Tillegg til patent nr. 124.831Addendum to patent no. 124,831
I patent nr. 124.831 er det beskrevet peptider somIn patent no. 124,831 peptides are described which
utmerker seg ved en forsterket ACTH-virkning og som adskiller seg fra de kjente peptider med ACTH-virkning ved at de ved aminoenden som første a-aminosyre har en D-aminosyre. are distinguished by an enhanced ACTH effect and which differ from the known peptides with ACTH effect in that they have a D-amino acid at the amino end as the first α-amino acid.
Som peptid med meget god ACTH-virkning er det iAs a peptide with a very good ACTH effect, it is i

lettere enn D-Ser -3 -corticotropin, •fordi det ikke inneholder argininrestene i stillingene 17,18, som på grunn av guanidinogruppene i sidekjeden vanskeliggjør peptidets fremstilling. easier than D-Ser -3 -corticotropin, •because it does not contain the arginine residues in positions 17,18, which, due to the guanidino groups in the side chain, make the peptide's production difficult.
Oppfinnelsen vedrører altså en fremgangsmåte til fremstilling av nye peptider med øket og/eller forlenget ACTH-virkning, og med formel D-seryl-L-tyrosyl-L-seryl-L-metionyl-L-glutamyl (eller L-glutaminyl)-L-histidyl-L-fenylalanyl-L-arginyl-L-tryptofyl-glycyl-L-lysyl-L-propyl-L-valyl-glycyl-L-lysyl-L-lysyl-L-lysyl-L-lysyl-L-prolyl-L-valyl-L-lysyl-L-valyl-L-tyrosyl-L-prolin eller deres C-terminale amider og deres syreaddisjonssalter og komplekser. The invention thus relates to a method for the production of new peptides with increased and/or prolonged ACTH action, and with the formula D-seryl-L-tyrosyl-L-seryl-L-methionyl-L-glutamyl (or L-glutaminyl)-L -histidyl-L-phenylalanyl-L-arginyl-L-tryptophyll-glycyl-L-lysyl-L-propyl-L-valyl-glycyl-L-lysyl-L-lysyl-L-lysyl-L-lysyl-L-prolyl -L-valyl-L-lysyl-L-valyl-L-tyrosyl-L-proline or their C-terminal amides and their acid addition salts and complexes.
Som syreaddisjonssalter skal det spesielt nevnes salter av terapeutisk anvendbare syrer, -som saltsyre, eddiksyre, fremfor alt imidlertid tungtoppløselige salter, som sulfater, fosfater eller sulfonater. As acid addition salts, special mention must be made of salts of therapeutically applicable acids, such as hydrochloric acid, acetic acid, above all, however, poorly soluble salts, such as sulfates, phosphates or sulfonates.
Med komplekser er det å forstå de komplekslignende i deres struktur ennu ikke avklarede forbindelser som oppstår ved tilsetning av visse uorganiske eller organiske stoffer til adrenocor-ticotrop virksomme peptider og fremfor alt de som gir dem en forlenget virkning. Slike uorganiske stoffer er forbindelser som av-leder seg fra metaller som kalsium, magnesium, aluminium, kobolt og spesielt fra sink, fremfor alt tungtoppløselige salter, som fosfater og pyrofosfater, såvel som hydroksyder av disse metaller. Organiske stoffer som bevirker en forlengelse av virkningen, er eksempelvis ikke antigene gelatiner, f.eks. oksypolygelatiner, polyvinylpyrrolidon og karboksymetylcellulose, videre sulfonsyre- eller fosforsyreestere av alginsyre, dextrin, polyfenoler og polyalkoholer, fremfor alt polyfloretinfosfat og fytinsyre, såvel som polymerisater og kopolymerisater av aminosyrer, f.eks. protamin og spesielt av aminosyrer som har en overveiende del av sure a-aminosyrer, som glutaminsyre eller asparaginsyre. Complexes are to be understood the complex-like in their structure not yet clarified compounds that arise from the addition of certain inorganic or organic substances to adrenocorticotropic active peptides and above all those that give them a prolonged effect. Such inorganic substances are compounds which derive from metals such as calcium, magnesium, aluminium, cobalt and especially from zinc, above all sparingly soluble salts, such as phosphates and pyrophosphates, as well as hydroxides of these metals. Organic substances which cause a prolongation of the effect are, for example, non-antigenic gelatins, e.g. oxypolygelatins, polyvinylpyrrolidone and carboxymethylcellulose, further sulphonic acid or phosphoric acid esters of alginic acid, dextrin, polyphenols and polyalcohols, above all polyphloretin phosphate and phytic acid, as well as polymers and copolymers of amino acids, e.g. protamine and especially of amino acids that have a predominant proportion of acidic α-amino acids, such as glutamic acid or aspartic acid.
