GW-274150 [DBID]
  • Miscellaneous

    • Bio Activity:

      GW274150 is a novel arginine-competitive, NADPH-dependent iNOS inhibitor that has been identified from a series of acetamide amino acids that have a high selectivity for iNOS vs both eNOS (> 260-fold) and nNOS (> 219-fold) and high bioavailability (> 90%) after oral administration.;Target: iNOS;In vivo: GW274150 demonstrates a narrow neuroprotective therapeutic window against the toxic actions of 6-OHDA. GW274150 administration leads to a dose-dependent decrease in the number of iNOS-positive cells in the SNc of the 6-OHDA-lesioned animals. The iNOS inhibitor GW274150 fails to produce long-term neuroprotection after its withdrawal in the 6-OHDA-lesioned rat. [1] MedChem Express HY-12119
