Tachykinins are generally C- terminal sequence, is a class of neuronal proteins that share Phe-Xaa-Gly-Leu- Met-NH 2. Tachycinins are distributed in the peripheral and central nervous system, where they bind to more than three receptor types. The NK 1 , NK 2 , and NK 3 receptors in the tachykinin receptor are defined by the preferred binding affinities of substrate P, neurokinin A (NKA) and neurokinin B (NKB), respectively.
The use of a tachykinin antagonist is hypersensitive; Immunological side effects; asthma; Bronchitis, allergic rhinitis including seasonal rhinitis and sinusitis; allergy; Contact dermatitis; Atopic dermatitis; Inflammatory bowel disease including Crohn's disease and ulcerative colitis; ≪ / RTI > and vomiting. ≪ Desc / Clms Page number 2 >
Tachycinin-mediated diseases and conditions are known to be diseases and conditions in which tachycinins are involved in all or part of the clinical symptoms thereof. Moreover, the involvement of tachycinin is not essential for causing certain tachykinin-mediated diseases and conditions. Tachykinin antagonists are useful for modulating or providing the therapeutic relief of such tachycinin-mediated diseases and conditions.
The present invention provides novel and useful tachykinin antagonists or stereoisomers or pharmaceutically acceptable salts thereof.
In a further aspect, the present invention provides a method of treating a subject suffering from a hypersensitivity reaction as a tachykinin antagonist; Immunological side effects; asthma; bronchitis; Allergic rhinitis including seasonal rhinitis and sinusitis; allergy; Contact dermatitis; Atopic dermatitis; Inflammatory bowel disease including Crohn's disease and ulcerative colitis; Comprising administering to a person in need of treatment of a tachycinin-mediated disease and condition comprising a therapeutically effective amount of a compound of formula I, do.
The hypersensitivity reaction may occur when the IgE antibody response is directed against non-toxic antigens such as pollen. During this reaction, pharmacological mediators such as histamine are continuously released by IgE-photosensitive oily cells, and acute inflammatory reactions generally occur. A characteristic of the reaction is that allergic rhinitis, in which reactions occur, including seasonal rhinitis and sinusitis; Lung diseases such as asthma; Allergic dermatitis, such as ulcers, vascular edema, eczema, atopic dermatitis and contact dermatitis; Gastrointestinal allergies such as allergies caused by food and drugs; convulsion; Motion Sickness; throw up; Diarrhea, and allergic diseases, including allergic allergies.
Histamine, an effect of which is activated through the activation of H 1 receptors, is an important mediator of the response involved in vasoactive hypersensitivity. In the acute state of allergic rhinitis, histamine H 1 receptor antagonists effectively inhibit itching, runny nose and sneezing of the nose associated with this condition. However, histamine H 1 receptor antagonists are less effective at removing nasal bleeding. Acute reactions to allergens in rhinitis often involve a chronic inflammatory response while hemorrhagic mucosa becomes sensitive to both antigenic and nonspecific stimulants. In addition, histamine H 1 receptor antagonists are ineffective in attenuating the symptoms of the chronic condition of the response.
The present invention provides novel and useful histamine antagonists, stereoisomers or pharmaceutically acceptable salts thereof of formula (I).
In a further aspect, the invention provides an allergic rhinitis comprising seasonal rhinitis and sinusitis as histamine antagonists; Lung diseases such as asthma; Allergic dermatitis, such as ulcers, vascular edema, eczema, atopic dermatitis, contact dermatitis; Gastrointestinal allergies such as allergies caused by food and drugs; convulsion; Motion Sickness; throw up; There is provided a method of treating such an allergic disease, comprising administering to a person in need of such treatment an allergic disease including diarrhea and an allergic disease a therapeutically effective amount of a compound of formula (I).
In addition to histamine, tachykinin, particularly substrate P, is also an important contributor to allergic reactions and exhibits some symptoms that are different from those caused by histamine reactions. This is caused by the release of tachycinin from the sensory neurons of the tertiary origin located in the peri-vascular and nasal mucosal lines promoted by stimulants such as histamine or inflammatory mediators.
