 $^{\rm a}$ Obtained using Alphascreen; $^{\rm b}$ Obtained using Isothermal Titration Calorimetry; $^{\rm c}$ not determined; $^{\rm d}$ Non-binder (inactive at 250$\mu$M); $^{\rm e}$ PubChem compound ID.; $^{\rm f}$ No saturation (32\% inhibition at 250$\mu$M). 
+Experimental values for cases $^{\rm d}$ and $^{\rm f}$ may not be as high quality as could be desired; however, these cases can still serve very well for method validation when comparison against experiment is a more minor consideration.
