“…Phloroglucinol derivatives in aspirin BB induced reactive oxygen species to exert their antibacterial activity against S. aureus in vitro [ 27 ]. Nevertheless, most reports emphasized the synthesis of phloroglucinol, and do not delve into the antimicrobial mechanisms delve into the antimicrobial mechanism [ 15 , 28 , 29 ]. How to promote infected wound healing, improve re-epithelialization and reduce bacterial infection is paramount.…”

“…Therefore, preventing the growth of pathogenic bacteria in the wounds helps to promote wound healing. In some studies, phloroglucinol was found to exhibit anticancer [ 13 ], anti-inflammatory [ 14 ], and antibacterial activities [ 15 ]. Due to their potential antibacterial activity, some phloroglucinol has been synthesized, and its structure–activity relationships and mechanisms of action have also been studied further [ 16 ].…”

Globally, wound infection is considered to be one of the major healthcare problems, with bacterial infections being the most critical threat, leading to poor and delayed wound healing, and even death. As a superbug, methicillin-resistant Staphylococcus aureus (MRSA) causes a profound hazard to public health safety, prompting us to search for alternative treatment approaches. Herein, the MTT test and Hoechst/propidium iodide (PI) staining demonstrated that PD was slightly less toxic to human fibroblasts including Human keratinocytes (HaCaT) cell line than Silver sulfadiazine (SSD), and Vancomycin (Van). In the MRSA-infected wound model, PD hydrogel (1%, 2.5%) was applied with for 14 days. The wound healing of PD hydrogel groups was superior to the SSD, Van, and control groups. Remarkably, the experimental results showed that PD reduced the number of skin bacteria, reduced inflammation, and upregulated the expression of PCNA (keratinocyte proliferation marker) and CD31 (angiogenesis manufacturer) at the wound site by histology (including hematoxylin–eosin (HE) staining, Masson staining) and immunohistochemistry. Additionally, no toxicity, hemocompatibility or histopathological changes to organs were observed. Altogether, these results suggested the potential of PD hydrogel as a safe, effective, and low toxicity hydrogel for the future clinical treatment of MRSA-infected wounds.
