Definitions

  • the present invention relates to mimetics of sialyl-Lewis X and sialyl-Lewis A, in which, in the natural tetrasaccharide, the neuraminic acid residue is replaced by an S-configurated methyl substituted with one carboxyl residue and one other substituent and the N-acetyl- glucosamine residue is replaced by a non-glycosidic residue of a 1 ,2-diol, to processes for the preparation of these compounds and to the use of these mimetics in therapeutic methods.
  • the complex process of inflammation which takes place in several stages, is the body's natural reaction to injuries in which, for example, there is also invasion by infectious agents.
  • the endothelium which lines the blood vessels expresses adhesion proteins on its surface.

Abstract

Compounds of formula (I) in which X is the residue of a non-glycosidic aliphatic 1,2-diol; R1 is an S-configurated methyl substituted with one carboxyl residue and one other substituent; and R2 is hydrogen, C1-C12alkyl or C6aryl; as mimetics of sialyl-Lewis X and sialyl-Lewis A.

Description

Diqlvcosylated 1.2-diols as mimetics of sialyl-Lewis X and sialyl-Lewis A.
The present invention relates to mimetics of sialyl-Lewis X and sialyl-Lewis A, in which, in the natural tetrasaccharide, the neuraminic acid residue is replaced by an S-configurated methyl substituted with one carboxyl residue and one other substituent and the N-acetyl- glucosamine residue is replaced by a non-glycosidic residue of a 1 ,2-diol, to processes for the preparation of these compounds and to the use of these mimetics in therapeutic methods.
The complex process of inflammation, which takes place in several stages, is the body's natural reaction to injuries in which, for example, there is also invasion by infectious agents. Under the influence of cytokines, the endothelium which lines the blood vessels expresses adhesion proteins on its surface. The P and E selectins bring about, by a protein-carbo¬ hydrate interaction with glycolipids and glycoproteins on the leukocyte membrane, the so¬ called "rolling" of leukocytes. The latter are slowed down by this process, and there is acti¬ vation of certain proteins (integrins) on their surface which ensure firm adhesion of the leukocytes to the endothelium. This is followed by migration of the leukocytes into the damaged tissue.
When this process takes place in a controlled manner, the damage is eliminated after a certain time without major adverse effects remaining. It is otherwise in the case of certain acute and chronic inflammatory processes, in which the migration of leukocytes takes place in an uncontrolled manner, which leads to severe damage to the body. This is the case in disorders such as cardiogenic shock, myocardial infarct, thrombosis, rheumatism, psoriasis, dermatitis, acute respiratory distress syndrome and metastatic cancer [Dasgupta, F., Rao, B.N.N., Exp. Opin. Invest. Drugs 3:709-724 (1994)].
Several approaches to the development of medicaments which intervene at various points in these unwanted processes have already been pursued [Dasgupta, F., Rao, B.N.N., Exp. Opin. Invest. Drugs 3:709-724 (1994)]. The aim of one route is to prevent the interaction between P and E selectins and their receptors on the leukocyte membrane, thus to prevent the "rolling", by mimetics of the corresponding epitopes. This also results in suppression of the subsequent processes. One of the smallest carbohydrate epitopes as ligand for E selectin is sialyl-Lewis X [neuraminic acid-α(2→3)-galactose-β(1 →4)-(fucose-α(1->3))-N- acetylglucosamine (sLex)].
EP-A-0 579 196 proposed as compounds competing with the natural ligands for binding to E selectin mimetics of sLex in which the neuraminic acid residue is replaced by a lactic acid residue. WO 93/10796 describes compounds which comprise in place of the neuraminic acid residue the residue of an α-hydroxy acid. WO 93/23031 discloses mimetics in which the N-acetylglucosamine residue (GlcNAc residue) is replaced by an R,R-1 ,2-cyclohexane- dioxy. However, it is common to all these compounds that the binding affinity between them and the E selectin is increased only inconsiderably compared with that of sLex, or is in fact worse, and is insufficient for a therapeutic effect.
It has now been found, surprisingly, that simultaneous replacement of the neuraminic acid residue by an S-configurated methyl substituted with one carboxyl residue and one other substituent and of the N-acetylglucosamine residue by a non-glycosidic residue of an ali¬ phatic diol results in an unexpectedly high binding affinity of the resulting mimetic. The novel compounds additionally represent a structural and chemical simplification, have a lower molecular weight and can be obtained in larger quantities by methods with low syn¬ thetic complexity.

