      More particularly, it relates to spiroheterocyclic ring derivatives of the formula (I)  
                 
 
 (wherein all the symbols have the same meaning as defined hereinafter), quaternary ammonium salts thereof, N-oxides thereof, non-toxic salts thereof, the methods for preparation thereof and pharmaceutical compositions comprising thereof, as an active ingredient. 
 
     BACKGROUND ART  
      Chemokine is known as a basic protein having endogeneous leukocyte chemotactic and activating abilities and strong heparin-binding ability. At present, it is considered that chemokine is related to not only the control of infiltration of specific leukocyte at the time of inflammations and immune responses but also the development and homing of lymphocyte under physiological conditions and migration of hemocyte precursor cells and somatic cells.  
      Differentiation, proliferation and cell death of hemocytes are controlled by various types of cytokine. In the living body, inflammations are found topically and differentiation, maturation and the like of lymphocytes are carried out at certain specified sites. That is, various necessary cells migrate into certain specified sites and accumulate therein to cause a series of inflammations and immune responses. Accordingly, migration of cells is also an indispensable phenomenon in addition to differentiation, proliferation and death of cells.  
      Migration of hemocytes in the living body starts firstly in the development stage by the shift of hematopoiesis started in the AGM region into permanent hematopoiesis in bone marrow via fetal liver. Furthermore, precursor cells of T cells and thymus dendritic cells migrate from the fetal liver into the bone marrow and then into the thymus gland and cytodifferentiate under thymus environment. The T cell which received clone selection migrates into secondary lymphoid tissues and takes part in an immune response in the periphery. The Langerhans&#39; cell of the skin activated and differentiated by capturing an antigen migrates into the T cell region of a topical lymph node and activates naïve T cell therein as a dendritic cell. The memory T cell performs its homing again into the lymph node via lymphatic and blood vessels. Also, B cell, T cell in the intestinal epithelium, γδ T cell, NKT cell and dendritic cell migrate from bone marrow without passing through the thymus gland and differentiate to take part in an immune response.  
      Chemokine is deeply related to the migration of these various cells. For example, MIP3β, SLC and its receptor CCR7 play an important role in the migration and homing of naïve T cell, memory T cell and the mature dendritic cell which captured an antigen into a topical lymphoid tissue for the dendritic cells to encounter efficiently with the T cells. The T cell and dendritic cell necessary for controlling antigen-specific immune responses are hardly observed in the secondary lymph node of a PLT mouse having deficiency in the expression of SLC [ J. Exp. Med.,  189(3), 451 (1999)].  
      MDC, TARC and its receptor CCR4 play an important role in the migration of Th2 cell into topical sites in immune and inflammatory responses in which the Th2 cell is related. In a rat fluminant hepatitis model ( P. acnes +LPS), an anti-TARC antibody suppressed increase of the amount of ALT in blood and increase of the expressing amounts of TNFα and FasL in the liver and also improved lethality of the rats [ J. Clin. Invest.,  102, 1933 (1998)]. Also, an anti-MDC antibody decreased the number of eosinophils accumulated in the lung interstitium and suppressed airway hypersensitivity in a mouse OVA-induced airway hypersensitivity model [ J. Immunology,  163, 403 (1999)].  
      MCP-1 and its receptor CCR2 are related to the infiltration of macrophage into inflammation sites. An anti-MCP-1 antibody showed an effect to suppress infiltration of monocyte and macrophage into glomerulus in a rat anti-Thy1.1 antibody glomerular nephritis model [ Kidney Int.,  51, 770 (1997)].  
      Thus, chemokine receptors are greatly related to the control of inflammation and immune responses through a mechanism in which they are expressed at certain specified periods in variously specific cells and the effector cells are accumulated in a region where chemokine is produced.  
