Noopept ≥99% – Pure substance

Noopept

Noopept is a synthetic dipeptide compound belonging to the class of nootropic substances studied in the biomedical sciences. Structurally it is the ethyl ester of N-phenylacetyl-L-prolylglycine — combining a phenylacetyl residue with a proline–glycine dipeptide. The molecule is sometimes described as a derivative designed for increased lipophilicity relative to the racetam scaffold, although chemically it represents a distinct dipeptide class. Owing to its well-defined structure and high activity in laboratory models, it is a frequent subject of in vitro neuropharmacological research.

Physicochemical data

Characteristics and research applications

Noopept contains a stereocentre in the pyrrolidine ring derived from L-proline, making it an optically active compound and a relevant reference point in enantiomeric purity analysis. The presence of ester and amide bonds governs its characteristic reactivity — the ester group is susceptible to hydrolysis in aqueous and enzymatic environments, so the compound is used as a model in studies of peptidomimetic stability and hydrolysis kinetics.

In analytical laboratories Noopept serves as a reference standard in liquid chromatography (HPLC, UPLC) coupled with UV detection and mass spectrometry, where its well-defined molecular mass and characteristic fragmentation facilitate identification and quantification. The material is used in the development and validation of analytical methods, quality control, and studies of dipeptide metabolism.

In neurobiology and experimental pharmacology, Noopept is the subject of work on mechanisms of synaptic plasticity, neurotrophic activity, and signalling pathways in cell cultures and animal models. It is employed as a tool for investigating peptidergic regulatory systems and in structure–activity relationship studies within peptidomimetic compounds. All applications are strictly research and laboratory in nature; this description contains no health recommendations or dosage information.

Because of the ester bond, storage in a tightly closed container at low temperature, away from moisture and light, is recommended to limit the risk of hydrolysis. Personal protective equipment should be used at all times in accordance with good laboratory practice.
