Blandt de salte, som dannes med baser, kan man nævne alkalimetalsaltene såsom natrium-eller kaliumsaltene og aminsaltene, f.eks. af triethylamin eller dimethylamin.
Opfindelsen angår især forbindelserne med formlen I, hvor R2 betegner methyl eller benzyl, og 15 navnlig sådanne, hvor R2 betegner benzyl, samt deres additionssalte med syrer og baser og især sådanne, hvor R3 betegner phenyl, som eventuelt er substitueret med et eller flere chlor-atomer eller med en eller flere methoxygrupper, eller R3 betegner en pyridinylgruppe, samt deres additionssalte med syrer og baser.
20 Blandt forbindelserne ifølge opfindelsen skal især nævnes de forbindelser, som omhandles i eksemplerne, og navnlig: a-mercaptomethyl)-N-phenyl-benzenpropanamid, ethanthiosyre-S-(3-oxo-3-(phenylamino)-2-(phenylmethyl)-propyl)-ester, a-(mercaptomethyl)-N-(3-methoxyphenyl)-benzenpropanamid, 25 a-(mercaptomethyl)-N-(4-methoxyphenyl)-benzenpropanamid, a-(mercaptomethyl)-N-(4-pyridinyl)-benzenpropanamid samt deres additionssalte med syrer og baser.
Opfindelsen angår ligeledes fremgangsmåder til fremstilling af forbindelserne med formlen I, 30 og disse fremgangsmåder er ejendommelige ved det i den kendetegnende del af krav 8 og 9 anførte.
De funktionelle derivater af syrerne med formlen II og IV er fortrinsvis syrechloriderne.
35 I forbindelse med formlen IV erX-j fortrinsvis et chloratom.
Omsætningerne til kondensation mellem forbindelserne med formlerne II eller IV og forbindelserne med formlen III udføres i et opløsningsmiddel såsom ether, tetrahydrofuran, et chloreret 2 DK 169668 B1 opløsningsmiddel især methylenchlorid, 1,1-dichlorethan, chloroform eller carbontetrachlorid eller en keton især acetone eller methylethylketon.
Forbindelserne med formlen I defineret som ovenfor samt deres additionssalte med syrer og 5 baser har interessante farmakologiske egenskaber. De har navnlig meget interessante egenskaber til inhibering af enkephalinase og har en meget god smertestillende virkning.
Enkephalinase er en dipeptidylcarboxypeptidase, som specifikt hydrolyserer methionin- og leucinenkephalin mellem tredje og fjerde aminosyre, hvorved der frigøres et tripeptid Tyr-Gly-10 Gly (Sverts, J.P.; Perdrisot, R.; Patey, G.; De La Baume, S. og Schwartz, J.C.; Europ. J. Pharmacol., 1979, b. 57, s. 279).
Enkephalinase deltager således direkte i den fysiologiske nedbrydning af enkephalineme, som er naturlige endogene ligander for opiat-receptorer. Forbindelserne ifølge opfindelsen, som 15 forsinker nedbrydningen af enkephalineme, stimulerer således organismens forsvarsreaktioner mod smerter.
Disse egenskaber retfærdiggør deres anvendelse i terapien, og opfindelsen angår ligeledes som lægemidler forbindelserne med formlen I samt additionssaltene med farmaceutisk accep-20 table syrer og baser af forbindelserne med formlen I.
Den foreliggende opfindelse angår især som lægemidler a-(mercaptomethyl)-N-phenyl-benzen-propanamid, ethanthiosyre-S-(3-oxo-3-(phenylamino)-2-(phenylmethyl)-propyl)-ester, a-(mer-captomethyl)-N-(3-methoxyphenyl)-benzenpropanamid, a-(mercaptomethyl)-N-(4-methoxyphe-25 nyl)-benzenpropanamid og a-(mercaptomethyl)-N-(4-pyridinyl)-benzenpropanamid samt deres additionssalte med farmaceutisk acceptable syrer og baser.
Lægemidlerne kan benyttes til behandling af muskel-, led- eller nervesmerter, reumatiske lidelser, tandpine, zona og migræne samt til behandling af betændelsessygdomme, især arthrosis, 30 lumbago samt til komplementær behandling af infektions- og febertilstande.
