Description
Den foreliggende oppfinnelse vedrører en ny type ampicillin som har forbedret vannoppløselighet og større anvendelse som antibiotikum, samt fremgangsmåte til fremstilling av denne forbindelse som vil bli betegnet som metampicillin-lysinat. The present invention relates to a new type of ampicillin which has improved water solubility and greater use as an antibiotic, as well as a method for the production of this compound which will be designated as metampicillin lysinate.
Penicillin-G, slik det forelå da det først ble oppdaget, hadde den ulempe at det var kjemisk ustabilt, noe som innvirket på dets aktivitet og videre at dets bruk som et antibiotikum var begrenset til grampositive bakterier. Den senere oppdagelse av ampicillin som kunne fås fra\6jjjaminopenicillanj3yre^ (penicil-lanic acid), skaffet et antibiotikum som også var effektivt mot i3Ef^?5-~™- bakterier. Penicillin-G, as it existed when it was first discovered, had the disadvantage that it was chemically unstable, which affected its activity and further that its use as an antibiotic was limited to Gram-positive bacteria. The later discovery of ampicillin which could be obtained from \6jjjjaminopenicillanj3yre^ (penicil-lanic acid), provided an antibiotic which was also effective against i3Ef^?5-~™- bacteria.
Uheldigvis oppviser begge disse typer penicillin fortsatt noen av de samme skadelige bivirkninger som naturlig penicillin, Unfortunately, both of these types of penicillin still exhibit some of the same harmful side effects as natural penicillin,
og de har dessuten lav oppløsélighet i vann. Således er oppløse-ligheten av ampicillin eller metampicillin relativt lav, og denne lave oppløsélighet har en ugunstig innvirkning på anti-biotikumets absorpsjon i mage- og tarmsystemet. and they also have low solubility in water. Thus, the solubility of ampicillin or metampicillin is relatively low, and this low solubility has an unfavorable effect on the antibiotic's absorption in the stomach and intestinal system.
Det er derfor en hensikt med den foreliggende oppfinnelse,It is therefore an object of the present invention,
å skaffe en ny type ampicillin med en vesentlig større vannopp-løselighet og stabilitet enn noen av de tidligere kjente ampi-cilliner og metampicilliner. to obtain a new type of ampicillin with a significantly greater water solubility and stability than some of the previously known ampicillins and meta-ampicillins.
Ifølge den foreliggende oppfinnelse er det funnet at enAccording to the present invention, it has been found that a
ny type metampicillin som nu skal beskrives og som kan betegnes som metampicillin-<ly>f<in>^<t>], har en vannoppløselighet som er 2,1 ganger høyere enn vannoppløseligheten av ampicillin-trihydrat. Forbindelsen ifølge oppfinnelsen har således den fordel at den new type of metampicillin which is now to be described and which can be designated as metampicillin-<ly>f<in>^<t>], has a water solubility which is 2.1 times higher than the water solubility of ampicillin trihydrate. The compound according to the invention thus has the advantage that it
kan foreligge lett tilgjengelig i flytende form og dessuten absorberes i mage- og tarmsystemet. can be readily available in liquid form and is also absorbed in the stomach and intestinal system.
Forbindelsen er et derivat av metylen ampicillin hvor 5 ' amino-5'karboksylPentyl-aminometyl radikalet er substituert i The compound is a derivative of methylene ampicillin where the 5' amino-5'carboxylPentyl-aminomethyl radical is substituted in

forbindelse er D- (-) -6- FlO-.(N-5 1 amino-5 'karboksyl^pentylramino-metyl)-aminofenyl-acetamid -3,3-dimetyl-7-okso-4-tio-l-azabicykloheptan-2 karboksylsyre-trihydrat, men den er gitt navnet ampicillin-metylenlysinat eller metampicillin-lysinat fordi L-lysin er bundet til metylenaminoLenzylrpenicillansyre. compound is D-(-)-6- FlO-.(N-5 1 amino-5 'carboxyl^pentylramino-methyl)-aminophenyl-acetamide -3,3-dimethyl-7-oxo-4-thio-1-azabicycloheptane -2 carboxylic acid trihydrate, but it is given the name ampicillin methylene lysinate or metampicillin lysinate because L-lysine is bound to methyleneaminoLenzylperpenicillanic acid.
