Upon activation of TNFR1 by the TNF-alpha family cytokines, TRADD and TRAF2 are recruited to the receptor. Ubiquitination by TRAF2 via 'Lys-63'-link chains acts as a critical enhancer of communication with downstream signal transducers in the mitogen-activated protein kinase pathway and the NF-kappa-B pathway, which in turn mediate downstream events including the activation of genes encoding inflammatory molecules. Polyubiquitinated protein binds to IKBKG/NEMO, the regulatory subunit of the IKK complex, a critical event for NF-kappa-B activation. Interaction with other cellular RHIM-containing adapters initiates gene activation and cell death. RIPK1 and RIPK3 association, in particular, forms a necrosis-inducing complex. Publication Abstract from PubMed Receptor-interacting protein kinase 1 (RIPK1) plays an essential role in necroptosis, a form of inflammatory, caspase-independent, programmed cell death. Allosteric inhibitors of RIPK1 have been shown to block necroptotic cell death and thus may offer potential therapeutic opportunities across a range of infectious, autoimmune, and neurodegenerative diseases. We report the structure-informed discovery of a novel series of bridged benzoazepine amides as part of our efforts to develop a CNS-penetrant small-molecule inhibitor of RIPK1 with a low projected oral human dose.
