Fremgangsmåte til fremstilling av analgetisk og Process for the production of analgesic and
narkotisk antagonistisk virksomme N-substituerte narcotic antagonistically active N-substituted
14-hydroksydihydronormorfin-forbindelser. 14-hydroxydihydronormorphine compounds.
Foreliggende oppfinnelse vedrorer en fremgangsmåte til fremstilling av nye N-substituerte 14-hydroksydihydronormorfinforbindelser med narkotisk antagonistiske egenskaper og analgetisk aktivitet. The present invention relates to a process for the production of new N-substituted 14-hydroxydihydronormorphine compounds with narcotic antagonistic properties and analgesic activity.
I mange år har det vært gjort forsok på å fremstille nye derivater av morfin, som ikke skaper tilvenning, som bibeholder analgetisk styrke og som endog er relativt frie for sidevirkninger, slik som åndedrettsdepresjon. I de fleste tilfeller har disse anstrengel-ser ikke blitt belonnet. For many years, attempts have been made to produce new derivatives of morphine, which do not create habituation, which retain analgesic strength and which are even relatively free of side effects, such as respiratory depression. In most cases, these efforts have not been rewarded.
Det har i de senere år blitt observert at når egnede sub-stituenter forbindes med nitrogenatomet i et normorfinderivat, er de resulterende forbindelser av en slik natur at de ikke skaper tilvenn- It has been observed in recent years that when suitable substituents are joined to the nitrogen atom in a normorphine derivative, the resulting compounds are of such a nature that they do not create habituation.
1 ing, og er virkelig narkotiske antagonister. Slike narkotiske antagonister er også av og til funnet å ha analgetiske egenskaper. En slik analgesti har imidlertid når den er tilstede vært kjennetegnet ved nedsatt styrke, hallucinogeniske bivirkninger og åndedrettsdepresjon. 1 ing, and are truly narcotic antagonists. Such narcotic antagonists are also occasionally found to have analgesic properties. However, such analgesia, when present, has been characterized by reduced strength, hallucinogenic side effects and respiratory depression.
Blant narkotiske antagonister har N-allyl og N-propargyl-derivatene av 14-hydroksydihydronormorfinon, som er beskrevet i britisk patent nr. 939 287, vært fremragende ved at de er sterkt-virk-ende narkose-reverserende midler og forårsaker ikke hallucinasjoner eller åndedrettsdepresjon, som er karakteristisk for andre narkotiske antagonister. Undersøkelser ved bruk av forsoksdyr har uheldigvis vist at disse forbindelser mangler analgetiske egenskaper. Among narcotic antagonists, the N-allyl and N-propargyl derivatives of 14-hydroxydihydronormorphinone, which are described in British Patent No. 939,287, have been outstanding in that they are potent anesthetic-reversing agents and do not cause hallucinations or respiratory depression , which is characteristic of other narcotic antagonists. Investigations using laboratory animals have unfortunately shown that these compounds lack analgesic properties.
Ved å studere andre derivater av 14-hydroksyhydronormorfi-non, som vonBraun (Ber. 59> 108l (1926)) har lært også å kunne være ventet å vise narkotisk antagonistisk aktivitet, ble det i forbindelse med foreliggende oppfinnelse gjort den overraskende oppdagelse at N-(3'-metyl-2'-butenyl)-14-hydroksydihydronormorfinon, N-cyklopropylmetyl-14-hydroksydihydronormorfinon og N-cyklobutylmetyl-14-hydroksydihydronormorfinon med formel I nedenunder (Z er lik 0), i motsetning til N-allyl og N-propargyl-derivatene, er analgetika såvel som narkotiske antagonister. Deres analgetiske virkning er dessuten ikke ledsaget av uonskede bivirkninger, som er karakteristisk for tidligere kjente analgetiske narkotiske antagonister. By studying other derivatives of 14-hydroxyhydronormorphinone, which von Braun (Ber. 59> 108l (1926)) has learned may also be expected to show narcotic antagonistic activity, the surprising discovery was made in connection with the present invention that N -(3'-methyl-2'-butenyl)-14-hydroxydihydronormorphinone, N-cyclopropylmethyl-14-hydroxydihydronormorphinone and N-cyclobutylmethyl-14-hydroxydihydronormorphinone of formula I below (Z is equal to 0), in contrast to N-allyl and The N-propargyl derivatives are analgesics as well as narcotic antagonists. Moreover, their analgesic effect is not accompanied by unwanted side effects, which are characteristic of previously known analgesic narcotic antagonists.
