A small molecule, inhibitor of a protein–protein interaction between the transcription factor Pdr1 and the Med15 subunit of Mediator in the fungal pathogen Candida glabrata, is identified and characterized here; the compound iKIX1 inhibits Pdr1-mediated gene activation and resensitizes drug-resistant C. glabrata to azole antifungals in vitro and in animal models of disseminated and urinary tract infection.
