UF-010 is a Class I HDAC inhibitor (IC50 values are 0.06, 0.1, 0.5 and 1.5 M for HDACs 3, 2, 1 and 8, respectively). UF010 inhibits cancer cell proliferation via class I HDAC inhibition. This causes global changes in protein acetylation and gene expression, resulting in activation of tumor suppressor pathways and concurrent inhibition of several oncogenic pathways. The isotype selectivity coupled with interesting biological activities in suppressing tumor cell proliferation support further preclinical development of the UF010 class of compounds for potential therapeutic applications.
