Patent ID: 8530490

Claim:
A uracil compound of formula (I) or a salt thereof: wherein: n is an integer from 1 to 3; X is a bond, an oxygen atom, a sulfur atom, an alkenylene group having comprising 2 to 6 carbon atoms, an optionally substituted divalent aromatic hydrocarbon group, or an optionally substituted divalent saturated or unsaturated heterocyclic group; Y is a bond or a linear or branched alkylene group comprising 1 to 8 carbon atoms, which optionally has a cycloalkylidene structure on one carbon atom; and Z is SO 2 NR 1 R 2 or —NR 3 SO 2 —R 4 , wherein: R 1 and R 2 are each independently a hydrogen atom, an alkyl group comprising 1 to 6 carbon atoms, or an optionally substituted aralkyl group, wherein when an aromatic hydrocarbon group constituting the aralkyl group is a phenyl group, the phenyl group may form a condensed bicyclic hydrocarbon group, together with the substituent, or R 1 and R 2 are taken together with the adjacent nitrogen atom to form an optionally substituted saturated heterocyclic group; R 3 is a hydrogen atom or an alkyl group comprising 1 to 6 carbon atoms; and R 4 is an optionally substituted aromatic hydrocarbon group or an optionally substituted unsaturated heterocyclic group excluding a uracil compound of formula (I), wherein n is 3, X is a bond, Y is a bond, Z is —NR 3 SO 2 R 4 , R 3 is a hydrogen atom, and R 4 is a 5-(dimethylamino)-1-naphthyl group; and n is 3, X is a bond, Y is a bond, Z is —NR 3 SO 2 R 4 , R 3 is a hydrogen atom, and R 4 is a 4-methylphenyl group.
