Ferrostatin-1 NLT 98%

Ferrostatin-1 is a potent inhibitor of ferroptosis with an EC₅₀ of 60 nM. IC50 & Target: EC50: 60 nM (Ferroptosis)^[1] In Vitro: Ferrostatin-1 is the most potent inhibitor of erastin-induced ferroptosis in HT-1080 cells (EC₅₀=60 nM). Ferrostatin-1 does not inhibit ERK phosphorylation or arrest the proliferation of HT-1080 cells. Ferrostatin-1 does, however, prevent erastin-induced accumulation of cytosolic and lipid ROS^[1]. Cells pretreated with 0.4 μM Ferrostatin-1 displays significantly reduce intracellular reactive oxygen species (ROS) and nitrogen species (RNS) below basal levels. Additionally, increased intracellular ROS levels are also significantly lowered below basal levels by a 0.4 µM Ferrostatin-1 pretreatment. Ferrostatin-1 treatment for 24 h does not change the expression level of i-NOS in SHSY-5Y cell when compare with vehicle (0.02 % DMSO) treated cells^[2].
