3α,7α-Dihydroxy-5-epiaragusterol A (3) was synthesized from bile acid (cholic acid) as a new steroidal nuclear analogue of antitumor marine steroid aragusterol A. 7α-Hydroxyaragusterol A (4) was also derived from xestokerol B. The in vitro anti-proliferative activity of each of these analogues toward KB cells as well as in vivo anti-tumor activity of 5-epiaragusterol A (2) previously synthesized by the authors and 3 were assessed.
3α,7α-二羟基-5-表阿古甾醇A(3)是从胆酸(胆酸)合成的一种新型甾体核心类似物,作为抗肿瘤海洋甾体阿古甾醇A的类似物。7α-羟基阿古甾醇A(4)也源自黄麻甾醇B。评估了这些类似物对KB细胞的体外抗增殖活性和作者先前合成的5-表阿古甾醇A(2)及3的体内抗肿瘤活性。
