pemetrexed disodium![Patient Information Patient Information](https://webarchive.library.unt.edu/eot2008/20081006171659im_/http://www.cancer.gov/images/btn-patient-info.gif) The disodium salt of a synthetic pyrimidine-based antifolate. Pemetrexed binds to and inhibits the enzyme thymidylate synthase (TS) which catalyses the methylation of 2'-deoxyuridine-5'-monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP), an essential precursor in DNA synthesis. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
