“…В процессе исследований взгляды на роль АЛК претерпевали значительные изменения. Если первоначально АЛК рассматривалась лишь в качестве незаменимого кофактора для митохондриальных ферментов, то с открытия ее антиоксидантного действия и до настоящего времени АЛК признается сильным антиоксидантом [3,19]. Большинство последующих исследований АЛК сосредоточено именно на изучении ее антиоксидантных свой ств.…”

Alpha lipoic acid (ALA) is an essential cofactor for mitochondrial enzymes, a powerful antioxidant, and an important component of many metabolic processes. Most research on ALA has focused specifically on its antioxidant properties. A number of conditions – aging, atherosclerosis, liver cirrhosis, diabetes mellitus, various types of polyneuropathy, psoriasis and others can significantly reduce the level of ALA in the body. The article analyzes modern literature (107 sources, including 17 systematic reviews and meta-analyses). Traditionally, ALA is used in complex therapy of patients suffering from diabetic and alcoholic polyneuropathy. However, the analysis of studies conducted around the world is not limited to these two nosological forms. The use of ALA as adjuvant therapy for a number of conditions and diseases is justified, as confirmed by clinical studies, systematic reviews and meta-analyses. All studies assessed not only the effectiveness of ALC, but also its safety and the incidence of adverse events and showed that ALC has a high safety profile. ALA has not only a pronounced antioxidant effect, but also the ability to chelate toxic metals, increase intracellular glutathione levels, reduce blood glucose levels, overcome insulin resistance, participate in mitochondrial metabolism, stimulate the production of cAMP, normalize the lipid profile, reduce the level of inflammatory markers, etc. Based on Because of the positive effect of using ALC in the treatment of various symptoms and nosologies, the list of indications requires revision, expansion and addition.

“…To date, the extent to which each enantiomer contributes to α-lipoic acid pharmacological and toxicological effects is not fully understood. While it was proposed that S(-)-α-lipoic acid does not exhibit significant biological side effects [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ], some studies indicated that it could potentially hinder the activity of the R(-)-enantiomer [ 8 , 9 , 10 ].…”

“…Structurally, it comprises three components: a five-atom dithiolate ring, an alkyl chain, and a terminal carboxylic acid (see Figure 1). The chiral centre at position C6 results in two enantiomers, R(+)-α-lipoic acid, the naturally available form, and S(-)-α-lipoic acid, which can be synthetically obtained [1]. R(+)-α-lipoic acid is generally recognized to exhibit superior activity compared to S(-)α-lipoic acid [2][3][4][5][6], even as α-lipoic acid is usually marketed as a racemic mixture containing both enantiomers.…”

α-lipoic acid is a naturally occurring compound with potent antioxidant properties that helps protect cells and tissues from oxidative stress. Its incorporation into nanoplatforms can affect factors like bioavailability, stability, reactivity, and targeted delivery. Nanoformulations of α-lipoic acid can significantly enhance its solubility and absorption, making it more bioavailable. While α-lipoic acid can be prone to degradation in its free form, encapsulation within nanoparticles ensures its stability over time, and its release in a controlled and sustained manner to the targeted tissues and cells. In addition, α-lipoic acid can be combined with other compounds, such as other antioxidants, drugs, or nanomaterials, to create synergistic effects that enhance their overall therapeutic benefits or hinder their potential cytotoxicity. This review outlines the advantages and drawbacks associated with the use of α-lipoic acid, as well as various nanotechnological approaches employed to enhance its therapeutic effectiveness, whether alone or in combination with other bioactive agents. Furthermore, it describes the engineering of α-lipoic acid to produce poly(α-lipoic acid) nanoparticles, which hold promise as an effective drug delivery system.
