TYA-018 (TYA018) is a potent, isoform-selective inhibitor of HDAC6 with IC50 of 10 nM, inhibits tubulin acetylation (Ac-Tubulin) with EC50 of 120 nM in cell-based assay in induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs).

YAK540 is a potent, highly selective class IIa HDAC inhibitor with IC50 of 114 nM (HDAC4), displays excellent selectivity against HDAC2 (265-fold), HDAC6 (100-fold), and HDAC8 (82-fold).

Yanostat (KH16) is a novel potent HDAC inhibitor with low nanomolar in vitro activity against class I HDACs (HDAC1/2/3 IC50=13/34/6 nM).

YSL-109 (YSL109) is a potent, highly selective small molecule inhibitor of HDAC6 with IC50 of 0.537 nM, >4000-fold selectivity over HDAC1 and HDAC8.

YSR734 is a first-in-class covalent HDACs inhibitor with IC50 of 0.109 uM, 0.154 uM and 0.143 uM for HDAC1, HDAC2, and HDAC3, sparing other deacetylases (HDAC4-HDAC10, IC50>10 uM).
