title: Potent histone deacetylase inhibitors: N-hydroxybenzamides with antitumor activities.
abstract: The screening tests of N-hydroxybenzamides for their HDAC-inhibitory activities led to the discovery of the promising compounds with a 2-naphthylcarbonyl group and with a 1,4-biphenylcarbonyl group. These compounds were further modified to optimize their physico-chemical profile. As a result, the inhibitor with a 6-amino-2-naphthylcarbonyl was obtained, which showed not only promising growth inhibitions against a panel of tumor cells, but also an improved water solubility. It exhibited the maximal 185% of survival rate (%T/C) in a in vivo experiment with P388 cell-inoculated mice.