Det er videre oppdaget at hensiktsmessig substituerte 14- It has further been discovered that suitably substituted 14-
hydroksydihydronormorf iner med formel I nedenunder (Z er hydroxydihydronormorphines of formula I below (Z is
frem- forward
stilt som mellomprodukter ved fremgangsmåten til fremstilling av 14-hydroksydihydronormorf inoner, også er narkotiske antagonister med nyttige analgetiske egenskaper. posed as intermediates in the process for the production of 14-hydroxydihydronormorph inones, are also narcotic antagonists with useful analgesic properties.
Ved undersøkelse av begrensningene for denne oppdagelse, ble N-allyl og N-propargyl-derivatene av 14-hydroksydihydronormorfin fremstilt og man ble svært overrasket ved å finne at disse forbindelser, i motsetning til 14-hydroksydihydronormorfinonene i britisk patent nr. 939 287, også er kraftige analgetika såvel som narkotiske antagonister. Denne oppdagelse er motsatt til alt det som er tidligere kjent som konsekvent har lært (britisk patent nr. 975 601 og britisk patent nr. 975 602) den kvalitative ekvivalens mellom 6-keto-og 6-hydroksy-forbindelser i morfin-seriene. In examining the limitations of this discovery, the N-allyl and N-propargyl derivatives of 14-hydroxydihydronormorphine were prepared and one was very surprised to find that these compounds, unlike the 14-hydroxydihydronormorphinones of British Patent No. 939,287, also are powerful analgesics as well as narcotic antagonists. This discovery is contrary to all that is previously known which has consistently taught (British Patent No. 975,601 and British Patent No. 975,602) the qualitative equivalence between 6-keto and 6-hydroxy compounds in the morphine series.
Ifolge foreliggende oppfinnelse er det således tilveiebragt en fremgangsmåte til fremstilling av analgetisk og narkotisk antagonistisk virksomme N-substituerte derivater av 14-hydroksydihydro-normorf in-f orbindelser med formelen: According to the present invention, a method has thus been provided for the production of analgesically and narcotic antagonistically active N-substituted derivatives of 14-hydroxydihydro-normorph compounds with the formula:

Fremstillingen av forbindelsene ifolge oppfinnelsen kan eksemplifiseres ved hjelp av det senere angitte diagram, som illustrerer fremstillingen av N-cyklobutylmetyl-14-hydroksydihydrono.rmor-finon og N-cyklobutylmetyl-14-hydroksydihydronormorfin. Beslektede fremgangsmåter gir de andre forbindelsene som fremskaffes ved oppfinnelsen. The production of the compounds according to the invention can be exemplified with the help of the diagram given later, which illustrates the production of N-cyclobutylmethyl-14-hydroxydihydronormorphinone and N-cyclobutylmethyl-14-hydroxydihydronormorphine. Related processes provide the other compounds provided by the invention.
