生物活性:
CS1 is a potent DNA Topo II α inhibitor. CS1 displays broad-spectrum in vitro antitumor effects, low toxicity in vivo and potential anti-multidrug resistance capabilities. CS1 leads to DNA damage, cell cycle arrest at G2/M phase and apoptosis.

体内研究:
CS1 (20 mg/kg; i.v.; every other day for two weeks) shows antitumor effects.Animal Model:Five-week-old female athymic nude mice (BALB/c-nu)
Dosage:20 mg/kg
Administration:i.v., every other day for two weeks
Result:Showed antitumor effects.

体外研究:
CS1 shows cytotoxicity with IC50 values of 16.92 and 18.88 μM for MCF-7 and MCF7/ADR cells, respectively. CS1 (10, 50, 100 μM) inhibits the activity of topoisomerase II α (Topo IIα).CS1 (0-20 μM) shows antiproliferation activity in cancer cells.CS1 (2.5, 5, 10 μM) induces cell cycle arrest at the G2/M phase.CS1 (2.5, 5, 10 μM) induces cell apoptosis.CS1 (5, 10, 15 μM; 24 h) induces DNA breaks in MDA-MB-231 cells.
