Opfindelsen angår også et farmaceutisk præparat, 20 som omfatter en antibakteriel effektiv mængde af en forbindelse med formlen I eller farmaceutisk acceptable salte deraf sammen med en farmaceutisk acceptabel bærer.
Forbindelserne ifølge opfindelsen med formlerne I kan nemt fremstilles ved behandling af en tilsvarende 25 forbindelse med formlen IV med den ønskede cykliske amin VI, Via, vid, Vie eller vif. Til denne reaktion kan en eventuel alkylaminsubstituent, om ønsket, være beskyttet med en gruppe, som gør den i det væsentlige indifferent under reaktionsbetingelserne. F.eks. kan de følgende 30 beskyttelsesgrupper anvendes:
Carboxyl-acylgrupper, såsom formyl, acetyl, trifluorace-tyl; alkoxycarbonylgrupper, såsom ethoxycarbonyl, t-butoxycarbonyl, β,β,β-trichlorethoxycarbonyl, β-iodeth- 35 7 DK 172796 B1 oxycarbonyl; aryloxycarbonylgrupper, såsom benzyloxy-carbonyl, p-methoxybenzyloxycarbonyl, phenoxycarbonyl; silylgrupper, såsom trimethylsilyl; og grupper såsom trityl, tetrahydropyranyl, vinyloxycarbonyl, o-nitrophe-5 nylsulfenyl, diphenylphosphinyl, p-toluensulfonyl og benzyl. Beskyttelsesgruppen kan, om ønsket, fjernes efter reaktionen ved for fagmanden kendte fremgangsmå der. For eksempel kan ethoxycarbonylgruppen fjernes ved sur eller basisk hydrolyse, og tritylgruppen kan fjernes 10 ved hydrogenolyse.
Reaktionen mellem forbindelserne med formlen IV og en egnet beskyttet forbindelse med formlen VI, Via, vid, Vie eller Vif kan udføres med eller uden opløsningsmiddel, fortrinsvis ved forhøjet temperatur i en 15 sådan tid, at reaktionen er i det væsentlige fuldstændig. Reaktionen udføres fortrinsvis i nærværelse af en syreacceptor, såsom et alkalimetal- eller jordalkalime-talcarbonat eller -bicarbonat, en tertiær amin, såsom triethylamin, l,8-diazabicyclo[5,4,0]undec-7-en (DBU), 20 pyridin eller picolin. Alternativt kan et overskud af en forbindelse med en af formlerne VI, Via, Vid, vie eller vif anvendes som syreacceptor.
Egnede opløsningsmidler for denne reaktion er ik-ke-reagerende opløsningsmidler, såsom acetonitril, te-25 trahydrofuran, ethanol, chloroform, dimethylsulfoxId, dimethylformamid, pyridin, picolin, vand og lignende. Opløsningsmiddelblandinger kan også anvendes.
Egnede reaktionstemperaturer er i området fra ca.
20* til ca. 150*C; ved højere temperaturer kræves sæd-30 vanligvis kortere reaktionstid.
Fjernelse af beskyttelsesgruppen kan udføres enten før eller efter Isolering af produktet I eller la. Alternativt behøver beskyttelsesgruppen ikke at fjernes.

Forbindelserne ifølge opfindelsen kan danne farmaceutisk acceptable syreadditions- og/eller basesalte.
Basesaltene dannes med metaller eller aminer, såsom alkali- og jordalkalimetaller eller organiske aminer.
5 Eksempler på metaller, der kan anvendes som kationer, er natrium, kalium, magnesium, calcium og lignende. Eksempler på egnede aminer er N,N'-dibenzylethylendiamin, chlorprocain, cholin, diethanolamin, ethylendiamin, N-methylglucamln og procain.
