Description
DK 157134 B
Opfindelsen angâr en analogifremgangsmâde til fremstil-ling af bestemte 1-(5-chlorpyrid-2-y1)-1-(2,4-dihalogen-phenyl)- 2-(l,2,4-triazol-l-yl)ethanol-forbindelser eller farmaceutisk acceptable syreaddltlonssalte deraf, der er særligt effektive som orale og topiske midler 5 til behandling af svampesygdomme hos mennesker og andre dy r.
EP patentansogning nr. 0046337 angiver en bred klasse af triazolforbindelser med den almene formel
OH
Az- CH2- C-R1 (I) k2 eller stereoisomere deraf, hvori R^ betyder alkyl, cyc- 2 10 loalkyl eller eventuelt substitueret phenyl, R bety der en heterocyclisk gruppe, og Az betyder en 1,2,4-tria-zolylgruppe, samt syreadditionssalte, ethere, estere og metalkomplekser deraf. Az betyder en 1,2,4-triazol-l-ylgruppe eller 1,2,4-triazol-4-ylgruppe.
15 Disse forbindelser angives at hâve fungicid aktivitet, hovedsageligt som plantefungicider, og ogsâ at være plantevækstregulatorer. De angives ogsâ at hâve anti-fungale egenskaber, som er nyttige til behandling af candidiasis og humage dermatophyt-infektioner.
20 Det har nu vist sig, at to bestemte ueksemplificerede forbindelser inden for denne brede klasse har en grad af in vivo antifungal aktivitet, som er langt sterre end af de forbindelser, som er belyst i eksemplerne til EP patentansegning nr. 0046337, og denne overraskende 25 grad af aktivitet giver forbindelserne særlig værdi 2
DK 157134 B
til systemisk behandling af humane svampeinfektioner.
For at nâ til disse forbindelser er det nadvendigt at 1 2 udvælge bestemte værdier for R og R fra det brede omrâde af værdier, som er angivet, og især er det nad-2 5 vendigt for R at vælge en 5-chlorpyrid-2-ylgruppe, en særlig substituentgruppe, som ikke er angivet i den nævnte EP patentansagning.
De ifalge opfindelsen fremstillede chlorpyridylforbindel-ser har formlen
OH
N ^ XN-CH„-C-/ Cl W ΙΛ=/ 10 hvori Ar betyder 2,4-dichlorpheny1 eller 2,4-difluorphe- nyl, eller er farmaceutisk acceptable salte deraf.
Forbindelsen, hvori Ar er 2,4-difluorphenyl, foretræk-kes.
Forbindelserne kan anvendes i farmaceutiske præparater, 15 især præparater til oral indgivning, omfattende en for- bindelse med formlen (II) eller et farmaceutisk accep-tabelt sait deraf sammen med et farmaceutisk accepta-belt fortyndingsmiddel eller bærer.
Forbindelserne med formlen (II) fremstilles ved frem-20 gangsmâden ifalge opfindelsen, som er ejendommelig ved det i krav l's kendetegnende del anfarte.
Fremgangsmâden ifalge opfindelsen og fremstillingen af udgangsforbindelserne for denne belyses i det falgeri-de reaktionsskema, hvori Ar har den tidligere angivne 25 betydning: 3

