Mecanismo de acción (Mechanism of Action)

Targets/IC50/Ki
BET proteins
(Cell-free assay)
35 nM
In vitro
Molibresib (I-BET-762) is an inhibitor for BET (bromodomain and extra terminal domain) proteins, BRD2, BRD3 and BRD4, which binds to the tandem bromodomains of BET with Kd of 50.5–61.3 nM and displaces a tetra-acetylated H4 peptide prebound to tandem bromodomains of BET with IC50 of 32.5–42.5 nM in FRET analysis. This compound occupies the acetyl-lysine binding pocket of BET proteins and inhibits their binding to acetylated histones, thus disrupting the formation of chromatin complexes essential for expression of inflammatory genes. Treatment with it during the first 2 d of differentiation alters CD4+ T-cell cytokine production, up-regulating expression of several antiinflammatory gene products and down-regulating expression of several proinflammatory cytokines.

Titulaciones de transferencia de energía de resonancia de fluorescencia (FRET). Molibresib (I-BET-762) se titula contra BRD2 (200 nM), BRD3 (100 nM) y BRD4 (50 nM) en 50 mM HEPES pH7.5, 50 mM NaCl, 0.5 mM CHAPS en presencia de péptido de Histona H4 tetra-acetilado (200 nM). Después de equilibrar durante 1 hora, la interacción proteína bromodominio:péptido se detecta usando FRET después de la adición de 2 nM de estreptavidina marcada con criptato de Europio y 10 nM de anticuerpo anti-6His marcado con XL-665 en tampón de ensayo que contiene 0,05% (v/v) BSA y 400 mM KF. Las placas se leen usando un lector de placas Envision (excitación 320 nm, emisión 615 nm y 665 nm).
In vivo
Molibresib (I-BET-762) confers protection against lipopolysaccharide-induced endotoxic shock and bacteria-induced sepsis. A single dose of this compound applied at 1.5 h after LPS injection cures the mice, and twice-daily injections for 2 days protect them against death caused by sepsis. Limited treatment with it exclusively during early priming inhibited the ability of Th1-differentiated 2D2 T cells to induce neuroinflammation in a mouse model of experimental autoimmune encephalomyelitis (EAE).
