DHFR Inhibitor

What DHFR Inhibitor Means

A DHFR inhibitor, short for dihydrofolate reductase inhibitor, is a type of medicine that blocks an enzyme called dihydrofolate reductase. This enzyme helps cells use folate, a vitamin-like nutrient needed to make DNA. Since cancer cells divide quickly, they need a lot of folate to grow and multiply. By blocking this enzyme, DHFR inhibitors can slow or stop cancer cells from making DNA, which may help stop their growth or kill them.

Why DHFR Inhibitors Matter in Cancer Care

Because cancer cells rely on folate to divide, DHFR inhibitors can be useful in cancer treatment. Some drugs in this group, such as methotrexate and its related medicines, are used to treat certain cancers. These drugs are part of a larger family called antifolates. By interfering with folate use, they aim to slow down or stop cancer growth. However, not all DHFR inhibitors are used for cancer; some are used for infections or other conditions.
