Additional Information:

NE-100 is potent inhibitor of the sigma receptor (σ) with selectivity for sigma-1 (IC50 = 1.5 nM) over sigma-2 (IC50 = 85 nM) (1,2). This compound suppressed ischemia-induced neuronal cell death in mice via upregulation of GPR78 through the ATF6 pathway resulting in suppression of ER stress-induced cell death in a sigma 1 independent manner (3).
