BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to novel compounds, N,N'-Bis[4-[2,3,6-tri-O-sulfo-4-O-(2,3,4,6-tetra-O-sulfo-.alpha.(and .beta.)-D-glucopyranosyl)-.alpha.(and .beta.)-D-glucopyranosylthio or sulfinyl or sulfonyl]phenyl]alkyldiamides and alkyldiamines, the cation salts thereof, to their use as modulators of the complement system of warm-blooded animals, to the intermediates thereof and to the process for the preparation of such intermediates and end products.
2. Description of the Prior Art
The term "complement" refers to a complex group of proteins in body fluids that, working together with antibodies or other factors, play an important role as mediators of immune, allergic, immunochemical and/or immunopathological reactions. The reactions in which complement participates take place in blood serum or in other body fluids, and hence are considered to be humoral reactions.
With regard to human blood, there are at present more than 20 proteins in the complement system consisting of the so-called classical and alternative pathways. These complement proteins are generally designated by the letter C and by number: C1, C2, C3 and so on up to C9. The complement protein C1 is actually an assembly of subunits designated C1q, C1r and C1s. The numbers assigned to the complement proteins reflect the sequence in which they become active, with the exception of complement protein C4, which reacts after C1 and before C2. The numerical assignments for the proteins in the complement system were made before the reaction sequence was fully understood. A more detailed discussion of the complement system and its biochemical, biological and pathological role in the body processes can be found in, for example, Bull. W. H. O. 39: 935 (1968); Annu. Rev. Med. 19: 1 (1968); John Hopkins Med. J. 128: 57 (1971); Harvey Lect. 66: 75 (1972); N. Engl. J. Med. 287: 452, 489, 545, 592, 642 (1972); Sci. Am. 229 (5): 54 (1973); Fed. Pro. 32: 134 (1973); Med.

Dermatol. 4: 271 (1979); Infect. Dis. Rev. 1: 483 (1979).
The complement sysem (e.g., classical pathway) can be considered to consist of three subsystems: (1) a recognition unit (C1q) which enables it to combine with antibody molecules that have detected a foreign invader; (2) an activation unit (C1r, C1s, C2, C4, C3) which prepares a site on the neighboring membrane; and (3) an attack unit (C5, C6, C7, C8 and C9) which creates a "hole" in the membrane. The membrane attack unit is nonspecific; it destroys invaders only because it is generated in their neighborhood. In order to minimize damage to the host's own cells, its activity must be limited in time. This limitation is accomplished partly by the spontaneous decay of activated complement and partly by interference by inhibitors and destructive enzymes. The control of complement, however, is not perfect, and there are times when damage is done to host's cells. Immunity is, therefore, a double-edged sword.
Activation of the complement system also accelerates blood clotting. This action comes about by way of the complement-mediated release of a clotting factor from platelets. The biologically active complement fragments and complexes can become involved in reactions that damage the host's cells. These pathogenic reactions can result in the development of immune-complex diseases. For example, in some forms of nephritis, complement damages the basal membrane of the kidney, resulting in the escape of protein from the blood into the urine. The disease desseminated lupus erythematosus belongs in this category; its symptoms include nephritis, visceral lesions and skin eruptions. The treatment of diphtheria or tetanus with the injection of large amounts of antitoxin sometimes results in serum sickness, an immune-complex disease. Rheumatoid arthritis also involves immune complexes. Like disseminated lupus erythematosus. it is an autoimmune disease in which the disease symptoms are caused by pathological effects of the immune system in the host's tissues. In summary, the complement system has been shown to be involved with inflammation, coagulation, fibrinolysis, antibody-antigen reactions and other metabolic processes.
In the presence of antibody-antigen complexes the complement proteins are involved in a series of reactions which may lead to irreversible membrane damage if they occur in the vicinity of biological membranes. Thus, while complement constitutes a part of the body's defense mechanism against infection it also results in inflammation and tissue damage in the immunopathological process. The nature of certain complement proteins, suggestions regarding the mode of complement binding to biological membranes and the manner in which complement effects membrane damage are discussed in Annu. Rev. Biochem. 38: 389 (1969); J. Exp. Med. 141: 724 (1975); J. Immunol. 116: 1431 (1976); 119: 1, 1195, 1358, 1482 (1977); 120: 1841 (1978); Immunochemistry 115: 813 (1978); J. Biol. Chem. 254: 9908 (1979).