The presence of rhinitis symptoms in patients with allergic rhinitis has been known to have a high level of substrate P in the nasal cavity (Mosimann et al. , J. Allergy Clin. Immunol. 92 , 95 (1993); Takeyama et al. , J. Pharma. Pharmacol. 46,41 (1994); And Watanabe et al. , Ann. Otol. Rhinol. and Laryngol. , 102 , 16 (1993)]. Administration of tachycinin locally or intravenously to humans induces nasal congestion, recovery of inflammatory cells, secretion, and capillary damage in allergic rhinitis. Nasal plugging caused by substrate P has been shown to be NK 1 receptor mediated [Braunstein et al. , Am. Rev. Respir. Dis. , ≪ / RTI > 144 , 630 (1991); Devillier et al. , Eur. Respir. J. 1 , 356 (1988)]. In addition, the sensory neuro-mediated effects, such as nasal irritation and hypersensitivity, in the terminal states of allergic reactions are also a consequence of tachycinin release [Anggard, Acta Otolaryngol. 113 , 394 (1993)). The release of tachycinin from the nerve of the nose after chronic capsaicin administration improves the person's rhinitis symptoms [Lacroix et al. , Clin. and Exper. Allergy, 21, 595 (1991) ].
The antagonistic effect of histamine on H 1 receptors is useful for the treatment of allergic diseases such as rhinitis. Similarly, the antagonism of tachykinin, particularly substrate P, to its receptor of interest is useful for the treatment of symptoms that occur simultaneously with allergic diseases. The potential advantage of antagonists with affinity at the H 1 and NK 1 receptors is therefore that they can reduce or prevent clinically prevalent allergic diseases mediated through both of these receptors.
More particularly, the present invention provides novel, useful compounds of formula 1, stereoisomers or pharmaceutically acceptable salts thereof, which are tachykinin antagonists and histamine antagonists.
In a further embodiment, the tachykinin antagonist and histamine antagonist of the present invention are selected from allergic rhinitis including seasonal allergies and sinusitis; And a therapeutically effective amount of a compound of formula (I) for the treatment of an allergic disease, including inflammatory bowel disease, including Clonorchis sinensis and western colitis.

Histamine at the Guinea Pig One) Antagonism
One of skill in the art will assess the ability of the compounds to inhibit histamine-mediated smooth muscle contraction to determine whether the compounds of the invention are antagonists to H 1 receptors in vitro. A male Hartley guinea pig weighing 200-450 g is sacrificed by suffocation with CO 2 . Remove one 20 cm long chair and cut into 2 cm pieces. Each sculpture piece is placed in a 37 ° C bath containing Tyrode's solution and immediately ventilated with 95% O 2 /5% CO 2 . The tea rod solution has a composition of 136.9 mM sodium chloride, 2.68 nM potassium chloride, 1.8 mM calcium chloride, 0.42 mM sodium dihydrogenphosphate, 11.9 mM sodium bicarbonate, and 5.55 mM Dextrose. The shrinkage is measured with a static transducer (Grass FTO3C) and recorded on a polygraph recorder and / or a computer. The plaque fragments are loaded at 1.0 g and equilibrated for at least 30 minutes before starting the experiment. Tissue is preincubated with vehicle or test compound at various concentrations and histamine challenge is performed.
Competitive H 1 receptor antagonists equilibrate the histamine dose-response curve to the right without diminishing the maximal response.
The efficacy of the antagonism is measured by the magnitude of migration and is expressed as the negative log-pA 2 value of the molar concentration of the antagonist that shifts the dose response curve to the right by two folds. The pA 2 value is calculated using a Schild analysis (reference: O. Arunlakshana and HO Schild, Br. J. Pharmacol Chemother. 14 , 48-58 (1958)). If the slope of the line obtained by the shield analysis is significantly different from (1), the compound acts as a competitive antagonist.

The cultured cells are maintained at 37 ° C under a 5% CO 2 environment.
