The Uses of 2-Pyridylethylamine
2-(2-Aminoethyl)pyridine is used as active pharmaceutical ingredients.
Definition
ChEBI: An aminoalkylpyridine that is pyridine substituted by a ethanamino group at position 2.
Biological Activity
Low doses of histamine or H1R agonist 2-pyridylethylamine (2-PEA) into the knee-joint were found to decrease formalin-induced articular nociception in rats. The pharmacological blockade and neurotoxic ablation of cells expressing neuropeptide Y1 receptor (Y1R) in the spinal cord were able to prevent the antinociceptive effect produced by the intra-articular administration of the histamine H1 receptor (H1R) agonist, 2-pyridylethilamine (2-PEA), in the formalin-induced articular incapacitation in rats[1].
