  <description>Pemetrexed is an organic compound with the chemical formula C20H21N5O6 and an average molecular weight of 427.41 g/mol. Pemetrexed belongs to the amino acids, peptides, and analogues, a subclass of carboxylic acids and derivatives within the organic compounds.

This compound is found in or released from two recorded sources: antennas within electrical and electronic equipment, and antineoplastic agents within healthcare, pharmaceuticals, and veterinary products. Recorded routes of exposure include intraventricular and intravenous administration. Pemetrexed acts on five recorded protein targets. It functions as an inhibitor of thymidylate synthase (TYMS), dihydrofolate reductase (DHFR), the bifunctional purine biosynthesis protein ATIC, and the trifunctional purine biosynthetic protein adenosine-3 (GART), as well as one other protein.</description>
