In order to find novel non-hydroxamate histone deacetylase (HDAC) inhibitors, a series of compounds modeled after suberoylanilide hydroxamic acid (SAHA) were designed and synthesized as (i) substrate (acetyl lysine) analogues (compounds 3-7), (ii) analogues bearing various functional groups expected to chelate zinc ion (compounds 8-15), and (iii) analogues bearing nucleophilic functional groups which could bind covalently to HDACs (compounds 16-18). In this series, semicarbazide 8b and bromoacetamides 18b,c were found to be potent HDAC inhibitors for non-hydroxamates. (C) 2003 Elsevier Ltd. All rights reserved.
