Organophosphates inhibit acetylcholinesterase
WitrynaOrganophosphates work by inhibiting the action of AChE. This causes excessive stimulation of muscarinic and nicotinic receptors at the postsynaptic membrane. ACh … WitrynaOrganophosphates are anti-esterase insecticides, and exert their acute effects by causing overstimulation at cholinergic nerve terminals. This process occurs in both insects and humans. Normally, acetylcholinesterase catalyzes the degradation of the neurotransmitter acetylcholine in the synapse (yellow panel below).

WitrynaOrganophosphates inhibit acetylcholinesterase and neurotoxicity is primarily a result of acetylcholine induced hyperactivation in different regions of the brain. Neurotoxicity … WitrynaAcetylcholinesterase inhibitors prevent acetylcholinesterase from doing its job. Some do this for only a little bit, called reversible inhibitors and can be used as medicine in some situations....
WitrynaAcetylcholinesterase, an enzyme of the serine hydrolase family, catalyzes the rapid hydrolysis of certain carboxyl esters. Other acyl esters efficiently transacylate the enzyme with a subsequent, slow deacylation step. Of these, the phosphoryl and phosphonyl esters are perhaps of greatest mechanistic interest since individual enantiomers of … Witryna摘要： Organophosphates are one of the major constituent of herbicides, pesticides, insecticides and nerve gas. Azinophos-methyl, chlorpyrifos, diazinon, fonofos and disulfoton are well-known organophosphate pesticides (OPs) having extensive applications in agriculture, horticulture, pest control, plastic making, flame retardants …
WitrynaSubsequently, mechanism of irreversible acetylcholinesterase inhibition induced by organophosphorus compounds (insecticides and nerve agents), and their specific and nonspecific toxic effects are described, as well as irreversible inhibitors having pharmacological implementation. WitrynaOrganophosphate insecticides (OPs) target acetylcholinesterase (AChE), an enzyme that hydrolyzes acetylcholine and plays an important role in the normal functioning of the central nervous system.
