[Description]

Hesperetin is a flavonoid that has been found in citrus fruits and has diverse biological activities. It reduces ApoB protein levels, ACAT2 expression, and LDL degradation in HepG2 cells when used at a concentrations ranging from 10 to 200 μM. Hesperetin inhibits IgG-induced β-hexosaminidase release from RBL-2H3 cells (IC50 = 0.099 mg/ml). It inhibits LPS-induced nitric oxide (NO) production and reduces levels of inducible nitric oxide synthase (iNOS), IL-6, and IL-1β in BV-2 microglial cells. Hesperetin (5 mg/kg) inhibits passive cutaneous anaphylaxis in mice. It reduces body weight loss, colon shortening, and ulcer severity in a mouse model of TNBS-induced ulcerative colitis. Hesperetin reduces cortical and hippocampal neuronal apoptosis and increases time spent in the target quadrant in the Morris water maze in a mouse model of LPS-induced neuronal inflammation.

antiallergic
[Uses]

The aglucon of Hesperidin (H281185), a flavanone found in citrus fruits.
[Definition]

ChEBI: A trihydroxyflavanone having the three hydroxy gropus located at the 3'-, 5- and 7-positions and an additional methoxy substituent at the 4'-position.
[Purification Methods]

Crystallise it from EtOAc or ethanol. The natural S(-) form crystallises from EtOH and has m 216-218o and [] D -37.6o (c 2, EtOH). Note that C2 is chiral. [Beilstein 18 II 204, 18 III/IV 3215, 18/5 V 214.]
