Drugs containing triazaspiro[5.5]undecane derivatives as the active ingredient

TECHNICAL FIELD

[0001] The present invention relates to a pharmaceutical composition for prevention and/or treatment for human immnodeficiency virus (hereinafter referred to as “HIV”) infection or acquired immune deficiency syndrome (called AIDS) induced by the infection which comprises, as an active ingredient, at least one selected from triazaspiro[5.5]undecane derivatives, quaternary ammonium salts thereof and N-oxides thereof, and non-toxic salts thereof, and if necessary, other agents for prevention and/or treatment for HIV infection.

[0002] More particularly, it relates to a pharmaceutical composition for prevention and/or treatment for HIV infection or AIDS induced by the infection which comprises, as an active ingredient, at least one selected from triazaspiro[5.5]undecane derivatives represented by formula (I)

[0003] quaternary ammonium salts thereof or N-oxides thereof, or non-toxic salts thereof, and if necessary, a protease inhibitor, a reverse transcriptase inhibitor, a fusion inhibitor and/or a chemokine regulator.

BACKGROUND ART

[0004] In the publication of International Publication No. 01/40227, it is reported that the compounds represented by formula (I) regulate the effect of chemokine/chemokine receptor, so they are used for prevention and/or treatment of various inflammatory diseases, asthma, atopic dermatitis, urticaria, allergic diseases (allergic bronchopulmonary aspergillosis or allergic eosinophilic gastroenteritis etc.), nephritis, nephropathy, hepatitis, arthritis, rheumatoid arthritis, psoriasis, rhinitis, conjunctivitis, ischemic reperfusion disorder, multiple sclerosis, ulcerative colitis, acute respiratory distress syndrome, cytotoxic shock, diabetes, autoimmune disease, in transplanted organ rejection reactions, immunosuppression, cancer metastasis and acquired immune deficiency syndrome. Furthermore, in the specification, the inhibition effect on the binding of RANTES to CCR5 and the inhibition effect on the binding of MCP-1 to CCR2 had been found experimentally. However, the test which indicates that the compounds represented by formula (I) are used for actual HIV infection has never been described.

[0005] Furthermore, in the specification, a combination of chemokine/chemokine regulator with other drugs has never been described.

DISCLOSURE OF THE INVENTION

[0006] The present inventors have investigated, and consequently, the present inventors have found experimentally that triazaspiro[5.5]undecane derivatives represented by formula (I), quaternary salts thereof or N-oxides thereof, or non-toxic salts thereof have effect for HIV infection.

[0007] Furthermore, the present inventors have found that a combination of triazaspiro[5.5]undecane derivatives represented by formula (I), quaternary salts thereof or N-oxides thereof, or non-toxic salts thereof with at least one member of other preventive and/or treating agents for HIV infection has effect for HIV infection, too.

[0008] The present invention relates to

[0009] (1) A pharmaceutical composition for prevention and/or treatment for HIV infection which comprises, as an active ingredient, at least one triazaspiro[5.5]undecane derivative represented by formula (I)

[0305] (wherein R1-1A, R2-1A, R3-1A, R4-1A and R5-1A have the same meaning as R1-1, R2-1, R3-1, R4-1 and R5-1 respectively, wherein all of them are not a group containing carboxyl, hydroxy, amino or thiol, and the other symbol have the same meanings as defined hereinbefore.) may be prepared by the following methods.

[0306] Among the compounds of formula (I-1A), the compounds in which R1 does not represent hydrogen, i.e., the compounds of formula (I-1A-1)

[0309] (wherein T is C1-8 alkyl, C3-8 mono-carbocyclic ring or C1-8 alkyl substituted by C3-8 mono-carbocyclic ring.).

[0310] The cyclization of compounds of formula (II-1) is well known. For example, it may be carried out by heating in an organic solvent (toluene etc.) in the presence of acid (acetic acid, trifluoroacetic acid or hydrochloric acid etc.) at 60-120° C. This cyclization reaction is carried out with the cleavage from polystyrene resin.

[0311] If necessary, the conversion to desired non-toxic salts may be carried out by the conventional method in succession to this reaction.

