Magnolol is a traditional Chinese medicine from the root and bark of Magnolia officinalis. It has long been used to treat anxiety, cough, headache and allergies, as well as a variety of inflammations. Lung inflammation is a key event in the pathogenesis of asthma and chronic obstructive pulmonary

We studied the effect of aqueous extract of Magnolia officinalis bark (Magnoliaceae) (MOAE) on the immediate hypersensitivity reaction. MOAE (0.01 to 1 g/kg) dose-dependently inhibited compound 48/80 induced systemic anaphylaxis in rats. MOAE (0.1 and 1 g/kg) also significantly inhibited local

Nitric oxide (NO) and tumor necrosis factor-alpha (TNF-alpha) are the major mediators produced in activated macrophages which contribute to the circulatory failure associated with septic shock. An activity-guided fractionation of an MeOH extract of stem bark of Magnolia obovata afforded two

In the present study, syringin, isolated by activity-guided fractionation of the ethyl acetate (EtOAc) extracts of the stem bark of Magnolia sieboldii, and sinapyl alcohol, the hydrolysate of syringin, were evaluated for anti-inflammatory and antinociceptive activities. Sinapyl alcohol (20, 30

The generally accepted hypothesis for the pathogenesis of alcoholic liver disease (ALD) is the two-hit model, which proposes that fat accumulation in the liver increases the sensitivity of the liver to a second hit that leads to inflammatory liver cell damage. In this study we evaluated the effects

The protective effect of magnolol, a component of Magnolia officinalis, against hypoxia-induced cell injury in cortical neuron-astrocyte mixed cultures was examined. Exposure of the cells to chemical hypoxia (0.5 mM KCN) produced morphological changes in neurons but not in astrocytes. KCN induced

Honokiol, a small-molecule polyphenol derived and isolated from the Chinese medicinal herb Magnolia officinalis, has been shown to possess a wide range of pharmacological activities. In the present study, we aimed to investigate the effects of honokiol on tumor necrosis factor-α (TNF-α)-induced

Magnolol is a compound extracted from the Chinese medicinal herb Magnolia officinalis. It has multiple pharmacological effects, notably as an anti-oxidant. The aim of this study was to evaluate the effects of magnolol on sepsis induced by intravenous (i.v.) administration of lipopolysaccharide (LPS;

Acute liver failure (ALF), an often fatal condition characterized by massive hepatocyte necrosis, is frequently caused by drug poisoning, particularly with acetaminophen (N-acetyl-p-aminophenol/APAP). Hepatocyte necrosis is consecutive to glutathione (GSH) depletion and mitochondrial damage caused

Osteoarthritis (OA), defined as a long-term progressive joint disease, is characterized by cartilage impairment and erosion. In recent decades, magnolol, as a type of lignin extracted from Magnolia officinalis, has been proved to play a potent anti-inflammatory role in various diseases. The

BACKGROUND Since the increasing smoking rate among women has resulted in higher rates of embryonic malformations, it is important to search for an efficient and inexpensive agent that can help reduce the rate of serious fetal anomalies caused by maternal cigarette smoking. In this study, the

Temozolomide (TMZ)-induced chemoresistance to human glioblastomas is a critical challenge now. Our previous studies showed that honokiol, a major bioactive constituent of Magnolia officinalis (Houpo), can kill human glioblastoma cells and suppresses glioblastoma growth. This study was further

Magnolol, a constituent of the bark of Magnolia officinalis, has been reported to decrease myocardial stunning and infarct size. In this study, we investigated whether magnolol can reduce renal ischemia and reperfusion (I/R) injury. Renal I/R, induced by a 60-min occlusion of bilateral renal

The present study reports the antiinflammatory activity of a methanol extract isolated from the stem bark of Magnolia kobus (MK). MK potently inhibited lipopolysaccharide (LPS)-induced production of nitric oxide and interleukin-1beta (IL-1beta) in RAW 264.7 cells, a murine macrophage-like cell line.

Aristolochic acids (AA) are nephrotoxic agents found in Aristolochia species whose consumption leads to the onset of a progressive tubulointerstitial fibrosis. This AA-nephropathy was first reported during the Belgian outbreak of the 1990's in which more than a hundred patients consumed slimming
