A series of 3-substituted-6-aza-B-homo-5-α-stigmastan-7-one and 3-substituted-6-aza-B-homo-5-α-sitostan-7-one derivatives were designed and synthesized by the oxidation, reduction, oximation, Beckman rearrangement and condensation reaction. Their structures were characterized. The antiproliferative activities were assayed, and some of the compounds synthesized displayed distinct cytotoxicity against
设计了一系列3-取代的6-氮杂-B-homo-5-α-stigmastan-7-one和3-取代的6-氮杂-B-homo-5-α-sitostan-7-one衍
生物,由氧化,还原,
肟化,贝克曼重排和缩合反应合成。他们的结构被表征。测定了抗增殖活性,合成的某些化合物对SGC 7901,CNE,HeLa和Bel 7404癌细胞显示出明显的细胞毒性。我们的结果表明,具有
谷甾醇侧链的化合物比具有
豆甾醇的侧链的化合物具有更好的抗增殖活性。具有3-thiosemicarbazone组的化合物11b和具有3-(4'-甲基)thiosemicarbazone组的化合物12b对具有IC的Bel-7404细胞显示出优异的抗增殖活性50值分别为3.9和5.6μM(与
顺铂相比,IC 50:11.6μM)。从研究中获得的信息可能对设计新型化疗药物有用。
