Encyclopedia

From Wikipedia, the free encyclopedia

A dihydrofolate reductase inhibitor is a molecule that inhibits the function of dihydrofolate reductase, and is a type of antifolate.

Since folate is needed by rapidly dividing cells to make thymine, this effect may be used to therapeutic advantage. For example, methotrexate is used as cancer chemotherapy because it can prevent neoplastic cells from dividing.[1][2] Bacteria also need DHFR to grow and multiply and hence inhibitors selective for bacterial vs. host DHFR have found application as antibacterial agents.[3]

Tetrahydrofolate synthesis pathway

A variety of drugs act as inhibitors of dihydrofolate reductase:
