NCIt definition : An orally bioavailable, small molecule, non-polyglutamatable, antifolate quinazoline
derivative thymidine synthetase inhibitor with potential antineoplastic activity.
Plevitrexed is transported into the cell via the physiological reduced folate carrier
(RFC) system. Intracellularly, this agent selectively binds to the folate binding
site of thymidylate synthase and inhibits thymidine synthesis, which may result in
DNA synthesis inhibition and apoptosis.;
