Biochem/physiol Actions

Talnetant (SB-223,412) is a highly selective antagonist of neurokinin 3 receptor with a Ki (NK3) = 1 nM >10000 (NK1) >140 (NK2). Neurokinins (tachykinins) are members of a family of at least three neuropeptides, substance P, neurokinin A, and neurokinin B (NKB), with each mediating their biological effects through binding to a preferred G-protein-coupled receptor termed NK1, NK2, or NK3, respectively. All three NK receptors are expressed in regions of the central nervous system that are related to emotion and cognition (i.e., amygdala and hippocampus) and have been linked to various degrees in psychiatric disorders. Neurokinin receptors, including NK3 receptors, are also expressed in the motor and sensory systems of the digestive tract. Talnetant was in clinical trials for both irritable bowel syndrome and schizophrenia.
Talnetant is a highly selective antagonist of neurokinin 3 receptor.
