Structure-based drug design of novel isoquinoline-5-sulfonamide inhibitors of PKB as potential antitumour agents was investigated. Constrained pyrrolidine analogues that mimicked the bound conformation of linear prototypes were identified and investigated by co-crystal structure determinations with the related protein PKA. Detailed variation in the binding modes between inhibitors with similar overall

An N-heterocyclic carbene catalyzed remote C(sp3)−H acylation of amides was developed, and also combined with a cascade cyclization. Over 120 functionalized δ-amino ketones and isoquinolinones with diverse substituents were synthesized in up to 99 % yield under mild conditions. Preliminary mechanistic investigations shed light on the organocatalytic radical reaction mechanism.
