The inhibition of neuronal and inducible nitric oxide synthases (nNOS and iNOS) by a series of 36 indazoles has been evaluated, showing that most of the assayed derivatives are better iNOS than nNOS inhibitors. A parabolic model relating the iNOS inhibition percentage with the difference, Erel, between stacking and apical interaction energies of indazoles with the active site of the NOS enzyme has been established.
