1.[3H][beta-Ala8]neurokinin A-(4-10): a novel, selective radioligand for the tachykinin NK2 receptor.
Goso C;Astolfi M;Parlani M;Manzini S Eur J Pharmacol. 1995 Dec 27;294(1):239-45.
The binding characteristics of the novel radioligand [3H][beta-Ala8]neurokinin A-(4-10) were assessed in hamster urinary bladder membranes. This labelled compound bound in a reversible, highly specific and concentration-dependent manner to a single class of high affinity binding sites with a Kd of 1.8 +/- 0.2 nM and a Bmax of 139 +/- 21 fmol/mg of protein. Specific binding of [3H][beta-Ala8]neurokinin A-(4-10) was displaced only by NK2, but not by NK1 or NK3, tachykinin receptor agonists and antagonists. Neurokinin A, [beta-Ala8]neurokinin A-(4-10), L 659877 [cyclo(Leu-Met-Gln-Trp-Phe-Gly)], MEN 10376 (H-Asp-Tyr-D-Trp-Val-D-Trp-D-Trp-Lys-NH2), MEN 10627 [cyclo(Met-Asp-Trp-Phe-Dap-Leu)cyclo(2 beta-5 beta)] and SR 48968 [(S)-N-methyl-N-[4-(4-acetylamino-4-phenylpiperidino)-2- (3,4-dichlorophenyl)butyl]benzamide] displaced the binding with Ki values of 0.4 +/- 0.1 nM, 1.9 +/- 0.36 nM, 3.05 +/- 0.1 nM, 7.9 +/- 0.4 microM, 0.36 +/- 0.02 nM and 2.5 +/- 0.9 nM, respectively. Functional data, obtained in isolated hamster urinary bladder strips with the newly developed tachykinin NK2 receptor antagonists (MEN 10627 and SR 48968), showed a good agreement with binding data. This novel radioligand could represent a new useful tool for the assessment of tachykinin NK2 receptor antagonists.
2.Tachykinins mediate contraction of the human lower esophageal sphincter in vitro via activation of NK2 receptors.
Huber O;Bertrand C;Bunnett NW;Pellegrini CA;Nadel JA;Nakazato P;Debas HT;Geppetti P Eur J Pharmacol. 1993 Aug 3;239(1-3):103-9.
The contractile response to natural tachykinins and selective peptide agonists for tachykinin receptors was studied in strips of circular smooth muscle of human lower esophageal sphincter in vitro. The effects of phosphoramidon, which inhibits neutral endopeptidase (EC. and of the non-peptide compounds, SR 48968 and CP-96,345, which selectively block NK1 and NK2 receptors, respectively, were also investigated. Substance P, neurokinin A and neurokinin B produced a concentration-dependent contractile response. The rank order of potency was neurokinin A > neurokinin B > substance P. Phosphoramidon (1 microM) potentiated the response to substance P without changing the order of potency of natural tachykinins. The NK2-selective agonist, ([ beta Ala8]neurokinin A-(4-10)), produced a concentration-dependent contraction. The NK1 ([Sar9,Met(O2)11]substance P, 1 microM) and NK3 ([MePhe7]neurokinin B, 1 microM) selective agonists, however, did not exert any contractile effect. The selective NK2 antagonist, SR 48968, potently inhibited in a concentration-dependent (10 nM-1 microM) manner the response to neurokinin A, without affecting the response to carbachol. The selective NK1 antagonist, CP-96,345 (1 microM), did not affect the response to neurokinin A.
3.Inflammatory and motor responses by tachykinins in the guinea-pig oesophageal sphincter.
Conte B;Parlani M;Lopez G;Cirillo R;Maggi CA;Manzini S J Auton Pharmacol. 1998 Oct;18(5):313-7.
1. The aim of this study was to characterize the tachykinin receptors involved in producing plasma protein extravasation and contractile responses of the guinea-pig oesophageal sphincter. 2. In anaesthetized guinea-pigs, the selective tachykinin NK-1 receptor agonist [Sar9,Met(O2)11]substance P produced plasma protein extravasation (PPE) which was not affected by the treatment with the tachykinin NK-2 receptor antagonist MEN 10627 (1 micromol kg(-1) i.v.) or the histamine H1-receptor antagonist, diphenhydramine (34.5 micromol kg(-1) i.v.). However, the [Sar9,Met(O2)11]substance P-induced PPE was blocked by the previous administration of the peptide tachykinin NK-1 receptor antagonist FK 888 or by the non-peptide antagonist SR 140333, yielding ED50 values of 1.1 +/- 0.2 and 0.01 +/- 0.004 micromol kg(-1) i.v., respectively. 3. The tachykinin NK-2 or NK-3 receptor agonists [beta-Ala8]neurokinin A (4-10) or [MePhe7]neurokinin B, respectively, produced a weak PPE at high doses. The effect of [MePhe7]neurokinin B-induced PPE was inhibited by SR 140333. 4. In the guinea-pig isolated oesophageal sphincter, [Sar9,Met(O2)11]substance P did not exert any contractile effect up to 10 microM. The selective tachykinin NK-2 receptor agonist ([beta-Ala8]neurokinin A (4-10), produced concentration-dependent contractions (pD2 = 7.
