Description
Foreliggende oppfinnelse angår hittil ukjente cefalosporan7syrederivater som kan anvendes som utgangsmateriale for fremstilling av nye antibakterielt aktive cefalosporansyredérivater med den generelle formel I
hvor
R er acyl,
R 2 er en amino-lavere-alkyl-, lavere alkanoylamino-lavere-alkyl-,
lavere alkoksykarbonylamino-lavere-alkyl-, lavere alkan-sulfonylamino-lavere-alkyl-, lavere alkoksykarbonylamino-lavere-alkanoylamino-lavere-alkyl-, lavere alkylureido-lavere-alkyl-, guanidino-karbonylamino-lavere-alkyl- eller hydroksy-lavere-alkyl-substituert tiadiazolyl- eller tetrazolylgruppe, og
M er et hydrogenatom eller et ugiftig, farmasøytisk godtagbart kation^.
Betegnelsen "acyl", som er angitt som betydningen av R , betyr særlig en lavere alkanoylgruppe som er substituert med en lavere alkyltiogruppe, en fenylgruppe eller en lavere alkyl-substituert oksadiazolyl-, tienyl- eller tetrazolylgruppe,
idet alkyldelen av den lavere alkanoylgruppe kan være ytterligere substituert med en hydroksygruppe, en aminogruppe eller en lavere alkoksykarbonylaminogruppe,
"Amino-lavere-alkyl", som er en substituent i tiadiazolyl-eller .tetrazolylgruppen, er f;eks. aminometyl, 1-aminoetyl, 2-aminoetyl, 1-aminopropyl, 2-aminopropyl, 3-aminopropy1, 1-aminobutyl, 2-aminobutyl, 3-aminobutyl, 4-aminobuty1, 5-amino-pentyl, 6-aminoheksyl, 2-aminoisopropyl og 3-aminoisobutyl.
Andre substituenter er f.eks. en alkoksykarbonyl-substituert aminoalkylgruppe, hvor alkoksykarbonylgruppen kan være metoksykarbonyl, etoksykarbonyl, propoksykarbonyl, isopropoksykarbonyl, butoksykarbonyl, isobutoksykarbonyl og tért.butoksykarbonyl, en alkansulfonylsubstituert aminoalkyl gruppe, hvor alkansulfonylgruppen kan være metansulfony1, etansulfonyl, propansulfony1, isopropansulfonyl, butansulfonyl, isobutansulfonyl, tert.butansulfonyl, pentansulfonyl og heksan-sulfonyl, en N-alkyl-karbamoylsubstituert aminoalkylgruppe, hvor N-alkylkarbamoylgruppen kan være N-metylkarbamoy1, N-etylkarbamoyl og N-propylkarbamoyl, og en 1-guanidino-karbonylsubstituert aminoalkylgruppe.
"Hydroksy-lavere-alkyl", som er en annen substituent i tiadiazol- eller tetrazolylgruppen, er f.eks. hydroksymetyl, 1-hydroksyetyl, 2-hydroksyetyl, 1-hydroksypropyl, 2-hydroksypropyl, 3-hydroksypropyl, 1-hydroksybutyl, 2-hydroksybutyl, 3-hydroksybutyl, 4-hydroksybutyl, 5-hydroksypentyl, 6-hydroksy-heksyl, 2-hydroksyisopropyl og 3-hydroksyisobutyl.
De nye forbindelser i henhold til oppfinnelsen har den generelle formel
hvor R 2 og M har den ovenfor angitte betydning.
De her omhandlede cefalosporansyredérivater med den generelle formel IV kan fremstilles ved at en 7-substituert cefalosporansyre med den generelle formel II
hvor R^ betegner en alkanoylgruppe og M har den ovenfor angitte betydning, omsettes med en tiolforbindelse med den generelle formel III
hvor R 2hår den ovenfor angitte betydning, eller et alkalimetallsalt derav.
Betegnelsen "alkanoyl", som er angitt i sammenheng med R 3 i formel II, angir f.eks. acetyl, propionyl, butyryl, pentanoyl! og heksanoyl.
