| Application: | Substance P acetate salt hydrate has been: • used as a neurokinin 1 (NK1) receptor agonist for the activation of spinal nociceptive circuitry in mice • administered in central nucleus (ACE) in rat to study its positive reinforcing effects • used in competition binding assays • used as an inhibitor of myosin light chain kinase in isolated lymphatic vessels from rat |
| Biochem/physiol Actions: | NK-1 agonist; potent vasodilator and hypotensive agent. |
| Biochem/physiol Actions: | NK-1 agonist; potent vasodilator and hypotensive agent; induces salivation; increases capillary permeability; induces mast cell degranulation; putative neurotransmitter in sensory (pain) afferents. |
| Biochem/physiol Actions: | Substance P has proinflammatory effects on epithelial and immune cells. It has been associated with inflammatory diseases related to gastrointestinal and respiratory systems. Substance P modulates contractility of smooth muscles, transport of ions in the epithelium, vascular permeability and immune functions in the gut. |
| General description: | Research area: Cell Signaling Substance P is a member of the tachykinin family of peptides. It is encoded by the tachykinin precursor 1 (TAC1) gene mapped to human chromosome 7q21-q22. Substance P is a small peptide produced by macrophages, lymphocytes, eosinophils, dendritic cells and nerves. It is part of the neurokinin group. |