[0312] The cyclization of compounds of formula (II-2) is well known. For example, it may be carried out by heating in an organic solvent (dichroloethane or toluene etc.), with tertiary amine (triethylamine or diisopropylethylamine etc.) at 60-120° C.

[0315] (wherein R1-1A-1-1 is an amino-protecting group, and the other symbols have the same meaning as defined hereinbefore.).

[0316] A protecting group of amino includes, for example, benzyl, benzyloxycarbonyl, allyloxycarbonyl, t-butoxycarbonyl or trifluoroacetyl etc.

[0317] The protecting group of amino includes the above one, in addition, the other protecting group which is removable selectively and easily, for example, one described in T. W. Greene et. al., Protective Groups in Organic Synthesis, Third Edition, Wiley-Interscience, New York, 1999.

[0319] (1) the alkaline hydrolysis,

[0320] (2) the removal of a protecting group in an acidic condition,

[0321] (3) the removal of a protecting group by hydrogenolysis or

[0322] (4) the removal of a protecting group using metal complex etc.

[0323] Concrete descriptions of these methods are as follows:

[0439] The compound of the present invention represented by formula (I), a quaternary ammonium salt thereof, an N-oxide thereof or a non-toxic salt thereof may be used together with at least one member of other preventive and/or treating agent(s) for HIV infection (particularly an agent for preventive and/or treating agent AIDS). In that case, the drug as such may be mixed with pharmacologically acceptable excipient, binder, disintegrating agent, lubricant, stabilizer, solubilizer, diluent, etc. either separately or simultaneously to make into a pharmaceutical preparation and that can be administered either orally or parenterally as a pharmaceutical composition for prevention and/or treatment of HIV infection.

[0440] The compound of the present invention represented by formula (I), a quaternary ammonium salt thereof, an N-oxide thereof or a non-toxic salt thereof has an infection inhibiting activity to HIV-I which acquired resistance to other agent for preventive and/or treating HIV infection (particularly, an agent for preventive and/or treating agent AIDS). Therefore, it is also able to be used for HIV-infected patients to whom other agent for preventive and/or treating HIV infection is no longer effective. In that case, although the compound of the present invention may be used solely, it may be also used together with an agent for preventive and/or treating HIV infection where infected HIV-1 strain acquired resistance or with other drugs.

[0441] The present invention covers the case where the compound represented by formula (I), a quaternary ammonium salt thereof, an N-oxide thereof or a non-toxic salt thereof is combined with a drug which does not inhibit the HIV infection whereby preventive and/or treating effect for HIV infection is enhanced as compared with a single preparation.

[3091] Inhibiting Activity to HIV-1 Infection to Human PBMC:

[3092] Human PBMC (peripheral blood mononuclear cell) was isolated from HIV-negative healthy persons by a Ficol-Hipaque density-gradient centrifugation and incubated for 3 days in the presence of 10 μg/ml PHA (phytohemagglutinin). PHA-stimulated PBMC was suspended in RPMI 1640 containing 10% serum to give a density of 1×105 cells/ml and poured into a 96-well microplate. Furthermore, in the presence of a sole test compound in various concentrations or in the co-presence with other anti-HIV inhibitor (such as AZT (zidovudin) or AMD 3100), various HIV-1 cell lines of 50 TCID50 (such as HIV-1LAI, HIV-1NL4-3, HIV-1BaL, HIV-1JRFL, HIV-189.6, HIV-1 HIV-1ERS104pre, HIV-1JSL, HIV-1MM, HIV-1TM and HIV-1MOKW) were exposed. After being incubated for 7 days, the amount of HIV-1 p24 antigen on the supernatant liquid of the incubation was measured by an EIA method using Lumipulse F (Fuji Rebio).

[3093] Inhibiting effect to HIV-1 infection to human PBMC was investigated by the joint use of the compound of Example 2(1) with AMD 3100. The compound of Example 2(1) in various concentrations and AMD 3100 were added either solely or combinably and an assay was carried out. Results of the compound of Example 2(1) to HIV-189.6 and to a mixed virus of HIV-1BaL and HIV-1NL4-3 are shown in Tables 1 and 2. Inhibiting effects of both compounds when the p24 amount where the compounds are not added is defined as 100% are shown in terms of % control.
