Oppfinnelsen angår særlig fremgangsmåter for fremstilling av hittil ukjente bicykliske forbindelser og farmasøytisk akseptable salter derav som har 5-lipoksygenase-inhiberende aktivitet. Forbindelsene kan anvendes i et farmasøytisk preparat.
De omhandlede bicykliske forbindelser og farmasøytisk akseptable salter derav er hittil ukjente og kan betegnes ved følgende generelle formel (I) :
hvor A betegner eller
R<1> betegner fenyl som kan inneholde cyano eller karbamoyl, eller kinolyl, benztiazolyl, pyridyl, eventuelt med lavere alkyl substituert naftalendionyl,

og farmasøytisk akseptable salter derav.
Ifølge den foreliggende oppfinnelse kan hittil ukjente bicykliske forbindelser (I) fremstilles ved forskjellige fremgangsmåter som kan belyses ved de følgende skjemaer: I de ovenfor angitte formler betegner Y en syrerest, og A, R<1>, R<2>, R<3>, X og m har de ovenfor angitte betydninger.
Foretrukne farmasøytiske akseptable salter av den omhandlede forbindelse (I) er konvensjonelle ikke-toksiske salter og kan omfatte et salt med en syre så som et salt med en uorganisk syre (f.eks. hydroklorid, hydrobromid, sulfat, fosfat, etc.), eller et salt med en organisk karboksyl- eller sulfonsyre (f.eks. formiat, acetat, trifluoracetat, maleat, tartrat, metansulfonat, benzensulf onat, p-toluensulf onat, etc).
Foretrukne eksempler samt illustrasjoner av de forskjellige definisjoner som er nevnt i beskrivelsene ovenfor, og som ligger innenfor den foreliggende oppfinnelses rammer, forklares i detaljer i det følgende.
Uttrykket "lavere" betyr 1 til 6 karbonatomer, med mindre annet er angitt.
Foretrukne eksempler på "lavere alkyl" kan omfatte en rest av
et lineært eller forgrenet alkan med 1-6 karbonatomer så som metyl, etyl, propyl, isopropyl, butyl, isobutyl, t-butyl, pentyl, neopentyl, heksyl og lignende.

Fremgangsmåter for fremstilling av den omhandlede forbindelse (I) forklares i detaljer i det følgende.
Fremgangsmåte 1
Denne fremgangsmåte angår fremstilling av forbindelsen (I<a>) . eller et salt derav ved omsetning av forbindelsen (II) eller et
*. salt derav med forbindelsen (III).
Egnede salter av forbindelsene (I<a>) og (II) kan omfatte de samme salter som de som er eksemplifisert som farmasøytisk akseptable salter av forbindelsen (I) i det foregående.
Reaksjonen kan fortrinnsvis utføres i nærvær av en base. En
egnet base kan være en uorganisk base så som et alkali- eller jordalkalimetallhydroksyd (f.eks. natriumhydroksyd, kalium-hydroksyd, kalsiumhydroksyd, etc), et alkalimetallhydrogen-karbonat (f.eks. natriumhydrogenkarbonat, kaliumhydrogenkarbonat, etc), et alkali- eller jordalkalimetallkarbonat (f.eks. natriumkarbonat, kaliumkarbonat, kalsiumkarbonat, etc), et alkalimetallfosfat (f.eks. natriumdihydrogenfosfat, kalium-dihydrogenfosfat, dinatriumhydrogenfosfat, dikaliumhydrogen-fosfat, etc.) eller en organisk base så som et alkalimetall-
alkoksyd (f.eks. natriummetoksyd, kaliumetoksyd, etc), eller aminer (f.eks. trietylamin, pyridin, lutidin, etc).
Reaksjonen utføres vanligvis på konvensjonell måte. For eksempel utføres reaksjonen fortrinnsvis under avkjøling, ved omgivelsestemperatur eller under oppvarmning og i et konvensjonelt oppløsningsmiddel som ikke har en ugunstig virkning på reaksjonen, så som aceton, metanol, etanol, propanol, N,N-dimetylformamid eller en eventuell blanding derav.
Fremgangsmåte 2
Denne fremgangsmåte angår fremstilling av forbindelsen (I<c>) eller et salt derav ved reduksjon av forbindelsen (I<b>) eller et salt derav.
Egnede salter av forbindelsene (I*3) og (I<c>) kan omfatte de samme salter som de som er eksemplifisert som farmasøytisk akseptable salter av forbindelsen (I) i det foregående.
