Inhibits thymidylate synthase (TS), 421 dihydrofolate reductase (DHFR), and glycinamide ribonucleotide formyltransferase (GARFT). It has a role as an antimetabolite, an antineoplastic agent, an EC 1.5.1.3 (dihydrofolate reductase) inhibitor, an EC 2.1.1.45 (thymidylate synthase) inhibitor and an EC 2.1.2.2 (phosphoribosylglycinamide formyltransferase) inhibitor. It is an organic sodium salt and a hydrate. It contains a pemetrexed disodium."}]