Alkalimetallsalter av tiolforbindelsen med den generelle formel III kan f.eks. være natrium- eller kaliumsalter.
Omsetningen av en 7-substituert cefalosporansyre med den generelle formel II med en tiolforbindelse med den generelle formel III eller et alkalimetallsalt derav kan utføres i et opp-løsningsmiddel så som vann, aceton, kloroform, nitrobenzen, dimetylformamid, metanol, etanol, dimétylsulfoksyd eller et hvilket som helst organisk oppløsningsmiddel, som er inert overfor reaksjonen, fortrinnsvis i et sterkt polart oppløsningsmiddel. Det kan som oppløsningsmidler anvendes hydrofile oppløsnings-midler i blanding med vann. Omsetningen utføres fortrinnsvis i omtrentlig nøytralt medium. Når . forbindelsen med den generelle formel II eller tiolforbindelsen med den generelle formel III anvendes i fri form, utføres omsetningen fortrinnsvis i nærvær av en base så som et alkalimetallhydroksyd, alkalimetallkarbonåt, alkalimetallbikarbonat eller et trialkylamin. Reaksjonstemperaturen er ikke begrenset, og omsetningen utføres vanligvis ved romtemperatur eller under oppvarmning. Reaksjonsproduktet kan under anvendelse av konvensjonell fremgangsmåter isoleres fra reaksjonsblandingen.
Når omsetningen utføres under anvendelse av en forbindelse med den generelle formel III, hvor R 2er en amino-lavere-alkyl-substituert tiadiazolyl- eller tetrazolylgruppe, kan de frie aminogrupper beskyttes under anvendelse av konvensjonelle beskyttelsesgrupper. I dette tilfelle kan amino-beskyttelsesgruppen om nødvendig fjernes fra reaksjonsproduktet.
Fjernelsen av aminobeskyttelsesgruppen kan utføres under anvendelse av en konvensjonell fremgangsmåte så som spaltning med syre og katalytisk reduksjon, og fremgangsmåten velges avhengig av arten åv beskyttelsesgruppen på aminogruppen. Spaltningen med syre er. en av de mest egnede fremgangsmåter og kan anvendes til fjernelse av substituenter så som benzyloksykarbonyl, substituert benzyloksykarbonyl, alkoksykarbonyl, substituert alkoksykarbonyl, aralkoksykarbony1, adamantyloksy-karbonyl, trityl, substituert fenyltio, substituert aralkyliden, substituert alkyliden og substituert cykloalkyliden.. Den til den ovenfor angitte omsetning anvendte syre velges avhengig av arten av aminobeskyttelsesgruppen, og egnede syrer er f.eks.I maursyre og trifluoreddiksyre, som lett avdampes under redusert trykk. Når spaltningen med syre utføres i et oppløsningsmiddel, kan det som oppløsningsmiddel anvendes et hydrofilt organisk oppløsningsmiddel, vann eller en blanding derav. Den kata-lytiske reduksjon kan anvendes til fjernelse av amino-beskyttelsesgrupper så som benzyloksykarbonyl, substituert benzyloksykarbonyl og 2-pyridyImetoksykarbony 1. En egnet katalysator er palladium, men det kan også anvendes andre katalysatorer,.som konvensjonelt anvendes til katalytisk reduksjon.
Trifluoracetylgruppen kan fjernes ved behandling av reaksjonsproduktet med vann, og halogensubstituerte alkoksy-karbonylgrupper og 8-kinolyloksykarbonylgrupper kan fjernes ved behandling av reaksjonsproduktet med et tungmetall så som kobber og sink. Fjernelsen av aminobeskyttelsesgruppen kan utføres uten isolering og rensning av reaks jonsproduktet 'fra • reaksjonsmediet.
Forbindelsene med den generelle formel I kan fremstilles ved at en forbindelse med den generelle formel IV eller et derivat derav ved aminogruppen og/eller karboksylgruppen, omsettes med en organisk karboksylsyre med den generelle formel V
