Pathway Description
Raltitrexed Action Pathway
Homo sapiens
Drug Action Pathway
Raltitrexed is a folate analog that is used in the treatment of colorectal cancer, that is an inhibitor of thymidylate synthase. Inhibiting thymidylate synthase stops the proliferation of cancer cells, as it stops the production and formation of purines and pyrimidines needed for DNA replication. Once transported into the cells through a reduced folate carrier it is polyglutamated by folylpolyglutamate synthetase to further enhance the inhibitory action. There are some side effects that may occur such as pale skin, trouble breathing, bleeding, bruising, fatigue, chest pains, chills, cough, fever and issues with gastrointestinal issues.
