Description
Verfahren zur Herstellung neuer Polypeptide
Es ist bekannt, dass das Tetracosapeptid der Formel
L-Seryl-L-tyrosyl-L-seryl-L-methionyl-L-glutamyl-
L-histidyl-L-phenylalanyl-L-arginyl-L tryptophyl-glycyl-L-lysyl-L-prolyl-L-valyl- glycyl-L-lysyl-L-lysyl-L-arginyl-L-arginyl-L- prolyl-L-valyl-L-lysyl-L-valyl-L-tyrosyl-
L-prolin sowie die entsprechende Verbindung, die statt des Glutamylrestes den Rest des Glutamins aufweist, die Wirkung des natürlichen Adrenocoitcotropins (ACTH) hat.
Das natürliche Hormon, wie auch das oben genannte synthetische Tetracosapeptid enthalten ausschliesslich optisch aktive Aminosäuren der L-Form. Es wurde nun überraschenderweise gefunden, dass Tetracosapeptide der oben genannten Aminosäurezusammensetzung, in welchen die erste Aminosäure (Serin), D- oder D,L-Konfiguration hat, eine bessere adrenocorticotrope Wirkung als das nur LÁminosäuren aufweisende Tetracosapeptid besitzen.
Gegenstand der vorliegenden Erfindung ist daher ein Verfahren zur Herstellung des Tetracosapeptids der Formel
D-Seryl-L-tyrosyl-L-seryl-L-methionyl-L-glutamyl L-histidyl-L-phenylalanyl-L-arginyl-L- tryptophyl-glycyl-L-lysyl-L-prolyl-L-valyl glycyl-L-lysyl-L-lysyl-L-arginyl-Larginyl-L- prolyl-L-valyl-L-lysyl-L-valyl-L-tyrosyl
L-prolin, in der die erste Aminosäure D- oder D,L-Konfiguration hat, sowie der entsprechenden Verbindung, welche statt des Glutamylrestes den Rest des Glutamins aufweist, ferner von Säureadditionssalzen und deren Verwendung zur Herstellung von Komplexen der genannten Peptide mit komplexbildenden Metallen, wie Kupfer, Kobalt, und insbesondere Zink, oder schwerlöslichen Salzen oder Hydroxyden dieser Metalle, vor allem Zinkphosphat, Zinkpyrophosphat, Zinkhydroxyd und Zinkcarbonat.
Die bei einem pH von 7-8 in wässriger Lösung ausfallenden, schwerlöslichen Komplexe enthalten das Peptid chemisch gebunden an die schwerlösliche Metallverbindung, z. B. an Zinkphosphat, vgl. Schweizer Patent Nr. 467 073.
Die neuen Verbindungen haben eine hohe adrenocorticotrope Wirksamkeit und sollen in der Human- und Veterinärmedizin an Stelle des natürlichen Hormons verwendet werden.
Die neuen Tetracosapeptide werden erfindungsgemäss erhalten, wenn man die Aminosäuren D-Serin (oder D,L-Serin), L-Tyrosin, L-Serin, L-Methionin, L-Glutaminsäure (oder L-Glutamin), L-Histidin, L-Phenylalanin, L-Arginin, L-Tryptophan, Glycin, L-Lysin, L Prolin, L-Valin, Glycin, L-Lysin, L-Lysin, LArginin, L-Arginin, L-Prolin, L-Valin, L-Lysin, L-Valin, L Tyrosin, L-Prolin in der angegebenen Reihenfolge unter intermediärem Schutz der Amino- bzw. Carboxylgruppen miteinander vereinigt. Die Aminosäuren werden in der erwähnten Reihenfolge einzeln oder nach vorheriger Bildung kleinerer Peptideinheiten verknüpft. Beispielsweise kann man eines der Aminosäure- bzw. Peptidmoleküle in Form eines Esters mit einem weiteren Aminosäure- bzw.
