Ziconotide

Ziconotide (also known as SNX-111) is a neurotoxic peptide derived from the cone snail Conus magus comprising 25 amino acids with three disulphide bonds. Other such peptides, collectively termed conotoxins, exist, and some have shown efficacy in binding specific subsets of calcium channels; ziconotide is used in part because it can be synthesized without loss of proper bond formation or structural elements. Ziconotide is used to manage severe chronic pain refractory to other methods, through its ability to inhibit N-type calcium channels involved in nociceptive signalling. Ziconotide was granted FDA approval on December 28, 2004 for marketing by TerSera therapeutics LLC. under the name Prialt. To date, ziconotide is the only calcium channel blocking peptide approved for use by the FDA. It is grouped under the following drug class(es): Peptides. Its therapeutic use is listed as analgesics. The directory classifies it as a commercial API with a peptide source/manufacturing origin. Other names for this substance include omega-Conotoxin M VIIA and Ziconotida. Its PubChem CID is 16135415.
