Bis-Pro-5FU (Compound 4) is a 5-FU precursor that confers oral bioavailability and increase the safety profile of 5-Fluorouracil (5-FU) chemotherapy regimens. 5-FU is an antineoplastic antimetabolite that is widely used for the research of colorectal and pancreatic cancer.

Tegafur (also known as Ftorafur) is a chemotherapeutic 5-FU prodrug used in the treatment of cancers; is a component of tegafur-uracil.

Flurocitabine is a fluorinated anlydride analog of cytosine arabinoside, partially hydrolysecl in vivo into two active antitumor substances (arabinosyl-tluorocytosine (ara-FC) and arabinosyl-fluorouracil (ara-FU)). Flurocitabine has antitumor activity during phase I studies in acute leukemia and solid tumors.

Gemcitabine elaidate (CP-4126) hydrochloride is lipophilic pro-drug of Gemcitabine. Gemcitabine elaidate hydrochloride is converted to Gemcitabine by esterases in order to be phosphorylated. Gemcitabine elaidate hydrochloride exhibits anti-tumor activity.

Fostroxacitabine bralpamide (MIV-818) is an orally active Troxacitabine-based nucleotide prodrug. Fostroxacitabine bralpamide has anticancer effects.

5'-O-DMT-rU is a modified nucleoside and can be used to synthesize RNA.

3'-Deoxyuridine-5'-triphosphate trisodium (3'-dUTP trisodium) is a nucleotide analogue that inhibits DNA-dependent RNA polymerases I and II. 3'-Deoxyuridine-5'-triphosphate trisodium strongly and competitively inhibits the incorporations of UTP into RNA with a Ki value of 2.0 μM.

Adenosine 5′-monophosphoramidate sodium is an adenosine derivative and can be used as an intermediate for nucleotide synthesis. Adenosine 5′-monophosphoramidate has a significant effect on the accumulation of cyclic AMP.

6-Azathymine, a 6-nitrogen analog of thymine, is a potent D-3-aminoisobutyrate-pyruvate aminotransferase inhibitor. 6-Azathymine inhibits the biosynthesis of DNA, and has antibacterial and antiviral activities.

3'-Deoxyuridine-5'-triphosphate (3'-dUTP) is a nucleotide analogue that inhibits DNA-dependent RNA polymerases I and II. 3'-Deoxyuridine-5'-triphosphate strongly and competitively inhibits the incorporations of UTP into RNA with a Ki value of 2.0 μM.

Adenosine Dialdehyde, a purine nucleoside analogue, is an irreversible inhibitor of S-adenosylhomocysteine hydrolase (SAH) (IC50=40 nM). Adenosine Dialdehyde exhibits potent anti-tumor activity in vivo and can be used for the cancer research.

Peldesine (BCX 34) dihydrochloride is a potent, competitive, reversible and orally active purine nucleoside phosphorylase (PNP) with IC50s of 36 nM, 5 nM, and 32 nM for human, rat, and mouse red blood cell (RBC) PNP, respectively. Peldesine dihydrochloride is also a T-cell proliferation with an IC50 of 800 nM. Peldesine dihydrochloride has the potential for cutaneous T-cell lymphoma, psoriasis and HIV infection treatment.

(Rac)-Plevitrexed ((Rac)-ZD 9331; (Rac)-BGC9331) is a racemate of Plevitrexed. Plevitrexed is an orally active and potent thymidylate synthase (TS) inhibitor.

Plevitrexed (ZD 9331; BGC 9331) is an orally active and potent thymidylate synthase (TS) inhibitor with a Ki of 0.44 nM. Plevitrexed is taken up via the α-folate receptor as well as the reduced folate carrier. Plevitrexed is used for gastric cancer in clinical.

Sapacitabine is an orally bioavailable pyrimidine analogue prodrug with potential antineoplastic activity.

Gemcitabine(Gemzar) belongs to the group of medicines called antimetabolites.

Elacytarabine (CP-4055, CP4055) is a fatty acid derivative of cytarabine with potential antineoplastic activity.

A naturally occurring nucleoside analog that possesses antitumor activity, also is a potent and efficacious readthrough agent.

5-Fluorouracil is a potent antitumor agent that affects pyrimidine synthesis by inhibiting thymidylate synthetase thus depleting intracellular dTTP pools.
