PDB Ligand
Compound class: Synthetic organic
Comment: Mivebresib (ABBV-075) is a potent orally available BET inhibitor [1]. BET inhibitors bind to the bromodomains of the bromodomain and extra-terminal motif (BET) proteins BRD2, BRD3, BRD4, and BRDT. This mechanism acts to prevent protein-protein interaction between BET proteins and acetylated histones and transcription factors. The action disrupts chromatin remodeling and inhibits expression of some growth-promoting genes which slows proliferation in susceptible tumours.

Bioactivity Comments
The patent claiming mivebresib (as example 36) provides biochemical and biological data for the compound [2]. It reports a half life in human and rat liver microsomes of >120 minutes (41 minutes in mouse). In the MX-1 human breast cancer xenograft model example 36 causes dose-dependent tumour growth inhibition and inhibits paw swelling in a rat collagen induced arthritis model of inflammation.