10 Farmaceutisk acceptable syreadditionssalte dannes med organiske og uorganiske syrer.
Eksempler på egnede syrer til saltdannelse er saltsyre, svovlsyre, phosphorsyre, eddikesyre, citronsyre, oxalsyre, malonsyre, salicylsyre, æblesyre, glucon-15 syre, fumarsyre, ravsyre, ascorbinsyre, maleinsyre, me-thansulfonsyre og lignende. Saltene fremstilles ved at bringe den frie base i kontakt med en tilstrækkelig mængde af den ønskede syre til opnåelse af enten et mono- eller di- osv. salt på sædvanlig måde. De frie 20 baser kan gendannes ved behandling af saltet med en base. For eksempel kan anvendes fortyndede opløsninger af vandig base. Fortyndede vandige natriumhydroxid-, kali-umcarbonat-, ammoniak- og natriumbicarbonatopløsninger er egnede til dette formål. De frie baser afviger en 25 del fra deres tilsvarende saltformer hvad angår fysiske egenskaber, såsom opløselighed i polære opløsningsmidler, men saltene svarer iøvrigt til de tilsvarende frie baser hvad angår deres formål. Ved anvendelse af overskud af base, når R' betegner hydrogen, opnås det til-30 svarende basiske salt.
Forbindelserne ifølge opfindelsen kan forekomme i usolvaterede eller i solvaterede former, omfattende hy-dratiserede former. Sædvanligvis svarer de solvaterede 15 DK 172796 B1 former, indbefattet hydratiserede former og lignende, til de usolvaterede former hvad angår formål.
De i forbindelserne ifølge opfindelsen indgående alkylgrupper udgøres af ligekædede eller forgrenede car-5 bonkæder med fra et til ca. tre carbonatomer, bortset fra når det specielt er angivet, at de indeholder mere end tre carbonatomer. Repræsentative eksempler på sådanne grupper er methyl, ethyl, propyl, isopropyl og lignende.
10 Udtrykket halogen skal betegne fluor, chlor, brom eller iod, med mindre andet er angivet.
Visse forbindelser ifølge opfindelsen kan forekomme i optisk aktive former. Den rene D-lsomer, den rene L-isomer samt blandinger deraf, Indbefattet racemi-15 ske blandinger, er omfattet af opfindelsen. Yderligere asymmetriske carbonatomer kan være til stede i en substituent såsom en alkylgruppe. Alle sådanne isomere samt blandinger deraf er omfattet af opfindelsen.
Forbindelserne ifølge opfindelsen kan fremstilles 20 og administreres i form af mange forskellige orale og parenterale doseringsformer. Det farmaceutiske præparat kan som aktiv bestanddel indeholde en forbindelse med formlen I eller et farmaceutisk acceptabelt salt af en forbindelse med formlen I.
25 Til fremstilling af farmaceutiske præparater ud fra forbindelserne ifølge opfindelsen kan anvendes enten faste eller væskeformige indifferente farmaceutisk acceptable bærere. Faste præparater omfatter pulvere, tabletter, dispergerbare granulater, kapsler, cacheter 30 og suppositorier. En fast bærer kan være et eller flere stoffer, der også kan virke som fortyndingsmidler, smagsstoffer, opløseliggørende midler, smøremidler, suspenderingsmidler, bindemidler eller tablet-desintegre- 16 DK 172796 B1 ringsmidler; den kan også være et indkapslingsmateria-le. I pulvere er bæreren et findelt fast stof, der er blandet med findelt aktiv forbindelse. I tabletter blandes den aktive forbindelse med en bærer, som har de nødvendige sammenbindende egenskaber, 1 passende forhold 5 og presses til den ønskede form og størrelse. Pulvere og tabletter indeholder fortrinsvis fra 5 eller 10 til ca. 70% aktiv bestanddel. Egnede faste bærere er magne-slumcarbonat, magnesiumstearat, talkum, sukker, laktose, pektin, dextrin, stivelse, gelatine, tragacanth, methyl-10 cellulose, natriumcsrboxymethylcellulose, lavt smeltende voks, kakaosmør og lignende. Udtrykket "præparat" omfatter formuleringen af aktiv bestanddel med indkapslende materiale som bærer til opnåelse af en kapsel, i hvilken den aktive bestanddel (med eller uden andre bæ-15 rere) er omgivet af bærer, der således er i kontakt med den. Ligeledes er cacheter omfattet. Tabletter, pulvere, cacheter og kapsler kan anvendes som faste doseringsformer egnet til oral administrering.
