In the present study, the effects of malathion and malathion derivatives on histamine and beta-hexosaminidase release by RBL-1 cells, rat peritoneal mast cells (RPMC), and human peripheral blood basophils (HPBB) and cutaneous mast calls were examined. One hour of incubation
Jonathan A Doorn et al.
Chemical research in toxicology, 16(8), 958-965 (2003-08-20)
The present study was undertaken to test the hypothesis that acetylcholinesterase (AChE) inhibition by isomalathion stereoisomers proceeds with different primary leaving groups for (1R)- and (1S)-isomers. Consistent with results obtained with enzyme from other species, AChE from Torpedo californica (TcAChE)

Journal of biochemical and molecular toxicology, 19(6), 406-414 (2006-01-20)
The organophosphorothioate (OPT) pesticide malathion (MAL) in mammals is readily hydrolyzed by mammalian carboxylesterases (CE). The reaction competes with the CYP-catalyzed formation of malaoxon (MOX), the toxic metabolite. Alterations or individual variations in CE activity may result in increased MOX
S Jianmongkol et al.
Toxicology and applied pharmacology, 139(2), 342-348 (1996-08-01)
The cholinergic toxicity of malathion is exacerbated by its isomerization product, isomalathion, which inhibits detoxifying carboxylesterases as well as target acetylcholinesterase (AChE). Previous work has shown that the four stereoisomers of isomalathion, (1R, 3R), (1R, 3S), (1S, 3R), and (1S
J Błasiak et al.

Malathion [S-(1,2-dicarboethoxyethyl)O,O-dimethyl phosphorodithioate] is a commonly used organophosphorus insecticide reported to be genotoxic both in vivo and in vitro, but the reports are conflicting. In order to elucidate the genotoxic potency of the main compounds present in commercial preparations of
