Wound healing represents a significant challenge within the field of medical science. Contemporary clinical practices increasingly favor the utilization of herbal compounds to facilitate the repair process. Among these compounds, coumarin-a phytochemical noted for its antibacterial and wound-healing properties-has garnered considerable attention. This study investigates the potential advantages of incorporating coumarin into wound dressings within an experimental model. Our synthesized target compound 3-(3-(4-hydroxy-2-oxo-2 H -chromen-3-yl)-5-(pyridin-3-yl)-1 H -pyrazol-1-yl) indolin-2-one ( CPPI ) demonstrated notable antimicrobial activity against the pathogenic Staphylococcus aureus MRSA, Bacillus cereus , and Pseudomonas aeruginosa . Moreover, both in vitro and in vivo experiments showed that CPPI significantly enhanced the migration of skin fibroblast cells and promoted the wound healing process. Furthermore, it facilitated complete re-epithelialization of the wounds. Histological analysis revealed the formation of well-structured granulation tissue and a reduction in indicators of wound infection, evidenced by a minimal presence of inflammatory cells in comparison to untreated wounds. Additionally, in silico molecular docking studies of CPPI indicated significant binding affinity within COX-2 active site along with a stable complex during molecular dynamics simulations. Collectively, the findings of this study suggest that CPPI can provide a protective effect against infections in cutaneous wounds, attributable to its antimicrobial properties.
