描述 BRD9 (Bromodomain Containing 9) plays a role in chromatin remodeling and regulation of transcription. It acts as a chromatin reader that recognizes and binds acylated histones. BRD9 is also component of SWI/SNF chromatin remodeling subcomplex GBAF that carries out key enzymatic activities, changing chromatin structure by altering DNA-histone contacts within a nucleosome in an ATP-dependent manner[2]. I-BRD9 is a selective BRD9 inhibitor. According to data obtained by TR-FRET assays, the pIC50s of I-BRD9 against BRD9 and BRD4 were 7.3 and 5.3, respectively, suggesting 100-fold selectivity for BRD9. A nanoBRET assay revealed that the pIC50 of I-BRD9 agianst BRD9 was 6.8. In a BROMOscan profiling against 34 bromodomains, the pKd of I-BRD9 binding BRD9 was 8.7 and good selectivity over other bromodomians was revealed[3]. According data obtained by MTT cytotoxicity assays, the inhibitory IC50s of I-BRD9 against cell proliferation of Rhabdoid tumor cell lines BT12, BT16, Chla266, G401 and KD were 21.2 μM, 11.2 μM, 13.3 μM, 13.4 μM and 8.1 μM, respectively[4]. Kasumi-1 cells were treated by 10 μM I-BRD9 for 6h and results obtained by qPCR assays suggested that I-BRD9 suppressed the genes of CLEC1, DUSP6, FES and SAMSN1[3].
