  Synthesis and cytotoxic activity of diosgenyl saponin analogues

  摘要：

  Diosgenyl saponins are steroidal glycosides that are often found as major components in many traditional oriental medicines. Recently, a number of naturally occurring diosgenyl saponins have been shown to exert cytotoxic activity against several strains of human cancer cells. Use of these saponin compounds for cancer treatment is hampered due to the lack of understanding of their action mechanism as well as limited access to such structurally complicated molecules. In the present paper, we have prepared a group of diosgenyl saponin analogues which contain a beta-D-2-amino-2-deoxy-glucopyranose residue having different substituents at the amino group. Moderate cytotoxic activity is found for most analogues against neuroblastoma (SK-N-SH) cells, breast cancer (MCF-7) cells, and cervical cancer (HeLa) cells. The analogue 13 that contains an alpha-lipoic acid residue exhibits the highest potency against all three cancer cell lines with IC50 ranging from 4.8 mu M in SK-N-SH cells to 7.3 mu M in HeLa cells. Preliminary mechanistic investigation with one saponin analogue (10) shows that the compound induces cell cycle arrest at G(1) phase in SK-N-SH cells, but the same compound induces cell cycle arrest at G(2) phase in MCF-7 cells. This result suggests that the cytotoxic activity of these saponin analogues may involve different action mechanisms in cell lines derived from different cancer sites. (C) 2007 Elsevier Ltd.
