Abstract | The rise of antifungal resistance and limited treatment options highlight the urgent need for new drug classes. Candida auris is a serious global health threat with few effective therapies. In this study, novel azole-based compounds were developed by modifying the azole core with cyclic heteroaliphatic linkers connecting aromatic and heteroaromatic rings. Several compounds showed potent activity against C. auris, including azole-resistant strains, with MICs ranging from 0.016 to 4 µg/mL. The compounds also demonstrated strong activity against C. albicans, Nakaseomyces glabratus, C. tropicalis, and C. parapsilosis, with MICs mostly below 1 µg/mL. Compounds 7, 18, and 21 were more potent than fluconazole. Compound 7 inhibited CYP51, eradicated C. auris biofilms, and showed better intracellular accumulation than fluconazole. In vivo studies in Galleria mellonella and Drosophila melanogaster confirmed efficacy at 5 mg/kg and no toxicity up to 50 mg/kg, supporting further development of this scaffold against multidrug-resistant C. auris infections. |
