Description
DK 159424 B
Den foreliggende opfindelse angår 5-acyl-2-(lH)-py-ridinoner, der er ejendommelige ved, at de har formlen
p H
5 (I) *6 jT* 0 hvor R3 er H eller -CN, R5 er phenyl, phenyl, som er substitueret med lavere alkyl-10 thio, eller lavere alkoxy, og R6 er methyl eller ethyl, eller er pharmaceutisk acceptable syreadditionssalte deraf.
Disse forbindelser er anvendelige som cardiotoniske midler ved behandlingen af hjerteforstyrrelse og andre tills stande, der kræver styrkelse af hjertevirksomheden med et cardiotonisk middel.
Som udtrykket anvendes her, omfatter "alkyl" ligekæ-dede eller forgrenede, mættede aliphatiske kulbrintekæder.
I en substitueret phenylgruppe R5 er substituenten fortrins-20 vis anbragt i parastilling, men kan være i ortho- eller meta--stilling. Udtrykket "lavere" omfatter, når det anvendes om alkyl, alkoxy og alkylthio, sådanne grupper, der har 1-6 carbonatomer.
Forbindelserne med formlen I er anvendelige både i 25 form af den frie base og i form af syreadditionssaltene, hvor begge former er omfattet af den foreliggende opfindelse. Syreadditionssaltene er ganske enkelt en mere egnet form til brug, og i praksis svarer anvendelsen af saltet til anvendelsen af den frie base. Syrerne, der kan anvendes, 30 omfatter sådanne, der, når de kombineres med den frie base, giver pharmaceutisk acceptable salte, dvs. salte, hvis an-ioner er forholdsvis uskadelige for dyreorganismen i saltenes pharmaceutisk anvendelige doser. I praksis er det bedst at danne sulfat-, phosphat-, methansulfat- eller lactatsalte.
35 Andre er sådanne, der er afledt ud fra mineralsyrer (f.eks. saltsyre), og organiske syrer såsom eddikesyre, citronsyre,
DK 159424 B
2 vinsyre, ethansulfonsyre, benzensulfonsyre, p-toluensulfon-syre og lignende. Syresaltene fremstilles ved standardmetoder såsom ved at opløse den frie base i vandig eller vandig-al-kohol-opløsning eller andre egnede opløsningsmidler, der 5 indeholder den rigtige syre, og isolere ved at afdampe opløsningsmidlet, i hvilket tilfælde saltet udskilles direkte eller kan fås ved koncentrering af opløsningen.
Almindeligvis fremstilles forbindelserne ifølge opfindelsen ved standardmetoder, der er analoge til de på 10 området kendte. En foretrukket syntese til fremstilling af forbindelserne ifølge opfindelsen indebærer omsætning af en passende l-R5“3-Rg-2-(1-dimethylamino-l-methylidenyl)-1,3--propandion (II) med cyanoacetamid ifølge standardbetingelserne ved Michael-additionsreaktion. Fortrinsvis omsættes 15 det substituerede acetamid med natriumhydrid under argon i et inaktivt organisk opløsningsmiddel (f.eks. tetrahydrofu-ran) til dannelse af en anion, som derpå kondenseres med diketonen (II) ved at opvarme reaktanterne sammen i et inaktivt organisk opløsningsmiddel, fortrinsvis tetrahydrofuran 20 og lignende. Fortrinsvis ligger reaktionstemperaturen på i ca. 50°C, men reaktionen forløber udmærket ved temperaturer mellem stuetemperatur og 100°C. Opvarmning sker over et tidsrum på flere timer, men det foretrækkes at lade reaktionen forløbe natten over. Når R5 og Rg ikke er ens, fås 25 en blanding af produkter, som adskilles ganske godt ved lynchromatografi, hvor reaktionsproduktblandingen blandes med 60-200 mesh silicagel, og kolonnen elueres med et passende opløsningsmiddelsystem (f.eks. 35% ethylacetat/65% methylenchlorid). Eluatfraktionerne overvåges ved tyndtlags-3 0 chromatografi.
Den ovennævnte reaktion kan afbildes som følger:

l-R5-3Rg-2-[ (1-Dimethylamino) alkylidenyl] -1,3-propan-dionerne kan let fremstilles ved at kondensere passende 20 R5,Rg-l,3-propandioner med den passende N,N-dialkylamino--dialkoxymethan (f.eks. dimethylformamidacetaler) ifølge standard kondensationsreaktionsbetingelser såsom f.eks. at bringe ækvimolære mængder af reaktanterne i berøring, eventuelt i et inaktivt organisk opløsningsmiddel, og omrøre 25 blandingen i 1-12 timer ved ca. stuetemperatur. Denne reaktion kan afbildes som følger.

