Description
DK 168008 B1
Opfindelsen angår hidtil ukendte pyridin-2,4- og -2,5-dicarboxylsyrediamid-derivater, deres fremstilling og lægemidler indeholdende dem.
Forbindelser, som inhiberer prolin- og lysinhydroxy-5 lasen, bevirker en særdeles selektiv hæmning af collagen-biosyntesen ved påvirkning af de collagenspecifikke hydroxy-leringsreaktioner. Under forløbet af disse hydroxyleres protein-bunden prolin eller lysin ved indvirkning af enzymerne prolin- eller lysinhydroxylase. Såfremt denne reaktion 10 hindres ved inhibitorer, fremkommer der et ikke funktionsdygtigt, underhydroxyleret collagenmolekyle, som fra cellen kun kan afgives til det ekstracellulære rum i ringe mængde.
Det underhydroxylerede collagen kan desuden ikke indbygges i collagenmatriksen og nedbrydes proteolytisk særdeles let.
15 Som følge af disse virkninger forringes den totale mængde af det ekstracellulært udfældede collagen.
Det er kendt, at inhiberingen af prolinhydroxylasen med kendte inhibitorer såsom a, a'-dipyridyl fører til en hæmning af Clg-biosyntesen af makrofager (jfr. W. Muller et 20 al., FEBS Lett. 90 (1978), 218; Immunbiology 155 (1978), 47). Herved bortfalder den klassiske vej til komplementaktivering. Inhibitorer af prolinhydroxylase virker derfor også som immunsuppresive stoffer, f.eks. ved immunkomplekssygdomme.
25 Det er kendt, at prolinhydroxylase hæmmes effektivt ved hjælp af pyridin-2,4- og -2,5-dicarboxylsyre (jfr. K. Mayama et al., Eur. J. Biochem. 138 (1984), 239-245). Disse forbindelser er i cellekulturen imidlertid kun virksomme som hæmmende stoffer i meget høje koncentrationer (jfr. V.
30 Gtinsler et al., Collagen and Rel. Research 3, 71 (1983)).
I DE offentliggørelsesskrift nr. 3.432.094 beskrives pyridin-2,4- og -2,5-dicarboxylsyrediestere med 1-6 C-atomer i esteralkyIdelen som lægemidler til inhibering af prolin-og lysinhydroxylasen.
35 Disse lav-alkylerede diestere har imidlertid den 2 DK 168008 B1 ulempe, at de spaltes for hurtigt i organismen til syrerne og ikke når frem til deres virkningssted i cellen i tilstrækkelig høj koncentration og dermed er mindre egnede til en eventuel indgivelse som lægemidler.
5 På overraskende måde har det vist sig, at de i det følgende nærmere definerede, hidtil ukendte pyridin-2,4- og -2,5-dicarboxylsyrediamid-derivater er udmærkede hæmningsstoffer for collagenbiosyntesen ved dyremodelforsøg, jf. de i det følgende angivne data for repræsentative forbindelser 10 ifølge opfindelsen.
Det egentlige virksomme stof, pyridin-2,4- eller -2,5-dicarboxylsyre, fremkommer først ved hydrolyse af de her omhandlede derivater i cellen. Disse derivater kan på grund af deres højere lipofili og den kendsgerning, at de 15 under transporten på overraskende måde meget langsomt hydrolyseres, transporteres ind i cellerne. Først her frigøres det egentlige virksomme stof, pyridin-2,4- eller -2,5-dicar-boxylsyre.
Den foreliggende opfindelse angår således pyridin- 20 -2,4- og -2,5-dicarboxylsyrediamid-derivater med formlen COX 0 25 I » R-CH-NH-C —(1) 0\ p
30 O-NH-CH-R

o 35 i hvilken R betyder alkyl, phenylalkyl eller indolyl-3-alkyl, og X betyder OH, alkoxy, phenylalkoxy eller NR3R4, hvor R3 og R4 er ens eller forskellige og betyder H, alkyl eller phenylalkyl, idet de nævnte alkyl- og alkoxygrupper har 1-4 C-atomer, samt deres fysiologisk acceptable salte.
40 Foretrukne forbindelser er pyridin-2,4- eller -2,5- 3 DK 168008 B1 dicarboxylsyrediamid-derivater med formlen I, hvori alkyl-og alkoxygrupperne har 1-3 C-atomer.
