Project of recently sequenced conotoxin in to the suitable superfamily utilizing a computational strategy could offer an efficient way of obtaining or adding precious preliminary information over the natural and pharmacological functions of these toxins. (columbiagypsy.net)
Conotoxins Toxins from cone shells (Conus spp. (forexsignalx.com)
Conus2
A wide variety of natural CCB were identified in animal venoms containing neuroactive or neuroprotective peptides, including the conotoxins from Conus snails [ 12 ]. (biomedcentral.com)
1 History Conotoxins are elements of the neurotoxic peptides isolated through the venom from the sea cone snail from the Genus Conus. (columbiagypsy.net)
Analgesic1
Antagonism of the α9α10 nicotinic acetylcholine receptor (nAChR) subtype (absent in brain) is thought to underlie analgesic efficacy of peptide α-conotoxins. (nih.gov)
Calcium6
There are many known N-type calcium channel blockers that function to inhibit channel activity, although the most notable blockers are ω-conotoxins. (wikipedia.org)
Studies have shown that the intrathecal injection of the calcium channel inhibitor ziconotide, to block the N-type calcium channels, have produced alleviation of intractable pain. (wikipedia.org)
Blockade of the N-type calcium channel is a potential therapeutic strategy for the treatment of alcoholism. (wikipedia.org)

(wikipedia.org)
Calcium channel blockers such as conotoxins have shown a great potential to reduce brain and spinal cord injury. (biomedcentral.com)
Synthetic version1
King's team produced a synthetic version to see if the molecule could be manufactured as a drug. (scientificamerican.com)
Shown1
And earlier this year at the American Chemical Society meeting in Dallas, Tex., he unveiled five more ring-shaped conotoxins that have also shown durability in early studies. (scientificamerican.com)
Potential1
O'Rourke wrote in that, "Compared to a one-yard strategy, approaches involving two yards may be more expensive but offer potential offsetting benefits. (biofrontierlab.com)
Pain1
Tetrodotoxin: A New Strategy to Treat Visceral Pain? (mdpi.com)
Effective2
Such a strategy may provide effective treatment that circumvents toxicity of centrally acting agonists at nAChR. (nih.gov)
In this eBriefing, learn strategies for effective grant writing, specifically applied to fellowship applications in biomedical fields. (nyas.org)
Important1
Despite their powerful, PMPA (NAALADase inhibitor) supplier profile-based SVM strategies have one important drawback- a thorough training requirement. (columbiagypsy.net)
Multiple disulfide1
These conotoxins display well-defined, protein-like structures, which are stabilised through multiple disulfide bond frameworks. (sciencedaily.com)
Bioactive peptides2
Conotoxins are bioactive peptides found in the venom that marine cone snails produce for prey capture and defense. (sciencedaily.com)
Amongst the 500-700 species of cone snails, they each produce their own cocktail of 200 bioactive peptides, thus providing the snails with a complex venom cocktail directed against specific prey. (sciencenordic.com)
Cone snail2
The marine predatory cone snail is well-known for its effective envenomation strategy, which helps the relatively slow-moving animal to catch their prey such as fish or molluscs and to defend itself. (sciencedaily.com)
Besides conotoxins, cone snail venom also consists of compounds collectively known as small-molecules, about which we know very little. (sciencenordic.com)
Amino acids1
Conotoxins are small peptides consisting of around 10-35 amino acids and exists in over 100,000 variants, with various targets. (sciencenordic.com)
Venom3
These venom components ("conotoxins, conopeptides") have been widely studied in many laboratories, leading to pharmaceutical agents and probes. (nih.gov)
Underneath the shell a complex venom can be found, it is produced in the venom gland connected to the harpoon like tooth it uses to sting with. (sciencenordic.com)
Conotoxins are also active on human receptors (e.g., ion channels), which is of particular interest as they thus can be used as tools to study pain pathways in humans. (sciencedaily.com)
Commonly, conotoxins work as antagonists on different ion channels and receptors in the nerves, which means they inhibit the normal signals induced by neurotransmitters. (sciencenordic.com)
Research2
Current research focuses now on conotoxins that could already target nerve endings outside the spinal cord, which would facilitate administration. (sciencedaily.com)
Biomedical research produces many important benefits for society, but it can also lead to harmful results. (nih.gov)

(wikipedia.org)
Conotoxins can furthermore be functionalised and provide outstanding leads for new molecular probes: In another paper published in the "Australian Journal of Chemistry," the researchers developed a new methodology to label conotoxins and use them to visualise ion channels in cells.
