Functional Differences in Epigenetic ModulatorsSuperiority of Mercaptoacetamide-Based Histone Deacetylase Inhibitors Relative to Hydroxamates in Cortical Neuron Neuroprotection Studies
摘要:
We compare the ability of two structurally different classes of epigenetic modulators, namely, histone deacetylase (HDAC) inhibitors containing either a hydroxamate or a mercaptoacetamide as the zinc binding group, to protect cortical neurons in culture from oxidative stress-induced death. This study reveals that some of the mercaptoacetamide-based HDAC inhibitors are fully protective, whereas the hydroxamates show toxicity at higher concentrations. Our present results appear to be consistent with the possibility that the mercaptoacetamide-based HDAC inhibitors interact with a different subset of the HDAC isozymes [less activity at HDAC1 and 2 correlates with less inhibitor toxicity], or alternatively, are interacting selectively with only the cytoplasmic HDACs that are crucial for protection from oxidative stress.

A series of mercaptoacetamides were designed and synthesized as novel histone deacetylase inhibitors with the aid of modeling. Their ability to inhibit HDAC activity and their effects on cancer cell growth were investigated. Some compounds exhibit better HDAC inhibitory activity than SAHA. (c) 2005 Elsevier Ltd.
