Foreliggende oppfinnelse vedrører fremstilling av nye 6,7-disubstituerte 1-cyklopropyl-l,4-dihydro-4-okso-l,8-naftyri-din-3-karboksylsyrer med antibakteriell virkning.
Det er funnet at de ifølge oppfinnelsen fremstilte nye 6,7-disubstituerte 1-cyklopropyl-l,4-dihydro-4-okso-l,8-naftyri-din-karboksylsyrene av formel (I)
hvor
X står for haloaen oa
A står for
spesielt klor, eller fluor, hvor
R<1> står for hydrogen, en alkylgruppe med 1-4 karbonatomer, som evt. kan være subsituert med en hydroksygruppe eller acetyl,
R<2> står for hydrogen, metyl eller fenyl, unntatt forbindelser hvori samtidig X står for fluor og A betyr piperazinyl eller 4-metylpiperazinyl, og deres farmasøytisk anvendelige syreaddisjonssalter, oppviser høy antibakteriell aktivitet.
De egner seg derfor som virksomt stoff for human- og veterinærmedisin, under veterinærmedisin hører også behandling av fisk til terapi eller forebyggelse av bakterielle infeksjoner.
Det er funnet at man får forbindelsene av formel (I) når
man omsetter l-cyklopropyl-7-halogen-l,4-dihydro-4-okso-1,8-naftyridin-3-karboksylsyrene av formel (II)
hvor
X har den ovenfor angitte betydning og
Y står for halogen, fortrinnsvis klor eller fluor, med aminer av formel (III)
hvor
A har den ovenfor angitte betydning (fremgangsmåte aj.
Forbindelsene av formel (I) kan alternativt oppnås ved at man omsetter 1-cyklopropyl-l,4-dihydro-4-okso-7-(1-piperazinyl)-1,8-naftyridin-3-karboksylsyrer av formel (IV)
hvor
X og R 2 har de ovenfor angitte betydninger, med forbindelser av formel (V)
hvor
11
Z er halogen og R er CH^CO-B- hvor B er en alkylgruppe med 1-4 karbonatomer (fremgangsmåte,b).
Ifølge et annet alternativ oppnår man også forbindelsene av formel (I) (R^CH^-CO-CI^CH -) når man omsetter en for-bindelse av formel (IV) med metylvinylketon av formel (VI)
(fremgangsmåte C).
Dersom man ved omsetningen ifølge fremgangsmåte a anvender 2-metyl-piperazin og 7-klor-l-cyklopropyl-6-fluor-1,4-dihydro-4-okso-l,8-naftyridin-3-karboksylsyre som utgangsstoff, så kan reaksjonsforløpet angis ved følgende formel-skj ema:
Anvender man eksempelvis ved omsetningen ifølge fremgangsmåte b kloraceton og 6-klor-l-cyklopropyl-l,4-dihydro-4-okso-7-(1-piperazinyl)-1,8-naftyridin-3-karboksylsyre som utgangsstoffer, så kan reaksjonsforløpet angis ved følgende reaksjonsskjerna:
Dersom man eksempelvis ifølge fremgangsmåte c anvender metylvinylketon og l-cyklopropyl-6-fluor-1,4-dihydro-4-okso-7-(1-piperazinyl)-1,8-naftyridin-3-karboksylsyre som utgangsforbindelser, så kan reaksjonsforløpet gjengis ved følgende
formelskjerna:
De som utgangsstoffer ved fremgangsmåte a anvendte 1-cyklo-propyl-7-halogen-l,4-dihydro-4-okso-l,8-naftyridin-3-karboksylsyrene av formel (II) kan fremstilles i overensstemmelse med følgende reaksjonsskjerna:
Deretter acyleres malonsyredietylester (2) i nærvær av magne-siumetylat med det tilsvarende nikotinsyrehalogenidet (1) til acylmalonester (3) (Organicum, 3 . opplag 1964, s. 438).
Ved partiell forsåpning og dekarboksylering av (3) i vandig medium med katalytiske mengder svovelsyre eller 4-toluen-sulfonsyre får man med godt utbytte acyleddiksyreetylesteren (4), som med ortomaursyre-trietylester/acetanhydrid går over til 2-(nikotinoyl)-3-etoksy-akrylsyreetylester (5). Omsetningen av (5) med cyklopropylamin i et oppløsningsmiddel,
som f.eks. metylenklorid, en alkohol, kloroform, cykloheksan eller toluen fører ved en lett eksoterm reaksjon til det ønskede mellomproduktet (6).