Endvidere angår opfindelsen en fremgangsmåde til fremstilling af pyridin-2,4- eller -2,5-dicarboxylsyrediamid-5 -derivaterne med formlen (I), hvilken fremgangsmåde er ejendommelig ved, at en forbindelse med formlen 10 0

(11) - .,
II
o 20 i hvilken Y betyder halogen eller hydroxy eller sammen med carbonylgruppen danner en aktiv ester eller et anhydrid, omsættes med en forbindelse med formlen 25
COX
I (III) R-CH-NH2 30 hvori X og R har de ovenfor angivne betydninger, og hvor, hvis X er OH, COX-gruppen eventuelt er beskyttet, og beskyttelsesgruppen efter omsætningen fraspaltes hydrolytisk eller 35 hydrogenolytisk under dannelse af den frie carboxylgruppe, og at en dannet forbindelse eventuelt omdannes til et fysiologisk acceptabelt salt deraf.
Fremstillingen af forbindelser med formlen (I) og fremstillingen af de dertil nødvendige udgangsforbindelser - 40 såfremt de ikke kan fås i handelen - beskrives nærmere neden for.
Som temporære carboxylbeskyttelsesgrupper er esterbe- 4 DK 168008 B1 skyttelsesgrupper egnede, således som de anvendes ved peptidsyntesen (jfr. f.eks. Kontakte Merck, 3.79. side 15 og 19 f f).
Ofte anvendes der methyl-, benzyl- eller tert.-butyl-5 ester. Fraspaltningen sker alt efter beskyttelsesgruppen ved sur eller alkalisk hydrolyse eller ved hydrogenering i nærværelse af en overgangsmetal-katalysator (jfr. Houben-Weyl, Methoden der organischen Chemie, bind E5, side 496-504, fjerde oplag, 1985).
10 Fremstillingen af forbindelserne ifølge opfindelsen lykkes på den simpleste måde ved, at de to komponenter, pyridin-derivatet med formlen (II) og α-aminosyren eller a-aminosyrederivatet med formlen (III), blandes i ækvimolære mængder eller indtil ca. et 5-dobbelt overskud af (III) og 15 omsættes ved temperaturer mellem -30 og 150°C, fortrinsvis ved 20-100°C, indtil reaktionen ophører. Reaktionens afslutning bestemmes ved hjælp af tyndtlagschromatografi (TC-kon-trol). En variant af denne fremgangsmåde består i, at der arbejdes i et egnet opløsningsmiddel, f.eks. diethylether 20 eller dimethoxyethan eller tetrahydrofuran, chlorerede car-bonhydrider, f.eks. methylenchlorid, chloroform, tri- eller tetrachlorethylen, benzen, toluen eller polære opløsningsmidler, f.eks. dimethylformamid, acetone eller dimethylsulfoxid. Også i denne forbindelse kan der anvendes et overskud af a-25 aminosyrederivat med formlen (III), der kan andrage indtil ca. den 5-dobbelte mængde. Reaktionstemperaturerne ligger herved mellem stuetemperatur og opløsningsmidlets kogepunkt, idet særligt foretrukne temperaturer ligger i området fra stuetemperatur til 130°C.
30 Eventuelt kan omsætningen også ske i nærværelse af baser. Som yderligere baser kommer uorganiske syrebindende midler såsom carbonater eller hydrogencarbonater i betragtning, f.eks. natrium- eller kaliumcarbonat eller natrium- eller kaliumhydrogencarbonat, eller orga-35 niske syrebindende midler såsom tertiære aminer, f.eks.
DK 168008 B1 0 5 triethylamin, tributylamin, ethyldiisopropylamin eller heterocycliske aminer, f.eks. N-alkylmorpholin, pyri-din, quinolin eller dialkylaniliner.
Fortrinsvis sker omsætningen af forbindelserne 5 med formlen (II) med α-aminosyrerne eller ot-aminosyre- derivaterne med formlen (III) under tilsætning af et vand- fraspaltende middel, f.eks. et dialkylcarbodiimid, idet alkylgrupperne har 1-8 C-atomer og i tilfælde af C_ „-forbindelserne også kan være forgrenede eller cyc-J—o 10 liske; der anvendes fortrinsvis dicyclohexylcarbodiimid.
En tilsvarende metode er beskrevet i Houben-Weyl, bd. XV/2, side 103-111, Methoden der Organischen Chemie, 4. opl., Georg Thieme Verlag, Stuttgart, 1974.
Eventuelt kan oparbejdningen af produkterne 15 eksempelvis ske ved ekstraktion eller ved chromatografi, f.eks. over kiselgel. Det isolerede produkt kan omkrystalliseres og eventuelt omsættes med en egnet syre til et fysiologisk acceptabelt salt. Som egnede syrer kommer f.eks. følgende i betragtning: mineralsyrer, f.eks.
