Area of Science:

  • Medicinal Chemistry
  • Microbiology
  • Virology

Background:

  • Acylcarnitine analogues represent a class of compounds with potential therapeutic applications.
  • Existing agents for topical microbicidal applications often face challenges with efficacy or resistance.
  • There is a need for novel compounds with broad-spectrum antimicrobial and antiviral activities.

Purpose of the Study:

  • To synthesize and evaluate a series of acylcarnitine analogues, designated as Z-n, for their in vitro biological activities.
  • To investigate the structure-activity relationship, specifically the effect of alkyl chain length on compound efficacy.
  • To identify lead compounds for potential development as topical microbicides.

Main Methods:

  • Multi-gram synthesis of acylcarnitine analogues (+)-6-Carboxylatomethyl-2-alkyl-4,4-dimethylmorpholinium (Z-n).

  • In vitro evaluation of inhibition against Candida albicans growth.

    • Main Results:

    • Synthesized acylcarnitine analogues (Z-n) exhibited significant in vitro spermicidal, anti-HIV, and antifungal activities.
    • A clear trend of improved activity was observed with increasing length of the alkyl chain (n).
    • Compound Z-15 demonstrated notable efficacy, positioning it as a strong candidate for further development.

    Conclusions:

    • Acylcarnitine analogues, particularly those with longer alkyl chains, possess promising broad-spectrum microbicidal properties.
    • Compound Z-15 is a viable candidate for further investigation as a topical microbicidal spermicide.
    • These findings support the potential of acylcarnitine analogues in developing new strategies against sexually transmitted infections and fungal infections.