Når den substituerte reagens er i oksydert form, må kraftige reduserende midler slik som litiumaluminiumhydrid, kaliumborhydrid i nærvær av litiumklorid, aluminiumhydrid i nærvær av aluminiumklorid, natriumborhydrid i nærvær av aluminiumklorid, diboran og lignende, benyttes for å redusere amidkarbonyl-gruppen i mellompro-duktet. Slike reduksjonsmidler reduserer også ketonkarbonylgrupper til alkoholer. Hvis det er onskelig å bibeholde ketonkarbonyl i sluttproduktet•kan det enten beskyttes under reduksjonen ved midler-tidig omdannelse til en acetal, slik som cyklisk etylenacetal, cyklisk trimetylenacetal, en lavere alkylacetal slik som dimetylacetal eller dipropylacetal, en lavere alkylenoleter, slik som metyleter, etyleter eller butyleter, eller en lignende gruppe som er motstands-dyktig mot hydrid-reduksjonen, eller det kan tillates å gjennomgå reduksjon til alkoholen og kan senere re-oksyderes til keton-gruppen ved Oppenauer oksydasjon ved bruk av kalium t-butoksyd og benzofenon, aluminiumisopropoksyd og 1-tetralon eller et beslektet reagenspar, eller ved hjelp av en annen oksydasjonsprosess som omfatter reagenter slik som kromsyre, kromtrioksyd i pyridin eller lignende. When the substituted reagent is in oxidized form, strong reducing agents such as lithium aluminum hydride, potassium borohydride in the presence of lithium chloride, aluminum hydride in the presence of aluminum chloride, sodium borohydride in the presence of aluminum chloride, diborane and the like must be used to reduce the amide carbonyl group in the intermediate . Such reducing agents also reduce ketone carbonyl groups to alcohols. If it is desired to retain the ketone carbonyl in the final product• it can either be protected during the reduction by temporary conversion to an acetal, such as cyclic ethylene acetal, cyclic trimethylene acetal, a lower alkyl acetal such as dimethyl acetal or dipropyl acetal, a lower alkylenol ether such as methyl ether, ethyl ether or butyl ether, or a similar group resistant to the hydride reduction, or it may be allowed to undergo reduction to the alcohol and may later be re-oxidized to the ketone group by Oppenauer oxidation using potassium t-butoxide and benzophenone, aluminum isopropoxide and 1-tetralone or a related reagent pair, or by means of another oxidation process comprising reagents such as chromic acid, chromium trioxide in pyridine or the like.
Reduksjonen av 6-ketokarbonyl til 6-hydroksylgruppen er en prosess som teoretisk er i stand til å frembringe to isomere produkter. Fremgangsmåten ifolge foreliggende oppfinnelse er ment å an-vendes på de produkter som leder til de urene reaksjonsprodukter (som kan være isomere blandinger) såvel som de som leder til de endelige rene produkter. The reduction of the 6-ketocarbonyl to the 6-hydroxyl group is a process theoretically capable of producing two isomeric products. The method according to the present invention is intended to be used on the products that lead to the impure reaction products (which may be isomeric mixtures) as well as those that lead to the final pure products.
I overensstemmelse med fraværet av bivirkninger, har forbindelsene som fremstilles ifolge oppfinnelsen meget lav toksisitet, idet den subkutane LD^q (dose som dreper $ 0% av dyrene) er mellom 400 og 600 mg per kg i mus. In accordance with the absence of side effects, the compounds produced according to the invention have very low toxicity, the subcutaneous LD^q (dose that kills $ 0% of the animals) being between 400 and 600 mg per kg in mice.
For å demonstrere forbindelsenes analgetiske virkning og således for å indikere bruken av disse midler som analgetika som ikke skaper tilvenning hos dyr og mennesker, ble N-(3,-metyl-2'-butenyl)-14-hydroksydihydronormorfinon, i form av dets.hydrokloridsalt, injisert intramuskulært og postoperativt i et menneske. Den analgetiske virkning frembragt av en dose på 35 mg> var omtrent den samme som den som bite frembragt av en dose på 15 mg morfinsulfat eller av en dose på 100 - 200 mg meperidinhydroklorid. I tillegg til dette, hvilket er mer viktig, ble det funnet at forbindelsen ikke medforte bivirkninger, hvilket har hemmet alle de tidligere kjente analgetika som ikke skaper tilvenning. In order to demonstrate the compounds' analgesic effect and thus to indicate the use of these agents as non-addictive analgesics in animals and humans, N-(3,-methyl-2'-butenyl)-14-hydroxydihydronormorphinone, in the form of its hydrochloride salt, injected intramuscularly and postoperatively in a human. The analgesic effect produced by a dose of 35 mg> was about the same as that produced by a dose of 15 mg of morphine sulphate or by a dose of 100-200 mg of meperidine hydrochloride. In addition to this, which is more important, the compound was found to have no side effects, which has inhibited all the previously known non-habit forming analgesics.
