Relative anti-neoplastic potency of covalent epirubicin-(C3-amide)-[anti-HER2/neu] immunochemotherapeutic synthesized utilizing a UV-photoactivated epirubicin-(C3-amide) intermediate compared to anti-HER2/neu monoclonal immunoglobulin against chemotherapeutic-resistant SKBr-3 mammary adenocarcinoma. (▴) covalent epirubicin-(C3-amide)-[anti-HER2/neu] immunochemotherapeutic; and (♦) anti-HER2/neu monoclonal antibody. Monolayers of mammary adenocarcinoma SKBr-3 populations were incubated with the epirubicin immunochemotherapeutic and anti-HER2/neu monoclonal immunoglobulin fraction over a 72-hour period. Cytotoxicity anti-neoplastic potency was measured as a function of MTT cell vitality stain intensity relative to matched negative reference controls.
