Millepachine is a natural product found in the Chinese herbal medicine with strong antitumor effects against numerous human cancer cells.(In Vitro):Millepachine (2-8 μM; 24 h) inhibits ATP-binding cassette transporter activity in A2780CP cells. Millepachine (2-8 μM; 24 or 48 h) induces significant G2/M arrest and apoptosis of cisplatin-sensitive A2780S and cisplatin-resistant A2780CP cells. The percentage of cells in the G2/M fraction increased from 15.99% in vehicle cells to 24.93%, 60.67%, and 77.31% at dose of 2, 4, and 8 μM in A2780S cells, respectively. Millepachine (2-8 μM; 24 h) decreases topoisomerase II levels in A2780S and A2780CP cells. Millepachine (1.25-20 μM; 48 h) remarkably inhibits the proliferation of cisplatin-resistant A2780CP cells with an IC50 of 4 μM.(In Vivo):Millepachine (20 mg/kg; i.v.) reduced tumor volume and tumor weight with the inhibitory rate of 73.21% and 65.58% in A2780S and A2780CP xenograft models, respectively. Millepachine does not induce acquired drug resistance in an excised A2780S xenograft model.

Millepachine (20 mg/kg; i.v. every two days for 14 day) inhibits tumor growth in mice.Millepachine (20 mg/kg; i.v. every two days for 14 day) does not induce acquired drug resistance in an excised A2780S xenograft model. Animal Model:Female BALB/c nude mice (6 weeks) are injected A2780S or A2780CP cells Dosage:20 mg/kg Administration:I.v. every two days for 2-14 days Result:Reduced tumor volume and tumor weight with the inhibitory rate of 73.21% and 65.58% in A2780S (after seven times injection) and A2780CP (after six times injection) xenograft model, respectively.
