Description
- TECHNISCHES GEBIET
- Die Erfindung betrifft bestimmte Kohlenwasserstoffderivate, die polare Substituenten tragen, und ihre Verwendung bei der Inhibition retroviraler Proteasen, zum Beispiel bei der Behandlung von HIV-Virus-Infektionen, wie beispielsweise des Acquired Immune Deficiency Syndrome (AIDS).
- STAND DER TECHNIK
- Der humane Immundefizienz-Virus (HIV) ist ein pathogener Retrovirus, der AIDS und dessen verwandte Erkrankungen verursacht. Die Entwicklung einer antiviralen Chemotherapie gegen AIDS ist seit der Entdeckung des HIV der Gegenstand intensiver Forschungsanstrengung gewesen. (Für eine neuere Übersicht über molekulare Ziele für eine AIDS-Therapie siehe Mitsua et al., Science, 1990, S. 1533–1544). Die HIV-Proteasen (HIV PR) und Aspartyl-Proteasen wurden zuerst von Kramer et al. (Science 231, 1580 (1986)) als potentielles Ziel für eine AIDS-Therapie vorgeschlagen. Seit dieser Zeit ist die potentielle Verwendbarkeit von HIV-PR-Inhibitoren als wirksamen Mitteln bei der Behandlung von AIDS in weitem Maße anerkannt (für eine Übersicht der HIV PR als therapeutisches Ziel siehe Tomaselli et al., Chimica Oggi, Mai 1991, S. 6–27, und Huff, J. R., J. Med. Chem. 34, 2314–2327 (1991)). Von den klassischen Nachahmern des Übergangszustands für Aspartyl-Proteasen scheinen die Hydroxyethylen-, Dihydroxyethylen-, Hydroxyethylamin- und Phosphinsäureisostere die größte Affinität für HIV PR bereitzustellen. Es ist gezeigt worden, daß viele Inhibitoren von HIV PR eine antivirale Aktivität bei Konzentrationen im nanomolaren Bereich in den verschiedenen Zellsystemen haben, und sie sind als solche in der Patentliteratur beschrieben.
- AUFGABEN DER ERFINDUNG
- Es ist eine Aufgabe der vorliegenden Erfindung, Verbindungen bereitzustellen, die als Inhibitoren von retroviraler Protease verwendbar sind. Es ist eine andere Aufgabe der vorliegenden Erfindung, pharmazeutische Zusammensetzungen, die derartige Verbindungen umfassen, und die Verwendung derartiger Verbindungen für die Herstellung von Medikamenten bereitzustellen.
- ZUSAMMENFASSUNG DER ERFINDUNG
- Die Erfindung stellt Verbindungen bereit, welche als Inhibitoren retroviraler Proteasen, besonders Aspartyl-Proteasen und insbesondere HIV-Proteasen, verwendbar sind, und welche bei der Behandlung von Leiden, gekennzeichnet durch die unerwünschte Aktivität dieser Enzyme, insbesondere des Acquired Immune Deficiency Syndrome, wirksam sind.
- In der folgenden Beschreibung der Erfindung ist die Lehre von jeder der erwähnten Veröffentlichungen hier durch Bezugnahme einbezogen.
- Gemäß einer ersten Ausführungsform dieser Erfindung wird eine Verbindung bereitgestellt, ausgewählt aus der Gruppe, bestehend aus:
cis-1,6-3-t-Butoxycarbonyl-4-[(2S,3S)-2-phosphonooxy-3-(N-chinaldoyl-L-asparaginyl)amino-4-phenylbutyl]-3,4-diaza-bicyclo[4.4.0]decan;
cis-1,6-3-t-Butoxycarbonyl-4-[(2S,3S)-2-phosphitooxy-3-(N-chinaldoyl-L-asparaginyl)amino-4-phenylbutyl]-3,4-diaza-bicyclo[4.4.0]decan;
t-Butyl-3-isopropyl-3-[(2S,3S)-2-phosphonooxy-3-(N-chinaldoyl-L-asparaginyl)amino-4-phenylbutylcarbazat; und
t-Butyl-3-isopropyl-3-[(2S,3S)-2-phosphitooxy-3-(N-chinaldoyl-L-asparaginyl)amino-4-phenylbutylcarbazat. - Gemäß einer zweiten Ausführungsform dieser Erfindung wird eine pharmazeutische Zusammensetzung, umfassend eine wirksame Menge einer Verbindung der ersten Ausführungsform zusammen mit mindestens einem pharmazeutisch verträglichen Träger, Verdünnungsmittel, Hilfsstoff und/oder Adjuvans, bereitgestellt.
- Die Zusammensetzung der zweiten Ausführungsform kann für orale Verabreichung vorgesehen werden.
- Gemäß einer dritten Ausführungsform dieser Erfindung wird die Verwendung einer Verbindung gemäß der ersten Ausführungsform für die Herstellung eines Medikaments zur Inhibition einer retroviralen Protease bei einem Säuger mit Bedarf an einer solchen retroviralen Protease-Inhibition bereitgestellt.
