Tralopyril
Based on 1 Customer Validation
Tralopyril is an orally active, blood-brain barrier-penetrating antifouling insecticide and endocrine disruptor. By interfering with the thyroid hormone system and mitochondrial oxidative phosphorylation, Tralopyril downregulates the transcription of genes such as TRHR, Nkx2.1, TRα and induces ferroptosis. Tralopyril disrupts amino acid, energy and lipid metabolism, exhibits significant skeletal and reproductive toxicity, and causes developmental damage. Tralopyril has a long half-life in vivo and wide tissue distribution, posing potential risks to aquatic organisms and human health. Tralopyril shows species specificity in in vitro liver microsomal metabolism, exerts lethal effects on target insects and laboratory animals, and is commonly used in studies of chlorfenapyr poisoning and related toxic mechanisms.

Biological Activity
Tralopyril potently inhibits growth, ATP production, and effective quantum yield in Chlamydomonas reinhardtii cells[1].
Tralopyril (200 μM; 0, 5, 15, 30, 45, 60 min) exhibits low metabolic clearance in human and monkey liver microsomes, moderate clearance in mouse, rat, and dog liver microsomes, with interspecies differences in in vitro metabolic stability[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Tralopyril (45 mg/kg; p.o.), the in vivo metabolite of chlorfenapyr, has a significantly longer half-life (5.39 h), higher AUC0-t, and higher Cmax than chlorfenapyr, and it distributes widely across all mouse tissues including the brain[3].
Tralopyril (27 mg/kg; p.o.; single dose) has an oral LD50 of 27 mg/kg in male rats, indicating acute lethal toxicity via this route[4].

-
Animal Model:BALB/c (male, 8-9 weeks old, 22-25 g, SPF-grade)[3]
-
Dosage:45 mg/kg (generated in vivo via metabolic conversion of chlorfenapyr)
-
Administration:p.o.
-
Result:Exhibited a half-life of 5.39 h, area under the curve (AUC(0-t)) of 15912.77 μg/L*h, peak concentration (Cmax) of 4212.48 μg/L, and time to peak concentration (Tmax) of 0.42 h.
Was widely distributed across all tested tissues (heart, liver, spleen, lung, kidney, brain, skeletal muscle, stomach, intestine, plasma), including crossing the blood-brain barrier.
Was cleared more slowly than chlorfenapyr, with detectable levels in most tissues for up to 24 hours post-administration.
