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:Tenofovir isoproxil monoester is a prodrug of Tenofovir, which is an antiviral drug. Tenofovir prevents the growth of HIV by interfering with the synthesis of viral DNA. The process development stage involves converting Tenofovir to its disoproxil monoester form, which has been shown to have greater antiviral activity than Tenofovir alone. This conversion process involves condensing one molecule of fumarate with two molecules of tenofovir, forming tenofovir disoproxil fumarate (TFD). TFD can be converted back to Tenofovir using hydrolysis and hydrogenation. Impurities in TFD include isopropyl tenofovir and unidentified impurities that are not present in the parent drug, tenofovir. Tenofovir Disoproxil Fumarate was also shown to be more potent than TFD and is undergoing clinical trials forFormula:C14H22N5O7PPurity:Min. 97 Area-%Color and Shape:White/Off-White SolidMolecular weight:403.33 g/mol4-Amino-2-(methylthio)pyrimidine-5-carboxylic acid
