The present invention relates to novel quaternary ammonium compounds represented by the general formula:
wherein R is l-adamantyl (C H R is an aliphatic chain containing -18 carbon atoms, n is an integer from 2 to 3 and X is a compatible anion such as the halides (Cl,Br',l), sulfates (i.e., methyl sulfate), nitrate, aryl sulfonates, etc. These quaternary compounds possess superior antimicrobial, anti-caries, and anticalculus activity.
The adamantyl radical is derived from tricyclo[3.3.1.l "']decane showing four fused chair cyclohexane rings as follows:
Typical examples of the quaternary ammonium compounds which may be used in this invention are:
2-( l -adamantyloxy)ethyldimethyldodecyl ammonium bromide,
2-( l -adamantyloxy)ethyldimethyltetradecyl ammonium bromide,
2-( l-adamantyloxy)ethyldimethyldecyl ammonium chloride,
2-( l-adamantyloxy)ethyldimethylhexadecyl ammo- 1 nium chloride, 2-( l -adamantyloxy)ethyldimethyloctadecyl ammonium chloride, 3-( l -adamantyloxy)propyldimethyldodecyl ammonium bromide. Other halides such as the iodides and analogous compounds such as the sulfates, nitrate, aryl sulfonates, etc., may also be employed herein as effective antibactericides.
It has been observed that the compounds generally described by the foregoing formula are particularly effective against a wide range of organisms including the gram positive organisms such as Staphylococcus aureus; Streptococcus mitis, sanguis and mutans; Bacillus subtilis; Corynbacterium acnes; and especially effective against fungi, such as Candida albicans, Trichophyton mentogrophytes and Aspergillus niger, and against Escherichia coli which is a gram negative bacteria. Compounds wherein R is a benzyl radical in lieu of instant higher alkyl radical would be devoid of antibacterial activity.
The anti-microbial nature of the instant novel compounds was shown by a standard test tube serial dilution test in which an appropriate number of test tubes of broth containing decreasing concentrations of the test agent was innoculated with the test organism. After a suitable period of incubation, the tubes were examined for the presence or absence of growth. The activity of the test agent was the lowest concentration which inhibited the growth of the organism and is expressed as the minimal inhibitory concentration in ug/ml.
These dilution tests evidence the effectiveness of compounds of the invention against bacteria and fungi.
When used against bacteria or fungi, compounds of the instant invention may be applied directly to the surface to be protected or may be dissolved in a pharmaceutical carrier. Typically, an effective amount, e.g., 0.1 to about 10 percent by weight of the compound, is included in an inert carrier and a dispersing or surfaceactive agent. Alternatively, an effective amount, e.g., 0.1 to about 10 percent by weight may be incorporated into a solid carrier which may be inert, such as talc, clay, diatomaceous earth, flour, etc.
When compounds of the instant invention are intended for use in compositions which reduce formation of caries and inhibit formation of oral calculus, they are typically incorporated in oral preparation in effective amounts up to about 5 percent by weight, preferably 0.025-1 percent and most preferably 0.5-0.5 percent by weight of the oral preparation. Typically, the oral preparation is a dentifrice, such as a dental cream tablet or powder, containing as a vehicle about 20-95 percent by weight of a water-insoluble polishing material, preferably including water-insoluble phosphate such as dicalcium phosphate, tricalcium phosphate, trimagnesium phosphate. The dentrifrice may also include water; binders such as glycerine, sorbitol, propylene glycol and polyethylene glycol 400; detergents; gelling agents such as lrish moss and sodium carboxy methyl cellulose; additional antibacterial agents; coloring or whitening agents; preservatives; silicones; chlorophyll compounds; additional ammoniated materials; flavoring or sweetening materials; and compounds which provide fluorine-containing ion such as sodium fluoride, stannous fluoride and sodium monofluorophosphate- The oral preparation may also be a liquid such as mouth rinse which typically contains 20-99 percent by weight of an aqueous lower aliphatic alcohol, preferably having about l-30 percent by weight alcohol, such as ethanol, n-propyl, or isopropyl alcohol.
Such oral preparations are typically applied by brushing the teeth or rinsing the oral cavity for 30-90 seconds at least once daily. Typical oral preparations of the invention which can be applied in this manner are set forth below.