Peptidmolekül, das eine geschützte Aminogruppe enthält, in Gegenwart eines Kondensationsmittels, wie eines Carbodiimids oder eines Phosphorigsäureesterhalogenids, verknüpfen, oder man kann mit dem Aminosäure- bzw. Peptidester mit freier Aminogruppe eine Aminosäure bzw. ein Peptid mit aktivierter Carboxylgruppe (und geschützter Aminogruppe), z. B.
ein Säurehalogenid, -azid, -anhydrid, -imidazolid, -isoxazolid (z. B. aus N-Athyl-5-phenyl-isoxazolium-3'-sul- fonat, s. Woodward et al., J. Am. Chem. Soc. 89, 1011 [1961]), oder einen aktivierten Ester, wie Cyanmethylester oder Carboxymethylthiolester, umsetzen. Umgekehrt kann auch eine Aminosäure bzw. ein Peptid mit freier Carboxylgruppe (und geschützter Aminogruppe) mit einer Aminosäure bzw. einem Peptid mit aktivierter Aminogruppe (und geschützter Carboxylgruppe), z. B.
einem Phosphitamid, zur Reaktion gebracht werden.
An der Reaktion nicht beteiligte, freie, funktionelle Gruppen werden zweckmässigerweise geschützt, insbe sondere mittels durch Hydrolyse oder Reduktion leicht abspaltbarer Reste, die Carboxylgruppe vorzugsweise durch Veresterung, z. B. mit Methanol, tert.-Butanol, Benzylalkohol, p-Nitrobenzylalkohol, die Aminogruppe beispielsweise durch Einführung des Tosyl-, Tritylrestes oder der Carbobenzoxygruppe oder farbiger Schutzgruppen, wie der p-Phenylazo-benzyloxycarbonylgruppe und der p-(p'-Methoxyphenylazo)-benzyloxycarbonyl gruppe, oder insbesondere des tert.-Butyloxycarbonyl- restes.
Zum Schutz der Aminogruppe in der Guanidogruppierung des Arginins ist die Nitrogruppe geeignet; die genannte Aminogruppe des Arginins muss aber bei der Reaktion nicht notwendig geschützt werden. Die Iminogruppe des Histidins kann vorteilhaft durch den Benzyl- oder Tritylrest geschützt werden.
Die Umwandlung einer geschützten Amino- oder Iminogruppe in eine freie Gruppe sowie die tSberfüh- rung einer funktionell abgewandelten Carboxylgruppe in eine freie Carboxylgruppe im Verlaufe des Verfahrens erfolgt nach an sich bekannten Methoden durch Behandlung mit hydrolysierenden bzw. reduzierenden Mitteln.
Vorteilhaft kondensiert man das Dekapeptid der Formel
L-Seryl-L-tyrosyl-L-seryl-L-methionyl-L-glutamyl (oder glutaminyl-)-L-histidyl-L-phenylalanyl
L-arginyl-L-tryptophyl-glycin, in dem die a-Aminogruppe des Seryls und gegebenenfalls die y-Carboxylgruppe des Glutamyls geschützt sind, in Gegenwart eines Carbodiimids mit einem Ester des Tetradecapeptids der Formel
L-Lysyl-L-prolyl-L-valyl-glycyl-L-lysyl-L-lysyl-L arginyl-L-arginyl-L-prolyl-L-valyl-L-lysyl-L valyl-L-tyrosyl-L-prolin, in dem die e-Aminogruppen des Lysyls geschützt sind.
Als Schutzgruppen für die a-Aminogruppe des Seryls und die Aminogruppen des Lysyls verwendet man vor- zugsweise die tert.-Butyloxycarbonylgruppe (B OC); die df^-Carboxylgruppe des Glutamyls und die Endcarboxylgruppe des Prolins werden vorteilhaft durch die tert. - Butylestergruppe geschützt.
Das genannte Tetradecapeptid kann beispielsweise nach den in der deutschen Patentschrift Nr. 1196 666 oder Nr. 1 214242 beschriebenen Verfahren hergestellt werden. Das Dekapeptid kann analog dem im Schweizer Patent Nr. 408 948 oder in den deutschen Patenten Nr. 1 212981 oder Nr. 1 210 877 beschriebenen Dekapeptid hergestellt werden. Man kann auch die Iminogruppe des Histidins durch den Benzyl- oder Tritylrest schützen, wie im Schweizer Patent Nr. 409 992 oder im französischen Patent Nr. 85 518 gezeigt, und das so geschützte Dekapeptidderivat mit dem Tetradekapeptidester kondensieren.