Reaktionen gennemf0res simpelthen \/ed ferst at omsstte 2-brom-5-chlorpyridin med n-butyllithium i et inert erganisk oplesningsmiddel, f. eks. diethylether, ved lav temperatur, f. eks. -78 °C, og derpâ tilsætte den 5 passende 2-chlor-21,41-dihalogenacetophenon (III). Mel- lemproduktet (IV) isoleres almindeligvis ikke i ren form, men omsættes direkte med triazol og vandfrit kalium-carbonat i dimethy1formamid. Reaktionen fremskyndes ved opvarmning, f. eks. til 80 °C, og efter nogle timer 10 kan det onskede produkt isoleres pâ konventionel mâde og, om ensket, renses yderligere ved krystallisation eller chromatografi.
De ifelge opfindelsen fremstillede forbindelser indeholder et chiralt center, og bâde adskilte og ikke-adskilte 15 former er omfattet af opfindelsen.
Farmaceutisk acceptable salte af forbindelserne med 4
DK 157134 B
formlen (II) inkluderer dem, der dannes ud fra stærke syrer, som danner ikke-toxiske syreadditionssalte, sâsom saltsyre, hydrogenbromidsyre, svovlsyre, salpetersyre, oxalsyre og methansulfonsyre.
5 Saltene kan opnâs ved konventionelle procedurer, f.
eks. ved blanding af oplosninger indeholdende ækvimolæ-re mængder af den frie base og den onskede syre, og det dannede sait opsamles ved filtrering, hvis det er uoploseligt, eller ved afdampning af oplosningsmidlet.
10 Forbindelserne med formlen (II) og deres farmaceutisk acceptable salte er antifungale midler, der er nyttige til bekæmpelse af svampeinfektioner hos dyr, herunder mennesker. F. eks. er de nyttige til behandling af topiske svampeinfektioner hos mennesket, forârsaget af bl.a.
15 arter af Candida, Trichophyton, Microsporum eller Epider- mophyton, eller til behandling af slimhindeinfektioner forârsaget af Candida albicans (f. eks. treske og vaginal candidiasis). de kan ogsâ anvendes systemisk til behandling af systemiske svampeinfektioner forârsaget af f.
20 eks. Candidas albicans, Cryptococcus neoformans, Aspergil- lus fumigatus, Coccidioides, Paracoccidioides, Histo-plasma eller Blastomyces.
In vitro bedommelsen af forbindelsernes antifungale aktivitet kan gennemfares ved bestemmelse af den mini-25 male inhiberende koncentration (MIC) af proveforbindelser- ne i et egnet medium, hvorved der ikke sker vækst af den bestemte mikroorganisme. I praksis podes en rskke agarplader, som hver har proveforbindelsen inkorporeret i en bestemt koncentration, med en standardkultur af 30 f. eks. Candida albicans, og hver plade inkuberes derpâ i 48 timer ved 37 °C. Pladerne undersoges derpâ for forekomst eller fravær af vækst af svampen, og den pâgæl- 5
DK 157134 B
dende MIC-værdi noteres. André mikroorganismer, der kan anvendes ved sâdanne pravninger, er f. eks. Crypto-coccus neoformans, Aspergillus fumigatus, Trichophyton spp, Microsporum spp, Epidermophyton floccosum, Cocci-5 dioides immitis og Torulopsis glabrata.
In vivo bedammelsen af forbindelserne kan udfores ved en række dosisniveauer ved intraperitoneal eller intra-venas injektion eller ved oral indgivning til mus, som har fâet indpodet en stamme af Candida albicans. Akti-10 viteten baseres pa overlevelsen af en behandlet gruppe af mus efter daden af en ubehandlet gruppe af mus efter 48 timers iagttagelse. Det dosisniveau, hvorved farbin-delsen giver 50 % beskyttelse over for infektionens dedelige virkning, noteres. 1 2 3 4 5 6
Resultater opnâet for forbindelserne med formlen (II) 2 ved sâdanne prevninger viser, at de er meget mere effek- 3 tive som orale antifungale midler end de forbindelser, 4 der er angivet i eksemplerne til EP patentansagning 5 nr. 0046337, som det kan ses af den falgende tabel, 6 som giver sammenligningsresultater for to af forbindel- serne fra den nævnte EP ansagning sammen med resultater for forbindelserne fra eksempel 1 og 2 i denne beskri-velse efter oral indgivning til mus inficeret med Candida albicans.

Til human brug kan de ifolge opfindelsen fremstillede antifungale forbindelser indgives alene, men almindelig-vis vil de blive indgivet i blanding med en farmaceu-tisk bærer udvalgt med henblik pâ den pâtænkte indgiv-5 ningsvej og farmaceutisk standardpraksis. F. eks. kan 7

de indgives oralt i form af tabletter indeholdende sâdan-ne excipienter som stivelse eller lactose, eller i kapsler eller æg enten alene eller i blanding med excipienter, eller i form af en sirup eller suspension indeholdende 5 aroma- eller farvemidler. De kan injiceres parenteralt, f. eks. intravenest, intramuskulært eller subcutant,
Til parentéral indgivning anvendes de bedst i form af en steril vandig oplasning, som kan indeholde andre stoffer, f. eks. tilstrækkeligt salte eller glucose 10 til at gare oplasningen isotonisk med blod.
Til oral og parentéral indgivning hos humane patienter forventes det, at det daglige doseringsniveau af de omhandlede antifungale forbindelser vil være 0,1 - 10 mg/kg (i opdelte doser), nâr de indgives ad enten den 15 orale eller den parenterale vej. Sâledes kan tabletter eller kapsler med forbindelserne forventes at indeholde fra 5 mg til 0,5 g aktiv forbindelse til indgivning alene eller to eller flere ad gangen efter behov. I hvert tilfælde vil lægen bestemme den faktiske dosering, 20 som vil være mest egnet for en individuel patient, og den vil variere med den bestemte patients aider, vægt og reaktion. De ovennævnte doseringer er eksempler pâ gennemsnitstilfælde, men der kan selvfalgelig være individuelle tilfælde, hvor hajere eller lavere doserings-25 omrâder kan være af værdi.
Alternativt kan de ifalge opfindelsen fremstillede antifungale forbindelser med formlen (II) indgives i form af et suppositorium eller pessar, eller de kan pâferes topisk i form af en lotion, oplesning, creme, salve 30 eller et pudder. F. eks. kan de inkorporeres i en creme bestâende af en vandig émulsion af polyethylenglycoler eller flydende paraffin; eller de kan inkorporeres i en koncentration mellem 1 og 10 % i en salve bestâende 8

af en hvid voks eller hvid blad paraffinbase sammen med sâdanne stabiliseringsmidler og konserveringsmidler som mâtte være nadvendige.
De falgende eksempler tjener til nærmere belysning af 5 fremgangsmâden ifalge opfindelsen.
