Description
WO 2011/138365 PCT/EP2011/057130 Process for the Preparation of Bimosiamose 5 The present invention relates to a novel process for the preparation of the pharmaceutical compound 1,6-bis-[3-(3-carboxymethylphenyl)-4-(2-a-D-mannopyranosyloxy)-phenyl] hexane (also called Bimosiamose). By this process, Bimosiamose can be prepared in bigger quantities and in an improved manner with improved overall yield as compared to the methods of the prior art. This new method also allows for the technical production of Bimosiamose in a 10 selective crystal form (polymorph) and in an industrial scale. The structure of the drug compound 1,6-bis-[3-(3-carboxymethylphenyl)-4-(2-a-D mannopyranosyloxy)-phenyl]-hexane (Bimosiamose or the compound of the formula (I)) is described in US 5 919 768 and US 5 712 387; by I. Scott et al., Carbohydrate Research 317 15 (1-4), 1999, 210-216; by T. Kogan et al., J. Medicinal Chemistry 41(7), 1998, 1099-1111 and in EP-A 0 840 606. The compound of formula (I) has many valuable pharmacological properties. Bimosiamose acts as a pan-selectin antagonist and inhibits the leukocyte extravasation. As leukocyte extravasation is a key step in the pathogenesis of many inflammatory disorders or conditions, the compound of formula (I) offers the opportunity 20 to be used in a variety of inflammatory and micro-inflammatory indications and conditions. The compound Bimosiamose of formula (I) has ten chiral centers and can be used for the prophylaxis, treatment and diagnosis of inflammatory disorders and for the treatment and 25 prophylaxis of cosmetic and dermatological conditions where micro-inflammatory conditions are involved. O O H O OH 0 0 HO,,. O HO,,. O OH OH WO 2011/138365 PCT/EP2011/057130 -2 The compound of formula (I) may also be administered to treat other diseases that are associated with cell-cell adhesion. As the compound of formula (I) modulates the binding of E-selectin or P-selectin or L-selectin, many disease that are related to this interaction may be treated by the modulation of this binding interaction. The compound of formula (I) 5 is also useful for the treatment, diagnosis, and prophylaxis of several forms of cancer, including lung and colon cancer, for instance. Furthermore, the compound of formula (I) can be used for the treatment, diagnosis, and prophylaxis of diseases or conditions, in which selectin mediated leukocyte retention is involved, e.g. in lung diseases [D. Bock et al., Curr. Respir. Med. Rev., 2006, 2, 339-354]. The compound of formula (I) and its 10 physiologically tolerable salts are suitable as active pharmaceutical ingredients (API) for the prevention, treatment, and diagnosis of various inflammatory or micro-inflammatory diseases or conditions. The compound of formula (I) and/or its physiologically tolerable salts are preferably employed for this in the form of pharmaceutical preparations which are tailored with respect to their composition and the dosage form to the medicinal effects desired in the specific 15 case. For example, Bimosiamose can be used in the form of (a) solid preparations such as tablets (e.g. compressed, layered, sugar, film or enteric coated, chewable, delayed or extended release, sublingual, buccal or effervescent) or capsules (e.g. hard filled or soft gelatine) or in the form 20 of (b) liquid preparations such as oral solutions, emulsions and suspensions, parenteral solutions e.g. for injections and infusions, including lyophilized powders and ready-to-use injections, or ophthalmic solutionsor in the form of (c) semi-solid formulations for topical administration such as ointments, creams, gels, or mircoemulsions. In addition, specialized formulations of Bimosiamose, like liposomes and related forms, micellar solutions, 25 microspheres, nanoparticles or therapeutic systems, e.g. transdermal therapeutic systems, implants or pumps, inhalative dosage forms, biodegradable or bioerodible polymer systems, surgical or edible foams, soft or hydro gels, microsponges, are also suitable dosage forms. Furthermore the compound of formula (I) may be used for treating ageing of the skin caused by extrinsic and intrinsic factors. The signs of skin ageing are defined by the 30 appearance of wrinkles and fine lines, by the yellowing of the skin which develops a wizened appearance along with the appearance of pigmentation blemishes, by a change in the thickness of the skin, generally resulting in a thickening of the stratum corneum and of the epidermis and a thinning of the dermis, by disorganization of the elastin and collagen fibers which causes a loss of elasticity, of suppleness and of firmness, and by the 35 appearance of telangiectasia.
