Bicyclic tetrapeptide histone deacetylase inhibitors with methoxymethyl ketone and boronic acid zinc-binding groups
摘要:
Histone deacetylase (HDAC) inhibitors are a class of potential therapeutics for the treatment of cancer. Bicyclic tetrapeptides equipped with methoxymethyl ketone and boronic acid as zinc-binding group were designed and synthesized. The inhibitory activities of these compounds were evaluated against HDAC enzymes. The cell-free and cell-based assay data showed that both potency and selectivity changed with the change in zinc-binding group. Boronic acid-based compound showed poor activity whereas methoxymethyl ketone-based compound displayed impressive activity in both cell-free and cell-based conditions. (C) 2014 Elsevier Inc.

Bicyclic tetrapeptide hydroxamic acids were prepared as histone deacetylase (HDAC) inhibitors, and the evaluated inhibitory activity shows that they are potent against HDAC1 and HDAC4. The in vivo activity depends on alkyl loop length. (c) 2009 Elsevier Ltd. All rights reserved.
