1,2,4-Triazole amino nucleosides. 1-beta-D-3'-Amino-3'-deoxyribofuranosyl-1,2,4-triazole-3-carboxamide and related nucleosides

Abstract

The synthesis of 1-beta-D-3'-amino-3'-deoxyribofuranosyl-1,2,4-triazole-3-carboxamide--the 3'-amino analogue of ribavirin--and five related nucleoside analogues is described. Each analogue exhibited LD50 concentrations greater than 100 microgram/mL against P-388 mouse lymphoid leukemia cells in tissue culture. Antiviral testing indicated that none of the compounds exhibited significant activity.
