Mechanism:

Pemetrexed (Alimta®) works by disrupting folate-dependent metabolic processes essential for the rapid growth of tumors. The inhibition of the enzyme thymidylate synthase (TS) leads to inhibition of DNA synthesis, which eventually results in depletion of reduced folates and essential carriers of celular metabolism.1
