Trihydroxylated Anthocyanins Potentiate Effects of Docetaxel in Mesenchymal Triple Negative Breast Cancer Cells.

ABSTRACT: Triple negative breast cancer (TNBC) presents a significant therapeutic challenge due to its poor prognosis and limited treatment options. While anthocyanins, a group of flavonoids, exhibit promising anticancer potential, their structure-activity relationship and adjuvant properties in TNBC remain underexplored. This study evaluated the anti-proliferative effects of five structurally distinct anthocyani(di)ns-cyanidin-3-O-glucoside (C3G), delphinidin-3-O-glucoside (D3G), delphinidin-3-O-rutinoside (D3R), malvidin-3-O-glucoside (M3G), and luteolinidin (LT)-on mesenchymal TNBC cells. Combination assays of docetaxel (DT), a first-line chemotherapeutic agent, with the most potent anthocyani(di)ns were conducted with TNBC and MCF-12A non-cancerous cells. Trihydroxylated anthocyanins (D3G and D3
