  Indiosides G–K: Steroidal Glycosides with Cytotoxic and Anti-inflammatory Activities from Solanum violaceum

  摘要：

  Five new steroidal glycosides (1-5) and nine known compounds were isolated from Solanum violaceum. Indiosides G (1) and H (2) are spirostene saponins with an iso-type F ring, indioside I (3) is a spirostane saponin, and indiosides J (4) and K (5) are unusual furostanol saponins with a deformed F ring. These structures represent rare naturally occurring steroidal skeletons. The structures of the new compounds, were elucidated using 1D and 2D spectroscopic techniques and acid hydrolysis. Compounds 2, 3, and 7-9 exhibited cytotoxic activity against six human cancer cell lines (HepG2, Hep3B, A549, Ca9-22, MDA-MB-231, and MCF-7) with IC50 values of 1.83-8.04 mu g/mL. Steroidal saponins, 3, 8, and 9, showed inhibitory effects on superoxide anion generatiom with IC50 values of 2.84 +/- 0.18, 0.62 +/- 0.03, and 1.62 +/- 0.59 mu g/mL, respectively. Saponins 8 and 9 also inhibited elastase release with IC50 values of 111.05 +/- 7.37 and 4.04 +/- 0.51 mu g/mL, respectively. Structure-activity relationship correlations of these compounds with respect to cytotoxic and anti-inflammatory effects are discussed.

  Five new steroidal glycosides (1-5) and nine known compounds were isolated from Solanum violaceum. Indiosides G (1) and H (2) are spirostene saponins with an iso-type F ring, indioside I (3) is a spirostane saponin, and indiosides J (4) and K (5) are unusual furostanol saponins with a deformed F ring. These structures represent rare naturally occurring steroidal skeletons. The structures of the new compounds, were elucidated using 1D and 2D spectroscopic techniques and acid hydrolysis. Compounds 2, 3, and 7-9 exhibited cytotoxic activity against six human cancer cell lines (HepG2, Hep3B, A549, Ca9-22, MDA-MB-231, and MCF-7) with IC50 values of 1.83-8.04 mu g/mL. Steroidal saponins, 3, 8, and 9, showed inhibitory effects on superoxide anion generatiom with IC50 values of 2.84 +/- 0.18, 0.62 +/- 0.03, and 1.62 +/- 0.59 mu g/mL, respectively. Saponins 8 and 9 also inhibited elastase release with IC50 values of 111.05 +/- 7.37 and 4.04 +/- 0.51 mu g/mL, respectively.