A variety of substances have been disclosed as inhibiting the complement system, i.e., as complement inhibitors. For example, the compounds, 3,3'-ureylenebis-[6-(2-amino-8-hydroxy-6-sulfo-1-naphthylazo)benzenesulfon ic acid], tetrasodium salt (chlorazol fast pink), heparin and a sulphated dextran have been reported to have an anticomplementary effect, Br. J. Exp. Pathol. 33: 327 (1952). German Patent No. 2,254,893 or South African Patent No. 727,923 discloses certain 1-(diphenylmethyl)-4-(3-phenylallyl)piperazines useful as complement inhibitors.

It has been reported that the known complement inhibitors, epsilon-aminocaproic acid and tranexamic acid, have been used with success in the treatment of hereditary angioneurotic edema, a disease state resulting from an inherited deficiency or lack of function of the serum inhibitor of the activated first component of complement (C1 inhibitor), N. Engl. J. Med. 286: 808 (1972); 287: 452 (1972); Ann. Intern. Med. 84: 580 (1976); J. Allergy Clin. Immunol. 60: 38 (1977).

Allergy Clin. Immunol. 65: 75 (1980).
It has also been reported that the drug pentosan-polysulfoester has an anticomplementary activity on human serum, both in vitro and in vivo, as judged by the reduction in total hemolytic complement activity, Pathol. Biol. 25: 33; 25 (2): 105; 25 (3): 179 (1977).

In the above Formulas I and II the sugar molecule is drawn to represent either maltose or cellobiose. This invention is not restricted to these two disaccharides, but instead is intended to include disaccharides consisting of aldohexoses, ketohexoses, aldopentoses and the like as well as oligosaccharides wherein the sugar units are 2-8 consisting of maltotrioses, maltotetraoses, maltopentaoses and the like.
The compounds of Formula I find utility as complement modulators in body fluids and as such may be used to ameliorate or prevent those pathological reactions requiring the function of complement and in the therapeutic treatment of warm-blooded animals having immunologic diseases such as rheumatoid arthritis, systemic lupus erythematosus, certain kinds of glomerulonephritis, certain kinds of autoallergic hemolytic anemia, certain kinds of platelet disorders and certain kinds of vasculitis. These compounds may also be used in the therapeutic treatment of warm-blooded animals having nonimmunologic diseases such as paroxysmal nocturnal hemoglobinurea, hereditary angioneurotic edema and inflammatory states induced by the action of bacterial or lysosomal enzymes on the appropriate complement components as, for example, inflammation following coronary occlusion. They also may be useful in the treatment of transplant rejection and ulcers and as blood culture and transport mediums. The sulfated compounds of this invention such as the sodium and aluminum salts, may be particularly useful in the treatment of ulcers and the like on oral therapy. Also, the non-sulfated intermediate compounds of Formula II may be useful as immuno-enhancing agents or potentiators.