WO 2011/138365 PCT/EP2011/057130 -3 Various ways of synthesis for Bimosiamose are known, see e. g. T. Kogan et al., J. Medicinal Chemistry 41(7), 1998, 1099-1111 or US 5 919 768 or US 5 712 387. However, the overall yield of the known processes is rather low (2 to 3%). Furthermore, it turned out that the known methods are difficult to realize in an industrial production scale without further 5 losses in the overall yield and quality. Protecting the two carboxylic acid functions of Bimosiamose precursor substances as the corresponding methyl esters is known in prior art. However, surprisingly it turned out that the method of present invention works particularly 10 well when ethyl esters are applied as protecting groups. They have a clear advantage compared e. g. to the corresponding methyl esters. They are much more stable with respect to the conditions of an industrial scale and there is no need for the groups to be cleaved and re-installed during the synthesis process of Bimosiamose. Therefore, the number of reaction steps can be reduced as compared to the methods of the prior art [see T. Kogan et 15 al., J. Medicinal Chemistry 41(7), 1998, 1099-1111; US 5 919 768; US 5 712 387]. One task of the present invention is to provide a process that allows for the chemical synthesis of Bimosiamose also in an industrial production scale and in a high quality and purity. The quality of the product should be so high that it can be applied for the 20 manufacturing of drug products, diagnostics and/or cosmetics containing Bimosiamose. Additionally, the process or method of present invention shall make use of cost-effective starting materials, intermediates and reagents. The process of preparation shall be characterized by generating the product Bimosiamose in few process steps, in a high overall yield and with a high degree of purity. 25 The technical problem is solved by a process of preparation of 1,6-Bis-[3-(3 carboxymethylphenyl)-4-(2-a-D-mannopyranosyloxy)-phenyl] hexane, compound of formula (I) or Bimosiamose, O O H O OH O O HO,,.

It will be understood, however, that 35 the specific dose level for any particular patient, whether human or other animal, will depend upon a variety of factors including the body weight, general health, sex, diet, time WO 2011/138365 PCT/EP2011/057130 - 10 and route of administration, rates of absorption and excretion, combination with other drugs and the severity of the particular disease being treated. In one particular embodiment of the method of preparation, the compound (I) is prepared 5 starting from 2-Methoxyphenylboronic acid (2'-Methoxy-biphenyl-3-yl)-acetic acid (A) which is generated by means of a Pd catalyst and in a high purity of more than 98% (in particular more than 99%) and a yield of more than 90% (in particular more than 93%).

