Definitions

• This invention relates to compounds of the general formula (I)
• the compounds of the invention are BRD9 inhibitors. Background of the invention
• Histone acetylation is most usually associated with the activation of gene transcription, as the modification loosens the interaction of the DNA and the histone octomer by changing the electrostatics.
• specific proteins bind to acetylated lysine residues within histones to read the epigenetic code.
• Bromodomains are small (about 110 amino acid) distinct domains within proteins that bind to acetylated lysine resides commonly but not exclusively in the context of histones. There is a family of around 50 proteins known to contain bromodomains, and they have a range of functions within the cell (Filippakopoulos et al., 2012, Cell 149, 214-231).
• BRD9 and BRD7 are two related proteins that have been shown to be part of the chromatin-remodelling BAF (also known as SWI/SNF) complex (Kadoch et al, 2013, Nat. Genet. 45, 592-601; Middeljans et al, 2012, PLoS. One. 7, e33834). Both proteins harbor a bromodomain in the amino -terminal half of the sequence, as well as a domain of unknown function (DUF3512) carboxy-terminally to it.
