    • The present invention relates to a medicine, and more particularly to novel arylamidrazone derivatives having an antagonistic action against S1P 3 receptors and a medicine containing thereof as an active ingredient. The present invention provides an arylamidrazone derivative represented by' the following formula (1) or a pharmaceutically acceptable salt thereof: wherein R 1 represents a C 2 -C 8 alkyl group which maybe substituted, a phenyl group which maybe substituted, an aromatic heterocyclic group which may be substituted, a C 2 -C 8 alkoxy group which may be substituted, or -NR 4 R 5 (wherein R 4 and R 5 , which are identical or different, each represent a hydrogen atom or a lower alkyl group which may be substituted, or R 4 and R 5 may be joined with the adjacent nitrogen atom to form a nitrogen-containing heterocyclic ring which may be substituted); R 2 and R 3 , which are identical or different, each represent a hydrogen atom, a halogen atom, a halo-lower alkyl group, a lower alkyl group, a lower alkynyl group, a lower alkoxy group, a cyano group, a lower alkanoyl group or a lower alkylsulfonyl group; A represents a benzene ring or a heterocyclic ring; D represents a single bond or methylene; m represents an integer from 1 to 3, and n represents an integer from 1 to 5 (with the proviso that the case where R 1 is an ethoxy group, R 2 is a 2,4-dichloro group, R 3 is a hydrogen atom, A is a benzene ring, and D is methylene; and the case where R 1 is an ethoxy group, R 2 is a 2,4-dichloro group, R 3 is a hydrogen atom, a 2-methyl group, a 4-methyl group, a 4-methoxy group or a 4-ethoxy group, A is a benzene ring, and D is a single bond, are excluded).
