Lewis %J Marine Drugs %D 2006 %I MDPI AG %R 10.3390/md403193 %X Highly selective N-type voltage-gated calcium (CaV) channel inhibitors from cone snail venom (the ¦Ø-conotoxins) have emerged as a new class of therapeutics for the treatment of chronic and neuropathic pain. Earlier in 2005, Prialt (Elan) or synthetic ¦Ø-conotoxin MVIIA, was the first ¦Ø-conotoxin to be approved by Food and Drug Administration for human use. This review compares the action of three ¦Ø-conotoxins, GVIA, MVIIA and CVID, describing their structure-activity relationships and potential as leads for the design of improved N-type therapeutics that are more useful in the treatment of chronic pain. %K ¦Ø-conotoxin %K Structure-Activity relationship %K pain %U http://www.mdpi.com/1660-3397/4/3/193
