Description
i DK 169409 B1 ... Den foreliggende opfindelse angår hidtil ukendte, vandopløselige, farmaceutisk acceptable salte af i 28- og 43-stillingen disubstitueret rapamycin samt et farmaceutisk præparat indeholdende sådanne salte.
5 Rapamycin er en kendt forbindelse beskrevet i US- patentskrift nr. 3.929.992 og 3.993.749. Endvidere er mono-og diacylderivater deraf beskrevet i US-patentskrift nr. 4.316.885. De foretrukne acylgrupper er aliphatiske grupper med 2-6 carbonatomer, især acetyl. Disse kendte acylderivater 10 kan ikke danne salte, og de er ikke vandopløselige.
Rapamycin er beskrevet i BE-patentskrift nr. 877.700 som værende anvendeligt til behandling af tumorer. Rapamycin er imidlertid kun meget lidt opløseligt i vand, dvs. 20 μg/ml, og specielle injicerbare formuleringer er blevet 15 udviklet til indgivelse til patienter, som beskrevet i EP-patentskrift nr. 41.795. Disse formuleringer fremstilles ved opløsning af rapamycin i et lavtkogende, organisk opløsningsmiddel (acetone, methanol, ethanol). Opløsningen blandes med et ikke-ionisk, overfladeaktivt middel, f.eks. polyoxy-20 ethyleret, hydrogeneret ricinusolie. De resulterende formuleringer er ikke fuldt tilfredsstillende af forskellige grunde. Således er de kun sparsomt opløselige i vand. Dernæst giver de overfladeaktive midler, specielt de polyoxyethyle-rede, hydrogenerede ricinusolier, irritations- og toksici-25 tetsproblemer, og det samme gælder for de organiske opløsningsmidler. Følgeligt er der et behov for et rapamycinderi-vat eller et farmaceutisk forstadium til rapamycin, som er lettere opløseligt i vand til dannelse af en sikker, injicer-bar opløsning, og som er lige så virksomt som rapamycin 30 ved behandling af tumorer.
Det har nu vist sig, at der kan syntetiseres vandopløselige, farmaceutisk acceptable salte af derivater af rapamycin. Disse salte repræsenterer forstadier til rapamycin og nedbrydes til rapamycin i nærværelse af humant plasma og 35 animalske vævshomogenisater. De her omhandlede farmaceutiske forstadier til rapamycin muliggør tilvejebringelsen af et DK 169409 B1 2 værdifuldt, farmaceutisk injicerbart præparat til behandling af tumorer i mennesker.
De her omhandlede, vandopløselige, farmaceutisk acceptable salte er salte af derivater af rapamycin, som er disub-5 stitueret i 28- og 43-stillingen i rapamycinstrukturen. Stillingsangivelserne er baseret på en strukturfastlæggelse beskrevet af Findlay et al. i Can. J. of Chem. 58, 579 (1980) og vist nedenfor.

Foretrukne vandopløselige salte af rapamycinderivater ifølge den foreliggende opfindelse er dem, hvor R-^ og R2 hver især er alkyl med 1-3 carbonatomer.
Et rapamycinderivat, der er disubstitueret i 28- og 3 DK 169409 B1 43-stillingen med en acylaminosubstituent med formlen 0 Ri 5 II /
”C"(CH2)m-N
\ *2.
hvor m, og R2 har de ovenfor angivne betydninger, frem-10 stilles ved, at man acylerer rapamycin med et acyleringsmid-del indeholdende den ovenfor viste acylaminosubstituent.
Acyleringen kan udføres ved hjælp af standardacyle-ringsmetoder, fortrinsvis under neutrale betingelser. Acyleringsmidlet kan være en syre, et syrehalogenid (dvs. chlorid 15 eller bromid), et syreanhydrid eller en aktiveret ester af acylaminosubstituenten. Syreformen af acylaminosubstituenten foretrækkes som acyleringsmiddel i nærværelse af et egnet koblingsmiddel. Det særlige koblingsmiddel kan være mest virksomt i nærværelse af en katalysator og/eller et syrebin-20 dende middel. Eksempler på foretrukne koblingsmidler er N,N1-dicyclohexylcarbodiimid, l,l'-carbonyldiimidazol, di-ethylazodicarboxylat, 2,21-dithiopyridin og N,N-diisopropyl-carbodiimid. Diethylazodicarboxylat og 2,2·-dithiopyridin kræver anvendelse af en katalysator, såsom triphenylphosphin.
