Omsætningen af forbindelsen (II) med forbindelsen 20 (III) gennemføres fortrinsvis i et fortyndingsmiddel, såsom dimethylsulfoxid, Ν,Ν-dimethylformamid, N-methylpyrrolidon, hexamethylphosphorsyretrisamid, sulfolan, acetonitril, vand, en alkohol, såsom methanol, ethanol, n-propanol, isopropanol eller glykolmonomethylether, eller pyridin. Der kan ligeledes 25 anvendes blandinger af disse fortyndingsmidler.
Som syrebinder kan der anvendes alle gængse uorganiske og organiske syrebindemidler. Hertil hører fortrinsvis alka-limetalhydroxiderne, alkalimetalcarbonaterne, organiske aminer og amidiner. Som særligt egnet skal i detaljer nævnes 30 triethylamin, l,4-diazabicyclo[2.2.2]octan (DABCO), 1,8- diazabicyclo[5.4.0]undec-7-en (DBU) eller overskud af amin (III).
Reaktionstemperaturerne kan varieres indenfor et større område. Der arbejdes almindeligvis ved temperaturer 35 mellem ca. 20°C og 200°C, fortrinsvis mellem 80"C og 180°C.
Omsætningen kan gennemføres ved normalt tryk, men DK 170404 B1 10 også ved forhøjet tryk. Almindeligvis arbejdes der ved tryk mellem ca. 1 og 100 bar, fortrinsvis mellem 1 og 10 bar.
Ved gennemførelsen af den her omhandlede fremgangsmåde anvendes der til 1 mol carboxylsyre (II) 1-15 mol, fortrins-5 vis 1-6 mol af forbindelsen (III).
Frie hydroxygrupper kan beskyttes under omsætningen med en egnet hydroxybeskyttelsesgruppe, f.eks. med en tetra-hydropyranylgruppe, og efter endt reaktion igen befries for beskyttelsesgruppen (jf. J.F.W. McOmie, Protective Groups 10 in Organic Chemistry (1973), side 104).
Frie aminofunktioner kan beskyttes under omsætningen med en egnet aminobeskyttelsesgruppe, f.eks. med en ethoxy-carbonyl- eller tert.butoxycarbonylgruppe, og efter endt reaktion igen befries for beskyttelsesgruppen ved behandling 15 med en egnet syre, såsom hydrogenchloridsyre eller trifluor-eddikesyre (jf. Houben-Weyl, Methoden der organischen Che-mie, bind E4, side 144 (1983) og J.F.W. McOmie, Protective Groups in Organic Chemistry (1973), side 43).

Det fremkomne reak-25 tionsvand kan også fjernes ved azeotrop destillation med chloroform, tetrachlormethan, benzen eller toluen.
Fremstillingen af estere kan også med fordel gennemføres ved opvarmning af en til grund liggende syre med dimethyl formamiddialkylacetal i et opløsningsmiddel, såsom dime-30 thylformamid.
Fremstillingen af syreadditionssaltene af de her omhandlede forbindelser sker på gængs måde, f.eks. ved opløsning af betain i overskud af vandig syre og udfældning af saltet med et med vand blandbart organisk opløsningsmiddel, , 35 såsom methanol, ethanol, acetone eller acetonitril. Det er også muligt at opvarme ækvivalente mængder betain og syre i DK 170404 B1 11 vand og en alkohol, såsom glykolmonomethylether, og derefter inddampe til tørhed eller fraskille det udfældede salt ved sugning. Som pharmaceutisk anvendelige salte skal f.eks. forstås saltene af saltsyre, svolvsyre, eddikesyre, glycol-5 syre, mælkesyre, ravsyre, citronsyre, vinsyre, methansulfonsyre, 4-toluensulfonsyre, galacturonsyre, gluconsyre, pomoa-syre, glutaminsyre eller asparaginsyre.
Alkalimetal- eller jordalkalimetalsaltene af de her omhandlede carboxylsyrer fremstilles f.eks. ved opløsning 10 af betain i underskud af alkalimetal- eller jordalkalimetal-hydroxidopløsning, frafiltrering af uopløst betain og ind-dampning af filtratet til tørhed. Pharmaceutisk egnet er natrium kalium- eller calciumsalte. Ved omsætning af et alkalimetal- eller jordalkalimetalsalt med et egnet sølv-15 salt, såsom sølvnitrat, fås de tilsvarende sølvsalte.
