^aNumber of analyzed interactions, i.e. three docking runs for each variant.

^bCoefficients of the linear regression equation fitting the experimental data. In detail, the equation is in the form Y = A + BX, where Y is the experimental ΔG° expressed in kcal/mol, A (kcal/mol) is the intercept, B (kcal/mol) is the slope and X is the corresponding ZD-s component.

^cLinear correlation coefficient.

^dLinear correlation coefficient probability.

^eData referring to the protonated form of H102^Bn.

^fData referring to the neutral form of H102^Bn.
