TAT-M2NX
Based on 1 Customer Validation
TAT-M2NX (tatM2NX) is a selective inhibitor targeting human TRPM2 channels and exerts inhibitory effects on ischemic stroke. TAT-M2NX reduces H2O2-induced calcium influx via TRPM2 channels. After traumatic brain injury in mice, TAT-M2NX preserves hippocampal long-term potentiation, improves memory function, and reduces infarct volume after middle cerebral artery occlusion, but it shows no effect on female mice. TAT-M2NX can be used in studies related to traumatic brain injury and ischemic stroke.

TRPM2 |
TAT-M2NX (20 mg/kg; retro-orbital injection; single administration) exerts cerebral ischemia-specific neuroprotective effects in male mice: when administered prior to middle cerebral artery occlusion (MCAO), it reduces infarct volume[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:C57Bl/6 (adult 2-4 month, male)[1]
-
Dosage:0.2 mg/kg; 2 mg/kg; 10 mg/kg; 20 mg/kg
-
Administration:i.v.; single dose at 2 hours post-TBI
-
Result:Did not affect hippocampal LTP, with a normalized fEPSP slope of 129.9%, which was not significantly different from control-treated TBI mice.
Preserved hippocampal LTP, with a normalized fEPSP slope of 165.5%, and prevented TBI-induced memory impairment, with freezing behavior of 47.9%.
Preserved hippocampal LTP, with a normalized fEPSP slope of 186.9%, and prevented TBI-induced memory impairment, with freezing behavior of 52.1%.
Prevented TBI-induced memory impairment, with freezing behavior of 62.3%, which was equivalent to the effect of 10 mg/kg.

Animal Model:C57Bl/6 (young adult, 2-3 month old, male, wild-type; TRPM2−/− (young adult, 2-3 month old, male, knockout))[2]
-
Dosage:20 mg/kg
-
Administration:retro-orbital; single dose (20 min prior to MCAO; 3 h after reperfusion)
-
Result:Reduced mean infarct volume to 29.2% in wild-type mice treated 20 min prior to MCAO. Reduced mean infarct volume to 28.3% (24 h post-reperfusion) and 23.8% (96 h post-reperfusion) in wild-type mice treated 3 h after reperfusion. Showed no further reduction in infarct volume (27.3%) in TRPM2−/− knockout mice compared to untreated TRPM2−/− knockout mice (27.3%).