Reduksjonen utføres ved en konvensjonell fremgangsmåte så som en katalytisk reduksjon; en reduksjon under anvendelse av en kombinasjon av et metall så som jern, tinn eller sink og en syre så som en uorganisk syre (saltsyre, svovelsyre eller lignende) eller en organisk syre (eddiksyre eller lignende); en kombinasjon av en legering (f.eks. natriumamalgam, aluminumamalgam, etc), et metall (f.eks., sink, tinn, jern, etc.) eller et salt derav (f.eks., sinkklorid, tinn(II)klorid, jern(III)- eller jern(II)klorid, etc.) og vann, en alkalioppløsning eller en alkohol (f.eks. metanol, etanol, propanol eller butanol); en hydrazinforbindelse (f.eks. fenylhydrazin eller hydrazin); en kombinasjon av titaniumklorid og saltsyre; et alkalimetallbor-hydrid så som natriumborhydrid, og kaliumborhydrid; litiumaluminiumhydrid; diboran, boran; eller en elektrolytisk reduksjon.
Egnede eksempler på katalysatorer til den katalytiske reduksjon er konvensjonell*; katalysatorer.
I denne reduksjonsprosess kan optisk aktive forbindelser som forbindelsen (I<c>) oppnås ved å anvende som reduksjonsmiddel en kombinasjon av ovennevnte reduksjonsmiddel og optisk aktive ligander så som 4-anilin-3-metylamino-l-butanol, 2-amino-l,l-difenyl-3-metylbutan-l-ol og lignende.
Reaksjonsforholdene for denne reduksjon, for eksempel opp-løsningsmidlet, som skal anvendes, og reaksjonstemperaturen, kan eventuelt velges i overenstemmelse med den reduksjonsmetode som skal anvendes. Det foretrekkes normalt å anvende et oppløsnings-middel så som vann, en alkohol så som metanol, etanol og propanol, dioksan, acetonitril, tetrahydrofuran, dimetyl-formamid, pyridin og lignende.
Reaksjonstemperaturen er ikke spesielt begrenset, og reaksjonen utføres vanligvis under avkjøling, ved omgivelsestemperatur eller ved en forhøyet temperatur.
Fremgangsmåte 3
Denne fremgangsmåte angår fremstilling av forbindelsen (I<e>) ved "hydrolyse av forbindelsen (I<d>).
I denne hydrolysereaksjon er alle konvensjonelle fremgangsmåter som anvendes i hydrolysen av "CN"-gruppen til "CONH211 -gruppen anvendelige.
Hydrolysen utføres fortrinnsvis i nærvær av en base eller en syre. Egnede baser kan omfatte de samme baser som de som er eksemplifisert under den foregående fremgangsmåte 1.
Egnede syrer kan omfatte en organisk syre (f.eks. maursyre, eddiksyre, propionsyre, etc.) og en uorganisk syre (f.eks. saltsyre, bromhydrogensyre, svovelsyre, etc).
Hydrolysen utføres særlig ved anvendelse av konsentrert svovelsyre; eddiksyre og BF3; H2O2 og 0H~; tørr saltsyre efterfulgt av H20.
Denne hydrolyse utføres vanligvis i et organisk oppløsnings-middel, vann eller et blandet oppløsningsmiddel derav.
Reaksjonstemperaturen er ikke kritisk, og reaksjonen kan vanligvis utføres ved omgivelsestemperatur eller under oppvarmning eller opphetning omkring oppløsningsmidlets kokepunkt.
Farmasøytisk akseptable salter av forbindelsen (I) kan fremstilles ved en konvensjonell fremgangsmåte, dvs. ved behandling av forbindelsen (I) med en syre. Foretrukne eksempler på syren er de samme syrer som de som er eksemplifisert i forklaringen av farmasøytisk akseptable salter av forbindelsen (I).
Utgangsforbindelsen (III) og dens salt er hittil ukjente, og de kan f.eks. fremstilles ifølge fremgangsmåter som er beskrevet i det følgende, eller på en tilsvarende måte.
Den omhandlede forbindelse (I) omfatter stereoisomerer så som optiske isomerer, som skyldes et asymmetrisk karbonatom i molekylet, og fremstilling av slike isomerer ligger også innenfor denne oppfinnelses rammer.
Den omhandlede forbindelse, den bicykliske forbindelse (I) og farmasøytisk akseptable salter derav fremstilt ifølge oppfinnelsen har 5-lipoksygenase-inhiberende aktivitet (inhiberende aktivitet på SRS-A syntese), og de er anvendelige som anti-allergisk middel eller anti-inflammatorisk middel eller lignende til mennesker og dyr, og de er særlig anvendelige til behandling av astma, psoriasis, hepatitt, pankreatitt, artritt, nefritt, inflammatoriske tarmsykdommer, septisk sjokk, arterio-sklerose, myokardialt infarkt, cerebral vasospasme eller lignende.
