biosynthesis of lipid A, is crucial for the growth of Gram‐negative bacteria. This enzyme has accordingly been identified as a potential target for the development of novel antibiotics against Gram‐negative bacteria. The carbohydrate‐derived hydroxamic acid 1 (1,5‐anhydro‐2‐C‐(carboxymethyl N‐hydroxyamide)‐2‐deoxy‐3‐O‐myristoyl‐ D‐glucitol) was previously shown to exhibit a wide spectrum of inhibitory activity
