Fig. 1. H6-335 and H6-335-P1 reduce the c-di-GMP content in P. aeruginosa.
Effects of H6-335 (a) and H6-335-P1 (b) on the fluorescence output of the c-di-GMP monitor strain P. aeruginosa ΔwspFΔpelΔpsl/pCdrA-gfp. Bacteria were grown in the wells of microtiter plates in the presence of various concentrations of H6-335 or H6-335-P1. GFP fluorescence was measured every 20 min for 24 h. Specific c-di-GMP levels (GFP/OD600) are plotted as a function of time and H6-335 or H6-335-P1 concentration. Mean and standard deviation (bars) of three biological replicates (n = 3) are shown.
