Use of dietary components as antineoplastic agents has been highlighted due to their high biological activity against tumor cells, chemo preventive effects and low toxicity. The present study evaluated antitumor effects and chemo protective potential of Bromelain (BL) alone and in combination with Doxorubicin (DOX) using in vitro tests: Alamar blue in the lines: AGP01, SKMEL103 and CAL27; MTT assay (3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide), fluorescent labelling in murine Sarcoma 180 (S180) and comet assay in human lymphocytes. Cytotoxic effects of BL were noted with IC50 (μg/mL) of 124.80 (AGP01), 91.81 (SKMEL103), 95.75 (CAL27) and 25.27 (S180). When incubated in a BL+DOX combination, they demonstrated combination indices ranging from synergistic to antagonistic. In the cell death mechanism at S180, an increase in the number of cells unde..
