Contraceptive activity as well as anti-viral protection can be provided by contraceptive compositions containing a pyrimidine-based nucleoside or nucleotide exhibiting spermicidal or sperm-immobilizing activity. In one example, the active ingredient contains a thymine ring (e.g. AZT) that has 5-halo, 6-alkoxy substitution. Additional improvements in anti-HIV activity for certain AZT derivatives are seen by providing the pentose ring of AZT with aryl phosphate substitution.

Dans l'un des exemples, le principe actif contient un cycle thymine, c'est le cas notamment de l'AZT, présentant une substitution 5-halo, 6-alcoxy. L'invention concerne également d'autres améliorations de l'activité anti-VIH de certains dérivés de l'AZT, améliorations que l'on obtient grâce à une substitution aryl-phosphate sur le cycle pentose de l'AZT.
