Description:

C646 is a selective and competitive histone acetyltransferase p300 inhibitor with Ki of 400 nM, and is less potent for other acetyltransferases.

In Vitro:

C646 is a linear competitive inhibitor of p300 versus acetyl-CoA with a Ki of 400 nM. C646 shows a noncompetitive pattern of p300 inhibition versus H4-15 peptide substrate. C646 treatment reduces histone H3 and H4 acetylation levels and abrogates TSA-induced acetylation in cells. C646 has a more potent effect on cell growth than Lys-CoA-Tat does[1]. C646 enhances mitotic catastrophe after IR and suppresses phosphorylation of CHK1 after IRin A549 cells[2]. C646 attenuates the increased acetylation of GATA1 and the increased transcriptional activity of GATA1 induced by EDAG[3].
