In Vitro

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].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.08 mg/mL (7.70 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
