Embodiment 1

[0029] [Example 1] Research experiment on anti-ADV7 activity of polyiodoaromatic acid compounds L4~L7

[0030] The experimental situation is as follows:

[0031] 1. Test content:

[0032] Anti-ADV7 activity analysis of compounds: In the present invention, the anti-ADV7 activity of polyiodocarboxylic acids will be evaluated by combining cytopathic effect analysis and MTT assay cell survival rate detection method.

[0033] 2. Test method:

[0034] 2.1.1 Toxicity of compounds to host Hela cells

[0035] Hela cells were plated in 96-well plates at 37°C, 5% CO 2 After the monolayer was grown in the incubator, the cell culture solution was discarded, and the cell maintenance solution containing different concentrations of the test compound was added to continue the culture. After 48 hours, the cytotoxicity was visually observed under the microscope and recorded respectively, and the cell survival rate was determined by the MTT method. SPSS 11.5 software calculates the median tox...

Embodiment 2

[0046] [Example 2] The inhibitory effect test of polyiodoaromatic acid compounds L4, L5, L7 on the yield of ADV7 progeny virus

[0047] This embodiment has carried out in-depth research on the anti-ADV7 activity of polyiodocarboxylic acids (L4~L7), and implemented the inhibitory effect test of compounds L4, L5, and L7 on the production of ADV7 progeny virus, and the test conditions are as follows:

[0048] 1. Test content

[0049] After ADV7 infected Hela cells, the inhibitory effect of compounds L4, L5, and L7 on the production of ADV7 progeny virus was detected.

[0050] 2. Test method

[0051] Hela cells in the logarithmic growth phase were plated in 24-well plates, and 100TCID after the monolayer was overgrown 50 ADV7 infected cells, incubated at 37°C for 1.5h, removed the virus solution, washed three times with PBS, and added 200 μg / mL L4, 50 μg / mL L5, and 100 μg / mL L7 cell maintenance solution. After 48 hours, the cells and supernatant were collected and lysed by free...

Abstract

The invention discloses a polyiodinated aromatic acid compound and an application thereof in resisting adenovirus type 7. Anti-ADV7 virus activity research experiments of polyiodinated carboxylic acidcomprising 3-amino-4-iodobenzoic acid (L4), 3,4-diiodobenzoic acid (L5), 3,5- diiodosalicylic acid (L6) and 2,3,5-triiodobenoic acid (L7) show that the compounds L4, L5 and L7 inhibit cytopathic effect (CPE) generated by ADV7 on host cells Hela, the cell survival rate is increased, the yield of filial generation viruses is reduced, and the compounds can be applied to preparation of anti-ADV7 virus drugs.

Description

technical field [0001] The invention relates to the technical field of antiviral drugs, and specifically refers to a polyiodoaromatic acid compound and its application in anti-adenovirus type 7. Background technique [0002] Adenoviruses (adenoviruses, ADVs) are a group of widely distributed DNA viruses. There are 52 known species of somatic adenoviruses, named ADV1-ADV52 respectively, divided into two genera, with a total of more than 100 serotypes. About one-third of the known serotypes of human adenoviruses are associated with human disease. Adenoviruses can invade various tissues and organs such as the respiratory tract, conjunctiva, gastrointestinal tract, and urinary tract. The main infection is the respiratory tract. In severe cases, it can cause pneumonia in children and accumulate in various systems of the body. Adenoviral pneumonia caused by adenovirus infection is one of the most serious types of pneumonia in children. The adenovirus types associated with respi...
