Pemetrexed（Cat No.:I001434）is a multi-targeted antifolate chemotherapeutic agent used primarily in the treatment of malignant pleural mesothelioma and non-small cell lung cancer (NSCLC). It works by inhibiting several key enzymes involved in folate-dependent processes, including thymidylate synthase, dihydrofolate reductase, and glycinamide ribonucleotide formyltransferase. This inhibition disrupts DNA synthesis and cell division, particularly in rapidly dividing cancer cells. Pemetrexed is a cornerstone in oncology research for exploring novel cancer treatments and combination therapies, making it a vital component in clinical and pharmaceutical studies aimed at improving patient outcomes.
