Popis: [Image: see text] Necroptosis has been implicated in a variety of disease states, and RIPK3 is one of the kinases identified to play a critical role in this signaling pathway. In an effort to identify RIPK3 kinase inhibitors with a novel profile, mechanistic studies were incorporated at the hit triage stage. Utilization of these assays enabled identification of a Type II DFG-out inhibitor for RIPK3, which was confirmed by protein crystallography. Structure-based drug design on the inhibitors targeting this previously unreported conformation enabled an enhancement in selectivity against key off-target kinases.
