What is the N-Acetyl Selank peptide?

N-Acetyl Selank is an acetylated form of the Selank peptide. The acetylation of the peptide into N-Acetyl Selank improves its stability. Selank is a synthetic analogue of the natural human tetrapeptide Tuftsin. Tuftsin is an immunomodulatory peptide, and N-Acetyl Selank appears to possess many of its effects. In addition, N-acetyl Selank also appears to exhibit effects on neurotransmitters, brain signaling, and neuroplasticity.

N-Acetyl Selank Research

N-Acetyl Selank as a nootropic
N-Acetyl Selank may have similar effects as Selank, but with the potential for increased efficacy and stability.
In research studies with rat subjects, scientists show that the peptide appears to activate the serotonin metabolism in the tested animals’ brains.[1] As a result, administering Selank appeared to enhance memory storage processes as compared to placebo.

N-Acetyl Selank and anxiolytic effects
The anxiolytic effects of Selank have been studied experimentally. In laboratory research, Selank was posited to increase the levels of calming neurotransmitters such as serotonin in the brains of rats.[2] Serotonin is a primary target of most anxiolytics, and blocking its reuptake is a common mechanism of action for these medications.

N-Acetyl Selank and Neuroplasticity
N-Acetyl Selank may upregulate the brain-derived neurotrophic factor (BDNF) levels in the central nervous system. Animal studies show that administration of Selank can increase BDNF levels in the hippocampus.[3]
BDNF is a growth factor in the brain that supports neurons’ growth and adaptation.[4] According to scientists, BDNF may also induce remodeling in the nerve tissue and the formation of new connections.[5]
BDNF may also stimulate neurogenesis, which is the formation of new neurons in parts of the adult brain that still retain stem cells.[6] Therefore, Selank may have protective effects on the brain and stimulate neural plasticity.
