A primary strategy to combat antimicrobial resistance is the identification of novel therapeutic targets and anti-infectives with alternative mechanisms of action. The inhibition of the metalloenzymes carbonic anhydrases (CAs, EC 4.2.1.1) from pathogens (bacteria, fungi, and protozoa) was shown to produce an impairment of the microorganism growth and virulence. As phosphonamidates have been recently validated as human ?-CA inhibitors (CAIs) and no phosphorus-based zinc-binding group have been assessed to date against ?-class CAs, herein we report an inhibition study with this class of compounds against ?-CAs from pathogenic bacteria, fungi, and protozoa. Our data suggest that phosphonamidates are among the CAIs with the best selectivity for ?-class over human isozymes, making them interesting leads for the development of new anti-infectives.

Abstract
A primary strategy to combat antimicrobial resistance is the identification of novel therapeutic targets and anti-infectives with alternative mechanisms of action. The inhibition of the metalloenzymes carbonic anhydrases (CAs, EC 4.2.1.1) from pathogens (bacteria, fungi, and protozoa) was shown to produce an impairment of the microorganism growth and virulence. As phosphonamidates have been recently validated as human ?-CA inhibitors (CAIs) and no phosphorus-based zinc-binding group have been assessed to date against ?-class CAs, herein we report an inhibition study with this class of compounds against ?-CAs from pathogenic bacteria, fungi, and protozoa. Our data suggest that phosphonamidates are among the CAIs with the best selectivity for ?-class over human isozymes, making them interesting leads for the development of new anti-infectives.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