The present invention additionally relates to a process for the preparation of the compounds of the formula I which comprises etherifying the 3-OH group of a compound of the formula V
in which R2 and X have the abovementioned meanings, R12 is a protective group and Re' and Re" are, independently of one another, hydrogen or a protective group, with a compound of the formula VI
R,-R 13 (VI)
in which Ri has the abovementioned meaning and Re is a leaving group, and eliminating the protective groups. Leaving groups can be: halides, such as chloride, bromide and iodide, and sulfonic acids, for example trifluoromethanesulfonate, aliphatic, cycloaliphatic or aromatic sulfonic acids which are unsubstituted or substituted by d-C alkyl; d-C alkoxy, nitro, cyano or halogen (chlorine, bromine). Some examples of these acids are: methanesulfonic acid, mono-, di- or trifluoromethanesulfonic acids or p-nitrobenzenesulfonic acid. CF3-S02-0" (also referred to as triflate) is particularly preferably used. The leaving group is advantageously selected from the group consisting of halogen and unsubstituted and halogenated R-S02-, in which R is CrCealkyl, in particular d-C6alkyl, C5-C6cycloalkyl, phenyl, benzyl, Cι-Cι2alkylphenyl, in particular d-C4alkylphenyl, or Cι-d2alkylbenzyl, in particular d-C alkylbenzyl, for example methane, ethane, propane, butane, benzene, benzyl- and p-methylbenzenesul- fonyl. Preferred leaving groups are Cl, Br, I, -S02CF3 (triflate) and p-nitrobenzenesulfonyl, and -S02CF3 is particularly preferred.
The compounds of the formula VI are known in some cases or can be obtained by known processes, as described by Degerbeck et al. [Degerbeck, F., Fransson, B., Grehn, L., Ragnarsson, U., J. Chem. Soc. Perkin Trans. 1 :11-14 (1993)] and by Dureault et al. [Dureault, A., Tranchepain, I., Depezay, J.C, Synthesis 491-493 (1987)]. Optically pure compounds can be obtained by using optically pure starting compounds (e.g. amino acids, α-hydroxylic acids) or by chromatographic separation processes, for example with chiral solid phases.
The compounds of the formula V are novel and the invention likewise relates to them. They can be obtained by known glycosylation methods starting from known fucosyl and galacto- syl donors and diols of the formula HO-X-OH. Stepwise introduction of galactose and fucose or vice versa is advantageous.
For the preparation of the compounds of the formula V, firstly the pseudo-trisaccharide building blocks are synthesized. The pseudotrisaccharide is assembled either by glycosidic attachment for the activated and protected galactose onto the fucose-O-X-OH building block or by glycosidic attachment of suitably protected and activated fucose onto a galac- tose-O-X-OH building block. Glycosylation reactions are known on a large scale and are described in the specialist literature. It is then possible to introduce the group Ri into the pseudotrisaccharide. The resulting com¬ pounds of the formula I can subsequently be modified. This modification may comprise hydrogenation of aromatic compounds to cycloaliphatic groups, which can take place, for example, at the same time as the hydrogenolytic elimination of protective groups. It is furthermore possible for an amino group to be acylated and/or alkylated and/or sulfonated. The preparation of secondary and tertiary amines can be carried out by reductive amination.
It has proved advantageous to activate the 3-OH group of the galactose residue by etherifi¬ cation. Particularly suitable for this purpose are dialkyltin oxides, dialkyltin alkoxylates and bis(trialkyl)tin oxides. Some examples are dibutyltin oxide, dibutyltin(0-methyl)2 and (tributyl- tin)20. The activating agents are preferably used in stoichiometric amounts. In this case, the reaction is carried out in two stages, namely a) activation and b) coupling with the com¬ pounds of the formula VI.
The activation process can be carried out at temperatures from 40 to 200°C, preferably 60 to 120°C.
The compounds of the formula V and of the formula VI can be employed in equimolar amounts. However, it has proved expedient to employ the compounds of the formula VI in excess, for example in an amount which is up to 10 times, preferably up to 5 times, the amount of the compound of the formula V.
It is furthermore expedient to carry out the reaction in both reaction stages in the presence of an inert solvent or mixtures of solvents. Reactive protic solvents such as alkanols and, furthermore, acid amides are unsuitable in reaction stage b). It is possible to use non-polar aprotie and polar aprotie or polar protic solvents. These may be aliphatic or aromatic hydro¬ carbons such as pentane, hexane, cyclohexane, methylcyclohexane, benzene, toluene or xylene, halogenated hydrocarbons such as methylene chloride, chloroform, tetrachloro¬ methane, 1 ,2-dichloroethane, 1 ,1 ,2-trichloroethane, 1 ,1 ,2,2-tetrachloroethane and chloro¬ benzene, linear or cyclic ethers such as diethyl ether, dibutyl ether, ethylene glycol dimethyl or diethyl ether, tetrahydrofuran and dioxane, N,N-dialkylated carboxamides such as dimethylformamide, N-alkylated lactams such as N-methylpyrrolidone, ketones such as acetone and methyl isobutyl ketone, carboxylic esters such as methyl or ethyl acetate, or alkanols such as methanol, ethanol, propanol, butanol and ethylene glycol monoethyl ether. Particularly preferred solvents are methanol, ethanol, benzene and toluene.