- Die retrovirale Protease ist eine HIV-Protease. Das Medikament kann für orale Verabreichung vorgesehen werden.
- Gemäß einer vierten Ausführungsform dieser Erfindung wird die Verwendung einer Verbindung gemäß der ersten Ausführungsform zur Herstellung eines Medikaments zur Behandlung oder Prophylaxe des Acquired Immune Deficiency Syndrome bei einem Säuger mit Bedarf an einer solchen Behandlung bereitgestellt.
- Geeignete pharmazeutisch vernägliche Salze der Verbindung von den Verbindungen der ersten Ausführungsform sind, wo die Verbindung ein basisches Stickstoffatom enthält, Säureadditionssalze von pharmazeutisch verträglichen anorganischen Säuren, wie beispielsweise Chlorwasserstoff-, Schwefel-, Phosphor-, Salpeter-, Kohlen-, Bor-, Sulfamin-, Bromwasserstoff oder Jodwasserstoffsäure, oder mit pharmazeutisch verträglichen organischen Säuren, wie beispielsweise Essig-, Propion-, Butter-, Wein-, Malein-, Hydroxymalein-, Methylmalein-, Fumar-, Äpfel-, Citronen-, Milch-, Schleim-, Glucon-, Glucohepton-, Glucar-, Glucuron-, Lactobion-, Benzoe-, Naphthoe-, Succin-, Oxal-, Phenylessig-, Methansulfon-, Ethansulfon-, 2-Hydroxyethansulfon-, Ethan-1,2-disulfon-, Laurylsulfon-, Toluolsulfon-, Benzolsulfon-, Naphthalin-2-sulfon-, Salicyl-, 4-Aminosalicyl-, Sulfanil-, Asparagin-, Glutamin-, Edetin-, Stearin-, Palmitin-, Olein-, Laurin-, Pantothen-, Gerb-, Ascorbin-, Valerian-, Glycol-, Zimt-, Mandel-, 2-Phenoxybenzoe-, 2-Acetoxybenzoe-, Embon-, Nicotin-, Isonicotin-, N-Cyclohexylsulfaminsäure oder anderen sauren organischen Verbindungen, wie beispielsweise 2- oder 3-Phosphoglycerat und Glucose-6-phosphat. Wo die Verbindung eine Säuregruppe enthält, sind geeignete pharmazeutisch vernägliche Salze der Verbindung Additionssalze von pharmazeutisch verträglichen Basen, wie beispielsweise Lithium-, Natrium-, Kalium-, Ammonium-, Magnesium-, Calcium- und Zinksalze, oder Salze, die mit organischen Aminen, wie beispielsweise Methylamin, Dimethylamin, Trimethylamin, Ethylamin, Diethylamin, Triethylamin, N-Methyl-N-ethylamin, Mono-, Bis- oder Tris-(2-hydroxyethyl)amin, 2-Hydroxy-tert-butylamin, Tris(hydroxymethyl)methylamin, N,N-Dimethyl-N-(2-hydroxyethyl)amin, Tri(2-hydroxyethyl)amin, N-Methyl-D-glucamin oder Tributylamin, gebildet werden. Verbindungen der ersten Ausführungsform mit sauren und basischen Gruppen können auch innere Salze bilden. Andere geeignete Salze sind zum Beispiel bei S. M. Berge et al., „Pharmaceutical Salts" („Pharmazeutische Salze") J. Pharm. Sci., 66, 1–19 (1977) beschrieben, welches hier durch Bezugnahme einbezogen ist.
- Der Ausdruck „Prodrug", wie er hier verwendet wird, bezeichnet ein pharmazeutisch verträgliches Derivat einer Verbindung der ersten Ausführungsform, welches nach Verabreichung des Prodrug an ein lebendes Tier oder einen lebenden Menschen in eine Verbindung der ersten Ausführungsform umgewandelt wird und welches Stabilität, Zuführungseigenschaften und/oder therapeutischen Wert hat, die im Vergleich zu der Verbindung der ersten Ausführungsform, aus der es sich ableitet, erhöht sind.
- Die Verbindungen der ersten Ausführungsform können in optisch isomeren Formen existieren. Hier werden alle diese Formen in allen Verhältnissen, einschließlich aller Diastereoisomere und Gemische davon und aller Enantiomere, Gemische von Enantiomeren und racemischer Gemische offenbart. Wo eine Doppelbindung in der Verbindung der Erfindung vorkommt, kann die Doppelbindung in der cis-(Z)- oder trans-(E)Konfiguration vorhanden sein. Es ist selbstverständlich, daß nur Verbindungen der Formel (I) mit Kombinationen von Substituenten oder funktionellen Gruppen, die zu stabilen Verbindungen führen, innerhalb des Schutzbereichs der vorliegenden Erfindung liegen.
