Anti-human immunodeficiency and anti-hepatitis B virus activities of β-l-2′,3′-dideoxy purine nucleosides
摘要:
beta-L-2',3'-Dideoxyadenosine, beta-L-2',3'-didehydro-2',3'-dideoxyadenosine and related compounds were synthesized in a stereoselective manner. These compounds were tested in vitro against HBV in 2.2.15 cell line and against HIV-1 in PBM and CEM cells. It was found that beta-L-2',3'-didehydro-2',3'-dideoxyadenosine (7) exhibited significant anti-HIV (EC(50) 0.38 mu M in PBM cells) and anti-HBV activity (EC(50) 1.2 mu M).

A method of making didanosine (ddI) including the steps of: (a) obtaining an enzyme expressing ddA deaminase activity; (b) immobilizing the enzyme onto an insoluble support; (c) contacting the enzyme with a dideoxyadenosine (ddA) solution of at least about 4% weight volume ddA in water for a time and under conditions to produce a ddI solution; and (d) isolating the ddI from the ddI solution. Optionally, the ddI mother liquor is reused in subsequent runs to improve yield.

(EN) The present invention relates to the discovery that certain dideoxynucleoside analogs which contain a dideoxy ribofuranosyl moiety having an L-configuration (as opposed to the naturally occurring D-configuration) exhibit unexpected activity against Hepatitis B virus (HBV). In particular, the compounds according to the present invention show potent inhibition of the replication of the virus in combination with very low toxicity to the host cells (i.e., animal or human tissue). Compounds according to the present invention exhibit primary utility as agents for inhibiting the growth or replication of HBV, HIV and other retroviruses, most preferably HBV. The compound 1-(2,3-dideoxy-beta-L-ribofuranosyl)-5-fluorocytosine is shown to be a potent anti-HIV agent with low toxicity to host cells.(FR) L'invention concerne la découverte que certains analogues de didésoxy nucléosides contenant une fraction didésoxy ribofuranosyle présentant une configuration L (à la différence de la configuration D naturelle) présentent une activité inattendue contre le virus de l'hépatite B. Les composés de l'invention présentent notamment une puissante inhibition de la réplication du virus en combinaison avec une très faible toxicité vis-à-vis des cellules hôtes (c'est-à-dire, des tissus animaux ou humains). Les composés de l'invention présentent une utilité principale comme agents destinés à inhiber la croissance et la réplication du virus de l'hépatite B, du VIH et d'autres rétrovirus, de préférence le virus de l'hépatite B. On a démontré que le composé 1-(2,3-didésoxy-béta-L-ribofuranosyle)-5-fluorocytosine constitue un agent puissant anti-VIH présentant une faible toxicité à l'égard de cellules hôtes.
