TEST EXAMPLE 1
In Vitro DP Inhibitory Activity
(730) 1) DP Inhibitory Activity in Human Platelets
(731) Thirty milliliter of blood was drown from healthy human into a syringe preloaded with 1/9 volume of 3.8% citrate sodium. The blood was centrifuged with 180 g for 10 min at room temperature and the upper plasma layer was collected as platelet rich plasma (PRP). The PRP was transferred to plate and treated with 3-isobutyl-1-methylxanthin (IBMX; 0.5 nM) for 5 min. Then the compounds of the present invention were added to the plate and after 10 min, 300 nM of PGD2 was added. The reaction was stopped with 1 mmol/l hydrogenchlolide after 2 min of PGD2 addition, and platelet was lysed by adding 12% Triton X-100. The concentration of cAMP in the supernatant of the platelet lysate was quantified using homogenous time resolved fluorescence (HTRF). Inhibition ratio was defined by cAMP increase with and without compound, and 1050 for each compound was calculated from inhibitory curve. Results were shown in Table 98.
(732) 2) Human DP1 Inhibitory Activity in DP1-Expressing Cell
(733) Human DP1 receptor expressing Jurkut cell was suspended in buffer (HBSS, 20 mM HEPES buffer pH 7.4, 0.1 mM IBMX, 0.2 mM (4-(3-butoxy-4-methoxy-benzyl) imidazolidone (RO 20-1724)) at concentration of 1.2×10.sup.6 cells/ml. Compounds of the present invention was added to the cell suspension and the mixture was incubated for 10 min at 37° C. PGD2 was added at final concentration of 60 nM, and the mixture was incubated for 60 min at 37° C. The concentration of cAMP in the cell lysate was measured using the cAMP dynamic 2 kit (Cisbio Bioassays, France) according to the manufacturer's instructions. Inhibition ratio was defined by cAMP increase with and without compound, and IC50 for each compound was calculated from inhibitory curve
(734) Results were shown in Table 98 as cAMP (nM). Compounds were categorized as AA (cAMP is less than 100 nM) and A (cAMP is more than 100 nM and less than 5000 nM) as shown in Table 99 and 100.
(735) 3) DP Receptor Binding Inhibitory Activity
(736) Cell membrane was prepared from DP-expressing cells by homogenization and ultracentrifuge. Compounds of the present invention and [.sup.3H]-PGD2 were mixed in plate, then cell membrane was added and the mixture was incubated on ice for 2 hr. The concentration of [.sup.3H]-PGD2 was determined as equal to Kd calculated from Scatchard plot. Using cell harvester, the membrane was collected with glass fiber filter, washed 8 times and dried up, and radio activity on the filter was measured with scintillation counter (MicroBeta). Specific binding was defined as difference between total and non-specific binding (radio activity with 10 μM PGD2). Ki values for each compound were calculated from displacement curve.

TEST EXAMPLE 2
In Vitro CRTH2 Inhibitory Activity
(740) 1) CRTH2 Receptor Binding Inhibitory Activity
(741) Cell membrane was prepared from CRTH2-expressing K562 cell. The cell membrane (20 μg/well) was mixed with reaction buffer (50 mM Tris/HCl, pH 7.4, 10 mM MgCl2). Then, [.sup.3H]-PGD.sub.2 was added to the mixture and incubated for 60 min at room temperature. The concentration of [.sup.3H]-PGD.sub.2 was determined as equal to Kd calculated from Scatchard plot. Then, the mixture was filtrated with glass paper immediately. The filter paper was washed several times and radio activity on the filter was measured. Specific binding was defined as difference between total and non-specific binding (radio activity with 10 μM PGD.sub.2). Ki values for each compound were calculated from displacement curve.

The TA100 strain was added to 120 mL of the Exposure medium relative to 3.16 mL of the bacterial solution to prepare a test bacterial solution. Each 12 μL of a DMSO solution of the compound of the present invention (8 stage dilution from maximum dose 50 mg/mL at 2-fold ratio), DMSO as a negative control, 50 μg/mL of 4-nitroquinoline-1-oxide DMSO solution for the TA98 strain, 0.25 μg/mL of 2-(furyl)-3-(5-nitro-2-furyl)acrylamide DMSO solution for the TA100 strain under the non-metabolism activating condition, 40 μg/mL of 2-aminoanthracene DMSO solution for the TA98 strain, 20 μg/mL of 2-aminoanthracene DMSO solution for the TA100 strain under the metabolism activating condition as a positive control, and 588 μL of the test bacterial solution (a mixed solution of 498 μl of the test bacterial solution and 90 μL of S9 mix under the metabolism activating condition) were mixed, and this was shaking-cultured at 37° C. for 90 minutes. 460 μL of the bacterial solution exposed to the compound of the present invention was mixed with 2300 μL of an Indicator medium (Micro F buffer containing biotin: 8 μg/mL, histidine: 0.2 μg/mL, glucose: 8 mg/mL, Bromo Cresol Purple: 37.5 μg/mL), each 50 μL was dispensed into microplate 48 wells/dose, and this was subjected to stationary culturing at 37° C. for 3 days.

