Popis: The new therapeutic solutions for breast cancer treatment are needed, for example, combined therapy consisted of several drugs that characterize different mechanisms of action and modern drug delivery systems. Therefore, we used combination of epothilone B (EpoB) and rapamycin (Rap) to analyze the cytotoxic effect against breast cancer cells (MCF-7; MDA-MB-231). Also, the effect of drugs co-delivered in bioresorbable micelles functionalized with biotin (PLA-PEG-BIO; poly(lactide)-co-poly(ethylene glycol)-biotin) was studied. The comparison of effects of the mixture of free drugs and the micelles co-loaded with EpoB and Rap revealed a significant decrease in the cell metabolic activity and survival. Moreover, the dual drug-loaded PLA-PEG-BIO micelles enhanced the cytotoxicity of EpoB and Rap against the tested cells as compared with the free drugs. The blank PLA-PEG-BIO micelles did not affect the tested cells. We expect that mixture of EpoB and Rap may be promising in breast cancer treatment and PLA-PEG-BIO micelles as carrier of these two drugs can be applicable for successful targeted delivery.
