Details


Biological Activity:

C646 is a potent, selective and cell-permeable p300/CBP histone acetyltransferase (HAT) inhibitor with an IC50 ~400 nM. It competes with acetyl-CoA for the p300 Lys-CoA binding pocket selectively. It blocks the growth of human melanoma, leukemia, lung, and prostate cancer cells in vitro. C646 has also been used to study the role of p300-mediated gene regulation in neuroscience. The histone acetyltransferase (HAT) p300/CBP is a transcriptional coactivator implicated in many gene regulatory pathways and protein acetylation events. C646 is a useful chemical probe to study p300/CBP HAT functions. 

 

How to Use:

In vitro:  C646 was used at 10 µM final concentration in various in vitro assays.

In vivo: C646 was dosed to mice by Alzet pumps at 0.9 mg/kg per day for 14 days.
