  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.
