Selank and DSIP (Delta Sleep-Inducing Peptide) are neuroactive peptides investigated in neuroscience, neuroendocrine, and neurochemical research contexts involving central nervous system signaling, neurochemical signaling pathways, stress-response–associated frameworks, and circadian-related biological systems.
Although both compounds are studied within neuropeptide research, they differ in structural origin, signaling domains, and circadian signaling systems examined in experimental models.
Derived from tuftsin and studied in GABA-related and serotonin-associated neurochemical signaling pathways.
Associated with circadian and neuroendocrine signaling systems in rest-phase biological models.
