Abstract

An object of the present invention is to provide a compound exhibiting an excellent drug efficacy as an anti-adenoviral agent, and an anti-adenoviral agent. The present invention provides an anti-adenoviral agent including a compound represented by General Formula [1] (in the formula, R1 represents a hydrogen atom, a halogen atom, an amino group which may be substituted, a monocyclic nitrogen-containing heterocyclic ring group which may be substituted (provided that a nitrogen atom forming the ring is bonded to a carbon atom to which R1 is bonded), a monocyclic nitrogen- and oxygen-containing heterocyclic ring group which may be substituted (provided that a nitrogen atom forming the ring is bonded to a carbon atom to which R1 is bonded), a C1-6 alkoxy group which may be substituted, a hydroxyl group which may be protected, or the like; R2 represents a hydrogen atom or an amino protecting group; R3 represents a C1-20 alkoxy group which may be substituted, an aryloxy group which may be substituted, an amino group which may be substituted, or the like; R4 represents a C1-20 alkoxy group which may be substituted, an aryloxy group which may be substituted, an amino group which may be substituted, or the like; and X represents an oxygen atom or a sulfur atom) or a salt thereof.
