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.

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.

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

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-Azacytidine (Ladakamycin) is a cytidine nucleoside analog, a DNA methylation inhibitor with specificity. 5-Azacytidine regulates gene expression by decreasing the level of DNA methylation. 5-Azacytidine induces autophagy and has antitumor activity.

6-Mercaptopurine (6-MP) is an antimetabolite antineoplastic agent with immunosuppressant properties. It interferes with nucleic acid synthesis by inhibiting purine metabolism and is used, usually in combination with other drugs, in the treatment of or in remission maintenance programs for leukemia.
