  • PubMed Abstract: 

    The two front-line drugs for chronic Trypanosoma cruzi infections are limited by adverse side-effects and declining efficacy. One potential new target for Chagas' disease chemotherapy is sterol 14alpha-demethylase (CYP51), a cytochrome P450 enzyme involved in biosynthesis of membrane sterols.