In one embodiment 1,6-bis-[3-(3-carboethoxymethylphenyl)-4-hydroxyphenyl]-hexane (D) 25 is reacted with an appropriately protected mannopyranosyl halide in the presence of a catalytic amount of a Lewis acid and in a temperature range between -10 0 C to +15'C to obtain 1,6-bis-[3-(3-carboethoxymethylphenyl)-4-(tetra-0-pivaloyl-a-D-mannopyranosyl oxy)-phenyl]-hexane (E) or the corresponding O-protected derivative, 30 In one embodiment 1,6-bis-[3-(3-carboethoxymethylphenyl)-4-(tetra-0-pivaloyl-a-D mannopyranosyl-oxy)-phenyl]-hexane (E) or the corresponding O-protected derivative is reacted with sodium methylate and subsequently with aqueous sodium hydroxide to 1,6 bis-[3-(3-carboxymethylphenyl)-4-(2-a-D-mannopyranosyloxy)-phenyl]-hexane, the crude product (I), 35 In one embodiment 1,6-bis-[3-(3-carboxymethylphenyl)-4-(2-a-D-mannopyranosyl-oxy) phenyl]-hexane is recrystallized from an organic solvent (such as ethanol, methanol or WO 2011/138365 PCT/EP2011/057130 - 11 tetrahydrofuran) and optionally water to obtain Bimosiamose in high quality and purity of more than 98% (in particular more than 98.5%). The introduction of the mannose units into the molecule Bimosiamose is known in prior art 5 to work well, when the aglycon of Bimosiamose is reacted with tetra-O-pivaloyl-a-D mannopyranosyl fluoride, see US 5 712 387. It surprisingly turned out, that tetra-O pivaloyl-D-mannopyranosyl fluoride as a mixture of the a/ -forms - which is much easier accessible and more cost-effective than the pure a-anomer - gives Bimosiamose in the same optical (stereochemical) purity. The recrystallization of the crude product 10 Bimosiamose from ethanol/water mixtures or isopropanol/water mixtures can lead to the so-called polymorph FORM 2, as described in WO 2008/028966, whereby the yield is 70%. Surprisingly, recrystallization of crude Bimosiamose from tetrahydrofuran/water mixtures gives the polymorph FORM 2 in a yield of 85%. 15 The polymorph FORM 2, see WO 2008/028966, is characterized in that it provides an X ray powder diffraction pattern for this crystalline form which shows the following diffraction angles (2Theta) based on cupric K1: at approximately 5.3' (strong peak), 20 at approximately 5.60 (strong peak), at approximately 17.40 (strong peak), at approximately 9.9' (medium peak), at approximately 10.30 (medium peak), at approximately 13.80 (medium peak), 25 at approximately 15.00 (medium peak), at approximately 16.30 (medium peak), at approximately 16.60 (medium peak), at approximately 18.70 (medium peak), at approximately 19.10 (medium peak), 30 at approximately 19.20 (medium peak), at approximately 19.80 (medium peak), at approximately 20.10 (medium peak), at approximately 20.40 (medium peak), at approximately 20.70 (medium peak), 35 at approximately 21.50 (medium peak), at approximately 24.30 (medium peak), WO 2011/138365 PCT/EP2011/057130 - 12 at approximately 24.80 (medium peak), at approximately 25.50 (medium peak), and at approximately 26.5' (medium peak). 5 The polymorph "FORM 2" of compound (I), see WO 2008/028966, provides an X-ray powder diffraction pattern substantially in accordance with Figure 1. The polymorph FORM 2 is further characterized in that is has a melting range of 158'C to 161'C. Alternatively, recrystallization of the crude product Bimosiamose from ethanol/water mixtures or isopropanol/water mixtures is a suitable method which leads to purified 10 Bimosiamose in the polymorph FORM 2 as well. A further advantage of the method of present invention is that the product Bimosiamose is obtained in an overall yield of at least 30 % (in particular 34 %) which is much higher than the yield obtained with a method of the prior art (about 2 to 3%). 15 In a further preferred embodiment of the present invention, the method for the preparation of 1,6-bis-[3-(3-carboxymethylphenyl)-4-(2-a-D-mannopyranosyloxy)-phenyl]-hexane (Bimosiamose) applies in the second step (step b) ) a conversion of (2'-Methoxy-biphenyl-3 yl)-acetic acid to (2'-Methoxy-biphenyl-3-yl)-acetic acid ethyl ester, in particular by 20 reaction with thionyl chloride, first in order to generate the corresponding acid chloride and then ethanol having the advantage of a quantitative yield and a purity of (2'-Methoxy biphenyl-3-yl)-acetic acid ethyl ester of more than 99.0%.

