N-(4-aryl) position in 3,3-diethyl- N-aryl derivatives increasing the rate of enzyme acylation and generating a Hammett rho-value of 0.65. Compared with a rho-value of 0.96 for the rates of alkaline hydrolysis of the same series, this is indicative of an earlier transition state for the enzyme-catalyzed reaction. Docking studies indicate favorable noncovalent interactions of the inhibitor with the enzyme
