Claim:
A compound represented by the following formula (I) or a salt thereof: wherein: m represents 1; E represents the following formula (II): wherein R 35 represents the formula —X—Y′; and one of R 31 , R 32 , R 33 and R 34 represents the formula R 1 -T-, and each of the other three independently represents a hydrogen atom or a group selected from the following substituent group γ-1; R 1 represents a C 6-10 aryl group or a C 6-10 aryl group substituted with one to five groups selected from the following substituent group α-1, wherein, when the number of the substituents is two or more, each of the substituents may be the same or different; T represents a single bond or —O—; G represents an oxygen atom; R 2 represents a C 6-10 aryl group or a C 6-10 aryl group substituted with one to five groups selected from the following substituent group β-1, wherein, when the number of the substituents is two or more, each of the substituents may be the same or different; X represents —CH═CH—, or —CH 2 CH 2 —; Y′ represents a carboxy group; and M represents a single bond, or the formula —Z 2 —O— wherein, the bond at the left-hand end binds to G, and the bond at the right-hand end binds to R 2 in each of the formulas; and Z 2 represents a C 1-9 straight chain alkylene group; provided that: when R 33 is the formula R 1 -T-; each of R 31 , R 32 and R 34 is a hydrogen atom; R 1 is a C 6-10 aryl group or a C 6-10 aryl group substituted with a group or groups selected from a halogen atom, a nitro group, a C 1-6 alkyl group, a halogenated C 1-6 alkyl group, a C 1-6 alkoxy group, a halogenated C 1-6 alkoxy group, a C 1-6 alkylsulfanyl group, an amino group and a C 1-6 alkylenedioxy group; R 2 is a C 6-10 aryl group or a C 6-10 aryl group substituted with a group or groups selected from a halogen atom, a nitro group, a C 1-6 alkroup, a halogenated C 1-6 alkyl group, a C 1-6 alkoxy group, a halogenated C 1-6 alkoxy group, a phenyl group and a carboxy group; and M is a single bond; then T represents is —O—; [substituent group α-1] a halogen atom, a cyano group, a nitro group, a C 1-6 alkyl group, a halogenated C 1-6 alkyl group, a C 1-6 alkoxy group, a halogenated C 1-6 alkoxy group, a C 1-6 alkylsulfanyl group, an amino group and a C 1-6 alkylenedioxy group; [substituent group β-1] a halogen atom, a nitro group, a C 1-6 alkyl group, a halogenated C 1-6 alkyl group, a C 1-6 alkoxy group, a halogenated C 1-6 alkoxy group, a C 1-6 alkylsulfanyl group, a phenyl group and a carboxy group; [substituent group γ-1] a halogen atom, a C 1-6 alkyl group and a C 1-6 alkoxy group.
