Nolatrexed Dihydrochloride (CAS 152946-68-4) is 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. Its synergistic anticancer effect has reported.

Overview of Clinical Research

Nolatrexed Dihydrochloride is a Thymidylate synthase inhibitor developed by Agouron Pharmaceuticals. Nolatrexed or 5-fluorouracil in combination with cisplatin in patients with nasopharyngeal cancer was completed in 2015.
