HDAC6-IN-82
HDAC6-IN-82 is a selective HDAC6 inhibitor with an IC50 of 4.9 nM against HDAC6. HDAC6-IN-82 inhibits HDAC1 (112 nM), HDAC2 (737 nM), HDAC3 (623 nM), HDAC8 (1140 nM), HDAC10 (91.4 nM) and HDAC11 (219 nM). HDAC6-IN-82 reduces cancer cell viability, induces cell cycle arrest, triggers apoptosis, and increases the acetylation levels of H3K9 and α-tubulin. HDAC6-IN-82 can be used in cancer-related research such as leukemia.

HDAC6-IN-82 (Compound 14b) (48 h) reduces cell viability in a panel of human solid tumor and hematologic cancer cell lines, with the strongest potency against HL60 and U937 leukemia cells (CC50 = 1.2 μM and 1.3 μM)[1].
HDAC6-IN-82 (0.125-0.25 μM; 24-48 h) induces apoptosis in U937 acute myeloid leukemia cells in a time- and dose-dependent manner[1].
HDAC6-IN-82 (0.0675-0.25 μM; 48 h) inhibits nuclear and cytoplasmic HDAC activity in U937 acute myeloid leukemia cells[1].
Treatment of U937 acute myeloid leukemia cells with HDAC6-IN-82 (0.0675-0.25 μM; 48 h) modulates the mRNA expression of cell cycle and apoptosis regulators, upregulating p21, Bak and Bax while downregulating cyclin D1 and Bcl-2[1].
HDAC6-IN-82 (0.0675-0.25 μM; 48 h) regulates miRNA expression in U937 acute myeloid leukemia cells after 48 h of treatment, downregulating anti-apoptotic miRNAs involved in apoptosis regulation and upregulating pro-apoptotic miRNAs[1].
