DescriptionThymidine is a naturally occurring deoxyribonucleoside that is a crucial component of the DNA salvage pathway and a building block for DNA synthesis.[A274683] While it lacks significant anti-tumor activity on its own,[A274688] it has been extensively investigated for nearly a decade as a biochemical modulator to enhance the efficacy and reduce the toxicity of established anti-metabolite chemotherapeutic agents, such as 5-Fluorouracil (FU), Methotrexate (MTX), and Cytosine arabinoside (ara-C).[A274683, A274688] As of now, its primary role is in research and as a sensitizer or modulator in experimental chemotherapy regimens, rather than a standalone, approved therapeutic agent.[A274683, A274688, A274703]
