Definitions
- the invention relates to the field of medical biotechnology, namely to the creation and production of natural virucidal disinfectants that are safe for human health, animals and the environment.
- a broad-spectrum antimicrobial viroseptic includes the well-known non-ionic detergent Triton-X-100, a solvent of tri- ⁇ -butyl phosphate, in a suspension of water / soybean oil (US 6034073 A, 03/07/2000). According to the authors of the development, such an antiseptic is active both against anthrax bacteria and against influenza viruses. It should be noted that Triton-X-100 is used to a greater extent for technological purposes as a detergent and emulsifier. The oil base of such antiseptics also does not seem convenient for individual use, and even more so for soaking napkins. Despite the imperfection of the composition, it is interesting to use emulsifiers to obtain stable emulsions of the main hydrophobic components of virucidal preparations. However, this antiseptic also does not meet environmental requirements.
- virucidal agents that contain a disinfecting agent, alcohol and / or water, while alkyldimethylbenzylammonium chloride (RU 2235558 CI; RU 2286145 C1), carbamide didecyldimethylammonium bromide (RU 2158143 C1), lactic acid, are used as a disinfectant. and a zinc-containing compound (RU 2436304 C2), an organic acid or an organic acid anhydride (RU 2366460 C2).
- a virucidal agent containing alkyldimethylbenzylammonium chloride, ethyl alcohol, propylene glycol, glycerin and grape seed oil, a 5.0-33.5% solution of tocopherol acetate and water in the following proportions, wt.%:
- alkyldimethylbenzylammonium chloride has an adverse side effect, polluting the environment.
- search for natural antiseptic compounds, the biodegradation of which in the environment, involves them in the natural processes of biotransformation and biodegradation is of particular relevance.
- the drug must be of natural origin and undergo biotransformation in nature or come from semi-synthetic substances of partially natural origin.
- norbornanes as natural compounds with high lipophilicity correspond to these criteria to the greatest extent.
- it is borneol and isoborneol that are the main active component of the bactericidal action.
- they are used in extremely high concentrations to inactivate bacteria (US 2008/0214518 A, 09/04/2008; El-Zemity. Synthesis and molluscitidial activity of novel N - methyl carbamate derivatives based on naturally occurring monoterpenoids. J. of Appl. Sci. Res ., 2006, Vol. 2 (2), p. 86 - 94).
- Borneols and isoborneols are the most common bicyclic compounds belonging to the class of monoterpenes.
- borneol the hydroxyl group is in the en position of endo-1, 7,7-Trimethyl-bicyclo [2.2.1] heptan-2-ol), and in isoborneol, it is in exo (ex-1, 7,7-Trimethyl- bicyclo [2.2.1] heptan-2-ol), that is, isoborneol is the exo-isomer of borneol (http://en.wikipedia.org/wiki/Borneol).
- borneol and isoborneol Due to the high hydrophobicity, borneol and isoborneol exhibit high lipophilicity and are therefore toxic in high concentrations to animal and human cells.
- Monoterpenes are an extensive class of compounds. No less wide is the spectrum of their action. Monoterpenes have antimicrobial and anti-inflammatory activity [McPartland J. M., Russo E.V. Cannabis and Cannabis extracts; greater than the sum of their parts? J. of Cannabis therapeutics. The Haworth Press, Inc. 2001, Vol. 1, p. 103-132], (http://www.cannabis-med.org/data/pdf/2001 -03-04-7.pdf).
- their previously unknown virucidal activity against type A influenza virus was established and their use with a fundamentally new purpose was proposed - to create a virucidal drug for sterilizing hands, face and surrounding household items.
- the invention is aimed at studying the properties of natural isoborneol and borneol and the creation on their basis of highly effective drugs that are active against current pandemic viruses, in particular the 2009 HlNl sw virus.
- the technical problem is solved by the use of isoborneol as a virucidal agent active against type A influenza viruses.
