Examples which may be mentioned are the 1 ,4-piperidinylene, 1 ,4-piperazinylene, 2,5-pyrrolidinylene, 4,2-imidazolidin- ylene and preferably the 4,1-piperidinylene radicals. Preferred meanings of the groups X1 and X2 are amino, aminocarbonyl, amidino and guanidino. By definition, the groups Z1 and Z2 are located between the groups B9 and B1 1 (-B9-Z1-B11-) and B10 and B12 (-B10-Z2-B12-), respectively. Accordingly, in the divalent groupings mentioned by way of example (for example 2,6-indolylene), the first number indicates the point of attachment to the group B9 and B10, respectively, and the second number indicates the point of attachment to the group B11 and B12, respectively. The definitions of M, A3, A4, X1 and X2 contain chemical formulae, such as, for example, Here, bonds which are unattached on one side mean that the building block is attached at this site to the remainder of the molecule. Bonds which are unattached on both sides mean that this building block has a plurality of sites via which the building block can be attached to the remainder of the molecule. In the context of this application, the term "terminal nitrogen atom" means in each case a nitrogen atom in the groups designated X1 , X2, Y1 and Y2. If the group X1 or X2 contains only one nitrogen atom, this nitrogen atom is the terminal nitrogen atom. If the group X1 or X2 contains a plurality of nitrogen atoms, the nitrogen atom which is furthest from the atom by means of which the bond to the group B9 (B11 ) or B10 (B12) is established is the terminal nitrogen atom. If the group Y1 or Y2 contains only one ring nitrogen atom, this ring nitrogen atom is the terminal nitrogen atom. If the group Y1 or Y2 contains a plurality of ring nitrogen atoms, the ring nitrogen atom which is furthest from the atom by means of which the bond to the group B9 or B10 is established is the terminal nitrogen atom. According to the invention, the direct route between the nitrogen atoms which act as terminal nitrogen atoms in the groups defined as X1 (Y1 ) or X2 (Y2) is considered to be the number of bonds which is obtained by counting the bonds which represent the shortest possible connection between the terminal nitrogen atoms. The following example is meant to illustrate the determination of the number of bonds on the direct route between two terminal nitrogen atoms: Here, the direct route comprises 34 bonds. Suitable salts for compounds of the formula I - depending on substitution - are all acid addition salts or all salts with bases. Particular mention may be made of the pharmacologically acceptable salts of inorganic and organic acids customarily used in pharmacy. Those suitable are, on the one hand, water- soluble and water-insoluble acid addition salts with acids such as, for example, hydrochloric acid, hydrobromic acid, phosphoric acid, nitric acid, sulfuric acid, acetic acid, citric acid, D-gluconic acid, benzoic acid, 2-(4-hydroxybenzoyl)benzoic acid, butyric acid, sulfosalicylic acid, maleic acid, lauric acid, malic acid, fumaric acid, succinic acid, oxalic acid, tartaric acid, embonic acid, stearic acid, toluenesulfonic acid, methanesulfonic acid or 3-hydroxy-2-naphthoic acid, where the acids are employed in salt preparation - depending on whether a mono- or polybasic acid is concerned and depending on which salt is desired - in an equimolar quantitative ratio or one differing therefrom. On the other hand, salts with bases are also suitable. Examples of salts with bases which may be mentioned are alkali metal (lithium, sodium, potassium) or calcium, aluminum, magnesium, titanium, ammonium, meglumine or guanidinium salts, where here too the bases are employed in salt preparation in an equimolar quantitative ratio or one differing therefrom. Pharmacologically unacceptable salts which can be obtained initially as process products, for example in the preparation of the compounds according to the invention on an industrial scale, are converted into pharmacologically acceptable salts by processes known to the person skilled in the art. It is known to the person skilled in the art that the compounds according to the invention, and also their salts, may contain varying amounts of solvents, for example when they are isolated in crystalline form.

