What is Selank used for?

Selank is a synthetic anxiolytic neuropeptide compound that targets the human central nervous system. It simulates the regulatory function of natural neuroprotective hormones in the human body, effectively activating neural regulation pathways to stabilize emotional state, relieve mental stress and assist in improving sub-health neurological conditions.

What does Selank do to your body?

Selank is a potent neuro-modulatory active peptide. It mainly acts on the central nervous system by regulating the secretion of neurotransmitters, stabilizing nerve excitability and relieving persistent mental anxiety and irritability. It effectively alleviates nervous tension, improves distracted attention and mental fatigue, and optimizes human mental and neural circadian state. In addition, it regulates neuroendocrine levels, enhances mental resilience, and delivers dual regulatory effects on emotional soothing and neural function optimization.

What effect can you get with Selank?

Experimental research shows that continuous standardized use of Selank can effectively stabilize emotional state, relieve chronic anxiety and mental stress in a short cycle. It significantly improves poor mental state, inattention and mood swings caused by neurological imbalance, repairs sub-health state of the nervous system, and provides a safer and more natural neural adjustment effect compared with traditional nerve soothing products.

——Product Description ——

Selank exhibits outstanding efficacy in emotional regulation, nervous system soothing and mental state adjustment compared with common neuro-regulating ingredients. As a high-activity synthetic neural peptide, Selank has high binding affinity for central nervous system receptors. This unique neuroregulatory mechanism enables it to effectively relieve anxiety and mental tension without causing neurological dependence or drowsiness. Relevant pharmacological studies confirm that Selank perfectly mimics the physiological activity of natural neuro-stabilizing substances, safely and efficiently regulating emotional and neurological balance. It is widely used in neuroscience research and mental physiology research, providing a safe and natural alternative to traditional nerve soothing adjustment methods.

ECHEMI Editorial Reference

Selank is a synthetic derivative of the tetrapeptide tuftsin that contains a proline-glycine-proline sequence at the C-terminus and has anxiolytic and anti-inflammatory activities. It increases the amplitude and discharge rate of inhibitory postsynaptic currents of neurons in the rat hippocampal CA1 region when used at a concentration of 1 μM. It decreases the level of affective responses and the number of erroneous escape attempts in rats in an acute stress situation, increases orientational-investigative responses of rats in an unfamiliar situation, and reduces the time mice spend immobile in the forced swim test. It increases locomotor activity of high-anxiety Balb/c, but not C57Bl/6, mice in the open field test. Selank (0.01 mg/kg) decreases verticalization induced by apomorphine in mice. It also decreases expression of the inflammation-related genesIl2rgandXcr1in mouse spleen after 90 minutes when administered at a dose of 100 μg/kg.
SELANK Synthetic is a single, non-glycosylated polypeptide chain containing 7 amino acids, having a molecular mass of 751.89 Dalton and a Molecular formula of C33H57N11O9.

Research

Class:
Mitochondria-targeted tetrapeptide (Szeto-Schiller peptide)

Status:
FDA-approved (Forzinity) — Accelerated Approval 2025

Mechanism:
A cell-permeable, synthetic tetrapeptide (D-Arg-Dmt-Lys-Phe-NH₂) that selectively concentrates in the inner mitochondrial membrane and reversibly binds to cardiolipin, a phospholipid essential for electron transport chain (ETC) function. By stabilizing cardiolipin, SS-31 restores mitochondrial bioenergetics, reduces cytochrome c peroxidase activity, and prevents oxidative damage in cells with impaired mitochondrial function.

Activity note:
SS-31 does not act via traditional receptor agonism. It binds cardiolipin with high selectivity in the inner mitochondrial membrane. Functional EC₅₀ values are context-dependent (cell type, stress model). Key electrophysiology studies report mitochondrial membrane potential restoration at nanomolar concentrations.
