Activity of ketoconazole and its deacyl derivative against Plasmodium falciparum and Candida isolates

Deacylketoconazole was 15- to 50-fold more active against Plasmodium falciparum than was ketoconazole, based on [(3)H]hypoxanthine uptake and quantitative parasite counts. In contrast, there were no significant differences between these drugs in their activity against clinical isolates of Candida spp.
