(EN) The subject invention discloses compounds, compositions and methods for treatment and prevention of toxicity due to chemotherapeutic agents and antiviral agents. Disclosed are acylated derivatives of non-methylated pyrimidine nucleosides. These compounds are capable of attenuating damage to the hematopoietic system in animals receiving antiviral or antineoplastic chemotherapy.(FR) La présente invention se rapporte à des composés, des compositions et des procédés de traitement et de prévention de la toxicité due à des agents chimiothérapeutiques et antiviraux. L'invention se rapporte également à des dérivés acylés de nucléosides de pyrimidine non méthylés. Ces composés peuvent atténuer les lésions du système hématopoïétique chez des animaux subissant une chimiothérapie antivirale ou antinéoplasique.

An antitumor composition was prepared by admixing a 5-fluorohexahydropyrimidine of the formula (I)
wherein R' is a lower alkyl group and R2 is a hydrogen atom or a lower alkyl group, and a pyrimidine nucleic acid base and/or the riboside thereof. Thus, the antitumor activity of the 5-fluorohexahydropyrimidine of the formula (I) is remarkably increased by the joint use of a pyrimidine nucleic acid base and/or the riboside thereof, which has little antitumor activity.
