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 disoproxil related compound B is a peptidyl prodrug that is metabolized by esterases to tenofovir. It has been shown to be an effective agent against Mycobacterium tuberculosis and other bacterial species. Tenofovir disoproxil related compound B was also found to inhibit protein synthesis in Mycobacterium avium and Mycobacterium smegmatis, but not in Escherichia coli. This drug binds to the ribosome's 30S subunit, which blocks the binding of aminoacyl-tRNA and prevents the formation of peptide bonds. The mechanism of action for this drug is similar to that of the antibiotic erythromycin.Formula:C8H9N5Purity:Min. 98 Area-%Molecular weight:175.19 g/molPalonosetron USP Related Compound E