      Acquired immunodeficiency syndrome (called AIDS) which is induced by human immunodeficiency virus (hereinafter referred to as “HIV”) is one of the diseases of which their therapeutic methods are most earnestly desired in recent years. Once infection with HIV is completed in a CD4-positive cell which is a principal target cell, HIV repeats its proliferation in the body of the patient and, sooner or later, completely destroys T cell which takes charge of the immunological function. During this process, the immunological function is gradually reduced to cause fever, diarrhea, lymph node enlargement and the like various immunodeficiency conditions which are apt to cause complications with  pneumocystis carinii  pneumonia and the like various opportunistic infections. Such conditions are the onset of AIDS, and it is well known that they induce and worsen Kaposi sarcoma and the like malignant tumors.  
      As the recent preventive and therapeutic methods for AIDS, attempts have been made to, e.g., (1) inhibit growth of HIV by the administration of a reverse transcriptase inhibitor or a protease inhibitor and (2) prevent or alleviate opportunistic infections by the administration of a drug having immunopotentiation activity.  
      Helper T cells which take charge of the central of immune system are mainly infected with HIV. It is known since 1985 that HIV uses the membrane protein CD4 expressing on the membrane of T cells in the infection [ Cell,  52, 631 (1985)]. The CD4 molecule is composed of 433 amino acid residues, and its expression can be found in macrophages, some B cells, vascular endothelial cells, Langerhans&#39; cells in skin tissues, dendritic cells in lymphoid tissues, glia cells of the central nervous system and the like, in addition to the mature helper T cells. However, since it has been revealed that the infection with HIV is not completed by the CD4 molecule alone, a possibility has been suggested on the presence of factors other than the CD4 molecule, which are related to the infection of cells with HIV.  
      In 1996, a cell membrane protein called Fusin was identified as a factor other than the CD4 molecule, which is related to the HIV infection [ Science,  272, 872 (1996)]. It was confirmed that this Fusin molecule is a receptor (namely, CXCR4) of stromal derived factor-1 (hereinafter referred to as “SDF-1”). In addition, it was confirmed also in vitro that the SDF-1 specifically inhibits infection of T cell tropic (X4) HIV [ Nature,  382, 829 (1996),  Nature,  382, 833 (1996)]. That is, it is considered that the HIV infection was inhibited by the binding of SDF-1 to CXCR4 preceding HIV, thereby depriving HIV of a foothold for infecting cells.  
      Also at that time, it was discovered that another chemokine receptor CCR5, which is a receptor of RANTES, MIP-1α and MIP-1β, is also used at the time of the infection with a macrophage tropic (R5) HIV [ Science,  272, 1955 (1996)].  
      Accordingly, substances which can compete With CXCR4 and CCR5 for HIV, or which can bind to HIV virus thus causing the virus unable to bind to CXCR4 and CCR5, could become HIV infection inhibitors. Also, there is a case in which a low molecular compound initially discovered as an HIV infection inhibitor was actually a CXCR4 antagonist [ Nature Medicine,  4, 72 (1998)].  
      Based on the above, it is considered that the chemokine/chemokine receptors are deeply related to the inflammation, immune disease or HIV infection. For example, it is considered that they are related to the inhibition of various inflammatory diseases, asthma, atopic dermatitis, nettle rash, allergic diseases (allergic bronchopulmonary aspergillosis, allergic eosinophilic gastroenteritis and the like), glomerular nephritis, nephropathy, hepatitis, arthritis, chronic rheumatoid arthritis, psoriasis, rhinitis, conjunctivitis and ischemia-reperfusion injury, in the treatment of multiple sclerosis, ulcerative colitis, acute respiratory distress syndrome, shock accompanied by bacterial infection, diabetes mellitus and autoimmune diseases, and in transplanted organ rejection reactions, immunosuppression, metastasis prevention and acquired immunodeficiency syndrome.  
      On the other hand, in specification of WO97/11940, it is described that compounds of the formula (Z)  
                 
