生物活性

α-Lipoic Acid is an antioxidant, which is an essential cofactor of mitochondrial enzyme complexes. α-Lipoic Acid inhibits NF-κB-dependent HIV-1 LTR activation^[1]^[2]^[3]. α-Lipoic Acid induces endoplasmic reticulum (ER) stress-mediated apoptosis in hepatoma cells^[4].

Mitochondrial bioenergetics

体外研究
(In Vitro)

The long terminal repeat (LTR) of HIV-1 is the target of cellular transcription factors such as NF-κB, and serves as the promoter-enhancer for the viral genome when integrated in host DNA^[1]. α-Lipoic Acid (Alpha-Lipoic acid, ALA), a naturally occurring dithiol compound, plays an essential role in mitochondrial bioenergetics. α-Lipoic Acid reduces lipid accumulation in the liver by regulating the transcriptional factors SREBP-1, FoxO1, and Nrf2, and their downstream lipogenic targets via the activation of the SIRT1/LKB1/AMPK pathway. Treatment of cells with α-Lipoic Acid (250, 500 and 1000 μM) significantly increases the NAD⁺/NADH ratio in HepG2 cells (P<0.05 or P<0.01). Treatment with α-Lipoic Acid (50, 125, 250 and 500 μM) increases SIRT1 activity in HepG2 cells. α-Lipoic Acid (50, 125, 250, 500 and 1000 μM) increases phosphorylation of AMPK and acetyl-CoA carboxylase (ACC) in HepG2 cells in a dose-dependent fashion^[1].

体内研究
(In Vivo)

C57BL/6J mice, divided into four groups, are fed an high-fat diet (HFD) for 24 weeks to induce nonalcoholic fatty liver disease (NAFLD) followed by daily administration of α-Lipoic Acid. Then, the effects of α-Lipoic Acid on hepatic lipid accumulation in long-term HFD-fed mice are assessed. Administration of α-Lipoic Acid (100 mg/kg or 200 mg/kg) markedly reduces visceral fat mass in mice. In addition, α-Lipoic Acid (100 mg/kg or 200 mg/kg) treatment inhibits the appetite and causes a dramatic weight loss (all P<0.05)^[1].

体外研究
(In Vitro)

Lipoic acid ((R)-(+)-α-Lipoic acid) is the form biosynthesized in humans which is essential for aerobic metabolism. Lipoic acid ((R)-(+)-α-Lipoic acid) is the nutritionally and therapeutically preferred form due to its “vitamin-like” role in metabolism. Lipoic acid ((R)-(+)-α-Lipoic acid) and S-(-)-α-Lipoic acid) constitute the racemic mixture Lipoic acid. Only the Lipoic acid ((R)-(+)-α-Lipoic acid) exists in nature and is an essential cofactor of four mitochondrial enzyme complexes. Lipoic acid ((R)-(+)-α-Lipoic acid) has been suggested to be nutritionally and therapeutically preferred form as antioxidant^[1].

Synonym: Aminooxy PEG Lipoic acid, Oxyamine PEG Lipoic acid, Hydroxyamine PEG Lipoic acid, Lipoic acid-PEG-ONH2.

Description:

Lipoic acid PEG Aminooxy (Lipoic acid-PEG-ONH2) is one of Nanocs carbonyl reactive PEG derivatives that have a lipoic acid group on one end of PEG and an aminooxy group (-ONH2) on the other terminus. Lipoic acid, also known as thioctic acid, contains a disufide bond that can bind to gold and other metal surface. It is also an important molecule parting in various biological processes. Aminooxy group (-ONH2), on the other hand, can react with aldehyde or ketone groups derived from polysaccarides or glycoproteins. Reaction between aminooxy and ketone group results in a stable oxime linkage, which is more stable than the schiff base formed between amine and ketone group.

Product Specification:

Form: Solid powder or semi-solid depends on PEG length
Color: Yellow to pale yellow
Reactive group: Aminooxy (-ONH2)
Reactive to: Aldehyde/ketone
Solubility: Soluble in water

Storage Conditions:
