“…Homoanatoxin-a is a methyl derivate of anatoxin-a with similar pharmacological and toxicological properties (Wonnacott et al, 1992), and it has been implicated in dog deaths in New Zealand (Wood et al, 2007). In addition to being a nicotinic agonist, homoanatoxin-a can increase the release of acetylcholine from peripheral cholinergic nerves through opening of endogenous voltage-dependent neuronal L-type Ca 2 channels (Aas et al, 1996).…”

“…Foi observado que o efeito fisiológico de ambas é muito semelhante 13 . Outros estudos demonstram que a Homoanatoxina-a produz um aumento da liberação de acetilcolina nas terminações dos nervos colinérgicos periféri-cos, por meio da abertura de canais de Ca ++ dependentes de voltagem tipo L 36 . Philips et al 37 , realizaram ensaios de competição pelo receptor nicotínico em cérebro de rato, entre Nicotina e α-Bungarotoxina marcadas e alguns análogos sintéticos da Anatoxina-a (Homoanatoxinaa, Propilanatoxina e Isopropilanatoxina).…”
