Docking Study of HDAC Implication for Benzamide Inhibitors Binding Mode

Abstract

The paper proposed a possible binding mode of MS-275, a benzamide historic deacetylase(HDAC) inhibitor, to HDAC by intensive docking study. This binding mode is different from those observed in the crystal structure of complexes formed by a histone deacetylase-like protein (HDLP) with trichostatin A(TSA) or suberoylanilide hydroxamic acid (SARA). The docking result implicates that the main target of MS-275 is the narrowest part of HDAC active pocket. It seems to be able to explain the low toxicity of MS-275 and provides new insights on the design of novel HDAC inhibitors.
