Ortho-substituted phenyl-N-butyl carbamates (1–11) were synthesized to evaluate the inhibition mechanisms of porcine pancreatic cholesterol esterase. All carbamate inhibitors act as the active site-directed pseudo substrate inhibitors of the enzymes. The logarithms of dissociation constant (Ki), carbamylation constant (k2) and bimolecular inhibition constant (ki) multiply linearly correlate with the