Foruden de i eksemplerne nævnte aktive stoffer kan der også fremstilles de i tabel I eksempelvis anførte forbindelser, hvorved disse forbindelser kan foreligge både som diastereomerblandinger og som diastereomerrene eller 20 enantiomerrene forbindelser.

Fremstillingen af de ovenfor anførte pharmaceutiske præparater sker på gængs måde, ifølge kendte metoder, f.eks. ved blanding af de virksomme stoffer med bærestofferne.
25 De nævnte præparater kan hos mennesker og dyr anvendes enten oralt, rektalt, parenteralt (intravenøst, intramus-kulært eller subkutant), intracisternalt, intravaginalt, intraperitonealt, lokalt (puddere, salver, dråber) og til behandling af infektioner i hulrum eller legemshuler. På 30 tale som egnede præparater kommer injektionsopløsninger, opløsninger og suspensioner til oral behandling, geler, infusionsformuleringer, emulsioner, salver eller dråber. Til lokal behandling kan der anvendes ophthalmologiske og dermatologiske formuleringer, sølv- og andre salte, øredrå-35 ber, øjensalver, puddere eller opløsninger. Ved dyr kan DK 170404 B1 21 drikkevandet. Desuden kan der ved mennesker og dyr anvendes geler, pulvere, puddere, tabletter, depottabletter, præblandinger, koncentrater, granulater, pellets, boli, kapsler, aerosoler, sprays og inhalater. Desuden kan de her omhandlede 5 forbindelser indarbejdes i andre bærematerialer, såsom formstoffer (formstofkæder til lokal behandling) kollagen eller knoglecement.
Generelt har det både indenfor human- og veterinærmedicinen vist sig fordelagtigt at indgive de her omhandlede 10 virksomme stoffer i samlede mængder på ca. 0,5 til ca. 500, fortrinsvis 5 til 100 mg/kg legemsvægt pr. døgn, eventuelt i form af flere enkelt indgivelser, til opnåelse af de ønskede resultater. En enkelt indgift indeholder de virksomme stoffer ifølge opfindelsen i mængder på fortrinsvis ca. 1 til ca.
15 80, især 3-30 mg/kg legemsvægt. Det kan dog være nødvendigt at afvige fra de nævnte doseringer afhængig af arten og legemsvægten af det individ, der skal behandles, arten og omfanget af sygdommen, arten af præparatet og applikationen af lægemidlet samt det tidsrum eller interval indenfor hvil-20 ket indgiften sker.
Således kan det i nogle tilfælde være tilstrækkeligt at anvende mindre mængder af virksomt stof end den ovenfor anførte mængde, medens det i andre tilfælde er nødvendigt at overskride den ovenfor anførte mængde af virksomt stof.
25 Fastlæggelsen af den til enhver tid nødvendige optimale dosering og applikationsart af de virksomme stoffer kan let ske af enhver fagmand på grundlag af hans faglige viden.
De her omhandlede forbindelser kan indgives i de gængse koncentrationer og præparater sammen med foderet 30 eller foderpræparaterne eller sammen med drikkevandet. Derved kan man hindre, bedre og/eller hele en infektion forårsaget af gram-negative eller gram-positive bakterier, og derved kan man opnå at fremme væksten og opnå en forbedring af udnyttelsen af foderet.
35 De minimale hæmningskoncentrationer (MHK) bestemmes DK 170404 B1 22 ved rækkefortyndingsmetoder på Iso-sensitest-agar (Oxoid).
Til hver prøvesubstans fremstilles der en række agarplader som ved hver gang dobbelt fortynding indeholder aftagende koncentrationer af det virksomme stof. Agarpladerne podes 5 med en Multipoint-inokulator (Denley). Til podningen anvendes der kulturer af sygdomsvækkeren, opbevaret natten over som forinden er fortyndet således, at hvert podepunkt indeholder ca. 104 kolonidannende partikler. De podede agarplader inkuberes ved 37“C, og kimvæksten aflæses efter ca. 20 timer.
10 MHK-værdien (/xg/ml) angiver den laveste koncentration af virksomt stof, ved hvilken der med det blotte øje ikke kunne konstateres kimvækst.
I den følgende tabel er anført MHK-værdierne for nogle af de her omhandlede forbindelser i sammenligning med 15 ciprofloxacin.
