What it is Filled

A class of natural phenolic compounds based on a stilbene skeleton of two aromatic rings joined by an ethene bridge, including resveratrol, pterostilbene, piceatannol and plant stilbenoids such as pawhuskins, produced by plants as defence compounds; stilbenoids are studied for biological activities, used in some dyes, and are the subject of health claims requiring careful evaluation.

Why it exists Filled

Let an agent explain stilbenoids, their structure, sources and biological activities, and evaluate health claims about compounds such as resveratrol with evidence.

Distinguishing features Filled

  • Stilbene skeleton
  • Plant defence compounds
  • Phenolic
  • Bioactivity claims

What robots and AI may and may not do Filled

Must not

  • Claim that a stilbenoid supplement prevents or cures disease without approved evidence.
  • Recommend doses of supplements to individuals.
  • Ignore interactions of supplements with medicines when discussing them.
  • Present animal or cell studies as proof of effects in humans.

Only with a human decision

  • Any advice to a patient to take or stop a supplement.

May

  • Explain stilbenoid chemistry, sources and research findings with citations.
  • State clearly the difference between laboratory findings and proven effects in people.

Moral aspects Filled

  • Supplements are sold on overstated claims that can delay real treatment.
  • People on medicines can be harmed by interactions.

Who is affected

  • Consumers of supplements
  • Patients on medicines
  • Researchers

Owners Filled

Steward

Nobody: a class of natural compounds; makers of supplements answer for their products.

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.stilbenoid
  • Wikidata: Q526360 (https://www.wikidata.org/wiki/Q526360)

Direct properties required Filled

  • Melting temperature: degrees Celsius - Measure the identified compound by thermal analysis or a melting point method because different stilbenoids and solid forms have different values.
  • Mass solubility: grams per litre - Measure the equilibrium dissolved concentration of the identified compound in a specified solvent at a stated temperature and pH.
  • Molar mass: grams per mole - Calculate the value from the molecular formula of the identified stilbenoid because the class has no single molar mass.

Recognition required Filled

  • Stilbene backbone
  • Phenolic plant compounds
  • Flavonoids have a different ring system
  • Not visible; compounds in plants, sometimes as crystalline solids.

Capabilities and actions required Filled

  • explain stilbenoid structure and biosynthesis
  • identify sources and examples
  • summarise biological activities with attribution
  • evaluate health claims

Hazards and failure modes required Filled

  • Unsupported health claims
  • Confusing stilbenoids with flavonoids
  • Supplement quality problems

Standards and interfaces required Filled

  • Supplement and health claim regulations
  • Chemical safety regulations

Context of use required Filled

  • Natural products chemistry, plant science and nutrition.
  • resveratrol and its derivatives
  • pterostilbene and piceatannol
  • oligomeric stilbenoids
  • prenylated stilbenoids such as pawhuskins
  • stilbene dyes (synthetic relatives)

  2. Wikipedia: Stilbenoid - general description of the item

Open questions

  • Should resveratrol be a separate entry?
  • How should natural product databases be linked?