Ringslutningsreaksjonen (6) + (7) gjennomføres i et temperatur-område fra ca. 60 til 300°C, fortrinnsvis 80 til 180°C.
Som fortynningsmiddel kan dioksan, dimetylsulfoksyd, N-metyl-pyrrolidon, sulfolan, heksametylfosforsyretrisamid og fortrinnsvis N,N-dimetylformamid anvendes.
Som syrebindende middel kommer for dette reaksjonstrinnet kalium-tert-butanolat, butyl-litium, litium-fenyl, fenyl-magnesiumbromid, natriummetylat, natriumhydrid, natrium-eller kaliumkarbonat i betraktning. Spesielt foretrukket er kalium- eller natriumfluorid, når hydrogenfluorid må avspal-tes. Det kan være fordelaktig å anvende et overskudd på 10 mol-% av basen.
Esterhydrolysen som foregår i det siste trinnet fra (7) under basiske eller sure betingelser fører til 1-cyklo-propy1-7-halogen-1,4-dihydro-4-okso-l,8-naftyridin-3-karboksylsyrene (II).
Det som utgangsstoff for denne syntesefremgangsmåten anvendte 2,5,6-triklorpyridin-3-karboksylsyrekloridet [Heiv. Chim. Acta 5_9, 222 (1976)] er allerede kjent. 2,6-diklor-5-fluor-pyridin-3-karboksylsyreklorid kan oppnås på følgende måte: 5-amino-2,6-diklor-3-metylpyridin [Heiv. Chim. Acta 5_9, 190 (1976)] overføres via 2,6-diklor-3-metyl-5-(3,3-dimetyl-1- triåzeno)-pyridin eller ved en Baltz-Schiemann-reaksjon til 2,6-diklor-5-fluor-3-metyl-pyridin. Dette kloreres til 2,6-diklor-5-fluor-3-triklormetyl-pyridin. Ved etter-følgende hydrolyse med svovelsyre får man karboksylsyren, som på vanlig måte omvandles til 2,6-diklor-5-fluor-pyridin-3-karboksylsyreklorid. Alternativt til dette kan man også overføre 5-fluor-2,6-dihydroksy-pyridin-3-karboksamid [J. Amer. Chem. Soc. 101, 4423 (1979); J. Org. Chem. 46, 846 (1981)] med fosforoksyklorid til 2,6-diklor-5-fluor-pyridin-3-karbonitril og omsetter dette etter forsåpning til karboksylsyre til syreklorid. Ved oksydasjon av 2,6-diklor-3-klor-metyl-5-nitro-pyridin [Heiv. Chim. Acta 59, 190 (1976)] får man den tilsvarende nikotinsyren som sammen med tionylklorid gir 2,6-diklor-5-nitro-pyridin-3-karboksylsyreklorid.
De som utgangsstoffer anvendte aminene av formel (III) er kjente [US-PS 4 . 166 . 180, J.- Med. Chem. 2_6, 1116 (1983 )]. Som eksempler kan nevnes: piperazin, N-metylpiperazin, N-etylpiperazin, N-(2-hydroksyetyl)-piperazin, N-(2-metoksy-etyl)-piperazin, N-propylpiperazin, N-isopropyl-piperazin, N-butylpiperazin, N-(sek-butyl)-piperazin, N-formylpiperazin, 2- metylpiperaz.in, 2-fenylpiperazin, pyrrolidin.
De som utgangsstoffer anvendte forbindelsene av formel (V) er kjente.
Omsetningen av (II) med (III) ifølge fremgangsmåte a foretas fortrinnsvis i et fortynningsmiddel som dimetylsulfoksyd, N,N-dimetylformamid, heksametyl-fosforsyretriamid, sulfolan, vann, en alkohol som metanol, etanol, n-propanol, isopropanol, glykolmonometyleter eller pyridin. Videre kan blandinger av disse fortynningsmidlene anvendes.
Som syrebindende middel kan alle vanlige uorganiske og organiske syrebindende midler anvendes. Herunder hører fortrinnsvis alkalihydroksydene, alkalikarbonatene, organiske aminer og amidiner. Som spesielt egnede skal særskilt nevnes: trietylamin, 1,4-diaza-bicyklo [2,2,2]-oktan (DABCO), l,8-diaza-bicyklo[5,4,0]-undec-7-en (DBU) eller overskudd amin (III) .
