Description
Selank is a synthetic tuftsin analog studied in controlled laboratory environments for its interaction with GABAergic signaling pathways and neuroimmune communication models.
Chemical Information
- Chemical Name: Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro; tuftsin heptapeptide analog)
- Also Known As: TP-7; Selanc
- Compound Class: Synthetic tuftsin-derived heptapeptide; multi-target CNS neuromodulator
- Sequence: Thr-Lys-Pro-Arg-Pro-Gly-Pro
- Molecular Formula: C33H57N11O9
- Molecular Weight: 751.9 g/mol
- CAS Number: 129954-34-3
- Origin: Developed at the Institute of Molecular Genetics, Russian Academy of Sciences, by extending the tuftsin tetrapeptide (Thr-Lys-Pro-Arg) with a C-terminal Pro-Gly-Pro sequence for enhanced metabolic stability
Applications
- GABA-A receptor positive allosteric modulation studies. Selank provides a mechanistic profile distinct from benzodiazepines; it modulates GABAergic gene expression in ways that benzodiazepines do not replicate, including blocking the modulatory activity of diazepam and olanzapine in receptor expression studies, making it a pharmacological tool for dissecting receptor subunit dynamics
- Enkephalin metabolism research. Selank is studied as a pharmacological tool for examining the consequences of extending enkephalin synaptic lifetime without direct opioid receptor agonism; experiments pair Selank with naloxone controls to confirm enkephalin-mediated effects
- Comparative gene expression studies. The 84-gene neurotransmission panel used by Volkova et al. has become a reference design for examining Selank’s broad genomic footprint. The same panel distinguishes Selank-specific gene regulation patterns from those of direct GABA agonists
- Neuroimmune intersection research. Selank retains tuftsin’s immunomodulatory properties, including documented modulation of 34 of 84 inflammation-related genes in mouse spleen (Uchakina et al. 2008), interleukin-6 effects, and selective interferon-alpha induction without affecting IL-4, IL-10, or TNF-alpha. This dual CNS/immune profile supports use in models examining neuroimmune signaling
- BDNF expression research in hippocampal models under stress conditions. Selank upregulates hippocampal BDNF mRNA in stressed rodent models where BDNF is otherwise suppressed; this is mechanistically adjacent to but distinct from Semax’s BDNF upregulation route, which operates through melanocortin receptor interaction rather than enkephalinergic stabilization
Storage and Handling
Store lyophilized powder at -20C for long-term stability, or at 2-8C for short-term use. Protect from heat, moisture, and direct light. The Pro-Gly-Pro C-terminal extension confers resistance to carboxypeptidase degradation, improving stability relative to the parent tuftsin sequence, though storage conditions remain important for long-term integrity. Reconstituted solutions should be stored at 2-8C and used promptly. Avoid repeated freeze-thaw cycles.
Compliance Notice
