Description:

beta-Asarone has neuroprotection, anti-tumor, anthelmintic, anti-inflammary, and anticoagulant effects, it can afford a beneficial inhibition on both mRNA and protein expression of Bad, Bax, and cleavage of caspases 9 in rat hippocampus following intrahippocampal injections of Abeta (1-42).beta-Asarone prevents autophagy and synaptic loss by reducing ROCK expression in SAMP8 mice. beta Asarone can cause liver and cardiac damages, it also has reproductive toxicity.

Compositional variations and anthelmentic activity of essential oils from rhizomes of different wild populations of Acorus calamus L. and its major component, beta-Asarone.   

Hydro-distilled essential oils from Acorus calamus rhizomes collected from six different geographical zones in the northwest Himalayan region of Uttarakhand have been analyzed by GC and GC/MS. 

METHODS AND RESULTS:

All the oils differed in their qualitative and quantitative make up, although beta-Asarone was the major constituent of all of them. The essential oils and the isolated beta-Asarone were screened for anthelmintic activity using contractility of Ascaridia galli. beta-Asarone, in particular, showed potent activity with IC50 values of 75.4 +/- 61.8 ng/mL.

β-Asarone (cis-2,4,5-trimethoxy-1-allyl phenyl), attenuates pro-inflammatory mediators by inhibiting NF-κB signaling and the JNK pathway in LPS activated BV-2 microglia cells.   

Acorus species contains diverse pharmacologically active phytochemicals including α-asarone, beta-Asarone, and eugenol. 

METHODS AND RESULTS:

We determined if beta-Asarone isolated from Acorus gramineus (AG) Solander would be efficacious in protecting BV-2 microglia cells from lipopolysaccharide (LPS)-induced stress signaling. BV-2 microglial cells were pretreated with an AG ethanol extract (1, 10, and 100 μg/mL) or beta-Asarone (10, 50, and 100 μM) prior to exposure to LPS (100 ng/mL). AG and beta-Asarone inhibited LPS-induced production of nitric oxide in a dose-dependent manner. The mRNA and protein levels of inducible nitric oxide synthase and cyclooxygenase-2 also decreased dose dependently following AG and beta-Asarone treatments. Immunostaining and immunoblot studies revealed that beta-Asarone also suppressed nuclear factor (NF)-κB activation by blocking IkB degradation. Further mechanistic studies revealed that beta-Asarone acted through the JNK/MAPK pathway. 

CONCLUSIONS:

Taken together, our findings demonstrate that beta-Asarone exhibits anti-inflammatory effects by suppressing the production of pro-inflammatory mediators through NF-κB signaling and the JNK pathways in activated microglial cells and might be developed as a promising candidate to treat various neuroinflammatory diseases.

β-Asarone induces senescence in colorectal cancer cells by inducing lamin B1 expression.    

Colorectal cancer is a leading cause of cancer mortality with a complex carcinogenesis that includes reduced cellular senescence. Lamin proteins are decreased in senescing cells, and frequently decreased in malignancies. 

METHODS AND RESULTS:

This study identified a new drug candidate for colorectal cancer that appears to target cell senescence via a lamin protein. beta-Asarone (1-propenyl-2,4,5-methoxybenzol) is a compound from the traditional medical herb Acorus calamus Linn. This study tested the in vitro and in vivo effects of beta-Asarone on colorectal cancer cells by testing cell viability using human colorectal cell lines HT29 and SW480 in MTT assays; tumorigenesis using xenografts in nude mice and a mouse model of colorectal cancer; cell senescence using senescence-associated β-galactosidase activity; and expression of cancer and senescence-related proteins, specifically lamins, Oct-1, p53, p21, and p15, by Western blot. beta-Asarone appeared to increase expression of lamin B1, p53, p21, but not lamin A/C. beta-Asarone regulates p15 expression by regulation of Oct-1 binding. 

CONCLUSIONS:

Collectively, the results suggested that beta-Asarone inhibits colon cancer formation in vivo and in vitro by inducing senescence. Since beta-Asarone induced lamin B1 expression, a model is proposed in which beta-Asarone inhibits colorectal cancer by inducing senescence through lamin B1.
