Description
i 148672
Til desinfektion og sterilisering af genstande, f.eks. lægeinstrumenter, egner sig såvel kemiske som fysiske fremgangsmåder. De fysiske fremgangsmåder, såsom varme- og dampsterilisering, anvendelse af ioniseret bestråling eller ultralyd har i praksis vist sig egnet, dog er deres almene anvendelighed begrænset af forskellige faktorer, såsom dyre instrumenter, fagpersonale, risiko ved usagkyndig håndtering.
De kemiske steriliseringsmetoder har den store fordel, at de kan anvendes universelt, og yderligere kan de være. billigere end de fysiske metoder. En væsentlig ulempe ved de kendte fremgangsmåder er dog giftigheden af mange af de hertil anvendte forbindelser, f.eks. giftigheden af ethylenoxid og den karcinogene virkning af β-propiolacton. Blandt de mindre giftige kemiske stoffer er der mange, der er velegnede som desinfektionsmidler på grund af deres gode baktericide egenskaber, men der kendes kun få miljøvenlige desinfektionsmidler, som samtidig har sporicid virkning.
Nogle aldehyder har såvel baktericid som sporicid virkning.
Hertil hører specielt formaldehyd, glyoxal, glutardialdehyd og andre mættede dialdehyder, jf. DE offentliggørelsesskrift nr.
14 92 326. Anvendelsen af disse aldehyder til sterilisationsformål er dog forbundet med forskellige ulemper. Formaldehyd har i den krævede koncentration en ubehagelig vedhængende lugt, glyoxal har ingen tilstrækkelig baktericid virkning, glutardialdehyd og andre mættede dialdehyder har en ubehagelig skarp lugt og hertil kommer, at de først udfolder deres sporicide virkning i svagt alkalisk miljø, hvori de ikke er bestandige i længere tid.
Fra Farmakologija i Toksikologija, 28, 66-69 (1965) kendes et desinfektionsmiddel indeholdende 2,5-dimethøxydihydrofuran Det anføres,at dihydrofuranforbindelsen har virucid virkning in vitro, men intet om en sporicid eller fungicid virkning.
Det har nu vist sig, at visse substituerede tetrahydrofu-randerivater overraskende besidder god baktericid, fungicid - samt sporicid virkning.
148672 2
Opfindelsen angår således e-£ desinfektionsmiddel med sporicid virkning, som er ejendommeligt ved et indhold af 2,5-dialkoxy- tetrahydrofuranderivater med den almene formel f^O —Γ ”j- OR2 0 1 2 hvori R og R kan være ens eller forskellige og betegner alkylgrupper med 1-4 carbonatomer. Som eksempler på alkyl-1 2 grupper R og R kan nævnes methyl, ethyl, n-propyl, i-propyl, n-butyl, sek.-butyl og tert.-butyl.
Ét særligt foretrukket eksempel på de ifølge opfindelsen 1 2 anvendte tetrahydrofuraner, hvoraf sådanne, hvor R og R betyder en methyl-, ethyl-, n-propyl-, iso-propyl- eller n-butylgruppe,er kendte forbindelser, er 2,5-dimethoxytetrå-hydrofuran (2,5-DMO—THF).
Uetrahydrofuranderivateme kan fremstilles ved katalytisk hydrogenering af de tilsvarende dihydrofuranderivater (J. Arner. Chem. Soc.
72, 869 (1952)) eller ved ozonolyse af cyklododecatrien-(1,5,9) i nærværelse af den tilsvarende alkohol og efterfølgende katalytisk hydrogenering af det dannede ozonid (JA-pa-tentskrift nr. 71/19 930.
Et foretrukket anvendelsesområde for midlerne ifølge opfindelsen er desinfektions- og steriliseringssektoren, dvs. den såkaldte koldsterilisering af instrumenter og redskaber samt termolabile formstoffer, først og fremmest i sygehuse og i lægepraksis. En behagelig lugt og en god vandopløselighed af de virksomme stoffer er af betydning for steriliserings- 148672 3 midler på dette område. De i praksis for tiden foretrukne midler består af tokomponentsystemer på basis af glutardi-aldehyd og alkali, som dog er ufordelagtige i håndteringen og på grund af deres lugt.
De i midlerne ifølge opfindelsen indeholdte dialkoxytetra- · hydrofuranderivater har såvel en behagelig lugt som en meget god vandopløselighed. Alkoholer kan eventuelt tjene som opløsningsfremmende midler. Begge egenskaber påvirkes naturligvis 12 af substituenterne R og R . Alt afhængigt af substituenterne er lugten fra svag og behagelig til behagelig frugtagtig-etherisk. Specielt, når der anvendes koncentrationer på <2 vægt?i,er lugten behagelig, hvis den overhovedet kan spores.
Bestandigheden af midlerne ifølge opfindelsen er også væsentlig. Selv efter lang tids lagring ser man hverken en ændring af de fysiske egenskaber eller en aftagende virkning.
I de omhandlede midler kan dialkoxytetrahydrofuraner blandes med en række andre aktive stoffer og giver så kraftigt virkende desinfektionsmidler med stærk sporicid virkning. Som blandingskomponenter kan f.eks. nævnes: 1. primære, sekundære og tertiære mono- eller polyvalente alifatiske alkoholer, hvorhos alkoholkomponenten kan være erstattet helt eller delvis med vand. Eksempler er methanol, ethanol, n-propanol, isopropanol, ethylenglycol og glycerol, 2. mono- og dialdehyder, såsom formaldehyd, glyoxal og glu-tardialdehyd, 3. overfladeaktive forbindelser fra gruppen ikke-ionogene, anioniske, kationiske og amfolytiske detergenter, 4. antimikrobielt virksomme organiske syrer, såsom mælkesyre, citronsyre og myresyre, 148672 4 5. specielle substituerede phenoler, såsom 2,6-dimethyl-4-bromphenol, 6. rhodanider, såsom natrium-, kalium- eller ammoniumrhodanid, 7. korrosionsbeskyttelsesmidler, såsom phosphater, borater, silikater og benzoater, og endvidere 1,2,3-benzotriazol og 2-mercaptobenzoxazol.
Virkningen af midlerne ifølge opfindelsen opnås også i høje fortyndinger, fortrinsvis anvendes imidlertid koncentrationer af diaIkoxytetrahydrofuranderivater, som er af størrelsesorde- -nen 0,1 - 1 vægtft til den baktericide og fungicide virkning, og 0,1 - 4 vægt/ό (fortrinsvis 2 vægt«) til den sporicide virkning.
De følgende forsøg belyser opfindelsen.
Sammenlignings forsøg.
Bestemmelsen af den baktericide og fungicide virkning skete i suspensionsforsøg efter retningslinierne for afprøvning af kemiske desinfektionsmidler (Deutschen Gesellschaft fiir Hygiene und Mikrobiologie (3. oplag, 1972). Bestemmelsen af den sporicide virkning skete i kimbærerforsøg, ligeledes efter DGHM-retningslinierne.
