Starting from (22E)-3alpha,5alpha-cyclo-6beta-methoxystigmast-22-ene eighteen derivatives of (22S,23S)-22,23-oxidostigmastane, (22R,23R)-22,23-oxidostigmastane, and (22R,23R)-22,23-dihydroxystigmastane were synthesized and screened for cytotoxicity in human hepatoma Hep G2 cells and human breast carcinoma MCF-7 cells using MTT assay. Four compounds of this series exhibited high cytotoxicity in both cells; three compounds were selectively toxic in MCF-7 cells, one compound was toxic in Hep G2 cells, rather than in MCF-7 cells; four compounds at low concentrations increased MTT test values over the control.
以(22E)-3α,5α-环-6β-甲氧基豆甾-22-烯为起始原料，合成了(22S,23S)-22,23-氧化豆甾烷、(22R,23R)-22,23-氧化豆甾烷和(22R,23R)-22,23-二羟基豆甾烷的18种衍生物，并采用MTT法在人肝癌Hep G2细胞和人乳腺癌MCF-7细胞中对其细胞毒性进行了筛选。该系列中的4种化合物在两种细胞中均表现出高细胞毒性；3种化合物在MCF-7细胞中具有选择性毒性，1种化合物在Hep G2细胞中具有毒性，而在MCF-7细胞中无毒性；4种低浓度化合物的MTT测试值高于对照组。