25 Med disse to koblingsmidler og triphenylphosphin som katalysator foretrækkes et ikke-chloreret opløsningsmiddel, såsom en vandfri ether, f.eks. tetrahydrofuran. Med andre koblingsmidler foretrækkes almindeligvis anvendelsen af et syrebindende middel, såsom 4-dimethylaminopyridin eller 4-pyrroli-30 dinopyridin. Med sidstnævnte koblingsmidler og katalysatorer kan anvendes et sådant opløsningsmiddel som vandfrit methy-lenchlorid eller chloroform. Med syrehalogenidet (fortrinsvis syrechlorid). foretrækkes en tertiær amin, såsom pyridin eller triethylamin, som katalysator af typen' syrebindende 35 middel, og der kan anvendes et sådant opløsningsmiddel som vandfrit methylenchlorid eller chloroform.
I en foretrukket udførelsesform udføres acyleringen ved omsætning af rapamycin med en syre med formel (III) DK 169409 B1 4 O R-i II / H0C(CH2)mN (III) \ 5 R2 hvor m, R^ og R2 har de ovenfor angivne betydninger, i nærværelse af et koblingsmiddel, f.eks. et carbodiimid, såsom dicyclohexylcarbodiimid eller diisopropylcarbodiimid, eller carbonyldiimidazol. Fortrinsvis anvendes en katalysator, 10 såsom 4-dimethylaminopyridin eller 4-pyrrol idinopyridin, sammen med sådanne koblingsmidler. I en sådan reaktion er acyleringsmidlet en aktiveret ester dannet ud fra syren med formel (III) og carbodiimid-koblingsmidlet. Koblingsmidler, herunder carbodiimider, og metoder til anvendelse deraf er 15 kendte i teknikken, idet de i stor udstrækning anvendes i peptidkemien, se f.eks. E. Schroder & K. Lubke, "The Peptides", bind 1, Academic Press, New York & London 1965, og Mr. Bodanszky & M.A. Ondetti, Peptide Synthesis, 1966 Interscience USA.
20 Hvis én eller begge R^ og R2 er hydrogen, foretrækkes beskyttelse af aminfunktionen i acyleringsmidlet ved hjælp af en beskyttende gruppe, som kan fjernes under neutrale betingelser. Hvis én eller begge R^ og R2 er hydrogen, kan aminfunktionen i et sådant acyleringsmiddel f.eks. beskyttes 25 ved anvendelse af syrechlorid-hydrochloridet af acylaminosub-stituenten som acyleringsmiddel.
Syrechlorid-hydrochlorid-acyleringsmidlet kan fremstilles på kendt måde ved omsætning af syreformen af acyleringsmidlet med 1 ækvivalent hydrogenchloridgas og derefter 30 med 1 ækvivalent phosphorpentachlorid. Disse reaktioner kan udføres i vandfrit methylenchlorid. Syrechlorid-hydrochlorid-produktet kan udvindes som et bundfald eller udfældes fra toluen, hexan eller cyclohexan. Acyleringen under anvendelse af syrechlorid-hydrochloridet kan udføres på kendt måde 35 under anvendelse af en svag base, såsom pyridinurinstof, dimethylanilin eller trimethylamin som syrebindende middel.
Den foreliggende opfindelse tilvejebringer også et injicerbart, farmaceutisk præparat, som er ejendommeligt DK 169409 B1 5 ved, .at det indeholder et farmaceutisk acceptabelt bærestof og et vandopløseligt, farmaceutisk acceptabelt salt ifølge den foreliggende opfindelse. Vand eller et hvilket som helst vandbaseret bærestof, der er kendt i teknikken, kan anvendes, 5 f.eks. destilleret vand, vand indeholdende 5 vægt-% dextrose (D5W) eller en fysiologisk acceptabel saltopløsning, som skal have en pH-værdi i det neutrale område, f.eks. en normal saltopløsning eller en laetatopløsning ifølge Ringer.
Fremstillingen af typiske vandopløselige, farmaceuti-10 ske forstadier til rapamycin ifølge den foreliggende opfindelse er illustreret i eksemplerne.
