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:Methotrexate-5-monomethyl ester is an analytical standard that is synthesized synthetically. The synthetic route used to produce the compound has been optimized for high purity, making this product suitable for use as a drug product or impurity standard. The structure of methotrexate-5-monomethyl ester was confirmed by 1H and 13C NMR spectroscopy and mass spectrometry. Methotrexate-5-monomethyl ester is an impurity found in the synthesis of methotrexate and is a metabolite of methotrexate. It has been shown to inhibit DNA synthesis and protein synthesis in animal cells, which may be due to its ability to inhibit transcription factors such as NFATc1, NFkB, STAT3, STAT5A and STAT5B.Formula:C21H24N8O5Purity:Min. 95%Molecular weight:468.47 g/molSumatriptan Succinate
