标题:Oroxylin A Analogs Exhibited Strong Inhibitory Activities Against Inos-Mediated Nitric Oxide (No) Production
摘要:A Number Of Oroxylin A Analogs Were Prepared And Evaluated For Their Inhibitory Activities Against Inos-Mediated Nitric Oxide (No) Production From Lps-Stimulated Bv2 Cells. The Analogs Were Synthesized From Purchased 2'-Hydroxy-4,5,6-Trimethoxyacetophenone And Aldehydes In 3 Steps. Among The Tested Compounds,Several Analogs (3B,3C,3D,3F) Exhibited Strong Inhibitory Activities. Especially,The Analog With 4-Nitrophenyl Group (3B) Showed Stronger Inhibitory Activity (Ic50 = 4.73 Mu M) Than That Of Wogonin (Ic50 = 7.80 Mu M). (C) 2012 Published By Elsevier Ltd.
