Abstract

In this study, a simple approach was used for the synthesis of a water-soluble hyaluronic acid-quercetin (HA-Q) pendant drug conjugate to evaluate its potential wound-healing properties. The HA-Q conjugation was confirmed by Fourier-transform infrared spectroscopy (FTIR), ultraviolet-visible spectrophotometry (UV-Vis), and nuclear magnetic resonance (NMR) spectroscopy techniques. To produce the HA-Q, quercetin was conjugated on the HA backbone to the extent of 44.7 %. The HA-Q conjugate was soluble in water and a solution with a concentration of 20 mg/ml was prepared. The conjugate exhibited good biocompatibility and supported the growth and cell migration of skin fibroblast cells. HA-Q presented improved radical scavenging capacity compared to quercetin (Q) alone. The overall results confirmed the potential role of HA-Q in wound healing applications.
