What Are Mutagenic Drugs and Why Do They Matter?

Mutagenic drugs induce DNA mutations either intentionally—as in mutagenesis research—or inadvertently—as in certain chemotherapeutics aiming to trigger mutations in cancer cells. The dual nature demands a nuanced understanding of their market and patent environment:

Definition	Purpose	Examples	Regulatory Considerations
Chemical compounds or biologics that induce genetic mutations	Research tools, cancer therapies, or experimental agents	Alkylating agents (e.g., cyclophosphamide), Nucleoside analogs (e.g., 5-Azacytidine)	Stringent safety, approval by agencies (FDA, EMA)
