Derivados de Purinas y Pirimidinas
Las purinas tienen una estructura bicíclica, formada por un anillo de seis miembros fusionado con un anillo de cinco, ambos con átomos de nitrógeno en posiciones clave. Los derivados de purinas, como la adenina y la guanina, son fundamentales en la formación del ADN y ARN. Estos compuestos tienen aplicaciones terapéuticas en tratamientos contra el cáncer y enfermedades virales, al inhibir la replicación celular. Las pirimidinas, por otro lado, tienen una estructura monocíclica de seis miembros con dos átomos de nitrógeno. Sus derivados, como la citosina, timina y uracilo, también son componentes esenciales del ADN y ARN y se utilizan en la quimioterapia y tratamientos antivirales.
En CymitQuimica disponemos de derivados de purinas y pirimidinas para investigación en biología molecular, genómica y desarrollo de terapias innovadoras.
