Curator's Comment: Description was created based on several sources, including http://www.cancer.gov/publications/dictionaries/cancer-drug?cdrid=42223

The dihydrochloride salt of nolatrexed, a water-soluble lipophilic quinazoline folate analog with antineoplastic activity. Nolatrexed occupies the folate binding site of thymidylate synthase, resulting in inhibition of thymidylate synthase activity and thymine nucleotide synthesis with subsequent inhibition of DNA replication, DNA damage, S-phase cell cycle arrest, and caspase-dependent apoptosis. This agent also exhibits radiosensitizing activity. Orphan designation of nolatrexed was granted in the Unites States of America for treatment of hepatocellular carcinoma.

Sample Use Guides

In Vivo Use Guide

Nolatrexed can be safely administered as an oral preparation at a dose of 800 mg/m2/day for 5 days.

Route of Administration: Oral

In Vitro Use Guide

In HT29 cells, exposure to nolatrexed (5 uM) for 24 h induced S-phase cell cycle arrest. In HCT116 cells, exposure to nolatrexed (5 lM) for 24 h also induced S-phase arrest with the cell population significantly increasing during this phase from 24% to 40%.