De nye forbindelser har som allerede nevnt en ves-entlig sterkere ACTH-aktivitet enn de tilsvarende forbindelser med L-konfigurasjon ved første'aminosyre. De skal følgelig anvendes i human- og veterinærmedisin, f.eks. i stedet for det naturlige hormon. As already mentioned, the new compounds have a substantially stronger ACTH activity than the corresponding compounds with L-configuration at the first amino acid. They must therefore be used in human and veterinary medicine, e.g. instead of the natural hormone.
Fremgangsmåten ifølge oppfinnelsen erkarakterisertved at aminosyrene D-serin, L-tyrosin, L-serin, L-metionin, L-glutaminsyre (eller L-glutamin), L-histidin, L-fenylalanin, L-arginin, L-tryptofan, glycin, L-lysin, L-prolin, L-valin, glycin, L-lysin, L-lysin, L-lysin, L-lysin, L-prolin, L-valin, L-lysin, L-valin,L-tyrosin, L-prolin eller L-prolinamid og/eller peptidbruddstykker som inneholder disse aminosyrer i ønsket rekkefølge., eventuelt i form av reaktive derivater av aminosyrene og/eller peptidbrostykkene, kondenseres under anvendelse av innen peptidkjemien kjente metoder og under intermediær beskyttelse av reaktive grupper til det angitte peptid eller peptidamid, som deretter, hvis ønsket, overføres i terapeutisk anvendbare syreaddisjonssalter eller komplekser. The method according to the invention is characterized in that the amino acids D-serine, L-tyrosine, L-serine, L-methionine, L-glutamic acid (or L-glutamine), L-histidine, L-phenylalanine, L-arginine, L-tryptophan, glycine, L-lysine, L-proline, L-valine, glycine, L-lysine, L-lysine, L-lysine, L-lysine, L-proline, L-valine, L-lysine, L-valine, L-tyrosine, L-proline or L-prolinamide and/or peptide fragments containing these amino acids in the desired order, optionally in the form of reactive derivatives of the amino acids and/or peptide bridge fragments, are condensed using methods known in peptide chemistry and under intermediate protection of reactive groups to the indicated peptide or peptidamide, which are then, if desired, transferred into therapeutically useful acid addition salts or complexes.
Sammenknytningen av aminosyre- og/eller peptidenhet-ene foregår således at man omsetter en aminosyre eller et peptid med beskyttet a-aminogruppe og aktivert terminal karboksylgruppe med en aminosyre eller et peptid med frie a-aminogrupper og frie eller beskyttet, f.eks. forestret eller amidert terminal karboksylgruppe, eller at man omsetter en aminosyre eller et peptid med aktivert a-aminogruppe og beskyttet terminal karboksylgruppe med en aminosyre eller et peptid med fri terminal karboksylgruppe og beskyttet a-aminogruppe. Karboksylgruppen kan eksempelvis aktiveres ved overføring i et syrehalogenid, -azid, -anhydrid, -imidazolid, isoksazolid eller en aktivert ester, som cyanmetylester, karboksymetylester, p-nitro-fenylester, eller ved reaksjon ved hjelp av et karbodiimid (eventuelt under tilsetning av N-hydroksysuccinimid) eller N,N'-karbonyl-diimidazol, aminogruppen aktiviseres eksempelvis ved reaksjon med et fosfatamid. Som vanlige metoder kan det nevnes karbodiimidmetoden, azidmetoden, metoden av aktivert ester og anhydridmetoden. Det skal også fremheves den såkalte faststoffbæresyntesen, hvor peptidet opp-bygges fra karboksylenden, som er bundet esteraktig til en polymer, idet man påkondenserer aminosyrene i rekkefølge. The linking of the amino acid and/or peptide units takes place in such a way that one reacts an amino acid or a peptide with a protected α-amino group and activated terminal carboxyl group with an amino acid or a peptide with free α-amino groups and free or protected, e.g. esterified or amidated terminal carboxyl group, or that one reacts an amino acid or a peptide with an activated α-amino group and protected terminal carboxyl group with an amino acid or a peptide with a free terminal carboxyl group and protected α-amino group. The carboxyl group can, for example, be activated by transfer into an acid halide, -azide, -anhydride, -imidazolide, isoxazolide or an activated ester, such as cyanomethyl ester, carboxymethyl ester, p-nitro-phenyl ester, or by reaction using a carbodiimide (possibly with the addition of N -hydroxysuccinimide) or N,N'-carbonyl-diimidazole, the amino group is activated, for example, by reaction with a phosphatamide. Common methods include the carbodiimide method, the azide method, the activated ester method and the anhydride method. Emphasis should also be placed on the so-called solid carrier synthesis, where the peptide is built up from the carboxyl end, which is bound in an ester-like manner to a polymer, by condensing the amino acids in sequence.