On the day of the challenge, the medium was aspirated and cells were resuspended in RPMI-1640 medium containing 40 μg / ml bacthitracin, 4 μg / ml leupeptin and chimostatin, 0.1% bovine serum albumin, 10 μM thiorbine and 10 mM lithium chloride, Lt; / RTI > After 15 minutes, the test compound is added to the cells in a volume of 0.1 ml. After 15 minutes, the substrate P is added to various concentrations of UC11 cells to start the reaction, followed by incubation at 37 DEG C for 60 minutes in a final volume of 1 mL in a 5% CO 2 environment. The medium is aspirated to terminate the reaction, and methanol (0.1 ml) is added to each well. Two aliquots of methanol (0.5 ml) are added to the wells and the cells are recovered in chloroform-resistant tubes. Chloroform (1 ml) is added to each tube, followed by twice distilled water (0.5 ml). Samples are vortexed for 15 seconds and centrifuged at 1700 x g for 10 minutes. Aliquots (0.9 ml) on the aqueous (upper) phase are removed and double distilled water (2 ml) is added. The mixture is vortexed and loaded onto a 50% Bio-Rad AG 1-X8 (formate form, 100-200 mesh) exchange column (Bio-Rad Laboratories, Hercules, Calif.). The column is washed with 1) twice 10 ml of distilled water, 2) 5 ml of sodium tetraborate / 60 mM sodium formate, and 5 ml of 3M ammonium formate / 0.1M formic acid. The third eluate is recovered and counted in a 9 ml scintillation liquid. An aliquot of 50 [mu] l on top of the organic (lower) was removed, dried in a scintillation vial and counted in 7 ml of scintillation liquid.
The ratio of DPM in an aqueous phase aliquot (total inositol phosphate) to DPM in a 50 ul organic phase aliquot (total [ 3 H] inositol incorporated) is calculated for each sample. The data represent the antagonist-induced accumulation of [< 3 > H] -inositol phosphate to baseline levels in%. The ratio in the presence of the test compound and / or standard is compared to the ratio for the control sample (i. E., Without any facilitating antagonist).
The capacity-response graph is shown and the ability of test compounds to inhibit tachykinin-induced phosphopetaine inositol exchange is measured with the aid of a computer program. The data represent the% stimulation of total inositol phosphate accumulation to the baseline level and normalize to the maximum response exhibited by the substrate P. Shield assays are performed using a dose response curve to obtain a value indicative of the intensity of the competitive antagonist, which is a negative logarithm of the antagonist molarity that reduces the effect of the agonist dose to one half the expected effect of the agonist dose value, expressed in pA 2. The slope of the line obtained by shield analysis is not significantly different from (1), and the compound acts as a competitive antagonist.

One of skill in the art will be able to assess the ability of a compound to inhibit the formation of histamine (or substrate P) induced wheal in guinea pigs to determine whether the compounds of the present invention mediate the direct mediation of the hypersensitivity reaction in vivo Can be measured. Animals are anesthetized with pentobarbital (ip). Shake the skin, inject the histamine (or the substrate P) into the skin of the shaving site an appropriate number of times after administration of the test compound. The dose, route and frequency of administration may vary according to the method of the experiment. Such experimental methods are well known in the art. Immediately after the in-skin challenge, animals are given intravenous 1% Evan's blue dye to reveal the gauze. After challenging, the animals are inhaled by sucking CO 2 at an appropriate number of times. The skin is removed and the diameter of each well is measured in two vertical directions.
Gastric reactions use an index of edema response. Percent inhibition of the pore response is calculated by comparing the drug-treatment group with the Beckl-treatment group. The linear regression curve of dose-response inhibition is used to determine the ED 50 value (mg / kg) as a dose of a compound that inhibits histamine-induced skin ganglia by 50%.

The amount of substrate P-induced protein leakage through postcapillary venules is assessed by measuring the Evan blue dye accumulation in guinea pig organs.
When the putative antagonist is administered intravenously, the animal is anesthetized with pentobarbitol and then an evan blue dye (20 mg / kg, i.v., prepared in 0.9% sodium chloride solution) is injected. One minute after the dye administration, the antagonist was administered (iv), followed by administration of the substrate P (0.3 nmole / kg), and after 5 minutes, 50 ml of 0.9% sodium chloride solution was used to circulate the cardiac transition perfusion to remove excess dye do. The engine and main bronchial tubes are removed, blotted, dried and weighed.
If the putative antagonist is administered orally, the animal is anesthetized with pentobarbitol 1 hour after administration and infused with an evan blue dye (20 mg / kg, i.v., prepared in 0.9% sodium chloride solution). One minute after the administration of the dye, the substrate P (0.3 nmole / kg, i.v.) is administered, and after 5 minutes, 50 ml of 0.9% sodium chloride solution is used to circulate the cardiac transition perfusion to remove excess dye. The engine and main bronchial tubes are removed, blotted, dried and weighed.
After extracting the tissue from the formamide at 50 ° C for 24 hours, the dye amount is measured with a spectrophotometer at 620 nm. The value is subtracted from the background value (dye only without antagonist). The ED 50 (the amount of compound that inhibits the sunrise of the substrate P-induced plasma protein by 50%) is calculated by linear regression analysis.
