“…A 25-amino acid Ca V 2.2 channel pore-blocking toxin, v-conotoxin MVIIA, has been isolated from the Conus magus snail and mediates potent analgesia after intrathecal delivery to rodents (Chaplan et al, 1994;Bowersox and Luther, 1998;Wang et al, 2000;Scott et al, 2002) and human patients with persistent cancer pain (Atanassoff et al, 2000;Miljanich, 2004;Staats et al, 2004;Thompson et al, 2006;Wallace et al, 2006;Ver Donck et al, 2008). This fits with the important role of Ca V 2.2 channels in neurotransmitter release from afferent terminals.…”

“…28,63,65,69 Com sua seletividade com relação ao alvo molecular, o ziconotídeo bloqueia, em concentrações picomolares, o canal de cálcio do tipo N das fibras nociceptivas tipo A-δ e tipo C nas lâminas I e II da raiz dorsal do cordão nervoso de mamíferos, apresentando analgesia em vários modelos de nocicepção. 70,71 O extraordinário potencial antinociceptivo das ω-contoxinas (o ziconotídeo é mil vezes mais potente do que a morfina) emerge de duas propriedades: a particular sensibilidade das fibras tipo C a essas substâncias, como mencionado, e a ausência de tolerância ao tratamento com esses peptídeos. Em contraste com os opioides, que são agonistas de receptores acoplados à proteína G e que levam à diminuição no número de receptores após tratamento continuado e à consequente dessensibilização, o tratamento com ziconotídeo não induz tolerância após uso crônico.…”

“…Ziconotide is a selective, reversible blocker of neuronal N-type voltage-sensitive calcium channels that produces potent antinociceptive effects by blocking neurotransmission from primary nociceptive afferents [42]. This drug and second generation non-peptide drugs are considered to be some of the best new drugs to treat chronic pain [43].…”
