General description

Phloretin a polar dye belongs to the class of dihydrochalcones.
Major polyphenol found in apple; aglycone of phloridzin.

Application

Phloretin has been used:
  • to study its effect on the 2-[N-(7-Nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-2-deoxy-d-glucose (2-NBDG) and 2-[N-(7-Nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-2-deoxy-l-glucose (2-NBDLG) uptake
  • to incubate microvesicles in order to inhibit GLUT1 (glucose transporter 1)-mediated transport in radioactive ligand up-take assay
  • as a component of KRH buffer to stop glucose uptake by trophoblast cells in vitro

Biochem/physiol Actions

Blocks L-type Ca2+ channels; activates Ca2+-activated K+ channels in amphibian myelinated nerve fibers. Monocarboxylate transporter inhibitor.
Phloretin is known to decrease interfacial dipole potential of lipid bilayer. Phloretin possess antitumor action by preventing protein kinase C (PKC) activity and stimulating programmed cell death. It is found to inhibit the transport functions of GLUTs (glucose transporter) and aquaporins.
Reacts with vic-dicarbonyl compounds such as glyoxal and methylglyoxal, preventing cytotoxic conjugation with biological macromolecules.

Aerobic Glycolysis and the Warburg Effect

We presents an article about the Warburg effect, and how it is the enhanced conversion of glucose to lactate observed in tumor cells, even in the presence of normal levels of oxygen. Otto Heinrich Warburg demonstrated in 1924 that cancer cells show an increased dependence on glycolysis to meet their energy needs, regardless of whether they were well-oxygenated or not.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
