Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	NF-κB ^[2] LTR ^[1] LTR ^[2]
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].
