Abstract

5-Haloalkyl-pyridine nucleosides (I) are used in combatting malignant and viral diseases: In (I), R is 1-6C haloalkyl; X is H or OH; and Y is -CO-R1, -CO-CH2-O-CO-R1, 1-adamantylcarbonyl, -CO-(CH2)n-p-C6H4-R2, -CO-(CH2)n-CN, -CO-C(Hal)3 or a group -CO-(CH2)n-CO-A in which R1 is 1-6C alkyl, R2 is NH2 or COOH, n is 1,2,3 or 4, Hal is F or Cl, and A is a residue corresponding to formula (I) minus the resd residue Y; and the 3'-OH group may be esterified with Y instead of the 5'-OH group. (I) are active against virus strains resistant to known 5-haloalkyl-deoxyuridine antivirals (e.g. 5-trifluoromethyl deoxyuridine, 5-bromovinyldeoxyuridine), and have more favourable pharmacokinetic properties than the known cytostatic agent trifluorothymidine.

Description

Verwenduno von 5-Haloalkyl-pyrimidinnukleosi-Use of 5-haloalkyl-pyrimidine nucleosi-

den als Virostatika und Cytostatika 5-Haloalkyldesoxyuridine, z.B. 5-Trifluormethyl desoxyuridin und 5-Bromvinyldesoxyuridin stellen virostatische insbesondere bei Herpes-Viren wirksame Substanzen dar. Deren Anwendung ist jedoch mit Nachteilen behaftet, denn die Herpes-Viren entwickeln häufig Resistenzen gegenüber diesen Substanzen. Auch die an sich bekannte cytostatische Wirksamkeit von Trifluorthymidin ist mit Nachteilen verbunden, die sich aus dem ungünstigen pharmokokinetischen Verhalten dieser Substanz ableiten.as antivirals and cytostatics 5-haloalkyldeoxyuridines, e.g., 5-trifluoromethyl deoxyuridine and 5-bromovinyl deoxyuridine are virostatic in particular in the case of herpes viruses are effective substances. However, their application is fraught with disadvantages, because the herpes viruses often develop resistance to it these substances. Also the known cytostatic effectiveness of trifluorothymidine is associated with disadvantages arising from the unfavorable pharmocokinetic behavior derive from this substance.

Oberraschenderweise wurde nun gefunden, daß die erfindungsgemäßen 5-Haloalkyl-pyrimidinnukleoside gegenüber den bekannten Substanzen wesentliche Vorteile aufweisen, da sie einerseits gegenüber resistenten Herpes-Viren wirksam sind und andererseits ein günstigeres pharmakokinetisches Verhalten aufweisen.Surprisingly, it has now been found that the invention 5-Haloalkyl-pyrimidine nucleosides have significant advantages over the known substances have, since they are effective on the one hand against resistant herpes viruses and on the other hand have a more favorable pharmacokinetic behavior.