Opfindelsen omfatter også farmaceutiske præparater, der som aktiv bestanddel indholder de omhandlede lægemidler.
35 Disse præparater kan indgives ad oral, rektal, parenteral eller lokal vej, i sidste tilfælde ved topisk påføring på huden og slimhinderne.
3 DK 169668 B1
Præparaterne kan være faste eller flydende og kan foreligge i de i den humane medicin gængs benyttede farmaceutiske former, f.eks. uoversukrede eller oversukrede tabletter, gelatine-kapsler, granulat, stikpiller, injektionspræparater, pomade, creme, geler og aerosolpræparater.
De fremstilles efter de gængse metoder. Den aktive bestanddel kan inkorporeres deri sammen 5 med i disse farmaceutiske præparater normalt benyttede tilsætningsstoffer såsom talkum, gummi arabicum, lactose, stivelse, magnesiumstearat, kakaosmør, vandige eller ikke-vandige bærestoffer, fedtstoffer af animalsk eller vegetabilsk oprindelse, paraffinderivater, glycoler og diverse fugte-, dispergerings- eller emulgeringsmidler samt konserveringsmidler.
10 Dosen varierer især i afhængighed af indgiftsmåden, den behandlede lidelse og den pågældende patient.
F.eks. kan dosen hos voksne variere fra 20 mg til 2 g aktivt stof pr. dag ad oral vej.
15 Visse af forbindelserne med formlen II og IV, der benyttes som udgangsforbindelser ved en af fremgangsmåderne ifølge opfindelsen, er beskrevet i US patentskrift nr. 4.053.651.
De forbindelser med formlen II og IV, som ikke er beskrevet i dette patentskrift, kan fremstilles som angivet i dette patentskrift.

Biologisk undersøgelse 1. Bestemmelse af enkephalinase samt bestemmelse af virkningen af inhibitorerne Aktiviteten af enkephalinase bestemmes i en membranfraktion af striatum fra rotte.
30
Striatum fjernes på is og homogeniseres i en stødpude af TRIS 0,05 M, pH 7,4 (20 x rumfang).
Efter en første centrifugering ved 1000 g fås den partikulære fraktion efter to centrifugeringer på 10 minutter ved 2000 g. Bundstoffet suspenderes derpå i en TRIS-stødpude og opbevares ved 4°C. Bestemmelsen af proteinerne udføres ved metoden med Coomassie-blåt.
Efter en forinkubering på 15 minutter ved 25°C inkuberes en proteinportion i 15 minutter ved 25°C i nærværelse af 20 nanomol på den første aminosyre af tritiumhoidigt leucin-enkephalin, som er renset i forvejen, 1 mM puromycin og forbindelsen, som skal undersøges, i TRIS-stød- 35 12 DK 169668 B1 pude. Hydrolysereaktionen stoppes ved tilsætning af 0,2 N saltsyre, og inkubatet undergår en deproteinisering ved varmepåvirkning (15 minutter ved 95°C). Under disse betingelser er reaktionens kinetik lineær.
5 De ved hydrolyse opnåede tritiumholdige metabolitter skilles fra enkephalinet ved chromato-grafi på en søjle med porapak Q. De elueres i TRIS-stødpude, medens enkephalinet tilbageholdes på søjlen og derpå fås i ethanolfase.
Aktiviteten af de forskellige stoffer udtrykkes i 50% inhiberende koncentrationer.

Teknikken består i at efterforske den smertestillende virkning på en rotte, hvis følsomhedstær-skel for smerter er sænket ved en betændelse.
20 Betændelsen opnås ved indsprøjtning af carragenin (0,25 mg pr. pote) under den plantære aponeurose på en bagpote. Smerten frembringes ved mekanisk tryk mod den dorsale side af poten og forøges regelmæssigt ved hjælp af et analgesimeter.
Smertetærsklen vurderes ved det tryk, som er nødvendigt til udløsning af en reaktion bestå-25 ende i tilbagetrækning af poten eller et skrig fra dyret.
Stofferne indgives ad oral vej 4 timer efter indsprøjtningen af det irriterende stof, og målingerne af smertetærskel udføres umiddelbart før indsprøjtningen af det irriterende stof og derpå 1 time efter behandlingen.
