Methotrexate MTX as a chemotherapeutic agent has the potential to be used in the treatment of brain tumors, but it is less used due to insufficient penetration into the brain parenchyma. By designing nanotechnology-based systems, it can be possible to overcome these limitations. In this study, the sonication method was used to prepare MTX loaded human serum albumin HSA nanoparticles. The results indicated that MTX loaded HSA nanoparticles have the size less than 100 nm. The obtained values for drug loading and encapsulation efficacy were 3 and 47, respectively; and the results of thermal analysis of nanoparticles demonstated the amorphous form of MTX in HSA. In the release profile, slow and controlled release of nanoparticles was also observed in the neutral environment. In addition, the results indicated the decreased cytotoxic effects of MTX loaded HSA nanoparticles in comparison with free MTX. Therefore, the proposed formulation can have high potential in drug delivery systems to glioblastoma cells.
