Biological Activity

3,29-O-dibenzoyloxykarounidiol is a natural triterpenoid derivative isolated from Trichosanthes kirilowii Maxim that exhibits antitumor-promoting and cytotoxic properties. It inhibits 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced Epstein-Barr virus early antigen activation and displays potent inhibitory activity against cancer cell growth. Through these mechanisms, the compound suppresses cell proliferation and promotes apoptotic cell death in human cancer model systems. [1]

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
