Corylin is a phenolic compound isolated from the Psoralea corylifolia L, with anti-inflammatory and immunosuppressive properties [1]. Corylin activates BAT and Beige adipocytes through SIRT1 and β3-AR regulation, exerting anti-obesity effect[2]. Corylin has been widely used to prolong the life span of aged mice under metabolic stress, improve physiological function, reduce metabolic stress and maintain tissue function[3].
In vitro, Corylin treatment for 24 hours significantly inhibited the proliferation of MCF-7 cells and MDA-MB-231 cells with IC50 values of 10.58µM and 13.59µM, respectively[4]. Treatment of RAW264.7 cells with 10µM Corylin for 24h inhibited cell viability and migration[5]. Pretreatment of BV2 cells with 10µM Corylin for 1 hour attenuated lipopolysaccharide (LPS) -induced inflammatory response, reduced TNF-α and IL-6 production, and inhibited MAPK phosphorylation[6].
In vivo, Corylin treatment via oral administration at a dose of 50mg/kg/day for 15 weeks reduced oxidative stress, VCAM-1 and NOX4 Expression, and atherosclerotic plaques in the thoracic aorta of cholesterol diet-treated mice[7]. Intraperitoneal injection of a single dose of Corylin (20mg/kg) for 12 hours significantly alleviated LPS-induced cardiac dysfunction and reduced inflammation in mice[8].
