Abstract excerpt
We studied the effect of the antimalarial drug mefloquine on the resistance of K562 cells to doxorubicin. Mefloquine synergistically potentiated the cytotoxicity of doxorubicin for doxorubicin-resistant K562 cells (K562/DXR) at a concentration of 0.5-3 microM, but had hardly any synergistic effect in the parental cell line (K562) at the same concentration. Mefloquine was more potent than verapamil, a known...
