Enhancement of in vitro activity against neuroblastoma by doxorubicin and deferoxamine.

A colorimetric assay was used to compare the in vitro effects on neuroblastoma cell viability of 3.75-60 microM deferoxamine or 0.125-2 microM doxorubicin alone with those of the two drugs in combination. For each of two human neuroblastoma cell lines (CHP 100 and CHP 126), exposure to each drug individually produced dose-related cytotoxic effects within 3… CONTINUE READING
