Abstract

Effects of genistein analogs on oxygen radical production have been analyzed in human neutrophils, human monocytes or murine macrophages Raw264.7 stimulated with unopsonized zymosan by lucigenin- and luminol-enhanced chemiluminescence assays. Genistein exhibited IC50 values of 10.7 - 11.5 μM on the oxygen radical production in human neutrophils, 10.9 - 11.0 μM in human monocytes, and 14.8 - 27.3 μM in Raw264.7 cells. Orobol, a genistein analog with an additional hydroxy group at the 3′ position, exhibited IC50 values of 3.0 - 3.3 μM on the oxygen radical production in human neutrophils, 2.8 - 3.1 μM in human monocytes, and 1.5 - 3.9 μM in Raw264.7 cells. Genistin and sophoricoside are genistein glycosides with a glucose moiety at 7 or 4′ position, respectively. The genistein glycosides exhibited 23 - 37 % inhibitory effects at 100 μM on the oxygen radical production.
