Abstract
Purpose: This study aims to prepare Loratadine-loaded chitosan/tannic acid nanoparticles (LOR-CS/TAN NPs) through ionic gelation to be used as an anti-proliferative agent to aid in overcoming breast cancer propagation.
Methods: First, in-silico virtual screening was carried out to select the most appropriate anti-histaminic drug based on its inhibitory effect on the H1-histamine receptor, resulting in the selection of Loratadine (LOR). Molecular interaction between LOR with chitosan (CS), a positively charged polymer, and hyaluronan, a negatively charged polymer, was investigated separately through molecular docking, leading to the selection of CS. Optimization was carried out using Box Behnken Design, with concentrations of CS, LOR, and tannic acid (TAN) as independent variables. The optimized nanoparticles were then examined through morphological and physicochemical studies. Cell studies against the MCF-7 breast cancer cell line were conducted to assess cytotoxicity, cell cycle, apoptosis, and necrosis.
Results: The optimum formulation was determined to be CS (0.2% w/v), LOR (1:2 weight ratio to CS), and TAN (1:30.6 weight ratio to CS). The optimized LOR-CS/TAN NPs exhibited a size of 283 nm, a polydispersity index (PDI) of 0.102, and an entrapment efficiency of 78%, along with sustained drug release for 24 hours. The results demonstrated that LOR-CS/TAN NPs possess higher anti-cancer activity compared to free LOR. This enhanced activity is attributed to the synergistic effect of the drug and the designed nanoparticle, particularly due to the presence of tannic acid.
Conclusion: In conclusion, Loratadine-loaded chitosan/tannic acid nanoparticles (LOR-CS/TAN NPs) demonstrated enhanced anti-cancer activity against the MCF-7 breast cancer cell line. The synergistic effect of Loratadine and the nanoparticle system, particularly due to the presence of tannic acid, resulted in higher cytotoxicity compared to free Loratadine. These findings suggest that LOR-CS/TAN NPs have significant potential as a novel anti-proliferative agent for breast cancer therapy.
期刊介绍：
The International Journal of Nanomedicine is a globally recognized journal that focuses on the applications of nanotechnology in the biomedical field. It is a peer-reviewed and open-access publication that covers diverse aspects of this rapidly evolving research area.
With its strong emphasis on the clinical potential of nanoparticles in disease diagnostics, prevention, and treatment, the journal aims to showcase cutting-edge research and development in the field.
Starting from now, the International Journal of Nanomedicine will not accept meta-analyses for publication.
