Galangin (Norizalpinin)?inhibits the catabolic breakdown of DMBA, as measured by thin-layer chromatography, in a dose-dependent manner.?Galangin?also inhibits the formation of DMBA-DNA adducts, and prevents DMBA-induced inhibition of cell growth.?Galangin?causes a potent, dose-dependent inhibition of?CYP1A1?activity, as measured by ethoxyresorufin-O-deethylase?activity, in intact cells and in microsomes isolated from DMBA-treated cells. Analysis of the inhibition kinetics by double-reciprocal plot demonstrates that?galangin?inhibits CYP1A1?activity?in a noncompetitive manner.?Galangin?causes an increase in the level of?CYP1A1?mRNA, indicating that it may be an?agonist?of the?aryl?hydrocarbon?receptor, but it inhibits the induction of?CYP1A1?mRNA by DMBA or by 2,3,5,7-tetrachlorodibenzo-p-dioxin (TCDD).?Galangin?also inhibits the DMBA- or TCDD-induced transcription of a reporter vector containing the?CYP1A1?promoter[1]. Galangin treatment inhibits cell proliferation and induced autophagy (130 μM) and apoptosis (370 μM). In particular, galangin treatment in HepG2 cells causes (1) an accumulation of autophagosomes, (2) elevated levels of microtubule-associated protein light chain 3, and (3) an increased percentage of cells with vacuoles. p53 expression is also increased. The galangin-induced autophagy is attenuated by the inhibition of p53 in HepG2 cells, and overexpression of p53 in Hep3B cells restored the galangin-induced higher percentage of cells with vacuoles to normal level[2].

Protocol
Cells (5.0×103) are seeded and treated with different concentrations of galangin for different periods of time in 96-well plates. The number of viable cells in each well is determined by adding 10 µL of 5 mg/mL MTT solution. Following the 4 hour incubation at 37°C, the cells are dissolved in a 100 µL solution containing 20% SDS and 50% dimethy formamide. The optical densities are quantified at a test wavelength of 570 nm with a reference wavelength of 630 nm using a Varioskan Flash Reader spectrophotometer.
