What is SP?
A tachykinin neuropeptide involved in nociception, inflammation, and gastrointestinal signaling. It is widely used in receptor pharmacology and pain-pathway research.
Key Benefits & Mechanisms
pain signaling research
neurogenic inflammation
gut motility research
Research Summary
Substance P is a canonical neuropeptide acting primarily at NK1 receptors and is strongly associated with pain transmission. It remains an important laboratory standard for studying neuroinflammation and sensory signaling.
Related Peptides
Neurokinin A
Neurokinin A
A tachykinin neuropeptide generated from the preprotachykinin A precursor. It participates in pain transmission, neurogenic inflammation, and smooth muscle signaling.
NeuropeptidesOXT
Oxytocin
A hypothalamic nonapeptide neuropeptide and hormone best known for roles in parturition, lactation, and social behavior. It is also used as a reference compound in receptor and intranasal-delivery research.
NeuropeptidesLEU-ENK
Leucine Enkephalin
An endogenous pentapeptide from the proenkephalin family that acts on opioid receptors. It is a classic opioid neuropeptide used in analgesia and receptor-binding studies.
NeuropeptidesMET-ENK
Methionine Enkephalin
An endogenous pentapeptide closely related to leucine enkephalin and derived from proenkephalin. It is studied for opioid receptor activity, pain modulation, and neuroimmune signaling.
