Dimpylate (diazinon) is a nonsystemic organophosphate insecticide, an inhibitor of the enzyme acetylcholinesterase (AChE), which hydrolyzes the neurotransmitter acetylcholine (ACh) in cholinergic synapses and neuromuscular junctions. This results in abnormal accumulation of ACh in the nervous system. Dimpylate was first registered for use in the USA in 1956. It was developed as an insecticide, acaricide, and nematicide for use on a variety of pests for control of soil insects and pests of fruit, vegetables, and forage and field crops. It had been used extensively in home and garden applications, in formulations designed to prevent such pests as crickets or cockroaches from infesting homes or offices, and in pet collars. Due to the emerging health and ecological risks posed by diazinon, manufacturers agreed to phase out and cancel all residential products. Manufacturing of indoor use products containing dimpylatewas discontinued in 2001; manufacture of non-agricultural outdoor use products containing dimpylate was discontinued in 2003.

Route of Administration:
Topical
The Ellman assay was used to test AchE inhibition activity. The assay is based on chromophores generated in situ after enzymatic cleavage of acetylthiocholine and the resulting thiocholine with Ellman’s reagent, DTNB (5,50-dithio-bis-2-nitrobenzoic acid). The plates were incubated at room temperature and the enzymatic activity was determined by spectrophotometric reading at 412 nm.
