3′,4′,7-trimethoxyflavonol through a 3- to 5-carbon linker can substantially improve the in vitro antiproliferative potency in three human prostate cancer cell models, but not in two non-neoplastic human epithelial cell models (MCF 10A and PWR-1E). 1-Methylpiperazine, pyrrolidine, and dibutylamine are optimal terminal amine groups that, in combination with a 3- to 5-carbon linker, are notably beneficial
合成了38个3- O-取代-3',4'-二甲氧基黄酮醇和25个3 - O-取代-3',4',7-三甲氧基黄酮醇,用于系统研究3-的结构-活性关系。在三种人类前列腺癌细胞模型中,O-取代的3',4'-二甲氧基黄酮醇。我们的发现表明,通过3至5个碳原子的连接基将适当的氨基掺入3',4'-二甲氧基黄酮醇和3',4',7-三甲氧基黄酮醇的3-OH可以显着改善体外在三种人类前列腺癌细胞模型中具有抗增殖能力,但在两种非肿瘤性人类上皮细胞模型(MCF 10A和PWR-1E)中却没有。1-甲基哌嗪,吡咯烷和二丁胺是最佳的末端胺基,与3至5个碳的连接基结合使用,对3- O-取代的3',4'-二甲氧基黄酮醇的抗增殖能力特别有益。值得注意的是3- O-(4-甲基哌嗪-1-基)丙基-3',4',7-三甲氧基黄酮醇(76)诱导PC-3细胞死亡的方式与3- O-吡咯烷基戊基- 3',4',7-三甲氧基黄酮醇(81)即使它们属于3-
