この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。

6.250mg/ml (30.29mM) Taking the 1 mL working solution as an example, add 50 μL of 125 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 (+)-α-Lipoic acid ((R)-(+)-α-Lipoic acid, α-Lipoic acid, Alpha-Lipoic acid), a physiological form of thioctic acid, is a strong antioxidant that relieves diabetic neuropathic symptoms. It shows superior antioxidative effects to its racemate. R(+)-α-lipoic acid is an essential cofactor of mitochondrial enzyme complexes. R(+)-α-lipoic acid inhibits NF-κB-dependent HIV-1 LTR activation.
in vitro

Using L6 myotubes and 3T3-L1 adipocytes as a model of muscle and fat cells in culture, (+)-α-Lipoic acid (R-LA) is shown to increase tyrosine phosphorylation of insulin receptor and IRS-1, to enhance PI 3-kinase and Akt1 activities, to elevate GLUT4 content in the plasma membranes, and to increase glucose uptake into the cells. 3T3-L1 adipocytes possess a low capacity to reduce this compound and the oxidized isoforms are effective in stimulating glucose transport. This chemical modulates glucose transport by changing intracellular redox status. Insulin receptor is a target of this compound action[1].

実験の流れ

Cells seeded in 12-well plates were incubated for 2–48 h with (+)-α-Lipoic acid (250 μM) and loaded with H2DCF-DA (20 μM) for the last 30 min in PBS containing this compound. For some experiments cells were washed and incubated with this chemical (0.25-1 μM) and H2DCF-DA (20 μM) for 30 min. Following the treatments, cells were gently scraped by a lifter and suspended in the same media. For detection of intracellular fluorescence, cells were excited using a 488-nm argon-ion laser in a flow cytometer. The dichlorofluorescein (DCF) emission was recorded at 530 nm. Data were collected from at least 20,000 cells.
