To test the effect of the compounds with respect to a possible antagonism, capsaicin was used at an approximate concentration CE8o of 0.05 μ? . For the pH experiments, a buffered solution of low pH [2- [N-morpholino] -ethanesulfonic acid (M ES) 60 mM in SSBH] was added to the test wells, to produce a final pH of 5.5. To determine the antagonist Cl50 values (concentrations of the antagonist that inhibits the response either at pH 5.5 or at capsaicin, by 50%), at least 10 antagonist concentrations were measured in duplicate. The response in the presence of the antagonist, was calculated as a percentage of the control response to capsaicin or at low pH, and plotted against the concentration of antagonist. The Cl50 was estimated by a non-linear regression analysis, sigmoid-logistic curves, with the Activity-Base software (v 5.0.1 0) or the M icrocal Origina software (v 7.03). These values were averaged (mean and standard error of the mean) for at least three independent experiments.
