用途
使用
A human metabolite of Resveratrol (R150000). Piceatannol is strong anti-oxidant.
一般的な説明
A cell-permeable, substrate competitive and reversible plant metabolite that inhibits the activity of rat liver protein kinase A catalytic subunit (IC50 = 3 μM), PKC (IC50 = 8 μM), MLCK (IC50 = 12 μM). In RBL-2H3 cells, the selective inhibition of Syk by piceatannol results in inhibition of FceR1-mediated signaling. Also inhibits wheat embryo Ca2+-dependent protein kinase (CDPK) (IC50 = 19 μM), and p72syk (IC50 = 10 μM), a non-receptor tyrosine kinase, relative to Lyn in isolated enzyme preparations. Also possesses anti-leukemic properties. Reported to activate sirtuins and promote the survival of eukaryotic cells.
