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.

Trifluridine (NSC-75520) is a fluorinated thymidine analog with potential antineoplastic activity. Trifluridine is incorporated into DNA and inhibits thymidylate synthase, resulting in inhibition of DNA synthesis, inhibition of protein synthesis, and apoptosis. This agent also exhibits antiviral activity.

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.

It has some antineoplastic properties and has broad spectrum activity against DNA viruses in cell cultures and significant antiviral activity against infections caused by a variety of viruses such as the herpes viruses, the VACCINIA VIRUS and varicella zoster virus.

Dacarbazine (DTIC-Dome) is an antineoplastic agent. It has significant activity against melanomas.

2'-O-Methylcytidine is a nucleoside derivative and an inhibitor of hepatitis C virus (HCV) non-structural protein 5B (NS5B; IC50= 3.8 μM).1It inhibits HCV replication in a replicon assay (IC50= 21.2 μM). 1.Migliaccio, G., Tomassini, J.E., Carroll, S.S., et al.Characterization of resistance to non-obligate chain-terminating ribonucleoside analogs that inhibit hepatitis C virus replication in vitroJ.

Stavudine (BMY-27857), a nucleoside reverse transcriptase inhibitor analog of thymidine, has activity against HIV.

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.

L-Uridine is the enantiomer of D-uridine, a nucleoside that acts as a phosphate acceptor for nucleoside phosphotransferase, in the normal RNA component of a normal RNA isolated from Polyporaceae fungus Poria cocos (Schw.) L-Uridine has potential antiviral activity.

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.

Cytarabine (Ara-C) is a nucleoside analog, an inhibitor of DNA synthesis (IC50=16 nM). Cytarabine inhibits DNA polymerase and induces cell cycle arrest, autophagy, and apoptosis. Cytarabine has antitumor activity.

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.

Adenosine (D-Adenosine) is a natural product, a ribonucleoside consisting of adenine bound to ribose. Adenosine has vasodilatory, antiarrhythmic and analgesic effects.

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.

Capecitabine (Capecitibine) is a fluoropyrimidine carbamate belonging to the class of antineoplastic agents called antimetabolites. As a prodrug, capecitabine is selectively activated by tumor cells to its cytotoxic moiety, 5-fluorouracil (5-FU); subsequently, 5-FU is metabolized to two active metabolites, 5-fluoro-2-deoxyuridine monophosphate (FdUMP) and 5-fluorouridine triphosphate (FUTP) by both tumor cells and normal cells. FdUMP inhibits DNA synthesis and cell division by reducing normal thymidine production, while FUTP inhibits RNA and protein synthesis by competing with uridine triphosphate for incorporation into the RNA strand.
