Description

BACKGROUND OF THE INVENTION

[0002] The present invention relates to inhibiting the production of toxic shock syndrome toxin one (TSST-1) by Staphylococcus aureus. More particularly, the present invention relates to inhibiting the production of TSST-1 in the presence of non-absorbent articles, such as tampon applicators and incontinence devices, by incorporating certain compounds into or onto the non-absorbent product having an inhibitory effect on Gram-positive bacteria and the production of TSST-1.

[0003] There exists in the female body a complex process which maintains the vagina and physiologically related areas in a healthy state. In a female between the age of menarche and menopause, the normal vagina provides an ecosystem for a variety of microorganisms. Bacteria are the predominant type of microorganism present in the vagina; most women harbor about 109 bacteria per gram of vaginal fluid. The bacterial flora of the vagina is comprised of both aerobic and anaerobic bacteria. The more commonly isolated bacteria are Lactobacillus species, Corynebacteria, Gardnerella vaginalis, Staphylococcus species, Peptococcus species, aerobic and anaerobic Streptococcus species, and Bacteroides species. Other microorganisms that have been isolated from the vagina on occasion include yeast (Candida albicans), protozoa (Trichomonas vaginalis), mycoplasma (Mycoplasma hominis), chlamydia (Chlamydia trachomatis), and viruses (Herpes simplex). These latter organisms are generally associated with vaginitis or venereal disease, although they may be present in low numbers without causing symptoms.

[0004] Physiological, social, and idiosyncratic factors effect the quantity and species of bacteria present in the vagina. Physiological factors include age, day of the menstrual cycle, and pregnancy. For example, vaginal flora present in the vagina throughout the menstrual cycle can include lactobacilli, corynebacterium, ureaplasma, and mycoplasma. Social and idiosyncratic factors include method of birth control, sexual practices, systemic disease (e.g., diabetes), and medications.

[0005] Bacterial proteins and metabolic products produced in the vagina can effect other microorganisms and the human host. For example, the vagina between menstrual periods is mildly acidic having a pH ranging from about 3.8 to about 4.5. This pH range is generally considered the most favorable condition for the maintenance of normal flora. At that pH, the vagina normally harbors numerous species of microorganisms in a balanced ecology, playing a beneficial role in providing protection and resistance to infection and makes the vagina inhospitable to some species of bacteria such as Staphylococcus aureus (S. aureus). The low pH is a consequence of the growth of lactobacilli and their production of acidic products. Microorganisms in the vagina can also produce antimicrobial compounds such as hydrogen peroxide and bactericides directed at other bacterial species. One example is the lactocins, bacteriocin-like products of lactobacilli directed against other species of lactobacilli.

[0006] Some microbial products produced in the vagina may negatively affect the human host. For example, S. aureus is a bacteria that commonly colonizes human skin and mucous membranes. It causes disease in humans through invasion or through the production of toxic proteins. One such disease is toxic shock syndrome (TSS), caused by toxic shock syndrome toxin-1 (TSST-1) and other similar toxins. When absorbed into the blood stream, TSST-1 produces TSS in non-immune humans.

[0007] S. aureus is found in the vagina of approximately 16% of healthy women of menstrual age. Approximately 25% of the S. aureus isolated from the vagina are found to produce TSST-1. TSST-1 has been identified as causing TSS in humans.

[0008] Symptoms of TSS generally include fever, diarrhea, vomiting and a rash followed by a rapid drop in blood pressure. Multiple organ failure occurs in approximately 6% of those who contract the disease. S. aureus does not initiate TSS as a result of the invasion of the microorganism into the vaginal cavity. Instead as S. aureus grows and multiplies, it can produce TSST-1. Only after entering the bloodstream does TSST-1 toxin act systemically and produce the symptoms attributed to TSS.

[0009] Menstrual fluid has a pH of about 7.3. During menses, the pH of the vagina moves toward neutral and can become slightly alkaline. This change permits microorganisms whose growth is inhibited by an acidic environment the opportunity to proliferate. For example, S. aureus is more frequently isolated from vaginal swabs during menstruation than from swabs collected between menstrual periods.

[0010] When S. aureus is present in an area of the human body that harbors a normal microbial population such as the vagina, it may be difficult to eradicate the S. aureus bacteria without harming members of the normal microbial flora required for a healthy vagina. Typically, antibiotics that kill S. aureus are not an option for use in catamenial products because of their effect on the normal vaginal microbial flora and their propensity to stimulate toxin production if all of the S. aureus are not killed. An alternative to eradication is technology designed to prevent or substantially reduce the bacteria's ability to produce toxins.