I reaksjonen ikke deltagende, frie, funksjonelle grupper beskyttes spesielt ved hjelp av ved hydrolyse eller reduksjon lett avspaltbare rester, karboksylgruppen fortrinnsvis ved forestring, f.eks. med metanol, tert.-butanol, benzylalkohol, p-nitrogenzylalko-hol, eller amiddannelsen, aminogruppen eksempelvis ved innføring av tosyl-, trityl-, formyl-, trifluoracetyl-, o-nitrofenyl-sulfenyl-, ftalyl- eller karbobenzoksygruppen eller farvede beskyttelsesgrupper som p-fenyl-azo-benzyloksykarbonylgruppen eller p-(p'-metoksy-fenyl-azo)-benzyloksykarbonylgruppen, eller spesielt av tert.-butyloksykar-bonylresten. Til beskyttelsen av aminogruppen i argininets guanido-gruppering er nitrogruppen egnet; den nevnte aminogruppe av arginin må imidlertid ikke nødvendigvis beskyttes ved reaksjonen. Histidin-ets iminogruppe kan beskyttes ved hjelp av benzyl- eller tritylresten. Free functional groups not participating in the reaction are protected in particular by means of residues that can be easily split off by hydrolysis or reduction, the carboxyl group preferably by esterification, e.g. with methanol, tert.-butanol, benzyl alcohol, p-nitrogenyl alcohol, or the amide formation, the amino group, for example by introducing the tosyl, trityl, formyl, trifluoroacetyl, o-nitrophenyl-sulfenyl, phthalyl or carbobenzoxy group or colored protecting groups such as the p-phenyl-azo-benzyloxycarbonyl group or the p-(p'-methoxy-phenyl-azo)-benzyloxycarbonyl group, or especially of the tert-butyloxycarbonyl residue. For the protection of the amino group in the arginine's guanido grouping, the nitro group is suitable; however, the said amino group of arginine does not necessarily have to be protected in the reaction. The histidine's imino group can be protected by means of the benzyl or trityl residue.
Omdannelsen av en beskyttet amino- eller iminogruppe til en fri gruppe, såvel som overføringen av en funksjonell modifisert karboksylgruppe i en fri 'karboksylgruppe under fremgangsmåteforløpet foregår etter i og for seg kjente metoder ved behandling med hydro-lyserende resp. reduserende midler. The conversion of a protected amino or imino group into a free group, as well as the transfer of a functionally modified carboxyl group into a free carboxyl group during the course of the process takes place according to methods known per se by treatment with hydrolyzing resp. reducing agents.
