These toxins can interfere with the transmission of the nerve impulse by blocking specific ion channels. The neurotoxins vary in mechanism of action. The concentration of the exposure to the toxin is not indicative of its effects. Several toxins can cause seizures or paralysis in nanomolar ...
Its mechanism of action involves blocking calcium channels, specifically the N-type calcium channels. By inhibiting the influx of calcium ions into neurons, OMEGA-CONOTOXIN MVIIC can modulate neurotransmitter release and synaptic transmission. Storage Conditions: Store in a cool and dry place.

Nicotinic acetylcholine receptors containing the α6 subunit contribute to ethanol activation of ventral tegmental area dopaminergic neurons. Nicotine and alcohol are often co-abused suggesting a common mechanism of action may underlie their reinforcing properties. Both drugs acutely increase act... L Liu...
Here we present the crystal structure and electrophysiological activity profile of a dimeric α D-conotoxin GeXXA. Based on these results, we elucidated the mechanism of action of this dimeric conotoxin. Furthermore, we identified the binding site of this conotoxin on nAChRs, which is clearly ...
Genetically-modified α9-nAChR knockout mice have a phenotype that is markedly different from the analgesic profile of Vc1.1 and similar conotoxins, suggesting that the conotoxin effects are largely independent of α9α10-nAChRs. Furthermore, an alternative mechanism of analgesia by Vc1.1 and ...

Four different conopeptide families are known to target voltage-gated Na+ channels; each has a distinct mechanism of action. As described later, the μ-conotoxins are Na+-channel blockers; the μO-conotoxins inhibit Na+-channel activation; the ι-conotoxins reduce the threshold for activation...
Leconotide (3) (also known as CVID, AM336 and CNSB004), an ω-conotoxin peptide of Conus catus has close similarity to ziconotide both in terms of structure and mechanism of action.19 Intrathecal administration of ziconotide requires expensive equipment and should be performed by only experts....
