Investigation and Conformational Analysis of Fluorinated Nucleoside Antibiotics Targeting Siderophore Biosynthesis

(Chemical Equation Presented) 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 either a 2′-endo, 3′-exo (South), or a 3′-endo,2′-exo (North) conformation. The structure-activity relationships revealed a strong conformational bias for the C3′-endo conformation to maintain potent biochemical and whole-cell activity, whereas improved pharmacokinetic properties were associated with the C2′-endo conformation.

SYNTHESIS OF OLIGORIBONUCLEOTIDES USING 4-METHOXYBENZYL GROUP AS A NEW PROTECTING GROUP OF THE 2'-HYDROXYL GROUP OF ADENOSINE

4-Methoxybenzyl group was introduced directlyto the 2'-hydroxyl group from the reaction of adenosine with 4-methoxybenzyl bromide in the presence of sodium hydride.The 2'-O-(4-methoxybenzyl)-adenosine can be successfully used in the synthesis of oligoribo
