  • Tachykinins are distributed in both the central nervous system and the peripheral nervous system. Tachykinin receptors have been recognized and are classified into three types: NK 1 , NK 2 , NK 3 .
  • Substance P is the endogenous ligand for NK 1 receptors, neurokinin A (NK A ) for NK 2 receptors and neurokinin B (NK B ) for NK 3 receptors.

  • the pharmacological studies of the peptide and non-peptide antagonists of the NK 1 and NK 2 receptors have shown that their affinities for these receptors as well as their pharmacological activities are very strongly dependent on the species, most probably due to slight differences in the sequences of amino acids, thus inducing very fine structural variations of these receptors from one species to another (J.

  • NK 3 receptor By very strong affinity for the human NK 3 receptor is meant an affinity characterized by an inhibition constant Ki generally less than 5.10 -9 M.
  • Ki is defined by the Cheng-Prusoff relation (in Receptor Binding in Drug Research, eds. RA O'BRIEN. Marcel Dekker, New York, 1986):
