The synthesis of a newangular analog 11 of cyclozonarone was achieved via Diels-Alder reaction between a sesquiterpene-1,3-diene and 1,4-benzoquinone. The cytotoxic activity of ent-cyclozonarone [(+)-10] and the angular (−)-cyclozonarone analog 11 has been determined in three human cancer cell lines and in normal fibroblasts using the sulforhodamine B assay. The analyzed isomers induce cell death in different cancer cell lines by eliciting nuclear condensation and fragmentation, decreasing mitochondrial membrane permeability and increasing caspase-3 activity, all traits indicating apoptosis, with the effects of (+)-10 being stronger than those of 11 in all cases.
通过倍半萜-1,3-二烯和1,4-苯醌之间的Diels-Alder反应合成了环佐酮的新角类似物11。已使用磺胺罗丹明 B 测定在三种人类癌细胞系和正常成纤维细胞中测定了对角环佐那隆 [(+)-10] 和角型 (-)-环佐那隆类似物 11 的细胞毒活性。分析的异构体通过引发核浓缩和断裂、降低线粒体膜通透性和增加 caspase-3 活性,在不同癌细胞系中诱导细胞死亡,所有特征都表明细胞凋亡,其中 (+)-10 的作用强于 11 的作用。所有情况。
