Derivati delle Purine e Pirimidine
Le purine hanno una struttura biciclica, composta da un anello a sei membri fuso con un anello a cinque membri, entrambi contenenti atomi di azoto in posizioni chiave. I derivati delle purine, come l’adenina e la guanina, sono essenziali per la formazione del DNA e dell’RNA. Questi composti trovano applicazione terapeutica nei trattamenti contro il cancro e le malattie virali, inibendo la replicazione cellulare. Le pirimidine, invece, hanno una struttura monociclica a sei membri con due atomi di azoto. I loro derivati, come la citosina, la timina e l’uracile, sono anch’essi componenti fondamentali del DNA e dell’RNA e vengono utilizzati in chemioterapia e nei trattamenti antivirali.
Presso CymitQuimica, offriamo derivati delle purine e pirimidine per la ricerca in biologia molecolare, genomica e sviluppo di terapie innovative.
