Abstract: New histone deacetylase inhibitors according to the general formula (I) wherein: Q is a bond, CH2, CH—NR3R4, NR5 or oxygen, X is CH or nitrogen, Y is a bond, CH2, oxygen or NR6, Z is CH or nitrogen, R1, R2 are, independently, hydrogen, halogen, C1-C6 alkyl or C1-C6 haloalkyl, R11, R12 are, independently, hydrogen or C1-C6 alkyl, and R3, R4, R5 and R6 are as further defined in the specification.

Abstract: This invention is related to new histone deacetylase inhibitors according to the general formula (I) wherein: Q is a bond, CH2, NR5 or oxygen, X is CH or nitrogen, Y is a bond, CH2, oxygen or NR6, Z is CH or nitrogen, R1, R2 are, independently, hydrogen or C1-C6 alkyl, R3, R4 are, independently, hydrogen, halogen, C1-C6 alkyl, C1-C6 alkoxy, C1-C6 haloalkyl or C1-C6 haloalkoxy, and R5 and R6 are as further defined in the specification, and pharmaceutical acceptable salts thereof.

Abstract: New inhibitors of histone deacetylases having antitumor activity, and the process of preparation thereof are herein described. These compounds belong to the structural formula (I) where R1 is a linear or branched chain containing at least two conjugated double bonds, A is an optionally substituted phenyl or pyridyl ring, Ar is an aryl or heteroaryl group, and R3 is hydrogen or alkoxyalkyl. The application also describes the use of said compounds in the treatment of diseases associated to the deregulation of histone deacetylases activity, such as tumors, as well as the relevant pharmaceutical compositions for administration to patients requiring said treatment.
