Radioligand receptor binding inhibitory activity Binding inhibitory activity using receptor from human lymphoblast cells (IM-9) The method of M.A. Cascieri et al. "Molecular
Pharmacology 42, p.458 (1992)" was modified and used. The receptor was prepared from human lymphoblast cells (IM- 9). IM-9 cells (2 x 105 cells/ml) were inoculated and incubated for 3 days (one liter), which was then subjected to centrifuge for 5 minutes at 500xg to obtain cell pellets.
The pellets were washed once with phosphate buffer (Flow
Laboratories, CAT. No. 28-103-05), which were then crushed using Polytron.homogenizer "Kinematika, Germany" in 30 ml of 50 mM Tris-HCl buffer (pH 7.4) containing 120 mM sodium chloride, 5mM potassium chloride, 2 mg/ml chymostatin, 40 mg/ml bacitracin, 5 mg/ml phosphoramidon, 0.5 mM phenylmethyl sulfonyl fluoride, 1 mM ethylenediamine tetra-acetic acid, which was subjected to centrifuge at 40,000xg for 20 minutes. The residue was washed twice with 30 ml of the above-mentioned buffer, which was then preserved
frozen (-80°C) as a specimen of the receptor.
The specimen was suspended in a reaction buffer (50 mM Tri-HCl buffer (pH 7.4), 0.02% bovine serum albumin, 1 mM phenylmethylsulfonyl fluoride, 2 mg/chymostatin, 40 mg/ml bacitracin, 3 mM manganese chloride) and 100 ul portion was the suspension was used in the reaction. After addition of the sample and 125I-BHSP (0.46 KBq) , the reaction was allowed to proceed in 0.2 ml of reaction buffer at 25° C for 30 minutes . The amount of nonspecific binding was determined by adding substance P at a final concentration of 2 x 10"6M. After the reaction, using a cell harvester (290 PHD, Cambridge Technology, Inc, U.S.A.), rapid filtration was carried out through a glass filter (GF/B, Whatman, U.S.A.) to stop the reaction. After washing three times with 250 ul of 50 mM of Tris-HCl buffer (pH 7.4) containing 0.02% bovine serum albumin, the radioactivity remaining on the filter was determined with a gamma counter. Before use, the filter was immersed in 0.1% polyethyleneimine for 24 hours and air-dried. The antagonistic activity of each test compounds obtained in Reference Examples and Examples , in terms of the concentration necessary to cause 50% inhibition (IC50) under the above-described conditions, was expressed in nM [Table 1].

Graham, B. Hopkins, S. J. Powell, P. Danks , and I. Briggs [Biochemical and Biophysical Research Communications 177, pp 8-16(1991)]. Polymerase chain reaction (PCR) was performed at 95 °C for 1 min, 55 °C for 2 min, 72 ° C for 3 min for 50 cycles using taq DNA polymerase (Takara Shuzoh, Shiga, Japan), the above mentioned 3'- primer and a gene specific 5 ' -primer ( 5 ' - GAGCCAGGTCCTTTGTTCCAGACCCAGAAGCAG-3' ) which was also designed according to the published nucleotide sequence of human NK2 receptor cCNA reported by A.

The identity of the obtained clone was confirmed by nucleotide sequence analysis. In order to obtain an expression vector, the 1.3 kilobase-pair DNA fragment of human NK2 receptor cDNA was placed downstream of the SRa promoter [Y. Takebe, M. Seiki, J. Fujisawa, P. Hoy, K.

The resulting pellet was washed twice with the above mentioned buffer, which was then preserved frozen at -80 °C as a specimen of the receptor.
The specimen was suspended in reaction buffer (50 mM Tris-HCl buffer (pH 7.4) containing 0.02 % bovine serum albumin, 1 mM phenylmethylsulfonyl fluoride, 2 mg/ml chymostatin, 40 mg/ml bacitracin and 3 mM manganese chloride) to give a protein concentration of 0.6 mg/ml, and 0.1 ml of the portion of the suspension was employed in the reaction. After addition of a test compound and (2- [125l]iodohistidyl1)Neurokinin A (Amersham, UK) (74TBq/mmol, 1.48 kBq, final concentration of 0.1 nM) to a final volume of 0.2 ml, the mixture was incubated at room temperature for 60 min in a 96-well plate. Then the mixture was filtered through a glass fiber filter (UniFilter-96 , GF/B, Packard Instrument, Inc., USA) under reduced pressure on a Filter Mate Cell Harvester (Packard Instrument, Inc. , USA) . After washing the filter three times with 0.3 ml of the above mentioned reaction buffer, the radioactivity remaining on the filter was determined on a TopCound Micro Scintillation Counter (Packard Instrument, Inc., USA). The nonspecific binding was defined as the binding activity in the presence of 10 x 10"6 M of neurokinin A (Peptide Instituted, Osaka, Japan). The filters were presoaked overnight in 0.5 % bovine serum albumin. The antagonistic activity of test compounds obtained in Reference Examples was expressed in nM in terms of the concentration necessary to cause 50 %

From Table 2 , it is apparent that the heterocyclic compounds (I) or salts thereof have excellent inhibitory activity toward human NK2 receptor. Experimental Example 3
Inhibitory effect on plasma extravasation induced by capsaicin in trachea of guinea pigs Guinea pigs (Hartley type white male guinea pige) , (n=6) were anesthetized with 35 mg/kg of pentobarbital injected intraperitoneally (i.p.), then test compounds were administered intravenously (i.v.). After 5 minutes, a mixed solution of capsaicin (150 mg/kg) and Evans 'blue dye (20 mg/kg) was administered intravenously to cause reaction .
Ten minutes later, test animals were sacrificed by cutting the aorta, then perfused through pulmonary artery with 50 ml of physiological saline. The trachea was excised, and its wet weight was measure. The trachea was incubated at room temperature in 1 ml of acetone-0.3 % sodium sulfate (7:3) overnight and Evans ' blue dye was extracted from the trachea. The extract solution was centrifuged at 2800 rp for 5 minutes . The amount of Evans ' blue dye in the supernatant was quantified by measuring absorbance at 620 mm.
The reaction of accelerating the permeability of blood vessels is expressed in terms of the amount of Evans' blue ( p g ) per trachea unit weight (g) and the effect of drug was evaluated by calculating the degree of inhibition (% inhibition) according to the following equation:
Inhibition I blood - vessel permeability in a drug administration group - blood - vessel permeability in a capsaicin - untreated group
1 = :100 blood - vessel permeability in a control group - blood - vessel permeability in a capsaicin - untreated group
