In vitro, it potently displaces benzodiazepine binding to rat brain membranes with nM affinity2, and inhibits binding at other GPCRs3.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlternative names:\u003c\/strong\u003e 3',8''-Biapigenin, Didemethyl-ginkgetin\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eScientific background\u003c\/h3\u003e \u003cp\u003eAmentoflavone is a natural compound derived from the plant Selaginella tamariscina. It is a negative allosteric modulator of GABA(A) receptors. Amentoflavone can be found in a number of plants with medicinal properties including Ginkgo biloba and Hypercium perforatum. Amentoflavone is the first high affinity ligand known for the benzodiazepine receptor devoid of nitrogen in its structure. It has been hypothesized recently that amentoflavone can cross the blood brain barrier in vivo by passive diffusion. In addition to its effect on GABA receptors, amentoflavone inhibits binding at 5-HT, D3-dopamine and δ-opioid receptors. The action of amentoflavone on the GABA(A) receptor is independent of high affinity benzodiazepine modulatory sites on the receptor. Amentoflavone and other substances of the flavone class have been found to exert anxiolytic activity in mice without the side effect associated with the use of benzodiazepines1.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eLead time:\u003c\/strong\u003e 1-2 Business Days\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCountry of origin:\u003c\/strong\u003e Israel\/IL\u003c\/p\u003e \u003ch3\u003eApplications key\u003c\/h3\u003e \u003cp\u003eApplication key: FC- Flow cytometry, IFC- Indirect flow cytometry, IHC- Immunohistochemistry,LCI- Live cell imaging, Calcium imaging assay,Cell survival assay, Electrophysiology, Neurite outgrowth assay.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eBioassay tested:\u003c\/strong\u003e Yes\u003c\/p\u003e","brand":"Alomone Labs","offers":[{"title":"1 mg \/ 1","offer_id":53249707671917,"sku":"A-165-1MG-1","price":92.0,"currency_code":"USD","in_stock":true},{"title":"10 mg \/ 1","offer_id":53311546786157,"sku":"A-165-10MG-1","price":266.0,"currency_code":"USD","in_stock":true},{"title":"25 mg \/ 1","offer_id":53311546818925,"sku":"A-165-25MG-1","price":529.0,"currency_code":"USD","in_stock":true},{"title":"5 mg \/ 1","offer_id":53311546851693,"sku":"A-165-5MG-1","price":192.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/A-165_gr.gif?v=1778544406","url":"https:\/\/www.ebiohippo.com\/products\/amentoflavone-bhb21300003","provider":"BioHippo","version":"1.0","type":"link"}
