Cat eye syndrome chromosome region candidate 2 (CECR2) bromodomain is a module of CECR2-containing remodeling factor (CERF), which is a chromatin remodeling complex correlating with transcriptional control and adjustment of chromatin architecture. Potent chemical probes would be beneficial to gain insights into the biochemical and pharmacological functions of CECR2 BRD. Herein, we report the discovery of a series of CECR2 BRD inhibitors with 7H-pyrrolo[2,3-d] pyrimidine scaffold based on molecular docking model of TP-248 and CECR2 BRD. The most potent inhibitor of this series, DC-CBi-22 with IC 50 of 8.0 ± 1.4 nM against CECR2 BRD and selectivity over BPTF BRD up to 24.9-fold. The SARs were detailed according to molecular docking. DC-CBi-22 would serve as a useful chemical probe for the study of CECR2.
