General description

Tangeretin is a polymethoxyflavone extracted primarily from the peels of citrus fruits like Citrus sinensis and Citrus reticulata.

Application

Tangeretin 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.

Biochem/physiol Actions

Tangeretin displays its anti-cancer effects by modulating different pathways in several cancer types in both in-vitro and in-vivo studies. It also exerts antioxidant, anti-inflammatory, and estrogenic properties.
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.

A series of 3'-aminoflavones 5,6,7,8-tetra- or 5,7-dioxygenated on the A-ring was synthesized from tangeretin or naringin, two natural Citrus flavonoids. These flavones were evaluated for antiproliferative activity, activation of apoptosis, and inhibition of tubulin assembly. The most antiproliferative flavones exhibit

Unregulated uptake of oxidized low-density lipoproteins (ox-LDL) via macrophage scavenger receptors (SRs) is a key event in atherosclerosis. We previously reported that nobiletin (NOB), a citrus polymethoxylated flavone, markedly reduced 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced SRs and adhesion molecules mRNA expression and blockade

The present study examined the effects of tangeretin, a polymethoxylated flavonone present in citrus fruits, on ultraviolet B (UVB)-induced cyclooxygenase-2 (COX-2) expression in JB6 P+ mouse skin epidermal cells. Tangeretin suppressed UVB-induced COX-2 expression and transactivation of nuclear factor-κB and
