Chemical Properties:
  1. Fisetin (Fisetin) is a polymer pharmaceutical raw material. This product is yellow needle-like crystals, derived from RhussuccedaneaL, Cotinus coggygria, and so on. Soluble in ethanol, acetone and acetic acid. Almost insoluble in water, ether, benzene, chloroform and petroleum ether. It has an inhibitory effect on the production of prostatic cord in the fibroblasts of 3T3 mice transformed and mutated by methylcholanthrene.
  2. The effective inhibitory concentration (ID50) of the half of the Chemicalbook is 42.0UM. It has an inhibitory effect on the whole sugar reductase of rat eye lens, and the half effective inhibitory concentration is 10-6M; for mouse small intestine specimens, its anti-spasmodic effect of acetylcholine is 166% of papaverine. A team of researchers from Japan and the United States found through animal experiments that the lacxanthin in vegetables and fruits helps improve memory.
  1. Fisetin is a plant polyphenol from the flavonoid group. It occurs in fruits and vegetablesincluding persimmons, strawberries, onions, cucumbers, and apples.
  2. It is anantioxidant, exerts anticarcinogenic effects in HCT-116 (human colon carcinoma)cells, and modulates protein kinase and lipid kinase pathways (Wang et al. 2012).Fisetin alter signaling pathway like MAPK, NF-κB, activators of transcription(JAK/STAT), Janus kinase/signal transducers, phosphoinositide-3-kinase-proteinkinase (PI3K/Akt), Wnt, and mammalian target of rapamycin (mTOR), therebyleading to cell cycle arrest in HL-60 cells (human acute promyelocytic leukemiacells) (Singh et al. 2016b). Thus, it exhibits inhibitory effects on adhesion, migration,invasion, and multidrug resistance (Suh et al. 2009).