          (wherein the atoms A iZ  and B iZ  are independently selected from carbon, nitrogen, oxygen or sulfur, provided that at least one atom of A iZ  is carbon, and at least one atom B iZ  is carbon;     each of the rings of the spirobicycle formed by A iZ  and B iZ  may be partly unsaturated,     pZ and qZ are independently numbers from 2 to 6,     mz is a number from 0 to pZ,     R 10Z  is the same or different and is a non-interfering substituent independently selected from hydrogen, alkyl, halosubstituted alkyl, alkenyl, alkynyl, cycloalkyl, ═O, ═S etc.,     nZ is a number from 0 to qZ,     R 0Z  is the same or different and is a non-interfering substituent independently selected from hydrogen, alkyl, halosubstituted alkyl, alkenyl, alkynyl, cycloalkyl, ═0, ═S etc.,     the linking group -(L Z )- is a bond or a divalent substituted or unsubstituted chain of from 1 to 10 atoms selected from the group consisting of carbon, nitrogen, sulfur, and oxygen,     Q Z  is a basic group containing one or more basic radicals, and     R 3Z  is an acidic group containing one or more acid radicals) are useful in inhibition platelet aggregation.

      Pharmacological Activities:  
      Efficacy of the compounds of the invention represented by general formula (I) was confirmed, e.g., by the following tests.  
      As described in the foregoing, in order to carry out screening of a compound capable of inhibiting binding of HIV to CXCR4 or CCR5 which is a receptor on the CD4-positive cell, it is a more directive method to carry out it in an assay system that uses HIV virus. However, the use of a large amount of HIV virus in the screening is not practical due to a difficulty in handling it. On the other hand, since both the macrophage tropic (R5) HIV-1 and the ligands, that is, RANTES, MIP-1α and MIP-1β, bind to CCR5, it can be presumed that certain common characteristics are present in the CCR5 binding sites of the HIV side and the RANTES, MIP-1α and MIP-1β sides, and in the binding sides of CCR5 to the ligands, that is, RANTES, MIP-1α and MIP-1β, and HIV. Accordingly, in order to find a compound capable of inhibiting adsorption of HIV virus to cells, which has an inhibitory mechanism different from the current anti-AIDS drugs (reverse transcription inhibitors and protease inhibitors), it is possible to use an assay system that uses an endogeneous CCR5 ligand, RANTES, MIP-1α or MIP-1β instead of HIV.  
      Specifically, e.g., since CCR5 is a G protein-coupled seven transmembrane type receptor, an assay system in which the effect of RANTES on the transient increase of Ca ion induced via CCR5 is measured can be carried out as an assay system for screening a compound capable of inhibiting binding of RANTES to CCR5. Since both of the T cell tropic (X4) HIV and SDF-1 bind to CXCR4, similar idea can be considered.  
      Test Methods:  
      (1) Isolation of Human CCR5 Gene  
      Human placental cDNA was prepared using Marathon cDNA amplification kit (Clontech). PCR primers hCCR5XbaI-F1: 
      5′-AGCTAGTCTAGATCCGTTCCCCTACMGAAACTCTCC-3′ (SEQ ID NO:1) and hCCR5XbaI-R1:     5′-AGCTAGTCTAGAGTGCACAACTCTGACTGGGTCACCA-3′ (SEQ ID NO:2) were designed based on the sequence of GenBank U54994.    

      Using the human placental cDNA as the template and using Ex Taq (Takara), PCR reaction (2 minutes at 95° C.→(30 seconds at 95° C., 45 seconds at 60° C., 1 minute at 72° C.)×35 times) was carried out. The thus amplified PCR product was subjected to a 1% agarose gel electrophoresis, purified using QIAquick Gel Extraction Kit (QUIAGEN) and then digested with a restriction enzyme XbaI. The digested fragments were ligated to an expression vector pEF-BOS-bsr using DNA Ligation Kit Ver. 2 (Takara) and transformed into  Escherichia coli  DH5a. By preparing the resulting plasmid pEF-BOS-bsr/hCCR5, its DNA sequence was verified.  
      (2) Culturing of CHO Cell  
      CHO-dhfr(−) was cultured using Ham&#39;s F-12 (containing fetal bovine serum (10%), penicillin (50 U/ml) and streptomycin (50 mg/ml)). Also, the transduced cell was cultured by adding blasticidin (5 mg/ml) to the above medium.  
      (3) Transduction into CHO Cell  
      The plasmid pEF-BOS-bsr/hCCR5 was transduced into the CHO-dhfr(−) cell using DMRIE-C reagent (Gibco BRL). After 48 hours, the medium was replaced with a medium containing 5 mg/ml of blasticidin to carry out the selection, thereby establishing a stably over-expressing cell.  
      (4) Inhibition Test on the Binding of RANTES to CCR5 (Activity of RANTES to Induce Transient Increase of Ca Ion)  
      The thus established human CCR5 stably over-expressing CHO cell (CCR5/CHO cell) was suspended in Ham&#39;s F-12 medium containing FBS (10%) and dispensed in 3.0×10 6  cells/well portions into a 96 well plate. One day after culturing at 37° C., the culture supernatant was discarded, and Ham&#39;s F-12 medium (containing Fura-2AM (5 μM); Probenecid (2.5 mM) and HEPES (20 mM; pH 7.4)) was dispensed in 80 i/well portions to carry out 1 hour of incubation at 37° C. under shaded condition. After washing twice with 1× Hanks/HEPES (20 mM; pH 7.4) solution, the same solution was dispensed in 100 μl/well portions. Each of the test compounds was added to the thus Fura-2AM-incorporated CCR5/CHO cell, and 3 minutes thereafter, a recombinant human RANTES (PeproTach) diluted with 1× Hanks/HEPES (20 mM; pH 7.4) solution was added thereto to a final concentration of 10 nM. Transient increase in the intracellular Ca 2+  concentration induced by the human RANTES was measured using a Ca 2+  detector for 96 well use (Hamamatsu Photonics), and inhibition ratio (%) of the test compound was calculated by the following calculation formula. 
 
