Purines and Pyrimidine Derivatives
Purines have a bicyclic structure, consisting of a six-membered ring fused to a five-membered ring, both containing nitrogen atoms in key positions. Purine derivatives, such as adenine and guanine, are essential for the formation of DNA and RNA. These compounds have therapeutic applications in cancer and viral disease treatments by inhibiting cell replication. Pyrimidines, on the other hand, have a monocyclic six-membered structure with two nitrogen atoms. Their derivatives, such as cytosine, thymine, and uracil, are also essential components of DNA and RNA and are used in chemotherapy and antiviral treatments.
At CymitQuimica, we offer purine and pyrimidine derivatives for research in molecular biology, genomics, and the development of innovative therapies.
