C-646 | HAT inhibitor

C-646 (328968-36-1) is a potent and selective inhibitor of the histone acetyl transferase p300/CBP (Ki=400 nM ). Induces apoptosis in prostate cancer cells. C-646 enhances fear extinction memory and synaptic plasticity in mice. Promotes tau deacetylation reducing levels of pathogenic p-tau. Cell permeable.
