Effect of Cepharanthine on the Cytotoxicity of Doxorubicin in Human B-Lymphoma Cells
Keywords:
anticancer, chemotherapeutic drugs, cepharanthine, lymphomaAbstract
In this study, we investigated the activity of cepharanthine (CEP), doxorubicin, and combination on cytotoxicity and apoptosis using human lymphoma Ramos cells. Cells were treated with doxorubicin alone or in combination with CEP (10, 20 and 40 µM). Cytotoxic and apoptosis studies were done after 24 h incubations. CEP had cytotoxicity on cells with an IC50 value of 13.77 µM. CEP at concentrations of 10, 20 and 40 µM additively increased the cytotoxic and the apoptotic effects of doxorubicin, leading to a decrease in IC50 (µM) of the drug from 2.55 to 2.20, 1.85 and 1.20, respectively. CEP potentiated cytotoxicity of doxorubicin by increasing apoptotic effects. We conclude that CEP may have beneficial effects in patients with B cell lymphoma treated with chemotherapy.