[0011] There have been numerous attempts to reduce or eliminate pathogenic microorganisms and menstrually occurring TSS by incorporating into vaginal products one or more biostatic, biocidal, and/or detoxifying compounds. For example, L-ascorbic acid has been applied to a menstrual tampon to detoxify toxin found in the vagina. Others have incorporated monoesters and diesters of polyhydric aliphatic alcohols, such as glycerol monolaurate, as biocidal compounds (see, e.g., U.S. Pat. No. 5,679,369). Still others have introduced other non-ionic surfactants, such as alkyl ethers, alkyl amines, and alkyl amides as detoxifying compounds (see, e.g., U.S. Pat. Nos. 5,685,872, 5,618,554, and 5,612,045).

[0012] Despite the aforementioned attempts, there continues to be a need for compounds that will effectively inhibit the production of TSST-1 from Gram positive bacteria, and maintain activity even in the presence of the enzymes lipase and esterase which can have adverse effects on potency and which may also be present in the vagina. Further, it is desirable that the detoxifying compounds useful in the inhibition of the production of TSST-1 be substantially non-harmful to the natural flora found in the vaginal area. It is also desirable that the detoxifying compound be coated or otherwise introduced onto a non-absorbent substrate prior to use.

SUMMARY OF THE INVENTION

[0013] The present invention relates to non-absorbent substrates or products which comprise a compound for inhibiting the production of TSST-1 from Gram-positive bacteria. The compound-containing products are particularly useful for inhibiting the production of TSST-1 from S. aureus bacteria in the vaginal area. Examples of suitable non-absorbent products which can have the inhibitory compounds described herein incorporated thereon include non-absorbent incontinence devices, barrier birth control devices, douches, contraceptive sponges, and tampon applicators. One specific example of a non-absorbent incontinence device is a female barrier incontinence device, such as an incontinence pledget formed from a resilient material like rubber. Another suitable non-absorbent product is the applicator used with a tampon. For example, the tampon applicator may have one or more of the inhibitory compounds described herein coated on an outer surface, such that when the applicator is used to introduce a tampon into a women's vagina the inhibiting compound (typically in the form of a cream, wax, gel or other suitable form) is transferred from the applicator onto the wall of the vagina.

[0014] It is a general object of the present invention to provide a non-absorbent article or product which inhibits the production of TSST-1 from Gram positive bacteria. A more specific object of the present invention is to provide a non-absorbent incontinence device, a barrier birth control device, a contraceptive sponge, tampon applicator, or a douche incorporating one or more of the inhibitory compounds described herein which act to substantially inhibit the production of TSST-1 by S. aureus.

[0015] Another object of the present invention is to provide a non-absorbent substrate incorporating one or more inhibitory compounds described herein in combination with one or more other inhibitory ingredients such as, but not limited to, for example, aromatic compounds, isoprenoid compounds, laureth-4, PPG-5 lauryl ether, 1-0-dodecyl-rac-glycerol, disodium laureth sulfosuccinate, glycerol monolaurate, alkylpolyglycosides, polyethylene oxide (2) sorbital ether or myreth-3-myristate which in combination act to substantially inhibit the production of TSST-1 by S. aureus.

[0016] A further object of the present invention is to provide a non-absorbent substrate that has incorporated thereon or therein one or more compounds that will inhibit the production of TSST-1 from Gram positive bacteria without significantly imbalancing the natural flora present in the vaginal tract.

[0017] Therefore, the present invention is based on the discovery that when one or more compounds (used alone or in combination with other inhibitory compounds described herein) having the structure of any one of the Structures (I)-(III) below are incorporated into or onto a non-absorbent article, the production of TSST-1 in Gram positive bacteria is substantially inhibited.

[0060] The non-absorbent articles of the present invention containing a first inhibitory compound as described herein and a second inhibitory ether compound contain a sufficient amount of both inhibitory compounds to substantially inhibit the formation of TSST-1 when the non-absorbent article is exposed to S. aureus bacteria. Preferably, the combination of inhibitory compounds reduces the formation of TSST-1 when the non-absorbent article is exposed to S. aureus by at least about 40%, more preferably by at least about 50%, still more preferably by at least about 60%, still more preferably by at least about 70%, still more preferably by at least about 80%, still more preferably by at least about 90%, and still more preferably by at least about 95%.

