This Table contains the Emax, EC50 and Hill slope data for the data presented in Figure 2. The data represent the mean ± SEM or 95% confidence intervals from at least three separate experiments for each compound. The 95% confidence interval is given for the EC50 data because the error is not symmetrically distributed around the mean. The asterisk indicates significant difference from the corresponding CP55 940 value.
