Antimicrobial
Nitrofurantoin
Reactive-intermediate urinary agent
ny-troh-fyoor-AN-toyn
High-yield clue
Bacterial nitroreductases convert nitrofurantoin into reactive intermediates that attack DNA and ribosomes, and it concentrates in urine.
Overview
A synthetic nitrofuran studied as a urinary-concentrated agent whose bacterial nitroreductases generate reactive intermediates that damage multiple microbial targets.
