  Tangeretin[481-53-8] has been used as an antioxidant and antifungal agent to test its effects on ferroptosis inhibition, conidial development, and appressorium formation against Magnaporthe oryzae. It has also been used as a co-chemotherapeutics agent to study its cytotoxic effects in combination with 5-Fluorouracil (5-Fu) on WiDr colon cancer cells. |  [Definition]
  ChEBI: Tangeretin is a pentamethoxyflavone flavone with methoxy groups at positions 4', 5, 6 , 7 and 8. It has a role as an antineoplastic agent and a plant metabolite. |  [General Description]
  Tangeretin is a polymethoxyflavone extracted primarily from the peels of citrus fruits like Citrus sinensis and Citrus reticulata. |  [Biological Activity]
  Tangeretin is a flavonoid found in the peel of citrus fruits where it most likely provides natural resistance to fungi.  Tangeretin has been shown to counteract tumor promoter-induced inhibition of intercellular communication and to inhibit cell proliferation in several cancer lines. |  [in vivo]
 
 In this study, we investigated the in vivo anti-RSV activity of tangeretin in 3-week-old male BALB/c mice. A plaque reduction assay and fluorescence quantitative polymerase chain reaction (FQ-PCR) showed that tangeretin inhibited RSV replication in the lung of mice[2].  |  [References]