)
2 PdCl 2 in water is heated at 77'C for 2 h until practically no 3-bromophenyl-acetic acid is left. The mixture is extracted with toluene at ambient temperature to get rid of impurities. Toluene and further water are added to the 30 aqueous layer. Concentrated sulfuric acid is added under cooling until pH ~1 is reached. The bi-layered mixture is filtered and the layers are separated at ambient temperature. The aqueous layer is extracted with toluene. The combined organic layers are washed with diluted sulfuric acid in two portions, followed by washing with water. Some toluene is 35 distilled off and the mixture is cooled to 35'C. Heptane is added to the solution in not less than 1 h while the product precipitates. The suspension is cooled down to 3C. Obtained WO 2011/138365 PCT/EP2011/057130 - 18 crystals of (2'-methoxy-biphenyl-3-yl)-acetic acid (A) are isolated by solid-liquid separation, washed with heptane and used in the next step without drying. The yield of this step 1 of the process is 87 %, but can be improved to 91%, when 5 modifying the workup procedure as follows: A 32% hydrochloric acid is applied for the acidification instead of concentrated sulfuric acid and more water, having the positive effect that no potassium (bi-)sulfate precipitation occurs, the Vmax/Vmin ratio decreases and the two washing steps with diluted sulfuric acid are omitted. 10 Step 2: 1,4-Bis- [3-(3-carboethoxymethylphenyl)-4-methoxybenzoyl] -butane (B) A solution of (2'-methoxy-biphenyl-3-yl)-acetic acid (A) in ethanol is refluxed in the presence of catalytic amounts of concentrated sulfuric acid for 2 h until practically no (2' methoxy-biphenyl-3-yl)-acetic acid is left. The mixture is treated with a concentrated aqueous solution of potassium carbonate at ambient temperature until pH 7 is reached. 15 Ethanol is distilled off under vacuum and the distillation residue is diluted with dichloromethane. The solution is washed with water and the aqueous layer is extracted with dichloromethane. The combined organic layers are treated with sodium sulfate at ambient temperature to get rid of residual water. The mixture is filtered and the filtrate is evaporated to remove residual water and ethanol. The distillation residue ((2'-Methoxy 20 biphenyl-3-yl)-acetic acid ethyl ester) is diluted with dichloromethane and the absence of water and ethanol is checked. The solution is added to a suspension of aluminum chloride (as Lewis acid) in a polar solvent, preferably dichloromethane, at maximum 0 0 C in a rate that allows for keeping the 25 temperature of the resulting mixture at 0 0 C. A solution of adipoyl chloride in dichloromethane is slowly added at maximum 0' C (in not less than 1 hour). The mixture is stirred at 5'C until practically no (2'-Methoxy-biphenyl-3-yl)-acetic acid ethyl ester is left. The solution is added to an ice-water-mixture at maximum 5'C for hydrolysis. The layers are separated at ambient temperature. The aqueous layer is extracted with 30 dichloromethane. The combined organic layers are washed with water in two portions. Dichloromethane is distilled off without vacuum and the distillation residue is diluted with isopropyl acetate. Isopropyl acetate is partially distilled off and the mixture is cooled to 53'C. The solution is 35 treated with a small amount of water and seeded. After cooling to ambient temperature the mixture is stirred for at least 2 h. After further cooling to 3C and stirring for at least 1 h WO 2011/138365 PCT/EP2011/057130 - 19 the obtained crystals are isolated by solid-liquid-separation, washed with cold isopropyl acetate and dried under vacuum at ~45'C. The obtained crude 1,4-bis- [3 -(3 -carboethoxymethylphenyl)-4-methoxybenzoyl] -butane 5 (B) is diluted in isopropyl acetate and treated with charcoal at 75'C for 1-2 h. Then charcoal is filtered off and the filtrate is cooled to 53'C. The solution is treated with a small amount of water and seeded. After cooling to ambient temperature the mixture is stirred for at least 2 h. After further cooling to 3C and stirring for at least 1 h the obtained white