Abstract
The opportunistic fungus Candida krusei is the causative agent of nosocomial infections characterized by high mortality and development of resistance to drugs of the azole class. Therefore, develjoment of non-azole antifungal agents against resistant fungal strains is extremly important. Lanosterol 14-alpha demethylase (CYP51) is a well-known antifungal target. The optical SPR biosensor is a universal tool for screening studies in search of new drug prototypes. This paper presents the methodological aspects of high-hroughput SPR based screening of a library of low molecular weight compounds of natural origin for their interaction with C. krusei CYP51. It has been shown that when performing high-throughput screening, a researcher should pay special attention to the degree of a sensorgram curvature in the association phase. The described approaches to the analysis of high throughput screening data can be useful for researchers working with SPR biosensors from various manufacturers.
