[57] ABSTRACT Novel keto-quaternary ammonium compounds which include the adamantane ring system linked to the quaternary ammonium group by a keto group.
4 Claims, No Drawings I KETO-QUATERNARY COMPOUNDS The present application is a continuation-in-part of copending application Ser. No. 400.097 filed Sept. 24. 1973, which is a continuation of patent application Ser. No. 39. 536 filed May 21. l970.'now abandoned.
The present invention relates to novel quaternary ammoniumcompounds represented by the general formula:
whereinR is l-am adantyl '(C Hi R is a long chain alkyl group of l l 8 carbon atoms, 11 is an integer from 1 to 3 and X is a compatible anion such as the halides (Cl' Br, I), sulfates (i.e.. methyl sulfateynitrate. aryl sulfonates, etc. The quaternary compounds possess superior anti-microbial. anti-caries and anti-calculus activity.
The adamantyl radical is derived from tricyclo- [3.3. l l ldeeane showing four fused chair cyelohexane rings as follows:
Typical examples of the quaternary ammonium compounds which may be used in this invention are: 2adamantylearbonylethyldimethyldeeylammonium bromide. 3-adamantylcarbonylpropyldimethyltetradecylammonium bromide, Z-adamantylcarbonylethyldimethylhexadecylammonium bromide, l-adamantylearbonylethyldimethyloctadeeylammonium bromide, l-adamantylcarbonylmethyldimethyltetradecylammonium bromide, l-adamantylcarbonylmethyldimethyldodecylammonium bromide. Other halides such as the chlorides, iodides and analogous compounds such as the sulfates, nitrate, aryl sulfonates, ctc.. may also be employed herein as effective anti-bactericides.
It has been observed that the compounds generally described by the foregoing formula are particularly effective against gram positive organisms such as Staphylococcus our-cur. Streptococcus mitis, Bacillus .s'ubti lis. Coryncbacterium acnes. and against fungi. such as Candida albicans, 'I'riclzop/zyrrm menlogrophytes and Aspergillus niger. and moderately effective against Ext-heric/n'a coli which is a gram negative bacterium. Compounds wherein R is a benzyl radical in lieu of instant higher alkyl radical would be devoid of anti-bacterial 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 inoculated 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.
In general. smaller concentrations of the subject compounds are required to inhibit the growth of the organisms than of analogous compounds which contain substantially the'same number of carbon atoms.
When used against bacteria or fungi. compounds of the instant invention may he applied directly to the surface to be protected or may be dissolved in a pharmaceutical carrier.'Typically. an effective amount, e.g. 0.] to about-10% by weight ofthe' eompound.-is included in an inert carrier and a dispersing or. surface active agent. Alternatively. an effective amount. eg 0.] to about' l0 /z 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 preparations in effective amounts up to about 5% by weight. preferably .025] '7! and most'preferably 0.050.5'/1'by weight of the oral preparation. Typically. the oral preparation is a dentrifrice. such as a dental cream. tablet or powder. containing as a vehicle about 20-95% by weight of a waterinsoluble polishing material. preferably including water-insoluble phosphate such as dicalcium phosphate, tricalcium phosphate. trimagnesium phosphate. The dentrifrice may also include water; binders such as glyeerine. sorbitol, propylene glycol. and polyethylene glycol 400; detergents; gelling agents such as Irish moss and sodium carboxymethyl cellulose; additional antibacterial agents. coloring or whitening agents; preservatives; silieones; chlorophyll compounds; additional ammoniated materials; flavoring or sweetening materials; and compounds which provide fluorine-containing ion such as sodium flouride, stannous flouride and sodium monofluorophosphate.
The oral preparation may also be a liquid such as mouth rinse which typically contains 20-997! by weight of an aqueous lower aliphatic alcohol, preperably having about 1-3071 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.
