Dérivés des Purines et Pyrimidines
Les purines possèdent une structure bicyclique, composée d’un cycle à six membres fusionné avec un cycle à cinq membres, tous deux contenant des atomes d’azote à des positions clés. Les dérivés des purines, tels que l’adénine et la guanine, sont essentiels à la formation de l’ADN et de l’ARN. Ces composés ont des applications thérapeutiques dans le traitement du cancer et des maladies virales en inhibant la réplication cellulaire. Les pyrimidines, quant à elles, possèdent une structure monocyclique à six membres avec deux atomes d’azote. Leurs dérivés, tels que la cytosine, la thymine et l’uracile, sont également des composants essentiels de l’ADN et de l’ARN et sont utilisés en chimiothérapie et dans les traitements antiviraux.
Chez CymitQuimica, nous proposons des dérivés des purines et pyrimidines pour la recherche en biologie moléculaire, génomique et le développement de thérapies innovantes.
