Mercaptoacetamide: A promising zinc-binding group for the discovery of selective histone deacetylase 6 inhibitors.

ABSTRACT: Histone deacetylase 6 (HDAC6) is a zinc-dependent HDAC that mainly modulates the acetylation status of non-histone substrates, such as α-tubulin and heat shock protein 90 (HSP90). The activity of HDAC6 plays a critical role in cell proliferation, protein trafficking and degradation, cell shape, migration, as well as regulation of immunomodulatory factors. For this reason, HDAC6 influences the progress of cancers, neurodegenerative disorders, and autoimmune responses. In the last few years, the discovery of selective HDAC6 inhibitors (HDAC6is) has become an attractive research area as five HDAC6is are being investigated in phase I/II clinical trials. However, the hydroxamic acid functional group still represents the predominant zinc-binding group (ZBG), that often suffers from poor pharmaco
