PF-CBP1 hydrochloride

PF-CBP1 hydrochloride is a highly selective inhibitor of the CREB binding protein bromodomain (CBP BRD). PF-CBP1 inhibits CREBBP and EP300 bromodomains with IC50 of 125 nM and 363 nM respectively. PF-CBP1 hydrochloride reduces LPS-induced inflammatory cytokines expression (IL-1β, IL-6 and IFN-β) in primary macrophages. PF-CBP1 hydrochloride also downregulates RGS4 expression cortical neurons and can be used for the research of neurological disorders, including epilepsy and parkinson's disease, et al.

How to use

In Vitro:

ITC is the label-free technique for determining KD values, PF-CBP1 is against CBP (Kd=0.19 μM) and >105-fold selective over BRD4 (Kd>20 μM) by ITC. PF-CBP1 displays greater than 100-fold selectivity for the bromodomain of CBP over those of BRD4 and a panel of other proteins, it against BRD2-1,BRD3-1, BRD3-2,BRD4-1, BRD4-2, BRDT-1, TAF1-2, and TAF1L-2 with IC50 values of 1.24 μM, 1.38 μM, 4.22 μM, 1.54 μM, 9.75 μM, 2.44 μM, 3.39 μM and 7.29 μM, respectively. PF-CBP1 (3-10 μM; pretreatment 30 mins; 4 hours) moderately reduces LPS-induced IL-6 and IFN-b expression in the J774 cell at 10 μM. And it decreases IL-1b expression evidently at 3 μM. PF-CBP1 (100 nM-1000 nM;24 hours) significantly reduced RGS4 mRNA levels(49% reduction) relative to vehicle in cortical neuron cells.
