Pyridaben-d13 is the deuterium labeled Pyridaben[1]. Pyridaben is a mitochondrial electron transport inhibitor (METI) acaricide that promotes the formation of damaging oxygen and nitrogen radicals. Pyridaben selectively inhibits complex I (NADH dehydrogenase) with an IC50 value of 2.4 nM (assay sites: rat liver and bovine heart mitochondria). Pyridaben also significantly inhibits rat mitochondrial mtNOS function[2][3]. | [References]