The compounds of the formula I are constructed from a large number of divalent building blocks (M, A1 , A2, A3, A4, A5, A6, B1 , B2, B3, B4, B5, B6, B7, B8, B9, B10, B11 , B12, Z1 and Z2). In principle, they can be synthesized starting with any of these building blocks. If the compounds of the formula I are constructed largely symmetrically, it is favorable to start the synthesis with the central building block M, whereas in the case of predominantly asymmetrical compounds of the formula I a synthesis starting with one of the end groups K1 or K2 may be advantageous. Here, the building blocks are linked using always the same pattern, known per se to the person skilled in the art. It is known to the person skilled in the art that the compounds of the formula I can either be synthesized building block by building block, or by initially constructing relatively large fragments consisting of several individual building blocks, which can then be joined to give the complete molecule. Owing to the meanings which the individual building blocks of the compounds of the formula I can assume, amino [-NH-], ether [-0-], thioether [-S-], keto [-C(O)-], sulfonyl [-S(0) 2 -], ester [-O-C(O)-, -C(0)-0-], amide [-C(0)-NH-, -NH-C(O)-], sulfonamide [-S0 2 -NH-, -NH-S0 2 -], carbamate [-NH-C(0)-0-, -0-C(0)-NH-], carbamide [-NH-C(0)-NH-] or carbonate bridges [-0-C(0)-0-] are present in the compounds of the formula I. How to prepare such bridges is known per se to the person skilled in the art; suitable methods and starting materials for their preparation are described, for example, in March, Advanced Organic Chemistry, Reactions, Mechanisms and Structure, Third Edition, 1985, John Wiley & Sons. Ether and thioether bridges can be prepared, for example, by the method of Williamson. Keto bridges can be introduced, for example, as a component of relatively large building blocks, such as, for example, 1 ,3-dichloroacetone. Sulfonyl bridges can be obtained, for example, by oxidation of thioether bridges. There is a large number of known methods for preparing ester bridges. An example which may be mentioned here is the reaction of acids with alcohols, preferably using H 2 S0 4 or p-toluenesulfonic acid as catalyst; or with addition of a dehydrating agent, such as, for example, molecular sieve or a carbodiimide. Furthermore, the reaction of acyl chlorides with alcohols may be mentioned here. There is also a large number of known methods for preparing amide bridges. An example which may be mentioned here is the reaction of acyl chlorides with primary or secondary amines. Furthermore, reference is also made to all the methods which have been developed for peptide chemistry. Accordingly, it is possible to construct sulfonamide bridges from sulfonyl chlorides and primary or secondary amines. Carbamate bridges can be prepared, for example, by reacting chloroformates with amines. The chloro- formates for their part can be synthesized from alcohols and phosgene. A further variant for constructing carbamate bridges is the addition of alcohols to isocyanates. Similarly to the carbamate bridges, it is possible to prepare carbonate bridges starting from chloroformates, by reaction with alcohols (instead of amines). Carbamide bridges can be prepared, for example, by reacting isocyanates with amines. The preparation of compounds of the formula I may be shown in an exemplary manner using the reaction scheme below. Other compounds of the formula I can be prepared analogously, or by using the abovementioned methods known per se to the person skilled in the art. Reaction scheme 1 : Reaction scheme 1 shows an example of the synthesis of a compound of the formula I. It is also possible to convert compounds of the formula I by derivatization into other compounds of the formula I. Thus, for example, compounds of the formula I having a nitrogen-containing heteroaryl, heteroarylene, heterocycloalkyl or heterocycloalkylene building block can be converted by oxidation into the corresponding N-oxides. The N-oxidation is carried out in a manner which is likewise known to the person skilled in the art, for example using hydrogen peroxide in methanol or m-chloroperoxybenzoic acid in dichloromethane at room temperature. Which reaction conditions are required in the particular case for carrying out the process is known to the person skilled in the art owing to his expert knowledge. It is furthermore known to the person skilled in the art that if there are a number of reactive centers on a starting material or intermediate, it may be necessary to block one or more reactive centers temporarily by protective groups in order to allow a reaction to proceed specifically at the desired reaction center. A detailed description of the use of a large number of proven protective groups is found, for example, in T.W. Greene, Protective Groups in Organic Synthesis, John Wiley & Sons, 1991. The isolation and purification of the substances according to the invention is carried out in a manner known per se, for example by distilling off the solvent under reduced pressure and recrystallizing the resulting residue from a suitable