Glucosinolates and Cancer Prevention Effects

  • Glucosinolates: Compounds found in plants that have anti-cancer effects.

  • Methyl Jasmonate: A plant hormone naturally produced during pest or pathogen infection, first isolated from jasmine flowers. It signals plants to produce metabolic products mimicking pest damage.

Application of Methyl Jasmonate

  • Treatment of plants with methyl jasmonate increases glucosinolates:

    • After applying to broccoli, harvested 4 days later:

      • Gloconas: Increase of 85%.

      • Neo Glocovracy: Increase of 400%.

  • Experiment conducted repeatedly over 2 years with 5 broccoli varieties; considering environmental changes necessitates repeated trials.

Enzyme Activity and Cancer Prevention

  • Queno Reductase: An enzyme that breaks down carcinogenic substances.

  • Increased glucosinolates lead to heightened hydrolysis products, enhancing cancer prevention effects.

Historical Research and Discoveries

  • Research on glucosinolates initially did not focus on cancer prevention; discovered during studies on goitrogenic phenomena.

  • Progoitrin: Inhibits iodine absorption in the thyroid.

Canola and Glucosinolates

  • Canola oil: Low-acid oil used in animal feed.

  • Alucic Acid, Glucosylate: Inhibits weight gain.

  • Successful cases of canola varieties with lowered glucosinolates explained.

Glucosinolates Biosynthesis

  • Summary of biosynthetic processes:

    • Originates from amino acids.

    • Side chain theories and structure formation.

    • Functional group modification.

    • Generation of bioactive substances through degradation.

Allelopathy and Antagonistic Effects

  • Allelopathy: One plant inhibits the growth of another.

  • Allelochemicals: Substances produced by such plants.

  • Potential for herbicide development.

  • Garling Mustard: Contains strong glucosinolates, hindering growth of surrounding plants.

Research and Experiments

  • Black walnut and sorghum: Effective in studies on antagonistic effects.

  • Experiment Results:

    • Holth radish extracts inhibited lettuce germination.

    • AITC: Highly reactive.

Conclusion

  • Importance and potential of studies on antagonistic effects:

    • Applicability in agriculture and food industry.

    • Understanding the diverse functionalities of glucosinolates aids in promoting health.
