491-80-5 Usage

Description

Biochanin A is a natural isoflavone with diverse biological actions, most notably as a phytoestrogen. It can affect hormone levels by inhibiting 5α-reductase and 17β-hydroxysteroid dehydrogenase or altering aromatase (CYP19A1) activity. Also known as 4’-methyl genistein, biochanin A can be metabolized in vivo to genistein , another phytoestrogen with diverse effects. Biochanin A also intersects with signaling through peroxisome proliferator-activated receptors (PPARs), as it activates PPARγ (EC50 = 19 μM) and has also been shown to activate a PPARα promoter. Moreover, it increases the expression of the PPARγ coactivator PGC-1α, promoting mitochondrial biogenesis. Biochanin A also inhibits fatty acid amide hydrolase (IC50 = 2.4 μM) and acts as an agonist of the aryl hydrocarbon receptor (EC50 = 0.25 μM).

Uses

Different sources of media describe the Uses of 491-80-5 differently. You can refer to the following data:
1. It has putative benefits in dietary cancer prophylaxis. It has also been found to inhibit fatty acid amide hydrolase and to act as agonist of PPARgamma, nuclear receptor that is current pharmacological target for the treatment of diabetes type 2. It acts as an antineoplastic agent. It is a selective agonist at ER-β estrogen receptors, and may have chemopreventive efficacy against breast cancer. In line with its low activity at ER-α estrogen receptors, it is essentially devoid of uterotrophic activity. Biochanin A is also a ligand for the aryl hydrocarbon receptor (AhR). It reduces arterial resistance and enhances microcirculation perhaps via effects on potassium and/or calcium ion channels. Induction of sulfotransferases for xenobiotic detoxification has been proposed as a mechanism of its cancer preventive effects. It is a nitric oxide synthase inhibitor and apoptosis inducer
2. An isoflavone with anticancer proliferation, differentiation and chemopreventitive properties. Inhibits metabolic activation of benzo[a]pyrene

General Description

Biochanin A (BCA) is synthesized in vitro from phloroglucinol. A series of steps involving Friedel?Crafts reaction results in an intermediate product 1-(2,4,6-trihydroxyphenyl)-2-(4 methoxyphenyl) ethanone, which post cyclization leads to BCA. It is catabolized to isoflavone genistein post ingestion.

Biochem/physiol Actions

Biochanin A is an isoflavone phytoestrogen found in red clover (Trifolium pratense) that is a selective agonist at ER-β estrogen receptors, and may have chemopreventive efficacy against breast cancer. In line with its low activity at ER-α estrogen receptors, it is essentially devoid of uterotrophic activity. Biochanin A is also a ligand for the aryl hydrocarbon receptor (AhR). It reduces arterial resistance and enhances microcirculation perhaps via effects on potassium and/or calcium ion channels. Induction of sulfotransferases for xenobiotic detoxification has been proposed as a mechanism of its cancer preventive effects.

Check Digit Verification of cas no

The CAS Registry Mumber 491-80-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,9 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 491-80:
(5*4)+(4*9)+(3*1)+(2*8)+(1*0)=75
75 % 10 = 5
So 491-80-5 is a valid CAS Registry Number.

Isoflavonoid glycosides from Dalbergia sissoo

Identification of ortho catechol-containing isoflavone as a privileged scaffold that directly prevents the aggregation of both amyloid β plaques and tau-mediated neurofibrillary tangles and its in vivo evaluation

In this study, polyhydroxyisoflavones that directly prevent the aggregation of both amyloid β (Aβ) and tau were expediently synthesized via divergent Pd(0)-catalyzed Suzuki-Miyaura coupling and then biologically evaluated. By preliminary structure–activity relationship studies using thioflavin T (ThT) assays, an ortho-catechol containing isoflavone scaffold was proven to be crucial for preventing both Aβ aggregation and tau-mediated neurofibrillary tangle formation. Additional TEM experiment confirmed that ortho-catechol containing isoflavone 4d significantly prevented the aggregation of both Aβ and tau. To investigate the mode of action (MOA) of 4d, which possesses an ortho-catechol moiety, 1H-15N HSQC NMR analysis was thoroughly performed and the result indicated that 4d could directly inhibit both the formation of Aβ42 fibrils and the formation of tau-derived neurofibrils, probably through the catechol-mediated nucleation of tau. Finally, 4d was demonstrated to alleviate cognitive impairment and pathologies related to Alzheimer's disease in a 5XFAD transgenic mouse model.

-

, (2019/10/02)

The invention relates to a cytosine N-isoflavone compound as well as a preparation method and application thereof. The compound has a structural formula as shown in the specification, wherein R1 is selected from one of hydroxyl, alkoxy, amido or halo, R2 is selected from one of hydrogen, alkyl or aryl, and R3 is selected from one or a combination of several of hydroxyl, alkoxy, amido or halo. Compared with the prior art, the cytosine N-isoflavone compound has the characteristic that an isoflavone compound serving as a structural unit is spliced to N on the 12th position of cytosine by using acombined synthesis technology, so that a series of cytosine-isoflavone derivatives are synthesized, and a novel active pharmacological action is exerted.
