Analysis of the Combinatory Effects of Novel Aminonaphthoquinone Derivatives and Curcumin on Breast Cancer Progression.

Background/aim: We previously reported the potential of aminonaphthoquinone derivatives as therapeutic agents against breast and other oestrogen-responsive tumours when combined with curcumin. 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.

Evaluation of the Effects of Aminonaphthoquinone Derivatives in Combination with Curcumin Against ER-positive Breast Cancer and Related Tumours.

Background/aim: Combination therapies are often explored to treat cancer. The use of curcumin as an adjuvant to current chemotherapies has been reported, whilst aminonaphthoquinones have shown potential as anticancer agents in various tumour cell lines. This study aimed at screening synthetic aminonathoquinone derivatives (Rau 008, Rau 010, Rau 015 and Rau 018) alone and in combination with curcumin for anti-breast cancer activity.
