Description

BACKGROUND OF THE INVENTION

[0001] Outer layers of plants such as leaf cuticles, fruit peels, and bark protect the plant against abrasion, prevent water loss, and protect against pathogenic microorganisms. Breaking through the plant protective outer layer is a prerequisite for a pathogen to enter the plant's internal tissues. Some studies have suggested that penetration of the protective layer involves dissolution of the host cuticle by enzymes secreted by the pathogen Nicholson, R. L et al., in The Fungal Spore and Disease Initiation in Plants and Animals, eds. Cole, G. T, and Hoch, H. C., 1991, Plenum Press, New York, pp. 3-23.

[0002] Pentacyclic triterpenes are among the most common plant secondary metabolites, but their function in plants has not been fully understood. They are usually concentrated in the outermost layers such as plant cuticle, fruit peel, and bark.

[0003] Betulin is a pentacyclic triterpenoid derived from the outer bark of paper birch trues (Betula papyrifera, B. pendula, B. venucosa, etc.). It can be present at concentrations of up to about 24% of the bark of white birch Merck Index, twelfth edition, page 1236 (1996). Lupeol is a related compound also found in birch bark and in other plant sources. Lupeol is present at concentrations of about 1.5-3% of the birch bark and at up to about 8.2% in Canavalia ensiformis, a plant widespread in the humid tropics of Asia and Africa. Allobetulin is another triterpenoid found in birch bat A typical pulp mill that process birch produces enough bark waste to allow for the inexpensive isolation of significant quantities of these triterpenoids.

[0004] Literature supplies examples of enzymes that can be inhibited by triterpenes, indicating the ability of triterpenes to act broadly in a non-specific mode on multiple targets. For example, Buehler et al. (Biochem. Biophys. Acta 1075, 206 (1991) showed inhibition of rat renal 11.beta.-hydroxysteroid dehydrogenase. Koch et al. (Phytother, Res. 8, 109 (1994)) showed in vitro inhibition of adenosine deaminase. This leads to the hypothesis that pentacyclic triterpenoids in plant protective outer layers may protect against infection by inhibiting enzymes that would degrade the cuticle.

[0005] Several triterpenoids have been found to have utility. For example, betulin and related compounds have been shown to have anti-viral activity against herpes simplex virus. Carlson et al., U.S. Pat. No. 5,750,578. Betulin and related compounds have also been shown to have anti-fungal and anti-bacterial activity. However, triterpenoids are hydrophobic compounds with relatively low interfacial activity and water solubility. For instance, the solubility of betulin in water is about 0.15 mg/l. The relatively low interfacial activity and water solubility can make handling and administration of the compounds difficult. Low interfacial activity also limits the efficient interaction with target (fingi or bacteria) cell membranes. It also limits accessibility to hydrophilic biological targets or targets protected by a hydrophilic barrier.

[0006] There is a need for new compounds with anti-fungal, and anti-bacterial activities. Preferably the compounds would be relatively water soluble surfactants. The water-soluble compounds would retain their utility, e.g., antifungal, antibacterial, etc., activity.

SUMMARY OF THE INVENTION

[0007] The present invention provides novel compounds useful for their anti-fungal and antibacterial properties. The compounds have the advantage of being derived from abundant and relatively inexpensive staring materials. They have the further advantage of being based on natural compounds, and thus being less likely to pose a risk to the environment, humans, or beneficial organisms. They have the flier advantage of being relatively water soluble and amphiphilic. This makes the compounds easier to handle and reduces the use of hazardous organic solvents. It also increases accessibility to hydrophilic biological targets, or to targets present in water or protected by a hydrophilic barer. The amphiphilic character of the compounds allows them to bind hydrophobic targets, and may allow them to adsorb on cytoplasmic membranes. A further advantage of the compounds is that they are stable and do not tend to readily hydrolyze.

[0008] The present invention provides a quaternary ammonium salt of a triterpene.

R.sub.2 is (C.sub.1-C.sub.24)alkyl. R.sub.3 is absent or (C.sub.1-C.sub.24)alkyl or is alkylcarbonyl attached through the carbonyl to the oxy at the 3 or 28 carbon of betulin, lupeol, or allobetulin, or to an imino or thio in place of the oxy at the 3 or 28 carbon of betulin, lupeol, or allobetulin, wherein if it is attached to an oxy, imino, or thio at the 28 carbon of allobetulin, carbon 19 is a methylene. In particular embodiments of compound VII, two R.sub.1s are (C.sub.6-C.sub.24)alkyl. In particular embodiments of compound VII, at least two R.sub.1s are (C.sub.8-C.sub.24)alkyl or (C.sub.10-C.sub.24)alkyl. In particular embodiments of compound VIII, at least two R.sub.1s attached to either nitrogen atom are (C.sub.6-C.sub.24)alkyl. In particular embodiments of compound VIII, at least two R.sub.1s attached to either nitrogen atom are (C.sub.8-C.sub.24)alkyl or C.sub.10-C.sub.24)alkyl. Any alkyl or alkylcarbonyl can optionally be substituted with one or more oxo, hydroxy, mercapto, or NR.sub.dR.sub.e. R.sub.d and R.sub.e are each independently hydrogen or alkyl. The compound in this case comprises at least two moieties selected from the group of betulin, allobetulin, and lupeol.

