Area of Science:

  • Toxicology
  • Medicinal Chemistry
  • Molecular Biology

Background:

  • Mycotoxins, secondary metabolites from fungi, pose significant risks to human and animal health.
  • Understanding the link between mycotoxin chemical structures and their biological activities is crucial for risk assessment and management.

Purpose of the Study:

  • To review the structure-activity relationships (SAR) of various mycotoxin chemical families.
  • To highlight key chemical and physicochemical factors governing mycotoxin bioactivity.
  • To correlate structural features with diverse biological effects.

Main Methods:

  • Literature review of scientific publications on mycotoxins.
  • Analysis of chemical structures across different mycotoxin classes.
  • Correlation of structural data with reported biological effects at molecular, cellular, and supracellular levels.

Main Results:

  • Identified major chemical and physicochemical determinants of mycotoxin bioactivity.
  • Discussed SAR for diverse mycotoxin families including lactones, aflatoxins, trichothecenes, and others.
  • Linked structural characteristics to a range of biological effects such as toxicity, mutagenicity, and carcinogenicity.

Conclusions:

  • Mycotoxin biological effects are intrinsically linked to their molecular structures.
  • SAR analysis provides a framework for understanding mycotoxin toxicity and developing mitigation strategies.
  • Further research into SAR can aid in the identification of novel bioactive compounds and toxicological mechanisms.
