Embodiment 1

[0041] The preparation of embodiment 1 calycosin

[0042] Collect 500 g of feces from experimental rats administered with acteocoside by gavage, extract 3 times with 5 times the amount of methanol, combine the obtained methanol extracts, evaporate the methanol to dryness, and then adsorb through 101 macroporous resin. Then, 101 macroporous resins were first eluted with 30% ethanol, then 101 macroporous resins were eluted with 50% ethanol and fractions were collected, and finally 101 macroporous resins were regenerated with 90% ethanol. Afterwards, the obtained fractions were evaporated to dryness, adsorbed on Sephadex LH-20 dextran gel, and eluted with ethanol. After thin-layer chromatography, the eluents containing the same components were combined to obtain three parts of A, B and C. Fraction, the obtained fraction B is adsorbed on silica gel H60, after dichloromethane-methanol (100:1-5:1, volume ratio) eluent elution, and after enrichment by semi-preparative liquid chromato...

Embodiment 2

[0043] The preparation of embodiment 2 calycosin

[0044] Actascoisoflavone was treated with 1M H under acidic conditions 2 SO 4 After hydrolysis, the anion exchange resin Amberlite (OH - ) separation to obtain calycosin (m / z: 285 [M+H] + ; 13C-NMR (DMSO-d6, 100MHz) δ (ppm): 174.53 (C-4), 162.48 (C-7), 157.33 (C-9), 152.98 (C-2), 147.47 (C-4') , 146.00(C-3'), 127.24(C-5), 124.68(C-1'), 123.33(C-3), 119.65(C-6'), 116.62(C-10), 116.42(C- 2'), 111.95(C-5'), 102.05(C-8), 55.65(OMe))

Embodiment 3

[0045] Embodiment 3 antiviral activity test

[0046] 1. Culture medium and culture medium

[0047] Cell culture medium: containing 10% fetal bovine serum, product of Tianjin Haoyang Biological Products Technology Co., Ltd.; DMEM (high glucose) medium, RPMI-1640 and fetal bovine serum were purchased from Gibco, USA.

[0048] RPMI-1640 complete medium: containing 10% fetal bovine serum, 2 mM L-glutamine, 10 mM HEPES, 50 μM 2-mercaptoethanol (purchased from Bio-Rad), 100,000 IU penicillin and 100 μg / ml streptomycin.

[0049] 2. Cells and viruses

[0050] Human laryngeal carcinoma epithelial cells (Hep-2) were purchased from the Cell Center of the Institute of Basic Medicine, Peking Union Medical College, China. Coxsackie virus B type 3 (CoxB3) Nancy strain was routinely passaged by Cui Xiaolan's laboratory of the Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences, half of the tissue culture infectious dose (50% Tissue culture infectious dose, TCID 5...

Abstract

The invention provides applications of an isoflavone compound in preparing antiviral medicaments. The isoflavone compound provided by the invention is calycosin, and has obvious AIDS (Acquired Immune Deficiency Syndrome) virus and coxsakie virus resistant activities. The isoflavone compound provided by the invention as an active component is used for preparing medicaments for preventing or treating viral diseases.

Description

technical field [0001] The invention relates to the use of isoflavone compounds, in particular to the use of calycosin in the preparation of antiviral drugs. Background technique [0002] In recent years, clinical practice has proved that Astragalus has a significant effect in the treatment of viral myocarditis. But the active ingredients in it are not yet fully understood. A research team has conducted in-depth years of research on the relationship between the effective parts of Astragalus and its main active ingredients against Coxsackie virus and the treatment of viral myocarditis, and found that calycosin-7-O-β-D-glucopyranoside ( Hereinafter referred to as: actcocoside) has significant antiviral activity on cells and animal models infected by Coxsackie Virus B3 (CVB3) (Biol.Pharm.Bull.2009, 68-73; CN1813711B). Both in vivo and in vitro experiments showed that verbascoside can significantly inhibit the replication of CVB3 on host cells, and reduce the release of myocar...
