structural complexity and pharmacological activity. Among these, 9H-pyrido[2,3-b]pyrrolizin-9-one, tripentone analogs, recently reported by us, showed significant antiproliferative activity against human tumor cell lines, inducing apoptosis and not affecting viability of Caco-2 differentiated in normal intestinal-like cells. Considering their interesting biological activity, their 5H-pyrido[3,2-b]pyrrolizin-5-one
吡咯烷酮代表一类有趣的化合物,具有不同程度的结构复杂性和药理活性。其中,最近由我们报道的9 H-吡啶并[2,3- b ]吡咯烷嗪9-一,曲坦酮类似物对人肿瘤细胞系表现出显着的抗增殖活性,诱导细胞凋亡且不影响Caco-2分化的Caco-2的活力。正常的肠样细胞。考虑到它们有趣的生物活性,它们的5 H-吡啶基[3,2- b有效地合成]吡咯烷酮-5-一类似物,产率高至优异(61-91%)。测试所有曲坦酮衍生物以评估其对两种人肿瘤细胞系HCT-116(人结肠直肠癌)和MCF-7(人乳腺癌)的细胞毒性。具有最强活性的衍生物(IC 50为0.11至16.11μM)不影响正常肠样细胞中分化的Caco-2的活力,表明肿瘤细胞是其细胞毒性作用的主要靶标。进一步研究的相同化合物显示它们没有发挥坏死作用,同时诱导了活细胞向早期凋亡的明显转移,从而将细胞限制在有丝分裂期。
