Theoretical calculations of a model of NOS indazole inhibitors: Interaction of aromatic compounds with Zn-porphyrins Original Research Article

We report a theoretical approach, at the M05-2x/6-311+G(d) level, to explain the affinity of indazoles for nitric oxide synthases using a simplified model of porphyrin. The theoretical Erel = Ei stacking–Ei apical values correlate with the experimental inhibition percents allowing to predict that 3,7-dinitro-1H-indazole should be a good NOS inhibitor.