En foretrukket fremgangsmåte består i at man kon-denserer de første 3 aminosyrer, f.eks. H-D-Ser-Tyr-OH-holdige tri-peptid (den forkortede skrivemåte refererer seg til L-aminc-syren, A preferred method consists in condensing the first 3 amino acids, e.g. H-D-Ser-Tyr-OH-containing tri-peptide (the abbreviated spelling refers to the L-aminc acid,
når D- ikke er spesielt betegnet), eller det dessuten den 4.aminosyreholdige tetrapeptid med heptapeptid, res. heksapeptid av følgende aminosyrer til aminosyre 10, fortrinnsvis etter azidmetoden, og deretter kondenseres dekapeptidet med tetradekapeptidet av aminosyre 11-24. Ved denne kondensasjon anvendes som koblingsmetode fortrinnsvis karbodiimidmetoden eller metoden av aktiverte estere, fremfor alt ved hjelp av p-nitrofenylesteren. I sistnevnte tilfelle behøver p-nitrofenylesteren av dekapeptidet ikke å isoleres som sådanne, men kan også dannes i selve kondensasjonstrinnet fra dekapeptid med fri karboksylgruppe p-nitrofenol og dicykloheksylkarbodiimid. Dekapeptidet foreligger altså som a-aminobeskyttet peptid med fri karboksylgruppe eller med en p-nitrofenylestergruppe. Tetradekapeptidet anvendes i form av en ester, fortrinnsvis av tert. butylester eller av w-amidet. De i peptidbruddstykkene som skal kondenseres, tilstede-værende sidekjeder-aminogrupper beskyttes fortrinnsvis ved tert.-butyloksykarbonylgruppen, sidekjedekarboksylgruppen ved tert.-butylestergruppen. Disse beskyttelsesgrupper kan avspaltes i siste trinn med trifluoreddiksyre. when D- is not specifically designated), or the 4th amino acid-containing tetrapeptide with heptapeptide, res. hexapeptide of the following amino acids to amino acid 10, preferably by the azide method, and then the decapeptide is condensed with the tetradecapeptide of amino acids 11-24. In this condensation, the coupling method is preferably the carbodiimide method or the method of activated esters, above all using the p-nitrophenyl ester. In the latter case, the p-nitrophenyl ester of the decapeptide does not need to be isolated as such, but can also be formed in the condensation step itself from the decapeptide with free carboxyl group p-nitrophenol and dicyclohexylcarbodiimide. The decapeptide is thus available as an α-amino-protected peptide with a free carboxyl group or with a p-nitrophenyl ester group. The tetradecapeptide is used in the form of an ester, preferably of tert. butyl ester or of the w-amide. The side chain amino groups present in the peptide fragments to be condensed are preferably protected by the tert-butyloxycarbonyl group, the side chain carboxyl group by the tert-butyl ester group. These protecting groups can be removed in the final step with trifluoroacetic acid.
Ifølge en ytterligere foretrukket fremgangsmåte kondenseres de første 4 aminosyreholdige tetrapeptider H-D-Ser-Tyr-Ser-Met-OH med eicosapeptidet av aminosyrene 5~24. Ved denne kondensasjon anvendes som koblingsmetode fortrinnsvis azidmetoden. Tetrapeptid-hydrazidets resp. -azidets a-aminogruppe beskyttes fortrinnsvis ved den tert. butyloksykarbonylgruppe. Eicosapeptidet kan foreligge som fritt peptid eller som ester, spesielt tert. butylester, eller som Pro 2k-amid. Også i Eicosapeptidet beskyttes sidekjede-aminogruppene fortrinnsvis ved tert.butyloksykarbonylgruppen, sidekjedekarboksylgruppen ved tert. butylestergruppen. According to a further preferred method, the first 4 amino acid-containing tetrapeptides H-D-Ser-Tyr-Ser-Met-OH are condensed with the eicosapeptide of amino acids 5~24. In this condensation, the azide method is preferably used as the coupling method. The tetrapeptide hydrazide's resp. -azide's α-amino group is preferably protected by the tert. butyloxycarbonyl group. The eicosa peptide can exist as a free peptide or as an ester, especially tert. butyl ester, or as Pro 2k-amide. Also in the Eicosapeptide, the side chain amino groups are preferably protected by the tert.butyloxycarbonyl group, the side chain carboxyl group by tert. the butyl ester group.
