Histone deacetylases (HDACs) catalyze the hydrolytic removal of acetyl groups from histone lysine residues, which commonly results in chromatin condensation and transcriptional repression. LMK 235 is an HDAC inhibitor that selectively targets HDACs 4 and 5 (IC₅₀s = 12 and 4 nM, respectively) over other HDACs (IC₅₀s = 56, 320, 850, 880, and 1,280 for HDACs 6, 1, 11, 2, and 8, respectively). It displays enhanced cytotoxic effects against human cancer cell lines, compared to SAHA or trichostatin A . LMK 235 and derivatives inhibit the growth of the malarial parasite P. falciparum at multiple life cycle stages at nanomolar concentrations.

LMK 235 is a histone deacetylase (HDAC)4 and HDAC5 inhibitor and has shown to have enhanced cytotoxic effects against the human cancer cell lines A2780, Cal27, Kyse510, and MDA-MB231.

LMK-235 induces the differentiation of odontoblasts in dental pulp cells. It plays an important role in the regeneration of dental tissue.

HDAC5: 4.22 nM (IC₅₀); HDAC4: 11.9 nM (IC₅₀); HDAC6: 55.7 nM (IC₅₀); HDAC1: 320 nM (IC₅₀); HDAC11: 852 nM (IC₅₀); HDAC2: 881 nM (IC₅₀); HDAC8: 1278 nM (IC₅₀)
