The β-asarone was a major component of Acorus tatarinowii Schott which had significant pharmacological effects on the central nervous system (CNS). We have reported that β-asarone can pass through the blood-brain barrier (BBB) and then go into the brain tissues in the 2002. However, the β-asarone in the brain blood was not excluded, which might lead to a false positive result. In this study, we...

Abstract Background Metabolic dysregulation is one of the hallmarks tumor cell proliferation. Evidence indicates potential role 5′adenosine monophosphate-activated protein kinase (AMPK) and B/Akt signaling pathway in regulating proliferation, survival, apoptosis. The present study explores effect metformin HCl combination α- β-asarone on proliferation HepG2 cells presence high glucose levels si...

α and β asarones are natural constituents of some aromatic plants, especially species of the genus Acorus (Araceae). In addition to reports of beneficial properties of asarones, genotoxicity and carcinogenicity are also reported. Due to potential toxic effects of β-asarone, a limit of exposure from herbal products of ~2 μg/kg body weight/day has been set temporarily until a full benefit/risk as...

In this study, we investigated the influence of β-asarone, the major ingredient of Acorus tatarinowii Schott, on depressive-like behavior induced by the chronic unpredictable mild stresses (CUMS) paradigm and to clarify the underlying mechanisms. The results show that β-asarone treatment partially reversed the CUMS-induced depression-like behaviors in both the forced swim and sucrose preference...

β-asarone, the main component in the volatile oil of Acori tatarinowii Rhizoma, has been found to possess antitumor activity. However, its effect and mechanisms against tumor invasion and epithelial-mesenchymal transition (EMT) are still unclear. In this study, no or less cytotoxicity was caused by β-asarone within 0-120 μM in human glioma U251 cells for 48 h. β-asarone (30 and 60 μM) inhibited...

The cytotoxicity of alpha- and beta-asarone was investigated with the BrdU assay in HepG2-cells. Alpha-asarone was found to be more toxic than beta-asarone after 24 hours of treatment. Investigation of the genotoxicity using the micronucleus assay in the HepG2-cell system showed that only after metabolic activation by a liver microsomal preparation, beta-asarone was able to induce micronuclei a...

AIM β-asarone, an active component of Acori graminei rhizome, has been reported to have neuroprotective effects in Alzheimer's disease. As the underlying mechanism is not known, we investigated the neuroprotective effects of β-asarone in an APP/PS1 double transgenic mouse model and in NG108 cells. MATERIALS AND METHODS APPswe/PS1dE9 double transgenic male mice were randomly assigned to a mode...

The cellular accumulation of cholesterol is critical in the development and progression of atherosclerosis. ATP-binding cassette (ABC) transporters play an essential role in mediating the efflux of excess cholesterol. In the current study, we investigated whether purple Perilla frutescens extracts (PPE) at a non-toxic concentration of 1-10 µg/ml stimulate the induction of the ABC transporters, ...

For centuries, extracts of Acorus gramineus have been used extensively in traditional Chinese medicine for the treatment, management, and/or control of human ailments, including central nervous system disorders such as convulsions and epilepsy. In the present study, we investigated the anticonvulsant activity of chronic treatment with the plant's major essential oil component (a-asarone, 50-200...

BACKGROUND Ischemic hypoxic brain injury often causes irreversible brain damage. The lack of effective and widely applicable pharmacological treatments for ischemic stroke patients may explain a growing interest in traditional medicines. β-Asarone, which has significant pharmacological effects on the central nervous system (CNS), was used in the prevention of cerebral ischemia in this paper. ...
