3,7-Dihydroxyflavone
Based on 1 Customer Validation
3,7-Dihydroxyflavone (Resogalangin) is a flavonoid phytoestrogen, which can be isolated from Adenophora species. 3,7-Dihydroxyflavone is a modulator of estrogen receptors and an inhibitor of human progesterone metabolizing enzyme AKR1C1 and fungal 17β-hydroxysteroid dehydrogenase and a redox inhibitor (IC50=0.6 and 6.0 μM, respectively). 3,7-Dihydroxyflavone is a fluorescent binding substrate for human serum albumin (HSA) with excitation wavelengths of 370 nm (pH 7.4) and 350 nm (pH 3.5), respectively, and emission wavelength of 515 nm.

For fluorescence assay with 3,7-Dihydroxyflavone and HSA, a stock solution of 3,7-Dihydroxyflavone was prepared in methanol with a final methanol concentration of less than 4% (v/v). Note that the pH of the phosphate buffer solution was adjusted to 3.5 and 7.4 with NaOH or H3PO4 solutions. The ionic strength of the solution was maintained at 0.1 M using NaCl solution. The experimental temperature was 25°C[1].
Isopentenyl derivatives of 3,7-Dihydroxyflavone can inhibit tumor cell growth and proliferation and induce apoptosis[2].
