Figure 1. Chemical structure of tested substrates.

Figure 1

Chemical structures of (A.) phosphotriesters, (B.) CMP-coumarin, (C.) esters, (D.) Acyl-Homoserine Lactones, (E.) γ-lactones, (F.) δ-lactones and (G.) dihydrocoumarin are presented. For phosphotriesters, R corresponds to different nature of substituents; LG corresponds to the leaving group which can be F, S-R, O-R or CN. The terminal substituent could be S atom if the molecule is a thionophosphotriester or an O atom if the molecule is an oxonophosphotriester. For esters, R corresponds to different nature of substituent. For AHLs and γ/δ-lactones, R corresponds to different size of acyl chain.