Etterat man ved kondensasjon av peptidbruddstykker har fått tetracosapeptid, hvis a-aminogruppe og sidekjede-aminogrupper er beskyttet med tert. butyloksykarbonylgruppe og dets endekarboksyl-gruppe og sidekjedekarbpksylgruppe med tert. butylestergruppen, kan alle disse beskyttelsesgrupper avspaltes samtidig ved sur hydrolyse, eksempelvis med trifluoreddiksyre. Foreligger endekarboksylgruppen ikke som tertbutylestergruppe, men som amidgruppe, så fåes peptidamider. Peptidhydrazider får man eksempelvis når man behandler et peptid med endeplasserte laverealkylestergrupper med hydrazinhydrat. After, by condensation of peptide fragments, tetracosapeptide has been obtained, whose α-amino group and side-chain amino groups are protected with tert. butyloxycarbonyl group and its terminal carboxyl group and side chain carboxyl group with tert. the butyl ester group, all these protecting groups can be removed simultaneously by acid hydrolysis, for example with trifluoroacetic acid. If the terminal carboxyl group is not present as a tert-butyl ester group, but as an amide group, then peptidamides are obtained. Peptide hydrazides are obtained, for example, when a peptide with terminally placed lower alkyl ester groups is treated with hydrazine hydrate.
Alt etter arbeidsmåte får man de nye forbindelserDepending on the way you work, you get the new connections
i form av baser eller deres salter. Fra saltene kan basene utvinnes på i og for seg kjent måte. Fra sistnevnte igjen lar det seg ved omsetning med syrer, som er egnet til dannelse av terapeutisk anvendbare salter utvinne salter som f.eks. slike med uorganiske syrer, in the form of bases or their salts. The bases can be extracted from the salts in a manner known per se. From the latter again, by reaction with acids, which are suitable for the formation of therapeutically usable salts, salts such as e.g. those with inorganic acids,
som halogenhydrogensyrer, eksempelvis saltsyre eller bromhydrogensyre, perklorsyre, salpetersyre eller tiocyansyre, svovel- eller fosforsyre, eller organiske syrer, som maursyre, eddiksyre, propionsyre, glykol-syre, melkesyre, pyrodruesyre, oksalsyre, malonsyre, ravsyre, malein-syre, fumarsyre, eplesyre, vinsyre, sitronsyre, ascorbinsyre, hydroksy-maleinsyre, dihydroksymaleinsyre, benzosyre, fenyleddiksyre, 4-amino-benzosyre, 4-hydroksybenzosyre, antranilsyre, kanelsyre, mandelsyre,; salicylsyre, 4-amino-salicylsyre, 2-fenoksybenzosyre, 2-acetoksy-benzosyre, metansulfonsyre, etansulfonsyre, hydroksyetansulfonsyre, benzolsulfonsyre, p-toluolsulfonsyre, naftalinsulfonsyre eller sul-fanilsyre. such as hydrohalic acids, for example hydrochloric or hydrobromic acid, perchloric acid, nitric acid or thiocyanic acid, sulfuric or phosphoric acid, or organic acids, such as formic acid, acetic acid, propionic acid, glycolic acid, lactic acid, pyruvic acid, oxalic acid, malonic acid, succinic acid, maleic acid, fumaric acid, malic acid, tartaric acid, citric acid, ascorbic acid, hydroxymaleic acid, dihydroxymaleic acid, benzoic acid, phenylacetic acid, 4-amino-benzoic acid, 4-hydroxybenzoic acid, anthranilic acid, cinnamic acid, mandelic acid,; salicylic acid, 4-amino-salicylic acid, 2-phenoxybenzoic acid, 2-acetoxy-benzoic acid, methanesulfonic acid, ethanesulfonic acid, hydroxyethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, naphthalenesulfonic acid or sulfanilic acid.
De peptider som kan fremstilles ved fremgangsmåten, kan finne anvendelse i form av farmasøytiske preparater. Disse inneholder peptidene i blanding med et for den enterale eller parenterale applikasjon egnede farmasøytiske, organiske eller uorganiske bære-materialer. For dette kommer det på tale slike stoffer som ikke reagerer med polypeptidene som f.eks. gelatiner, melkesukker, glukose, kokesalt, stivelse, magnesiumstearat, talk, planteoljer, benzylalko-holer, gummi, polyalkylenglykoler, vaselin, cholesterin eller andre kjente legemiddelbærere. De farmasøytiske preparater kan f.eks. foreligge som lyofilisat eller i flytende form som oppløsninger, suspen-sjoner eller emulsjoner. Enten er de sterilisert og/eller inneholder hjelpestoffer, som konserverings-, stabiliserings-, fukte- eller emulgeringsmiddel. De kan dessuten også inneholde andre terapeutisk verdifulle stoffer. The peptides that can be produced by the method can be used in the form of pharmaceutical preparations. These contain the peptides in mixture with a pharmaceutical, organic or inorganic carrier material suitable for enteral or parenteral application. This includes such substances that do not react with the polypeptides, such as e.g. gelatins, milk sugar, glucose, table salt, starch, magnesium stearate, talc, vegetable oils, benzyl alcohols, rubber, polyalkylene glycols, vaseline, cholesterol or other known drug carriers. The pharmaceutical preparations can e.g. available as a lyophilisate or in liquid form as solutions, suspensions or emulsions. They are either sterilized and/or contain auxiliary substances, such as preservatives, stabilisers, wetting agents or emulsifiers. They may also contain other therapeutically valuable substances.