Metampicillin-lysinat fremstilles syntetisk ved en fremgangsmåte som består av flere trinn. I det første trinn omsettes1 formaldehyd med ampicillin, hvilket gir metylolampi-.; ' Metampicillin lysinate is produced synthetically by a process consisting of several steps.

av natriumkarbonat eller natriumbikarbonat ved en temperatur på 7-10°C og en pH-verdi på 7,0 - 8,0, idet en ampicillin-konsentrasjon på 0,01 mol og en natriumbikarbonat-konsentrasjon på 0,01 mol benyttes. Etter at ampicillinet er blitt gjort vannoppløsélig, lar man en 37-40 prosents formaldehyd-oppløs-ning reagere med ampicillinet i en ca. 2-10 N formalinoppløs-ning, da konsentrasjonen påvirker utbyttet. of sodium carbonate or sodium bicarbonate at a temperature of 7-10°C and a pH value of 7.0 - 8.0, using an ampicillin concentration of 0.01 mol and a sodium bicarbonate concentration of 0.01 mol. After the ampicillin has been made water-soluble, a 37-40 percent formaldehyde solution is allowed to react with the ampicillin for approx. 2-10 N formalin solution, as the concentration affects the yield.
Det neste trinn i fremgangsmåten består i å omsette L-lysin som er en aminosyre, med det mellomprodukt som frem-kommer i det første trinn, og resultatet er metampicillin-lysinat, som er sluttproduktet av syntesen. The next step in the method consists of reacting L-lysine, which is an amino acid, with the intermediate product that appears in the first step, and the result is metampicillin lysinate, which is the final product of the synthesis.
Nedenfor er de kjemiske formler og fremgangsmåter som inngår i reaksjonen vist. Below are the chemical formulas and methods involved in the reaction shown.
EKSEMPEL A EXAMPLE A
En suspensjon av ampicillin (19,5 0 g) i vann (10 00 ml) ble avkjølt til 5°C, langsomt omrørt i 30 minutter for å gi en homogen oppslemning og en pH-verdi på 7-8 frembragt ved tilsetning av en 10% ■ s natriumbikarbona.t-oppløsning (51 ml) . A suspension of ampicillin (19.50 g) in water (1000 ml) was cooled to 5°C, slowly stirred for 30 minutes to give a homogeneous slurry and a pH of 7-8 produced by the addition of a 10% sodium bicarbonate solution (51 ml).
En blanding av denne oppløsning og formalin.(5,8 ml) inneholdende mer enn 37 prosent formaldehyd ble omrørt i 1 time. Deretter ble L-lysin (8,05 g) tilsatt under omrøring som pågikk i 1 time og oppløsningen gjort sur ved tilsetning av saltsyre (7,0 ml) for å gi en pH-verdi på 2,5 - 3,0. En hvit krystallinsk utfelling av metampicillin-L-lysinat fremkom. Etter at blandingen hadde fått stå ved 0°C i 24 timer, ble utfellingen filtrert fra, vasket med tørt aceton og så tørket ved en temperatur på under 40°C. Dette ga et utbytte på 54,9% av et hvitt pulver med et smeltepunkt på 197°-198°C (nedbrytes). A mixture of this solution and formalin (5.8 ml) containing more than 37 percent formaldehyde was stirred for 1 hour. Then L-lysine (8.05 g) was added with stirring for 1 hour and the solution acidified by the addition of hydrochloric acid (7.0 ml) to give a pH value of 2.5 - 3.0. A white crystalline precipitate of metampicillin-L-lysinate appeared. After the mixture had been allowed to stand at 0°C for 24 hours, the precipitate was filtered off, washed with dry acetone and then dried at a temperature below 40°C. This gave a yield of 54.9% of a white powder with a melting point of 197°-198°C (decomposes).
Metampicillin-L-lysinatet produsert ved den foreliggende oppfinnelse er oppløselig i vann, men uoppløselig i etanol ogv! kloroform. Oppløseligheten i eddiksyre er 25 mg/ml og i dimetylformamid 8 mg/ml. The metampicillin-L-lysinate produced by the present invention is soluble in water, but insoluble in ethanol etc! chloroform. The solubility in acetic acid is 25 mg/ml and in dimethylformamide 8 mg/ml.
