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.

Caffeine (Pentoxifylline EP Impurity F) is a bitter, white crystalline xanthine alkaloid that acts as a stimulant drug and a reversible acetylcholinesterase inhibitor (1,2,3). Caffeine is found in varying quantities in the seeds, leaves, and fruit of some plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants. In humans, caffeine acts as a central nervous system stimulant, temporarily warding off drowsiness and restoring alertness. Caffeine is a cardiac and respiratory stimulant; diuretic. Caffeine is toxic at sufficiently high doses. Caffeine is a non-competitive inhibitor of acetylcholinesterase (3).<br> Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package<br>References Zubair, U.M., et al.: Anal.
