Peptides Related to Neuropeptide Y#
Neuropeptide Y is unique as an endogenous neuropeptide with well-characterized receptor pharmacology and a direct connection to human stress resilience. Its anxiolytic and stress-buffering properties distinguish it from most other neuropeptides. The following comparisons examine peptides with related applications in anxiety and stress.
Selank#
Selank is a synthetic tuftsin analog approved in Russia for anxiety. Both have anxiolytic properties but through entirely different mechanisms. NPY acts on Y1 receptors in the amygdala while selank modulates GABAergic signaling. NPY has the unique advantage of being directly linked to stress resilience in human studies, while selank has the advantage of clinical approval.
Semax#
Semax is an ACTH analog approved in Russia for cognitive enhancement. Both are administered intranasally for CNS effects, but their targets and applications differ substantially. NPY focuses on anxiety and stress, while semax is primarily nootropic and neuroprotective.
DSIP#
DSIP (delta sleep-inducing peptide) is an endogenous neuropeptide involved in sleep and stress adaptation. Both are natural brain peptides with stress-modulatory properties, but NPY has far more extensive receptor pharmacology, clinical data, and mechanistic understanding.
