Embodiment 1

[0021] Embodiment 1: Arbidol hydrochloride is to the cytotoxicity of HEp-2 cell and HEL cell

[0022] Use trypsin to disperse well-grown HEp-2 cells and HEL cells into a single cell suspension, press 1×10 5 / ml concentration in 96-well plate, 0.1ml per well, set at 37°C, 5% CO 2 Cultivate in the incubator for 24h. After the cells grow into a single layer, the supernatant of the culture medium is discarded and replaced with a drug-containing maintenance solution of different concentrations. Four replicate wells are set for each concentration, and normal cells are set as a control. Continue culturing for 48 h, discard the culture supernatant, add 50 μl of serum-free MEM medium containing 5 mg / ml MTT (tetramethylazozolium salt) to each well, and place in CO 2 After continuing to culture in the incubator for 2-3 hours, discard the MTT supernatant, wash 3 times with PBS, add 100 μl of dissolving solution (DMSO:ethanol volume ratio: 1:1) to each well, shake for 5-10 minutes, and s...

Embodiment 2

[0031] Embodiment 2: Arbidol hydrochloride anti-Coxsackie virus effect in vitro

[0032] It is proposed that the effect of Arbidol hydrochloride on CVB3 is divided into four groups. Group I (drug antiviral biosynthesis group): first add virus liquid to adsorb cells for 2 hours, then add drug-containing maintenance liquid. Group II (drug direct action group): the virus solution reacted with different concentrations of drugs for 2 hours, and then the mixed solution was incubated with the cells for 2 hours, and then the cell maintenance solution was replaced. Groups III and IV (drug antiviral adsorption 2h, 8h groups): After adding different concentrations of drugs into the cells for 2h and 8h respectively, the drug solution was discarded, and the virus solution was added, and the cell maintenance solution was replaced after 2 hours of adsorption.

[0033] Four replicate wells were set in each well of the above four experimental groups, and uninfected cell control, virus control...

Embodiment 3

[0039] Embodiment 3: Arbidol hydrochloride anti-adenovirus Ad7 effect in vitro

[0040] It is proposed that the effect of Arbidol hydrochloride on adenovirus Ad7 is divided into four groups. Group I (drug antiviral biosynthesis group): first add virus liquid to adsorb cells for 2 hours, then add drug-containing maintenance liquid. Group II (drug direct action group): the virus solution reacted with different concentrations of drugs for 2 hours, and then the mixed solution was incubated with the cells for 2 hours, and then the cell maintenance solution was replaced. Groups III, IV, and V (2h, 4h, and 8h groups of drug antiviral adsorption): add different concentrations of drugs into the cells for 2h, 4h, and 8h respectively, discard the drug solution, add virus solution, and absorb After 2 h, the cell maintenance solution was replaced.

[0041] Four replicate wells were set for each well of the above five groups of experimental groups, and uninfected cell control, virus contr...

Abstract

The present invention discloses a medicine with obvious antiviral effect for resisting coxsackie virus, adenovirus Ad7, parafinflueza virus and rhinovirus. Said invention also provides the general formula of said medicine.

Description

technical field [0001] The invention relates to a new antiviral drug Arbidol hydrochloride and the anti-multiple respiratory virus effects of the drug. Specifically, the present invention belongs to a new compound with good antiviral activity, and the application of the compound in the preparation of anti-coxsackie virus B3, adenovirus Ad7, parainfluenza virus and rhinovirus drugs. Background technique [0002] Influenza and acute respiratory virus infection are diseases with a high clinical incidence and a wide range of diseases. Due to the antigenic variability of influenza virus and its multi-drug resistance, a safe and effective drug for treatment and prevention is urgently needed. Chemical drugs play an extremely important role in the treatment of influenza and ARVI. So far, amantadine and amantadine derivative rimantadine have been widely used clinically as antiviral drugs, but their activity range is narrow (only effective against influenza A virus), and they have si...
