Structure based design of an in vivo active hydroxamic acid inhibitor of P. aeruginosa LpxC
摘要:
Lipid A is an essential component of the Gram negative outer membrane, which protects the bacterium from attack of many antibiotics. The Lipid A biosynthesis pathway is essential for Gram negative bacterial growth and is unique to these bacteria. The first committed step in Lipid A biosynthesis is catalysis by LpxC, a zinc dependent deacetylase. We show the design of an LpxC inhibitor utilizing a robust model which directed efficient design of picomolar inhibitors. Analysis of physiochemical properties drove design to focus on an optimal lipophilicity profile. Further structure based design took advantage of a conserved water network over the active site, and with the optimal lipophilicity profile, led to an improved LpxC inhibitor with in vivo activity against wild type Pseudomonas aeruginosa.
