N6,N6-Dimethyladenosine is find in mycobacterium bovis Bacille Calmette-Guérin tRNA.

1-Methylinosine (N1-Methylinosine) is a modified nucleotide found at position 37 in tRNA 3' to the anticodon of eukaryotic tRNA and has a role as a metabolite.

5-Bromo-2’,3’,5’-tri-O-acetyluridine is a purine nucleoside analog that is being explored to improve Alzheimer’s and Parkinson’s diseases.

Doxifluridine (AMC 0101) is a fluoropyrimidine derivative and oral prodrug of the antineoplastic agent 5-fluorouracil (5-FU) with antitumor activity. Doxifluridine, designed to circumvent the rapid degradation of 5-FU by dihydropyrimidine dehydrogenase in the gut wall, is converted into 5-FU in the presence of pyrimidine nucleoside phosphorylase. 5-FU interferes with DNA synthesis and subsequent cell division by reducing normal thymidine production and interferes with RNA transcription by competing with uridine triphosphate for incorporation into the RNA strand.

Sapacitabine (CS682) is an orally available nucleoside analog precursor compound with potential anti-tumor activity for the study of acute myeloid leukemia.
