Abstract:
The present invention provides 2-furancarboxylic acid hydrazide compounds represented by General Formula (I) below, and prodrugs, physiologically acceptable salts, hydrates, solvates thereof: wherein A is a group represented by Formula (a) or the like: (wherein either R4 or R5 represents cyano, nitro or the like, and the other represents a hydrogen atom or the like); either R1 or R2 represents a group: -D-(X)m-R6 or the like, and the other represents a group: -E-(Y)n-R7, hydrogen atom, aryl or the like; R3 is a hydrogen atom or the like; D and E independently represent aryl; X and Y independently represent O or the like; R6 and R7 independently represent alkyl, aryl, arylalkyl or the like; and m and n are independently 0 or 1, provided that the aryl is optionally substituted.
