产品介绍
α-Lipoic Acid (Thioctic acid) 是一种抗氧化剂,是线粒体酶复合物的重要辅助因子。α-Lipoic Acid 可抑制NF-κB依赖性的HIV-1LTR 活化。α-Lipoic Acid 诱导内质网应激 (ERS) 介导的肝癌细胞凋亡 (apoptosis)。α-Lipoic Acid 可与 CPUL1 (HY-151802) 合成自组装的纳米聚合体 CPUL1-LA NA,其抗肿瘤效果优于 CPUL1。
生物活性

α-Lipoic Acid (Thioctic acid) is an antioxidant, which is an essential cofactor ofmitochondrialenzyme complexes. α-Lipoic Acid inhibitsNF-κB-dependentHIV-1LTR activation[1][2][3]. α-Lipoic Acid induces endoplasmic reticulum (ER) stress-mediatedapoptosisin hepatoma cells[4]. α-Lipoic Acid can be used withCPUL1(HY-151802) to construct the self-assembled nanoaggregate CPUL1-LA NA, which has improved antitumor efficacy than CPUL1[5].

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].
