Mechanism of Action

Targets/IC₅₀/Ki	HDAC5 (Cell-free assay) 4.2 nM HDAC4 (Cell-free assay) 11.9 nM
In vitro	LMK-235 causes HDAC inhibition with IC50 of <1 μM in human cancer cell lines with different sensitivity. In breast cancer cell line MDA-MB-231, tongue cancer cell line Cal27, and esophagus cell line Kyse510 cell line, this compound displays a high cytotoxicity, and markedly enhances the cytotoxicity. In addition, this chemical also shows nanomolar activity against multiple malaria parasite life cycle stages.
Kinase Assay	HDAC IC50 Profiling
Kinase Assay	The in vitro inhibitory activity of compounds against seven human HDAC isoforms (1, 2, 4 C2A, 5 C2A, 6, 8, and 11) are performed with a fluorescent based assay according to the company’s standard operating procedure. The IC50 values are determined using 10 different concentrations with 3-fold serial dilution starting at 10 μM. TSA is used as reference compounds.
In vivo	LMK-235 is a selective inhibitor of HDAC4.
