  Synthesis and antiproliferative activity of some steroidal lactams

  摘要：

  Using cholesterol as starting material, a series of 6-substituted-3-aza-A-homo-3-oxycholestanes and 6-substituted-4-aza-A-homo-3-oxycholestanes were synthesized by the oxidation, reduction, oximation, Beckman rearrangement and condensation reaction. These synthesized compounds displayed a distinct cytotoxicity against MGC 7901, HeLa and SMMC 7404 cancer cells. Our results revealed that the structures of functional groups at position-6 on the steroidal ring are crucial for the IC50 value of antiproliferative activities of these compounds and the cytotoxic activity against MGC 7901 and SMMC 7404 cells was not significantly different between 4-N-lactams and 3-N-lactams when its 6-substituted group was a carbonyl or a hydroximino, but all 3-N-lactams showed a higher cytotoxicity against HeLa cells than 4-N-lactams. In particular, compounds 6, 8, 9 (IC50 6: 6.5 mu mol/L; 8: 7.7 mu mol/L; 9: 5.6 mu mol/L) were even more cytotoxic than cisplatin to HeLa cells (positive contrast, 10.1 mu mol/L). The information obtained from the studies may be useful for the design of novel chemotherapeutic drugs. (C) 2011 Elsevier Inc. All rights reserved.