væskeformige præparater omfatter opløsninger, su-20 spensioner og emulsioner, som eksempel kan nævnes vandeller vand-propylenglycol-opløsninger til parenteral injektion. Sådanne opløsninger fremstilles således, at de er acceptable for biologiske systemer (isotonicitet, pH osv.). væskeformige præparater kan også formuleres i 25 opløsning i vandig polyethylenglycolopløsning. Vandige opløsninger egnet til oral anvendelse kan fremstilles ved opløsning af den aktive bestanddel i vand og tilsætning af egnede farvestoffer, smagsstoffer, stabiliseringsmidler og fortykningsmidler efter ønske. Vandige 30 suspensioner egnet til oral anvendelse kan fremstilles ved dispergerlng af findelt aktiv bestanddel i vand med et viskost materiale, dvs. naturlig eller syntetisk gum- 17 DK 172796 B1 mi, harpikser, methylcellulose, natriumcarboxymethylcel-lulose og andre velkendte suspenderingsmidler.
Fortrinsvis foreligger det farmaceutiske præparat i enhedsdosisform. I en sådan form er præparatet opdelt 5 i enhedsdoser, der indeholder passende mængder aktiv bestanddel. Enhedsdosisformen kan være et indpakket præparat, hvor pakningen indeholder adskilte mængder præparat, f.eks. indpakkede tabletter, kapsler og pulvere i flasker eller ampuller. Enhedsdosisformen kan også være 10 en kapsel, kachet eller tablet som sådan, eller den kan være et passende antal af en hvilken som helst af disse former.
Mængden af aktiv bestanddel i en enhedsdosis-præparat kan varieres eller indstilles fra 1 mg til 100 mg 15 afhængigt af den specielle anvendelse og styrken af den aktive bestanddel.
Til terapeutisk anvendelse som midler til behandling af bakterielle infektioner administreres forbindelserne anvendt ved den farmaceutiske fremgangsmåde ifølge 20 opfindelsen i en begyndelsesdosis på ca. 3 mg til ca. 40 mg pr. kg. dagligt. En dagig dosis fra ca. 6 mg til ca.
14 mg pr. kg. foretrækkes. Doserne kan imidlertid varieres afhængigt af patientens krav, alvoren af den tilstand, der behandles, og den anvendte forbindelse.
25 Bestemmelse af den rigtige dosis i en speciel si tuation foretages af en fagmand. Sædvanligvis startes behandlingen med doser, der er mindre end den optimale dosis af forbindelsen. Derefter forøges dosis gradvis.
Indtil den optimale virkning under omstændighederne op-30 nås. Den totale daglige dosis kan, hvis det ønskes, opdeles og administreres i portioner i løbet af dagen.
Opfindelsen belyses nærmere ved hjælp af de følgende eksempler.

Til 25,2 g (0,117 mol) natrium-2,3,4,5-tetra-10 fluorbenzoat fremstillet som tørt pulver ud fra 2,3,4,5-tetrafluorbenzoesyre [J. Org. Chem. 29, 2381 (1961)] og vandig natriumhydroxid med koncentration til tørhed, blev sat 400 ml tør ether, og suspensionen blev afkølet til 0eC. Der blev langsomt tilsat 25 ml (~ 2,5 ækvivals lenter) oxalylchlorid i 50 ml ether, og blandingen blev henstillet til opnåelse af stuetemperatur, ved hvilken temperatur den blev holdt 1 2,,0 timer. Den blev filtreret og koncentreret til fjernelse af lavt kogende urenheder. Resten blev opløst i 100 ml ether og anbragt 20 i en tilsætningstragt.
I mellemtiden blev 2,9 g (0,119 mol) magnesiumspåner behandlet med 100 ml absolut ethanol og 0,3 ml carbontetrachlorid. Til denne blanding blev sat 18,6 ml (0,12 mol) diethylmalonat i 75 ml ether med en sådan ha-25 stighed, at temperaturen blev holdt lige under tilbagesvalingstemperaturen. Efter afslutning af tilsætningen blev reaktionsblandingen tilbagesvalet i to timer. Det etheriske syrechlorid blev langsomt tilsat ved -20eC.
Efter afslutning af tilsætningen blev reaktionsblandin-30 gen bragt til en temperatur på 0eC o løbet af 18 timer.
Blandingen blev udhældt i fortyndet saltsyre og ekstraheret til dichlormethan, som blev tørret (MgS04) og koncentreret.
