Structure activity relationship studies of cinnamic acid derivatives as inhibitors of human neutrophil elastase revealed by ligand docking calculations.
Structure-activity relationship of cinnamic acid derivatives as inhibitors of the human neutrophil elastase is reported. Comparison of the inhibitory concentrations (IC50 values) with the results of the ligand docking calculations revealed that the structure element of the aromatic ortho-dihydroxy groups combined with a lipophilic residue seems to be a prerequisite for an optimal binding within the active site.
