N-Phenylacetyl-L-prolylglycine ethyl ester

A synthetic nootropic compound

Chemical structure of Noopept

N-Phenylacetyl-L-prolylglycine ethyl ester is a synthetic nootropic compound that is often marketed under the brand name Noopept. It is a peptide-derived compound that is structurally related to the racetam family of nootropics, although it is not a racetam itself. Noopept is known for its potential cognitive-enhancing effects and is used by some individuals to improve memory, focus, and overall cognitive function.

Chemical Structure and Properties

Noopept is a dipeptide compound, meaning it is composed of two amino acids linked together. Its chemical structure includes a phenylacetyl group attached to a prolylglycine ethyl ester. The presence of the phenylacetyl group is thought to contribute to its ability to cross the blood-brain barrier, allowing it to exert its effects on the central nervous system.

Mechanism of Action

The exact mechanism of action of Noopept is not fully understood, but it is believed to enhance cognitive function through several pathways:

• Neuroprotection: Noopept is thought to have neuroprotective properties, potentially reducing oxidative stress and protecting neurons from damage.
• Cholinergic System: It may modulate the cholinergic system, enhancing the activity of acetylcholine, a neurotransmitter associated with learning and memory.
• Glutamatergic System: Noopept may influence the glutamatergic system, which is involved in synaptic plasticity and cognitive processes.
• Brain-Derived Neurotrophic Factor (BDNF): Some studies suggest that Noopept may increase the expression of BDNF, a protein that supports the survival and growth of neurons.

Uses and Benefits

Noopept is primarily used as a cognitive enhancer. Users report benefits such as improved memory, increased focus, and enhanced learning ability. It is also sometimes used to alleviate symptoms of anxiety and depression, although these effects are less well-documented.

Dosage and Administration

Noopept is typically administered orally, with common dosages ranging from 10 to 30 mg per day. It is often recommended to start with a lower dose to assess individual tolerance and response. Due to its potency, Noopept is usually taken in cycles, with breaks in between to prevent tolerance buildup.

Side Effects and Safety

While Noopept is generally considered safe when used at recommended dosages, some users may experience side effects such as headaches, irritability, or insomnia. It is important to use Noopept responsibly and consult with a healthcare professional if any adverse effects occur.

Legal Status

The legal status of Noopept varies by country. In some regions, it is available as a dietary supplement, while in others, it may be classified as a prescription medication or a controlled substance. Users should be aware of the regulations in their specific location before purchasing or using Noopept.
