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(More)
Using cholesterol, stigmasterol and sitosterol as starting materials, some 4,6-diaza-A,B-dihomo-steroid bilactams were synthesized via two different synthetic routes by oxidation, reduction, oximation, Beckman rearrangement, etc. The cytotoxic activity of the synthesized compounds against SGC 7901 (human ventriculi carcinoma), Bel-7404 (human liver(More)
