R1-ICR-5 is a selective PROTAC degrader that targets serine/threonine-protein kinase 1 (RIPK1). R1-ICR-5 mediates the degradation of RIPK1 through VHL, thereby deregulating the TNFR1 and TLR3/4 signaling hubs, enhancing the output of NF-kappaB, MAPK, and IFN signaling, and simultaneously promoting the activation of RIPK3 and the induction of necroptosis. R1-ICR-5 is promising for research of cancers and inflammatory diseases. (Pink: PK68 (HY-128348), Black: linker (HY-W012241), Blue: (S,R,S)-AHPC (HY-125845)[1].