- Die Verbindungen der allgemeinen Formel (I) der ersten Ausführungsform können nach Verfahren hergestellt werden, die auf dem Fachgebiet allgemein bekannt sind. Geeignete Verfahren für die Synthese von Verbindungen der Formel (I) und Zwischenverbindungen davon sind zum Beispiel in Houben-Weyl, Methoden der organischen Chemie; J. March, Advanced Organic Chemistry, 3. Auflage (John Wiley & Sons, New York, 1985); D. C. Liotta und M. Volmer, Hrsg. Organic Syntheses Reaction Guide (John Wiley & Sons, Inc., New York, 1991); R C. Larock, Comprehensive Organic Transformations (VCH, New York, 1989); H. O. House, Modem Synthetic Reactions 2. Auflage (W. A. Benjamin, Inc., Menlo Park, 1972); N. S. Simkins, Hrsg. 100 Modern Reagents (The Royal Society of Chemistry, London, 1989); A. H. Haines, Methods for the Oxidation of Organic Compounds (Academic Press, London, 1988) und B. J. Wakefield Organolithium Methods (Academic Press, London, 1988) beschrieben.
- Verbindungen gemäß der vorliegenden Erfindung, die keine solubilisierende Gruppe einschließen, zeigen typischerweise niedrige oder sehr niedrige Wasserlöslichkeit. Inhibitoren von HIV-Proteasen, die bisher beschrieben worden sind, und viele andere pharmazeutische oder veterinäre Wirkstoffe zeigen ebenfalls typischerweise niedrige bis sehr niedrige Wasserlöslichkeit. Diese Eigenschaft neigt dazu zu bewirken, daß die Bioverfügbarkeit derartiger Substanzen relativ niedrig ist. Es besteht somit ein Bedarf für einen HIV-Protease-Inhibitor mit erhöhter Wasserlöslichkeit. Überraschenderweise ist gefunden worden, daß der Einschluß einer solubilisierenden Gruppe, wie sie hier definiert ist, in eine Substanz mit niedriger bis sehr niedriger Wasserlöslichkeit zu einer Erhöhung der Wasserlöslichkeit der Substanz führt. So zeigen Substanzen gemäß der Erfindung, die eine solubilisierende Gruppe einschließen, im Vergleich zu Verbindungen gemäß der Erfindung, die keine solubilisierende Gruppe einschließen, überlegene Bioverfügbarkeit, einschließlich überlegener oraler Bioverfügbarkeit.
- Im allgemeinen schließt eine hier offenbarte Verbindung mindestens eine solubilisierende Gruppe ein, ausgewählt aus
- Typischerweise wird eine solubilisierende Gruppe in das Molekül als letzte Stufe seiner Synthese eingeführt. Zum Beispiel kann eine solubilisierende Gruppe P(O)(OH)2 in eine freie Amino-, Hydroxy-, oder Mercaptogruppe durch Reaktion der Amino-, Hydroxy- oder Mercaptogruppe mit Dimethylchlorphosphat und nachfolgende milde Hydrolyse, um die Methylestergruppen zu entfernen, eingeführt werden. Alternativ kann eine solubilisierende Gruppe P(O)(OH)2 in eine freie Hydroxygruppe durch Reaktion mit phosphoriger Säure und Quecksilber-salzen in Anwesenheit eines tertiären Amins eingeführt werden, wie von Obata und Mukaiyama in J. Org. Chem., 32, 1063 (1967) beschrieben ist. Als weitere Alternative kann eine Amino-, Hydroxyl- oder Mercaptogruppe mit phosphoriger Säure, vorzugsweise bei Vorhandensein eines Kupplungsmittels wie beispielsweise Dicyclohexylcarbodiimid und Pyridin, umgesetzt werden, um ein Molekül zu ergeben, das die solubilisierende Gruppe -OP(O)(OH)H besitzt. Gegebenenfalls kann diese Gruppe zu dem entsprechenden Phosphatderivat, zum Beispiel unter Verwendung von Bis(trimethylsilyl)peroxid, oxidiert werden. Ein weiteres Verfahren für die Einführung einer Gruppe -P(O)(OH)2 ist in der australischen Patentanmeldung Nr. 54311/86 beschrieben und beinhaltet die Reaktion einer Amino-, Hydroxy- oder Mercaptogruppe mit bestimmten Diestern von Amiden von phosphoriger Säure und nachfolgender Oxidation und Hydrolyse der so erhaltenen Zwischenverbindungen.
- Andere Verfahren für die Herstellung von Verbindungen der ersten Ausführungsform, auf die hier Bezug genommen wird, sind in den US-Patentschriften 5116835; 5126326; 5132400; 5145957; 5198426; 5212157; 5215968; 5212667; 5294720 und 5296604; den internationalen Patentanmeldungen Nr. 91/08221; 91/10442; 92/151319 und 92/21696; den europäischen Patentanmeldungen Nr. 0528242; 0519433 und 0432595 und den australischen Patentanmeldungen Nr. 35700/89; 53716/90; 63221/90; 71319/91; 71320/91; 71323/91; 82313/91; 83206/91; 87594/91; 90531/91; 90851/94; 90925/91, 91251/91; 91332/92; 18355/92, 26424/92; 37160/93; 38808/93 und 44930/93 offenbart, die Offenbarungen von jeder von diesen sind hier durch Bezugnahme einbezogen.
