appropriate lipophilic fragments for lead optimization. More potent and selectiveinhibitors with better druglike properties were obtained within the design of 20 derivatives (compounds 7−26). Our structure-basedinhibitor design for nNOS and SAR analysis reveal the robustness and efficiency of fragment hopping in lead discovery and structural optimization, which implicates a broad application of this
