Abstract

Insights

A novel peptide, KW-23, shows potent antimicrobial activity against Candida albicans strains. Combined with fluconazole, it offers a promising, low-toxicity therapeutic option for candidiasis.

Area of Science:

  • Microbiology
  • Pharmacology
  • Biochemistry

Background:

  • * *Candida albicans* infections pose significant treatment challenges due to drug resistance and toxicity.
  • * Effective antifungal therapies are scarce, necessitating novel antimicrobial agents.
  • * Invasive candidiasis can be life-threatening, highlighting the need for new treatments.

Purpose of the Study:

  • * To evaluate the efficacy of the KW-23 peptide against *Candida albicans*.
  • * To assess the synergistic effect of KW-23 in combination with fluconazole.
  • * To determine the toxicity profile of the KW-23 peptide.

Main Methods:

  • * Design and synthesis of a conjugated ultrashort antimicrobial peptide (KW-23).
  • * Antimicrobial susceptibility testing using standard and checkerboard assays against *C. albicans*.
  • * Hemolytic assays to evaluate peptide toxicity on human erythrocytes.

Main Results:

  • * KW-23 demonstrated potent activity against standard and resistant *C. albicans* strains.
  • * Significant synergistic antimicrobial activity was observed when KW-23 was combined with fluconazole against the standard strain.
  • * Additive effects were noted for the combination against resistant strains, with negligible toxicity to human erythrocytes.

Conclusions:

  • * KW-23 exhibits promising anticandidal properties.
  • * The combination of KW-23 and fluconazole represents a potential therapeutic strategy for candidiasis.
  • * Further development of KW-23 could address unmet needs in antifungal treatment.
