Isoliquiritigenin (ISL), a flavonoid compound derived from licorice roots known as chalcone, has demonstrated multifaceted pharmacological potential. However, its effects on diabetic wounds and the detailed mechanisms remain to be investigated. Through in-depth exploration using network pharmacology, we successfully predicted potential therapeutic targets of ISL for ischemic diseases.

Subsequent in vivo experiments demonstrated that ISL significantly enhanced the efferocytosis of dendritic cells (DC), improving the functional behaviors of endothelial cells. Further research indicated that ISL promoted DC efferocytosis by regulating SLC7A11-mediated glycolysis. Notably, the overexpression of SLC7A11 diminished the positive effects of ISL, suggesting a potential antagonistic role of SLC7A11 in the regulatory process. In the wounds of diabetic mice, we observed that ISL accelerated DC efferocytosis and angiogenesis, resulting in faster wound closure and better tissue repair.
