Mechanism of action

FEC combines fluorouracil (a thymidylate synthase inhibitor), epirubicin (a topoisomerase II inhibitor and DNA intercalator), and cyclophosphamide (an alkylating agent). Together, these agents attack cancer cells through multiple mechanisms: fluorouracil disrupts nucleotide synthesis, epirubicin intercalates into DNA and prevents replication, and cyclophosphamide cross-links DNA strands. The combination is designed to provide synergistic cytotoxic effects against rapidly dividing cancer cells.
