Sorafenib, a multikinase inhibitor used for the treatment of hepatocellular carcinoma, is limited by its low oral bioavailability. To overcome this drawback, we have developed novel camel milk casein-derived nanoparticles as a drug delivery system. Camel milk casein is not only biocompatible on oral administration but is actually a dietary protein of pharmaceutical relevance. Casein is used because of its amphiphilic nature, self-assembling property, ability to show sustained release, and capability of encapsulating both hydrophilic and hydrophobic drugs. In this study, camel milk casein nanoparticles loaded with sorafenib were developed and characterized. Characterization of casein nanoparticles was done by dynamic light scattering (DLS), zeta potential analysis, scanning light microscopy (SEM), and FTIR. The drug content in nanoparticle and drug-protein binding studies were conducted by UV spectroscopy. The cytotoxicity and cellular uptake efficiency studies were performed in HepG2 cell lines. It was observed that the cytotoxic effect of sorafenib loaded camel milk casein nanoparticles was more than free sorafenib in HepG2 cells. This work suggests camel milk casein as a suitable drug delivery molecule for sorafenib. In the future, it may also be used in enhancing the efficacy and specific distribution of other water-insoluble anticancer drugs. |
