SGC-CBP 30 is a selective inhibitor of CREBBP and EP300 with IC50 value of 21 nM and 38 nM, respectively [1].
EP300 (E1A binding protein p300) is encoded by EP300 gene and plays an important role in regulating cell growth and division, prompting cells mature and assume specialized functions, and preventing tumor cells growth. CREBBP (CREB-binding protein) is encoded by CREBBP gene and involves in the transcriptional coactivation of many different transcription factors [2].

Cell experiment [1]:

Cell lines

HeLa cells and RKO cells

Preparation method

Limited solubility. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reaction Conditions



In HeLa cells, treatment of SAHA-treated cells with 0.1 μM SGC-CBP30 reduces FRAP recovery times back to unstimulated levels. In RKO cells, SGC-CBP30 effectively inhibits the Doxorubicin induced p53 activity in a dose-dependent manner.