The amount of first inhibitory compound of Structure (I), (II), and/or (III) is as described above.

[0062] In another embodiment, the inhibitory compounds of Structures (I), (II), and (III) are combined with an alkyl polyglycoside compound in the absorbent article. Suitable alkyl polyglycosides for use in combination with the inhibitory compounds of Structures of (I), (II), and (III) include alkyl polyglycosides having the following chemical structure:

H—(Zn)—O—R14  (VII)

[0063] wherein Z is a saccharide residue having 5 or 6 carbon atoms, n is a whole number from 1 to 6, and R14 is a linear or branched alkyl group having from about 8 to about 18 carbon atoms. Commercially available examples of suitable alkyl polyglycosides having differing carbon chain lengths include Glucopon 220, 225, 425, 600, and 625, all available from Henkel Corporation (Ambler, Pa.). These products are all mixtures of alkyl mono- and oligoglucopyranosides with differing alkyl group chain lengths based on fatty alcohols derived from coconut and/or palm kernel oil. Glucopon 220, 225, and 425 are examples of particularly suitable alkyl polyglycosides for use in combination with the inhibitory compounds of Structures (I), (II), and (III). Another example of a suitable commercially available alkyl polyglycoside is TL 2141, a Glucopon 220 analog available from ICI Surfactants (Wilmington, Del.).

[0064] It should be understood that as referred to herein, an alkyl polyglycoside may consist of a single type of alkyl polyglycoside molecule or, as is typically the case, may include a mixture of different alkyl polyglycoside molecules. The different alkyl polyglycoside molecules may be isomeric and/or may be alkyl polyglycoside molecules with differing alkyl group and/or saccharide portions. The term alkyl poyglycoside isomers includes alkyl polyglycosides which, although including the same alky ether residues, may vary with respect to the location of the alkyl ether residue in the alkyl polyglycoside as well as isomers which differ with respect to the orientation of the functional groups about one or more chiral centers in the molecules. For example, an alkyl polyglycoside can include a mixture of molecules with saccharide portions which are mono, di-, or oligosaccharides derived from more than one 6 carbon saccharide residue and where the mono-, di- or oligosaccharide has been etherified by reaction with a mixture of fatty alcohols of varying carbon chain length. The present alkyl polyglycosides desirably include alkyl groups where the average number of carbon atoms in the alkyl chain is about 8 to about 14 or from about 8 to about 12. One example of a suitable alkyl polyglycoside is a mixture of alkyl polyglycoside molecules with alkyl chains having from about 8 to about 10 carbon atoms.

[0065] The alkyl polyglycosides employed in the non-absorbent articles in combination with the inhibiting compounds described herein can be characterized in terms of their hydrophilic lipophilic balance (HLB). This can be calculated based on their chemical structure using techniques well known to those skilled in the art. The HLB of the alkyl polyglycosides used in the present invention typically falls within the range of about 10 to about 15. Desirably, the present alkyl polyglycosides have an HLB of at least about 12 and, more desirably, about 12 to about 14.

[0085] The present invention is illustrated by the following examples which are merely for the purpose of illustration and are not to be regarded as limiting the scope of the invention or manner in which it may be practiced.

EXAMPLE 1

[0086] In this Example, the effect of various test compounds on the growth of S. aureus and the production of TSST-1 was determined. The test compound, in the desired concentration (expressed in micrograms/milliliter) was placed in 10 mL of a growth medium in a sterile, 50 mL conical polypropylene tube (Sarstedt, Inc. Newton, N.C.).

[0087] The growth medium was prepared by dissolving 37 grams of brain heart infusion broth (BHI) (Difco Laboratories, Cockeysville, Md.) in 880 mL of distilled water and sterilizing the broth according to the manufacturer's instructions. The BHI was supplemented with fetal bovine serum (FBS) (100 mL) (Sigma Chemical Company, St. Louis, Mo.). Hexahydrate of magnesium chloride (0.021 M, 10 mL) (Sigma Chemical Company, St. Louis, Mo.) was added to the BHI-FBS mixture. Finally, L-glutamine (0.027 M, 10 mL) (Sigma Chemical Company, St. Louis, Mo.) was added to the mixture.

