Abstract
Description
Die vorliegende Erfindung betrifft neue antiviral wirksame Substanzen, deren Herstellungsverfahren sowie Arzneimittel, welche diese neuen Wirksubstanzen enthalten. Bei den Substanzen handelt es sich um acyclische nucleosidanaloge Verbindungen.The present invention relates to new antiviral agents Substances, their manufacturing processes and pharmaceuticals, which contain these new active substances. The substances are acyclic nucleoside analogues Links.
Nucleosid-Analoga, bei denen der Zuckerteil durch einen acyclischen Rest ersetzt ist, besitzen antivirale Wirkung [E. De Clercq et al.; J. Cabohydr. Nucleosides, Nucleotides 5, 187 (1978)].Nucleoside analogues in which the sugar part is replaced by a acyclic residue is replaced, have antiviral activity [E. De Clercq et al .; J. Cabohydr. Nucleosides, Nucleotides 5, 187 (1978)].
9-(2,3-Dihydroxypropyl)adenin (DHPA) hemmt eine Reihe von DNA- und RNA-Viren. [A. Holy, Collect. Czech. Chem. Commun. 40, 187 (1975); 43, 3103 (1978)].9- (2,3-Dihydroxypropyl) adenine (DHPA) inhibits a number of DNA and RNA viruses. [A. Holy, collect. Czech. Chem. Commun. 40: 187 (1975); 43, 3103 (1978)].
Acyclovir® stellt zur Zeit eines der wirksamsten Virustatika gegen Herpes simplex Viren (Typ 1 und Typ 2) dar [Schaeffer, H. J. et al.; Nature 272, 583 (1978); P. Collins et al.; J. Antimicrob. Chemother. 5, 431 (1979)]. Es besitzt jedoch den Nachteil, zu geringer Wasserlöslichkeit. Andere pharmakologische Probleme sind u. a. reversible Knochenmarkstoxizität, Diarrhoe und rasche Resistenzbildung [W. H. Prusoff et al.; Antiviral Research, Suppl. 1,1 (1985)]. Acyclovir® is currently one of the most effective antivirals against herpes simplex viruses (type 1 and type 2) [Schaeffer, H. J. et al .; Nature 272, 583 (1978); P. Collins et al .; J. Antimicrob. Chemother. 5, 431 (1979)]. However, it has the disadvantage of being too small Solubility in water. Other pharmacological problems are u. a. reversible bone marrow toxicity, diarrhea and rapid development of resistance [W. H. Prusoff et al .; Antiviral Research, Suppl. 1.1 (1985)].
Um die Selektivität, Löslichkeit, orale Absorption und Wirkung von Acyclovir zu erhöhen, wurden eine Reihe von Derivaten synthetisiert und im Hinblick auf ihre antivirale Wirksamkeit getestet [K. K. Ogilvie et al.; Antimicrob. Agents Chemother. 22, 55 (1982); Schaeffer, H. J. et al.; Proc. Natl. Acad. Sci. USA 81, 3209 (1984)].To selectivity, solubility, oral absorption and Acyclovir has been shown to increase effect of a number of Derivatives synthesized and in terms of their antiviral Effectiveness tested [K. K. Ogilvie et al .; Antimicrobial. Agents chemother. 22, 55 (1982); Schaeffer, H. J. et al .; Proc. Natl. Acad. Sci. USA 81: 3209 (1984)].

Überraschenderweise wurde nun gefunden, daß die neuen Verbindungen in Zellkulturen schon in geringer Konzentration hervorragend antiviral wirken und auch in höheren Konzentrationen nicht oder nur sehr schwach zelltoxisch sind. Dadurch besitzen die neuen Verbindungen einen hohen therapeutischen Wert. Die Verbindungen sind gut löslich, was für eine Anwendung in höherer Konzentration, z. B. als Injektions- und Infusionslösung zur Behandlung schwerer Viruserkrankungen sehr vorteilhaft ist.Surprisingly, it has now been found that the new Compounds in cell cultures even in low concentrations have an excellent antiviral effect and also in higher ones Concentrations not or only very weakly toxic to cells are. This gives the new connections high therapeutic value. The connections are readily soluble, what an application in higher concentration, e.g. B. as a solution for injection and infusion Treatment of severe viral diseases very beneficial is.
Das nachfolgende Ausführungsbeispiel erläutert die Erfindung.The following embodiment explains the invention.

[J. Org. Chem. 48, 2953 (1983)], 9,1 g (0,1 Mol) Paraformaldehyd
und 190 ml absol. Dichlormethan wird solange
HCl-Gas eingeleitet, bis die Lösung gesättigt
ist. Die trübe, farblose Lösung wird über Calciumchlorid
getrocknet, filtriert und im Vakuum eingeengt.
Das bei dieser Reaktion gebildete 1-Chlor-3-acetoxy-2-
chlormethoxypropan ist für weitere Umsetzungen ohne
weitere Reinigung einsetzbar.

Chem. 48, 2953 (1983)], 9.1 g (0.1 mol) of paraformaldehyde and 190 ml of absolute. HCl gas is passed in until the solution is saturated. The cloudy, colorless solution is dried over calcium chloride, filtered and concentrated in vacuo. The 1-chloro-3-acetoxy-2-chloromethoxypropane formed in this reaction can be used for further reactions without further purification.
Yield: 58.2 g (96.5%) colorless liquid.
7,3 g (20 mmol) 2,6,9-Tris-trimethylsilylguanin löst

Rühren bei Raumtemperatur eine Lösung aus 5 g (25 mmol)
1-Chlor-3-acetoxy-2-chlormethoxypropan in 20 ml absol.
Acetonitril, das 0,5 mmol SnCl₄ enthält, zu. Nun wird
die Mischung 3¼ Std. auf 80 Grad erwärmt. Anschließend
zieht man die flüchtigen Bestandteile am Rotationsverdampfer
ab. Der braune, halbfeste Rückstand wird mit
Wasser versetzt, um nicht umgesetztes Silylderivat zu
zerstören. Nun gibt man Dichlormethan zu und rührt ungefähr
½ Std. Dann wird der Ansatz über Kieselgur abgesaugt.
Man trennt die Phasen, wäscht die organische
Phase hintereinander mit gesättigter NaHCO₃-Lösung und
Wasser aus. Die organ. Phase wird dann über Na₂SO₄ getrocknet.

Festkörpers vom Schmelzpunkt: 148-152°. Aus ¹H-NMR-Spektrum
und Elementaranalyse geht hervor, daß es sich um
die gewünschte Verbindung handelt.
