Development of an Innovative Nanosystem Based on Functionalized Albumin and Oxidized Gellan for the Synergistic Delivery of Curcumin and Temozolomide in the Treatment of Brain Cancer.

ABSTRACT: Treating brain cancer remains challenging due to the blood-brain barrier (BBB) and the systemic toxicity of chemotherapy. This study focuses on developing human serum albumin (HSA) nanoparticles modified with low-molecular-weight protamine (LMWP) to improve crossing the BBB and enable targeted delivery of curcumin and temozolomide (TMZ). Nanoparticle stability was enhanced by crosslinking with aldehyde groups from oxidized gellan (OG). The successful attachment of LMWP to HSA at the thiol group of Cys34 was confirmed through FT-IR and ¹H-NMR analyses. Most self-assembled nanoparticles were smaller than 200 nm in diameter. Curcumin showed higher encapsulation efficiency than TMZ. In vitro drug release was pH-dependent: curcumin released more at pH 7.4, while TMZ release was bette
