摘要

N,O-Didansyl-L-tyrosine (DDT) represented the starting lead for further development of novel non-substrate-like inhibitors of bacterial thymidylate synthase. The N-dansyl structure modulation led to a submicromolar inhibitor of Lactobacillus casei TS (LcTS), which is highly specific with respect to human TS (hTS). Using molecular dynamics simulation, a binding mode for DDT vs LcTS was predicted, explaining activity and species-specificity along the series.
