HDAC-IN-94
HDAC-IN-94 is a potent, selective HDAC6 inhibitor (IC50 = 4.5 nM). HDAC-IN-94 shows >1000-fold selectivity over HDAC8 and shows minimal activity against other isoforms (HDAC1-3/10). HDAC-IN-94 induces α-tubulin hyperacetylation, apoptosis, and G2/M cell cycle arrest, exhibiting potent anti-tumor efficacy with low cytotoxicity. HDAC-IN-94 can be used for neuroblastoma and glioblastoma research.

HDAC-IN-94 (compound 5o) fits within the catalytic site of hHDAC6 with the hydroxamic acid group, modelled in neutral form, able to chelate the zinc atom, and its polar benzamide hydrogen forming a hydrogen bond with Ser568[1].
HDAC-IN-94 (1-10 μM, 24 h) promotes acetylation of α-tubulin in a dose-dependent manner in SH-SY5Y cells[1].
HDAC-IN-94 (10 nM-30 μM, 24-72 h) shows no cytotoxicity in HEK-293 cells at concentrations up to 30 μM[1].
HDAC-IN-94 (24-72 h) shows antiproliferation activity against U87-MG, T98G, U251-MG and SH-SY5Y cells, with IC50s of 51.31, 42.60, 2.37, and 3.32 μM, respectively[1].
HDAC-IN-94 (3 μM, 24 h) promotes G2/M cell cycle arrest, triggers programmed cell death, and induces a minor autophagy stimulation in SH-SY5Y cells[1].
HDAC-IN-94 (3-30 μM, 24-72 h) demonstrates a clear time- and concentration-dependent pro-apoptotic activity in SH-SY5Y cells[1].
