Abstract
The interaction ability of bovine serum albumin (BSA) with 2,6-divanillylidenecyclohexanone (DVH) as a stable curcumin derivative was investigated using fluorescence and circular dichroism (CD) spectroscopy techniques under simulative physiological conditions (pH = 7.2). Following the obtained results of binding studies, bovine serum albumin nanoparticles (BSANPs) were synthesized and characterized using Fourier transform infrared spectroscopy (FT-IR), filed emission scanning electron microscopy (FE-SEM), atomic force microscope (AFM) and dynamic light scattering (DLS). The stable BSANPs showed a spherical shape with a diameter of 149.14 ± 46.69 nm and the formulation of BSA had no change during the fabrication process. DVH was loaded on BSANPs (DVH@BSANPs) and the release studies showed sustained release of DVH from BSANPs. The validation of DVH@BSANPs system confirmed that the Fickian release mechanism of DVH followed on Korsmeyer–Pepas model. The in vitro studies on HFFF2 and MDA-MB-231 were investigated using MTT assay, DAPI and annexinV/PI staining that showed biocompatible BSANPs reduced the cytotoxicity of DVH in normal cell lines significantly, and antitumor activity of DVH was increased when it was loaded onto BSANPs without necrosis. These results suggest that DVH@BSANPs are a novel biocompatible sustained release system for effective therapeutic approach.