For å belyse anvendeligheten av den omhandlede forbindelse (I) er farmakologisk testdata for representative forbindelser av den omhandlede forbindelse (I) vist nedenfor.

Fremstilling av PMN fra rotter
Sprague-Dawley-hannrotter, som veiet 2 50-3 00 g, ble bedøvet med eter, og hver rotte ble injisert intraperitonealt med 20 ml 0,1% glykogen (fra Oyster). Efter 20 timer ble rottene avlivet, og PMN ble oppnådd fra bukhulen ved skylling med 10 ml Dulbeccos PBS (komponenter i g/L : CaCl2 0,1, KH2P04 0,2, MgCl2'6H20 0,1, NaCl 8,0, Na2HP04<*>7H20 2,16; pH 7,4). Skyllevæskene ble filtrert gjennom et nylonullfilter og sentrifugert i 5 min ved 1000 x g. Pelleten ble suspendert i Dulbeccos PBS og sentrifugert i 5 min ved 1000 x g. Pelleten ble igjen suspendert i Dulbeccos PBS, og cellekonsentrasjonen ble innstilt til IO<7> celler/ml med
•Dulbeccos PBS.
PMN- stimulering
Prøver ble oppløst i etanol og dispergert i Dulbeccos PBS for å oppnå en konsentrasjon på 10~<10->10~<5>M. Antibiotikum A23187; kalsiumionophor (Dehring Diagnostics) (i det følgende betegnet som A23187) i DMSO (lOmM) ble fortynnet med Dulbeccos PBS for å oppnå en konsentrasjon på 1 mM. Alikvoter av cellesuspensjonen (1 x IO<7> celler/ml, 0,98 ml) ble ekvilibrert i 30 min ved 37°C. En oppløsning av prøven (10 jjI) ble tilsatt og inkubert i 15 min ved 37°C før tilsetningen av 10 pl av A23187-oppløsningen. Sluttinkubasjonsvolumet på 1 ml inneholdt således ca. lxlO<7 >celler, 10"<10->10~<5>M prøve og 10 jjM A23187. Inkubasjon med A23187 ble fortsatt i 15 min ved 37°C. Reaksjonene ble stanset ved å sette reagensglassene i isbad for å avkjøle dem så hurtig som mulig til 4°C. Reagensglassene ble sentrifugert ved 1500 x g i 5 min ved 4°C, og supernatantene ble dekantert til rør og holdt kaldt før analyse.
Bestemmelse av immunoreaktiv LTC4 ( i- LTC4)
Konsentrasjonen av i-LTC4 i de cellefrie supernatanter fra inkubasjonene ble bestemt ved spesifikk radioimmunoassay. Gjennomsnittsverdiene av i-LTC4 (disse inkubasjoner ble utført to ganger) av hver prøve ble beregnet, og virkningen av prøvene på syntesen av leukotrienene ble angitt som en prosentdel av verdien uten prøvene. Farmasøytiske preparater kan anvendes i konvensjonelle farma-søytiske former så som pulvere, fine granuler, granuler, tabletter, dragéer, mikrokapsler, kapsler, suppositorier, oppløsninger, suspensjoner, emulsjoner, siruper og lignende. Om ønsket kan preparatet inneholde fortynningsmidler eller disintegratorer (f.eks. sukrose, laktose, stivelse, krystallinsk cellulose, lav-substituert hydroksypropylcellulose, syntetisk aluminiumsilikat, etc), bindemidler (f.eks. cellulose, metylcellulose, hydroksypropylcellulose, hydroksypropyl-metylcellulose, polypropylpyrrolidon, polyvinylpyrrolidon, gelatin, gummi arabicum, polyetylenglykol, etc), farvestoffer, søtemidler, smøremidler (f.eks. magnesiumstearat, etc.) eller lignende.
Dosen av preparatet avhenger av pasientens alder, legemsvekt, tilstand, etc, og preparatet administreres normalt oralt på et daglig dosenivå på fra 100 mg til 10 g beregnet som den omhandlede forbindelse (I) eller dens farmasøytisk akseptable salt, fortrinnsvis fra 1 g til 5 g på samme basis, i et intervall på 1 til 3 ganger daglig. Typiske enhetsdoser kan være 50 mg, 100 mg, 200 mg, 500 mg, 1 g og lignende, idet disse imidlertid kun er eksempler som naturligvis ikke er begrensende.
Oppfinnelsen vil i det følgende belyses ytterligere under henvisning til eksemplene.

