Home Metabolism Ferroptosis activator iFSP1 For research use only.

iFSP1

iFSP1 is a potent, selective and glutathione-independent inhibitor of ferroptosis suppressor protein 1 (FSP1/AIFM2) with EC50 of 103 nM. iFSP1 selectively induces ferroptosis in GPX4-knockout Pfa1 and HT1080 cells that overexpresses FSP1.Solutions are unstable and should be fresh-prepared.

iFSP1 selectively induces ferroptosis in GPX4-knockout Pfa1 and HT1080 cells that overexpressed FSP1. FSP1 is expressed in most tumour cell lines, and iFSP1 treatment robustly sensitizes these cells to RSL3-induced ferroptosis.[1]
Cell Research Cell lines human cancer cell lines (NCl-H1437, U-373, MDA-MB-436, SW620, MDA-MB-435S, A549, etc.)
Concentrations 0.01 μM - 10 μM, 3 μM
Incubation Time 24 h
Method

Cells are seeded on 96-well plates (2,500 cells per well) and treated with iFSP-1 after plating. Cell viability is assessed 24 h (unless stated otherwise) after treatment using AquaBluer as an indicator of viable cells according to the manufacturer's recommendations.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
