OBJECTIVE The anti-tumor drug, harringtonine (HT), has been extensively used with satisfactory results in the treatment of acute or chronic myeloid leukemia. Previous studies have shown that the anti-tumor activity of...
Objective To understand the mechanism of the hyperthermia and harringtonine in purging of leukemia cells In Vitro. telomerase activity of HL-60 cells treated by hyperthermia ( 42℃ for one hour) and different concen...

Harringtonine (HT), a kind of anticancer drug isolated from Chinese herb-Cephalotaxus hainanensis Li, can induce apoptosis in promyelocytic leukemia HL-60 cells. With both two-photon laser scanning microscopy and conf...
The effect of Ca 2+ on HT induced apoptosis in HL 60 cells was examined. Characteristics of apoptosis induced by harringtonine (HT) or campothecin (CAM) could not be abolished by extracellular calcium chelator EGTA; h...

Glutathione (GSH) is an intracellular tripeptide thiol which is involved in many physiological activities such as detoxification of electrophiles and peroxide regulation of enzyme activity, transportation of amino aci...
The antiparacitic agent Flubendazole (F) caused a dose-dependent and time-dependent induction of polyploid in C3H1OT cells.At concentrations of 78ug/ml the yield of polyploidcells was 95%.Harringtonine(H),a antineopl...
Harringtonine(H) level in serum was quantified by high-performance liquid chromatographic (HPLC) technique and its pharmacokinetic parameters were determined in 11 patients with ANLL after 4 hours continuous infusion ...
