Messieurs Jean Legault et Andr\u00e9 Pichette ont d\u00e9couvert des propri\u00e9t\u00e9s antitumorales aux huiles extraites du sapin baumier<\/figcaption><\/figure>L’alpha-humul\u00e8ne, une substance active extraite de l’huile essentielle d’un conif\u00e8re de la for\u00eat bor\u00e9ale (le sapin baumier) offrirait de r\u00e9elles possibilit\u00e9s dans le traitement de certains cancers. Cette d\u00e9couverte, \u00e9lev\u00e9e au rang des dix d\u00e9couvertes de l’ann\u00e9e 2001 par le magazine Qu\u00e9bec-Science, est le fruit du travail de deux chimistes, professeurs-chercheurs de l’Universit\u00e9 du Qu\u00e9bec \u00e0 Chicoutimi, Jean Legault et Andr\u00e9 Pichette.<\/p>\n

Plusieurs extraits du feuillage de diff\u00e9rents conif\u00e8res ont \u00e9t\u00e9 \u00e9tudi\u00e9s afin d’en \u00e9valuer le potentiel antitumoral. \u00c0 la lumi\u00e8re de ces r\u00e9sultats, il a \u00e9t\u00e9 d\u00e9termin\u00e9 que les extraits de sapin baumier poss\u00e9daient un potentiel antitumoral contre diff\u00e9rentes lign\u00e9es de cellules canc\u00e9reuses et qu’ils d\u00e9montraient une faible toxicit\u00e9 chez l’animal. <\/p>\n

Certains extraits de sapin ont \u00e9t\u00e9 analys\u00e9s par diff\u00e9rentes approches analytiques afin de d\u00e9terminer le ou les produits naturels responsables de l’activit\u00e9 biologique. Ainsi, il a \u00e9t\u00e9 possible de d\u00e9terminer que l’huile essentielle, un type d’extrait pr\u00e9sentant un bon potentiel antitumoral, \u00e9tait compos\u00e9e d’une quinzaine de compos\u00e9s. Le fractionnement de l’huile essentielle a permis d’identifier qu’un compos\u00e9, l’alpha-humul\u00e8ne, \u00e9tait responsable de l’activit\u00e9 antitumorale. <\/p>\n

Les travaux de recherche se poursuivent en collaboration avec diff\u00e9rents groupes de recherche afin de d\u00e9terminer le potentiel antitumoral de compos\u00e9s apparent\u00e9s. Ces compos\u00e9s apparent\u00e9s peuvent \u00eatre des produits naturels de la m\u00eame famille ou encore des d\u00e9riv\u00e9s de l’alpha-humul\u00e8ne.<\/p>\n

Les chercheurs prennent cependant la pr\u00e9caution de souligner qu’il s’agit des premiers pas vers la d\u00e9couverte d’un nouveau m\u00e9dicament et incitent \u00e0 la prudence quant \u00e0 l’interpr\u00e9tation: \u00abnous ne pouvons encore dire si on tient l’amorce d’un traitement contre le cancer. Les 6 \u00e0 12 prochains mois seront d\u00e9terminants. Des r\u00e9sultats positifs \u00e0 nos exp\u00e9riences seraient extr\u00eamement int\u00e9ressants et prometteurs\u00bb.<\/p>\n","protected":false},"excerpt":{"rendered":"
