Mannosylated preactivated hyaluronic acid-based nanostructures for bacterial infection treatment
Abstract
Salmonella Typhi is an intracellular bacterium causing a variety of enteric diseases, being typhoid fever the most common. Current modalities for treating S. typhi infection are subjected to multi-drug resistance. Herein, a novel macrophage targeting approach was developed via coating bioinspired mannosylated preactivated hyaluronic acid (Man-PTHA) ligands on a self-nanoemulsifying drug delivery system (SNEDDS) loaded with the antibacterial drug ciprofloxacin (CIP). The shake flask method was used to determine the drug solubility in the different excipients (oil, surfactants and co-surfactants). Man-PTHA were characterized by physicochemical, in vitro, and in vivo parameters. The mean droplet size was 257 nm, with a PDI of 0.37 and zeta potential of − 15 mV. In 72 h, 85 % of the drug was released in a sustained manner, and the entrapment efficiency was 95 %. Outstanding biocompatibility, mucoadhesion, muco-penetration, anti-bacterial action and hemocompatibility were observed. Intra-macrophage survival of S. typhi was minimal (1 %) with maximum nanoparticle uptake, as shown by their higher fluorescence intensity. Serum biochemistry evaluation showed no significant changes or toxicity, and histopathological evaluation confirmed the entero-protective nature of the bioinspired polymers. Overall, results confirm that Man-PTHA SNEDDS can be employed as novel and effective delivery systems for the therapeutic management of S. typhi infection.
