説明
Noopept is the brand name for N-phenylacetyl-L-prolylglycine ethyl ester , a synthetic nootropic molecule. It has a similar effect to piracetam, in that it provides a mild cognitive boost after supplementation. It also provides a subtle psychostimulatory effect. Noopept is up to 1000-times more potent than the original racetam, Piracetam.
化学的特性
Noopept is a synthetic nootropic molecule grouped in the racetam class but structurally different from racetams.It is primarily water-soluble nootropic, but won't easily dissolve in water or juice. So it may help if you take it with a meal containing healthy fats.
来歴
Noopept (previously GVS-111) is a nootropic developed at the Zakusov Institute of Pharmacology (Russian Academy of Medical Sciences) by T. A. Gudasheva. It is one of several nootropics developed based on the structure of piracetam. Its advantage over piracetam is that it can be taken at a lower dose.
Noopept is a popular cognitive-enhancing supplement in the nootropic community. Proposed mechanism of actions based on preclinical studies include increasing acetylcholine signaling, increasing the expression of BDNF and NGF, protecting from glutamate toxicity, and increasing inhibitory neurotransmission in the brain.

使用
Noopept is a well-known nootropic that is often suggested as a first nootropic.Noopept is over 500 times more potentthan Piracetam.Like piracetam,it is capable of enhancing memory,learning,andfocus. Noopept is also a powerful antioxidant that prevents neurological disorders andhelps the brain grow.Because of this, it is thought to improve long-term memory. The human studies have shown promising results, with potential application in the treatment of Alzheimer's disease.
作用機序
Noopept is believed to amplify acetylcholine activity in the body. The reason this is noteworthy is that acetylcholine is known as the "learning transmitter" due to its impact on learning. It’s also involved in memory, cognition, and the mind-muscle connection. Noopept has also been shown to upregulate the expression of both NGF and BDNF, two important brain proteins that impact cognition and memory. Animal models also indicate that noopept modulates both the AMPA and NMDA receptors, helping to prevent glutamate toxicity, while also enhancing neuroplasticity. Noopept is also known as a powerful neuroprotectant due to its anti-inflammatory and antioxidant properties.
副作用
Noopept is associated with some mild side effects based on limited clinical evidence. possible side effects of noopept included sleep disturbances (5/31 patients), irritability (3/31), and increased blood pressure (7/31) (Neznamov and Teleshova, 2009).
製造方法
Noopept (ethyl ester of N-phenylacetyl-L-prolylglycine) was designed as a drug at State Zakusov Institute of Pharmacology. The synthesis of the drug is based on the original hypothesis of peptide design, according to which structures similar to known psychotropic agents are reproduced using appropriate amino acids. The non-peptide prototype of Noopept is the nootropic drug Piracetam.
1. Perform the carboxylation of N-phenylacetyl-L-proline and ethyl glycine in the presence of isobutyl chloroformate.
2. Add slowly isobutyl chloroformate (1.17 g, 8.6 mmol) to a solution of N-phenylacetyl-L-proline (2.0 g, 8.6 mmol) dissolved in a mixed solvent of THF and dichloromethane (1:1; THF/dichloromethane (v/v)).3.Stir the mixture for 4 h at 0 ～5 °C