The compounds of this invention may be prepared according to the following flowchart. ##STR3##
In accordance with the above flowchart, a brominated peracetyl sugar (1) is reacted with a p-nitrothio phenol (2), and sodium hydride in a solvent such as dimethoxyethane under an inert atmosphere for several hours, giving a 4-nitrophenyl 2,3,6-tri-O-acetyl-4-O-(2,3,4,6-tetra-O-acetyl-.alpha.(or .beta.)-D-glucopyranosyl)-1-thio-.alpha.(or .beta.)-D-glucopyranoside (3) which is then catalytically reduced to the corresponding 4-aminophenyl derivative (4). Alternatively, similar reaction of (1) with p-aminothiophenol (5) produces (4) directly without requiring reduction. The derivative (4) is then treated with an acid chloride (6) where X is, for example, COCl or SO.sub.2 Cl; Z is --(CH.sub.2).sub.m -- and m is an integer 0-12 in a solvent such as acetonitrile under an inert atmosphere for several hours giving a N,N'-bis[4-[2,3,6-tri-O-acetyl-4-O-(2,3,4,6-tetra-O-acetyl-.alpha.(or .beta.)-D-glucopyranosyl)-.alpha.(or .beta.)-D-glucopyranosylthio]phenyl]alkyldiamide (7), where Z is as described above and B is, for example, --NHCO--. The derivative (7) is then reacted with ammonia-saturated methanol at -5.degree. to +5.degree. C. under an inert atmosphere or with sodium in methanol for several hours giving a N,N'-bis[4-[4-O-(.alpha.(or .beta.)-D-glucopyranosyl)-.alpha.(or .beta.)-D-glucopyranosylthio]phenyl]alkyldiamide (8) where B and Z are as described above. The derivative (7) may also be reduced with diborane in dry tetrahydrofuran under an inert atmosphere at -5.degree. to +5.degree. C., giving the derivative (8) where Z is as described above and B is --NHCH.sub.2 --. Derivative (8) is then reacted with triethylamine-sulfur trioxide complex in N,N-dimethylacetamide, under an inert atmosphere at 60.degree.-65.degree. C. for several hours, giving the tetradecatriethylammonium derivative (9), where Y is NH.sup.+ (C.sub.2 H.sub.5).sub.3 which is then, if desired, reacted with a cation-containing compound wherein the salt forming moiety is selected from the group consisting of alkali metal, alkaline earth metal, aluminum, ammonia and substituted ammonia selected from the group consisting of piperidine, pyrazine, alkanolamine (C.sub.2 -C.sub. 6) and cycloalkylamine (C.sub.3 -C.sub.6), and thereafter precipitated in ethanol, giving the end product (10) of this invention.
It is generally preferred that the respective product of each process step, described hereinabove, is separated and/or isolated prior to its use as starting material for subsequent steps. Separation and isolation can be effected by any suitable purification procedure such as, evaporation, crystallization, column chromatography, thin-layer chromatography, distillation, etc. Also it should be appreciated that when typical reaction conditions (e.g., temperatures, mole ratios, reaction times) have been given, the conditions which are both above and below these specified ranges can also be used, though generally less conveniently.
The term "pharmaceutically acceptable salts" refers to those salts of the parent compound which do not significantly or adversely affect the pharmaceutical properties (e.g., toxicity, effectiveness, etc.) of the parent compound. The salt forming moieties of the present invention which are pharmaceutically acceptable include the alkali metals (e.g., sodium, potassium, etc.); alkaline earth metals (e.g., calcium, etc.); aluminum; ammonia; and substituted ammonia selected from the group consisting of trialkylamine (C.sub.1 -C.sub.6), piperidine, pyrazine, alkanolamine (C.sub.2 -C.sub.6) and cycloalkylamine (C.sub.3 -C.sub.6).

The compounds of the present invention may be administered internally, e.g., orally, intra-articularly or parenterally, to a warm-blooded animal to inhibit complement in the body fluid of the animal, such inhibition being useful in the amelioration or prevention of those reactions dependent upon the function of complement, such as inflammatory process and cell membrane damage induced by antigen-antibody complexes. A range of doses may be employed depending on the mode of administration, the condition being treated and the particular compound being used. For example, for intravenous or subcutaneous use from about 5 to about 50 mg/kg/day, or every six hours for more rapidly excreted salts, may be used. For intra-articular use for large joints such as the knee, from about 2 to about 20 mg/joint/week may be used, with proportionally smaller doses for smaller joints. The dosage range is to be adjusted to provide optimum therapeutic response in the warm-blooded animal being treated. In general, the amount of compound administered can vary over a wide range to provide from about 5 mg/kg to about 100 mg/kg of body weight of animal per day. The usual daily dosage for a 70 kg subject may vary from about 350 mg to about 3.5 g. Unit doses of the acid or salt can contain from about 0.5 mg to about 500 mg.
The compounds of the present invention may also be administered topically in the form of ointments, creams, lotions and the like, suitable for the treatment of complement dependent dermatological disorders.
