Neurotensin
Overview
Neurotensin is a 13-amino acid neuropeptide widely distributed in the central nervous system and gastrointestinal tract, where it modulates dopaminergic neurotransmission, nociception, and intestinal function. It acts primarily through the neurotensin receptor 1 (NTSR1), influencing mesolimbic and nigrostriatal pathways implicated in motivation, reward, and motor control. Neurotensin has been studied for its potential roles in schizophrenia, pain modulation, and cognitive function.
Key Research Findings
Preclinical studies have demonstrated that neurotensin receptor agonists can modulate dopamine release and influence behavioral models of psychosis and cognition, with publications in neuropsychopharmacology journals over the past three decades. Altered neurotensin levels have been observed in postmortem brain tissue from individuals with schizophrenia. No neurotensin-based therapeutics have reached clinical trials due to poor stability and CNS penetration of the native peptide.

Semax
FDA ApprovedA synthetic heptapeptide analog of the ACTH(4-7) fragment (Met-Glu-His-Phe-Pro-Gly-Pro) with nootropic and neuroprotective properties. Semax modulates BDNF and NGF expression, enhances monoaminergic neurotransmission, and provides neuroprotection through anti-oxidant and anti-inflammatory mechanisms. It crosses the blood-brain barrier via intranasal administration.
Selank
InvestigationalA synthetic analog of the endogenous tetrapeptide tuftsin (Thr-Lys-Pro-Arg) with an added Pro-Gly-Pro sequence for stability. Selank exhibits anxiolytic activity comparable to benzodiazepines without sedation, dependence, or withdrawal effects. It modulates the expression of BDNF, serotonin, dopamine, and norepinephrine, and influences IL-6 and GABA receptor expression.
Cerebrolysin
InvestigationalA porcine brain-derived peptide preparation consisting of low-molecular-weight neuropeptides and free amino acids that mimic the action of endogenous neurotrophic factors. Cerebrolysin exhibits neurotrophic activity similar to BDNF, GDNF, and CNTF, promoting neuronal survival, synaptic plasticity, and neurogenesis. It modulates GSK-3beta, CDK5, and calcineurin-NFAT signaling cascades involved in neurodegeneration.
P21 (Peptide)
Research PhaseA small synthetic peptide derived from the active region of ciliary neurotrophic factor (CNTF) designed to promote neurogenesis and synaptic plasticity. P21 is a tetrapeptide that crosses the blood-brain barrier and enhances dentate gyrus neurogenesis by increasing BDNF expression. Unlike full-length CNTF, P21 does not activate the JAK-STAT pathway or produce the anorectic and immunogenic effects of the parent protein.
