Kitazine is an organophosphorus chemical fungicide. It is mainly used to control rice blast and has a certain effect on rice Sclerotinia sclerotiorum, sheath blight, corn leaf spot, and spot disease.
Dibutyl 3-hydroxybutyl phosphate is a compound produced from the metabolism of the organophosphorus solvent, tributyl phosphate (TBP). Incubation of goldfish liver microsomes in the presence of NADPH has been shown to convert TBP into dibutyl-3-hydroxybutyl phosphate and dibutyl phosphate. Dibutyl-3-hydroxybutyl phosphate has also been produced during radiolysis of TBP.
The endocannabinoids, 2-arachidonoyl glycerol (2-AG) and arachidonoyl ethanolamide (AEA), are biologically active lipids that regulate diverse neurological and metabolic functions by activating the cannabinoid receptors, central cannabinoid (CB1) and peripheral cannabinoid (CB2). Monoacylglycerol lipase (MAGL) and fatty acid amide hydrolase (FAAH) hydrolyze 2-AG and AEA, respectively, thus terminating their biological function. IDFP is an organophosphorus compound that dually inhibits MAGL and FAAH with IC50 values of 0.8 and 3 nM, respectively. At 10 mg/kg, IDFP elevates brain levels of 2-AG and AEA more than 10-fold, and decreases levels of arachidonic acid by a similar magnitude.
FP-biotin is a potent organophosphorus toxicant, ideal for identifying novel biomarkers of organophosphorus toxicant exposure. It measures FAAH, ABHD6, and MAG-lipase activity, specifically in plasma studies, due to the efficient purification of biotinylated peptides through binding to immobilized avidin beads.
Cyanophos is a cholinesterase inhibitor used as an insecticide and avicide; for example, against rice stem borers and house flies. It is part of the chemical class of organophosphorus compounds, and is a yellow to reddish-yellow transparent liquid.
