The invention relates to the field of biologically active compounds, medicine, in particular of Virology and chemotherapy of viral infections, and can be used to suppress the reproduction of influenza viruses and the reduction caused by disease.

Famous hydrochloride 1-aminomethyl-and-methyladenine (rimantadine) [1, 2], effectively suppressing the reproduction of influenza viruses and is used in several countries as a means of treatment and prevention of influenza. Lack of rimantadine is relatively low activity [3].

A wider range of non-toxic concentrations (doses) with antiviral action has hydrochloride 1-aminoadamantana (amantadine) [4], (adopted for the prototype), also used as a medicinal antiviral drug. The disadvantage of amantadine is significant side effects on the Central nervous system and reduced in some cases the activity [3].

Object of the invention is the extension of the range of agents with antiviral action.

This object is achieved by the use of amino adamantanol number of General formula

The study of the toxic properties of the claimed compounds.

The toxic properties determined by the ability to cause cytodestructive changes of cells after 72 h of incubation. Monolayer cell culture of primary trypsinization of fibroblasts of chicken embryos (FEC) is washed from the growth medium and to cause the breeding of amino adamantane on the environment support (medium 199) with a concentration of 800 μg/ml or less. Upon expiration of the specified period unpainted culture viewed at low magnification (X10 lens). The maximum tolerable concentration (MBC) adopt high concentration of substances that do not cause these changes. Establish that the compounds I, IV and V region is give the ability to cause cytodestructive cells in the concentration range from 400 μg/ml or less, compounds II and VII is in the range of concentrations of 100 μg/ml and below, compound VI is at a concentration of 50 μg/ml and below, the compound III is at a concentration of 12.5 μg/ml and below.

Example 9

The antiviral activity of the claimed compounds.

The study was conducted by the method of reduction of the number of plaques under the agar surface. Monoclonal culture FEC grown in vials, washed from the growth environment, infect various dilutions of influenza virus A/FPV/Rostock/34 (H7N1) in the range from 0.01 to 0,00001 PFU/cell by applying vaccinated suspension in a volume of 0.1 ml for 1 h at 37°C. the liquid is Then removed and the cells are covered with molten nutrient coatings based on concentrate medium 199 supplemented with 1% of bactiera and 0.005% neutral red (all reagents Sigma) and different concentrations of the studied compounds. After hardening the coating on the bottles placed in a thermostat at 36 h and then count the number of plaques that are visible due to the presence in the coating of the vital dye. Based on the number of plaques calculate the titer of the virus. Criterion antiviral actions consider the existence of differences in comparison with control virus. Calculate the concentration of 50 and 95% suppression of viral replication (average effective and 95% effective concentration EC and ES respectively) and the relationship IPC/ES and IPC/ES (index selectivity).

P the obtained results are shown in the table.

Antiviral properties of synthesized compounds against influenza virus A/FPV/Rostock (H7N1)

As can be seen from the table, all investigated compounds effectively inhibit the replication of influenza virus in cell cultures. The widest range of effective non-toxic concentrations is connected VII (relationship IPC/EC50and IPC/EU95=385,8 and 18.5, respectively). Somewhat less he expressed the compounds II (relationship IPC/EU50and IPC/EU95=84,2 and 20.1, respectively) and I (relationship IPC/EU50and IPC/EC95=27,4 and 13.9, respectively). All of the claimed compounds exceed the comparator drug (amantadine) the ratio of IPC/EU95(index selectivity), and the connection I is also the ratio of IPC/EC50.

Thus, the inventive solution allows to solve the problem. When using the new amino derivatives adamantanol series manages to obtain a high selectivity of antiviral action against influenza virus. Used when performing studies with influenza virus A/FPV/Rostock (H7N1) is a model representative viruses of the genus Influenzavirus And when the study of the antiviral properties of synthetic and natural compounds [5], i.e. the presence and gibiruei properties in relation to the reproduction of the virus means, what activity spectrum of the analyte of interest applies to all influenza viruses A.

This property involves the use of the inventive compounds for the treatment and prevention of diseases caused by including highly pathogenic virus of avian influenza (H7N1) and A (H5N1).

The flu is most dangerous epidemic among infections caused by RNA genome viruses. In Russia annually more than 7 million cases of influenza infection, which is about 20% in the structure of infectious and parasitic diseases in the population. Feature of influenza virus (especially influenza) is the ability of the rapid emergence of new varieties due to antigenic variation. This is due to the complexity in the development of influenza vaccines, and become resistant to existing drugs of influenza virus strains. Influenza viruses of type a can infect not only humans, but some species of animals and birds, including chickens, ducks, pigs, horses, ferrets, seals and whales. Along with circulating in the human population by serotypes of influenza a (H3N2 and H1N1) serious concerns arise from avian viruses, which is the most pathogenic. The pathogens that cause highly pathogenic avian influenza viruses of subtypes H5 and H7 hemagglutinin. So, to date the avian flu is A(H5N1) causes the greatest number of cases of severe disease in birds fatal and potentially dangerous for people periodically there have been outbreaks of the disease, mainly by the staff of the poultry farms and persons closely in contact with poultry, including fatalities.

Highly pathogenic avian influenza is a very contagious disease that can cause 100% mortality of livestock. So, in 1983-1984, in the U.S. as a result of the outbreak of avian influenza was destroyed 17 million birds, and the economic damage amounted to $ 65 million. In 1999-2001 in Italy, the spread of the disease caused by the virus avian influenza(H7N1), led to the destruction of 13 million birds. Increasing cases of avian influenza A (H5N1) in Southeast Asia and other geographic regions, including on the territory of the Russian Federation, as well as the possibility of the emergence of this pathogen's ability to spread in the human population by respiratory (pathogen transmission from person to person) testify about the danger of a pandemic variants of this virus.

In addition, vaccination against highly pathogenic influenza a (H5N1) and A(H7N1) carries a huge risk of spreading the disease to other farms due to incomplete suppression of the infection. In this regard, many countries have imposed a ban on vaccination against avian influenza.

Therefore, the only means of combating these vozbuditel the mi is the creation of a highly effective chemotherapeutic drugs, having a high activity, bioavailability and low toxicity.

The identity of the virus of avian influenza a (H5N1) and A (H7N1) on the grounds of belonging to the same family and genus of viruses and caused disease, determines the fact that the drugs presented derived from a number of adamantane, effective for the treatment of infections caused by influenza a, including A (H7N1), also effective against virus a(H5N1) virus [6]. As shown in the example of a study of amantadine and rimantadine in the spectrum antiviral action of anti-influenza drugs based on adamantane derivatives are most strains of influenza virus And human rights, including contemporary influenza viruses A(H3N2) and A (H1N1) [7-9].

The invention can be used in medicine and veterinary medicine. To develop final recommendations on the application of the inventive amino adamantane for the treatment and prevention of influenza, the necessary study of the safety, development of dosage forms, clinical (in-situ) testing and development of optimal schemes of application.