Moreover, the compounds of the present invention may be administered in the form of dental pastes, ointments, buccal tablets and other compositions suitable for application periodontally for the treatment of periodontitis and related diseases of the oral cavity.
In therapeutic use, the compounds of this invention may be administered in the form of conventional pharmaceutical compositions. Such compositions may be formulated so as to be suitable for oral or parenteral administration. The active ingredient may be combined in admixture with a pharmaceutically acceptable carrier, which carrier may take a wide variety of forms depending on the form of preparation desired for administration, i.e., oral or parenteral. The compounds can be used in compositions such as tablets. Here, the principal active ingredient is mixed with conventional tabletting ingredients such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate, gums, or similar materials as nontoxic pharmaceutically acceptable diluents or carriers. The tablets or pills of the novel compositions can be laminated or otherwise compounded to provide a dosage form affording the advantage of prolonged or delayed action or predetermined successive action of the enclosed medication. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permits the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids or mixtures of polymeric acids with such materials as shellac, shellac and cetyl alcohol, cellulose acetate and the like. A particularly advantageous enteric coating comprises a styrene maleic acid copolymer together with known materials contributing to the enteric properties of the coating. The tablet or pill may be colored through the use of an appropriate nontoxic dye, so as to provide a pleasing appearance.
The liquid forms in which the novel compositions of the present invention may be incorporated for administration include suitable flavored emulsions with edible oils, such as, cottonseed oil, sesame oil, coconut oil, peanut oil, and the like, as well as elixirs and similar pharmaceutical vehicles. Sterile suspensions or solutions can be prepared for parenteral use. Isotonic preparations containing suitable preservatives are also desirable for injection use.
The term "dosage form," as described herein, refers to physically discrete units suitable as unitary dosage for warm-blooded animal subjects, each unit containing a predetermined quantity of active component calculated to produce the desired therapeutic effect in association with the required pharmaceutical diluent, carrier or vehicle. The specification for the novel dosage forms of this invention are indicated by characteristics of the active component and the particular therapeutic effect to be achieved or the limitations inherent in the art of compounding such an active component for therapeutic use in warm-blooded animals as disclosed in this specification. Examples of suitable oral dosage forms in accord with this invention are tablets, capsules, pills, powder packets, granules, wafers, cachets, teaspoonfuls, dropperfuls, ampules, vials, segregated multiples of any of the foregoing and other forms as herein described.
The complement inhibiting activity of the compounds of this invention has been demonstrated by one or more of the following identified tests: (i) Test Code 026 (C1 inhibitor)--This test measures the ability of activated human C1 to destroy fluid phase human C2 in the presence of C4 and appropriate dilutions of the test compound. An active inhibitor protects C2 from C1 and C4; (ii) Test Code 035 (C3-C9 inhibitor)--This test determines the ability of the late components of human complement (C3-C9) to lyse EAC 142 in the presence of appropriate dilutions of the test compound. An active inhibitor protects EAC 142 from lysis by human C3-C9; (iii) Cap 50 Test--Here, appropriate amounts of the test compound are added to a pool of guinea pig (or human) serum in vitro, after which the undiluted serum capillary tube assay of U.S. Pat. No. 3,876,376 is run. The concentration of compound inhibiting 50% is reported; and (iv) Guinea Pig Intraperitoneal Test (GPIP)--Guinea pigs weighing about 300 g are dosed intraperitoneally (i.p.) with 200 mg/kg of the test compound dissolved in saline and adjusted to pH 7-8. Approximately 0.4 ml blood samples, taken by orbital sinus puncture 2 hours and 6 hours after injections, are collected directly into centrifuge tubes; 5 ml blood samples, taken by decapitation 24 hours after injection, are collected directly into beakers. The samples are allowed to clot, centrifuged, and the resultant sera are assayed for complement activity using the capillary complement assay. Percent inhibition is calculated by comparison with simultaneous controls. The results of the GPIP appear in Table IV together with results of Test Code 026, 035, and Cap 50. Table IV shows that the principal compounds of the invention possess highly significant complement modulating activity in warm-blooded animals.