solvent or subjecting it to one of the customary purification methods, such as, for example, column chromatography on a suitable support material. Salts are obtained by dissolving the free compound in a suitable solvent (for example a ketone, such as acetone, methyl ethyl ketone or methyl isobutyl ketone, an ether, such as diethyl ether, tetrahydro- furan or dioxane, a chlorinated hydrocarbon, such as methylene chloride or chloroform, or a low-molecular-weight aliphatic alcohol, such as ethanol or isopropanol) which contains the desired acid or base, or to which the desired acid or base is then added. The salts are obtained by filtering, reprecipitating, precipitating with a nonsolvent for the addition salt or by evaporating the solvent. Salts obtained can be converted by alkalization or by acidification into the free compounds, which in turn can be converted into salts. In this way, pharmacologically unacceptable salts can be converted into pharmacologically acceptable salts. The examples below serve to illustrate the invention in more detail without restricting it. Likewise, further compounds of the formula I, whose preparation is not explicitly described, can be prepared in an analogous manner or in a manner familiar per se to the person skilled in the art using customary process techniques. In the examples below, the abbreviation RT stands for room temperature, h for hours, min. for minutes, DMF for dimethylformamide and HBTU for 0-(benzotriazol-1-yl)-N,N,N',N'-tetramethyiuronium hexa- fluorophosphate. The compounds mentioned in the examples and their salts are the preferred subject of the invention. Examples End products: 1. 1,5-Bis-{2-[4-(4-aminomethylbenzylaminocarbonyl)piperazin-1-yl]-2-oxoethyl}perhydro- 1 ,5-diazocin-2,6-dione dihydrochloride 0.2 g of 1 ,5-bis-{2-[4-(4-tert-butyloxycarbonylaminomethylbenzylaminocarbonyl)piperazin-1-yl]-2-oxo- ethyl}-perhydro-1 ,5-diazocin-2,6-dione (starting material A1 ) is suspended in 2 ml of dichloromethane and then admixed with 2 ml of trifluoroacetic acid.

Commercial utility As tryptase inhibitors, the compounds according to the invention have useful pharmacological properties which make them commercially utilizable. Human tryptase is a serine protease which is the main protein in human mast cells. Tryptase comprises eight closely related enzymes ( 1 , α2, β1a, β1 b, β2, β3, mMCP-7-like-1 , mMCP-7-like-2; 85 to 99% sequence identity) (cf. Miller et al., J. Clin. Invest. 84 (1989) 1188-1195; Miller et al., J. Clin. Invest. 86 (1990) 864-870; Vanderslice et al., Proc. Natl. Acad. Sci., USA 87 (1990) 3811-3815; Pallaoro et al., J. Biol. Chem. 274 (1999) 3355-3362). However, only the β-tryptases (Schwartz et al., J. Clin. Invest. 96 (1995) 2702-2710; Sakai et al., J. Clin. Invest. 97 (1996) 988-995) are activated intracellularly and stored in catalytically active form in secretory granules. Compared with other known serine proteases, such as, for example, trypsin or chymotrypsin, tryptase has some special properties (Schwartz et al., Methods Enzymol. 244, (1994), 88-100; G. H. Caughey, „Mast cell proteases in immunology and biology". Marcel Dekker, Inc., New York, 1995). Tryptase from human tissue has a noncovalently-linked tetrameric structure which has to be stabilized by heparin or other proteoglycanes to be proteolytically active. Together with other inflammatory mediators, such as, for example, histamine and proteoglycanes, tryptase is released when human mast cells are activated. Because of this, tryptase is thought to play a role in a number of disorders, in particular in allergic and inflammatory disorders, firstly because of the importance of the mast cells in such disorders and secondly since an increased tryptase concentration was observed in a number of disorders of this type. Thus, tryptase is associated, inter alia, with the following diseases: acute and chronic (in particular inflammatory and allergen-induced) airway disorders of various origins (for example bronchitis, allergic bronchitis, bronchial asthma, COPD); interstitial lung disorders; disorders based on allergic reactions of the upper airways, (pharynx, nose) and the adjacent regions (for example paranasal sinuses, conjunctivae), such as, for example allergic conjunctivitis and allergic rhinitis; disorders of the arthritis type (for example rheumatoid arthritis); autoimmune disorders, such as multiple sclerosis; furthermore periodontitis, anaphylaxis, interstitial cystitis, dermatitis, psoriasis, sclerodermia/systemic sclerosis, inflammatory intestinal disorders (Crohn's disease, inflammatory bowel disease) and others. In particular, tryptase seems to be connected directly to the pathogenesis of asthma (Caughey, Am. J. Respir. Cell Mol. Biol. 16 (1997), 621-628; R. Tanaka, "The role of tryptase in allergic inflammation" in: Protease Inhibitors, IBC Library Series, 1979, Chapter 3.3.1-3.3.23). A further subject of the invention relates to the compounds according to the invention for use in the treatment and/or prophylaxis of diseases, in particular the diseases mentioned. The invention likewise relates to the use of the compounds according