CYP51
Mechanisms of ResistanceNew Insights into the Cyp51 Contribution to Azole Resistance in Aspergillus Section NigriInvasive aspergillosis (IA) is a severe condition mainly caused by Aspergillus fumigatus, although other species of the genus, such as section Nigri members, can also be involved. Voriconazole (VRC) is the recommended treatment for IA; however, the prevalence of azole-resistant Aspergillus isolates has alarmingly increased in recent years, and the...
Experimental TherapeuticsAzole Resistance Reduces Susceptibility to the Tetrazole Antifungal VT-1161Tetrazole antifungals designed to target fungal lanosterol 14α-demethylase (LDM) appear to be effective against a range of fungal pathogens. In addition, a crystal structure of the catalytic domain of Candida albicans LDM in complex with the tetrazole VT-1161 has been obtained.
- Mechanisms of ResistanceIdentification of 14-α-Lanosterol Demethylase (CYP51) in Scedosporium Species
Scedosporium spp. cause infections (scedosporiosis) in both immunocompetent and immunocompromised individuals and may persistently colonize the respiratory tract in patients with cystic fibrosis (CF).
- Mechanisms of ResistanceMolecular Confirmation of the Linkage between the Rhizopus oryzae CYP51A Gene Coding Region and Its Intrinsic Voriconazole and Fluconazole Resistance
Rhizopus oryzae is the most prevalent causative agent of mucormycosis, an increasingly reported opportunistic fungal infection. These Mucorales are intrinsically resistant to Candida- and Aspergillus-active antifungal azole drugs...
