UF010 is a class I HDAC inhibitor with IC50 values of 0.06, 0.1, 0.5, and 1.5 μM for HDAC3, 2, 1, and 8, respectively. It is more than 6-fold selective for these class I HDACs over any additional HDACs. UF010 is reported to inhibit cancer cell proliferation with a mean GI50 value of 2.94 μM when screened against the NCI-60 panel of cancer cell lines and functions by blocking the G1/S phase of the cell cycle.
