摘要

DNA topoisomerase I is a potential target for therapeutic antifungal agents predicted to have a fungicidal mode of action. This report describes four agents with varying degrees of selectivity for the fungal topoisomerase I compared to the human enzyme: 5-hydroxy-1H-indole-3-acetic acid (5-HIAA), quinizarin, dibenzo-p-dioxin-2-carboxylic acid and 7-amino-4-hydroxy-2-naphthalenesulfonic acid. Taken together with the response of topoisomerase to camptothecin and aminocatechol, these data suggest that there are sufficient structural differences between the topoisomerase I from Candida albicans and human cells to allow selective targeting of the fungal topoisomerase I over its human counterpart.
