Potential Antifungal Targets Based on Glucose Metabolism Pathways of Candida albicans

Area of Science:

• Medical Mycology
• Biochemistry
• Drug Discovery

Background:

• Fungal infections, particularly from Candida albicans, are a growing health concern, causing significant mortality in hospitalized patients.
• Current antifungal drugs have limitations including toxicity, high cost, and limited efficacy, necessitating the development of novel therapeutic agents.
• Candida albicans virulence is linked to nutrient metabolism, with glucose being a critical nutrient source.

Purpose of the Study:

• To review glucose metabolism pathways in Candida albicans.
• To identify potential antifungal targets within these pathways.
• To summarize compounds exhibiting antifungal activity by inhibiting key enzymes in glucose metabolism.

Main Methods:

• Literature review of glucose metabolism in Candida albicans.
• Analysis of enzymes within glucose metabolic pathways as potential drug targets.
• Compilation of existing studies on antifungal compounds targeting these enzymes.

Main Results:

• Several enzymes in Candida albicans glucose metabolism pathways are validated antifungal targets.
• Inhibitors of alpha-glucosidase, acid trehalase, trehalose-6-phosphate synthase, fructose bisphosphate aldolases, and glucosamine-6-phosphate synthase demonstrate antifungal activity.
• Targeting glucose metabolism offers a promising avenue for new antifungal drug development.

Conclusions:

• Glucose metabolism pathways in Candida albicans present numerous targets for novel antifungal drug development.
• Inhibiting specific enzymes involved in glucose utilization can effectively combat Candida albicans infections.
• This review provides a foundation for future research into new antifungal agents with unique mechanisms of action.