- the virucidal preparation according to the first embodiment contains a virucidal agent, ethyl alcohol and water, while it contains isobornoleol as a virucidal agent and additionally contains a polymer component that forms a complex with isobornoleol - polysorbitol, in the following ratio, wt.%:
- the virucidal preparation according to the second embodiment contains a virucidal agent, ethyl alcohol and water, while it contains a mixture of natural borneol and natural isoborneol in an equimolar amount and additionally contains a polymer component polysorbite, in the following ratio, wt.%:
- the drug according to any option may additionally contain a perfume additive in an amount of 0.05 ... 0.5 May. %
- the preparation according to any embodiment may contain at least one essential oil selected from the group: geranium oil, lime oil, lemon oil, bergamot oil, lemon oil.
- the preparation according to any embodiment may be in the form of a gel, or a spray, or an ointment, or a perfume product, or a paste.
- the created virucidal preparation meets all the above criteria, which is confirmed by the above examples.
- FIG. 1 shows the structural formulas of borneol (left) and isoborneol (right).
- FIG. 2 photographs illustrating the virucidal effect of isoborneol on a virus concentrate A / Duck / Potsdam (H5N2): left: bird flu virus concentrate A / Ducl / Potsdam (H5N2); rounded virions are visible, surrounded by a pronounced "brush" of surface antigens - receptors (HA, NA);
- FIG. 3 concentrate of avian influenza virus A / Duck / Potsdam (H5N2), exposed in a volume ratio of 1: 1 with 0, 1% isobornoleol solution for 10 min (final concentration of isobornoleol 0.05%); strong destruction of virions; arrows indicate dilapidated virions devoid of surface receptors; negative contrast, pH 7.0; scale segment of YuOnm.
- Solutions of borneol and isoborneol were prepared by dissolving crystalline substances in ethanol to prepare uterine concentrated solutions. As the first series of mother liquors, 5% solutions in 96% ethanol were used. As the second series of mother solutions, solutions of borneol or isoborneol at a concentration of 2.5% in 50% were used. ethyl alcohol. For testing, dilutions of the mother liquor from 2% to 0.01% with the appropriate dilution of ethyl alcohol were prepared. In solutions with borneol concentrations of 1%, the final concentration of ethyl alcohol was 20%. (All% mass).
- Ethanol in this concentration and below did not affect the infectivity of influenza viruses and did not lead to precipitation of proteins of the culture medium or allantoic fluid of chicken embryos. Stabilization of solutions at a low ethanol content, if necessary, was achieved by adding 10% polyethylene glycol or sodium alginate.
- Working solutions of virucidal preparations were prepared ex tempore by mixing the appropriate amounts of drugs (reagents), ethyl alcohol and water. The working solutions of the following concentrations were studied: from 0.01% to 10%. All prepared solutions were transparent and retained their properties for a long time at room temperature (observation duration up to 2 months).
- Table 1 shows the compositions of the preparations obtained.

- influenza viruses seasonal H1N1, H3N2 B
- avian influenza viruses H5N1 An analysis of the spread of the pandemic swine HlNl sw virus in the world since the spring of 2009 showed that the virus is actively spreading not only by airborne droplets, but also by contact.
- Viral particles are surrounded by a lipoprotein membrane, which includes lipids borrowed from the host cells, as well as surface proteins hemagglutinin (HA) and neuraminidase (HA), which play a key role in maintaining the infectious activity of virions.
- the surface of virions is a protein-lipid membrane highly sensitive to non-ionic detergents and any other lipophilic substances. Such substances include monoterpenes and, in particular, borneol or isoborneol.
- a strain of avian influenza virus was used as a test virus.
- the titer of the virus was taken to be the reciprocal of the decimal logarithm of the highest dilution of the virus, capable of inducing a positive hemagglutination reaction and expressed in the logarithms of 50% of the infectious dose of the virus (-lg ID 50 ).
- the infectious titer of the virus used in the experiment was 5.5 (-lg ID 50 ).
