Description
7800505-0 2 jšz \ Hzc/ en, l l “ ~ rfn+~ cu-coR (II) vari R har den angivna betydelsen, med en syra med formeln III: Rl- ?--H - S--CH --CH-f-COOH (III) Ra 2 vari Rl är en acylgrupp och R3 har den angivna betydelsen, varvid syran III före omsättning med aminosyran II överföres till ett aktiverat karboxylsyraderivat, såsom en blandad anhydrid, symmetrisk anhydríd, syraklorid, aktiv ester, Woodward-reagens K, N,N'-karbonyl- bisímidazol, EEDQ (N-etoxikarbonyl-2-otoxi-l,2-dihydrokinolin) eller liknande. När R är lägre alkoxi, kan denna eller andra kända metoder för koppling av sådana molekyldelar användas (en sammanställning av dessa metoder finner man i Methoden der Organíschen Chemie (Houben- Weyl), vol. XV, delarna l och 2 (1974).
Renktionskomponenterna är skyddade med lämpliga, i och för *sig kända skyddsqrupper, vilka på känt sätt avspaltas efter konden- sationen.
När den erhållna produkten är en ester, såsom då R är t-butoxi, kan estern överföras till den fria karboxigruppen (R är hydroxi) genom spaltning med syror, såsom trifluorättiksyra. Omvänt kan den fria syran förestras enligt konventionella metoder.
Utgångsmaterial med formeln III utgör derivat av aminosyran cystein, som kan framställas enligt kända metoder. :_ PQQš “išiíiilzrr 7800505-0 Produkter med formeln I har två asymmetriska kolatomer.
Föreningarna existerar således i diastereoisomera former eller i racemiska blandningar därav. Samtliga dessa ligger inom ramen för uppfinningen. Nämnda synteser kan utnyttja racematet eller den ena av enantiomererna såsom utgångsmaterial. När det racemiska utgångs- materialet användes vid syntesen, kan de erhållna stereoisomererna i produkten separeras med konventionella kromatografiska eller frak- tionerade kristallisationsmetoder. I allmänhet är L-ísomeren med hänsyn till kolatomen i aminosyran den lämpligaste isomera formen.
Föreningarna med formeln I bildar salter, som även ingår inom ramen för uppfinningen. Salterna omfattar syraadditionssalter, som bildas genom omsättning med ett flertal olika oorganiska och organiska syror, som ger syraadditionssalter, inkl. exempelvis hydrohalider (speciellt hydroklorid och hydrobromid), sulfat, nitrat, borat, fosfat, oxalat, tartrat, maleat, citrat, acetat, askorbat, succinat, bensensulfonat, metansulfonat, cyklohexansulfamat och toluensulfonat.
Salterna bildas på konventionellt sätt genom att man omsätter den fria formen av produkten med en eller flera ekvivalenter varvid ifrågavarande syra eller bas, som ger den önskade anjonen eller kat- jonen, i ett lösningsmedel eller medium, vari saltet är olösligt, eller i vatten, varefter man avlägsnar vattnet genom frystorkning.
Genom neutralisering av saltet med en olöslig syra, såsom ett katjon- bytarharts i väteformen (såsom polystyrensulfonsyraharts - Dowex SO Miles, Laboratory Handbook of Chromatographic Methods, Van Nostrand, 1961, p. 256), eluering med en flyktig buffert (såsom pyridin/ättiksyra och extraktion med ett organiskt lösningsmedel, kan den fria formen erhållas och eventuellt ett annat salt bildas.
FOOR QUALITY -q-F-ww-vá. 78ll05Û3-Û Ytterligare experimentella detaljer finner man i exemplen, vilka avser speciellt lämpliga utföringsformer och även har till upp- gift att vägleda beträffande framställningen av andra medlemmar av gruppen. I ' Föreningarna enligt uppfinningen inhiberar överföring av dekapeptiden angiotensin I till angiotensin II och är därför värde- fulla för reduktion eller lindring av angiotensinberoende hypertension.
Verkan av enzymet renin på angiotensinogen, ett pseudoglobulin i blod- plasma, ger angiotensin I. Angiotensin I överföres av angiotensin- överförande enzym (ACE) till angiotensin II. Det sistnämnda utgör en aktiv pressorsubstans, som har angetts vara det förorsakande medlet vid olika former av hypertension hos olika däggdjursarter, såsom råtta, hund, etc. Föreningarna enligt uppfinningen ingriper i angiotensinogen .q angiotensin I-9 angiotensin II-sekvensen genom att inhibera angio- tensin-överförandc enzym och reducera eller eliminera bildningen av pressorsubstansen angiotensin II. r 'Inhiberingcn av det angiotensinöverförando enzymet med före- ningar med formeln I kan bestämmas in vitro med isolerat angiotensin- överförande enzym från kaninlungor enligt den procedur som beskrives av Cushman och Cheung (Biochem. Pharmacol., gg, l637 (1971)) och med ett försök med utskuren glattmuskel (E. O'Keefe, et al., Federation Prcc. ål, 511 (1972)), varvid dessa föreningar visat sig vara kraftiga inhibitorer av den kontraktila aktiviteten hos angiotensin I och potentiatorer av den kontraktila aktiviteten hos bradykinin.
Administration av en komposition innehållande en eller flera av föreningarna med formeln I eller fysiologiskt godtagbara salter därav till arter av hypertensiva däggdjur lindrar eller reducerar hypertension. En enhetsdos, eller företrädesvis två till fyra uppdeladr daglige doser, tillhandahållna på entasis av ungefär 5-1000 mg/kg och dag, företrädesvis ungefär 10-5OÖ mg/kg och dag, är lämpliga för reduktion av blodtrycket. Djurmodellförsöken beskrivna av S.L. Engel, T.R. Schaeffer, M.H. Waugh och B. Rubin, Proc. Soc. Exp. Biol. Med., lgå, 483 (1973) utgör en värdefull vägledning.
Substansen administreras företrädesvis oralt, men.man kan även administrera den parenteralt, såsom subkutant, intramuskulärt, intra- venöst eller intraperitonealt.
Föreningarna enligt uppfinningen kan användas för âstadkommande av reduktion av blodtrycket genom att beredas i kompositioner, såsom tabletter, kapslar eller tinkturer och mixturer för oral administra- 7800503-0 tion eller i steril lösning eller suspension för parenteral administra~ tion. Ungefär lO-500 mg av en förening eller blandning av föreningar med formeln I eller ett fysiologiskt godtagbart salt blandas med en fysiologiskt godtagbar vehikel, bärare, excipient resp. bindemedel, konserveringsmedel, stabilisator, smaksättningsmedel, etc., i en enhets- doseringsform efter behov enligt vedertagen farmaceutisk praxis. Mäng- den aktiv substans i dessa kompositioner eller preparat är sådan att en lämplig dosering erhålles inom det ovan angivna intervallet.
Uppfinningen åskådliggöres närmare medelst följande exempel, vari de angivna temperaturerna avser Celsius-grader.
