Noopept Research

What the evidence says
Mostly mechanism / observational
Most Noopept studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from medium-quality randomised trials published 2007–2023 with a typical study size of 60 participants.

Gudasheva TA et al. · Current pharmaceutical design (2018)
The latter usually corresponds to a beta-turn of some regulatory peptide.
The second approach represents the design of tripeptoide mimetic of the beta-turn of regulatory peptide or protein.
The results of the studies, which led to the discovery of endogenous prototypes of the known non-peptide drugs piracetam and sulpiride, are presented herein.
The results have demonstrated that noopept, used in dose 20 mg daily during 2 months, improves cognitive functions in stroke patients and has a high level of safety.
Amelin AV et al. · Zhurnal nevrologii i psikhiatrii imeni S.S. Korsakova (2011)
An analysis of MMSE scores and lateral and categorical associations revealed the significant improvement of cognitive functions after 2 months in patients of the main group compared to the controls.
Cognitive functions were assessed before and after treatment using neuropsychological tests.
The global assessment of efficacy revealed the mild improvement in the main group while no changes were found in the control group.

The EEG changes in posttraumatic brain lesion were less typical.
Bochkarev VK et al. · Zhurnal nevrologii i psikhiatrii imeni S.S. Korsakova (2008)
The analysis of frequency and spatial structure of EEG changes reveals that noopept exerts a nonspecific activation and anxyolytic effect.
The differences in EEG changes depending on the brain pathology were found.
The EEG indices of nootropic effect of the drug were most obvious in cerebral vascular diseases.
5Physical and psychological efficiency under changing environmental conditionsRCT2007
Therefore, all the drugs studied (vinpotropil, cortexin, noopept and dilept) can be recommended as the agents producing activation, support and recovery of the physical and psychological efficiency under rapidly changing environment conditions.
Shabanov PD et al. · Eksperimental'naia i klinicheskaia farmakologiia (2007)
Noopept, affecting positively a psychological component of the functional state, can be used for rapid adaptation to both cold and hot climate.
In the hot climate, noopept also enhanced the physical work capacity.
Therefore, all the drugs studied (vinpotropil, cortexin, noopept and dilept) can be recommended as the agents producing activation, support and recovery of the physical and psychological efficiency under rapidly changing environment conditions.
6Neuroprotective effect against Aβ-induced cellular damageObservationalCited 15×2014
Taken together, these data provide evidence that novel cognitive enhancer noopept protects PC12 cell against deleterious actions of Aβ through inhibiting the oxidative damage and calcium overload as well as suppressing the mitochondrial apoptotic pathway.
Ostrovskaya RU et al. · Journal of biomedical science (2014)
Taken together, these data provide evidence that novel cognitive enhancer noopept protects PC12 cell against deleterious actions of Aβ through inhibiting the oxidative damage and calcium overload as well as suppressing the mitochondrial apoptotic pathway.
Moreover, neuroprotective properties of noopept likely include its ability to decrease tau phosphorylation and to restore the altered morphology of PC12 cells.
Therefore, this nootropic dipeptide is able to positively affect not only common pathogenic pathways but also disease-specific mechanisms underlying Aβ-related pathology.
It was revealed that the effect of noopept is accompanied by changes in gene expression, which belong to different metabolic pathways and are controlled by the transcription factor HIF-1.
Zainullina LF et al. · Doklady. Biochemistry and biophysics (2020)
The effect of noopept (N-phenylacetyl-L-prolyl-glycine ethyl ester) on the DNA-binding activity of HIF-1 in SH-SH5Y cells and the mechanisms of stabilization of this transcription factor were studied in vitro.
Noopept was shown to increase both the basal DNA-binding activity of HIF-1 and the activity induced by various hypoxia mimetics.
The mechanism of stabilization of the oxygen-sensitive HIF1α subunit by noopept involves the inhibition of HIF-1 prolyl hydroxylase, which is indirectly indicated by the data obtained using the ODD-Luc reporter, and the positive effect on the level of the HIF1α protein.
These data suggest that Noopept does not stimulate cell growth.
Zainullina LF et al. · Bulletin of experimental biology and medicine (2019)
The previously established multifactorial mechanism of action of the drug includes enhancement of neurotrophin NGF and BDNF expression and increase in HIF-1 activity.
The possible mitogenic action of Noopept was estimated by its effect on cell proliferation.
Noopept did not affect cell distribution over G1, S, G2 cell cycle phases and the relative level of proliferation marker Ki-67 in the cell lines under study.
The treatment promoted functional normalization of vegetative nervous system and antioxidative systems, reduced manifestations of anxiety, decreased frequency of adverse neuro- and cardiotoxic responses to antituberculous drugs.
Mordyk AV et al. · Klinicheskaia meditsina (2009)
The study evaluated clinical efficiency of noopept used to prevent adverse side effects of antituberculous agents.
It included 60 patients with newly diagnosed respiratory tuberculosis.
Those in group 1 (n = 30) received 10 mg of noopept twice daily during the first month.
