Selective CBP/p300 bromodomain inhibitor (IC50 values are 125 and 363 nM, respectively). Exhibits >100-fold selectivity for CBP over BRD4. Also exhibits selectivity over a panel of other bromodomains. Reduces LPS-induced IL-1β, IL-6 and IFN-β expression in macrophages in vitro. Also downregulates RGS4 expression in primary cortical neurons in vitro.
Negative Control also available.
Sold for research purposes under agreement from Pfizer Inc.

Cell Cycle & DNA Damage Repair Poster
In normal cells, each stage of the cell cycle is tightly regulated, however in cancer cells many genes and proteins that are involved in the regulation of the cell cycle are mutated or over expressed. Adapted from the 2015 Cancer Product Guide, Edition 3, this poster summarizes the stages of the cell cycle and DNA repair. It also highlights strategies for enhancing replicative stress in cancer cells to force mitotic catastrophe and cell death.
