Description générale

Isorhamnetin is an O-methylated flavonol found in fruits, plants, and medicinal herbs. It is a metabolite of quercetin.

Application

Isorhamnetin (IRN) has been used:
  • as a neuroprotective agent to test its effect on scopolamine-induced cortico-hippocampal learning and memory deficiency in mice
  • as a reference standard in quadrupole time-of-flight mass spectrometry (QTOF MS) to analyze and quantify the phenolic compounds present in honey extract
  • as a reference standard to determine the phenolic profile of Artemisia species using Reversed-phase high-performance liquid chromatography with diode array detection and electrospray ionization mass spectrometry (RP-HPLC-DAD-ESI-TQ-MS/MS)

Actions biochimiques/physiologiques

Isorhamnetin exerts antioxidant, anti-inflammatory, anti-cancer, anti-bacterial, and anti-viral effects. It has shown to be a potential neuroprotective agent by inhibiting neurodegeneration in the hippocampus under Diabetes mellitus (DM) conditions. Isorhamnetin at low levels may serve as an anti-diabetic agent by promoting glucose uptake in skeletal muscle cells and maintaining glucose homeostasis in hyperglycemic conditions. It regulates cell signaling pathways such as Nuclear factor kappa B (NF-κB), phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT), mitogen-activated protein kinase (MAPK) etc. Isorhamnetin elicits protective and therapeutic effects on atherosclerosis and cardiovascular diseases.
Isorhamnetin inhibits adipogenesis by interfering with differentiation of adipose stem cells, by a mechanism involving stabilization of β-catenin and up-regulating the Wnt signaling pathway.
