Suzuki. Heck and Sonogishira coupling reactions of paramagnetic vinyl bromides 1-6 gave monofunctional (7a,b), homobifunctional (8a,b, 24), and heterobifunctional pyrroline nitroxide; (9-19, 31) under mild conditions in aone-step reaction. From these compounds thiol-specific spin labels 26 and 28 and pyrroline nitroxide annulated heterocycles 30 and 32 were synthesized. The ethynyl derivative of pyrroline

New resveratrol analogues containing five- and six-membered nitroxides and isoindoline nitroxides were synthesized. These new compounds were compared to resveratrol based on their ABTS radical scavenging ability as well on their capacity to suppress inflammatory process in macrophages induced by lipopolysaccharides. The ABTS and ROS scavenging activities of new molecules were the same or weaker than that of resveratrol, but some of paramagnetic resveratrol derivatives suppressed nitrite and TNF alpha production more efficiently than resveratrol. Based on these results the new nitroxide and phenol containing hybrid molecules can be considered as new antioxidant and anti-inflammatory agents. (C) 2011 Elsevier Ltd. All rights reserved.
