HDAC6-IN-45

HDAC6-IN-45 (Compound 15) is a selective inhibitor of HDAC6, with an IC50 of 15.2 nM. It exerts neurotrophic effects by upregulating GAP43 and Beta-3 Tubulin markers. Additionally, HDAC6-IN-45 activates the Nrf2 signaling pathway, reduces H2O2-induced ROS production, and inhibits apoptosis in PC12 cells. In zebrafish models of Alzheimer's disease, it demonstrates neuroprotective properties. Moreover, HDAC6-IN-45 exhibits antioxidant activity and has favorable blood-brain barrier (BBB) permeability.
