C646 was used to study the role of p300 in chronic neuropathic pain in rats with chronic constriction injury.
Biochem/physiol Actions
C646 is a competitive histone acetyltransferase (HAT) p300/CBP inhibitor with a Ki of 400 nM and is selective versus other acetyltransferases.
C646 is a potent, cell permeable and selective inhibitor of p300 and CBP (p300/CBP) histone acetyltransferases. Inhibition of p300/CBP by C646 affects the activity of a variety of transcriptional factors such as NF-?B, p53 and MyoD that are associated with physiology, disease processes, hippocampal synaptic plasticity, spatial memory and contextual fear.
