Vulpinic acid is a lichen metabolite with diverse biological activities. It is active against C. perfringens, B. vulgatus, B. fragilis, B. loescheii, P. acnes, E. faecium, and methicillin-susceptible and -resistant S. aureus. Vulpinic acid prevents UVB-induced apoptosis, cytotoxicity, and cytoskeletal modifications in HaCaT human keratinocytes. It also increases scratch wound healing of HaCaT cells. Vulpinic acid reduces hydrogen peroxide-induced production of reactive oxygen species (ROS) and cytotoxicity in human umbilical vein endothelial cells (HUVECs).