Protective groups and processes for derivatizing hydroxyl groups with such protective groups are generally known in sugar and nucleotide chemistry and are described, for example, by Beaucage, S.L. Iyer, R., Tetrahedron 48:2223-2311 (1992). Examples of such protective groups are: benzyl, methylbenzyl, dimethylbenzyl, methoxybenzyl, dimethoxy- benzyl, bromobenzyl, 2,4-dichlorobenzyl; diphenylmethyl, di(methylphenyl)methyl, di(di- methylphenyl)methyl, di(methoxyphenyl)methyl, di(dimethoxyphenyl)methyl, triphenylmethyl, tris-4,4',4"-tert-butylphenylmethyl, di-p-anisylphenylmethyl, tri(methylphenyl)methyl, tri(dimethylphenyl)methyl, methoxyphenyl(diphenyl)methyl, di(methoxyphenyl)phenylmethyl, tri(methoxyphenyl)methyl, tri(dimethoxyphenyl)methyl; triphenylsilyl, alkyldiphenylsilyl, dialkylphenylsilyl and trialkylsilyl with 1 to 20, preferably 1 to 12, and particularly preferably 1 to 8 C atoms in the alkyl groups, for example triethylsilyl, tri-n-propylsilyl, i-propyl- dimethylsilyl, t-butyl-dimethylsilyl, t-butyl-diphenylsilyl, n-octyl-dimethylsilyl, (1 ,1 ,2,2-tetra- methylethyl)dimethylsilyl; C2-Ce-, in particular C2-C8acyl, such as acetyl, propanoyl, butan- oyl, pentanoyl, hexanoyl, benzoyl, methyl benzoyl, methoxybenzoyl, chlorobenzoyl and bromobenzoyl. The protective groups can be identical or different. Preferred protective groups are selected from the group consisting of linear and branched CrC8alkyl, in particu¬ lar d-dalkyl, for example methyl, ethyl, n- and i-propyl, n-, i- and t-butyl; C7-Cι2aralkyl, for example benzyl; trialkylsilyl with 3 to 20 C atoms, in particular 3 to 12 C atoms, for example triethylsilyl, tri-n-propylsilyl, tri-i-propylsilyl, i-propyl-dimethylsilyl, t-butyl-dimethylsilyl, t-butyl- diphenylsilyl, n-octyl-dimethylsilyl, (1 ,1 ,2,2-tetramethylethyl)dimethylsilyl; substituted methyli¬ dene groups which are obtainable by acetal or ketal formation from adjacent hydroxyl groups of the sugars or sugar derivatives with aldehydes and ketones, which preferably contain 2 to 12 or 3 to 12 C atoms, for example Crd2alkylidene, preferably Ci-Cealkylidene and in particular d-C alkylidene, such as ethylidene, 1 ,1- and 2,2-propylidene, 1 ,1- and 2,2-butylidene, benzylidene; unsubstituted and halogenated C2-Ceacyl, in particular C2-C8acyl, such as acetyl, propanoyl, butanoyl, pentanoyl, hexanoyl, pivaloyl and benzoyl.
The synthesis preferably takes place with protective groups for Re' and Re" which together form an alkylidene group with, preferably 1 to 12 and, more preferably 1 to 8 C atoms. In this connection, particularly preferred protective groups are those in which R12' and Re" to¬ gether are an alkylidene group with, in particular, 1 to 12 C atoms, with the alkylidene group forming an acetal or ketal with the oxygen atoms. These protective groups are ones which can be eliminated under neutral or weakly acidic conditions. Particularly suitable protective groups are acyl, benzyl, substituted benzyl, benzyloxymethyl, alkyl and silyl. R ' and Re" are, particularly preferably, together alkylidene, for example alkyl- or alkoxy- substituted benzylidene. Re' and Ri2" can, however, also be hydrogen, or one of Re' and Re" can be a protective group such as benzyl and the other one of Re' and Re" can be hydrogen.
Examples of protective carboxylate groups are alkoxy- and aralkoxycarbonyl groups, pre¬ ferably -C02Bn, -C02CH3.
The reaction for elimination of the protective groups is preferably carried out at a tempera¬ ture of 0°C to 50°C, and particular at room temperature.
Further details of the preparation of the compounds of the formula I are described in the examples.
An alternative synthetic route comprises glycosidic linkage of the protected fucose hydroxy ether of the formula VII
in which R2, Re and X have the abovementioned meanings, with the protected galactose of the formula VIII
in which Ri has the abovementioned meaning, Z is O or S, R12 is a protective group and R is a leaving group, and subsequent removal of the protective groups from the resulting com¬ pound.
It is possible to chose reaction conditions like those implemented for the process described previously. The leaving group R can be, for example, -C(=NH)-CCI3 or 4-pentenyl. The com¬ pounds of the formula VII can be obtained in a simple manner by glycosidic linkage of ap¬ propriately protected fucose with a compound of the formula HO-X-OH which is monopro¬ tected where appropriate. The compounds of the formula VIII can be obtained by etherifi¬ cation of compounds of the formula R1OH with galactose which is protected where appropri¬ ate.
The compounds according to the invention have antiinflammatory properties and can accordingly be used as medicaments. It is possible with them in particular to alleviate dis¬ orders such as cardiogenic shock, myocardial infarct, thrombosis, rheumatism, psoriasis, dermatitis, acute respiratory distress syndrome, asthma, arthritis and metastatic cancer. The invention furthermore relates to the compounds according to the invention for use in a therapeutic method for the treatment of disorders in warm-blooded animals, including humans. The dosage on administration to warm-blooded animals with a body weight of about 70 kg can be, for example, 0.01 to 1000 mg per day. Administration preferably takes place in the form of pharmaceutical compositions, parenterally, for example intravenously or intraperitoneally.
The invention furthermore relates to a pharmaceutical composition comprising an effective amount of the compound according to the invention, alone or together with other active sub¬ stances, a pharmaceutical carrier, preferably in a significant amount, and, where appropri¬ ate, excipients.
The pharmacologically active compounds according to the invention can be used in the form of compositions which can be administered parenterally or of infusion solutions. Solu¬ tions of this type are preferably isotonic aqueous solutions or suspensions, it being possible to prepare the latter, for example in the case of lyophilized compositions which comprise the active substance alone or together with a carrier, for example mannitol, before use. The pharmaceutical compositions can be sterilized and/or comprise excipients, for example pre- servatives, stabilizers, wetting agents and/or emulsifiers, solubilizers, salts to control the osmotic pressure and/or buffers. The pharmaceutical compositions, which may, if required, comprise other pharmacologically active substances such as antibiotics, are produced in a manner known per se, for example by conventional dissolving or lyophilizing processes, and comprise about 0.1 % to 90 %, in particular from about 0.5 % to about 30 %, for example 1 to 5 %, of active substance(s).

