Nigratine (6E11) is a highly specific, non-ATP competitive inhibitor of RIPK1 kinase (IC50=1.6 uM), inhibits necroptosis and ferroptosis.Nigratine inhibits necroptotic cell-death induced by TNF-α in Jurkat-Fadd def cells with IC50 of 4.6 uM.Nigratine is significantly more potent than the specific RIPK1 necroptosis inhibitor, Nec-1s.Nigratine (50 uM) strongly inhibits the ferroptotic cell death induced by excess of glutamate, erastin, and RSL3, in both murine HT22 and human SH-SY5Y cell lines, protects SH-SY5Y human neuroblastoma cell line from cell death triggered by both class I and II-inducers of ferroptosis.Nigratine protects porcine kidney epithelial LLC-PK1 cell line from lipid peroxidation and cell death triggered by RSL3.Nigratine protects human bronchial organoids from necroptosis and ferroptosis.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
