Descrição geral

Substance P is a small peptide produced by macrophages, lymphocytes, eosinophils, dendritic cells and nerves. It is part of the neurokinin group.


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 as an inhibitor of myosin light chain kinase in isolated lymphatic vessels from rat

Substance P acetate salt hydrate has been used in competition binding assays.

Ações bioquímicas/fisiológicas

NK-1 agonist; potent vasodilator and hypotensive agent; induces salivation; increases capillary permeability; induces mast cell degranulation; putative neurotransmitter in sensory (pain) afferents.
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.
