o)benzenesulfonamide inhibitors that display excellent potency and selectivity against a broad spectrum of protein kinases. Crystal structures of prototypical members bound to the ATP-binding site of TNNI3K reveal two anchoring hydrogen bond contacts: (1) from the hinge region amide N–H to the pyrimidine nitrogen and (2) from the sulfonamide N–H to the gatekeeper threonine. Evaluation of various para-substituted

]imidazole‐6‐sulfonamides as Bromodomain and Extra‐Terminal Domain (BET) Inhibitors with Selectivity for the First Bromodomain
Bioisosteric replacement of the azobenzene moiety of selective BET inhibitors with a benzimidazole ring afforded a set of benzimidazole-6-sulfonamides. Evaluation of the binding activity against diverse BRD families endorses the benzimidazole as a useful scaffold to obtain compounds with improved selectivity towards the firstbromodomains of BET family proteins.
