Description
Denne oppfinnelse angår nye penicillansyre-l-oksyder for anvendelse som utgangsmateriale ved fremstilling av terapeutisk aktivt penicillansyre-1,1-dioksyd. This invention relates to new penicillanic acid 1-oxides for use as starting material in the production of therapeutically active penicillanic acid 1,1-dioxide.
En av de mest velkjente og en meget anvendt gruppe av antibakterielle midler er de såkalte g-laktam-antibiotika. One of the most well-known and a widely used group of antibacterial agents are the so-called g-lactam antibiotics.
Disse forbindelser er karakterisert ved at de har en kjerne bestående av en 2-azetidinon (/3-laktam) -ring knyttet til enten en tiazolidin- eller en dihydro-1,3-tiazin-ring. Når kjernen inneholder en tiazolidin-ring, omtales vanligvis forbindelsene med fellesnavnet penicilliner, mens når kjernen inneholder en di-hydrctiazin-ring, omtales forbindelsene som cefalosporiner. Typiske eksempler på penicilliner som er vanlig anvendt ved klinisk praksis, er benzylpenicillin (penicillin G), fenoksy-metylpenicillin (penicillin V), ampicillin og carbenicillin, og typiske eksempler på vanlige cefalosporiner er cefalotin, cefalexin og cefazolin. These compounds are characterized in that they have a nucleus consisting of a 2-azetidinone (β-lactam) ring linked to either a thiazolidine or a dihydro-1,3-thiazine ring. When the core contains a thiazolidine ring, the compounds are usually referred to by the common name penicillins, while when the core contains a dihydrctiazine ring, the compounds are referred to as cephalosporins. Typical examples of penicillins commonly used in clinical practice are benzylpenicillin (penicillin G), phenoxymethylpenicillin (penicillin V), ampicillin and carbenicillin, and typical examples of common cephalosporins are cefalotin, cephalexin and cefazolin.
På tross av den omfattende anvendelse og omfattende god-tagelse av 3-laktam-antibiotika som verdifulle kjemoterapeutiske midler, så lider de likevel av den hovedmangel at et visst antall av dem ikke er aktive mot visse mikroorganismer. Man har tenkt at denne motstand til en spesiell mikroorganisme mot et gitt (3-laktam-antibiotikum i mange tilfeller oppstår på grunn av at mikroorganismen produserer en g-laktamase. Den sistnevnte substans er et enzym som spalter $-laktam-ringen i penicilliner Despite the extensive use and widespread acceptance of 3-lactam antibiotics as valuable chemotherapeutic agents, they nevertheless suffer from the main drawback that a certain number of them are not active against certain microorganisms. It has been thought that this resistance of a particular microorganism to a given (3-lactam antibiotic in many cases arises because the microorganism produces a γ-lactamase. The latter substance is an enzyme that cleaves the $-lactam ring in penicillins
og cef alosporiner slik at det dannes produkter som er fri for antibakteriell aktivitet. Visse substanser har imidlertid evne til å inhi-bere 8-laktamase, og når en B-laktamase-inhibitor anvendes sammen med et penicillin eller cefalosporin kan den øke eller forhøye den antibakterielle effektivitet til penicillinet eller cefalosporinet mot visse mikroorganismer. Det anses for å være en forhøyelse av and cefalosporins so that products are formed that are free of antibacterial activity. However, certain substances have the ability to inhibit 8-lactamase, and when a B-lactamase inhibitor is used together with a penicillin or cephalosporin, it can increase or increase the antibacterial effectiveness of the penicillin or cephalosporin against certain microorganisms. It is considered to be an elevation of
antibakteriell effektivitet når den antibakterielle aktivitet til en kombinasjon av en Ø-laktamase-inhiberende substans og et Ø-laktam-antibiotikum er betydelig større enn summen av de antibakterielle aktiviteter til de enkelte komponenter. antibacterial effectiveness when the antibacterial activity of a combination of a β-lactamase-inhibiting substance and a β-lactam antibiotic is significantly greater than the sum of the antibacterial activities of the individual components.
