Investigation and conformational analysis of fluorinated nucleoside antibiotics targeting siderophore biosynthesis.

ABSTRACT: Antibiotic resistance represents one of the greatest threats to public health. The adenylation inhibitor 5'-O-[N-(salicyl)sulfamoyl]adenosine (SAL-AMS) is the archetype for a new class of nucleoside antibiotics that target iron acquisition in pathogenic microorganisms and is especially effective against Mycobacterium tuberculosis, the causative agent of tuberculosis. Strategic incorporation of fluorine at the 2' and 3' positions of the nucleoside was performed by direct fluorination to enhance activity and improve drug disposition properties. The resulting SAL-AMS analogues were comprehensively assessed for biochemical potency, whole-cell antitubercular activity, and in vivo pharmacokinetic parameters. Conformational analysis suggested a strong preference of fluorinated sugar rings for eit
