Biological Activity

Description Galloflavin (NSC 107022) is a novel inhibitor of lactate dehydrogenasee (LDH) with Ki values of 5.46 μM and 15.06 μM for LDH-A and LDH-B, respectively.

(Cell-free assay)
5.46 µM(Ki) 15.06 µM(Ki)
In vitro
In vitro

Galloflavin inhibits both human LDH isoforms by preferentially binding the free enzyme, without competing with the substrate or cofactor. The calculated Ki values for pyruvate are 5.46 mm (LDH-A) and 15.06 mm (LDH-B). In cultured tumor cells, galloflavin blocks aerobic glycolysis at micromolar concentrations,  not interferes with cell respiration, and induces cell death by triggering apoptosis.[1]
Kinase Assay LDH activity assay
Human LDH-A (from human liver) and LDH-B (from human heart) are added in scalar amounts (0– 500 mm final concentrations) to a reaction mix containing 100 mm phosphate buffer (pH 7.5), LDH (0.015 UmL-1), 1 mm pyruvate, and 150 mm NADH. The enzymatic activity is measured by monitoring NADH oxidation for a period of 3 min (lex= 340 nm, lem =460 nm).
Cell Research Cell lines PLC/PRF/5 cell line
Concentrations 0.1–500 μM
Incubation Time 3 h
Method

PLC/PRF/5 cells (1.6 × 104 per well) are seeded in 24-well plates, allowed to adhere overnight, and treated for 72 h at 37 ℃ with  0–500 μM dose of Galloflavin. After the treatments, cells are used for assay of lactic acid production, cellular respiration and cell proliferation.
In Vivo
In vivo

Galloflavin treatment attenuates the malignant and invasion abilities of colon cancer cells in tumor-bearing mice, which are inhibited by the knockout of NLRP3.[2]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
