Abstract: A series of N-substituted amino caproic hydroxamic acid histone deacetylase inhibitors derivatives was designed in good-toexcellent
yields and evaluated for their antiproliferative activity in a panel of human cancer cell lines, showing half maximum effective
concentration varying from 700 nM to > 100 μM. Interestingly, the replacement of a furyl group by a thienyl one impacted
very significantly the cap role on this antiproliferative activity and on histone acetylation induced by these drugs in cell-based but also in
cell-free enzyme assays, suggesting an important role of the electronic density attached to the oxygen or sulfur atoms.
