Citronellol ((±)-β-Citronellol) is used in insect repellents and perfumes and as a mite attractant.

Necrostatin-5 (Nec-5) is a selective RIP1 kinase inhibitor and cell necrosis inhibitor that prevents the death of Fadd-deficient Jurkat cells treated with TNF-α, with an EC50 of 240 nM.

GSK2593074A (GSK'074) is a programmed necrosis inhibitor that displays inhibitory effects on RIP1 and RIP3.

RIPK1-IN-4 is a potent and selective type II kinase receptor interacting protein 1 (RIP1) kinase inhibitor and binds to a DLG-out inactive form of RIP1 (IC50s of 16 nM and 10 nM for RIP1 and ADP-Glo kinase).

RIPA-56 is an inhibitor of RIP1

(E)-Necrosulfonamide ((E)-Necrosulfonamide) is an inhibitor of necroptosis. Blocks mixed lineage kinase domain-like protein (MLKL), a critical substrate of receptor-interacting serine-threonine kinase 3 (RIP3) during necrosis. Prevents MLKL-RIP1-RIP3 necrosome complex from interacting with downstream necrosis effectors. Binds and inhibits gasdermin D. Inhibits pyroptosis.

GSK481 (GSK'481) is a RIP1(Receptor Interacting Protein Kinase1) inhibitor. Inhibition of RIP1 has been shown to hinder cell necrotic death.

GNE684 is a potent inhibitor of receptor interacting protein 1 (RIP1) with average Ki app values of 21 nM for human, 189 nM for mouse, and 691 nM for rat RIP1, respectively [1].

GSK547 (GSK'547) is a highly selective and potent RIP1 kinase inhibitor that disrupts macrophage-mediated adaptive immune tolerance in pancreatic cancer.

AEG40730 is a potent and selective IAP antagonist and a BIR-binding tetrapeptide. AEG40730 binds to cIAP1 and cIAP2, facilitates their autoubiquitination and proteosomal degradation, and causes a dramatic reduction in RIP1 ubiquitination. Treatment with nanomolar concentrations of AEG40730 resulted in the loss of both XIAP and c-IAP1 proteins, albeit with different kinetics.

Tomatine (lycopersicin) is an antiproliferatve agent of breast adenocarcinoma cells.

R-8507 is a small molecule antagonist of the TNF-α type 1 receptor (TNF-αRI). It inhibits the expression of intercellular adhesion molecule-1 (ICAM-1) induced by TNF-α and IL-1β with EC50 values of 2.45 and 3.79 μM, respectively, in an ELISA using A549 lung epithelial cells.{|Gururaja2007|} It also disrupts the interaction of the TNF-αRI with receptor interacting protein 1 (RIP1) and TNF-αR-associated death domain protein (TRADD), preventing internalization of the receptor complex.
