ABSTRACT
Functional polymer-lipid hybrid nanoparticles (H-NPs) are a promising class of nanocarriers that combine the benefits of polymer and lipid nanoparticles, offering biocompatibility, structural stability, high loading capacity, and, most importantly, superior surface functionalization. Here, we report the synthesis and design of highly functional H-NPs with specificity toward the transferrin receptor (TfR), using a small molecule ligand, gambogic acid (GA). A fluorescence study revealed the molecular orientation of H-NPs, where the lipid-dense core is surrounded by a polymer exterior, functionalized with GA. Urolithin A, an immunomodulator and anti-inflammatory agent, served as a model drug-like compound to prepare H-NPs via traditional emulsion-based techniques, where H-NPs led to smaller particles (132 nm) and superior entrapment efficiencies (70 % at 10 % drug loading) compared to GA-conjugated polymeric nanoparticles (P-NPs) (157 nm and 52 % entrapment efficiency) and solid lipid nanoparticles (L-NPs) (186 nm and 29 % entrapment efficiency). H-NPs showed superior intracellular accumulation compared to individual NPs using human small intestinal epithelial (FHs 74) cells. The in vitro efficacy was demonstrated by flow cytometry analysis, in which UA-laden H-NPs showed excellent anti-inflammatory properties in cisplatin-induced injury in healthy human proximal tubular cell (HK2) model by decreasing the TLR4, NF-κß, and IL-ß expression. This preliminary work highlights the potential of H-NPs as a novel functional polymer-lipid drug delivery system, establishing the foundation for future research on its therapeutic potential in addressing chemotherapy-induced acute kidney injury in cancer patients.
