Stability constants (Ks) were obtained by 1H-NMR titration experiments, performed directly in the NMR tube using a micropipette to add known amounts (0, 50, 100, 150, 200, 250, 300, 350, 400, 450, 500 μl) of quaternary ammonium salt (2) stock solution (concentration, 10.0 mM) in CDCl3 to a solution of indolylmethanes (1, 700 μl, concentration, 5.76 mM) in CDCl3. A 1:1 association of indolylmethanes (1) and quaternary ammonium salts (2) was previously demonstrated by Job plots, therefore, experimental data were fit to the equation of the 1:1 binding isotherm. All titration experiments were performed in CDCl3 at 297 K and 500 MHz
