Columns 2-5 indicate the parameters for the best fit to the logistic equation f=min + (max-min)/(1+(x/EC50)^ (-Hillslope)), which was used to fit the concentration-protection curves of cembranoids in column 1 (also see Figures 7A-7F). All regression coefficients were > 0.9. The QSAR number is defined in Table 2.
