Mechanism of Action Compared With Other Alkylating Agents

Author(s)Joshua K. Sabari, MD

Joshua K. Sabari, MD, describes the mechanism of action of lurbinectedin as a synthetic alkaloid that binds to guanine residues in the minor groove of DNA, forming adducts that disrupt DNA repair mechanisms and promote apoptosis in cancer cells, noting that its action contrasts with traditional alkylating agents by specifically interfering with DNA-protein interactions and transcription processes.
