  4-Substituted indazoles as new inhibitors of neuronal nitric oxide synthase

  摘要：

  A series of halo-1-H-indazoles has been synthesized and evaluated for its inhibitory activity on neuronal nitric oxide synthase. Introduction of bromine at the C4 position of the indazole ring system provided a compound almost as potent as the reference compound, that is, 7-nitroindazole (7-NI). The importance of position 4 is further demonstrated by the synthesis and pharmacological evaluation of the 4-nitroindazole which was also a potent inhibitor of NOS activity. These compounds also exhibited in vivo NOS inhibitory activity, as attested by potent antinociceptive effects following systemic administration. (C) 2007 Elsevier Ltd. All rights reserved.

  The catalytic union of amides, sulfonamides, anilines, imines, or N-heterocycles with a broad spectrum of electronically and sterically diverse alkyl bromides has been achieved via a visible-light-induced metallaphotoredox platform. The use of a halogen abstraction-radical capture (HARC) mechanism allows for room temperature coupling of C(sp3)-bromides using simple Cu(II) salts, effectively bypassing
