WMJ-J-09 is an HDAC inhibitor with IC50 values of 7.5 nM (HDAC1), 21.3 nM (HDAC2), 18.4 nM (HDAC3), 90.9 nM (HDAC8), 3.9 nM (HDAC6) and 8715.7 nM (HDAC4). WMJ-J-09 blocks the cell cycle and induces apoptosis in cancer cells. WMJ-J-09 induces cancer cell death through the LKB1-AMPK-p38MAPK-p63-survivin signaling cascade.WMJ-J-09 inhibits HDAC enzyme activity, leading to acetylation of key proteins and thereby regulating cancer cell death. WMJ-J-09 can be used in HCT116 cells and FaDu cells research[1][2].
