Prostate cancer is the fifth most common neoplasm worldwide, and the second most common cancer among men. Ginsenosides, the main component of ginseng, have been known for their medicinal effects such as anti-inflammatory and anti-proliferative activities. In this study, we investigated the inhibitory effects of ginsenosides (ginsenoside 20(R)-Rh2 and ginsenoside 20(S)-Rh2) on prostate cancer cells in vitro. Only ginsenoside 20(S)-Rh2 showed proliferation inhibition on androgen-dependent and -independent prostate cancer cells. These results implied that the stereochemistry of the hydroxyl group at C-20 may play an important role in antitumor activities.
