Abstract

The formation of radical product ions from an antimicrobial prodrug DB289 and selected metabolites using ion trap mass spectrometry was investigated. The formation of an odd electron ion from an even electron ion with the loss of a radical was observed in the fragmentation patterns of DB289. The homolytic bond clevage was verified to occur using deuterium exchange and was observed consistently with this class of compounds. The results showed that the proposed homolytic bond cleavage as the lowest-energy reaction pathway for the molecular ion of DB289.
