Structure Modification of Ginsenoside Rh₂ and Cytostatic Activity on Cancer Cells.

ABSTRACT: Ginsenoside Rh₂ (Rh₂) is one of the most effective anticancer components extracted from red ginseng, but the poor solubility limits its clinical application. In this paper, ginsenoside Rh₂ was modified with maleimidocaproic acid or maleimidoundecanoic acid with functional groups at both ends. The structures of derivatives were determined by analysis of 1D and 2D nuclear magnetic resonance, Fourier transform infrared, and high-resolution mass spectrometry. Antiproliferative cell experiments showed that Rh₂ modified with maleimidocaproic acid (C-Rh₂) displayed higher cytostatic activity against different tumor cells compared with Rh₂, while Rh₂ modified with maleimidoundecanoic acid (U-Rh₂) did not exhibi
