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.

CAS:Ethyl 3-aminopyrazole-4-carboxylate is an anticancer drug that inhibits the growth of cancer cells by inhibiting protein synthesis. It has been shown to inhibit the activity of dpp-iv and pde5, which are enzymes involved in cellular proliferation. Ethyl 3-aminopyrazole-4-carboxylate has also been shown to have antiinflammatory properties, which may be due to inhibition of prostaglandin synthesis. Ethyl 3-aminopyrazole-4-carboxylate is a multinuclear compound that reacts with nitrogen atoms from the pyrazoles to form a stable molecule. Dimethylformamide is used as a solvent for this reaction. The synthesis of ethyl 3-aminopyrazole-4-carboxylate starts with acetylation, which converts the carboxylic acid group into an acetic acid group. The acetic acid group reacts with ammonia and hydrogen cyanFormula:C6H9N3O2Purity:Min. 95%Color and Shape:PowderMolecular weight:155.16 g/molPrucalopride Impurity 39
