  Design and Synthesis of Orally Bioavailable Inhibitors of Inducible Nitric Oxide Synthase. Identification of 2-Azabicyclo[4.1.0]heptan-3-imines

  摘要：

  Further chemical modification of 2-iminopiperidines fused to cyclopropane rings was performed. Optically active isomers 2 and 13 were synthesized and their biological activity was evaluated. Compound 2 exhibited greater potency and more isoform selectivity than enantiomer 13 in the iNOS inhibition assay. One of the gem-chlorines on the fused cyclopropane moiety of 2 was eliminated to produce 3, which showed reduced potency for iNOS inhibition, as well as 4 with an increased potency. The isoform selectivity of 4 was also much higher than that of 3. This was also true for the corresponding methyl derivatives 6-9. The structure-activity relationship (SAR) study and computer aided docking study of the most optimized structure 4 with human iNOS will also be reported. (C) 2003 Elsevier Science Ltd.
