Popis: Addressing multidrug resistant stage of breast cancer is an impediment for chemotherapy. Moreover, breast cancer chemotherapy has potential enduring confrontations i.e. related toxicity including effect on fertility of young female patients. The co-delivery of polyphenolic bio-enhancers with oleanolic acid in chitosan coated PLGA nanoparticles was designed for oral delivery with enhanced antitumor effect consecutively preserving the female fertility. The optimized oleanolic- bio-enhancer nano formulation CH-OA-B-PLGA with particle size was 342.2±3.7nm and zeta potential of 34.2±3.1mV was capable of lowering viability in MDAMB 231 cell line 16 times than OA. Further, mechanistic studies in MDAMB-231 cells revealed that CH-OA-PLGA induces apoptosis by mitochondrial membrane disruption; follows ROS mediated and caspase dependent apoptosis. The antitumor effect studied in 4-T1 induced Balb/c mice mammary tumor model displayed augmented antitumor potency by CH-OA-B-PLGA in comparison to OA. In the in vivo toxicity on Sprague-Dawley rat model, CH-OA-B-PLGA significantly displayed the safe profile and also preserves fertility in female rats. The experiment result suggests co-delivery of oleanolic acid with bio-enhancers as a breakthrough for developing safe chemotherapy for hormone independent breast cancer therapy countering the toxicity issues.
