Claim:
A compound having the following formula (I) or a salt thereof: (wherein A is O, S or NR 7 in which R 7 is hydrogen or C 1-8 alkyl; B 1 is CW or N in which W is hydrogen or a bond; B 2 is O, S or NR 8 in which R 8 is hydrogen or C 1-8 alkyl; each of X 1 and X 2 is O, S, NH, NHC(═O), C(═O), C(═N—OR 9 ), CH(OR 10 ), C═C, C≡C or a bond in which each of R 9 and R 10 is hydrogen or C 1-8 alkyl; Y is a C 1-8 alkylene chain, which can be substituted with C 1-8 alkyl or C 1-8 alkyl substituted with 1–3 halogens; Z is NH, O or S R 1 is aryl, which can be substituted with a group or atom selected from the group consisting of C 1-8 alkyl, C 1-8 alkoxy, C 1-8 alkyl substituted with 1–3 halogens, hydroxyl, nitro, amino, phenyl, pyridyl and halogen, or a heterocyclic group having five to eight membered ring comprising one to three hetero atoms selected from the group consisting of nitrogen, oxygen and sulfur and the other atoms consisting of carbon (benzene ring can be condensed with the heterocyclic ring); R 2 is C 2-8 alkyl, C 1-8 alkyl substituted with 1–3 halogens, C 3-7 cycloalkyl, C 2-8 alkenyl, C 2-8 alkynyl, alkyl (comprising C 1-4 alkyl moiety) substituted with aryl, which can be substituted with a group or atom selected from the group consisting of C 1-8 alkyl, C 1-8 alkoxy, C 1-8 alkyl substituted with 1–3 halogens, hydroxyl, nitro, amino, phenyl, pyridyl and halogen, or alkyl (comprising C 1-4 alkyl moiety) substituted with a heterocyclic group having five to eight membered ring (comprising one to three hetero atoms selected from the group consisting of nitrogen, oxygen and sulfur and the other atoms consisting of carbon); R 3 is halogen, trifluoromethyl, C 1-8 alkyl, C 2-8 alkenyl or C 2-8 alkynyl; each of R 4 and R 5 is hydrogen, C 1-8 alkyl or C 1-8 alkyl substituted with 1–3 halogens; and R 6 is hydrogen, C 1-8 alkyl substituted with amino, C 1-8 alkyl or alkali metal; provided that each of Z and R 3 is attached to the benzene ring, and X 2 is not attached to the benzene ring.
