Novel hybrids of 3-n-butylphthalide and edaravone: Design, synthesis and evaluations as potential anti-ischemic stroke agents
摘要:
Fourteen hybrids (10a-g, 11a-g) of 3-n-butylphthalide (NBP) and edaravone (Eda) analogues have been designed and synthesized as potential anti-ischemic stroke agents. In vitro biological studies showed that compounds 10d and 10g exhibited more potent anti-platelet aggregation than ticlopidine (Ticlid), aspirin (ASP) and NBP. Compound 10g more significantly prevented H2O2-mediated neuronal cell (PC12) death than NBP, Eda or NBP together with Eda. Meanwhile, 10g also possessed potent radical scavenging effects on hydroxyl radical ((OH)-O-center dot) and superoxide anion radical (O-center dot(2)-). Our findings may provide new insights into the development of these hybrids, like 10g, for the intervention of ischemic stroke. (C) 2015 Elsevier Ltd. All rights reserved.
