Lonidamine (AF 1890, Diclondazolic Acid) is an orally bioactive small molecule inhibitor of hexokinase, also inhibits mitochondrial pyruvate carrier (Ki 2.5 μM in isolated rat liver mitochondria) and plasma membrane monocarboxylate transporters. Lonidamine reduces the oxygen consumption in both normal and neoplastic cells, while it increases the aerobic glycolysis of normal cells but inhibited that of tumor cells. Lonidamine induces the permeabilization of ANT proteoliposomes in a cell-free system, yet has no effect on protein-free liposomes. Lonidamine adds to synthetic planar lipid bilayers containing ANT, eliciting ANT channel activities with clearly distinct conductance levels. Lonidamine provokes a disruption of the mitochondrial transmembrane potential which precedes signs of nuclear apoptosis and cytolysis.
| ln Vitro |
In AKR-2B and TIG-1 cells, lonsidine (100 μM, 24 h) suppresses the rate of oxygen consumption and lactate generation induced by TGF-β[3]. Lonidamine (100 μM, 24/48 h) suppresses the growth of A549 and H2030BrM3 cells[4]. A549 and H2030BrM3 cell invasion is inhibited by lonsidamine (100–200 μM, 24 h)[4]. Inhibiting the activities of mitochondrial complex I and II, lonsidamine (100-1000 μM, 24 h) is used[4]. In H2030BrM3 lung cancer cells, lonsidamine (200 μM, 24 h) enhances ROS generation[4].

| ln Vivo |
In a mouse model of BLM-induced pulmonary fibrosis, lonsamine (oral treatment, 10-100 mg/kg/day, d10 to d20) enhances lung function by blocking hexokinase 2 (HK2) activity[3].
|
| Animal Protocol |
Animal/Disease Models: Lonidamine (oral administration, 10 -100 mg/kg/day, d10 to d20) improves lung function by inhibiting hexokinase 2 (HK2) activity in BLM-induced pulmonary fibrosis murine model[3].
Doses: 10, 30, 100 mg/kg/day Route of Administration: Oral administration, daily, d10 to d20 after BLM treatment. Experimental Results: Partially or completely reversed the increases in HK2 and lactate induced by BLM and decreased the expression of 10 profibrotic mediators. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (6.48 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (6.48 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
