Abstract
Aim: In this study, a novel D-α-tocopheryl polyethylene glycol succinate (TPGS) modified bovine serum albumin (BSA) nanoparticles (NPs) were developed for delivery of Anastrozole (ANZ) which is optimized by Box-Behnken design (BBD). Fabricated TPGS-ANZ-BSA NPs were evaluated for their physicochemical and drug release characteristics.
Methods: TPGS-ANZ-BSA NPs were prepared by desolvation thermal gelation method and the effects of critical process parameter (CPP) which are BSA amount, TPGS concentration and stirring speed on the critical quality attributes (CQA) such as % drug loading (%DL) and particle size were studied using BBD. TPGS-ANZ-BSA NPs were characterized using different spectroscopic techniques including UV-Visible and FTIR is used to confirm the entrapment of ANZ in BSA. DSC and PXRD revealed the amorphization of ANZ in the TPGS-ANZ-BSA NPs after freeze drying. Scanning electron microscopy (SEM) analysis was performed for the surface morphology analyses NPs. In vitro release studies were performed at pH 5.5 and pH 7.4 for 48h to mimic tumour microenvironment.
Results: The BBD optimized TPGS-ANZ-BSA NPs showed 107 nm particle size with %DL 8.5± 0.5%. The spectroscopic and thermal characterizations revealed the successful encapsulation of ANZ inside the NPs. The TPGS-ANZ-BSA NPs were found to exhibit burst release at pH 5.5 and sustained release at pH 7.4. The short-term stability displayed no significant changes in physical properties TPGS-ANZ-BSA NPs at room temperature for a period one month.
Conclusion: The BBD optimized TPGS-ANZ-BSA nanoparticles showed enhanced physiochemical properties for ANZ and potential candidates for anticancer agent drugs delivery.

Emerging Nanotherapeutics for Mitigation of Neurodegenerative Disorders
Conditions affecting the central nervous system (CNS) present a significant hurdle due to limited access of both treatments and diagnostic tools for the brain. The blood-brain barrier (BBB) acts as a barrier, restricting the passage of molecules from the bloodstream into the brain. The most formidable challenge facing scientists is ...read more
Nanotechnology Based Chemotherapy for the treatment of Head & Neck Cancer
The escalating recurrence rates observed in Head and Neck cancer, particularly within the chemo-therapeutically treated cohort (50-60%), can be attributed to the non-selective nature of current anticancer drug delivery modalities. In this context, nanotechnology-based drug delivery systems emerge as a promising avenue for achieving precise localization of therapeutic agents to ...read more
