How to use

In Vitro:

Rubropunctatin (1.5-30 μM; 24 h) shows selective tumoricidal effect on the human gastric carcinoma BGC-823 cells and no significant toxicity toward normal epithelial cell GES-1. Rubropunctatin (5-30 μM; 6-24 h) induces apoptosis in a dose- and time-dependent manner in BGC-823 cells. Rubropunctatin (0.75-8.0 µg/ml) exhibits DDPH radical scavenging activity, inhibition of super oxide radical generation and ferric reducing activity.

In Vivo:

Rubropunctatin (8-32 mg/kg; i.v. for 5 times) has anti-tumor effect mice. Rubropunctamine inhibits 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammation in mice, with an ID50 of 0.11 mg/ear.
