| Description | L-Lactic acid ((S)-2-Hydroxypropanoic acid) is a natural product produced by the anaerobic glycolysis of pyruvic acid. L-Lactic acid is a sensitive indicator of tissue hypoxia and can be used as a hemodynamic indicator in critically ill patients. |
| Targets & IC50 | LDHA:3 nM |
| In vitro | METHODS: Mouse CD4+CD25-T cells were treated with low-glucose medium containing L-Lactic acid (5-20 mM), and Teff proliferation was detected by Flow cytometry. RESULTS: L-Lactic acid had a sustained inhibitory effect on T cell proliferation, and apoptosis-independent effect. [1] METHODS: T cells were cultured in medium containing L-Lactic acid (20 mM), and ROS levels were measured using ROS and superoxide detection assay kits. RESULTS: A significant reduction in ROS and O2- production was observed in L-Lactic acid-treated T cells. [2] |
| In vivo | METHODS: To study its effect on swimming endurance, L-Lactic acid (25-50 mg/kg in 0.9% NaCl) was administered intraperitoneally to ICR mice. RESULTS: L-Lactic acid enhanced the swimming endurance of mice, and the effect was dose-dependent. [3] METHODS: To investigate the effect on endotoxemia, L-Lactic acid (80 mg/kg) was intraperitoneally injected into mice, and 20 h later, a lethal dose of LPS (25 mg/kg) was intraperitoneally injected into mice to induce infectious shock. RESULTS: L-Lactic acid significantly inhibited LPS-induced cytokine induction in mice following endotoxemia.L-Lactic acid treatment decreased glucose uptake and lactate output during LPS stimulation.

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 µL Tween 80 and mix well until fully clarified.
3) Add 450 µL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
