Definitions
- the claimed invention relates to the development of a new substance - 4 - ((2-hydroxyethoxy) methyl) -5-methyl-2-methylmercapto-1, 2,4-triazolo [1,5-a] pyrimidine-7 (4H) -one having the formula
- West Nile supported by the circulation of the pathogen among small mammals, birds, mosquitoes and confirmed by the presence of an immune response to West Nile virus in the population (see Measures to Combat West Nile Fever in the Russian Federation (epidemiological surveillance, diagnosis, clinic, treatment and prevention) Methodical recommendations. - M., 2001).
- Ribavirin inhibits West Nile virus replication and cytopathic effect in neural cells // J. Infect. Dis. - 2000. - Vol. 182. - P.1214-1217.
- Shahar A. Lustig S., Akov Y. et al.
- Low molecular weight compounds are known in the art for the treatment and prophylaxis of West Nile fever, in particular the use of heterocyclic compounds (see patents MX2010013269, MX2011008988, WO2008124550, WO2010039538, WO2012135402, WO201 1137447, WO201214559567, RUO2321655967, RU). WO2010027996), synthetic nucleosides (see patents NZ588670, NZ579880, MX2009002707, US2012245335).
- the closest technical solution to the claimed invention is a compound - sodium salt of 2-methylthio-5-methyl-6-nitro-1, 2,4-triazolo [1, 5-a] pyrimidin-7 (ZAU) -one, which showed activity against causative agent of fever West Nile and other flaviviruses (see RF patent Ns 2365591 for the invention “A drug with antiviral effect and containing 2-methylthio-5-methyl-6-nitro-1, 2,4triazolo (1, 5-a) pyridin-7 ( ⁇ ) - ⁇ ”, filing date May 21, 2007, published August 27, 2009).
- the technical result of this invention is the creation of a new effective chemical compound with antiviral activity, in particular, against the causative agent of West Nile Fever (hereinafter - LZN).
- aprotic solvent for example, acetonitrile, methylene chloride, chloroform are used.
- the inventive compound (I) is a white crystalline substance, soluble in water, polar solvents such as methanol, dimethylformamide, dimethyl sulfoxide, acetone, but sparingly soluble in benzene, hexane and most non-polar solvents.
- polar solvents such as methanol, dimethylformamide, dimethyl sulfoxide, acetone, but sparingly soluble in benzene, hexane and most non-polar solvents.
- a monolayer cell culture GMK-AH (1D) was infected with West Nile virus at a dose of 0.05 PFU / cell. Virus adsorption was carried out at a temperature of 37 ° C with 5% CO 2 for 60 minutes. At the end of incubation, the monolayer was washed three times with a support medium containing 100 units / ml of penicillin and streptomycin to remove the non-adsorbed virus and the test compounds were added at a concentration of LA A of the IPC. RVL-346 was dissolved in DMSO until final concentration of 10 ⁇ g / ⁇ l and then diluted to the desired concentration of the supporting nutrient medium. At least 10 tubes with a monolayer of cells were used for each compound.
- Incubation was carried out at a temperature of 37 ° C, 5% C0 2 , for 48 hours.
- cryodestruction of the cells was performed and the samples were combined.
- the infectious titer in the pooled samples was determined by titration using the method of forming negative colonies under agar coating in a GMK-AN (1D) cell culture.
- the new chemical compound is non-toxic in the concentrations used, has significant in vitro antiviral activity against West Nile Fever virus.