For å illustrere den narkotiske antagonistiske virkning til forbindelsene som fremstilles ifolge oppfinnelsen, og således for å indikere bruken av disse midler for motvirkning av narkotisk over-dose, ved undersokelse av narkotisk misbruk, og post-operativt for å fremskynde restitusjon fra operasjon eller fodsel etter narkotisk analgesi (hos dyr eller mennesker), ble rotter narkotisert med 0.4 To illustrate the narcotic antagonistic action of the compounds prepared according to the invention, and thus to indicate the use of these agents for counteracting narcotic overdose, in the investigation of narcotic abuse, and post-operatively to accelerate recovery from surgery or childbirth after narcotic analgesia (in animals or humans), rats were anesthetized with 0.4
mg oksymorfon per kg. Dyrene, som falt om på siden, ble deretter innsproytet subkuntant med så lite som 0.005 mg N-cyklopropylmetyl-14-hydroksydihydronormorfinon per kg. De 'ble raskt vekket fra sin be-dovede tilstand og bragt tilbake til normal årvåkenhet, aktivitet og bevegelsesevne. mg oxymorphone per kg. The animals, which were recumbent, were then injected subcutaneously with as little as 0.005 mg of N-cyclopropylmethyl-14-hydroxydihydronormorphinone per kg. They were quickly roused from their sedated state and brought back to normal alertness, activity and ability to move.
Narkotisk antagonistisk styrke er ikke direkte beslektet Narcotic antagonist potency is not directly related
med analgetisk, fordi N-cyklopropylmetyl-14-hydroksydihydronormorfinon, som har analgetiske egenskaper i rotter, er omtrent to ganger så sterktvirkende som et antagonistisk middel som N-allyl-14-hydroksydihydronormorfinon, som ikke har noen analgetisk styrke. with analgesic, because N-cyclopropylmethyl-14-hydroxydihydronormorphinone, which has analgesic properties in rats, is about twice as potent an antagonist as N-allyl-14-hydroxydihydronormorphinone, which has no analgesic potency.
Selv om en forbindelse slik som N-allyl-14-hydroksydihydronormorfinon er nær beslektet i struktur med de forbindelser som fremstilles ifolge oppfinnelsen gjorde man den ytterligere betydelige oppdagelse at de analgetiske virkninger, som frembringes ved hjelp av forbindelsene ifolge oppfinnelsen, kan motvirkes av N-allyl-14-hydroksydihydronormorfinon. De nye forbindelsene er derfor, selv om de er kjemisk beslektet, biologisk forskjellige fra deres forut beskrevne slektning. Although a compound such as N-allyl-14-hydroxydihydronormorphinone is closely related in structure to the compounds produced according to the invention, the further significant discovery was made that the analgesic effects produced by the compounds according to the invention can be counteracted by N- allyl-14-hydroxydihydronormorphinone. The new compounds, therefore, although chemically related, are biologically different from their previously described relatives.
Den ikke-tilvennende natur til de forbindelser som fremstilles ifolge oppfinnelsen, ble demonstrert gjennom negative for-soksresultater hos aper, som var fysisk avhengige av narkotika. Dessuten fremkalte de nevnte forbindelser ikke narkose hos rotter eller den stimulering (inkludert Straub's halefenomen) hos mus, som er karakteristisk for alle analgetika som skaper tilvenning. The non-addictive nature of the compounds prepared according to the invention was demonstrated by negative experimental results in monkeys, which were physically dependent on drugs. Moreover, the compounds mentioned did not induce narcosis in rats or the stimulation (including Straub's tail phenomenon) in mice which is characteristic of all habit forming analgesics.