Forsøk er i den senere tid gjort på å finne frem til penicillinforbindelser som er resistente overfor Ø-laktamaser. Dette har ført til utvikling av slike antibiotika som methacillin, oxacillin, cloxacillin, dicloxacillin og floxacillin. Disse forbindelser er imidlertid klinisk nyttige bare mot gram-positive bakterier, og de har bare lav aktivitet sammenlignet med penicilliner så som benzyl-penicillin og fenoksymetyl-penicillin, midler som vanligvis anvendes mot gram-positive infeksjoner. Dessuten vil ikke methacillin, oxacillin, cloxacillin, dicloxacillin og floxacillin forsterke den antibakterielle virkning av andre penicilliner eller cefalosporiner mot gram-negative organismer. Forbindelsene som fremstilles ved hjelp av de nye utgangsmaterialer ifølge foreliggende oppfinnelse, forsterker den antibakterielle aktivitet av penicilliner og cefalosporiner mot både gram-positive og gram-negative bakterier. Attempts have recently been made to find penicillin compounds that are resistant to Ø-lactamases. This has led to the development of such antibiotics as methacillin, oxacillin, cloxacillin, dicloxacillin and floxacillin. However, these compounds are clinically useful only against gram-positive bacteria, and they have only low activity compared to penicillins such as benzyl penicillin and phenoxymethyl penicillin, agents commonly used against gram-positive infections. In addition, methacillin, oxacillin, cloxacillin, dicloxacillin and floxacillin will not enhance the antibacterial action of other penicillins or cephalosporins against gram-negative organisms. The compounds produced using the new starting materials according to the present invention enhance the antibacterial activity of penicillins and cephalosporins against both gram-positive and gram-negative bacteria.
Chaikovskaya et al, Antibiotiki, 13, 155 (1968) har undersøkt en rekke /3-laktamase-inhibitorer, men fant ingen andre forbindelser enn methicillin med nyttig aktivitet. Spesielt var benzyl-penicillin-1,1-dioksyd fullstendig in-aktiv. Chaikovskaya et al, Antibiotics, 13, 155 (1968) have examined a number of β-lactamase inhibitors but found no compounds other than methicillin with useful activity. In particular, benzyl penicillin-1,1-dioxide was completely inactive.
Senere er clavulansyre, en /3-laktam-forbindelse oppnådd fra Streptomyces clavuligerus, funnet å være en god Ø-laktamase-inhibitor. Sistnevnte forbindelse er imidlertid kjemisk ustabil. Forbindelsene som fremstilles ved help av utgangsmaterialene ifølge foreliggende oppfinnelse, er betydelig mer stabile enn clavulansyre. Later, clavulanic acid, a β-lactam compound obtained from Streptomyces clavuligerus, has been found to be a good β-lactamase inhibitor. However, the latter compound is chemically unstable. The compounds produced with the help of the starting materials according to the present invention are significantly more stable than clavulanic acid.
I henhold til oppfinnelsen ifølge norsk patent-søknad 78.1970 er det således tilveiebragt en fremgangsmåte for fremstilling av visse nye kjemiske forbindelser som er nye medlemmer av den gruppe av antibiotika som er kjent som penicilliner, og som er nyttige som antibakterielle midler. Disse nye penicillin-forbindelser er penicillansyre-1,1-dioksyd, farmasøytisk godtagbare salter derav og estere derav som er lett hydrolyserbare in vivo. According to the invention according to Norwegian patent application 78.1970, there is thus provided a method for the production of certain new chemical compounds which are new members of the group of antibiotics known as penicillins, and which are useful as antibacterial agents. These new penicillin compounds are penicillanic acid 1,1-dioxide, pharmaceutically acceptable salts thereof and esters thereof which are readily hydrolyzable in vivo.
Dessuten er penicillansyre-1,1-dioksyd og dets estere som er lett hydrolyserbare in vivo, kraftige inhibitorer for mikrobielle Ø-laktamaser»Furthermore, penicillanic acid 1,1-dioxide and its esters, which are readily hydrolyzable in vivo, are potent inhibitors of microbial Ø-lactamases"

Slik en substituent sies å være i a-konfigurasjon. Omvendt angir heltrukken linje for tilknytning av en substituent til den bicykliske kjerne at substituenten er tilknyttet over kjerne-planet. Denne sistnevnte konfigurasjon omtales som Ø-konfigurasjon. In formula IV, broken line for attachment of a substituent to the bicyclic nucleus indicates that the substituent is below the plane of the bicyclic nucleus. Such a substituent is said to be in a-configuration. Conversely, the solid line for attachment of a substituent to the bicyclic core indicates that the substituent is attached above the plane of the core. This latter configuration is referred to as the Ø configuration.