I de tilfælde, hvor R3-substituenten er hydrogen, foretrækkes det kemisk at fjerne en cyanomolekyldel fra en forbindelse med formlen I ved standardteknik såsom ved omdannelse af cyanomolekyldelen til en carboxylgruppe ved 5 hjælp af behandling med en stærk syre, hvorpå forbindelsen decarboxyleres.
Fremstilling af slutprodukter.
10 Eksempel 1 5-Benzovl-l.2-dihvdro-6-methvl-2-oxo-3-pvridin- -carbonitril 2,50 g (0,03 mol) cyanoacetamid tilsættes til en omrørt suspension af natriumhydrid i 150 ml THF og opvarmes 15 til 50°C. Blandingen får lov at køle af til stuetemperatur, ------ -------- derpå tilsættes 6,52 g (0,03 mol 3-[(dimethylamino)methy- lenyl]-l-phenyl-l,3-butandion opløst i 20 ml THF på én gang. Suspensionen opvarmes og omrøres ved 50°C natten over. Reaktionsblandingen får lov at køle af til stuetemperatur, be-20 handles med eddikesyre til pH 6 og inddampes på roterende fordamper. Oparbejdning som i eksempel 5 giver 3,0 g af et gult pulver. Pulveret blandes med 10 g silicagel (60-200 mesh) og lynchromatograf er es, idet der elueres med 25% EtOAc/75% CH2CI2/ idet er opsamles 50 ml-fraktioner, hvilket 25 giver 1,1 g 5-benzoyl-l,2-dihydro-6-methyl-2-oxo-3-pyridin-carbonitril i fraktionerne 24 til 40, smeltepunkt 265-267°C.
Eksempel 2 3-Cvano-l.2-dihvdro-6-methvl-2-oxo-5-pyridin-30 carboxylsvre-ethvlester 6,5 g (0,050 mol) ethylacetoacetat og 7,14 g (0,060 mol) dimethylformamiddimethylacetat omrøres sammen under argon natten over. Den fremkomne rødligt farvede olie inddampes på roterende fordamper, og koncentratet opløses derpå 35 i 10 ml THF og tilsættes hurtigt til en suspension af 4,20 g cyanoacetamid (0,050 mol) og natriumhydrid i 175 ml THF.

Reaktionsblandingen opvarmes og omrøres natten over ved 50°C. Reaktionsblandingen neutraliseres til pH 6 med eddikesyre og inddampes på den roterende fordamper. Remanensen udrives med en 50:50 CH2Cl2/H20-blanding, opsamles og omkry-5 stalliseres (EtOAc), hvilket giver 4,7 g 3-cyano-1,2-dihydro--6-methyl-2-oxo-5-pyridincarboxylsyre-ethylester, smeltepunkt 208-210°C.

Den fremkomne røde olie inddampes på roterende fordamper, og koncentratet opløses i THP og tilsættes til en suspension af 0,84 g (0,010 mol) cyanoacetamid og 0,25 g (0,010 mol) natriumhydrid i 50 ml THF og opvarmes under konstant omrøring ved 50°C i 15 20 timer og afkøles. Blandingen indstilles til pH 6 med eddikesyre og inddampes. Remanensen opløses i CH2Cl2, ekstra-heres med 5%'s NaHC03, vaskes med saltvandsopløsning, fraskilles, tørres (MgSO^ og filtreres. Inddampning på den roterende fordamper giver et gult gummi, der efter udrivning 25 med Et20 størkner. Omkrystallisation (EtOAc) giver 1,37 g, smeltepunkt 208-210°C. HPLC (u "Bondpack" CN-kolonne, 55% MeOH/45% H20) viser to spidser i stort set et forhold på 40-60).
På lignende måde fremstilles 5-(4-methylthiobenzoyl)-30 -6-methyl-2-oxo-l,2-dihydro-3-pyridincarbonitril.
Forbindelserne med formlen I kan anvendes til behandling af hjertesvigt, herunder blodprop i hjertet, forvægs-og bagvægshjerteinfarkt, hjerteinfarkt i venstre ventrikel eller hjerteinfarkt i højre ventrikel eller til behandling 35 af en hvilken som helst anden tilstand, der kræver styrkelse af hjertefunktion med et cardiotonisk middel.

