类似物26-38,在E环上带有各种异戊二烯衍生的侧链。为了比较,还制备了在E环上具有苄氧基的化合物39和六个D环开环的类似物40-45。评价所有合成化合物在体外对七种培养的人肿瘤细胞系的细胞毒性活性。在BEL-7404,A549和HL-60细胞系上,化合物27、43和44的细胞毒性分别比依托泊苷高。然而,没有一种合成的异去氧鬼臼毒素比鬼臼毒素具有更强的细胞毒性(1)。
