Notes: Fisetin-d5 is intended for use as an internal standard for the quantification of fisetin (Item No. 15246) by GC- or LC-MS. Fisetin is a flavonoid that has been found in various fruits and vegetables and has diverse biological activities.{61545,61546,61547,61548} It scavenges radicals in a Trolox equivalent antioxidant capacity (TEAC) assay and inhibits oxidative burst induced by N-Formyl-Met-Leu-Phe (fMLP; Item No. 21495) in isolated human polymorphonuclear neutrophils (PMNs) when used at a concentration of 10 µM.{61545,61547} Fisetin (10-60 µM) induces cell cycle arrest at the G1 phase and apoptosis in, as well as inhibits the proliferation of, LNCaP prostate cancer cells.{61546} It inhibits LPS-induced production of nitrite, prostaglandin E2 (PGE2; Item No. 14010), and NF-κB activation in RAW 264.7 cells.{61547} Fisetin (1 mg/animal) reduces tumor growth in a CWR22Rυ1 prostate cancer mouse xenograft model.{61548}
