Tectorigenin is a plant isoflavonoid originally isolated from the dried flower of Pueraria thomsonii Benth.

Tectorigenin is a plant isoflavonoid originally isolated from the dried flower of Pueraria thomsonii Benth. Palmitic acid (PA)-stimulated ROS production is abolished by treatment with Tectorigenin for HUVECs in a dose-dependent manner (0.1, 1, 10 μM). Treatment with Tectorigenin attenuates enhanced IKKβ phosphorylation and effectively blocks NF-κB activation by inhibition of p65 phosphorylation at concentrations ranging from 0.1 to 10 μM. Tectorigenin treatment also effectively inhibits PA-augmented TNF-α and IL-6 production in a concentration dependent manner^[1]. The number of viable HepG2 cells treated by Tectorigenin decreases in a concentration- and time-dependent manner. When HepG2 cells are treated with Tectorigenin at 5, 10 and 20 mg/L for 24 h, the viability rate is 91%, 79% and 62%, respectively^[2].

HUVECs grown to confluence in 24-well plates are pretreated with Tectorigenin (0.1, 1, 10 μM), salicylate (5 mM) or GSH (1 mM) for 30 min, then stimulated with Palmitic acid (PA) (100 μM) for further 12 h in serum-free medium, and the medium is then collected on ice. The levels of TNF-α and IL-6 in the supernatant are assayed with commercial ELISA Kits^[1].

Cell viability is assessed by MTT method. Briefly, cells are seeded in 96-well plate at a density of 1×10⁴ cells/well. After 24 h incubation, Tectorigenin at different concentrations is added to the cells while only DMSO (solvent) is added as a negative control. After growing for 12, 24 and 48 h, cells are incubated with MTT (0.5 mg/mL) for 4 h at 37°C. During this incubation period, water-insoluble formazan crystals are formed, which are dissolved by the addition of 100 μL/well DMSO. The optical densities at 570 nm are measured using an enzyme-linked immunosorbent assay plate reader. Wells containing culture medium and MTT but no cells act as blanks^[2].
