Literature evidence Flavonoids inhibit cell proliferation and induce apoptosis and autophagy through downregulation of PI3Kγ mediated PI3K/AKT/mTOR/p70S6K/ULK signaling pathway in human breast cancer cells.
IUPAC name 3,5,7-trihydroxy-2-(4-hydroxy-3-methoxyphenyl)chromen-4-one

Plant parts Whole plant
Other cancers Breast cancer
Target gene or protein MMP2, MMP9, p38 MAPK, STAT-3
Gene or Protein evidence Taken together, these data demonstrated that isorhamnetin could significantly inhibit the invasion of MDA-MB-231 cells by downregulating the expression and activity of MMP-2 and MMP-9, which was potentially associated with the suppression of p38 MAPK and STAT3.
Target pathways PI3K/AKT/mTOR/p70S6K/ULK signaling pathway PI3K/Akt and NF- κ B Pathways
IC50 NA
Potency Importantly, treatment with these flavonoids decreased the levels of PI3Kγ-p110, phospho-PI3K, phospho-AKT, phospho-mTOR, phospho-p70S6K, and phospho-ULK. Pretreatment with PI3Kγ specific inhibitor AS605240 potentiated flavonoids-mediated inactivation of AKT, mTOR, p70S6K, ULK, and apoptosis.
Cell line/ mice model B16F10, MCF-7, MDA-MB-231
Additional information  The examination on molecular mechanism revealed that IH could suppress the phosphorylation of Akt and the translocation of NF-κB, which are key factors in apoptosis-related pathways. We also detected that this process was related to the bifunctional 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatases 4 (PFKFB4) by PFKFB4 knockdown experiment.
