• Opium poppy is the sole commercial source of noscapine.

Purpose of the Study:

• To provide a historical overview of noscapine discovery and early research.
• To detail recent breakthroughs in elucidating the noscapine biosynthetic pathway.
• To discuss pharmacological properties and potential pharmaceutical applications.

Main Methods:

• Review of historical data and scientific literature.
• Integration of findings from molecular genetics, functional genomics, and metabolic biochemistry.
• Analysis of pharmacological data for noscapine and its derivatives.

Main Results:

• The biosynthesis pathway of noscapine has been almost completely established.
• Significant progress has been made in understanding the formation of noscapine in opium poppy.
• Noscapine and its derivatives exhibit promising pharmacological activities for pharmaceutical applications.

Conclusions:

• The elucidation of noscapine biosynthesis is a major scientific achievement.
• Noscapine holds significant potential as an anticancer therapeutic.
• Future production may involve metabolic engineering and synthetic biology in plants and microbes.