[0088] Compounds to be tested included hexachlorophene, triclosan and 4-hydroxydiphenyl methane. Test compounds were received as solids. The solids were dissolved in methanol, spectrophotometric grade (Sigma Chemical Company, St. Louis, Mo.) at a concentration that permitted the addition of 200 microliters of the solution to 10 mL of growth medium for the highest concentration tested. Each test compound that was dissolved in methanol was added to the growth medium in the amount necessary to obtain the desired final concentration.

[0089] In preparation for inoculation of the tubes of growth medium containing the test compounds, an inoculating broth was prepared as follows: S. aureus (MN8) was streaked onto a tryptic soy agar plate (TSA; Difco Laboratories Cockeysville, Md.) and incubated at 35° C. The test organism was obtained from Dr. Pat Schlievert, Department of Microbiology, University of Minnesota Medical School, Minneapolis, Minn. After 24 hours of incubation three to five individual colonies were picked with a sterile inoculating loop and used to inoculate 10 mL of growth medium. The tube of inoculated growth medium was incubated at 35° C. in atmospheric air. After 24 hours of incubation, the culture was removed from the incubator and mixed well on a S/P brand vortex mixer. A second tube containing 10 mL of the growth medium was inoculated with 0.5 mL of the above-described 24 hour old culture and incubated at 35° C. in atmospheric air. After 24 hours of incubation the culture was removed from the incubator and mixed well on a S/P brand vortex mixer. The optical density of the culture fluid was determined in a microplate reader (Bio-Tek Instruments, Model EL309, Winooski, Vt.). The amount of inoculum necessary to give 5×106 CFU/mL in 10 mL of growth medium was determined using a standard curve.

[0090] This Example included tubes of growth medium with varying concentrations of test compounds, tubes of growth medium without test compounds (control) and tubes of growth medium with 20-400 microliters of methanol (control). Each tube was inoculated with the amount of inoculum determined as described above. The tubes were capped with foam plugs (Identi-plug plastic foam plugs, Jaece Industries purchased from VWR Scientific Products, South Plainfield, N.J.). The tubes were incubated at 35° C. in atmospheric air containing 5% by volume CO2. After 24 hours of incubation the tubes were removed from the incubator and the optical density (600 nm) of the culture fluid was determined. The culture fluid was assayed for the number of colony forming units (CFU) of S. aureus using standard plate count procedures. The remaining culture fluid was prepared for the analysis of TSST-1 as follows: the culture fluid was centrifuged at 2500 rpm at about 2-10° C. for 15 minutes. The supernatant was filter sterilized through an Autovial 5 syringeless filter, 0.2 micrometer pore size (Whatman, Inc., Clifton N.J.). The resulting fluid was frozen at −70° C. in a Fisherbrand 12×75 millimeter polystyrene culture tube.

[0091] The amount of TSST-1 per mL was determined by a non-competitive, sandwich enzyme-linked immunoabsorbent assay (ELISA). Samples of the culture fluid and the TSST-1 reference standard were assayed in triplicate. The method employed was as follows: four reagents, TSST-1 (#TT-606), rabbit polyclonal anti-TSST-1 IgG (LTI-101), rabbit polyclonal anti-TSST-1 IgG conjugated to horseradish peroxidase (LTC-101), and normal rabbit serum (NRS) certified anti-TSST-1 free (NRS-10) were purchased from Toxin Technology (Sarasota, Fla.). A 10 microgram/milliliter solution of the polyclonal rabbit anti-TSST-1 IgG was prepared in phosphate buffered saline (PBS) (pH 7.4). The PBS was prepared from 0.016 molar NaH2PO4, 0.004 molar NaH2PO4—H2O, 0.003 molar KCl and 0.137 molar NaCl, (Sigma Chemical Company, St. Louis, Mo.). One hundred microliters of the polyclonal rabbit anti-TSST-1 IgG solution was pipetted into the inner wells of polystyrene microplates (Nunc-Denmark, Catalogue Number 439454). The plates were covered and incubated at room temperature overnight. Unbound anti-toxin was removed by draining until dry. TSST-1 was diluted to 10 nanograms/milliliter in PBS with phosphate buffered saline (pH 7.4) containing 0.05% (vol/vol) Tween-20 (PBS-Tween) (Sigma Chemical Company, St. Louis, Mo.) and 1% NRS (vol/vol) and incubated at 4° C. overnight. Test samples were combined with 1% NRS (vol/vol) and incubated at 4° C. overnight.

