Abstract:
The present invention provide a heterocyclic compound having a HDAC inhibitory action, and useful for the treatment of autoimmune diseases and/or inflammatory diseases, graft versus host disease, cancers, central nervous diseases including neurodegenerative diseases, Charcot-Marie-Tooth disease and the like, and a medicament comprising the compound. The present invention relates to a compound represented by the formula (I): wherein each symbol is as defined in the specification, or a salt thereof.

Claim (Index 3):
The compound or salt according to  claim 1 , wherein\n R 1  is a C 6-14  aromatic hydrocarbon ring or a 5- to 6-membered monocyclic aromatic heterocycle, each of which is optionally substituted by 1 to 3 substituents selected from (a) a halogen atom, (b) a cyano group, (c) a C 1-6  alkyl group optionally substituted by 1 to 3 substituents selected from\n (i) a mono- or di-C 1-6  alkyl-carbamoyl group, and \n (ii) a halogen atom, \n (d) a C 1-6  alkoxy group optionally substituted by 1 to 3 substituents selected from\n (i) a halogen atom, and \n (ii) a 3- to 14-membered non-aromatic heterocyclic group, \n (e) a C 6-14  aryloxy group, (f) a C 1-6  alkylsulfonyl group, (g) a (C 1-6  alkyl) (C 1-6  alkylsulfonyl)amino group, (h) a mono- or di-C 1-6  alkyl-carbamoyl group, (i) a C 6-14  aryl group, and (j) a 3- to 14-membered non-aromatic heterocyclic group optionally substituted by 1 to 3 oxo groups; R 2  and R 3  are independently (1) a hydrogen atom, (2) a C 1-6  alkyl group optionally substituted by 1 to 3 substituents selected from\n (a) a C 1-6  alkoxy group, \n (b) a mono- or di-C 1-6  alkyl-carbamoyl group, and \n (c) a 3- to 14-membered non-aromatic heterocyclic group optionally substituted by 1 to 3 oxo groups, or \n (3) a mono- or di-C 1-6  alkyl-carbamoyl group; and R 4  and R 5  are independently a hydrogen atom or a C 1-6  alkyl group.
