Description
l5 20 25 30 35 7807404-4 2 med den glattmuskelrelaxerande effekten. I vissa fall har de vaso- dilaterande effekterna också haft en negativ effekt på hjärtats kontraktilitet.
Det framgår därav att utvecklingen av specifika glattmuskelrelaxe- rande medel som saknar sidoeffekter kan erbjuda en terapeutisk fördel i arteriell hypertension och för behandling av ischemisk hjärtsjukdom och av akut sviktande hjärta. Vidare kan sådana medel också vara användbara i behandling av andra tillstånd med förhöjd aktivering av inälvsglattmuskulaturen.
Det har nu överraskande visat sig att föreningen enligt formel I (I) besitter en specifik muskelrelaxerande effekt som relaterar till det perifera vaskulära systemet varvid föreningen saknar sidoeffekter.
Substansen är avsedd att administreras oralt eller parenteralt för akut eller kronisk behandling av ovan nämnda kardiovaskulära sjukdomstillstånd.
Den nya föreningens biologiska effekter har testats och de olika tester som genomförts kommer att visas och förklaras nedan.
Den nya föreningen erhålles enligt i och för sig kända metoder. 10 15 20 25 30 35 Sålunda, a1) reageras en förening enligt formel IIa 7/, I Cl \\ Cl fiH H3CfiC%0CH3 0 0 med en förening med formel IIIa 3 °°2"s för att ge en förening enligt formel I, eller az) reageras en förening enligt formel IIb ;¿¿ Cl l \\\ Cl cH H Hscfi-c-fioczns o o med en förening enligt formel IIIb N 0 H2\\\ /”/ C=CH-C /ff - CH3 OCH3 / \ till bildning av en förening enligt formel I; eller 7807404-4 (IIa) (IIIa) (IIb) (111b) 10 15 20 25 30 35 7807404-4 bï) reageras en förening eniigt formeï IV X l 1 I \ \ ci , c \ / ”x H \o med föreningarna enïigt formierna Va och IIIa Üšcicfl c/ ocHa (v ) _ 2- \>\ a cns/ “o NH2.\\ /oczns ( ) c=cH-c ma C143/ \o til] biidning av en förening enligt formel I, e11er ba) reageras en förening enïigt formei IV ovan med föreningarna enligt formlerna Vb och VIb 0\ /oczus \ c-cnz-cš (vb) m3/ “ o - NHÄc-cn c/ 0% (vw) cH / šë 3 ti11 biidning av en förening eniigt formeï I; e11er 10 15 20 25 30 35 7807404-4 5 c]) reageras en förening enligt formel IIa med en förening enligt formel VIa Üššš ¿¿7 0 c-cH2-c_ (vIa) \ cH3 °°z"s i närvaro av ammoniak till bildning av en förening enligt formeln I, eller CZ) reageras en förening enligt formel IIb med en förening enligt formel VIb “fa ,//° _ c-cnz-cg (vw) CH I/ \ OCH 3 3 i närvaro av ammoniak, till bildning av en förening enligt formeln I; eller d) en förening enligt formel IV ovan reageras med föreningarna enligt formlerna Va och Vb ovan i närvaro av ammoniak, till bild- ning av en förening enligt formeln I.
Uppfinningen avser också varje utföringsform av förfarandet enligt vilket man utgår från en förening som erhållits som en mellanprodukt i något förfarandesteg och man genomför det felande processteget eller man avbryter processen i något steg eller vid vilket man bildar ett utgångsmaterial under reaktionsbetingelserna eller vid vilket en reaktionskomponent, möjligen i form av dess salt, är närvarande.
Utgångsmaterialen är kända eller om de är nya kan erhållas enligt i och för sig kända förfaranden. 10 15 20 25 30 35 7807404-4 Vid klinisk användning administreras föreningen enligt uppfinningen vanligtvis oralt, rektalt eller medelst injektion i form av en farmaceutisk beredning, vilken innehåller den aktiva komponenten som fri bas i kombination med en farmaceutiskt acceptabel bärare.
Med den nya föreningen enligt uppfinningen avses den fria aminbasen oavsett om föreningen är generellt eller specifikt beskriven, såsom i exemplen vari uttryck kan förekomma som icke helt anger detta.
Bäraren kan vara en fast, halvfast eller flytande spädningsmedel eller en kapsel. Dessa farmaceutiska beredningar är ett ytterligare ändamål med uppfinningen. Vanligtvis är mängden aktiv förening mellan 0.l och 99 viktprocent av beredningen, lämpligen mellan 0.5 och 20 viktprocent i beredningar för injektion och mellan 2 och 50 viktprocent i beredningar för oral administrering.
