Embodiment 1

[0031]Embodiment 1. Separation and extraction of a new dammarane type triterpene saponin Notoginsenoside ST-4 (notoginsenoside ST-4):

[0032] 5kg Panax notoginseng was purchased in Yunnan, crushed into granules, wrapped with double gauze, placed in a pressure cooker, controlled at a high temperature of 120°C, and steamed for 12 hours to obtain cooked Panax notoginseng. Reflux extraction with industrial ethanol (5L×4), recover the solvent under reduced pressure and concentrate to obtain 778g of total extract. Dissolve the extract in water, perform column chromatography twice with D101 macroporous adsorption resin (90×8.5 cm), first elute with water until the Molish reaction of the effluent is negative, and then elute with industrial methanol to obtain 440 g of crude saponin.

[0033] The crude saponin was mixed with about 500 g of silica gel (200-300 mesh), and subjected to column chromatography on silica gel (200-300 mesh), eluted with chloroform-methanol-water (85:15:1), and...

Embodiment 2、 3

[0044] Example 2, the effect test of notoginsenoside ST-4 (notoginsenoside ST-4) on the infection of Vero cells by herpes simplex virus type I (HSV-1):

[0045] (1) Materials:

[0046] 1. Equipment: imported 24-well culture plate (flat bottom), inverted microscope, CO 2 Cell incubator, micro-adjustable sample injector, medium is MEM (containing 250U / ml blue chain double antibody), adjust pH to 7.0-7.2 with sodium bicarbonate before sterilization and filtration, and sterilize calf serum at 56°C for 30min Live complement, sterilized and aliquoted; the digestive solution is 5% trypsin 5ml+0.01mol / L (pH 7.2) PBS 93ml, sterilized and aliquoted, and stored at low temperature.

[0047] 2. Viruses and cell strains: Herpes simplex virus type 1 strains are from ATCC (VR733) in the United States and are kept by the applicant's laboratory. MRC-5 cells were purchased from the Cell Bank of the Chinese Academy of Sciences and kept by the applicant's laboratory. The MRC-5 cell line comes f...

Embodiment 3

[0072] Tablet: 10 mg of the compound Panax notoginsenoside ST-4 obtained in Example 1, 180 mg of lactose, 55 mg of starch, and 5 mg of magnesium stearate;

[0073] Preparation method: mix the compound, lactose and starch, moisten it evenly with water, sieve the wetted mixture and dry it, then sieve it, add magnesium stearate, then press the mixture into tablets, each tablet weighs 250mg, and the compound content is 10mg .

Abstract

The invention discloses a notoginsenoside ST-4 which is a new dammarane type triterpenoid saponin compound shown in the structural formula (I), and a preparation method thereof. The invention also provides applications of the notoginsenoside ST-4 in the preparation of drugs against HSV-1. An HSV-1 strain and HELF (MRC-5) are used as cell experimental subjects to carry out the experiment of antiviral activity of the new compound which is the notoginsenoside ST-4. The results show that the notoginsenoside ST-4 has therapeutical effect for cells infected by HSV-1 and can reduce the infectivity of HSV-1 for MRC-5 cells and be applied to the preparation of drugs against HSV-1.

Description

technical field [0001] The present invention relates to the field of pharmaceutical compounds and medicines, in particular to a new dammarane-type triterpene saponin compound notoginseng saponin ST-4 and a preparation method thereof, and the compound is used to prepare anti-herpes simplex virus type I (HSV -1) Use of the drug. Background technique [0002] Herpes simplex virus is a DNA virus that belongs to the subfamily Aviridae of the family Herpesviridae. According to the difference of antigenicity, it can be divided into type I and type II. Herpes simplex virus type 1 (HSV-1) primarily causes infections of the skin, mucous membranes (oral mucosa) and organs (brain) other than the genitals. The clinical manifestations are mainly localized herpes on the mucous membrane or skin, and occasionally serious systemic diseases may occur, involving internal organs. After the primary infection of herpes simplex is cured, the virus gene is latent in the ganglion. When the body's ...
