Trimedoxime
Trimedoxime (TMB-4) is a blood-brain barrier-permeable cholinesterase reactivator. Trimedoxime reactivates cholinesterase inhibited by paraoxon, sarin, tabun and other agents, restricts the breakdown of acetylcholine and alleviates excessive cholinergic stimulation. Trimedoxime reduces mortality and prolongs survival time. Trimedoxime exhibits reactivation efficacy against AChE in rat tissues. Trimedoxime can be used in research related to organophosphate (paraoxon) poisoning and tabun poisoning.

生物活性
Trimedoxime (7.5 mg/kg; i.m.; single dose) significantly reactivates acetylcholinesterase (AChE) inhibited by tabun in rat blood and diaphragm, with reactivation rates of 17.5% and 34.7%, respectively, but exerts extremely weak reactivation on this enzyme in rat brain (only 2.8%), and reduces the acute lethal effect of tabun in mice[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:Wistar (male, 200-250 g, organophosphate poisoning model via intraperitoneal paraoxon exposure)[1]
-
Dosage:25 µM/rat
-
Administration:i.p.; single dose
-
Result:Reduced 48-hour mortality to 38% in rats exposed to 1 µmol/rat paraoxon.
Reduced 48-hour mortality to 76% in rats exposed to 10 µmol/rat paraoxon.
Reduced 48-hour mortality to 83% in rats exposed to 15 µmol/rat paraoxon.
Lowered the relative risk of death to 0.36 (95% confidence interval, 0.26 to 0.50) compared to paraoxon-only controls.