Den dagliga dosen av aktiv substans varierar och är beroende på typen av administrering men som en allmän regel är den l00 till l000 mg/dag av aktiv substans vid peroral administrering och 5 till 1000 mg/dag vid intravenös administrering.
Följande illustrerar principen och anpassningen av uppfinningen emellertid utan att vara begränsad därtill. Temperaturer är givna i °C. 1, az) Exempel l (metod a Framställning av 2,6-dimetyl-4-(2,3-diklorfenyl)-l,4-di- *zxfiteextifåífl-.âá:áilsatfzfvsxLäxtazâzflletxleïeetzâzetxleatet 2,87 g 2,3-diklorbensylidenacetylättiksyrametylester och l,3 g 3-aminokrotonsyra etylester löstes i l0 ml tertiär butanol. Reak- tionsblandningen tilläts stå vid rumstemperatur under 4 dagar, varefter tertiärbutanolen avdunstades och återstoden löstes och rördes med en mindre mängd isopropyleter, varvid föreningen kri- 10 l5 20 25 30 35 7807404-4 stalliserade. Efter rekristallisation ur isopropyleter erhölls ren 2,6-dimetyl-4-(2,3-diklorfenyl)-l,4-dihydropyridin-3,5-dikarboxyl- syra-3-metylester-5-etylester. Smp. l45°C. Utbyte 75%.
Exempel 2 (metod cl, cz) 5,74 g 2,3-diklorbensylidenacetylättiksyra metylester, 2,6 g etyl- acetoacetat och 2,8 ml konc. NH3 löstes i 25 ml tert. butanol.
Reaktionsblandningen tilläts stå i rumstemperatur under 5 dagar, varpå den tertiära butanolen avdunstades och återstoden löstes i isopropyleter. Efter avkylning kristalliserade föreningen och efter rekristallisation ur isopropyleter erhölls ren 2,6-dimetyl-4- (2,3-diklorfenyl)-l,4-dihydropyridin-3,5-dikarboxylsyra-3-metyleste:~ -5-etylester. Smp. l45°C. Utbyte 59%. ßiologiska försök Den antihypertensiva effekten hos föreningen testades på medvetna, ohämmade spontanhypertensiva råttor (SHR) av Okamoto-stamen.
Djuren hade preparerats genom tidigare inplantation av inlagda katetrar i kroppsaortan via femoralartären. Medelartärblodtrycket (MABP) och hjärthastigheten mättes kontinuerligt. Efter en 2 timars kontrollperiod administrerades den förening som skulle studeras genom oral intubering med 2-timmarsintervaller suspenderad i meto- cel-lösning (5 ml/kg kroppsvikt). De kumulerade doserna var l, 5 och 25 pmol/kg kroppsvikt. Det antihypertensiva svaret, d v s reduktionen av BP vid varje dos uttrycktes som en procent av det initiala kontroll-BP-värdet och avsattes mot dosen på en logarit- misk skala. Den dos som skulle ge 20 procents reduktion av BP bestämdes sedan genom interpolering. Resultaten visas i tabell l.
Specificiteten mot glattmuskelrelaxation undersöktes som följer: Den isolerade portalvenspreparationen från Nistar-råttor monterades i ett organbad tillsammans med en stimulerad, isolerad papillar- hjärtmuskelpreparation från samma djur. Den integrerade kontraktili- tetsaktiviteten hos portalvensglattmuskel och toppkraftsamplituden l0 15 gm 25 30 7807404-4 hos papillära, myokardiella preparationen avlästes. De respektive aktiviteterna under en 30 minuters kontrollperiod angavs som lOO% och de uppkomna aktiviteterna under påverkan av ett medel som skulle studeras uttrycktes som procent därav. Medlet administrerades med 10 minuters intervaller och potensen för vasodilatation (-log ED50 för portalvenen) och den för myokardiell depression (-log ED50 för papillarmuskeln) bestämdes genom interpolering ur det koncentration-effektförhâllande som bestämts i varje experiment.
Ett "separations"-värde erhölls för varje förening genom att ta medelvärdena för skillnaderna av -log ED50-värdena för vasodilatation respektive myokardiell depression som erhållits i experimenten.
Detta logaritmiska separationstal omsattes i numerisk form och infördes i tabell l.
