Perinatal hypoxia ischemia (HI) is a significant cause of brain injury in surviving infants. Although hypothermia improves outcomes in some infants, additional therapies are needed since about 40% of infants still have a poor outcome. Acetyl-L-carnitine (ALCAR), an acetylated derivative of L-carnitine, protected against early changes in brain metabolites and mitochondrial function after HI on postnatal day (PND) 7 in a rat pup model of near-term HI injury. However, its efficacy in long-term structural and functional outcomes remains unexplored...

Parkinson's disease (PD) is a movement disorder and the second most common neurodegenerative disease worldwide in which nigrostriatal dopaminergic neurons within substantia nigra pars compacta (SNC) are lost, with clinical motor and non-motor symptoms including bradykinesia, resting tremor, rigidity, stooping posture and cognitive deficits. This study was undertaken to evaluate the neuroprotective potential of acetyl-l-carnitine (ALC) against unilateral striatal 6-hydroxydopamine (6-OHDA)-induced model of PD and to explore some involved mechanisms...

Peripheral nerve injury is a widespread and disabling condition that can impair the individual's daily life. Studies involving medications that may positively affect peripheral nerve regeneration are rare. The aim of this study was to investigate new treatments after peripheral nerve injury using various neuroprotectants, melatonin, alcar and leptin, in the regenerative process in an experimental rat model. Wistar albino rats were randomly divided into eight groups containing equal number of animals. Intraperitoneal injection of melatonin (50mg/kg, for 21days), leptin (1mg/kg, for 21days) and acetyl-l-carnitine (50mg/kg, for six weeks) was performed postoperatively...

The present study aimed to evaluate the efficacy and safety of acetyl-L-carnitine (ALC) for the treatment of chemotherapy-induced peripheral neuropathy (CIPN). The study was carried out as a prospective, randomized, double-blind, placebo-controlled and paralleled clinical study. A total of 239 patients with CIPN were selected as the study subjects. Of the 239 subjects, 118 subjects received 3 g/day ALC orally for 8 weeks and 121 received a placebo. The primary endpoint was improvement of peripheral neuropathy by at least one grade...

Parkinson's disease is accompanied by nonmotor symptoms including cognitive impairment, which precede the onset of motor symptoms in patients and are regulated by dopamine (DA) receptors and the mesocorticolimbic pathway. The relative contribution of DA receptors and astrocytic glutamate transporter (GLT-1) in cognitive functions is largely unexplored. Similarly, whether microglia-derived increased immune response affects cognitive functions and neuronal survival is not yet understood. We have investigated the effect of acetyl-L-carnitine (ALCAR) on cognitive functions and its possible underlying mechanism of action in 6-hydroxydopamine (6-OHDA)-induced hemiparkinsonian rats...

The aim of this study was to investigate the effects of cisplatin and the protective role of acetyl l-carnitine against uterine tube toxicity. Twenty-four female Wistar albino rats were divided into four groups: control group was injected with saline (control); group 2 was injected with acetyl l-carnitine; group 3 was injected with cisplatin; and group 4 was pre-treated with acetyl l-carnitine before cisplatin intraperitoneal injection. According to our results, a significant weight loss was observed in rats from group 3...

Perfluorooctanoic acid (PFOA), a persistent organic pollutant, is associated with developmental toxicity. This study investigated the mechanism of PFOA-induced developmental cardiotoxicity in chicken embryo, focusing on the interactions between developmental exposure to PFOA and the levels of l-carnitine (LC), acetyl-l-carnitine (ALC) and propionyl-l-carnitine (PLC) in the heart. To evaluate the developmental cardiotoxicity, fertile chicken eggs were exposed to 0.1, 0.5, 1, 2 or 5mg/kg PFOA via air cell injection...

Males are more susceptible to brain mitochondrial bioenergetic dysfunction following neonatal cerebral hypoxic-ischemia (HI) than females. Mitochondrial biogenesis has been implicated in the cellular response to HI injury, but sex differences in biogenesis following HI have not been described. We tested the hypothesis that mitochondrial biogenesis or the expression of mitochondrial electron transport chain (ETC) proteins are differentially stimulated in the brains of 8 day old male and female rats one day following HI, and promoted by treatment with acetyl-L-carnitine (ALCAR)...

A novel aqueous solvent-based dispersive liquid-liquid microextraction (AS-DLLME) method was combined with narrow-bore liquid chromatography and fluorescence detection for the determination of hydrophilic compounds. A remover (non-polar solvent) and extractant (aqueous solution) were introduced into the derivatization system (acetonitrile) to obtain a water-in-oil emulsion state that increased the mass transfer of analytes. As a proof of concept, three quaternary ammonium substances, including butyrobetaine, l-carnitine and acetyl-l-carnitine, were also used as analytes and determined in pharmaceuticals, personal care products, food and human plasma...

