  Cholest-4 alpha-methyl-7-en-3 beta-ol (1) has potent inhibitory activity against pc 12 tumor with 0.5043 ratio (10 mu g/mL). This paper describes a series of structural modification of this compound, which focus on 3 beta-hydroxyl group and 7(8)-double bond. The synthesized derivatives of I were tested for human cancer cell lines including colon cancer (HCT-8), liver cancer (BEL-7402) and nasopharyngeal cancer (KB) cells. The results showed that cholest-4 alpha-methyl-8-en-3 beta,7 alpha-diol 6a inhibits KB cell significantly with IC50 1.32 x 10(-9) mu g/ml. In addition, the cytotoxic properties of this compound against HCT-8 and BEL-7402 are excellent with IC50 1.2 mu g/mL. (c) 2006 Elsevier Inc. All rights reserved.