En del av den dyre-farmakologi som samlet seg i lopet av Part of the animal pharmacology that gathered in the course of
de foretatte studier, er oppsummert i tabellene I og II. Vridnings-forsoket for analgesi som beskrevet av Blumbert et al (Proe.Soc.Biol. Med. Il8, 763 (1965))) hie benyttet ved bedommelse av forbindelsene. the studies carried out are summarized in tables I and II. The torsion test for analgesia as described by Blumbert et al (Proe.Soc.Biol. Med. II8, 763 (1965))) was used in evaluating the compounds.
Forbindelsene er spesielt nyttige i form av addisjonssalter av disse med farmasoytisk akseptable syrer som f.eks. saltsyre, svovel-syre, sitronsyre og de andre syrene, av hvilke det finnes mange, som vanligvis benyttes på det farmasøytiske området i forbindelse med ad-ministrasjon av nitrogenholdige forbindelser. The compounds are particularly useful in the form of addition salts thereof with pharmaceutically acceptable acids such as e.g. hydrochloric acid, sulfuric acid, citric acid and the other acids, of which there are many, which are usually used in the pharmaceutical field in connection with the administration of nitrogenous compounds.
Doseringene av forbindelsene er: for narkotisk antagonisme ca. 0.1 til 10 mg; og for analgesi ca. 0.5 til 50 mg. The dosages of the compounds are: for narcotic antagonism approx. 0.1 to 10 mg; and for analgesia approx. 0.5 to 50 mg.
Disse nye forbindelser i form av deres farmasoytisk akseptable syre-addisjonssalter, kan administreres, for narkotisk antagonisme, fra ampuller eller små flasker. For analgesi kan disse forbindelsene, i form av deres ovenfor nevnte salter eller frie base, i tillegg til de nevnte småflasker eller ampuller, tildannes som tab-letter (for subkutan, sublingual eller oral bruk, sammenblandet i overensstemmelse med kjente farmasøytiske metoder), eller som væsker, f.eks. sirup og elixirer, eller som rektale suppositorier, osv. These new compounds in the form of their pharmaceutically acceptable acid addition salts can be administered, for narcotic antagonism, from ampoules or vials. For analgesia, these compounds, in the form of their above-mentioned salts or free base, in addition to the aforementioned vials or ampoules, can be formulated as tablets (for subcutaneous, sublingual or oral use, compounded in accordance with known pharmaceutical methods), or as liquids, e.g. syrups and elixirs, or as rectal suppositories, etc.
Kort sagt; i doserende eller utleverende former som kombinasjoner av den aktive forbindelse og en akseptabel bærer. In short; in dosage or delivery forms such as combinations of the active compound and an acceptable carrier.

Method e) To 2450 ml of a molar solution of borane in tetrahydrofuran, cooled to below 0°C in a 12 liter flask with a round bottom protected from moisture and kept under a continuous stream of nitrogen, in the course of 25 minutes added a solution of 216 g of N,0-bis(cyclobutylcarbonyl)-14-hydroxydihydronormorphinone in 1 liter dry tetrahydrofuran with continuous stirring while the temperature was maintained between -5° and 0°C. After the addition was complete, the reaction mixture was refluxed for 90 minutes. It was then cooled and stirred and 500 ml of 3 N hydrochloric acid was slowly added resulting in a vigorous effervescence. The formed precipitate was filtered off, dissolved in 4 liters of water, filtered and the filtrate was brought to pH 9.3 - 9.5 with concentrated ammonium hydroxide. After filtration, the residue was washed with water and dried which gave a product with a melting point of 225°-228°C, which after crystallization was identical to the product obtained according to method (a) in this example.
