    Area of Science:

    • Organic Chemistry
    • Microbiology
    • Medicinal Chemistry

    Context:

    • Bile acids, such as cholic acid, are natural steroids with diverse biological roles.
    • The emergence of antimicrobial resistance necessitates the development of novel therapeutic agents.
    • Amino acid conjugation is a strategy to modify the properties of existing molecules.

    Purpose:

    • To synthesize and evaluate the in vitro antimicrobial activity of cholic acid and dehydrocholic acid derivatives.
    • To investigate the structure-activity relationship between bile acid-amino acid conjugates and their antimicrobial efficacy.

    Summary:

    • Condensation products of cholic acid and dehydrocholic acid with various L-amino acids were synthesized.
    • Antimicrobial activity was assessed in vitro.
    • Derivatives formed with basic L-amino acids exhibited significant antimicrobial effects, with L-arginine conjugates showing the most pronounced activity.

    Impact:

    • Identifies specific bile acid-amino acid derivatives with potent in vitro antimicrobial properties.
    • Suggests a promising avenue for developing new antimicrobial drugs based on steroid scaffolds.
    • Provides a foundation for further research into the mechanism of action and in vivo efficacy of these compounds.
