library of compounds based on the structure of goniothalamin (1) and the evaluation of the potential antitumor activity of the compounds. N‐Acylation of aza‐goniothalamin (2) restored the in vitro antiproliferative activity of this family of compounds. 1‐(E)‐But‐2‐enoyl‐6‐styryl‐5,6‐dihydropyridin‐2(1H)‐one (18) displayed enhanced antiproliferative activity. Both goniothalamin (1) and derivative 18 led
在本文中,我们描述了基于goothothalamin(1)结构的化合物的重点文库的合成,以及该化合物潜在的抗肿瘤活性的评估。氮杂goniothalamin的N-酰化(2)恢复这个化合物家族的体外抗增殖活性。1-(E)-但是-2-烯丙基-6-苯乙烯基-5,6-二氢吡啶2-2(1 H)-一(18)显示出增强的抗增殖活性。鞘脂素(1)和衍生物18均可在PC-3细胞中产生活性氧,这可能是胱天蛋白酶依赖性细胞凋亡的信号。用衍生物18处理促进膜联蛋白V / 7-氨基放线菌素D双重染色,这表明细胞凋亡,并导致G 2 / M细胞周期停滞。在Ehrlich腹水和实体瘤模型中进行的体内研究证实了鞘氨醇(1)的抗肿瘤活性,没有毒性迹象。然而,尽管在相同的接种部位进行治疗,衍生物18仍表现出出乎意料的更低的体内抗肿瘤活性。与它的体外情况相反,氮杂吗啡硫胺素(2)抑制了Ehrlich肿瘤的腹水和固体形式的生长。我们