[0144] In one specific embodiment of the compound of formula (VI), the compound is N,N,N',N'-tetramethylethylenediamine-N,N'-bis-[lup-20(29)-ene-3-acetate].

[0145] The compounds of the invention include one or more triterpene moieties covalently attached via a linker to a quaternary ammonium salt. The linker can attach to the triterpene moiety at any suitable position of the triterpene. The linker can attach to the quaternary ammonium salt at the N.sup.+ atom or at any other suitable position. The linker can be, for instance, alkylene, alkylcarbonyl, alkoxy, alkylimino, oxyalkylcarbonyl, carbonylalkylcarbonyl, or carbonylalkyloxy.

[0146] The quaternary ammonium salt can also be attached directly to the triterpene without a linker. The attachment in this case can be at any suitable position of the triterpene and any suitable position of the quaternary ammonium salt.

[0147] Processes for preparing compounds of formulas (I)-(IV) are provided as further embodiments of the invention and are illustrated by the following procedures in which the meanings of the generic radicals are as given unless otherwise qualified. Specifically, the compounds of formulas (I)-(IV) can be prepared from convenient starting materials, employing procedures (e.g., reagents and reaction conditions) known to those of skill in the art. For example, suitable reagents and reaction-conditions are disclosed, e.g., in Advanced Organic Chemistry, Part B: Reactions and Synthesis, Second Edition, Cary and Sundberg (1983); Advanced Organic Chemistry, Reactions, Mechanisms, and Structure, Second Edition, March (1977); Protecting Groups in Organic Synthesis, Second Edition, Greene, T. W., and Wutz, P. G. M., John Wiley & Sons, New York; and Comprehensive Organic Transformations, Larock, R. C., Second Edition, John Wiley & Sons, New York (1999).

[0148] The compounds of the invention, e.g., compounds of formulas (I)-(IV), can be formulated as compositions for the treatment or prevention of fungal or bacterial infections of plants. Generally, the compositions comprising compounds of the invention will be applied topically to the plants, generally by spraying. The compositions can also be injected into the plant or applied to the soil for uptake into the plant through the root system. The compositions can comprise an acceptable vehicle, such as an inert diluent or a carrier that facilitates uptake into the plant. Acceptable vehicles are known in the art. Methods of formulating anti-fungal compounds for spraying onto plants are disclosed, for instance in Glinsky et al. (U.S. Pat. No. 6,303,589 B1).

[0149] If desired, the compounds of the invention may be applied in conjunction with one or more intert or active ingredients. Exemplary materials include dyes, additives affecting stability of the compositions, additives affecting physical properties of the sprayed layer, foliar fertilizers, fungicides, and insecticides.

[0150] The compounds of the invention, e.g. compounds of formulas (I)-(IV), are also useful for cosmetic treatment of nails and adjacent skin infected with fungus in humans. In cosmetic treatment, the compounds of the invention are applied topically to the affected nails and adjacent skin either alone or in a composition with an acceptable carrier. The compounds of the invention can be applied with one or more other inert or active ingredients.

[0151] Acceptable salts may be obtained using standard procedures well known in the art, for example by reacting a sufficiently basic compound such as an amine with a suitable acid affording an acceptable anion.

[0152] The compounds of formulas (I)-(IV) can be formulated as pharmaceutical compositions and administered to a mammalian host, such as a human patient, in a variety of forms adapted to the chosen route of administration. Typically, the pharmaceutical compositions will be administered topically. They may also be administered, e.g., orally or parenterally, and by intravenous, intramuscular, or subcutaneous routes.

[0153] Thus, the present compounds may be systemically administered, e.g., orally, in combination with a pharmaceutically acceptable vehicle such as an inert diluent or an assimilable edible carrier. They may be enclosed in hard or soft shell gelatin capsules, may be compressed into tablets, or may be incorporated directly with the food of the patient's diet. For oral therapeutic administration, the active compound may be combined with one or more excipients and used in the form of ingestible tablets, buccal tablets, troches, capsules, elixirs, suspensions, syrups, wafers, and the like. Such compositions and preparations should contain at least 0.11% of active compound. The percentage of the compositions and preparations may, of course, be varied and may conveniently be between about 2 to about 60% of the weight of a given unit dosage form. The amount of active compound in such therapeutically useful compositions is such that an effective dosage level will be obtained.

