LMK235 is a potent and selective histone deacetylase HDAC4 and HDAC5 inhibitor  (IC₅₀ ~11.9 nM and 4.22 nM respectively).  It also has inhibitory activities against HDAC 6, 1, 11, 2, and 8 with IC₅₀ for 55.7, 320, 852, 881, and 1278 nM, respectively. LMK235 exhibits cytotoxity against chemo-resistant cancer cell lines in human ovarian cancer cell lines A2780 and cisplatin resistant A2780CisR (IC₅₀ ~0.49 and 0.32 μM respectively). 

How to Use: 

• In vitro:  LMK235 was used at 1 µM final concentration in vitro and in cellular assays.
• In vivo: n/a
