Biochem/physiol Actions

IACS-9571 is a dimethylamine analogue.
IACS-9571 is a high-affinity, potent TRIM24/BRPF1 bromodomain (BrD) inhibitor (Kd = 1.3/2.1 nM by DiscoveRx) with good selectivity over other BrDs (BRPF2/3 Kd = 12/27 nM, BAZ2B/TAF1 BrD2/BRD4 BrD1,2 Kd = 0.4/1.8/>10 μM by DiscoveRx; ≤63% binding inhibition of 25 other BrDs at 1 μM). IACS-9571 potently blocks H3K23Ac peptide from TRIM24 BrD binding (IC50 = 7.6 nM) and displaces ectopically expressed TRIM24 PHD-BrD from endogenous histone H3 in 2-hr 5 μM SAHA-stimulated HeLa cells (IC50 = 50 nM). When adiministered in mice, IACS-9571 exhibits good pharmacokinetics and oral availability in vivo (F = 29%, 10 mg/kg p.o.).

The bromodomain containing proteins TRIM24 (tripartite motif containing protein 24) and BRPF1 (bromodomain and PHD finger containing protein 1) are involved in the epigenetic regulation of gene expression and have been implicated in human cancer. Overexpression of TRIM24 correlates with

The addressable pocket of a protein is often not functionally relevant in disease. This is true for the multidomain, bromodomain-containing transcriptional regulator TRIM24. TRIM24 has been posited as a dependency in numerous cancers, yet potent and selective ligands for the

Epigenetics & chromatin, 8, 37-37 (2015-09-24)
Proteins that 'read' the histone code are central elements in epigenetic control and bromodomains, which bind acetyl-lysine motifs, are increasingly recognized as potential mediators of disease states. Notably, the first BET bromodomain-based therapies have entered clinical trials and there is
