An investigation into the effect of modified β-lysines on the growth rates of eubacterial cells is reported. It is shown that the effects observed are due to the post translational modification of Elongation Factor P (EFP) with these compounds catalysed by PoxA. PoxA was found to be remarkably promiscuous, which allowed the activity of a wide range of exogenous β-lysines to be examined. Two chain-elongated

In the lipid A biosynthetic pathway, the enzyme LpxH is a promising antibiotic drug target. In this work, several sulfonylpiperazineLpxHinhibitors were designed and synthesized. Among them, JH-LPH-50 shows improved activityagainstLpxH by chelating the dimanganese cluster in the active site of LpxH.