The solution is concentrated in vacuo and azeotroped first with ethanol and then with hexane, subsequently dried under high vacuum in order to remove remaining H20. The residue is mixed with N,N-dimethylform- amide (1.3 ml) and benzyl bromide (132 μl, 1.11 mmol) , and the mixture is stirred at room temperature for 75 minutes. Then further benzyl bromide (20 μl, 0.168 mmol) is added, and the mixture is stirred for a further 50 minutes. The white suspension is diluted with CH2CI2 (5 ml), filtered through HyfloSuperCel® and concentrated in vacuo. Purification of the crude product by flash chromatography on silica gel (eluent: ethyl acetate/hexane 4:1) affords benzyl (f?)- 2-hydroxy-4-phenylbutyrate 27 (0.21 g, 70 %). The product (0.3 g, 1.11 mmol) is dissolved in CH2CI2 (4.5 ml), 2,6-di-tetf-butylpyridine (323 μl, 1.44 mmol) is added, and the mixture is cooled to -20°C. Then trifluoromethanesulfonic anhydride (222 μl, 1.27 mmol) is added dropwise over the course of 3 minutes, and the solution is warmed to 0°C over the course of 45 minutes. After 75 minutes at 0°C, the mixture is diluted with CH2CI2 (20 ml) and washed with 1 molar aqueous KH2P0 solution (15 ml). The aqueous phase is extracted with CH2CI2 (2 x 10 ml), and the combined organic phases are washed with H20 (10 ml), dried (Na2S0 ), filtered and concentrated in vacuo. The residue is purified roughly by column filtration on silica gel (eluent: ethyl acetate/hexane 1 :9), resulting in the crude triflate A2 (0.311 g, 70 %) as an oil.

