Naringin is a flavonoid that exists in many plants and traditional Chinese medicines. In this study, a highly sensitive and specific electrospray ionization (ESI) liquid chromatography-tandem mass spectrometry (LC/MS/MS) method was developed for quantification of naringin and its two metabolites, naringenin and naringenin glucuronide. Naringin and(More)
Target identification of the known bioactive compounds and novel synthetic analogs is a very important research field in medicinal chemistry, biochemistry, and pharmacology. It is also a challenging and costly step towards chemical biology and phenotypic screening. In silico identification of potential biological targets for chemical compounds offers an(More)
There is a need of in vivo COPD models for mucus hypersecretion study. The current study compared three rat models induced by cigarette smoke (CS) exposure alone or combined with pre- or post-treatment with lipopolysaccharide (LPS). Forty rats were randomly divided into the four following groups: control group, LPS + CS group (CS exposure for 4-wk combined(More)
Naringin has been reported to act as an effective anti-inflammatory compound. In a previous study, we demonstrated that the anti-inflammatory effect of naringin on lipopolysaccharide (LPS)-induced acute lung injury in mice correlated with the inhibition of the nuclear factor-κB (NF-κB) pathway. However, the effects(More)
HYPOTHESIS Hepatocellular carcinoma (HCC) is one of the most malignant human tumors and one of the risk factors is its highly metastatic property. Coptidis Rhizoma aqueous extract (CRAE) is able to suppress the migration and invasion of HCC cells, MHCC97-L, and F-actin reorganization and Rho signaling inhibition is involved. MAIN METHODS CRAE was prepared(More)
Naringin has been reported as an effective anti-inflammatory compound. We previously showed that naringin had antitussive effect on experimentally induced cough in guinea pigs. However, the effects and mechanism of naringin on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice are not fully understood. In this study, our aim was to evaluate(More)
Naringin, a major active flavonone glycoside from a traditional Chinese medicine Huajuhong, has been demonstrated to have activities such as peripheral antitussive, mucoregulator and anti-inflammatory. The purpose of this study was to elucidate the metabolism and mass balance of orally administered naringin in rats and dogs. After oral administration of(More)
The mechanism of action of naringin has been investigated in different models of experimentally induced cough in guinea pigs. In contrast to codeine phosphate (6 mg/kg, intravenous administration [i. v.]), naringin (15, 30, and 60 mg/kg, i. v.) had no central antitussive effect on cough elicited by electrical stimulation of the superior laryngeal nerve.(More)
Naringenin, the aglycone of naringin, has been reported to attenuate MUC5AC secretion by inhibiting activity of nuclear factor kappa B (NF-κB) via EGFR-PI3K-Akt/ERK MAPKinase signaling pathways. However, previous studies demonstrated that the MUC5AC promoter was located in two different regions: an activator protein-1 (AP-1) binding site and a NF-κB binding(More)
