iFSP1, a potent, selective, and glutathione-independent ferroptosis suppressor protein 1 (FSP1) (AIFM2) inhibitor with an EC50 of 103 nM, sensitizes diverse human cancer cell lines to ferroptosis inducers like (1S,3R)-RSL3. It uniquely triggers ferroptosis in GPX4-knockout cells overexpressing FSP1.

FSP1-IN-1 (compound 39) is a potent FSP1 inhibitor with an IC50 of 35 nM. It enhances lipid peroxide accumulation induced by RSL3 and increases cancer cell susceptibility to ferroptosis.

icFSP1 is a mitochondria-associated apoptosis-inducing factor regulator with antitumor activity for the study and treatment of tumor diseases.

icFSP1, an inhibitor of ferroptosis suppressor protein 1 (FSP1), promotes condensation and phase separation of FSP1 in cellular environments at 2.5 µM concentration but does not affect FSP1's enzymatic function in cell-free assessments (IC50 = > 30 µM). This compound selectively induces ferroptosis in HT-1080 fibrosarcoma cells in a dose-dependent manner. Furthermore, in vivo studies show that icFSP1 administered at 50 mg kg significantly reduces both the volume and weight of tumors in a B16 F10 murine melanoma model utilizing human FSP1-overexpressing, Gpx4- -Fsp1- - B16 F10 cells.

viFSP1, a species-independent FSP1 inhibitor, effectively induces ferroptosis in FSP1-dependent cells by targeting the highly conserved NAD(P)H binding pocket of FSP1, directly inhibiting its activity. This action results in lipid peroxidation and exhibits anticancer activity [1].

Sinefungin (Adenosyl-Ornithine) is an effective inhibitor of virion mRNA(guanine-7-)-methyltransferase, mRNA(nucleoside-2'-)-methyltransferase, and viral multiplication. Sinefungin is a SET7 9 inhibitor and ameliorates renal fibrosis by inhibiting H3K4 methylation.

Coumarin-quinone conjugate is a fluorescent substrate for NADH:ubiquinone oxidoreductases.1It is comprised of a coumarin fluorophore conjugated to a ubiquinone analog that can be reduced by NADH:ubiquinone oxidoreductases. It has been used to measure the kinetic parameters of apoptosis-inducing factor mitochondria-associated 2/ferroptosis suppressor protein 1 (AIFM2/FSP1). 1.Doll, S., Freitas, F.P., Shah, R., et al.FSP1 is a glutathione-independent ferroptosis suppressorNature575(7784)693-698(2019)

FSEN1 is a novel and highly effective non-competitive FSP1 inhibitor with an IC50 value of 313 nM. FSEN1 induces ferroptosis in cancer cells by inhibiting FSP1. FSEN1 can be used to prevent and treat cancer.

Coumarin–quinone conjugate, a fluorescent substrate for NADH:ubiquinone oxidoreductases, consists of a coumarin fluorophore and a ubiquinone analog. It can be utilized to measure the kinetic parameters of AIFM2/FSP1 in research related to ferroptosis [1].