Painful diabetic peripheral neuropathy occurs in approximately 25% of patients with diabetes mellitus who are treated in the office setting and significantly affects quality of life. It typically causes burning pain, paresthesias, and numbness in a stocking-glove pattern that progresses proximally from the feet and hands. Clinicians should carefully consider the patient's goals and functional status and potential adverse effects of medication when choosing a treatment for painful diabetic peripheral neuropathy...

Neuropathic pain (NP) is the result of a series of conditions caused by diseases or lesions to the somatosensory system. Due to the better understanding of NP pathophysiology previously unexplored therapies have been used with encouraging results. In this group, acetyl-L-carnitine, alpha-lipoic-acid, cannabinoids, clonidine, EMA401, botulinum toxin type A and new voltage-gated sodium channel blockers, can be included. Besides, changing paradigms may occur with the advent of optogenetics and a better understanding of epigenetic regulation...

Chondroitin sulfate proteoglycans (CSPGs) inhibit the formation of axon collateral branches. The regulation of the axonal cytoskeleton and mitochondria are important components of the mechanism of branching. Actin-dependent axonal plasticity, reflected in the dynamics of axonal actin patches and filopodia, is greatest along segments of the axon populated by mitochondria. It is reported that CSPGs partially depolarize the membrane potential of axonal mitochondria, which impairs the dynamics of the axonal actin cytoskeleton and decreases the formation and duration of axonal filopodia, the first steps in the mechanism of branching...

OBJECTIVE: Complementary medicines are readily available and becoming increasingly popular. Acetyl-l-carnitine (ALC) is widely recognised as a safe dietary supplement to aid weight loss. We present the case of a patient who had a relapse of mania in the context of ALC use for weight loss over a two week period, on the background of bipolar I disorder previously in remission. The patient's symptoms resolved a few days after ALC was ceased. CONCLUSIONS: Given the high rates of obesity among people with mental illness, it is possible ALC may be utilised in the hope of aiding weight loss...

OBJECTIVES: This was the first 12-week, open-label, uncontrolled trial aimed at exploring the efficacy of acetyl-L-carnitine (ALC) add-on pharmacotherapy on clinical symptoms and cognitive functioning in 15 schizophrenia patients with suboptimal clinical response despite receiving clozapine (CLZ) monotherapy at the highest tolerated dosage. METHODS: After clinical (Positive and Negative Symptoms Scale [PANSS]) and neuropsychological (Wisconsin Card Sorting Test, Stroop Color-Word Test, Verbal Fluency Test) assessments, patients received 1 g/d of ALC for 12 weeks...

Hypoxic circumstances result in functional and structural impairments of the brain. Oxygen-glucose deprivation (OGD) on hippocampal slices is a technique widely used to investigate the consequences of ischemic stroke and the potential neuroprotective effects of different drugs. Acetyl-l-carnitine (ALC) is a naturally occurring substance in the body, and it can therefore be administered safely even in relatively high doses. In previous experiments, ALC pretreatment proved to be effective against global hypoperfusion...

Although regulation of energy metabolism has been linked with multiple disorders, its role in depression and responsiveness to antidepressants is less known. We found that an epigenetic and energetic agent, acetyl-l-carnitine (LAC, oral administration), rapidly rescued the depressive- and central and systemic metabolic-like phenotype of LAC-deficient Flinders Sensitive Line rats (FSL). After acute stress during LAC treatment, a subset of FSL continued to respond to LAC (rFSL), whereas the other subset did not (nrFSL)...

The adult brain is capable of adapting to internal and external stressors by undergoing structural plasticity, and failure to be resilient and preserve normal structure and function is likely to contribute to depression and anxiety disorders. Although the hippocampus has provided the gateway for understanding stress effects on the brain, less is known about the amygdala, a key brain area involved in the neural circuitry of fear and anxiety. Here, in mice more vulnerable to stressors, we demonstrate structural plasticity within the medial and basolateral regions of the amygdala in response to prolonged 21-day chronic restraint stress (CRS)...

Increased male susceptibility to long-term cognitive deficits is well described in clinical and experimental studies of neonatal hypoxic-ischemic encephalopathy. While cell death signaling pathways are known to be sexually dimorphic, a sex-dependent pathophysiological mechanism preceding the majority of secondary cell death has yet to be described. Mitochondrial dysfunction contributes to cell death following cerebral hypoxic-ischemia (HI). Several lines of evidence suggest that there are sex differences in the mitochondrial metabolism of adult mammals...