Som et alternativ ble N,0-bis(cyklobutylkarbonyl)-14-hydrok-sydihydronormorf inon omrort i en ekvivalent mengde av en molar opp-låsning av natriumborhydrid i diglyme (dietylenglykoldimetyleter.) under anvendelse av samme metodikk som angitt ovenfor, og under kontinuerlig omroring. Deretter ble 1/6 av volumet av en to molar opp-lesning av vannfritt aluminiumklorid i diglyme tilsatt i lopet av 20 minutter under opprettholdelse av temperaturen mellom -5° og 0°C. fitter at tilsetningen var ferdig, ble reaksjonsblandingen oppvarmet' til 75°C i 90 minutter. Etter en lignende bearbeidelse som angitt ovenfor, ble det oppnådd et produkt som etter krystallisering fra metanol-aceton var identisk med produktet oppnådd ifolge metode (a) ovenfor. Alternatively, N,0-bis(cyclobutylcarbonyl)-14-hydroxydihydronormorphinone was stirred in an equivalent amount of a molar unlocking of sodium borohydride in diglyme (diethylene glycol dimethyl ether.) using the same methodology as stated above, and under continuous agitation. Then 1/6 of the volume of a two molar reading of anhydrous aluminum chloride in diglyme was added over the course of 20 minutes while maintaining the temperature between -5° and 0°C. After the addition was complete, the reaction mixture was heated to 75°C for 90 minutes. After a similar treatment as indicated above, a product was obtained which, after crystallization from methanol-acetone, was identical to the product obtained according to method (a) above.
Eksempel 9 N- propyl- 14- hydroksydihydronormorfinhydroklorid Example 9 N-propyl-14-hydroxydihydronormorphine hydrochloride
En porsjon på 28.7 g av 14-hydroksydihydronormorfinon ble blandet med 15.0 g N-propylbromid og 150 ml dimetylformamid og oppvarmet på et dampbad i 4 timer. Den resulterende opplosning ble inndampet til torrhet, fortynnet med 100 ml vann, .regulert til pH 9. 2 med konsentrert,vandig ammoniakk og ekstrahert med kloroform. Noe uomdannet 14-hydroksydihydronormorfinon var uoppløselig og ble fjernet på dette stadium. Kloroformopplosningen ble konsentrert og resten krystallisert fra metanolkloroform, smeltepunkt ca. 151°C. <R>n del av basen ble videre renset som hydrokloridsaltet, smeltepunkt 219°-222°C, fra metanol-aceton. A portion of 28.7 g of 14-hydroxydihydronormorphinone was mixed with 15.0 g of N-propyl bromide and 150 ml of dimethylformamide and heated on a steam bath for 4 hours. The resulting solution was evaporated to dryness, diluted with 100 ml of water, adjusted to pH 9.2 with concentrated aqueous ammonia and extracted with chloroform. Some unconverted 14-hydroxydihydronormorphinone was insoluble and was removed at this stage. The chloroform solution was concentrated and the residue crystallized from methanol chloroform, melting point approx. 151°C. <R>n part of the base was further purified as the hydrochloride salt, melting point 219°-222°C, from methanol-acetone.
fin porsjon på 6.15 g av basen, N-propyl-14-hydroksydihydronormorfinon, ble redusert med 1.1 g natriumborhydrid i etanol ved hjelp av metoden i eksempel 4 (a). Den resulterende base smeltet ved 234°-236°C. Den ble omdannet til hydrokloridsaltet, smeltepunkt 28l°-282°C, ved omkrystallisering fra metanol-aceton. fine portion of 6.15 g of the base, N-propyl-14-hydroxydihydronormorphinone, was reduced with 1.1 g of sodium borohydride in ethanol by the method of Example 4 (a). The resulting base melted at 234°-236°C. It was converted to the hydrochloride salt, mp 281°-282°C, by recrystallization from methanol-acetone.
