Does ziconotide bind to N-type calcium channels?
['Since this region partially overlaps with residues previously implicated in block of the channel by omega-conotoxin GVIA, we assessed the effects of mutations in the putative EF hand domain on channel block by omega-conotoxin GVIA and the structurally related omega-conotoxin MVIIA. Both of the toxins irreversibly block the activity of wild type alpha(1B) N-type channels. ', 'Despite their high sequence homology, the peptide neurotoxins omega-conotoxin MVIIA and MVIIC selectively block N- and P/Q-type calcium channels, respectively. ', ' Binding assay for both N- and P/Q-type calcium channels showed that amino acid residues restricted to the N-terminal half are important for the recognition of N-type channels, whereas essential residues for P/Q-type channel recognition are widely spread over the whole omega-conotoxin molecule.', 'Ziconotide is a novel peptide that blocks the entry of calcium into neuronal N-type voltage-sensitive calcium channels, preventing the conduction of nerve signals.', 'Ziconotide is a selective, potent and reversible blocker of neuronal N-type voltage-sensitive calcium channels (VSCCs).', 'The therapeutic benefit of ziconotide derives from its potent and selective blockade of neuronal N-type voltage-sensitive calcium channels.', 'Interactions of intrathecally administered ziconotide, a selective blocker of neuronal N-type voltage-sensitive calcium channels, with morphine on nociception in rats.', 'Ziconotide, a new N-type calcium channel blocker, administered intrathecally for acute postoperative pain.', 'Ziconotide, an intrathecally administered N-type calcium channel antagonist for the treatment of chronic pain.', 'Thus, ziconotide is the first of a new class of agents--N-type calcium channel blockers, or NCCBs.', 'Ziconotide, formerly known also as SNX- 111, represents a new class of agents, the N-type calcium channel blockers.', 'The selective N-type calcium channel blocker ziconotide ameliorates severe chronic pain but has a narrow therapeutic window and requires intrathecal administration.', 'A selective N-type calcium channel inhibitor, ziconotide (Prialt), is a neuroactive peptide recently marketed as a novel nonopioid treatment for severe chronic pain.', 'As the clinically available analgesics, pregabalin (alpha2delta-subunit calcium channel ligand), ziconotide (N-type calcium channel blocker), mexiletine (sodium channel blocker), and duloxetine (serotonin and norepinephrine reuptake inhibitors) were evaluated in these neurochemically-induced allodynia models.', 'The present investigation was designed to assess the safety and analgesic efficacy of ziconotide, a new N-type calcium channel blocker, when administered intrathecally to patients with acute postoperative pain.', 'Inhibition of the N-type calcium channel by intrathecal administration of the channel-specific blocker omega-conotoxin MVIIA (ziconotide) is efficacious in the treatment of severe chronic pain.', 'Ziconotide is a powerful analgesic drug that has a unique mechanism of action involving potent and selective block of N-type calcium channels, which control neurotransmission at many synapses.', 'In conclusion, present findings provide implication that the spinal anti-nociceptive mechanistic site of pregabalin is different from that of ziconotide, mexiletine, and duloxetine, and pregabalin could have a broader anti-nociceptive mechanism other than N-type calcium channel blockade.', 'Ziconotide (SNX-111), a selective blocker of neuronal N-type voltage-sensitive calcium channels, is antinociceptive when it is administered intrathecally.', 'Effects of intrathecal administration of ziconotide, a selective neuronal N-type calcium channel blocker, on mechanical allodynia and heat hyperalgesia in a rat model of postoperative pain.', 'A state-dependent Ca(V)2.2 inhibitor may provide an improved therapeutic window over ziconotide, the peptidyl Ca(V)2.2 inhibitor used clinically.