Anvendeligheden af forbindelserne med formlen I som cardiotoniske midler kan påvises ved at indgive prøveforbindelsen (0,01-10 mg/kg) intravenæst, intraperitonealt, in-traduodenalt eller intragastrisk i et passende bærestof til 5 en bastardhund (af hvert køn). Forsøgshundene anæstetiseres og forberedes, ved at en passende arterie isoleres (f.eks. lårpulsåren eller en almindelig pulsåre) og vene (f.eks. Femoral eller ydre halsvene), idet der indføres polyethylen-katetere fyldt med 0,1% heparin-Na hhv. til måling af arte-10 rieblodtryk og til indgivelse af forbindelser. Brystkassen åbnes ved spaltning af brystbenet i midtlinien eller ved indsnit ved venstre 5. ribbensmellemrum, og der formes en pericardievugge til understøtning af hjertet. En Walton--Brodie-spændingsmåler sutureres til højre eller venstre 15 ventrikel til overvågning af myocardiets sammentræknings-— kraft. Der kan anbringes en elektromagnetisk strømningssonde omkring roden af den opadgående aorta til måling af hjerteydelsen minus den koronare blodstrøm. Hjertesvigt fremkaldes ved at indgive natriumpentobarbital (20-40 mg/kg) efter-20 fulgt af en kontinuerlig infusion af 1-2 mg/kg/min. eller propranolol-hydrochlorid (4 mg/kg) efterfulgt af en kontinuerlig infusion af 0,18 mg/kg/min. til blodet, der gennemstrømmer hjertet. Efter indgivelse af et af disse hjerte-svækningsmidler, stiger trykket i højre atrium dramatisk, 25 og hjerteydelsen svækkes alvorligt. Ophævelse af disse virkninger ved hjælp af prøveforbindelsen viser, at denne har cardiotonisk virkning.
Ved anvendelse af følgende forbindelser ifølge opfindelsen opnåedes de angivne resultater:

20 Forbindelserne kan indgives på forskellige måder for at opnå den ønskede virkning. Forbindelserne kan indgives alene eller i form af farmaceutiske præparater til den patient, der behandles, enten oralt eller parenteralt, dvs. intravenøst eller intramuskulært. Den mængde forbindelse, 25 der indgives, varierer afhængigt af patienten, hjertesvigtets sværhedsgrad og indgivelsesmåden.
Til oral eller parenteral indgivelse ligger en car-diotonisk effektiv mængde forbindelse fra ca. 0,01 mg/kg patientlegemsvægt pr. dag til op til ca. 500 mg/kg patient-30 legemsvægt pr. dag og fortrinsvis fra ca. 0,10 op til ca.
200 mg/kg patientlegemsvægt pr. dag.
Til oral indgivelse kan en enhedsdosis indeholde f.eks. fra 1,0 til 750 mg af det aktive stof, fortrinsvis ca. 10 til 250 mg aktivt stof. Til parenteral indgivelse 35 kan en enhedsdosis indeholde f.eks. fra 5 til 500 mg aktivt stof, fortrinsvis ca. 10 til 250 mg. Gentagne daglige ind- 8

givelser af forbindelserne kan være ønskelige og vil variere afhængigt af patientens tilstand og indgivelsesmåden.
Som anvendt her betyder udtrykket "patient" varmblodede dyr, især pattedyr såsom mennesker.
5 Til oral indgivelse kan forbindelserne forarbejdes som faste eller flydende præparater såsom kapsler, piller, tabletter, pastiller, pulvere, opløsninger, suspensioner eller emulsioner. Faste enhedsdoseringsformer kan være en kapsel, som kan være af den almindelige gelatinetype, der 10 f.eks. indeholder smøremidler og inaktivt fyldstof såsom lactose, saccharose eller majsstivelse. Ved en anden udførelsesform kan forbindelserne med formlen I være slået til tabletter med de gængse tabletbasisstoffer såsom lactose, saccharose og majsstivelse, kombineret med bindemidler såsom 15 akacie, majsstivelse eller gelatine, disintegreringsmidler såsom kartoffelstivelse eller algininsyre og et smøremiddel såsom stearinsyre eller magnesiumstearat.
Til parenteral indgivelse kan forbindelserne indgives som injicerbare doser af en opløsning eller suspension af 20 forbindelsen i et fysiologisk acceptabelt fortyndingsmiddel med et farmaceutisk bærestof, der kan være en steril væske såsom vand, alkoholer, olier og andre acceptable organiske opløsningsmidler med eller uden tilsætning af et overfladeaktivt middel eller andre farmaceutisk acceptable hjælpe-25 stoffer. Som eksempler på olier, der kan anvendes i disse præparater, kan nævnes olier af jordolie, animalsk, vegetabilsk eller syntetisk oprindelse, f.eks. jordnøddeolie, sojabønneolie og mineralolie. Almindeligvis foretrækkes vand, saltvandopløsning, vandig dekstrose og beslægtede 30 sukkeropløsninger, ethanol og glycoler såsom propylenglycol eller polyethylenglycol eller 2-pyrrolidon, som flydende bærestoffer, især til injicerbare opløsninger.
Forbindelserne kan indgives i form af en depotinjektion eller et implanteringspræparat, der kan sammensættes 35 på en sådan måde, at der fås protraheret frigivelse af det aktive stof. Det aktive stof kan presses til pellets eller 9 UK 1 b y 4 2 4 b små cylindre og implanteres subcutant eller intramuskulært som depotinjektioner eller implantater. Til implantater kan der benyttes inaktive materialer såsom bionedbrydelige polymere eller syntetiske siliconer, f.eks. "Silastic", en 5 siliconegummiart, der fremstilles af Dow-Corning Corporation.
