Tat-M2NX TFA

Tat-M2NX, a peptide antagonist of transient receptor potential melastatin 2 (TRPM2), blocks hydrogen peroxide-induced calcium influx in HEK293 cells expressing human TRPM2 at concentrations between 25 to 100 μM. In male mice models of stroke caused by middle cerebral artery occlusion (MCAO), Tat-M2NX (20 mg/kg) demonstrates efficacy in reducing brain infarct volume when applied before or 3 hours-post occlusion, yet it shows no such effect in female mice.
