Biochem/physiol Actions

GSK′963 (GSK′963A) is a brain-penetrant, highly potent and selective ATP site-targeting receptor-interacting protein 1 kinase (RIP1; RIPK1) inhibitor (IC50 = 0.8-8 nM with 50 μM ATP; IC50 >10 μM against RIPK2/3/5 and 335 other kinases) that protects against TNFα/zVAD-induced necroptosis (EC50 = 1/4 nM in mouse L929/human U937 cultures) and blocks Y. pestis-induced death of murine fetal liver macrophages (1 μM). GSK′963 prevents lethal hypothermia by acute sterile shock (2 mg/kg i.p. 15 min prior to TNFα/zVAD i.v.) and protects against acute neuronal death upon autologous blood intracerebral hemorrhage induction in mice in vivo (25 mg/kg/3 hr i.p.).

Herpes simplex virus (HSV)-1 and HSV-2 are significant human pathogens causing recurrent disease. During infection, HSV modulates cell death pathways using the large subunit (R1) of ribonucleotide reductase (RR) to suppress apoptosis by binding to and blocking caspase-8. Here, we demonstrate

Recent studies using cultured cells and rodent intracerebral hemorrhage (ICH) models have implicated RIPK1 (receptor interacting protein kinase-1) as a driver of programmed necrosis and secondary injury based on use of chemical inhibitors. However, these inhibitors have off-target effects and

Receptor-interacting protein kinases 1 and 3 (RIPK1/3) have best been described for their role in mediating a regulated form of necrosis, referred to as necroptosis. During this process, RIPK3 phosphorylates mixed lineage kinase domain-like (MLKL) to cause plasma membrane rupture.

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) causes infections associated with extensive tissue damage and necrosis. In vitro, human neutrophils fed CA-MRSA lyse by an unknown mechanism that is inhibited by necrostatin-1, an allosteric inhibitor of receptor-interacting serine/threonine kinase 1 (RIPK-1). RIPK-1

Cell death & disease, 9(3), 346-346 (2018-03-03)
Proteasome inhibitors have achieved clinical success because they trigger intrinsic and extrinsic cell death to eliminate susceptible human cancers. The ubiquitin-proteasome protein degradation system regulates signaling pathways by controlling levels of components such as cellular inhibitor of apoptosis (cIAP)1 and
