Description
i DK 168573 B1
Den foreliggende opfindelse angår hidtil ukendte methylendi-phosphonsyrederivater med terapeutiske egenskaber, der muliggør deres anvendelse til behandling af reumatiske lidelser, fremgangsmåder til fremstilling deraf samt farmaceutiske mid-5 ler indeholdende methylendiphosphonsyrederivater.
Nærmere betegnet angår opfindelsen derivater af methylendi-phosphonsyre, hvilke derivater er ejendommelige ved, at de har den almene formel 9 10 <“H2
NH
O i O
HO—P——C-P—OH (X)
HO ^ Alk OH
S
i B1 hvori R-l betegner en phenyl gruppe, der er substitueret med et 15 halogenatom, en methylgruppe eller en trifluormethylgruppe, og Alk betegner en ligekædet C1-Cg-alkylengruppe, samt salte af nævnte derivater med uorganiske eller organiske baser.
Derivaterne med formlen I er i stand til at danne salte med uorganiske eller organiske baser. Disse salte udgør en inte-20 grerende del af opfindelsen. En med forbindelserne med formlen I beslægtet forbindelse har tidligere været beskrevet, men i intet tilfælde har dens terapeutiske egenskaber været nævnt.
Således beskriver tysk patentskrift nr. 2.754.821 forbindelsen 1-amino-l-methylthio-methylen-l, 1-diphosphonsyre. Patentskrif-25 tet omhandler endvidere de tilsvarende alkalisalte og jordal-kalisalte samt forbindelsernes anvendelse som additiver til behandling af vand inden for tekstil- og papirindustrien.
Endvidere beskriver dansk patentansøgning nr. 3367/83 methy-lendiphosphonsyrederivater, der er strukturelt nært beslægtet 30 med forbindelserne med formlen I. De kendte methylendiphos- DK 168573 B1 2 phonsyrederivater har ligesom forbindelserne ifølge den foreliggende opfindelse nyttig antiinflammatorisk og anti-rheumatisk virkning. I forhold til de kendte derivater har forbindelserne med formlen I dog en meget højere virkningsin-5 tensitet.
Den foreliggende opfindelse angår - endvidere en fremgangsmåde til fremstilling af forbindelserne med formlen I.
Fremgangsmåden ifølge opfindelsen er ejendommelig ved, at et amid med formlen 10 R1 - S - Alk - C - NH - CH2 0 hvori og Alk er som defineret ovenfor, sammen med phosphor-syrling og phosphortrichlorid i et indifferent opløsningsmid-15 del opvarmes til en temperatur mellem 50 og 100°C, og at den opnåede syre om ønsket omdannes til et af ovennævnte salte.
Amidet opnås på kendt måde ved at gå ud fra syrerne - S - Alk- COOH, f.eks. ved indvirkning af thionylchlorid eller phosphortrichlorid på syren, efterfulgt af omsætning med ami-20 nen
Det således fremstillede amid opvarmes derpå sammen med phos-25 phorsyrling og phosphortrichlorid i et indifferent opløsningsmiddel, såsom dimethoxyethan, ved en temperatur mellem 50 og 100°C i 2 - 6 timer.
De således opnåede phosphorsyrer kan på kendt måde omdannes til et af saltene deraf. Omdannelsen gennemføres i et varmt 30 opløsningsmiddel, så at salte krystalliserer ved køling efter eventuel tilsætning af et yderligere opløsningsmiddel.
De følgende eksempler anføres til illustration af opfindelsen.
DK 168573 B1 3
Eksempel 1 - ikke ifølge opfindelsen.
Mononatriumsalt af 1-methylamino-4- (4-chlorphenylthio) -butyli-den-1,1-diphosphonsyre (SR 43140 A).
En blanding af 20 g N-methyl-4-(4-chlorphenylthio)-butyramid, 5 10 ml phosphortrichlorid, 13 g phosphorsyrling og 100 ml dime- thoxyethan opvarmes til 83 - 84°C under tilbagesvaling i 3 timer.
Man lader derpå blandingen henstå i 12 timer ved omgivelsernes temperatur og frafiltrerer krystallerne. Man vasker med metha-10 nol og derpå med acetone. Vægt 25 g.
Den således opnåede syre suspenderes i 250 ml vand, hvorpå man tilsætter 15 g natriumacetat og opvarmer i 3 timer under tilbagesvaling.
Efter afkøling frafiltreres det faste stof, som man vasker med 15 methanol og derpå med ether og tørrer. Vægt 24,25 g, smeltepunkt over 260°C.
Grundstofanalyse:
Beregnet: C% 32,09, H% 4,16, N% 3,40.
Fundet: 32,09, 3,85, 3,46.
20 Eksempel 2 - ifølge opfindelsen.
Ved at gå frem som i eksempel 1, men under ændring af udgangs-amidet, opnår man forbindelsen l-benzylamino-4-methylthio-bu tyl iden-1, l-diphosphonsyre (se tabel I). Når syren ikke krystalliserer ved afkøling af reaktionsblandingen, inddamper 25 man til tørhed under vakuum og optager resten i vand.
Til fremstilling af natriumsaltene kan man erstatte natriumacetat med natriumhydroxid.