Chem. 38:1538-1546 (1995)] and of the acceptor 2 (3.44 g, 6.46 mmol) is dried under high vacuum for one hour. Then activated 4A molecular sieves (20 g) and DMTST (4.17 g, 16.14 mmol) are added under a nitrogen atmosphere, followed by CH2CI2 (70 ml). The yellowish suspen¬ sion is dried at room temperature and, after 3 hours, 5 ml of a suspension consisting of DMTST (5.84 g, 22.61 mmol), 4A molecular sieves (4.0 g) and CH2CI2 (35 ml) are added. Further 5 ml portions of this DMTST suspension are added after 30, 45 and 90 minutes respectively. The brown reaction mixture is then stirred for 15 hours, and thereafter filtered through Hyflo Super Cef (filter aid), washing with CH2CI2 (300 ml). The filtrate is extracted by shaking first with 10 % aqueous NaHC03 solution and then with saturated NaCl solution, and the organic phase is dried with Na2S04| filtered and concentrated in a vacuum rotary evaporator. The remaining brown foam is purified by two column chromatographies on silica gel (eluent for 1st chromatography: ethyl acetate/hexane 1 :4; 2nd chromatography: ethyl acetate/toluene 1 :9), resulting in the pure product 3 as a colourless solid (4.28 g, 60 %), which is immediately used further.
A solution of the tetrabenzoate 3 (3.38 g, 3.04 mmol) and sodium methoxide (0.165 g, 3.05 mmol) in dry methanol (32 ml) is stirred at room temperature for 3 hours. The mixture is neutralized by adding a strongly acidic ion exchanger (Amberlyst 15) and then filtered through Hyflo Super Cel®, washing with CH2CI2. The filtrate is concentrated in vacuo, and the remaining yellow oil is purified by flash chromatography on silica gel (elution: CH2CI2/ methanol 19:1), resulting in the pure tetrol 4 (1.95 g, 92 %).
A solution of the tetrol 4 (1.0 g, 1.44 mmol), benzaldehyde dimethyl acetal (430 ml, 2.86 mmol) and camphorsulfonic acid (0.1 g, 0.43 mmol) in acetonitrile (20 ml) is stirred at room temperature. After 4 hours, further camphorsulfonic acid (0.15 g, 0.65 mmol) is added and the mixture is stirred for a further 6 hours at room temperature, after which it is heated at 35°C for a further 6 hours. Then further camphorsulfonic acid (0.06 g, 0.26 mmol) is added, and the solution is stirred at room temperature for 6 hours. The reaction mixture is filtered through Hyflo Super Cel®, washing with ethyl acetate. The filtrate is extracted by shaking first with saturated aqueous NaHC03 solution and then with saturated NaCl solution, and the organic phase is dried (Na2S0 ), filtered and concentrated in vacuo, resul¬ ting in 1.5 g of crude product. Purification of the crude product by flash chromatography on silica gel (CH2CI2/MeOH 39:1) affords, besides the required benzylidene acetal 5 (0.475 g), a mixture of less polar byproducts (0.4 g).

After incubation 100 μl/well of 2 % BSA in Tris Ca++ buffer is added and incubated at room temperature for 1 hour. During incubation the compounds (2x serial dilution) are titrated in 1 % BSA in Tris-Ca++ using U-shaped low bind microtiter plates (Plate 2). The rows are serially diluted up to row 9. Rows 10, 11 , and 12 are just buffer. Final volume is 60 μl/well and the first well contains 10 mM of compound with the exception of the positive controls, A (SLeΑemieux) and B are used as positive controls for each plate and the first well contains 5 mM of these compounds. PolySLeaSA-HRP conjugate is prepared in advance by incubating Sialyl Lea-PAA-biotin (cat #01-044, GiycoTech Corp., Rockville, MD) with Streptavidin-HRP in a molar ratio of 1 :2. 60 μl/well of 1 ng/μl of polySLeaSA-HRP conjugate in 1 % BSA in Tris-Ca++ are added to all wells except row 11 in Plate 2. Plate 1 is washed four times with Tris-Ca++ in the automatic plate washer. 100 μl/well are transferred from Plate 2 to Plate 1 starting from lowest concentration of compound. Plate 2 is dis¬ carded. The plate is incubated while rocking at room temperature for 2 hours.
