p-Synephrine is widely used in weight loss and weight management as well as in sports performance products, which has antidepressant-like effects in the murine models of forced swimming and tail suspension, it also exerts potent anti-inflammatory effects by inhibition of the NF-κB signaling pathway. Synephrine inhibits eotaxin-1 expression via the STAT6 signaling pathway. Synephrine is a phenethylamine alkaloid that is 4-(2-aminoethyl)phenol substituted by a hydroxy group at position 1 and a methyl group at the amino nitrogen. It has a role as an alpha-adrenergic agonist and a plant metabolite. It is a member of ethanolamines, a member of phenols and a phenethylamine alkaloid. It is a conjugate base of a synephrinium.
