ABSTRACT
To investigate the chemosensitizing effect of pyrroledithiocarbomate (PDTC) on daunorubicin in drug-resistant leukemic cells in vitro, MTT method was used to observe the changes of the proliferation of intractable leukemia MNC treated with daunorubicin (30 microg/ml) combined with PDTC (25, 50 or 100 micromol/L). The results showed that inhibiting rate of daunorubicin combined with PDTC(25, 50 or 100 micromol/L) on drug-resistant leukemic cells was significantly higher than that of daunorubicin alone (P < 0.05). Among the three different doses of PDTC, the concentration of 50 micromol/L of PDTC inhibited the proliferation of drug-resistant leukemic cells significantly. In conclusion, PDTC can sensitize anti-tumor effect of daunorubicin in vitro. The concentration of 50 micromol/L of PDTC has stronger chemosensitizing effect on daunorubicin than that of the other concentrations of PDTC (25 micromol/L or 100 micromol/L) in vitro.
