The DNA hypomethylating agents (HMAs) 5-azacitidine and decitabine are the backbone of disease modifying therapy in myelodysplastic syndromes (MDS). We show that pyrimethamine, an FDA-approved antifolate, induces apoptosis across leukemic models, synergizes with venetoclax, and restores sensitivity in HMA- and venetoclax-resistant leukemia. Pyrimethamine promotes differentiation of stem and progenitor cells in primary MDS samples and in combination with venetoclax directly inhibits pyrimidine synthesis, revealing a clinically actionable strategy to overcome a key mechanism of therapeutic resistance.
