Alpha-lipoic acid has some neuroprotective properties, but this action has not been investigated in models of epilepsy. The aim of the present study was to investigate the protective efficacy of α-lipoic acid (lipoic acid) against pilocarpine-induced cell death through the caspase-dependent or -independent mitochondrial apoptotic pathways. Wistar rats were injected intraperitoneally with 0.9% saline (control group), pilocarpine (400 mg/kg, pilocarpine group) alone, or α-lipoic acid (20 mg/kg) in association with pilocarpine (400 mg/kg) 30 min before administration of α-lipoic acid. After the treatments all groups were observed for 24 h. Cell death was reduced in lipoic acid-treated rats. Cytosolic translocation of cytochrome c and subsequent activation of caspase-3 were reduced by lipoic acid treatment. AIF nuclear translocation and subsequent large-scale DNA fragmentation were also decreased in lipoic acid-treated rats. Our study suggests that lipoic acid inhibits both caspase-dependent and -independent apoptotic pathways and may be neuroprotective against hippocampal damage during pilocarpine-induced seizures.

Persistent oxidative stress following bone defects significantly impedes the repair of bone tissue. Designing an antioxidative hydrogel with a suitable mechanical strength can help alter the local microenvironment and promote bone defect healing. In this work, α-lipoic acid (LA), a natural antioxidant small molecule, was chemically cross-linked with lipoic acid-functionalized poly(ethylene glycol) (PEG, = 6k or 10k) in sodium bicarbonate solution, to prepare LA-PEG hydrogels (LP, = 6k or 10k).

This study aimed to investigate the protective effects of vitamin B complex and alpha-lipoic acid (ALA) pre-treatments on hepatic ischemia-reperfusion injury (IRI) in rats, focusing on their potential to enhance antioxidant defense mechanisms and reduce post-ischemic liver damage. Thirty male Wistar albino rats were divided into four groups: sham group (n = 10), IRI group (n = 10), vitamin B group (n = 10), vitamin B + ALA group (n = 10). In the IRI, vitamin B, and vitamin B + ALA groups, the rats underwent 45 min of hepatic ischemia followed by 60 min of reperfusion.

Inflammatory bowel disease involves excess reactive oxygen species (ROS) and hydrogen sulfide (HS) at inflammatory sites. Nanozyme-mediated ROS and HS scavenging therapy is promising for colitis treatment. Here, we synthesized a multiple ROS scavenging CuO nanoparticle and first explored its HS scavenging capacity.

Chitosan is a bio-based material that is more environmentally friendly than traditional petroleum-based materials, but its biofilms often suffer from brittleness and limited antioxidant and antibacterial properties. To overcome these challenges, chemically modified chitosan is a key solution. Herein, a novel CS-LA/CHA films were prepared through a radical reaction of chitosan (CS), lipoic acid/chalcone derivative (LA/CHA) and N,N-methylene bisacrylamide (MBA).

Oxidative stress, caused by an imbalance between the generation of reactive oxygen species (ROS) and the body's intrinsic antioxidant defenses, plays a critical role in neurodegenerative diseases such as Alzheimer's, Parkinson's, and Huntington's. Beyond these conditions, recent evidence indicates that dysregulated redox balance is implicated in neuropsychiatric disorders, including schizophrenia, major depressive disorder, and anxiety disorders. Preclinical and clinical studies have demonstrated the potential of antioxidants, such as N-acetylcysteine, sulforaphane, alpha-lipoic acid, L-carnitine, ascorbic acid, selenocompounds, flavones and zinc, in alleviating neuropsychiatric symptoms by mitigating excitotoxicity, enhancing synaptic plasticity, reducing microglial overactivation and promoting synaptogenesis.
