92-61-5 | Scopoletin

Chemical type

• Coumarin-type phenolic (coumarins/coumestans)

^[1]

• Coumarin

^[2]

Key properties

• Synthesized from feruloyl-CoA / phenylpropanoid pathway
• Exhibits antimicrobial activity
• Induced by pathogen and abiotic stresses
• Regulated via SA/JA signaling and F6′H transcriptional control

^[1]

• Antioxidant; phytoalexin; inhibitory effects on fungi (e.g., Phakopsora pachyrhizi, Fusarium solani, Fusarium oxysporum) and viruses (e.g., tobacco mosaic virus); accumulates in response to biotic stresses like pathogen attacks; produced via hydrolysis of scopolin by β-glucosidases.

^[2]

• Accumulates in roots for defense and microbiome interactions in Arabidopsis and legumes
• Antioxidant and antimicrobial roles

^[1]

• Plant defense against pests, diseases, and environmental stresses; anti-inflammatory and analgesic effects in traditional Chinese medicine (e.g., in Angelica dahurica formulations like Du Liang soft capsule); potential role in immunomodulation and toxicity to herbivores.

^[2]

Classification by use

• Phytoalexins used in microbial resistance and stress tolerance
• Phenolic compounds for root defense

^[1]

• Chemicals involved in plant defense mechanisms
