Alkane-1-N-butylcarbamate-n-ols (1-7) and 1,n-alkane-di-N-butylcarbamates (8-14) are potent pseudo-substrate inhibitors of acetylcholinesterase. For inhibitors 1-7, the pre-steady state -logK(s) values and steady state -logK(i), values are linearly correlated with the tether length (N). However, for inhibitors 8-14, correlation of the -logK(s) or -logK(i) values against N deviates from linearity. A discontinuity of the -logK(s) versus N plot, concave downwards, is indicative of a rate determining step change in the pre-steady state of acetylcholinesterase inhibitions by inhibitors 8-14.
