What is affected by diisopropyl fluorophosphate?

Acute exposure to diisopropyl fluorophosphate (DFP) causes irreversible inhibition of acetylcholinesterase activity, leading to various behavioral and autonomic sequelae including hypothermia, reduced motor activity, and other neurological dysfunctions.

What kind of inhibitor is diisopropyl fluorophosphate?

acetylcholinesterase inhibitor
Diisopropylfluorophosphate (DFP) is a potent acetylcholinesterase inhibitor commonly used in toxicological studies as an organophosphorus nerve agent surrogate.

Is Isoflurophate an organophosphate?

Isoflurophate is an organophosphorus compound that acts as an irreversible cholinesterase inhibitor. As such, it displays parasympathomimetic effects.

What is the function of diisopropyl fluorophosphate?

Diisopropyl fluorophosphate is a dialkyl phosphate. Isoflurophate is a synthetic dialkyl phosphate compound and acetylcholinesterase inhibitor that is used as a pesticide. It is characterized as a colorless or faintly yellow oily liquid with a weak fruity odor, and exposure occurs by inhalation, ingestion, or contact.

What are the effects of sarin gas?

Exposure to high doses of sarin can result in tremors, seizures, and hypothermia. A more severe effect of sarin is the build-up of ACh in the central nervous system (CNS) which causes paralysis and ultimately peripherally-mediated respiratory arrest, leading to death.

What is diisopropyl fluorophosphate used for?

Diisopropyl fluorophosphate is a parasympathomimetic drug irreversible anti-cholinesterase and has been used in ophthalmology as a miotic agent in treatment of chronic glaucoma, as a miotic in veterinary medicine, and as an experimental agent in neuroscience because of its acetylcholinesterase inhibitory properties and …

Where are acetylcholinesterase found?

Acetylcholinesterase (AChE) is a cholinergic enzyme primarily found at postsynaptic neuromuscular junctions, especially in muscles and nerves. It immediately breaks down or hydrolyzes acetylcholine (ACh), a naturally occurring neurotransmitter, into acetic acid and choline.

What happens if you block acetylcholinesterase?

The inhibition of the enzyme leads to accumulation of ACh in the synaptic cleft resulting in over-stimulation of nicotinic and muscarinic ACh receptors and impeded neurotransmission. The typical symptoms of acute poisoning are agitation, muscle weakness, muscle fasciculations, miosis, hypersalivation, sweating.

Why is acetylcholinesterase necessary?

[1] The primary role of AChE is to terminate neuronal transmission and signaling between synapses to prevent ACh dispersal and activation of nearby receptors. AChE is inhibited by organophosphates and is an important component of pesticides and nerve agents.
