For this purpose human erythrocyte AChE (EC 3.1.1.7) was inhibited (30 min) by chlorfenvinphos, dichlorvos, dicrotophos, heptenophos, mevinphos, monocrotophos, paraoxon, phosphamidon, trichlorfon, malaoxon, omethoate, oxydemeton-methyl or methamidophos by 85-98% of control.

Low doses of the acetylcholinesterase inhibitors, mevinphos and physostigmine, reduce hippocampal inhibitory phenomena, measured in terms of the duration of the poststimulus inhibitory pause seen in individual hippocampal neurones in the pigeon.

A single dose of sarin or repeated doses of metrifonate or mevinphos, have produced only transient adverse effects at doses causing substantial acetylcholinesterase inhibition.

At the equi-effective level which respects the toxicity of the oxime and is therefore more important for practical use, it is a therapeutically weaker reactivator of acetylcholinesterase than HI-6.

The enhanced inhibition of total ChE due to CPZ depended in most peripheral organs on the effect on pseudoChE (as measured by a spectrophotometric method), except in the case of skeletal muscle in which potentiation of PhS effect was observed on true acetylcholinesterase (AcChE).
CPZ was found to potentiate slightly the effects of Mevinphos but did not interact with Carbaryl, Diazinon or Azinphos.

Values were simultaneously generated for the ED50 (milligrams per kilogram) for both cholinesterase and acetylcholinesterase.
Lethality was greatest with mevinphos, followed by parathion, methyl parathion, diazinon, and azinphosmethyl.

The ratio of inhibitory powers for acetylcholinesterase and NTE represents the crucial guideline for the aetiological attribution of OP-induced peripheral neuropathy.
In this article, we mainly discuss OP pesticide poisoning, particularly when caused by chlorpyrifos, dichlorvos, isofenphos, methamidophos, mipafox, trichlorfon, trichlornat, phosphamidon/mevinphos and by certain carbamates.

Neuropharmacology. 2006 Dec;51(7-8):1109-19. Epub 2006 Sep 18.

Taking advantage of the absence in an in vitro system of acetylcholinesterase, the pharmacological target of organophosphate compounds, the present study evaluated the hypothesis that the repertoire of cholinergic receptor-independent cellular events that underlie fatal organophosphate poisoning entails induction of mitochondrial dysfunction, followed by bioenergetic failure that leads to necrotic cell death because of ATP depletion.

Shock. 2007 May;27(5):559-64.

As inhibitors of acetylcholinesterase, clinical presentations of poisoning from organophosphate compounds are generally believed to entail overstimulation by the accumulated acetylcholine on muscarinic receptors at peripheral and central synapses.
