Biological Activity

C 646 is a p300/CREB-binding protein (CBP) inhibitor (Ki = 400 nM). Suppresses histone H3 and H4 acetylation in mouse fibroblast cell lines. Also represses pluripotency markers in mouse embryonic stem cells. Newer p300 probes are also available: iP300w (Cat. No. 7270) and A 485 (Cat. No. 6387).

This compound is a mixture of Z:E isomers (~ 80:20).