Når R"*" er en ester-dannende rest som er lett hydrolyserbar in vivo, er den en gruppe som begrepsmessig stammer fra en alkohol med formelen R^-OH slik at andelen COOR^" er av en slik natur at gruppen COOR"<*>" lett spaltes in vivo for å frigi en fri karboksy-gruppe (COOH) . Gruppene R"<*>" er velkjente i penicillin-industrien. I de fleste tilfeller forbedrer de absorpsjons-egenskapene til penicillin-forbindelsen. Dessuten bør R være av en slik natur at den gir farmasøytisk godtagbare egenskaper og at den frigir farmasøytisk godtagbare fragmenter når den spaltes in vivo. When R"*" is an ester-forming residue which is readily hydrolyzable in vivo, it is a group conceptually derived from an alcohol of the formula R^-OH such that the moiety COOR^" is of such a nature that the group COOR"< *>" is easily cleaved in vivo to release a free carboxy group (COOH). The groups R"<*>" are well known in the penicillin industry. In most cases, they improve the absorption properties of the penicillin compound. Moreover, R should be of such a nature that it provides pharmaceutically acceptable properties and that it releases pharmaceutically acceptable fragments when cleaved in vivo.
Som angitt ovenfor er gruppene R^" velkjente og er lette å identifisere for fagfolk i penicillin-industrien. Se for eksemple BRD off. skrift nr. 2.517.316. Typiske R -grupper er 3-ftalidyl, 4-krotonolaktonyl, y-butyrolakton-4-yl og gruppene med formlene As indicated above, the R groups are well known and are easily identified by those skilled in the penicillin industry. See for example BRD Off. Document No. 2,517,316. Typical R groups are 3-phthalidyl, 4-crotonolactonyl, γ-butyrolactone -4-yl and the groups of the formulas

Penicillansyre-la-oksyd, forbindelsen med formel II hvor R<1> er hydrogen, kan fremstilles ved debromering av 6,6-dibrompenicillansyre-la-oksyd. Debromeringen kan utføres ved anvendelse av konvensjonell hydrogenolyseteknikk. Således blir en løsning av 6,6-dibrompenicillansyre-la-oksyd rørt eller ristet under en hydrogen-atmosfære, eller en atmosfære av hydrogen blandet med et inert fortynningsmiddel så som nitrogen eller argon, i nærvær av en katalytisk mengde av palladium-på-kalsiumkarbonat-katalysator. Konvensjonelle løsningsmidler for denne debromering er lavere alkanoler, så som metanol; etere, så som tetrahydrofuran og dioksan; lavmolekylære estere, så som etylacetat og butylacetat; vann; og blandinger av disse løsningsmidler. Det er imidlertid vanlig å velge forhold hvorunder dibromforbindelsen er løselig. Hydrogeno-lysen blir vanligvis utført ved romtemperatur og ved et trykk fra ca. atmosfæretrykk til ca. 3,4 kg/cm 2. Katalysatoren er vanligvis til stede i en mengde på fra ca. 10 vekt%, basert på dibromforbindelsen, opptil en mengde som er lik i vekt med dibromforbindelsen, selv om det kan anvendes større mengder. Omset-ningen varer vanligvis i ca. én time, hvoretter forbindelsen med formel II hvor R"*" er hydrogen, utvinnes ved enkel filtrering fulgt av fjerning av løsningsmidlet i vakuum. Penicillanic acid 1a-oxide, the compound of formula II where R<1> is hydrogen, can be prepared by debromination of 6,6-dibromopenicillanic acid 1a-oxide. The debromination can be carried out using conventional hydrogenolysis techniques. Thus, a solution of 6,6-dibromopenicillanic acid 1a-oxide is stirred or shaken under a hydrogen atmosphere, or an atmosphere of hydrogen mixed with an inert diluent such as nitrogen or argon, in the presence of a catalytic amount of palladium-on- calcium carbonate catalyst. Conventional solvents for this debromination are lower alkanols, such as methanol; ethers, such as tetrahydrofuran and dioxane; low molecular weight esters, such as ethyl acetate and butyl acetate; water; and mixtures of these solvents. However, it is common to choose conditions under which the dibromo compound is soluble. Hydrogenolysis is usually carried out at room temperature and at a pressure of approx. atmospheric pressure to approx. 3.4 kg/cm 2. The catalyst is usually present in an amount of from approx. 10% by weight, based on the dibromo compound, up to an amount equal in weight to the dibromo compound, although larger amounts may be used. The turnover usually lasts for approx. one hour, after which the compound of formula II where R"*" is hydrogen is recovered by simple filtration followed by removal of the solvent in vacuo.

