Pemetrexed (also known as pemetrexed disodium) is a novel antifolate antimetabolite targeting multiple enzymes involved in both pyrimidine and purine synthesis. Pemetrexed is an analog of the classic antifolate GARFYT inhibitor lometroxol with a similar chemical structure, where the pyrazine ring in the pterine portion of folic acid and the benzylic nitrogen in the bridge portion of folic acid are replaced by a pyrrole ring and a methylene group respectively. Pemetrexed potently inhibits TS, DHFR, and GARFT as well as AICARFT but with a lesser potency and exhibits autitumor activity in a broad range of tumors, including non-small cell lung carcinoma, malignant mesothelioma, and carcinomas of the breast, colorectum, uterine cervix, head and neck, and bladder.
