Floxuridine (FUDR) is an antimetabolite, floxuridine inhibits thymidylate synthase, resulting in disruption of DNA synthesis and cytotoxicity.

Ganciclovir (2'-Nor-2'-deoxyguanosine) is an ACYCLOVIR analog that is a potent inhibitor of the Herpesvirus family including cytomegalovirus. Ganciclovir is used to treat complications from AIDS-associated cytomegalovirus infections.

Adenosine 5'-monophosphate disodium salt (Adenosine Phosphate Disodium) is a purine nucleotide involved in ATP metabolism and is used to study the effects of ATP on cells and organisms. Adenosine 5'-monophosphate disodium salt has been shown to have a variety of biochemical and physiological effects. It has been shown to increase cell metabolism, gene expression, and protein synthesis.

Cytidine (Cytosine-1-β-D-ribofuranoside) is a pyrimidine nucleoside comprised of a cytosine bound to ribose via a beta-N1-glycosidic bond. Cytidine is a precursor for uridine. Both cytidine and uridine are utilized in RNA synthesis.

Gemcitabine hydrochloride (LY 188011 hydrochloride) is a synthetic cytosine nucleoside derivative and an inhibitor of DNA synthesis. Gemcitabine has antitumor and antimetabolic activities. Gemcitabine induces autophagy and apoptosis.

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.

5-BrdU (Broxuridine) , a nucleoside analog, are used in the detection of proliferating cells and competes with thymidine for incorporation into DNA.

Orotic acid (Vitamin B13) is an intermediate product in pyrimidine metabolism.
