KT-531 (KT531) is a potent, selective HDAC6 inhibitor with IC50 of 8.5 nM, displays 39-fold selectivity over other HDAC isoforms.
KT-531 demonstrated biological potency in multiple hematological cancer cell models (acute myeloid leukemia (AML), PTCL, and T-cell acute lymphoblastic leukemia (T-ALL)) and limited cytotoxicity in nonmalignant cell types as well as no observable toxicity in vivo (CD-1 mice).
KT-531 exhibited strong potency (IC50=0.42 μM) in the T-ALL/T-PLL-like cell line SUP-T11, demonstrated higher cytotoxicity than Nexturastat in MV4-11 cancer cells (IC50=0.42 uM versus 1.68 uM).
KT-531 showed high synergy with chemotherapeutic agents idasanutlin, bendamustine, and venetoclax in T-PLL patient samples.
KT-531 is the first HDAC6 inhibitor to show efficacy in T-PLL patient samples.
