Acetyl-L-carnitine (O-Acetyl-L-carnitine; ALCAR) is an orally active mitochondrial energy metabolism regulator and neuroprotectant that can penetrate the blood-brain barrier. Acetyl-L-carnitine selectively enters cells and the brain through the organic cation transporter OCTN2. Acetyl-L-carnitine can participate in fatty acid β-oxidation, promote acetylcholine synthesis, regulate mitochondrial function and inhibit oxidative stress as an acetyl donor. Acetyl-L-carnitine exerts its activity by enhancing energy metabolism, protecting neurons and improving synaptic plasticity. Acetyl-L-carnitine is mainly used in the study of neurodegenerative diseases and metabolic disorder-related diseases such as neonatal hypoxic-ischemic brain damage, Alzheimer's disease, and depression.

In Vitro

Cell Viability and Apoptosis:
Acetyl-L-carnitine (1 mM; 30 min) significantly inhibits 1 μg/mL Doxycycline (HY-N0565)-induced caspase-3/9 activation, reduces reactive oxygen species (ROS) generation and apoptosis, and maintains glutathione levels in thioredoxin TRX2-deficient DT40 cells^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay^[1]

Cell Line:

TRX2^-/- DT40 cells (chicken B-cell line)
Concentration:

1 mM
Incubation Time:

30 min pretreatment before 1 μg/mL Doxycycline induction
Result:

Reduced activation of caspase-3 and caspase-9, key markers of mitochondrial apoptosis pathway, compared to untreated cells.
Decrease 40% in intracellular ROS levels, indicating attenuation of oxidative stress.
Maintained glutathione levels in both cytosol and mitochondria, preventing redox imbalance caused by TRX2 deficiency.
Resulted 35% reduction in apoptotic cell population, confirming protective effects against mitochondrial-dependent apoptosis.

In Vivo

Acetyl-L-carnitine (100 mg/kg; intraperitoneal injection; once daily; 14 days) significantly alleviates brain damage in the hypoxic-ischemic brain damage (HIBD) model of neonatal rats, improves neurological function, reduced oxidative stress levels, and decreases cell apoptosis^[2].
Acetyl-L-carnitine (300 mg/kg; oral gavage; once daily; 28 days) improves cognitive function in the cognitive impairment model of aged rats, enhances synaptic plasticity in the hippocampus, and increases the expression of brain-derived neurotrophic factor (BDNF)^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Neonatal Sprague-Dawley rats (male, 18-22g, postnatal day 7), hypoxic-ischemic brain damage (HIBD) model^[2]
Dosage:

100 mg/kg
Administration:

Intraperitoneal injection, once daily, for 14 consecutive days starting 24 hours after HIBD induction
Result:

Brain injury: Reduced infarct volume by 40% compared to the HIBD control group as measured by triphenyltetrazolium chloride (TTC) staining.
Neurological function: Improved neurological scores, including motor function, sensory function, and balance, as evaluated by a modified neurological severity score (mNSS).

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
