Application

Lonidamine has been used:
  • as an inhibitor of glycolysis to study its effects on the epithelial-mesenchymal transition (EMT) mechanism in cancer stem cells (CSC)
  • as mitochondrial permeability transition (MPT)- inducing drug to study its effects on temozolomide-resistant glioblastoma cell line
  • as mitochondrial hexokinase inhibitor to measure reactive oxygen species (ROS) in human acute myeloid leukemia cells

Biochem/physiol Actions

Lonidamine (LND) is an indazole derivative and is an anti-spermatogenic agent. It exhibits anti-tumor activity by sensitizing tumors to photodynamic, chemo-, radiotherapy, and hyperthermia. LND also interferes with energy metabolism by blocking glycolysis, adenosine diphosphate (ADP-), and uncoupler-stimulated respiration on various nicotinamide adenine dinucleotide (NAD-) and flavin adenine dinucleotide (FAD)-linked substrates, hexokinase activity, and oxygen uptake in Ehrlich ascites tumor cells. It blocks lactate export and pyruvate uptake into the mitochondria by inhibiting proton-linked monocarboxylate transporter (MCT) and mitochondrial pyruvate carrier (MPC), respectively.
Inhibits the energy metabolism of neoplastic cells by interfering with hexokinase and disrupting uncoupler-stimulated mitochondrial electron transport; damages cell and mitochondrial membranes.

The endocannabinoid system represents an integrated neuronal network involved in the control of several organisms' functions, such as feeding behavior. A series of hybrids of 5-(4-chlorophenyl)-1-(2,4-dichloro-phenyl)-4-methyl-N-(piperidin-1-yl)-1H-pyrazole-3-carboxamide (mimonabant), a well-known inverse agonist of the type-1 cannabinoid receptor (CB1), once used as

Arsenic trioxide (ATO, Trisenox) is an important antileukemic drug, but its efficacy is frequently low when used as a single agent. Here, we demonstrate that the apoptotic action of ATO is greatly increased when combined with subcytotoxic curcumin concentrations in

Multi-drug resistant (MDR) cancer is a significant clinical obstacle and is often implicated in cases of recurrent, nonresponsive disease. Targeted nanoparticles were made by synthesizing a poly(D,L-lactide-co-glycolide)/poly(ethylene glycol)/epidermal growth factor receptor targeting peptide (PLGA/PEG/EGFR-peptide) construct for incorporation in poly(epsilon-caprolactone) (PCL)

Lonidamine is a safe, clinically useful anti-tumor drug, but its efficacy is generally low when used in monotherapy. We here demonstrate that lonidamine efficaciously cooperates with the anti-leukemic agent arsenic trioxide (ATO, Trisenox) to induce apoptosis in HL-60 and other

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.