20 hydrogenchlorid- og hydrogenbromidsyre samt svovl-, phosphor-, salpeter- eller perchlorsyre, eller organiske syrer, f.eks. myre-, eddike-, propion-, rav-, glycol-, mælke-, asble-, vin-, citron-, malein-, fumar-, phenyl-eddike-, benzoe-, methansulfon-, toluensulfon-, oxal-, 25 4-aminobenzoe-, naphthalen-1,5-disulfon- eller ascorbin-syre.
Udgangsforbindelserne med formlen (II) opnås f.eks. ved omsætning af pyridin-2,4- eller -2,5-dicarb-oxylsyre (II, Y = hydroxy) til det tilsvarende pyridin-30 2,4- eller -2,5-dicarboxylsyrehalogenid, fortrinsvis -chlorid (II, Y = halogen) (ifølge i litteraturen kendte metoder, f.eks. Organikum, Organisch Chemisches Grundpraktikum, 15. opl., VEB Deutscher Verlag der Wissenschaften, 1976, s. 595 ff), som derefter omsættes med en egnet alko-35 hol, f.eks. paranitrobenzylalkohol, til den tilsvarende 6 DK 168008 B1 aktivester (II, Y = aktivester). Ligeledes kan pyridin- 2,4- eller -2,5-dicarboxylsyren også til at begynde med under tilsætning af en egnet carboxylsyre eller carboxyl-syreester, f.eks. chlormyresyreethylester, omdannes til 5 et blandet anhydrid (II, Y = anhydrid), som derefter omsættes med α-aminosyrerne eller a-aminosyre-derivaterne til forbindelserne ifølge opfindelsen. En tilsvarende metode er f.eks. beskrevet i Houben-Weyl, Methoden der organischen Chemie, bind XV/2, side 169-183, fjerde op-10 lag, 1974, Georg Thieme Verlag, Stuttgart.
De her omhandlede forbindelser med formlen I har som allerede nævnt værdifulde farmakologiske egenskaber og er især virksomme som hæmmende midler af prolin- og lysin-hydroxylase, som fibrosuppressive og immunsuppressive midler. 15 Aktiviteten af fibrogenasen kan bestemmes i serumet ved radioimmunologisk bestemmelse af det N-ter-minale propeptid af collagenet type III eller af det N- eller C-terminale tværbindingsdomæne af collagenet type IV (7s-collagen eller type-IV-collagen-NC^).
20 Til dette formål er hydroxyprolin-, procollagen- III-peptid-, 7s-collagen- og type-IV-collagen-NC^-koneen-trationerne blevet målt i leveren hos a) ubehandlede rotter (kontrol) b) rotter, som har fået indgivet carbontetrachlorid 25 (CCl^-kontrol) c) rotter, som først har fået indgivet CCl^ og derefter en forbindelse ifølge opfindelsen (denne forsøgsmetode beskrives af Rouiller, C., Experimental Toxic injury of the Liver; i The Liver, C. Rouil-ler, Vol. -2, s. 335-476, New York, Academic Press, 1964).
Den farmakologiske virkning af de her omhandlede forbindelser er blevet bestemt som den procentuelle hæmning af lever-hydroxyprolin- og serum-7S-(IV)-collagensyn-tesen efter oral indgivelse og i sammenligning med kontrol-35 dyr, der kun har fået indgivet carbontetrachlorid (CCI4-kontroller). Resultaterne fremgår af den følgende tabel 1.

Antal dyr pr. behandlingsgruppe: n = 8 25 Lægemidlerne ifølge opfindelsen er ejendommelige ved, at de indeholder en forbindelse med den almene formel I eller et fysiologisk acceptabelt salt deraf sammen med acceptable farmaceutiske bærere. De nævnte forbindelser kan formuleres som lægemidler, f.eks. i form af farmaceutiske 30 præparater, som indeholder disse forbindelser i blanding med en til enteral, perkutan eller parenteral anvendelse egnet farmaceutisk, organisk eller uorganisk bærer, f.eks. vand, gummi arabicum, gelatine, mælkesukker, stivelse, magne-siumstearat, talk, vegetabilske olier, polyalkylenglycoler 35 eller vaseline.
De farmaceutiske præparater kan foreligge i fast form, f.eks. som tabletter, dragées, suppositorier eller kapsler, i halvfast form, f.eks. som salver, eller i flydende form, f.eks. som opløsninger, suspensioner eller 40 emulsioner. De nævnte præparater er eventuelt steriliserede og/eller indeholder hjælpestoffer, f.eks. konserverings-, stabiliserings-, fugte- eller emulgeringsmidler, salte til ændring af det osmotiske tryk eller pufferstof- 0 8 DK 168008 B1 fer. Præparaterne kan også indeholde andre terapeutisk virksomme stoffer.