Ferner kann man auch vorteilhaft das Tetrapeptid tert.-Butyloxycarbonyl D-seryl-L-tyrosyl-L-seryl-L-methionrn mit dem Eikosapeptidester L-Glutamyl-(oder Glutaminyl-)L-histidyl-L phenylalanyl-Larginyl-L-tryptophyl-glycyl-L- lysyl-L-prolyl-L-valyl-glycyl-L-lysyl-Llysyl-L arginyl-L-arginyl-L-prolyl-L-valyl-L-lysyl-L valyl-L-tyrosyl-L-prolinester, in dem die E-Aminogruppen der Lysinreste durch die tert . -Butyloxycarbonylgruppe und die Carboxylgruppen des Prolin- und gegebenenfalls Glutaminsäurerestes durch die tert.-Butylestergruppe geschützt sind, kondensieren, beispielsweise nach der Azidmethode, wie im deutschen Patent Nr. 1196666 (Case 4823) beschrieben.
Der Eikosapeptidester mit Glutaminsäure als erster Aminosäure wird z. B. erhalten, wenn man Carbobenzoxy (i,-tert.-butyl) zL-glutamyl-L-histidyl-L-phenylalanyl-
L-arginyl-L-tryptophyl-glycin mit dem Tritosylat des Tetradekapeptidderivates E-tert. -Butyl-oxycarbonyl-L-lysyl-L-prolyl-L- valyl-glycyl-tert. -butyloxycarbonyl-Llysyl-tert . butyloxycarbonyl-L-lysyl-L-arginyl-L-arginyl
L-prolyl-L-valyl-tert.-butyloxycarbonyl-L lysyl-L-valyl-L-tyrosyl-L-prolin-tert.-butylester kondensiert und die Carbobenzoxygruppe hydrogenolytisch in Gegenwart von Eisessig und Palladiumkohle abspaltet.
Je nach der Arbeitsweise erhält man die neuen Verbindungen in Form von Basen oder ihren Salzen. Aus den Salzen können in an sich bekannter Weise die Basen gewonnen werden. Von letzteren wiederum lassen sich durch Umsetzung mit Säuren Salze gewinnen, wie z. B.
solche mit anorganischen Säuren, wie Halogenwasserstoffsäuren, beispielsweise Salzsäure oder Bromwasserstoffsäure, Perchlorsäure, Salpetersäure oder Thiocyansäure, Schwefel- oder Phosphorsäuren, oder organischen Säuren, wie Ameisensäure, Essigsäure, Propionsäure, Glykolsäure, Milchsäure, Brenztraubensäure, Oxalsäure, Nijialonsäure, Bernsteinsäure, Maleinsäure, Fumarsäure, Apfelsäure, Weinsäure, Zitronensäure, Ascorbinsäure, Hydroxymaleinsäure, Dihydroxymaleins äure, Benzoesäure, Phenylessigsäure, 4-Aminobenzoes äure, 4-Hydroxybenzoesäure, Anthranilsäure, Zimtsäure, Mandelsäure, Salicylsäure, 4-Amino-salicylsäure, 2-Phenoxybenzoesäure, 2-Acetoxybenzoesäure, Methansulfonsäure, Äthansulfons äure, Hydroxyäthansulfonsäure, Benzolsulfonsäure, p-Toluolsulfonsäure,
Naphthalinsulfonsäure oder Sulfanilsäure.
Die verfahrensgemäss erhaltenen Tetrakosapeptide können in Form von pharmazeutischen Präparaten Verwendung finden. Diese enthalten die Peptide in Mischung mit einem für die enterale oder parenterale Applikation geeigneten pharmazeutischen, organischen oder anorganischen Trägermaterial.
Die neuen Tetracosapeptide können in analoger Weise wie die nur L-Konfiguration aufweisenden Tetracosapeptide in Kompiexverbindungen übergeführt werden. So kann man insbesondere Zinkphosphat-, Zinkhydroxyd- und Zinkcarbonatkomplexe oder nach dem in der schweizerischen Patentschrift Nr. 490 337 beschriebenen Verfahren Zinkpyrophosphatkomplexe herstellen. Man erhält diese Komplexe, indem man eine saure wässrige Lösung, welche das Peptid und ein wasserlösliches Zinksalz enthält, mit einem Alkalimetallhydroxyd, -phosphat oder -pyrophosphat umsetzt und das pH auf 7-8 einstellt.
Die Erfindung wird im folgenden Beispiel beschrieben. Die Temperaturen sind in Celsiusgraden angegeben.

