Biological Activity for Necrostatin-1

Necrostatin-1 is an ATP-competitive, allosteric inhibitor of receptor-interacting protein kinase 1 (RIPK1) (EC50 = 182 nM). Blocks non-apoptotic cell death via inhibition of a specific cellular pathway, necroptosis, which leads to necrosis (EC50 = 494 nM). Reduces ischemic brain injury in a mouse model of stroke.

Necroptosis-related studies.
By MARINA KOUTSIOUMPA on 10/13/2022
Assay Type: In Vitro
Species: Human

Combinatorial treatments of Necrostatin-1 with other chemotherapeutic drugs were performed to elucidate the dependance of the latter on the induction of necroptosis. Results were consistent.

good necroptosis inhibitor.
By Anonymous on 06/28/2020
Assay Type: In Vitro
Species: Human
Cell Line/Tissue: Caco-2

100nM of Nec-1 was used to inhibit RIPK1 after administration cells with TNFa, zVADfmk, and smac inhibitors to induce necroptosis, then cell death rate was measured with a commercial kit.
