Background and purpose: The tachykinin NK2 receptor antagonist ibodutant is under phase III clinical investigation to treat female patients affected by irritable bowel syndrome. Aim of this studyThe NK1 receptor antagonist competitively binds to the NK1 receptor, which blocks the binding of substance P and prevents the emetic signal being transmitted. NK1 receptor antagonists can be used in conjunction with 5HT3receptor antagonists and corticosteroids to augment their antiemetic activity. tachykinin nk2 receptor antagonist

Moreover, tachykinin NK 2 receptor antagonists, such as nepadutant (Catalioto et al. , 1998), exert a modulatory role on colonic visceral hyperalgesia induced by experimental inflammation or stress in animals (Buno et al. , 1997, for review; Kiss et al. , 1999, Olivar et al. , 1999, Toulouse et al. , 2000). From these preclinical data, it is anticipated that these drugs could represent a novel type of treatment in

NK 2 receptor antagonists are also being investigated for the treatment of depression and anxiety. NK 2 antagonists typically fall into two categories; peptide and nonpeptide. Peptidebased antagonists are usually generated by amino acid substitution of the endogenous tachykinin The tachykinin receptor 1 (TACR1) also known as neurokinin 1 receptor (NK1R) or substance P receptor (SPR) is a G protein coupled receptor found in the central nervous system and peripheral nervous system. The endogenous ligand for this receptor is Substance P, although it has some affinity for other tachykinins. tachykinin nk2 receptor antagonist There are three known mammalian tachykinin receptors termed NK1, NK2 and NK3. All are members of the 7 transmembrane Gprotein coupled receptor family and induce the activation of phospholipase C, producing inositol triphosphate.

Apr 22, 2004 Tachykinin NK2 receptors are expressed in the gastrointestinal tract of both laboratory animals and humans. Experimental data indicate a role for these receptors in the regulation of intestinal motor functions (both excitatory and inhibitory), secretions, inflammation and visceral sensitivity. tachykinin nk2 receptor antagonist The tachykinin NK2 receptor is widel y distributed in the peripheral and central nervou s system. It mediates numerous pharmacological effects of neurokinin A, suggesting that the tachykinin NK2 Tachykinin NK2 Receptor Antagonists SpringerLink MEN (nepadutant) is a potent, selective and competitive antagonist of tachykinin NK2 receptors. The objective of the present study was to assess the capability of the drug to antagonize the stimulatory effects of neurokinin A (NKA) on gastrointestinal motility, as well as to change the fasting migrating motor complex (MMC). A novel tachykinin NK2 receptor antagonist prevents motilitystimulating effects of neurokinin A in small intestine MEN (nepadutant) is a potent, selective and competitive antagonist The objective of the present study was to assess the capability of the drug to antagonize Thirtyfour Tachykinin NK2 receptor antagonists are potentially useful in the treatment of various CNS, gastrointestinal and genitourinary diseases: they have been evaluated in advanced clinical studies for depression, anxiety, irritable bowel syndrome. . About 50 patents were published in the years 2006 2010 on tachykinin NK2 receptor antagonists,
