-
, (2021/08/13)
The present disclosure provides an anti-hepatitis B virus agent and a prophylactic or therapeutic agent for hepatitis B virus-related diseases, each comprising a nucleic acid analogue as an active ingredient. The problem can be solved by 2'-deoxy-2'-fluoro-β-2-fluoro-D-adenosine or its prodrug, or a pharmaceutically acceptable salt thereof, or a solvate thereof.

Page/Page column 19, (2008/06/13)
A method for producing 2'-deoxy-2'-fluoro-β-D-arabinonucleoside represented by formula (II): (wherein B represents a base), in particular, 2'-deoxy-2'-fluoro-β-D-arabinopurinenucleoside, which method comprises causing a nucleoside phosphorylase to act on α-1-phosphorylated-2-deoxy-2-fluoroarabinoside represented by formula (I): or a mixture of α- and β-isomers of 1-phosphorylated-2-deoxy-2-fluoroarabinoside represented by formula (V'): and on a base. The compound can be produced at high yield and in a convenient and highly stereoselective manner.

The synthesis of 2-halo-9-(2-deoxy-2-fluoro-β-D-arabinofuranosyl)adenines (4b and 4d) by coupling the 2,6-dihalopurine with 3-acetyl-5-benzoyl-2-deoxy-2-fluoro-D-arabinofuranosyl bromide (2) followed by replacement of the 6-halogen with concomitant removal of the acyl blocking groups is described. 2-Fluoroadenine derivative 4g had to be prepared by the diazotization-fluorination of 2-aminoadenine nucleoside 4e.All three nucleosides provided good increases in life span of mice inoculated with P388 leukemia.The best results were obtained when the compounds were administered q3h*8 on days 1, 5, and 9 after implantation of the leukemia cells.The 2',3'-dideoxynucleoside 5b, prepared by deacetylation of 4f and deoxygenation of the resultant 4h followed by removal of the benzoyl group of 5a, was slightly active against HIV in cell culture.