Anschliessend werden 11,1 g (0,11 Mol) Triäthylamin in 100 ml Methanol unter Rühren bei 400 innert 4 Stunden zugetropft. Nach weiterem Rühren während 2 Stunden bei 400 und über Nacht bei Zimmertemperatur wird die Reaktionslösung durch Zugabe von 2n Salzsäure auf pH 6-7 gestellt und darauf im Vakuum bei 300 von Methanol befreit. Die wässrige Lösung wird mit Essigester überschichtet und bei 0 unter Rühren mit konz. Salzsäure auf pH 1-2 gestellt. Die Essigesterphase wird rasch abgetrennt, mehrmals mit gesättigter Natriumchloridlösung gewaschen, getrocknet und im Vakuum eingedampft.

Die Lösung wird auf -5 gekühlt, unter Rühren mit einer Lösung von 4,53 g (22 mMol) Dicyclohexylcarbodiimid in 10 ml Acetonitril versetzt und eine Stunde bei -5 und über Nacht bei 0 gerührt. Nach Zugabe von 0,15 ml Eisessig wird das Reaktionsgemisch weitere 30 Min. bei 0 gerührt, der ausgeschiedene Dicyclohexyl harnstoff abfiltriert und das Filtrat bei 0,1 mm Hg eingedampft.
Der Rückstand wird in Essigester aufgenommen, die Lösung bei 0 mit ln Salzsäure, 1n Natriumbicarbonat und Wasser gewaschen, getrocknet und im Vakuum eingedampft. Der Rückstand verfestigt sich beim Verreiben mit Äther; nach Umkristallisieren aus Methanol-Äther: 9,1 g (76, F. 152-1550; [a]D= -7,00 + 10 (c = 0,9 in Methanol). Die Substanz zeigt im Dünnschichtchromatogramm folgende Rf-Werte: Rf = 0,29 in Chloroform + Methanol (9:1); Rf4s = 0,78; Rfioo = 0,85.

Eine Lösung von 12 g (20 mMol) tert.-Butyloxycarbonyl - D -seryl-L-tyrosyl-L-seryl-L-methionin-methyl- ester in 50 ml Methanol wird mit 5 ml (0,1 Mol) Hydrazinhydrat versetzt und bei Zimmertemperatur stehen gelassen. Nach 3 Stunden wird das ausgeschiedene kristalline Hydrazid abfiltriert und mit Wasser und Äthanol gewaschen: 9,82 g (82%), F. 148-152 ; umkristallisiert aus Methanol: F. 150-1530; [a]2D=-6,3 + 10 (c = 1 in Methanol).

1,43 g (2,4 mMol) tert.-Butyloxycarbonyl-D-seryl-L- tyrosyl-L-seryl-L-methionin-hydrazid werden bei - 100 in 15 ml Dimethylformamid aufgeschlämmt und bei dieser Temperatur mit 1,58 ml eiskalter 6n Salzsäure versetzt. Hierauf tropft man bei -XO 0,5 ml eiskalte 5n Natriumnitritlösung dazu und lässt 25 Min. bei -5 bis 80 reagieren. Gleichzeitig werden 1,65 g y-tert.-Butyl-L- glutamyl-L-histidyl-L-phenylalanyl-L-arginyl - L - tryptophylglycin (1,9 mMol), in 5 ml warmem Dimethylformamid gelöst, auf -100 gekühlt und mit 1,85 ml Triäthylamin versetzt.
Bei -150 trägt man die eiskalte Lösung des BOC-Tetrapeptidazides ein, rührt noch 1 Stunde bei -100 und lässt über Nacht bei 0 weiterreagieren. Aus der Reaktionslösung scheidet sich wenig anorganisches Salz aus. Dieses wird durch Filtration abgetrennt und die resultierende Lösung am Hochvakuum auf ein kleines Volumen eingeengt. Das rohe amorphe BOC-Dekapeptid wird mit 100 ml 2n Ammoniumhydroxydlösung ausgefällt, abgenutscht und mit Wasser neutral gewaschen.
Nach dem Trocknen erhält man 1,88 g rohes DekaPep- tidderivat. Die Kristallisation aus 50 ml 90 %igem Methanol gibt 1,2 g reines BOC-Dekapeptid. F. 2080 (Zers.).

Process for the production of new polypeptides
It is known that the tetracosapeptide of the formula
L-Seryl-L-tyrosyl-L-seryl-L-methionyl-L-glutamyl-
L-histidyl-L-phenylalanyl-L-arginyl-L tryptophyl-glycyl-L-lysyl-L-prolyl-L-valyl-glycyl-L-lysyl-L-lysyl-L-arginyl-L-arginyl-L-prolyl -L-valyl-L-lysyl-L-valyl-L-tyrosyl-
L-proline and the corresponding compound, which has the remainder of glutamine instead of the glutamyl residue, has the effect of natural adrenocoitcotropin (ACTH).
