Folate Antagonists

Folate Antagonists

Folate Antagonists. Enzymes requiring folate-derived cofactors are essential for the synthesis of purines and pyrimidines (precursors of RNA and DNA) and other compounds necessary for cellular growth and replication. In the absence of folate, cells cannot grow or divide.
