Three diterpene compounds isolated from the anti-cancer herbal medicine kansui, namely, kansuinin B, 20-OD-ingenol Z, and 20-OD-ingenol E, specifically inhibited the proliferation of isolated embryonic cells from Xenopus embryos. We conducted a cytologic study to determine the mechanism underlying the arrest of the cellular proliferation by these compounds. While kansuinin B and 20-OD-ingenol Z treatment decreased the cell numbers in the S phase and the M phase substages of the cell cycle, 20-OD-ingenol E inhibited mitosis.
