Bakuchiol (BAK), [(1E,3S)-3-ethenyl-3,7-dimethyl-1,6-octadien-1-yl]
phenol is a prenylated phenolic
monoterpene extracted from the fruit of Psoralea corylifolia L., which belongs to the Leguminosae plant family. Previous research has shown that BAK exerts a variety of pharmacological effects, including
antioxidant, antibacterial, anti-inflammatory, antiaging and
estrogen-like effects. In addition, recent studies have indicated that BAK exerts protective effects in the heart, liver, skin and other organs. BAK treatment protects the heart against
ischemia-reperfusion injury through modulating cardioprotective pathways. BAK also inhibits
liver fibrosis via promoting myofibroblast apoptosis and relieves the hepatotoxicity of multiple toxicants by suppressing oxidative stress and inflammatory changes. BAK inhibits the proliferation of various
cancer cells, including stomach, breast and
skin cancer cells, thereby exerting anticancer effects. Further, BAK effectively slows skin aging by preserving skin
collagen. BAK treatment can protect against bone loss and delay
osteoporosis by exerting
estrogen-like effects. In addition, BAK remarkably reduces
blood glucose and
triglycerides and might be a potential pharmacological agent that can be used to protect against pancreatic beta-cell damage and diabetes progression. In this review, the pharmacological mechanisms and protective effects of BAK in human diseases are discussed, with a focus on the protective effects of BAK in the heart, liver and other important organs.