Benzyl- 6, 6- dibrompenicillanat Benzyl- 6, 6- dibromopenicillanate
Til en løsning av 54 g (0,165 mol) 6,6-dibrompenicillansyre i 350 ml N,N-dimetylacetamid ble det satt 22,9 ml (0,165 mol) trietylamin og løsningen ble rørt i 4 0 minutter. Benzylbromid (19,6 ml, 0,165 mol) ble tilsatt, og den resulterende blanding To a solution of 54 g (0.165 mol) of 6,6-dibromopenicillanic acid in 350 ml of N,N-dimethylacetamide was added 22.9 ml (0.165 mol) of triethylamine and the solution was stirred for 40 minutes. Benzyl bromide (19.6 mL, 0.165 mol) was added and the resulting mixt
ble rørt ved romtemperatur i 4 8 timer. Det ut f el te trietylamin-hydrobromid ble frafiltrert, og filtratet ble satt til 1500 ml isvann, justert til pH 2. Blandingen ble ekstrahert med eter, og ekstraktene ble vasket suksessivt med mettet natriumbikarbonat, vann og saltløsning. Den tørkede (MgSO^) eter-løsning ble inndampet i vakuum for å gi et hvitt, fast stoff, som ble omkrystalli-sert fra isopropanol. Dette gav 70,0 g (95% utbytte) av tittel-forbindelsen, sm.p. 75-76°C. IR-spektret (KBr-plate) viste absorpsjoner ved 1795 og 1740 cm<-1>. NMR-spektret (CDCl^) viste absorpsjoner ved 1,53 (s, 3H), 1,58 (s, 3H), 4,50 (s, 1H), 5,13 was stirred at room temperature for 48 hours. The precipitated triethylamine hydrobromide was filtered off, and the filtrate was added to 1500 ml of ice water, adjusted to pH 2. The mixture was extracted with ether, and the extracts were washed successively with saturated sodium bicarbonate, water and brine. The dried (MgSO 4 ) ether solution was evaporated in vacuo to give a white solid, which was recrystallized from isopropanol. This gave 70.0 g (95% yield) of the title compound, m.p. 75-76°C. The IR spectrum (KBr plate) showed absorptions at 1795 and 1740 cm<-1>. The NMR spectrum (CDCl 2 ) showed absorptions at 1.53 (s, 3H), 1.58 (s, 3H), 4.50 (s, 1H), 5.13

Benzyl- 6, 6- dibrompenicillanat- la- oksyd Benzyl- 6, 6- dibromopenicillanate- la- oxide
Til en rørt løsning av 13,4 g (0,03 mol) benzyl-6,6-dibrompenicillanat i 200 ml diklormetan ble det satt en løsning av 6,12 g (0,03 mol) 3-klorperbenzosyre i 100 ml diklormetan, To a stirred solution of 13.4 g (0.03 mol) of benzyl-6,6-dibromopenicillanate in 200 ml of dichloromethane was added a solution of 6.12 g (0.03 mol) of 3-chloroperbenzoic acid in 100 ml of dichloromethane,
ved ca. 0°C. Det ble fortsatt med røring i 1 1/2 time ved ca. 0°C, og reaksjonsblandingen ble filtrert. Filtratet ble vasket suksessivt med 5%ig natriumbikarbonat og vann, og det ble så tørket (Na2S04). Fjerning av løsningsmidlet ved inndamping i vakuum gav 12,5 g av tittel-produktet som en olje. Oljen ble at approx. 0°C. Stirring was continued for 1 1/2 hours at approx. 0°C, and the reaction mixture was filtered. The filtrate was washed successively with 5% sodium bicarbonate and water, and then dried (Na 2 SO 4 ). Removal of the solvent by evaporation in vacuo gave 12.5 g of the title product as an oil. The oil stayed
brakt til fast tilstand ved finfordeling under eter. Filtrering gav så 10,5 g benzyl-6,6-dibrompenicillanat-la-oksyd som et fast stoff. IR-spektret (CDC1,) viste absorpsjoner ved 1800 og 1750 brought to a solid state by fine distribution under ether. Filtration then gave 10.5 g of benzyl-6,6-dibromopenicillanate-1a-oxide as a solid. The IR spectrum (CDC1,) showed absorptions at 1800 and 1750
