raltitrexed
A quinazoline folate analogue with antineoplastic activity. After transport into cells via the reduced folate carrier, raltitrexed undergoes intracellular polyglutamation and blocks the folate-binding site of thymidylate synthase, thereby inhibiting tetrahydrofolate activity and DNA replication and repair and resulting in cytotoxicity. Check for active clinical trials using this agent. (NCI Thesaurus)