(835) Appropriate amounts of the compound of the present invention is put into vials and 200 μL of JP-1st Fluid (water is added to 2.0 g of sodium chloride in 7.0 mL of hydrochloride acid to reach 1000 mL), JP-2nd Fluid (water is added to 500 mL of phosphate buffer solution with a pH of 6.8) and 20 mmol/L sodium taurocholate (TCA) /JP-2nd Fluid (JP-2nd Fluid is added to 1.08 g of TCA in JP-2nd Fluid to reach 100 mL) is added to each vial. When the compound is completely dissolved, appropriate amount of compound is added. After shaken for 1 hour at 37° C., the mixture is filtered and 100 μL of methanol is added to 100 μL of each filtrate (double dilution). Dilution magnification is changed if necessary. After it is confirmed whether there are air bubbles and precipitates in the vials, the vials are shaken with tight stopper. The compound concentration is determined with HPLC by the absolute calibration method.

Next, the necessary amount is provided to a stainless-steel vessel and the content is diluted with the remaining propellant. A valve unit is fitted to the vessel.
FORMULATION EXAMPLE 4
(845) A tablet containing 60 mg of an active ingredient is prepared as follows;
(846) TABLE-US-00107 active ingredient 60 mg starch 45 mg microcrystalline cellulose 35 mg polyvinylpyrrolidone (10% aq. solution) 4 mg sodium carboxymethylstarch 4.5 mg magnesium stearate 0.5 mg talc 1 mg Total 150 mg
(847) The active ingredient, starch and cellulose are put through a sieve of No. 45 mesh US and mixed sufficiently. The resulting powder is mixed with a solution containing polyvinylpyrrolidone and the mixture is put through a sieve of No. 14 mesh US. The granulated powder is dried at 50° C. and put through a sieve of No. 18 mesh US. Sodium carboxymethylstarch, magnesium stearate and talc are put through a sieve of No. 60 mesh US in advance and added to the granulated powder, mixed and compressed by a tableting machine to give a tablet weighing 150 mg/tablet.
FORMULATION EXAMPLE 5
(848) A capsule containing 80 mg of an active ingredient is prepared as follows;
(849) TABLE-US-00108 active ingredient 80 mg starch 59 mg microcrystalline cellulose 59 mg magnesium stearate 2 mg Total 200 mg
(850) The active ingredient, starch, cellulose and magnesium stearate are mixed, put through a sieve of No. 45 mesh US and filled in hard-gelatin capsules to give a capsule formulation containing 200 mg/capsule.
FORMULATION EXAMPLE 6
(851) A suppository containing 225 mg of an active ingredient is prepared as follows;
(852) TABLE-US-00109 active ingredient 225 mg saturated fatty acid gliceride 2000 mg Total 2225 mg
(853) The active ingredient is put through a sieve of No. 60 mesh US and suspended in the saturated fatty acid gliceride melted by the least amount of heating. Then, the mixture was cooled in a mold of 2 g in appearance.
FORMULATION EXAMPLE 7
(854) A suspension containing 50 mg of an active ingredient is prepared as follows;
(855) TABLE-US-00110 active ingredient 50 mg sodium carboxymethylcellulose 50 mg syrup 1.25 ml solution of benzoic acid 0.10 ml flavor q.v. pigment q.v. Total (adding purified water) 5 ml
(856) The active ingredient is put through a sieve of No. 45 mesh US and mixed with sodium carboxymethylcellulose and syrup to give a smooth paste. The solution of benzoic acid and flavor are diluted with a part of water and added to the paste and stirred. A necessary amount of water is added to give the objective suspension.
FORMULATION EXAMPLE 8

INDUSTRIAL APPLICABILITY
(860) The present inventors found that novel heterocyclic derivatives have PGD2 receptor antagonistic activity (DP receptor antagonistic activity, CRTH2 receptor antagonistic activity, and/or, antagonistic activity against both the DP receptor and CRTH2 receptor). These compounds are thought to be effective for treating allergic diseases.
