  Inhibitory effects of a series of 7-substituted-indazoles toward nitric oxide synthases: Particular potency of 1H-indazole-7-carbonitrile

  摘要：

  A series of new 7-monosubstituted and 3,7-disubstituted indazoles have been prepared and evaluated as inhibitors of nitric oxide synthases (NOS). 1H-Indazole-7-carbonitrile (6) was found equipotent to 7-nitro-1H-indazole (1) and demonstrated preference for constitutive NOS over inducible NOS. By contrast, 1H-indazole-7-carboxamide (8) was slightly less potent but demonstrated a surprising selectivity for the neuronal NOS. Further substitution of 6 by a Br-atom at carbon-3 of the heterocycle enhanced 10-fold the inhibitory effects. Inhibition of NO formation by 6 appeared to be competitive versus both substrate and the cofactor (6R)-5,6,7,8-tetrahydro-L-biopterin (H4B). In close analogies with 1, compound 6 strongly inhibited the NADPH oxidase activity of nNOS and induced a spin state transition of the heme-Fe-III. Our results are explained with the help of the X-ray structures that identified key-features for binding of 1 at the active site of NOS. (C) 2008 Elsevier Ltd. All rights reserved.
