摘要

4, 4-Difluoro-l-arginine and 4, 4-difluoro-NG-hydroxy-l-arginine were synthesized and shown to be substrates for the inducible isoform of nitric oxide synthase (iNOS). Binding of both fluorinated analogues to the NOS active site was also investigated using a spectral binding assay employing a heme domain construct of the inducible NOS isoform (iNOSheme). 4, 4-Difluoro-NG-hydroxy-arginine was found to bind at the NOS active site ...
