Phosphoramidates are increasingly recognized as important molecular targets for therapeutic development. This study synthesized novel carbohydrate-based phosphoramidate derivatives and evaluated their adjuvant activity in combination with antibiotics, achieving good yields. The fluorinated glucose derivative of phosphoramidate showed remarkable efficacy against Methicillin-resistant S. aureus, with a 32-fold decrease in the MIC of Ampicillin.
Phosphoramidates are becoming increasingly recognized as molecular targets for therapeutic development. Their biological functions are significantly influenced by their inherent properties such as reactivity, as well as the P-N backbone which allows for structural diversity. In this study we report the synthesis of novel carbohydrate-based phosphoramidate derivatives via the Staudinger-phosphite reaction; along with an evaluation of their adjuvant activity in combination with popular antibiotics. Our targets involved variation in both the sugar residue as well as the identity of the phosphoramidate. Moderate to excellent yields of these derivatives were obtained. Notable adjuvant activity was observed with the halogenated phosphoramidates. For the fluorinated glucose derivative in particular, a remarkable 32-fold decrease in the MIC of Ampicillin was obtained against Methicillin-resistant S. aureus.
