Neonicotinoid insecticide toxicology: mechanisms of selective action.
The neonicotinoids have outstanding potency and systemic action for crop protection against piercing-sucking pests, and they are highly effective for flea control on cats and dogs. Expand
Selective toxicity of neonicotinoids attributable to specificity of insect and mammalian nicotinic receptors.
Knowledge reviewed here of the functional architecture and molecular aspects of the insect and mammalian nAChRs and their neonicotinoid-binding site lays the foundation for continued development and use of this new class of safe and effective insecticides. Expand

It is found that fipronil contains a trifluoromethylsulfinyl moiety that is unique among the agrochemicals and therefore presumably important in its outstanding performance, and unexpectedly undergoes a novel and facile photoextrusion reaction on plants upon exposure to sunlight. Expand
Neuroactive insecticides: targets, selectivity, resistance, and secondary effects.
Primary toxic effects in mammals from off-target serine hydrolase inhibition include organophosphate-induced delayed neuropathy and disruption of the cannabinoid system. Expand

Inhibition of PP2A activity may account for the diverse effects and toxicity of cantharidin and its analogs, including the herbicide endothall, in mammals and possibly plants. Expand
Protein phosphatase 2A and its [3H]cantharidin/[3H]endothall thioanhydride binding site. Inhibitor specificity of cantharidin and ATP analogues.
CA and three analogues inhibited PP2A and protein phosphatase 1 (PP1) but not PP2B or PP2C, which indicates the potential use of CA analogues as pharmacological probes to investigate cellular processes that are regulated by reversible protein phosphorylation in vivo. Expand
Structural model for gamma-aminobutyric acid receptor noncompetitive antagonist binding: widely diverse structures fit the same site.
Six NCAs plus t-butylbicyclophosphorothionate fit the 2' to 9' pore region forming hydrogen bonds with the T6' hydroxyl and hydrophobic interactions with A2', T6', and L9' alkyl substituents, thereby blocking the channel. Expand
