HDAC3-IN-T326 is a potent and selective HDAC3 inhibitor that acts by increasing NF-κB acetylation and activating HIV gene expression in latent HIV-infected cells.
HDAC8-IN-3 (compound P19) is a highly potent inhibitor of HDAC8, displaying an IC50 value of 9.3 μM and producing thermal stabilization. Moreover, HDAC8-IN-3 exhibits cytotoxicity and induces apoptosis specifically in leukemic cell lines [1].
HDAC3 inhibitor is an allosteric inhibitor of histone deacetylase 3 (HDAC3; Ki = 0.16 nM). It is selective for HDAC3 over HDAC1 and HDAC2 (IC50s = 0.95, 11.81, and 95.45 nM, respectively, using recombinant HDACs). In addition, it is selective for acute myeloid, monocytic, and lymphoblastic leukemia cell lines (EC50s = 36.37, 76.64, and 151.7 nM, respectively) over chronic myeloid, acute promyelocytic, and acute lymphoblastic cells (EC50s = 2,160, >10,000, and >10,000 nM, respectively).
HDAC6-IN-3 (Compound 14) is a potent anti-prostate cancer agent that acts as an orally active inhibitor of HDAC6. It has IC50 values ranging from 0.02-1.54 μM for HDAC1, HDAC2, HDAC3, HDAC6, HDAC8, and HDAC10. Additionally, HDAC6-IN-3 also demonstrates effective inhibition of MAO-A (IC50 = 0.79 μM) and LSD1 [1].