Således kan man eksempelvis også kombinere dem med de i ACTH-terapien vanlige tilsetninger for å forlenge virkningen, Thus, for example, you can also combine them with the usual additives in ACTH therapy to prolong the effect,
som f.eks. oksypolygelatiner, polyfloretinfosfat, karboksymetylcellulose, eller åe ovennevnte tungt oppløselige metallforbindelser, spesielt fosfater, pyrofosfater eller hydroksyder av sink. like for example. oxypolygelatins, polyphloretin phosphate, carboxymethylcellulose, or the aforementioned sparingly soluble metal compounds, especially phosphates, pyrophosphates or hydroxides of zinc.
Videre kan man for å forlenge virkningen overføreFurthermore, in order to prolong the effect, it can be transferred
de nye peptider i deres komplekser med polymerisater eller kopolymerisater av aminosyrer, spesielt slike som har en overveiende del av sure a-aminosyrer, som glutaminsyre eller asparaginsyre av L-, D- eller D,L-konfigurasjonen. De nevnte polymerisater og kopolymerisater har i sidekjeden frie karboksylgrupper, mens den terminale karboksylgruppe kan foreligge i fri eller være modifisert funksjonell, f.eks. som estergruppe eller som en usubstituert eller ved hydrokarbonrester, fremfor alt lavere alkylgrupper, substituerte amidgruppe. Polymeri-satenes molekylvekt kan ligge mellom 1000 og 100.000, fortrinnsvis utgjør den 2000 - 15.000. Man anvender for preparatets fremstilling hensiktsmessig et vannoppløselig, fysiologisk tålbart salt, f.eks. natrium- eller ammoniumsalt, eller et salt med en organisk base, the new peptides in their complexes with polymers or copolymers of amino acids, especially those having a predominant part of acidic α-amino acids, such as glutamic acid or aspartic acid of the L-, D- or D,L configuration. The aforementioned polymers and copolymers have free carboxyl groups in the side chain, while the terminal carboxyl group can be free or be functionally modified, e.g. as an ester group or as an unsubstituted or, in the case of hydrocarbon residues, above all lower alkyl groups, substituted amide group. The molecular weight of the polymers can be between 1,000 and 100,000, preferably 2,000 - 15,000. A water-soluble, physiologically tolerable salt is suitably used for the preparation of the preparation, e.g. sodium or ammonium salt, or a salt with an organic base,
som trietylamin, procain, dibenzylamin, eller andre tertiære nitro-genbaser. such as triethylamine, procaine, dibenzylamine, or other tertiary nitrogen bases.
Polymerene er kjent eller kan fremstilles etter kjente metoder, eksempelvis'etter den av M. Idelson et al. J.Am. The polymers are known or can be prepared according to known methods, for example according to that of M. Idelson et al. J. Am.
Chem. Soc. 80, 4631 et seq. (1958) beskrevne fremgangsmåte. Således kan man f.eks. la glutaminsyre-a-karboksyanhydrid, -benzylester eller -tert.-butylester i dioksan reagere med ammoniakk eller et amin i et bestemt molforhold, f.eks. 100:1 (alt etter den ønskede poly-merisasjonsgrad), og etter avsluttet polymerisasjon avspalte beskyt-telsesgruppene, f.eks. benzyloksygruppene med bromhydrogeh i iseddik, den tertiære butyloksygruppe med trifluoreddiksyre. For fremstilling av polymere med enhetlig, definerte kjedelengder kan man oppbygge polymerene også ved syntese etter de i peptidkjemien kjente frem-gangsmåter (Carbodiimidmetoden, azidmetoden etc.). Chem. Soc. 80, 4631 et seq. (1958) described procedure. Thus, one can e.g. let glutamic acid α-carboxylic anhydride, -benzyl ester or -tert-butyl ester in dioxane react with ammonia or an amine in a specific molar ratio, e.g. 100:1 (according to the desired degree of polymerisation), and after the polymerisation is finished, split off the protective groups, e.g. the benzyloxy groups with bromohydrogeh in glacial acetic acid, the tertiary butyloxy group with trifluoroacetic acid. For the production of polymers with uniform, defined chain lengths, the polymers can also be built up by synthesis according to procedures known in peptide chemistry (the carbodiimide method, the azide method, etc.).
