  In vitro and in vivo studies of 6,8-(diaryl)imidazo[1,2-a]pyrazin-3(7H)-ones as new antioxidants

  摘要：

  A series of 5-aryl and 3,5-diaryl-2-amino-1,4-pyrazines and the derived imidazopyrazinones has been synthesized to study the chemical oxidative degradation of the bicyclic systems in vitro. Imidazopyrazinones mainly degraded following two independent pathways producing their precursors, namely aminopyrazines, and the corresponding amidopyrazines, respectively. Despite the fact that there is no influence of the substituent of the 3-aryl group on the ratio of the products aminopyrazine/amidopyrazine, diarylimidazopyrazinones and diarylaminopyrazines are good antioxidants in vivo. They protected against microvascular damages in ischemia/reperfusion with similar efficiencies. (C) 2009 Elsevier Ltd. All rights reserved.