to the invention for preparing medicaments which are employed for the treatment and/or prophylaxis of the diseases mentioned. Medicaments for the treatment and/or prophylaxis of the diseases mentioned, which contain one or more of the compounds according to the invention, are furthermore a subject of the invention. The medicaments are prepared by processes which are known per se and familiar to the person skilled in the art. As medicaments, the compounds according to the invention (= active compounds) are either employed as such, or preferably in combination with suitable pharmaceutical excipients, for example in the form of tablets, coated tablets, capsules, suppositories, patches, emulsions, suspension, gels or solutions, the active compound content advantageously being between 0.1 and 95%. The person skilled in the art is familiar on the basis of his/her expert knowledge with the excipients which are suitable for the desired pharmaceutical formulations. In addition to solvents, gel-forming agents, ointment bases and other active compound vehicles, it is possible to use, for example, antioxi- dants, dispersants, emulsifiers, preservatives, solubilizers or permeation promoters. For the treatment of disorders of the respiratory tract, the compounds according to the invention are preferably also administered by inhalation. For this purpose, they are either administered directly as a powder (preferably in micronized form) or by nebulization of solutions or suspensions which contain them. With respect to the preparations and administration forms, reference is made, for example, to the details in European Patent 163 965. For the treatment of dermatoses, the compounds according to the invention are in particular used in the form of those medicaments which are suitable for topical administration. For the preparation of the medicaments, the compounds according to the invention (= active compounds) are preferably mixed with suitable pharmaceutical excipients and further processed to give suitable pharmaceutical formulations. Suitable pharmaceutical formulations which may be mentioned are, for example, powders, emulsions, suspensions, sprays, oils, ointments, fatty ointments, creams, pastes, gels or solutions. The medicaments according to the invention are prepared by processes known per se. The dosage of the active compounds in the case of systemic therapy (p.o. or i.v.) is between 0.1 and 10 mg per kilogram per day. Biological investigations The documented pathophysiological effects of mast cell tryptase are caused directly by the enzymatic activity of the protease. Accordingly, they are reduced or blocked by inhibitors which inhibit the enzymatic activity of the tryptase. A suitable measure for the affinity of a reversible inhibitor to the target protease is the equilibrium dissociation constant K, of the enzyme-inhibitor complex. This K, value can be determined via the effect of the inhibitor on the tryptase-induced cleavage of a chromogenic peptide-p-nitroanilide substrate or a fluorogenic peptide-aminomethylcoumarin substrate. Methodology The dissociation constants for the tryptase-inhibitor complexes are determined under equilibrium conditions in accordance with the general proposals of Bieth (Bieth JG, Pathophysiological Interpretation of kinetic constants of protease inhibitors, Bull. Europ. Physiopath. Resp. 16:183-195, 1980) and the methods of Sommerhoff et al. (Sommerhoff CP et al., A Kazal-type inhibitor of human mast cell tryptase: Isolation from the medical leech Hirudo medicinalis, characterization, and sequence analysis, Biol. Chem. Hoppe-Seyler 375: 685-694, 1994). Human tryptase is isolated from lung tissue or prepared recombinantly; the specific activity of the protease, determined by titration, is usually greater than 85% of the theoretical value. In the presence of heparin (0.1-50 μg/ml) for stabilizing the protease, constant amounts of the tryptase are incubated with increasing amounts of the inhibitors. After an equilibrium between the reaction partners has formed, the remaining enzyme activity after addition of the peptide-p-nitroanilide substrate tos-Gly-Pro- arg-pNA is determined and the cleavage of the latter is monitored at 405 nm for 3 min. Alternatively, the remaining enzymatic activity can also be determined using fluorogenic substrates. The apparent dissociation constants K ιapp (i.e. in the presence of substrate) are subsequently determined by adapting the enzyme rates to the general equation for reversible inhibitors (Morrison JF, Kinetics of the reversible inhibition of enzyme-catalyzed reactions by tight-binding inhibitors, Biochim. Biophys. Acta 185, 269-286, 1969) using non-linear regression: Vo = 1 - {E,+l,+K, app -[(E t +l,+K ιapp ) 2 -4E,IJ 1 2 }/2E, V| and V 0 are the rates in the presence and absence, respectively, of the inhibitor, and E t and l t are the tryptase and inhibitor concentrations, respectively. The apparent dissociation constants determined for the compounds according to the invention are shown in Table A below, where the numbers of the compounds correspond to the numbers of the compounds in the examples.