Reaksjonstemperaturen kan varieres innenfor et stort område. Generelt arbeider man mellom ca. 20 og 200°C, fortrinnsvis \ mellom 80 og 18C°C.
Omsetningen kan gjennomføres ved normaltrykk, men også ved forhøyet trykk. Generelt arbeider man ved trykk mellom ca. 1 og ca. 100 bar, fortrinnsvis mellom 1 og 10 bar.
Ved gjennomføringen av fremgangsmåten ifølge oppfinnelsen anvender man til 1 mol karboksylsyre (II) 1-15 mol, fortrinnsvis 1-6 mol av aminet (III).
Frie aminogrupper kan beskyttes under omsetningen ved hjelp av en egnet aminobeskyttelsesgruppe, f.eks. t-butoksykar-bonyl-, etoksykarbonyl- eller acetylgruppe, og etter av-slutning av reaksjonen igjen settes fri. En aromatisk aminogruppe overføres ved reduksjonen til en nitrogruppe.
Omsetningen av (IV) med (V) foretas fortrinnsvis i et fortynningsmiddel som dimetylsulfoksyd, dioksan, N,N-dimetylformamid, heksametyl-fosforsyre-trisamid, sulfolan, vann, en alkohol som metanol, etanol, n-propanol, isopropanol, glykolmonometyleter eller pyridin. Videre kan blandinger av disse fortynningsmidlene anvendes. Som syrebindende middel kan alle vanlige uorganiske og organiske syrebindende midler anvendes. Herunder hører fortrinnsvis alkalihydroksydene, alkalikarbonatene, organiske aminer og amidiner. Som spesielt egnede skal følgende særskilt nevnes: trietylamin, 1,4-diazabicyklo[2,2,2]oktan (DABCO) eller 1,8-diazabicyklo[5,4,0]undec 7-en (DBU).
Reaksjonstemperaturen kan varieres innen et vidt område. Generelt arbeider man mellom 20 og 180°C, fortrinnsvis mellom 40 og 110°C.
Omsetningen kan gjennomføres ved normaltrykk, men også ved forhøyet trykk. Generelt arbeider man ved trykk mellom 1 og 100 bar, fortrinnsvis mellom 1 og 10 bar..
Ved gjennomføringen av fremgangsmåten" i overensstemmelse med fremgangsmåte b ifølge oppfinnelsen, anvender man til 1 mol av forbindelsen (IV) 1-4 mol, fortrinnsvis 1-1,5 mol av forbindelsen (V) .
Omsetningen av (IV) med (VI) (fremgangsmåtec) gjennomføres fortrinnsvis i et fortynningsmiddel som dioksan, dimetyl-sulf oksyd, N,N-dimetylformamid, metanol, etanol, isopropanol, n-propanol, glykolmonometyleter eller også i blandinger av disse fortynningsmidlene.
Reaksjonstemperaturen kan varieres innen et vidt område. Generelt arbeider man mellom ca. 20°C og ca. 150°C, fortrinnsvis mellom 50°C og 100°C.
Omsetningen kan gjennomføres ved normaltrykk, men også ved forhøyet trykk. Generelt arbeider man ved trykk mellom ca. 1 og ca. 100 bar, fortrinnsvis mellom 1 og 10 bar.
Ved gjennomføringen av fremgangsmåten ifølge oppfinnelsen i overensstemmelse med fremgangsmåte c anvender man til 1 mol av forbindelsen (IV) 1-5 mol, fortrinnsvis 1-2 mol, av forbindelsen (VI).
Fremstillingen av syreaddisjonssaltene av forbindelsene av formel I foregår på vanlig måte f.eks. ved oppløsning av betainet i et overskudd av vandig syre og utfelling av saltet med et med vann blandbart organisk oppløsningsmiddel (metanol, etanol, aceton, acetonitril). Man kan også oppvarme ekvivalente mengder betain og syre i vann inntil man oppnår oppløsning og deretter inndampe til tørrhet. Som farmasøy-tisk anvendbare salter forstås eksempelvis saltene av saltsyre, svovelsyre, eddiksyre, glykolsyre, melkesyre, ravsyre, sitronsyre, vinsyre, metansulfonsyre, galakturonsyre, glukon-syre, glutaminsyre eller asparaginsyre.
