体外研究(In Vitro)
(±)-10-Hydroxycamptothecin (10-OH-camptothecin) is an inhibitor of topo I. (±)-10-Hydroxycamptothecin (10-HCPT, 5-20 nM) markedly inhibits the proliferation of Colo 205 cells in a dose-dependent manner. (±)-10-Hydroxycamptothecin (5-20 nM) arrests Colo 205 cells in the G2 phase of the cell cycle and triggers apoptosis through a caspase-3-dependent pathway. (±)-10-Hydroxycamptothecin (HPT, 0.01-10 μg/mL) causes cell shrinage, nuclear fragmentation and condensed chromosomes and induces apoptosis of human urinary bladder cancer cell line (T24).Medlife has not independently confirmed the accuracy of these methods.

体内研究(In Vivo)
(±)-10-Hydroxycamptothecin (10-HCPT, 2.5-7.5 mg/kg/2 days, p.o.) significantly suppresss tumor growth in mouse xenografts. (±)-10-Hydroxycamptothecin (1-7.5 mg/kg, p.o., once per 2 or 4 days) causes no obvious acute toxicity in nude mice.Medlife has not independently confirmed the accuracy of these methods.
