Abstract

Multi-drug resistance is becoming an increasingly severe clinical challenge not only among pathogenic bacteria but among fungal pathogens as well. Drug design is inherently more challenging for the eukaryotic fungi due to their closer evolutionary similarity to humans. The recent rapid expansion in invasive infections throughout the world by Candida auris is of particular concern due to a substantial mortality rate, comparatively facile transmission, and an increasing level of resistance to all three of the major classes of anti-fungal drugs. One promising avenue for the development of an alternative class of anti-fungal agents currently under investigation is for drugs against the FK506-binding protein FKBP12 which, when bound to that drug, inhibits the fungal calcineurin signaling pathway with a resultant diminution in virulence. The specific challenge to this approach is that the homologous human calcineurin pathway functions in controlling the tissue immunity response, so that drug selectivity for the fungal pathway must be designed. To facilitate such efforts, we report the nearly complete backbone and sidechain resonances for the FKBP12 proteins of both Candida auris and clinically significant Candida glabrata fungi.
