This study aimed at screening of novel aminonaphthoquinone derivatives (Rau 008, Rau 010, Rau 015 and Rau 018) combined with curcumin for cytotoxic, anti-angiogenic and anti-metastatic effects on MCF-7 and MDA-MB-231 breast cancer cells. Materials and Methods: Cytotoxic and anti-angiogenic effects were analysed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and enzyme-linked immunosorbent assay; while anti-metastatic effects were measured using adhesion assay, Boyden chambers and Matrigel. Results: Curcumin combined with Rau 008 elicited marked cytotoxic effects in MCF-7 cells compared with the individual treatments, whereas when it was combined with Rau 015 and with Rau 018, it displayed similar effects in MDA-MB-231 cells. The anti-angiogenic effect of Rau 015 plus curcumin in MCF-7 cells and Rau 018 plus curcumin in MDA-MB-231 cells was more effective than individual treatments, while the metastatic capability of MDA-MB-231 cells was significantly reduced after treatment with the aminonaphthoquinone-curcumin combinations. Conclusion: Aminonaphthoquinones may offer significant promise as therapeutic agents against breast cancer, particularly when combined with curcumin. ER -