The natural hormone, as well as the synthetic tetracosapeptide mentioned above, contain only optically active amino acids of the L-form. It has now surprisingly been found that tetracosapeptides of the above-mentioned amino acid composition, in which the first amino acid (serine) has a D or D, L configuration, have a better adrenocorticotropic effect than the tetracosapeptide, which only has lamino acids.
The present invention therefore relates to a process for the preparation of the tetracosapeptide of the formula
D-Seryl-L-tyrosyl-L-seryl-L-methionyl-L-glutamyl L-histidyl-L-phenylalanyl-L-arginyl-L-tryptophyl-glycyl-L-lysyl-L-prolyl-L-valyl glycyl- L-lysyl-L-lysyl-L-arginyl-larginyl-L-prolyl-L-valyl-L-lysyl-L-valyl-L-tyrosyl
L-proline, in which the first amino acid has the D or D, L configuration, and the corresponding compound which has the remainder of glutamine instead of the glutamyl residue, and also acid addition salts and their use for the production of complexes of the peptides mentioned with complex-forming metals such as copper, cobalt, and in particular zinc, or sparingly soluble salts or hydroxides of these metals, especially zinc phosphate, zinc pyrophosphate, zinc hydroxide and zinc carbonate.
The sparingly soluble complexes which precipitate in aqueous solution at a pH of 7-8 contain the peptide chemically bound to the sparingly soluble metal compound, e.g. B. zinc phosphate, cf. Swiss Patent No. 467 073.
The new compounds have a high adrenocorticotropic activity and are to be used in human and veterinary medicine instead of the natural hormone.
The new tetracosapeptides are obtained according to the invention if the amino acids D-serine (or D, L-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, LArginine, L-Arginine, L-Proline, L-Valine, L- Lysine, L-valine, L tyrosine, L-proline combined with one another in the specified order with intermediate protection of the amino or carboxyl groups. The amino acids are linked individually in the order mentioned or after forming smaller peptide units beforehand. For example, one of the amino acid or peptide molecules can be in the form of an ester with another amino acid or peptide.
A peptide molecule containing a protected amino group in the presence of a condensation agent such as a carbodiimide or a phosphorous acid ester halide, or an amino acid or a peptide with an activated carboxyl group (and protected amino group) can be used with the amino acid or peptide ester with a free amino group, z. B.
an acid halide, azide, anhydride, imidazolide, isoxazolide (e.g. from N-ethyl-5-phenyl-isoxazolium-3'-sulfonate, see Woodward et al., J. Am. Chem. Soc. 89, 1011 [1961]), or an activated ester such as cyanomethyl ester or carboxymethyl thiol ester. Conversely, an amino acid or a peptide with a free carboxyl group (and a protected amino group) with an amino acid or a peptide with an activated amino group (and a protected carboxyl group), e.g. B.
a phosphite amide to react.
Free functional groups not involved in the reaction are expediently protected, in particular by means of radicals which can be easily split off by hydrolysis or reduction, the carboxyl group preferably by esterification, e.g. B. with methanol, tert-butanol, benzyl alcohol, p-nitrobenzyl alcohol, the amino group, for example by introducing the tosyl, trityl or carbobenzoxy group or colored protective groups such as the p-phenylazo-benzyloxycarbonyl group and the p- (p'-methoxyphenylazo) -benzyloxycarbonyl group, or in particular of the tert-butyloxycarbonyl radical.
The nitro group is suitable for protecting the amino group in the guanido grouping of arginine; However, the said amino group of arginine does not necessarily have to be protected during the reaction. The imino group of the histidine can advantageously be protected by the benzyl or trityl radical.
The conversion of a protected amino or imino group into a free group and the conversion of a functionally modified carboxyl group into a free carboxyl group in the course of the process takes place according to methods known per se by treatment with hydrolyzing or reducing agents.
The decapeptide of the formula is advantageously condensed
L-Seryl-L-tyrosyl-L-seryl-L-methionyl-L-glutamyl (or glutaminyl-) - L-histidyl-L-phenylalanyl
L-arginyl-L-tryptophyl-glycine, in which the α-amino group of seryl and optionally the γ-carboxyl group of glutamyl are protected, in the presence of a carbodiimide with an ester of the tetradecapeptide of the formula
L-Lysyl-L-prolyl-L-valyl-glycyl-L-lysyl-L-lysyl-L arginyl-L-arginyl-L-prolyl-L-valyl-L-lysyl-L valyl-L-tyrosyl-L- proline, in which the e-amino groups of the lysyl are protected.