[0154] The tablets, troches, pills, capsules, and the like may also contain the following: binders such as gum tragaceath, acacia, corn starch or gelatin; excipients such as dicalcium phosphate; a disintegrating agent such as corn starch potato starch, alginic acid and the like; a lubricant such as magnesia stearate; and a sweetening agent such as sucrose, fructose, lactose or aspartame or a flavoring agent such as peppermint, oil of wintergreen, or cherry flavoring may be added. When the unit dosage form is a capsule, it may contain, in addition to materials of the above type, a liquid carrier, such as a vegetable oil or a polyethylene glycol. Various other materials may be present as coatings or to otherwise modify the physical form of the solid unit dosage form. For instance, tablets, pills, or capsules may be coated with gelatin, wax, shellac or sugar and the like. A syrup or elixir may contain the active compound, sucrose or fructose as a sweetening agent, methyl and propylparabens as preservatives, a dye and flavoring such as cherry or orange flavor. Of course, any material used in preparing any unit dosage form should be pharmaceutically acceptable and substantially non-toxic in the amounts employed. In addition, the active compound may be incorporated into sustained-release preparations and devices.

[0155] The active compound may also be administered intravenously or intraperitoneally by infusion or injection. Solutions of the active compound or its salts can be prepared in water, optionally mixed with a nontoxic surfactant. Dispersions can also be prepared in glycerol, liquid polyethylene glycols, triacetin, and mixtures thereof and in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms.

[0156] The pharmaceutical dosage forms suitable for injection or infusion can include sterile aqueous solutions or dispersions or sterile powders comprising the active ingredient which are adapted for the extemporaneous preparation of sterile injectable or infusible solutions or dispersions, optionally encapsulated in liposomes. In all cases, the ultimate dosage form should be sterile, fluid and stable under the conditions of manufacture and storage. The liquid carrier or vehicle can be a solvent or liquid dispersion medium comprising, for example, water, ethanol, a polyol (for example, glycerol propylene glycol, liquid polyethylene glycols, and the like), vegetable oils, nontoxic glyceryl esters, and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the formation of liposomes, by the maintenance of the required particle size in the case of dispersions or by the use of surfactants. The prevention of the action of microorganisms can be brought about by various antibacterial and antifungal agents for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars, buffers or sodium chloride. Prolonged absorption of the injectable compositions can be brought about by the use in the compositions of agents delaying absorption, for example, aluminum monostearate and gelatin.

[0157] Sterile injectable solutions are prepared by incorporating the active compound in the required amount in the appropriate solvent with various of the other ingredients enumerated above, as required, followed by filter sterilization. In the case of sterile powders for the preparation of sterile injectable solutions, the preferred methods of preparation are vacuum drying and the freeze drying techniques, which yield a powder of the active ingredient plus any additional desired ingredient present in the previously sterile-filtered solutions.

[0158] For topical administration, the present compounds may be applied in pure form, i.e., when they are liquids. However, it will generally be desirable to administer them to the skin as compositions or formulations, in combination with a dermatologically acceptable carrier, which may be a solid or a liquid.

[0159] Useful solid carriers include finely divided solids such as talc, clay, microcrystalline cellulose, silica, alumina and the like. Useful liquid carriers include water, alcohols or glycols or water-alcohol/glycol blends, in which the present compounds can be dissolved or dispersed at effective levels, optionally with the aid of non-toxic surfactants. Adjuvants such as fragrances and additional antimicrobial agents can be added to optimize the properties for a given use. The resultant liquid compositions can be applied from absorbent pads, used to impregnate bandages and other dressings, or sprayed onto the affected area using pump-type or aerosol sprayers.

[0160] Thickeners such as synthetic polymers, fatty acids, fatty acid salts and esters, fatty alcohols, modified celluloses or modified mineral materials ca also be employed with liquid carriers to form spreadable pastes, gels, ointments, soaps, and the like, for application directly to the skin of the user.

[0161] Examples of useful dermatological compositions which can be used to deliver the compounds of formula I to the skin are known to the art; for example, see Jacquet et al. (U.S. Pat. No. 4,608,392), Geria (U.S. Pat. No. 4,992,478), Smith et al. (U.S. Pat. No. 4,559,157) and Wortzman (U.S. Pat. No. 4,820,508).

