title: Synthesis and PGE2 inhibitory activity of vinylated and allylated chrysin analogues.
abstract: Vinylated and allylated chrysin analogues were prepared as congeners of prenylated flavonoids and evaluated their anti-inflammatory activity. 8-Substituted chrysin analogues were prepared from 2'-hydroxy-3'-iodo-4',6'-dimethoxyacetophenone in 3 steps. 3-Allylated chrysin analogues were prepared from chrysin in 3 steps. Synthesized chrysin analogues (4, 5 and 8) showed moderate inhibitory activities of PGE2 production from LPS-induced RAW 264.7 cells.
