Antidepressant-like effects of p-synephrine in mouse models of immobility tests

Neuroscience Letters, 1996
We studied the effects of p-synephrine on the immobility behaviors and on the spontaneous motor activity in mice. p-Synephrine at oral doses from 1 to 10 mg/kg significantly decreased the duration of immobility in the tail suspension test and the forced swimming test in mice.

Induction of beige adipocytes by naturally occurring β3-adrenoceptor agonist p-synephrine

European Journal of Pharmacology, 2018
The prevalence of obesity and its associated diseases is increasing worldwide, and the therapeutic potential of increasing energy expenditure through differentiation or activation of beige adipocytes has attracted much interest. Therefore, we explored naturally occurring compounds that induce beige adipocytes by screening for activity to induce mRNA ...

Gas Chromatographic Method for Analysis of p-Synephrine in Citrus aurantium L. Products

Chromatographia, 2009
A method has been developed and validated for the identification and quantification of p-synephrine in Citrus aurantium L. products. The approach comprises GC-FID analysis followed by GC-MS confirmation after clean-up by solid phase extraction with a strong cation-exchange phase and derivatization with cyclohexanone.

p-Synephrine suppresses lipopolysaccharide-induced acute lung injury by inhibition of the NF-κB signaling pathway

Inflammation Research, 2014
We investigated whether p-synephrine exerts potent anti-inflammatory effects against acute lung injury (ALI) induced by lipopolysaccharide (LPS) in vivo, and we further investigated the inhibitory mechanism of p-synephrine in LPS-induced ALI.Lipopolysaccharide (0.5 mg/kg) was instilled intranasally in phosphate-buffered saline to induce acute lung ...