De samlede organiske faser ble vasket med saltvann (5 ml), tørret over magnesiumsulfat og konsentrert i vakuum. Residuet ble renset ved kolonnekromatografi på silikagel (eluering med 15% etylacetat i heksan) for å oppnå en blekgul sirup. Den resterende sirup ble krystallisert fra metanol for å oppnå (+)- 2,2-dibutyl-5-(2-kinolylmetoksy)-1,2,3,4-tetrahydro-l-naftol (162
mg) som et hvitt, fast stoff.
Ved sammenligning av de to fysiske konstanter ble det bekreftet
at ovennevnte forbindelse er den samme som forbindelsen fremstilt i eksempel 40.
(1) Anti-arteriosklerotisk aktivitet
Fremgangsmåter
Fremkalling av intima-fortykkelse av kaninhalspulsåre:
40 hvite japanske hannkaniner som veiet ca. 2 kg, ble anvendt til undersøkelsen av forbindelsen ifølge eksempel 40. De ble inndelt i 5 grupper, hver med 8 dyr: den ene gruppen ble brukt som kontrollgruppe og de andre 4 grupper som legeraiddeldoserings-grupper. Kaninene ble forsiktig bedøvet for ikke å skade det omkringliggende vev. En polyetylen-mansjett (1,5 cm lang, 2,15 mm i indre diameter, 3,25 mm i ytre diameter) ble anbragt rundt pulsåren. Kaninene ble holdt på standard laboratoriefor og vann ad libitum i 3 uker. Forbindelsen ifølge eksempel 4 0 og bæreren (0,5% vekt/volum metylcellulose i saltoppløsning) ble administrert intramuskulært én gang daglig, idet man startet den dag mansjetten ble anbragt. Ved slutten av den 3. uke ble kaninene heparinisert (500, i.v.), og pulsåren ble fjernet, vasket ren for blod med saltoppløsning, fiksert ved neddypning i 10% formalin og delt i 8 ca. 2 mm lange tverrsegmenter. Segmentene ble innstøpt i parafin og skåret i tverrsnitt.
Disse snitt ble farvet med orcein. Det ble fremstilt ca. 70 tverrsnitt fra hver pulsåre, og disse snitt ble anvendt for kvantifisering av intima-fortykkelsen.
Kvantifisering av intima-fortykkelse (intimafortykkelses-indeks): Arterie-snittene ble undersøkt ved lysmikroskopi, og intima-fortykkelsen ble bedømt som følger: 0 = ingen fortykkelse; 1 = svak hyperplasi i det subendoteliale rom med intimamediaforhold på ca. 1/10; 2 = adskillige cellelag 1 det subendoteliale rom med intimamediaforhold på ca. 1/5 eller deler av det subendoteliale rom med mer hyperplasi; 3 = sterk hyperplasi i hele det subendoteliale rom med intima-mediaf orhold på mer enn 1/3.
Resultater
Som vist i tabell 1 hemmet forbindelsen ifølge eksempel 40, avhengig av dose, mansjett-fremkalt intimafortykkelse. Særlig i doser på 10 mg/kg oppviste forbindelsen ifølge eksempel 4 0 signifikant inhiberende effekt. Intimafortykkelsesindeks ved denne dose var 0,60 ± 0,21, idet verdien var 42,5% av kontroll-verdien (1,41 ± 0,16).
Tabell 1
Virkning av forbindelsen ifølge eksempel 40 på intimafortykkelse fremkalt ved mansjett-behandling: Tall i parentes betegner prosentverdier basert på middelverdien av bærerkontrollgruppen. Resultatet for bærerkontrollgruppen er angitt som middel verdier ± SE (n=8).
** P < 0,01 sammenlignet med bærerkontrollgruppen.
(2) Virkning på eksperimentell pankreatitt hos mus
Virkningen av 5-lipoksygenaseinhibitor, forbindelsen ifølge eksempel 40, ble undersøkt for en dødelig form for pankreatitt, som ble fremkalt ved å fore mus med ehionin-komplettert cholin-manglende for (CDE-for).
Fremgangsmåter
Det ble anvendt 3 uker gamle ICR-hunnmus til dette eksperiment. Alle mus ble foret med standard laboratoriefor før forsøkene. CDE-foret ble derefter gitt i 2 dager, og ble efter denne periode erstattet med standardfor i ytterligere 6 dager.
Forbindelsen ifølge eksempel 40 ble administrert oralt 2 ganger daglig i 4 dager efter at foring med CDE-for var påbegynt.
Resultater
Som det fremgår av tabell 2 forebygget forbindelsen ifølge eksempel 4 0 CDE-fremkalt pankreatitt avhengig av dose. Overlevelsesprosentene for mus, til hvilke forbindelsen ifølge eksempel 40 ble administrert oralt, var 35% og 85% ved doser på henholdsvis 32 og 100 mg/kg, sammenlignet med de ubehandlede mus hvorav bare 15% overlevde.
