bromodomain and extra terminal domain (bet)

I-BRD9 (GSK602) 是一种选择性的 BRD9 细胞抑制剂，pIC50 为 7.3。

BET-IN-28 (Compound 44) 是一种强效的溴结构域和末端外结构域 (BET) 抑制剂，对 BRD4-BD1 的 IC50 值为 4.47 nM。BET-IN-28 能够阻止 BET 蛋白与组蛋白尾部 N-乙酰化赖氨酸残基的相互作用，从而下调特定基因的表达。BET-IN-28 适用于血液系统恶性肿瘤和实体瘤的研究。

EN219 is a synthetic recruiter of the E3 ubiquitin ligase RNF114.1It binds to cysteine 8 (C8) in the intrinsically disordered region of RNF114 (RNF114-C8; IC50= 470 nM) and inhibits RNF114-induced autoubiquitination and p21 ubiquitination in a cell-free assay when used at a concentration of 50 μM. EN219 (1 μM) also interacts with cysteine residues in the tubulin β1 chain (TUBB1), heat shock protein 60 (Hsp60), also known as Hsp family D member 1 (HspD1), and histone H3.1 (HIST1H3A) in 231MFP human breast cancer cells in a proteomic profiling assay. It has been linked to the bromodomain and extra terminal domain (BET) inhibitor ligand (+)-JQ1 for use as a proteolysis-targeting chimera (PROTAC) to degrade bromodomain-containing protein 4 (BRD4) in 231MFP cells. 1.Luo, M., Spradlin, J.N., Boike, L., et al.Chemoproteomics-enabled discovery of covalent RNF114-based degraders that mimic natural product functionCell Chem.

GSK097 is a highly potent and selective inhibitor of the second bromodomain (BD2) found in bromodomain and extra-terminal domain (BET) proteins. It exhibits a remarkable 2000-fold selectivity for BD2 over BD1, as indicated by BRD4 data. Additionally, GSK097 demonstrates solubility of over 1 mg mL in FaSSIF media.

GSK852 是有效的 BD2 选择性 BET 抑制剂，pIC50为 7.9。

(+)-JQ-1 carboxylic acid is a potent bromodomain and extra terminal domain (BET) inhibitor. (+)-JQ-1 carboxylic has potential to be used as a precursor to synthesize PROTACs and other conjugates.