[0092] The plates were treated with 100 microliters of a 1% (wt/vol) solution of the sodium salt of casein in PBS (Sigma Chemical Company, St. Louis, Mo.), covered and incubated at 35° C. for one hour. Unbound BSA was removed by 3 washes with PBS-Tween. TSST-1 reference standard (10 nanograms/milliliter) treated with NRS, test samples treated with NRS, and reagent controls were pipetted in 200 microliter volumes to their respective wells on the first and seventh columns of the plate. One hundred microliters of PBS-Tween was added to the remaining wells. The TSST-1 reference standard and test samples were then serially diluted 6 times in the PBS-Tween by transferring 100 microliters from well-to-well. The samples were mixed prior to transfer by repeated aspiration and expression. This was followed by incubation for 1.5 hours at 35° C. and five washes with PBS-T and three washes with distilled water to remove unbound toxin.

[0093] The rabbit polyclonal anti-TSST-1 IgG conjugated to horseradish peroxidase wash diluted according to manufacturer's instructions and 50 microliters was added to each microtiter well, except well A-1, the conjugate control well. The plates were covered and incubated at 35° C. for one hour.

[0094] Following incubation the plates were washed five times in PBS-Tween and three times with distilled water. Following the washes, the wells were treated with 100 microliters of horseradish peroxidase substrate buffer consisting of 5 milligrams of o-phenylenediamine and 5 microliters of 30% hydrogen peroxide in 11 mL of citrate buffer (pH 5.5). The citrate buffer was prepared from 0.012 M anhydrous citric acid and 0.026 M dibasic sodium phosphate. The plates were incubated for 15 minutes at 35° C. The reaction was stopped by the addition of 50 microliters of a 5% sulfuric acid solution. The intensity of the color reaction in each well was evaluated using the BioTek Model EL309 microplate reader (OD 490 nanometers). TSST-1 concentrations in the test samples were determined from the reference toxin regression equation derived during each assay procedure. The efficacy of the compounds in inhibiting the production of TSST-1 is shown in Table I below.

[0095] In accordance with the present invention, the data in Table 1 shows that S. aureus (MN8), when compared to the control, produced significantly less TSST-1 in the presence of the hexachlorophene and triclosan compounds. At the concentration tested, these compounds reduced the amount of toxin produce by 68% to 88%. Although 4-hydroxydiphenyl-methane did reduce the toxin production by about 24%, it lacks the chlorine and hydrogen groups that have been shown to stabilize triclosan in the active site of the enzyme/NAD complex.

[0096] In this Example, the growth of, and TSST-1 production by, S. aureus FRI-1169 and 3 mutants able to grow in the presence of triclosan, was evaluated. S. aureus FRI-1169 was obtained as a lyophilized culture from the stock collection of Merlin Bergdoll (Food Research Institute, Madison Wis.). The mutants were selected by plating overnight growth of S. aureus FRI-1169 in growth medium onto tryptic soy agar plates containing 5 micrograms/milliliter triclosan. The effect of triclosan was determined by placing a range of concentrations, expressed in micrograms/milliliter, in 10 mL of growth medium as set forth in Example 1. The samples were then tested and evaluated utilizing the procedure set forth in Example 1. The effect of the triclosan on the growth of S. aureus FRI-1169 and on the production of TSST-1 is shown in Table 2.

[0097] In accordance with the present invention, the data shows that S. aureus FRI-1169, when compared to the control, produced less TSST-1 in the presence of triclosan. In addition, mutants selected for their ability to grow in the presence of triclosan showed a reduction in toxin production, compared to the parent strain, of 71%-95% in the presence of triclosan.

S. aureus FRI-1187 was obtained as a lyophilized culture from the stock collection of Merlin Bergdoll (Food Research Institute, Madison Wis.). The mutants were selected by plating overnight growth of S. aureus FRI-1187 in growth medium onto tryptic soy agar plates containing 5 microgram/milliliter triclosan. The effect of triclosan was determined by placing a range of concentrations, expressed in microgram/milliliter, in 10 mL of a growth medium as in Example 1. The samples were then tested and evaluated as in Example 1. The effect of the triclosan on the growth of S. aureus FRI-1187 and mutants and on the production of TSST-1 is shown in Table 3 below.

[0099] In accordance with the present invention, Table 3 shows that S. aureus FRI-1187, when compared to the control, produced less TSST-1 in the presence of triclosan. In addition, mutants selected for their ability to grow in the presence of triclosan showed a reduction in toxin production, compared to the parent strain, of 85%-94% in the presence of triclosan.