Forbindelserne ifølge opfindelsen anvendes fordelagtigt som antiinflammatoriske og antireumatiske lægemidler, og deres farmakologiske egenskaber er blevet påvist på følgende måde: "In vivo"-forsøg: Artritis-hjælpestof.
5 Injektion af Mycobacterium i rotter medfører en polyartritis, der i visse henseender minder om human reumatoid artritis.
Forsøgsforskrift..
En suspension af Mycobacterium tuberculosis (0,4 mg) i paraffinolie (0,05 ml) injiceres ad intradermal vej i halen på 10 Sprague-Dawley hanrotter med en middelvægt på 150 g.
Efter 15 dage udvælges de dyr, som udviser de mest udtalte artritis-symptomer. Disse rotter deles i to grupper på 14 dyr.
Dyrene i den første gruppe behandles i 6 dage pr. uge i 3 uger - enten ad subkutan vej med doser fra 0,32 jumol til 32 15 /xmol/kg/dag, - eller ad oral vej med en dosis på 0,16 mmol (kg/dag) .
Den anden gruppe gives en placebo og tjener som kontrolgruppe.
Efter 3 ugers behandling dræbes halvdelen af dyrene i hver gruppe. Den anden halvdel opbevares uden behandling i 2 uger, 20 hvorefter den også dræbes.
Efter dræbning af dyrene fjernes den højre bagpote ved fodrodsvristen og vejes. For hver halve gruppe bestemmes middel-vægten og vægtenes standardafvigelse.
Forbindelsens virkning udtrykkes ved ændringen i procent af 25 middelvægten af de behandlede artritis-rotters poter i forhold til middelvægten af de ubehandlede rotters (kontrolrotters) artritis-poter.

Det opnåede resultat er anført i den efterfølgende tabel II. Den terapeutiske aktivitet er udtrykt som procent inhibering af potevægten efter 3 ugers behandling.
TABEL II

Resultatet viser, at forbindelserne ifølge opfindelsen har en 10 betydelig antireumatisk virkning efter 3 ugers behandling.
Det skal bemærkes, at denne virkning opretholdes på et højt niveau og undertiden endog stiger 2 uger efter behandlingens afslutning.
De omhandlede aminerede forbindelser har en antiinflammatorisk 15 og antireumatisk virkning af samme type som de nærmest beslægtede kendte forbindelser, der kan betegnes som hydrogenerede eller hydroxylerede forbindelser, men har en meget højere virkningsstyrke.
Til belysning heraf angives i· det følgende resultaterne opnået 20 ved artrit isforsøg med det i det foregående omtalte hjælpestof for to forbindelser, hvoraf den ene er en forbindelse ifølge den foreliggende opfindelse, og den anden er en fra DK patentansøgning nr. 3367/83 kendt nært beslægtet forbindelse, som bærer den samme substituent indeholdende svovl.
25 Disse to forbindelser har følgende formler: DK 168573 B1 7 cn2^0>

Resultaterne udtrykt i procent inhibering af potevægten er 5 henholdsvis: SR 43176: subkutan indgivelse: 52% ved en dosis på 0,32 μπιοΐ/kg/dag oral indgivelse: 37% ved en dosis på 0,02 mmol/kg/dag 10 SR 41903: subkutan indgivelse: 55% ved en dosis på 20 μτηοΐ/kg/dag oral indgivelse: 22% ved en dosis på 0,16 mmol/kg/dag.
Disse tal viser således, at ved subkutan indgivelse opnås i 15 det væsentlige den samme virkning med den dosis af SR 43176, der er mere end 60 gange lavere end dosen af SR 41903, medens der ved oral indgivelse opnås en meget højere virkning (37% mod 22%) med en dosis af SR 43178, som er 8 gange mindre end. dosen af SR 41903.
