Özet
Chemotherapy agents often exhibit limited effectiveness due to their fast elimination from the body and nontargeted delivery. Emerging nanomaterials as drug delivery carriers open new expectancy to overcome these limitations in current chemotherapeutic treatments. In this study, we introduce and evaluate a smart pHresponsive niosomal formulation capable of delivering Doxorubicin (DOX) and Curcumin (CUR) in both individually and co-loaded forms. In particular, drug-loaded niosomes were prepared using thin-film hydration method and then characterized via different physicochemical analyses. The pH responsivity of the carrier was assessed by performing a drug release study in three different pH conditions (4, 6.5, and 7.4). Finally, the anticancer efficacy of the therapeutic compounds was evaluated through the MTT assay. Our results showed spherical particles with a size of about 200 nm and -2 mV surface charge. Encapsulation efficiency (EE%) of the nanocarrier was about 77.06 % and 79.08 % for DOX and CUR, respectively. The release study confirmed the pH responsivity of the carrier. The MTT assay results revealed about 39 % and 43 % of cell deaths after treatment with cur-loaded and dox-loaded niosomes, which increased to 74 % and 79 % after co-administration and coloading forms of drugs, respectively, exhibiting increased anticancer efficacy by selectively delivering DOX and CUR individually or in combination. Overall, these findings suggest that our nanoformulation holds the potential as a targeted and highly effective approach for cancer management and therapy, overcoming the limitations of conventional chemotherapy drugs.