Inhibition ratio=( Ec−Ea )/ Ec× 100 
          Ec: measured value of Ca 2+  transient increase by RANTES     Ea: measured value of Ca 2+  transient increase by RANTES when a test compound was added        

      As a result, the compounds of the invention showed an inhibition ratio of 50% or more at 10 μM. For example, the compound of Example 1(1) showed an IC 50  value of 0.74 μM, and the compound of Example 5 an IC 50  value of 0.012 μM.  
      An assay system for finding a compound having adsorption inhibition effect on CCR5 directional HIV strain was described in the foregoing, and it is possible as a matter of course to find a compound capable of inhibiting the activity of CCR5 or a ligand thereof using this system. In the same manner, it is possible to find a compound capable of inhibiting the activity of other chemokine receptor or a ligand thereof.  
      Toxicity:  
      The toxicity of the compounds of the present invention is very low and therefore the compounds may be considered safe for pharmaceutical use.

In the human adult, the doses per person are generally from 1 mg to 1000 mg, by oral administration, up to several times per day, and from 1 mg to 100 mg, by parenteral administration (preferably intravenous administration), up to several times per day, or continuous administration from 1 to 24 hours per day from vein.  
      As mentioned above, the doses to be used depend upon various conditions. Therefore, there are cases in which doses lower than or greater than the ranges specified above may be used.  
      The compounds of the present invention may be administered in the form of, for example, solid forms for oral administration, liquid forms for oral administration, injections, liniments or suppositories for parenteral administration.  
      Solid forms for oral administration include compressed tablets, pills, capsules, dispersible powders, and granules. Capsules include hard capsules and soft capsules.  
      In such solid forms, one or more of the active compound(s) may be admixed with vehicles (such as lactose, mannitol, glucose, microcrystalline cellulose, starch), binders (such as hydroxypropyl cellulose, polyvinylpyrrolidone or magnesium metasilicate aluminate), disintegrants (such as cellulose calcium glycolate), lubricants (such as magnesium stearate), stabilizing agents, and solution adjuvants (such as glutamic acid or aspartic acid) and prepared according to methods well known in normal pharmaceutical practice. The solid forms may, if desired, be coated with coating agents (such as sugar, gelatin, hydroxypropyl cellulose or hydroxypropylmethyl cellulose phthalate), or be coated with two or more films. And further, coating may include containment within capsules of absorbable materials such as gelatin.  
      Liquid forms for oral administration include pharmaceutically acceptable solutions, suspensions and emulsions, syrups and elixirs. In such forms, one or more of the active compound(s) may be dissolved, suspended or emulized into diluent(s) commonly used in the art (such as purified water, ethanol or a mixture thereof). Besides such liquid forms may also comprise some additives, such as wetting agents, suspending agents, emulsifying agents, sweetening agents, flavoring agents, aroma, preservative or buffering agent.  
      Injections for parenteral administration include sterile aqueous, suspensions, emulsions and solid forms which are dissolved or suspended into solvent(s) for injection immediately before use. In injections, one or more of the active compound(s) may be dissolved, suspended or emulized into solvent(s). The solvents may include distilled water for injection, physiological salt solution, vegetable oil, propylene glycol, polyethylene glycol, alcohol, e.g. ethanol, or a mixture thereof. Injections may comprise some additives, such as stabilizing agents, solution adjuvants (such as glutamic acid, aspartic acid or POLYSORBATE80 (registered trade mark)), suspending agents, emulsifying agents, soothing agent, buffering agents, preservative. They may be sterilized at a final step, or may be prepared and compensated according to sterile methods. They may also be manufactured in the form of sterile solid forms such as freeze-dried products, which may be dissolved in sterile water or some other sterile diluent(s) for injection immediately before use.  
      Other forms for parenteral administration include liquids for external use, ointments and endermic liniments, inhalations, sprays, suppositories and pessaries for vaginal administration which comprise one or more of the active compound(s) and may be prepared by methods known per se.  
      Sprays may comprise additional substances other than diluents, such as stabilizing agents (such as sodium sulfate), isotonic buffers (such as sodium chloride, sodium citrate or citric acid). For preparation of such sprays, for example, the method described in the U.S. Pat. Nos. 2,868,691 or 3,095,355 may be used.
