Unlike bacterial cells, fungal cells are eukaryotes, sharing many biological similarities with human cells. This close phylogenetic relationship presents a significant challenge in antifungal drug development: finding targets that are essential for fungal survival but absent or significantly different in human hosts, thereby minimizing host toxicity. Our efforts in elucidating mechanisms of action (MoA) for novel antifungal candidates focus on exploiting these critical fungal-specific pathways and structures:
Genomic and Proteomic Revolution
The increasing availability of complete fungal pathogen genomes enables comprehensive "subtractive genomics" approaches to identify essential fungal genes and proteins that are absent in humans. Proteomics further elucidates protein expression patterns and post-translational modifications under various stress conditions, including drug exposure.
Gene Editing
Precise gene editing tools allow for high-throughput functional genomics screens in fungal pathogens, enabling rapid validation of gene essentiality and identification of novel drug targets. This technology facilitates the creation of resistant strains to study MoA and resistance mechanisms.
AI and Machine Learning in Target Prediction
AI algorithms are now employed to analyze vast biological datasets, predict potential drug-target interactions, and even design novel molecules with antifungal activity. This computational power significantly accelerates the lead discovery phase.
Phenotypic Screening and Target Deconvolution
Rather than starting with a known target, phenotypic screens identify compounds that inhibit fungal growth, followed by sophisticated target deconvolution strategies (e.g., chemical proteomics, transcriptomics) to pinpoint the specific cellular pathways or proteins affected.
New Delivery Systems
Nanotechnology-based drug delivery systems are being explored to enhance antifungal drug delivery, improve targeting, and reduce toxicity, even for existing drugs. This includes liposomal formulations and nanoparticles.
Repurposing and Combination Therapies
Identifying existing drugs with unsuspected antifungal activity or developing synergistic drug combinations that overcome resistance or enhance efficacy.

What is the biggest challenge in antifungal drug discovery?
A major challenge is the eukaryotic nature of fungi, which limits the number of fungal-specific targets to exploit without causing significant host toxicity. The rapid evolution of antifungal resistance also poses a continuous hurdle.
Can you develop custom assays for my specific fungal pathogen or target?
Yes, assay development is a core strength. We routinely develop and optimize bespoke biochemical, cell-based, and phenotypic assays tailored to your unique research needs and fungal species of interest.