The tert-butyloxycarbonyl group (B OC) is preferably used as protective groups for the a-amino group of seryl and the amino groups of lysyl; the df ^ -carboxyl group of glutamyl and the terminal carboxyl group of proline are advantageous by the tert. - Butyl ester group protected.
Said tetradecapeptide can be produced, for example, by the processes described in German patent specification No. 1196 666 or No. 1 214242. The decapeptide can be prepared analogously to the decapeptide described in Swiss Patent No. 408 948 or in German Patent No. 1,212,981 or No. 1,210,877. The imino group of the histidine can also be protected by the benzyl or trityl residue, as shown in Swiss Patent No. 409 992 or in French Patent No. 85 518, and the decapeptide derivative thus protected can be condensed with the tetradecapeptide ester.
Furthermore, the tetrapeptide tert-butyloxycarbonyl D-seryl-L-tyrosyl-L-seryl-L-methione with the eicosapeptide ester L-glutamyl- (or glutaminyl-) L-histidyl-L-phenylalanyl-larginyl-L-tryptophyl can also advantageously be used -glycyl-L-lysyl-L-prolyl-L-valyl-glycyl-L-lysyl-Llysyl-L arginyl-L-arginyl-L-prolyl-L-valyl-L-lysyl-L valyl-L-tyrosyl-L -proline ester, in which the E-amino groups of the lysine residues through the tert. -Butyloxycarbonylgruppe and the carboxyl groups of the proline and optionally glutamic acid residues are protected by the tert-butyl ester group, condense, for example by the azide method, as described in German Patent No. 1196666 (Case 4823).
The eikosapeptide ester with glutamic acid as the first amino acid is z. B. obtained if you carbobenzoxy (i, -tert.-butyl) zL-glutamyl-L-histidyl-L-phenylalanyl-
L-arginyl-L-tryptophyl-glycine with the tritosylate of the tetradecapeptide derivative E-tert. -Butyl-oxycarbonyl-L-lysyl-L-prolyl-L-valyl-glycyl-tert. -butyloxycarbonyl-Llysyl-tert. butyloxycarbonyl-L-lysyl-L-arginyl-L-arginyl
L-prolyl-L-valyl-tert.-butyloxycarbonyl-L lysyl-L-valyl-L-tyrosyl-L-proline tert.-butyl ester condensed and the carbobenzoxy group was split off hydrogenolytically in the presence of glacial acetic acid and palladium carbon.
Depending on the procedure, the new compounds are obtained in the form of bases or their salts. The bases can be obtained from the salts in a manner known per se. From the latter, in turn, salts can be obtained by reaction with acids, such as. B.
those with inorganic acids, such as hydrohalic acids, for example hydrochloric acid or hydrobromic acid, perchloric acid, nitric acid or thiocyanic acid, sulfuric or phosphoric acids, or organic acids, such as formic acid, acetic acid, propionic acid, glycolic acid, lactic acid, pyruvic acid, oxalic acid, nijialonic acid, succinic acid Acid, malic acid, tartaric acid, citric acid, ascorbic acid, hydroxymaleic acid, dihydroxymaleic acid, benzoic acid, phenylacetic acid, 4-aminobenzoic acid, 4-hydroxybenzoic acid, anthranilic acid, cinnamic acid, mandelic acid, salicylic acid, 4-amino-salicylic acid, 2-phenoxybenzoic acid, 2-amino-salicylic acid, acetic acid, 4-aminosulfoic acid , Ethanesulfonic acid, hydroxyethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid,
Naphthalenesulfonic acid or sulfanilic acid.
The tetrakosapeptides obtained according to the method can be used in the form of pharmaceutical preparations. These contain the peptides in a mixture with a pharmaceutical, organic or inorganic carrier material suitable for enteral or parenteral administration.
The new tetracosapeptides can be converted into complex compounds in a manner analogous to the tetracosapeptides having only the L configuration. In particular, zinc phosphate, zinc hydroxide and zinc carbonate complexes or zinc pyrophosphate complexes can be produced by the process described in Swiss Patent No. 490 337. These complexes are obtained by reacting an acidic aqueous solution containing the peptide and a water-soluble zinc salt with an alkali metal hydroxide, phosphate or pyrophosphate and adjusting the pH to 7-8.
