Bromodomain Inhibitor-13 (Compound 1), an analog of PFI-3, is a bromodomain-containing protein (BCP) inhibitor. It specifically targets the bromodomains of SMARCA2, SMARCA4, and the first and second bromodomains of PB1 [PB1(5) and PB1(2)], with dissociation constants (KD) of 37, 53, 30, and 190 nM, respectively.

DDO-8958 is an orally active and selective BET BD1 inhibitor, exhibiting a KD of 5.6 nM for BRD4 BD1. It shows low nanomolar inhibitory activity across all BET BD1 bromodomains except for BRDT BD1.

GW841819X is an analogue of (+)-JQ1 and a novel inhibitor of BET bromodomains. GW841819X was a single enantiomer but of undefined chirality at the 4-position of the benzodiazepine ring3. GW841819X and JQ1 were recently discovered that bind to the acetyl-lysine binding pocket of BET bromodomains with Kd ranges from 50 to 370 nM [1]. GW841819X bounded to both the individual BD1 and BD2 domains with affinities of 46 and 52.5 nM, respectively. GW841819X-Brd3 interaction was estimated to be around 70 nM4. GW841819X displayed activity in vivo against NUT-midline carcinoma, multiple myeloma, mixed-lineage leukemia, and acute myeloid leukemia1. It also potent induced the ApoA1 reporter gene with an EC50 of 440 nM. It had very little effect on LDL-R luciferase activity at the concentrations at which it induces ApoA1 expression, suggesting that the effect is indeed specific3. GW841819X competed directly with GATA1 site for BD1 binding and also specifically blocked the interaction between Brd3 and acetylated GATA14. Recent findings reported that GW841819X are chose as an interest compound to further develop into potential drugs against diseases including cancer, HIV infection and heart disease2.

Amredobresib is a potent BET inhibitor that impedes the interaction between bromodomains and acetylated lysines on histone H3 and H4, thereby serving as crucial regulators of gene transcription. It proves valuable in the investigation of acute myeloid leukemia (AML) and cancer.
