Abstract

Objectives: Triple-negative breast Cancer (TNBC) is an aggressive subtype of breast Cancer with limited treatment options. Cannabidiol (CBD) has demonstrated Anticancer potential, but its clinical application is hindered by poor solubility and nonspecific distribution. This study aimed to develop a folic acid-modified chitosan (FA-CS) nanoparticle system to enhance the targeted delivery and therapeutic efficacy of CBD against TNBC.

Methods: FA-CS@CBD nanoparticles were synthesized and characterized for morphology, size distribution, zeta potential, and stability. Their in vitro Anticancer effects were evaluated through cytotoxicity, cellular uptake, Apoptosis, and Reactive Oxygen Species (ROS) assays in 4T1 breast Cancer cells. The in vivo antitumour efficacy and systemic toxicity were assessed using a TNBC mouse model.

Key findings: FA-CS@CBD nanoparticles exhibited uniform morphology, stable physicochemical properties, and efficient cellular uptake. Compared to free CBD, the nanoparticles significantly enhanced ROS production, induced Apoptosis, and inhibited migration in 4T1 cells. In vivo studies demonstrated strong tumour-targeting capability and a tumour inhibition rate of 68.07%, with minimal systemic toxicity.

Conclusions: The FA-CS@CBD nanoparticle system improved the targeted delivery and therapeutic effects of CBD against TNBC while maintaining favorable biocompatibility. These findings highlight the potential of FA-CS-based nanocarriers for enhancing CBD clinical application in breast Cancer therapy.
