Definitions

  • This invention relates to anti-viral composi ⁇ tions , and more particularly to anti-viral compositions for external topical application to mammalian skin.
  • Viral transmission from body to body as a result of body surface contact and body fluid intermingling is one of the principal ways in which viruses such as hepatitis, herpes, HIV and the like are spread.
  • health workers such as ambulance personnel, nurses, doctors, operations theatre attendants and the like, who must administer to and consequently frequently engage in body contact with virally infected persons.
  • the most commonly recommended form of protection against such viral infections has been the protective skin barrier method namely the use of latex gloves by health care workers and the use of latex condoms by those exposed to sexually transmitted viruses.
  • the present invention provides an anti-viral gel formulation for use in conjunction with viral barrier items such as latex gloves and condoms.
  • the formulation contains a very small, skin acceptable amount of a strong disinfec ⁇ tant or antiseptic substance, formulated into a semi-solid, gel consistency with aqueous based, skin acceptable carrier materials, for application to mammalian skin under viral barrier items such as latex• gloves and condoms.
  • the disinfectant or antiseptic substance kills the harmful virus on contact, even in the necessarily small concentra ⁇ tions required to render the compositions of the present invention skin acceptable.
  • the user is accordingly pro ⁇ vided with a double protection against viral infection from an infected body which must be contacted, namely the viral barrier item and the antiseptic or disinfectant gel beneath it.
  • a latex barrier item adapted to be fitted over a body part to inhibit viral transmission thereto, said latex barrier item having an outer surface and an inner surface to contact the body part, said inner surface having a layer of semi-solid, anti-viral gel or cream comprising an alkyl benzyl quaternary ammonium halide disinfectant in an amount of from about 0.005-0.1% by weight, a non-ionic or cationic surfactant in an amount of from about 0.01-0.1% by weight, and a lubricious non-toxic hypoallergenic water compatible thickener in an amount chosen to give semi-solid, creamy consistency to the composition, and water.
  • an alkyl benzyl quaternary ammonium halide disinfectant in an amount of from about 0.005-0.1% by weight
  • a non-ionic or cationic surfactant in an amount of from about 0.01-0.1% by weight

  • the alkyl benzyl quaternary ammonium halide disinfectants used in the present invention are known compounds, many of which have previously been sold and used for disinfecting purposes in non-skin contacting applica ⁇ tions. Thus, they are sold for purposes of making up disinfectant wash solutions for floors, walls, operating surfaces and the like, but always with strong warnings to avoid skin contact with them if at all possible. They are powerful poisons and skin irritants, as well as powerful disinfectants. According to the present invention, they will destroy harmful viruses such as hepatitis, herpes simplex types 1 and 2 and HIV when they are present in formulations in such low concentrations that they are skin acceptable. These viruses in fact are not difficult to kill when encountered in isolation in external body fluids or secretions.
  • the strong disinfectant is preferably used in the composi ⁇ tion of the present invention in amounts from 0.005-0.5% by weight, most preferably from 0.005-0.001% by weight.
  • Specific examples of such strong disinfectants for use in the present invention include alkyl dimethyl benzyl ammon ⁇ ium chloride and alkyl dimethylethylbenzyl ammonium chlor ⁇ ide, in which the alkyl portions are C 12 -C 18 in length, and mixtures thereof, and myristylbenzalkonium chloride.
  • Such a suitable mixture is available commercially under the trade name MAQUAT MQ2525M - 50%, from Mason Chemical Company, Chicago, Illinois, and under the trade name BTC 2125M from Stepan Company, North Field, Illinois.
  • compositions according to the present invention also include a small amount of a non-ionic or cationic surfactant to act as a wetting agent for the disinfectant. This improves the spreading of the disinfectant over the skin area to which it is applied.
  • the surfactant is suitably present in amounts similar to those of the disin ⁇ fectant, i.e. 0.01-0.1% by weight, preferably 0.01-0.05% by weight.
  • Examples of specific useful surfactants of these classes include the polyoxyethylene - based types such as those of the octoxynol series , which are polyethylene glycol p-isooctylphenyl ethers such as octoxynol-9 (Triton X - 100), those of the nonoxynol series, which are polyoxy ⁇ ethylene nonylphenyl ethers, of various numbers of ethylene oxide units, e.g. nonoxydol 9 and nonoxydol 10. These have the advantage for use in the present invention in that they also have spermatocidal properties.

  • Virus controls were prepared in the same way by pipetting 0.2 ml HBV into 2.0 ml phosphate buffered saline (PBS). The reaction mixtures were concentrated by ultracentrifugation with appropriate sucrose gradients, the supernatant gently poured off, and the pellets were re-suspended with a 0.5 ml PBS, with similar pellets being combined.
  • the HBV particles were purified by late-zonal ultracentrifugation in a 60-5% linear gradient (sucrose), and fractionated. Dane particle fractions having a refractive index between 1.396 and 1.404 were saved and pooled.
  • Negative staining was used to detect morphologi ⁇ cally altered virions. For this, 5% uranyl acetate in water, at pH 3.5, was used, with blotting. Thirty or more fields from six randomly selected squares were observed with a Philips transmission electron microscope, and thoroughly enumerated for each of the four alteration phases AP0, API, AP2 and AP3. No morphologically intact virions were observed, only highly morphologically altered, AP2 and AP3 forms, which are non-infectious. In contrast, the control samples evidenced the great majority of virions to be morphologically intact and in the infectious (AP0 or API) phases.

Filtered viral stocks were aliquoted and stored at -85°C until used. The virus stock was determined by an end point titration method using MT-2 cells in a 96-well microtiter plate configuration. The virus stock contained a TCID 50 virus titer of 5.50 log 10 TCID 50/ml calculated by the Reed-Muench method.
  • MT-2 cells in exprudential growth phase were exposed to various dilutions of compounds. After 4 days, the cell viability was assessed by the Tryptan-Glu exclusion method and compared to controls without drug.
  • Virus stocks were thawed and diluted with phos ⁇ phate buffered saline to obtain the required amounts of virus necessary for inactivation assay experiments. Untreated virus served as the TCID 50 control for this experiment. After a one minute exposure of HIV-1 with the compound, sequential ten-fold dilutions of the treated or untreated virus control were prepared in PBS and each dilution was used to infect MT-2 cells as previously described. Virus expression was monitored by the presence of syncytium formation. HIV-induced syncytium formation was assessed after 6 days of culture using a syncytium- formation assay.
