Compounds represented by formula (I) wherein N1 represents an atom to which a donor hydrogen atom in a hydrogen bond donor group is bonded or a hydrogen bond acceptor atom in a hydrogen bond acceptor group; N3 represents a hydrogen bond acceptor atom in a hydrogen bond acceptor group; and N2, N4 and N5 represent each an arbitrary carbon atom constituting a hydrophobic group; having an atom corresponding to N3 and atoms corresponding to at least two atoms selected from N1, N2, N4 and N5 among the five atoms constituting a pharmacophore specified by the interatomic distances among N1, N2, N3, N4 and N5; and, in the optimized stereochemical structure thereof, the interatomic distances between the atom corresponding to N3 and atoms corresponding to at least two atoms selected from N1, N2, N4 and N5 fall within the scope of the pharmacophore interatomic distance, or salts thereof. Because of having an effect of inhibiting the activity of a transcription factor AP-1, these compounds are useful as preventives/remedies for diseases in which the excessive expression of AP-1 participates and as AP-1 inhibitors.