- HAO chorionallantoic membranes
- Virus-containing allantoic fluid was mixed in a 1: 1 ratio with the test agent in various concentrations and kept in sterile plastic tubes for 2-60 minutes at a temperature of 20 ⁇ 2 ° C.
- the level of virus reproduction in the panel wells after exposure to the drug and in the control was assessed by the hemagglutination reaction (RGA) of red blood cells.
- RAA hemagglutination reaction
- the residual infectious activity of the virus after exposure to the drug was evaluated by reducing the titer of the virus in the experiment compared with the control.
- TEM transmission electron microscopy
- a drop of the test drug was placed on the surface of a parafilm in a plastic Petri dish.
- a copper mesh with a carbon substrate was dropped onto a drop. After adsorption for 30-60 seconds. the mesh was washed in a drop of distilled water 2 times, then the preparation was contrasted with a 1.5% solution of potassium phosphoric tungsten acid (pH 6.7), excess fluid was removed with the edge of the filter paper, and the mesh with the preparation was dried for 1–2 minutes at room temperature .
- influenza virus concentrate obtained by precipitation of allantoic fluid on an L-8 ultracentrifuge (Beckman, USA) in the mode of 100 OOOg, 1, 5 hours.
- the viral concentrate was stored at -70 ° C in aliquots, and before testing, it was thawed and diluted with STE buffer solution (pH 7.4).
- the survey was performed on a FT-41MD sheet of photographic film; the negatives were scanned on an Epson 4870 scanner.
- the avian influenza virus on the example of the H5N2 virus and HlNlsw was completely inactivated in vitro with 0.01% -5.0% solution of funds for 2-30 minutes
- concentration of the tested agents is higher than 0.1%
- complete inactivation of the avian influenza virus was achieved in a very short time (less than 2 minutes).
- concentration of 0, 1% inactivation of the virus occurred in 10 minutes, which corresponds to the next interval of change.
- Allantoic fluid in terms of quantitative protein content is close to blood plasma; therefore, no additional in vitro experiments with protein loading were performed.
- norbornanes are hydrophobic substances, and the coefficient of their binding to proteins does not exceed 1%.
- the lipophilicity of these reagents makes them attractive to membranes, in this case, to the membranes of viral particles.
- the protective role of allantoic fluid components cannot be ruled out, therefore, on the smooth surface of materials or skin integument, the inactivation rate can increase significantly.
- Table 2 shows the residual infectious activity of the virus-containing allantoic fluid after exposure with isobornoleol and a mixture of isobornoleol + borneol.
- isoborneol and a mixture of isoborneol + borneol are characterized by a high level of virucidal activity and already at a concentration of 0.1% completely inactivate the influenza viruses H5N2 and HlNl sw - 2009 (pandemic isolate).
- TEM electron microphotograms
- FIG. Figure 4 shows the destroyed virions with elements of aggregation and "outpouring" of the nucleoid. Duration of exposure is indicated on microphotograms. Fundamental differences between exposure for 15 minutes or 1 hour. practically not observed. In fact, the destruction of virions occurs during the first 1 - 2 minutes. contact of a solution of isobornol with viral particles. Of considerable interest are mini-virus-like particles lacking internal (RNP) content. This processing method can be used to obtain immunogenic safe virus-like particles.
- RNP internal
- Isoborneol solutions have a rather pungent odor with a coniferous component. Borneol is especially inferior in this respect.
- the resulting disinfectant solutions are compatible with a repellent such as parametan-3,8-diol (p-methane-3,8-diol), which allows the proposed composition to be used as a disinfectant - repellent in conditions of danger of infection by an infection transmitted by insects, in particular mosquitoes, for example, Dengue fever (US 2007/0166342, 07.19.2007).
- a repellent such as parametan-3,8-diol (p-methane-3,8-diol)
- the drug has a natural origin, causes irreversible changes in the structure of viruses, has high bioavailability and does not cause irritation of the skin and mucous membranes. It is safe when it enters the gastrointestinal tract and can be stored for a long time.