[0162] Useful dosages of the compounds of formulas (I)-(IV) can be determined by comparing their in vitro activity, and as vivo activity in animal models. Methods for the extrapolation of effective dosages in mice, and other animals, to humans are known to the art for example, see U.S. Pat. No. 4,938,949.

[0163] The ability of a compound of the invention to act as an antibacterial or antifungal agent may be determined using pharmacological models which are well know to the art, including the tests described in the Examples below.

[0164] The compounds of the invention may also be useful as pharmacological tools for the further investigation of the mechanism of their antibacterial or antifungal action.

[0165] The compounds of the invention can also be administered in combination with other therapeutic agents that are effective to treat bacterial or fungal infections, or to inhibit or kill bacteria or fungi.

[0166] The compounds of the invention possess a rigid and hydrophobic fused pentacyclic ring portion, and a hydrophilic quaternary amine portion. Because of their amphiphilic character, they are also useful as surfactants. Their activity as surfactants may be the basis for their antibacterial and antifungal activities, by for instance, adsorbing to cytoplasmic membranes.

Results

[0422] The lowest concentration which inhibits bacterial growth is referred to as the minimum inhibitory concentration (MIC), the standard measurement of anti-microbial activity. Table 1 gives approximate MIC values for the 19 triterpenes tested. The standard for antibiotic development in the pharmaceutical industry is that compounds under study must be active at 10 .mu.g/ml or less to be considered for further development. By this criterion, all five of the quaternary amine triterpene derivatives tested were effective against both S. aureus and E. faecium. In addition, the compounds were approximately equally effective against both antibiotic-resistant and antibiotic-sensitive strains of the two bacteria. In contrast, of the triterpenes not derivatized with a quaternary amine, only lupeol-3-maleate had an MIC of 10 .mu.g/ml or less, and that against only one strain of bacteria.

Methods.

[0423] Plots of creeping bentgrass, cv. "Pennlinks," were treated with water based sprays of the test compounds. Sprays were delivered by CO.sub.2-charged sprayer to deliver the equivalent of 2 gallons of spray per 1000 sq. ft of plot area. Plots were 15 sq. ft. each, and treatments were mixed to apply material to 75 sq. ft (5 replicates), although only 4 replicates were treated. The quaternary salts of triterpenes were applied at 17.8 g/1000 sq. ft. for 14 days. Daconil Ultrex.RTM. was applied at 3.2 oz/1000 sq. ft. for 14 days. The experiment used a randomized complete block design, with 4 replicates per treatment. Disease pressure was high. Pennlinks bluegrass is moderately to highly susceptible to both dollar spot and brown patch. For brown patch, caused by Rhozoctonia sofani, a visual estimate of the percent of the plot area affected was recorded. Turf quality was estimated on a 1 to 9 scale, with 1 being worst and 9 being perfect A rating of 6 is considered acceptable.

Results.

[0424] Table 2 and Table 3 report the results of two experiments. The compound numbers in the Tables correspond to the Example numbers above. In Table 3, compounds 15 and 24 suppressed the development of brown patch after the first spray was applied. The other treatment suppressed brown patch also, but to a lesser extent on Jun. 25, 2001, one week after the first treatment was applied. At Jul. 2, 2001, compounds 1, 15, and 24 suppressed dollar spot, but not as well as the chemical standard, Daconil Ultrex.RTM.. By Jul. 9, 2001, none of the treatments differed significantly from the control for dollar spot.

[0425] On June 25 and Jul. 2, 2001 in Table 3, all of the test compounds apparently deceased brown patch, but only compound 15 (on June 25) and Daconil Ultrex.RTM. achieved stastically significant suppression. By Jul. 9, 2001, compounds 7, 18, and 24 were judged to significantly suppress brown patch. On July 16, there were no significant differences regarding brown patch.

[0426] In summary, for the first two weeks, all of the tested quaternary amine salts of triterpenes suppressed both dollar spot and brown patch for the first two weeks of treatment in one of the studies. In the study of Table 2, for die compounds appeared to be less effective. Many reasons might account for this, in particular weather and soil conditions.

Methods

[0428] Plots of creeping bentgrass, cv. Pennlinks, were treated with water-based sprays as in Example 84 at Clemson University. Treatment application dates were May 7, May 14, May 28, and June 11. Plots were rated visually, estimating the percent of the area affected by dollar spot fungus (Agrotis stolonifera). Turf quality was rated on a 1 to 9 scale, with 9 being perfect turf, as in Example 84. Disease pressure was moderately high to high when the trial was initiated, with existing dollar spot present. Plots did not receive additional innoculum, as it was not needed.
