HDAC8-IN-2 (compound 5o) is a potent HDAC8 inhibitor, with IC50 values of 0.27 μM and 0.32 μM for smHDAC8 (Schistosoma mansoni histone deacetylase 8) and hHDAC8, respectively. It effectively kills schistosome larvae and greatly reduces egg laying in adult worm pairs [1].
HDAC8-IN-3 (compound P19) is a highly potent inhibitor of HDAC8, displaying an IC50 value of 9.3 μM and producing thermal stabilization. Moreover, HDAC8-IN-3 exhibits cytotoxicity and induces apoptosis specifically in leukemic cell lines [1].
