Description
Foreliggende oppfinnelse vedrører en analogifremgangsmåte for fremstilling av terapeutisk aktive cystinderivater med den generelle formel I
hvori R står for en benzyloksykarbonyl-gruppe eller en tosyl-
gruppe,
eller farmasøytisk tålbare syreaddisjonssalter derav, og fremgangsmåten er karakterisert ved at en cystyl-diklorid med den generelle formel II
omsettes med 2,4-dibrom-g-(N-metyl-N-cykloheksyl-aminometyl)-
anilin .
Disse trekk ved oppfinnelsen fremgår av patentkravet.
Det ovennevnte anilinderivat er i det følgende benevnt "brom-
heksin".
Cystyl-dikloridene med den generelle formel II kan oppnås fra de tilsvarende syrer ved hvilken som helst konvensjonell metode for omdannelse av en syre til dens syreklorid, f.eks.
ved behandling med fosforpentaklorid i et passende løsnings-
middel som f .eks. kloroform eller dietyleter. Det er ikke nødvendig å isolere eller rense dikloridet før utførelsen av fremgangsmåten i henhold til oppfinnelsen. En passende metode er å utfelle dikloridet fra reaksjonsblandingen, f.eks. ved tilsetning av ligroin (til etyleteroppløsninger) eller dietyl-
eter (til kloroformoppløsninger), foreta avfiltrering og til-sette bunnfallet til en oppløsning av bromheksin i et passende løsningsmiddel som f.eks. kloroform eller etylacetat. Rekasjonen med bromheksin foregår ved vanlig temperatur og kan om ønsket fullføres under tilbakeløp. De resulterende cystinderivater kan isoleres og renses og eventuelt omdannes til et farmasøytisk tålbart syreaddisjonssalt ved hjelp av hvilken som helst av de konvensjonelle metoder som f.eks. direkte behandling med den valgte syre i et løsningsmiddel. Salter av saltsyre, bromhydrogensyre, svovelsyre, salpetersyre, perklor-syre, fumarsyre, maleinsyre, fosforsyre, glykolsyre, melke-syre, salisylsyre, ravsyre, toluen-p-sulfonsyre, vinsyre, eddiksyre, sitronsyre, metansulfonsyre, maursyre, benzosyre, malonsyre, benzensulfonsyre og naftalen-2-sulfonsyrer fore-trekkes .
Cystinderivater fremstilt i samsvar med oppfinnelsen og salter derav har god ekspektorant og antitussiv virkning og virker fluidiserende på åndedrettskanal-fluidene, samtidig som de viser en lav giftighet. LD^^-verdien, bestemt i mus og rot-ter, både i.p. og per os, er mer enn 3000 mg/kg for alle de testede forbindelser.
Ekspektorantaktiviteten (ED^q) bestemt i kaniner i henhold til metoden til Boyd (Boyd og Shepprad, Arch. Int. Pharm. 1966, 163,284) var 100 mg/kg (I, R=benzyloksykarbonyl).
Samme ED^q, bestemt i mus i henhold til en forbedret Mava-tari-metode (Graziani, Gazzulani, Il Farmaco, Ed. Prat. 1981, XXXVI, 2» 167) var henholdsvis 1,2 mg/kg (I, R=benzyloksykarbonyl) og 3,7 mg/kg (I, R=tosyl).
Forbindelsen I (R=benzyloksykarbonyl) viste seg å være aktivt i.p. som et antitussivmiddel i en dose på 30 mg/kg (metoden til Charlier, Prost et al., Arch. Int. Pharm., 1961, 134, 306), ved inhalering av sitronsyre-aerosol i marsvin. Aktivi-teten ble bestemt som undertrykkelse av hosting.
Por å bedømme den antitussive aktivitet ble det gjennomført en annen metode. Vagusnerven ble stimulert og undertrykkelse av hosting ble påvist etter injeksjon av produktet (Pickering og Jones, Arzn. Forsch. 1979, 29_, 287). ED5ø av forbindelsene
I (R=benzyloksykarbonyl og tosyl) var henholdsvis 88 og 74 mg/kg.
Forbindelsene kan kombineres i farmasøytiske preparater inne-holdende et cystinderivat fremstilt i samsvar med oppfinnelsen eller et salt derav eller i blanding med et farmasøytisk tålbart fortynningsmiddel eller bærer.
De følgende eksempler illustrerer oppfinnelsen.
EKSEMPEL 1
N, N'- ditosyl- cystyl bis Z 2, 4- dibrom- 6-( N- metyl- N- cyklo- heksyl-aminometyl)- anilidj
Til 17,20 g N,N'-ditosyl-L-cystin oppløst i 185 ml dietyleter, ble 18,5 g fosforpentaklorid sakte tilsatt ved 20-25°C. Blandingen ble omrørt i 30 minutter og deretter ble 650 ml ligroin tilsatt. Det således dannede bunnfall ble frafiltrert og ble tilsatt en oppløsning av 27,52 g bromheksin i 74 ml kloroform ved 120-125°C. Blandingen fikk stå ved den ovennevnte temperatur i 36 timer. Hele blandingen ble ekstrahert ved kloroform og vasket først med natriumkarbonat og deretter med vann. Det organiske sjikt ble tørket med kalsiumklorid. Løsningsmidlet ble avdestillert og resten renset på en silika-kolonne under anvendelse av kloroform: etylacetat (volumfor-hold 3:2) som elueringsmiddel. Det ureagerte bromheksin ble fraseparert. Produktet, som fri base, ble tørket, oppløst i isopropanol og direkte omdannet til sitt hydroklorid ved tilsetning av hydrogenklorid i isopropanol og deretter dietyleter .
Bunnfallet ble krystallisert fra 95% etanol og dietyleter.
Smeltepunkt 191-192°C.

N, N'- dibenzyloksykarbonyl- cystyl bis 4- dibrom- 6-( N- métyl-N- cykloheksyl- aminometyl)- anilidJ
Til 10,16 g N,N'-dibenzyloksykarbonyl-L-cystin oppløst i 56 ml vannfri kloroform ble sakte tilsatt 10 g fosfor-pentaklorid ved fra -10 til 5°C.
Reaksjonsblandingen ble omrørt i 10 minutter og deretter ble 60 ml dietyleter tilsatt. Blandingen ble avkjølt i en time. Det således dannede bunnfall ble frafiltrert og tilsatt en oppløsning av 14,88 g bromheksin i 40 ml etylacetat ved 22°C. Blandingen ble omrørt ved den ovennevnte temperatur i et døgn og deretter kokt ut i tilbakeløp i 4 timer.
Etter avsluttet reaksjon ble blandingen ekstrahert med etylacetat, vasket med natriumkarbonatoppløsning, med vann, og deretter tørket over vannfritt natriumsulfat. Løsningsmidlet ble avdampet og resten ble behandlet med heksan. Produktet ble filtrert, samlet og krystallisert fra etanol. Smeltepunkt 168°C.
Ved tilsetning av hydrogenklorid i etanol ble det tilsvarende salt oppnådd som smeltet ved 195-197°C (med spaltning).
