Product description
PE-22-28 Peptide is a TREK-1 inhibitor with an IC50 value of 0.12 nM. PE 22-28 is also a 7-amino acid peptide, used as the core sequence for preparing analogs through chemical modification and amino acid substitution. PE 22-28 could be used in research on depression.
Neuroprotection and Repair
PE-22-28 exhibited significant neuroprotective effects in a rodent ischemia model:
Reduced β-cell apoptosis and death
Alleviated stroke-induced motor and cognitive deficits
Improved cognitive function
Studies have shown that PE-22-28 can enhance cognitive abilities through:
Promoting hippocampal neurogenesis, enhancing learning and memory function
Increasing synaptic connection formation, improving neural plasticity
Potential applications in research on neurodegenerative diseases such as Alzheimer's disease, as it increases CREB activity, which is typically downregulated in Alzheimer's disease
Other potential applications
Muscle function research: Trek-1 blockade increases muscle contractility, while activation promotes muscle relaxation, potentially useful in research on diseases such as myogenic bladder dysfunction.

PE-22-28 demonstrated rapid antidepressant effects in a mouse model of depression (within just 4 days), significantly outperforming traditional antidepressants with minimal side effects. Its mechanisms of action include: rapid induction of hippocampal neurogenesis (much faster than existing antidepressants); increased firing rate of 5-Hydroxytryptamine neurons; and enhanced CREB (cAMP response element-binding protein) activity, promoting synapse formation.
Key advantages and features of PE-22-28 Peptide
High selectivity: Highly specific for TREK-1 channels, without affecting other two-pore potassium channels such as TREK-2, TRAAK, TASK, and TRESK.
Improved stability: More stable than natural spadin, with a longer half-life, suitable for experimental applications.
Good safety profile: No significant side effects were observed in animal studies; it does not enhance seizures and instead exhibits neuroprotective effects.
Rapid onset of action: Significant effects were observed in depression and neurogenesis models in just 4 days, far exceeding traditional antidepressant products.

FAQ
01. What is PE-22-28 Peptide?
PE-22-28 is a short synthetic peptide with the sequence GVSWGLR. It is a fragment of the naturally occurring brain-derived neurotrophic factor spadin and is the smallest known fragment that effectively inhibits the activity of TREK-1 channels.
02. What is the mechanism of action of PE-22-28 Peptide?
The main mechanism of action of PE-22-28 is as a specific blocker of TREK-1 potassium channels. TREK-1 channels are expressed in the brain (particularly in areas that regulate mood, memory, and learning, such as the prefrontal cortex and hippocampus) and are typically involved in the regulation of depressive mood by reducing neuronal excitability. By blocking these channels, PE-22-28 increases neuronal excitability, promoting neurogenesis (the generation of new neurons) and synapsis (the formation of new synaptic connections), thereby producing an antidepressant effect.
03. What are the known side effects or safety concerns of PE-22-28 Peptide?
Because PE-22-28 Peptide is still in the investigational stage, its full spectrum of side effects in humans is not yet known. It is generally considered safe in research settings, but its use in uncontrolled environments may pose risks. Always consult a medical professional before using any unapproved substance.
