Name: Mivebresib (ABBV-075)
Brand: Selleck Chemicals
SKU: S8400
Availability: InStock
Rating: 5 (14 reviews)

Cat.No.S8400

Mivebresib (ABBV-075) is a novel BET family bromodomain inhibitor. It binds bromodomains of BRD2/4/T with similar affinities (Ki of 1-2.2 nM) and highly selective for 18 bromodomain proteins tested (Kd > 1 μM; more than 600-fold selectivity vs. BRD4), but exhibits roughly 10-fold weaker potency towards BRD3 (Ki of 12.2 nM) and has moderate activity towards CREBBP (Kd = 87 μM; 54-fold selectivity vs. BRD4). Mivebresib(ABBV-075) efficiently triggers apoptosis in various tumor cell.

Mechanism of Action

Targets/IC₅₀/Ki	BRD2 BRD4 BRD-T
In vitro	Mivebresib (ABBV-075) exhibits robust single agent activity in cell viability assays across cancer cell lines derived from solid tumors, leukemia and lymphomas. It could disrupt cell cycle control leading to G1 arrest followed by senescence, inhibit oncogenesis drivers leading to apoptosis, and potentially target tumor microenvironment to provide additional therapeutic benefit.
In vivo	In flank xenograft mouse models of non-small-cell and small cell lung cancers, pancreatic, breast, prostate, head & neck cancers, multiple myeloma, diffuse large B cell lymphoma and leukemia, Mivebresib (ABBV-075) has comparable or superior efficacies to standard of care agents.
