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.

In Vitro
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].

ROS/oxidative-stress fluorescent staining
ROS/oxidative-stress fluorescent staining uses cell-permeant fluorogenic probes that become fluorescent after oxidation inside cells or tissues; commonly used examples include DCFH-DA/DCFDA for broad cellular oxidant detection, DHE for superoxide-related signal detection, MitoSOX for mitochondrial superoxide-related signal detection, and CellROX probes for oxidative-stress-associated fluorescence readouts. The assay detects probe oxidation rather than a single ROS species unless the probe and analysis method have been chemically validated for that species. DCFH-DA enters cells, is deacetylated by intracellular esterases to DCFH, and produces fluorescent DCF after oxidation, so the readout is used as an operational measure of total cellular oxidative stress rather than a species-specific ROS measurement. DHE and MitoSOX can report superoxide-related oxidation, but red fluorescence alone can include non-specific ethidium-like oxidation products; HPLC or optimized spectral approaches are

Research Protocol for Endocrine Diseases
Endocrine diseases often arise from disrupted hormone production, hormone signaling, or target-tissue responsiveness; for diabetes-focused endocrine disease models, insulin signaling regulates glucose uptake, hepatic glucose output, lipid metabolism, and β-cell compensation. Type 2 diabetes develops through interacting defects in insulin resistance, β-cell dysfunction, adipose inflammation, hepatic glucose overproduction, altered incretin signaling, and ectopic lipid metabolism. A major unresolved question is whether endocrine dysfunction is driven primarily by target-tissue insulin resistance, intrinsic β-cell failure, immune/inflammatory stress, or combined multi-organ failure that differs by disease stage.
