From Wikipedia:
" It showed activity against drug-resistant strains of Clostridium difficile, Acinetobacter baumannii, and Mycobacterium tuberculosis, with an unusual mechanism of action involving the sequestration of iron inside the bacterial cells which thereby interferes with their ability to properly regulate the pH balance across the cell membrane. Since this is a different mode of action from most antibiotics, halicin retained activity against bacterial strains resistant to many commonly used drugs."
