Design and synthesis of novel isoxazole-based HDAC inhibitors

A series of isoxazole-based histone deacetylase (HDAC) inhibitors structurally related to SAHA were designed and synthesized. The isoxazole moiety was inserted in the vicinity of the Zn2+-binding group in order to check its participation in the coordinating process. New isoxazole-based histone deacetylase inhibitors structurally related to SAHA were designed and synthesized to check the participation of the isoxazole moiety in the Zn 2+coordination.
