Here we demonstrate that in interbacterial quorum signal moderators, N-acylhomoserine lactones (AHLs), the stabilization of bioactive pharmacophore lactone against lysis is through the e(-) withdrawing N-acyl motif which reduces lactone carbonyl polarization. This lysis is assisted by weak (<0.05 kcal mol(-1)) contacts between N-acyl O and lactone C'. The interactions that preclude this weak contact, in the free and receptor-bound AHLs, improve lactone halflife and hence are key to the design of the antibacterial AHL analogues.
