title: Candida proteases and their inhibition: prospects for antifungal therapy.
abstract: The rationale for inhibition of the secreted acid proteases (SAP) of Candida fungal species as a novel antifungal strategy is outlined. Enzyme structure-activity relationship data regarding the inhibitor A-70450 are described along with results from in vivo antifungal assays. Developments from protein X-ray crystallographic studies, SAP knock-out genetic studies, and the importance of these new results for drug discovery are reviewed. Finally, inhibition of the Candida SAP enzymes with HIV protease inhibitors and a proposed role in candidiasis of AIDS patients is discussed.