Konsentrasjonen av den polymere i de farmasøytiske preparater avhenger av det angjeldende salts oppløselighet og av vis-kositeten. Den polymere skal kunne foreligge i preparatene i oppløst form og være injiserbare. The concentration of the polymer in the pharmaceutical preparations depends on the solubility of the salt in question and on the viscosity. The polymer must be able to be present in the preparations in dissolved form and be injectable.
Konsentrasjonen av det adrenocorticotrope virksomme peptid velges således at preparatet eksempelvis har p. ml 10-50 I.E. The concentration of the adrenocorticotropic active peptide is chosen so that the preparation has, for example, per ml 10-50 I.E.

Oppløsningen inndampes deretter til ca. 2 ml, fortynnes med 20 ml vann, inndampes igjen og lyofiliseres til slutt. Man får trifluoracetatet av det frie tetra-kosapeptid, som for omdannelse i acetat oppløses i litt vann og filtreres gjennom en søyle (0 = 12,5 mm, lengde = 15 cm) av svakt basisk ioneutveksler (f. eks. Merck Nr. II) i acetatform. Eluatet konsentreres til ca. 3 ml, lyofiliseres og ettertørkes i høyvakuum ved 40°C. Man får 316 mg kromatografisk og elektroforetisk enhetlig acetat av 370 mg BOC-D-Ser-Tyr-Ser-Met-Glu(OtBu)-His-Phe-Arg-Try-Gly-Lys(BOC)-Pro-Val-Gly-Lys(BOC)-Lys-(BOC) -Lys(BOC)-Lys(BOC)-Pro-Val-Lys(BOC)-Val-Tyr-Pro-OtBu is dissolved in 7.4 ml of 90% triflucracetic acid and allowed to stand for 45 minutes at 25°C. The solution is then evaporated to approx. 2 ml, diluted with 20 ml of water, evaporated again and finally lyophilized. The trifluoroacetate is obtained from the free tetracosapeptide, which for conversion into acetate is dissolved in a little water and filtered through a column (0 = 12.5 mm, length = 15 cm) of weakly basic ion exchanger (e.g. Merck No. II ) in acetate form. The eluate is concentrated to approx. 3 ml, lyophilized and post-dried in high vacuum at 40°C. 316 mg of chromatographically and electrophoretically uniform acetate are obtained

Man hensetter den klare oppløsning i 24 timer ved 25°C og inndamper deretter til ca. 1/3 av det opprinnelige volum. Ved blanding med 200 ml vann faller det ut et oljeaktig bunnfall, som blir fast ved avkjøling og utdrivning og kan pulveriseres. Man suger fra på nutsch, vasker med vann og tørker råproduktet. Det renses ved engangs omkrystallisering fra metanol-iseddik-petroleter og har da et smeltepunkt på 118-119,5°C. The starting material can be prepared as follows: 1) Z.Lys(B0C)- Lys(B0C), NHNH2 10 g Z.Lys(B0C)-Lys(B0C).OCH^ (prepared from Z.Lys-(BOC)-OH + H.Lys(B0C)-OH (using dicyclohexylcarbodiimide) is dissolved in 160 ml of methanol and mixed with 7.8 ml of hydrazine hydrate. The clear solution is kept for 24 hours at 25°C and then evaporated to approx. 1/3 of the original volume. When mixed with 200 ml of water, an oily precipitate falls out, which solidifies on cooling and expulsion and can be pulverized. The nutsch is sucked off, washed with water and the raw product dried. It is purified by one-time recrystallization from methanol-glacial vinegar-petroleum ether and then has a melting point of 118-119.5°C.
