Herein, we report the synthesis of a novel class of substituted androst[17,16-b]pyridines (pyridosteroids) from the reaction of β-formyl enamides with alkynes in high yields. The optimized reaction protocol was extended to acyclic and cyclic β-formyl enamides to afford nonsteroidal pyridines. Cell survival assay of all compounds were carried against prostate cancer PC-3 cells wherein 3-hydroxy-5-en-2′
本文中,我们报道了从β-甲酰基酰胺与炔烃的高收率反应中合成一类新型的取代的[17,16- b ]吡啶(吡啶类固醇)。优化的反应方案扩展到无环和环状β-甲酰胺,以提供非甾体吡啶。对前列腺癌PC-3细胞进行所有化合物的细胞存活测定,其中3-羟基-5-en-2′,3′-二甲乙氧基-雄酮[17,16- b ]吡啶显示出最高的细胞毒活性。相差显微镜和流式细胞术研究显示了在3-hydroxy-5-en-2',3'-dicarbethoxy-androst [17,16- b ]吡啶和阿比特龙处理的PC-3细胞中凋亡的显着形态学特征。3-hydroxy-5-en-2',3'-dicarbethoxy-androst [17,16-b ]吡啶诱导前列腺癌PC-3细胞中G 2 / M期细胞周期停滞。3-羟基-5-en-2',3'-二碳乙氧基-雄酮[17,16- b ]吡啶和阿比特龙通过激活caspases-