crystals are isolated by solid-liquid-separation, washed with cold isopropyl acetate 10 and dried under vacuum at ~45'C to obtain 1,4-bis-[3-(3-carboethoxymethylphenyl)-4 methoxybenzoyl] -butane (B). The yield of this step 2 of the process is 70 %, but can be improved to 74%, when modifying the procedure as follows: (1) Amount of EtOH for the esterification step is 15 halved and catalytic amount of sulfuric acid is limited to not more than 5% w/w having the positive effect that neutralization of reaction mixture with potassium carbonate is omitted and EtOH is simply distilled off after the esterification reaction. (2) Further, remaining water is removed from the crude esterification product by azeotrop distillation with toluene thus omitting the drying procedure with sodium sulfate. (3) Aluminum chloride suspended 20 in dichloromethane and adipoyl chloride are pre-mixed in a reactor at 0 0 C and the ester is then added slowly to this mixture. Step 3: 1,6-Bis-[3-(3-carboethoxymethylphenyl)-4-methoxyphenyl]-hexane (C) A solution of 1,4-bis-[3-(3-carboethoxymethylphenyl)-4-methoxybenzoyl]-butane (B) in a 25 mixture of ethanol and ethyl acetate is hydrogenated in the presence of catalytic amounts of a Palladium catalyst (Pd/C catalyst of type "E101 O/W 5 % wnass" of Evonik Degussa GmbH, Germany) and trifluoroacetic acid at 52'C under a pressure of 8 bar for 6 hours until practically no 1,4-bis- [3 -(3 -carboethoxymethylphenyl)-4-methoxybenzoyl] -butane and partially hydrogenated intermediates are left. The reaction mixture is cooled to 30 ambient temperature and the catalyst is filtered off and washed with ethyl acetate. Solvents are distilled off under vacuum at max. 40' C. The distillation residue is diluted with toluene and the distillation is repeated under the same conditions. The distillation residue is dissolved in toluene to obtain a toluene solution of 1,6-bis-[3-(3-carboethoxymethylphenyl)-4-methoxyphenyl]-hexane (C) which can be 35 isolated but which also can be used directly (without isolation) in the following reaction step. The yield of this step 3 of the process is nearly 100 %.
WO 2011/138365 PCT/EP2011/057130 - 20 Step 4: 1,6-Bis-[3-(3-carboethoxymethylphenyl)-4-hydroxyphenyl]-hexane (D) The toluene solution of 1,6-bis-[3-(3-carboethoxymethylphenyl)-4-methoxyphenyl] hexane (C) from Step 3 above is diluted with further toluene and evaporated under vacuum at max. 500 C. The distillation residue is dissolved in dichloromethane and the absence of 5 water is checked. Boron tribromide is added in not less than 2 h at max. 00 C. The reaction mixture is stirred at 3C for 2 h until practically no 1,6-bis-[3-(3-carboethoxymethyl phenyl)-4-methoxyphenyl]-hexane and partially de-methylated intermediate is left. An amount of ethanol sufficient for the hydrolysis of the reaction mixture is added at a rate that allows for keeping the temperature of the resulting mixture at 3C. After warming to 10 15'C a larger amount of ethanol is added in not less than 1.5 h. Solvents are cautiously distilled off without vacuum. Ethanol is added and the mixture is refluxed for 2 h until practically no condensation side product is left. Solvents are distilled off without vacuum and the distillation residue is 15 dissolved in dichloromethane. The solution is added to an ice-water-mixture at max. 50 C. The layers are separated and the aqueous layer is extracted with dichloromethane. The combined organic layers are washed with water in two portions. Dichloromethane is distilled off without vacuum and the distillation residue is diluted with toluene. 20 As one option, toluene is distilled off under vacuum at max. 700 C. The distillation residue is dissolved in toluene again to obtain a toluene solution of 1,6-bis-[3-(3-carbo ethoxymethyl-phenyl)-4-hydroxyphenyl]-hexane (D) which can be isolated but also can be used directly in the following reaction step. 25 Alternatively, the following workup procedure may be applied in order to isolate 1,6-bis [3-(3-carboethoxymethyl-phenyl)-4-hydroxyphenyl]-hexane (D) in solid form: Toluene is distilled off under vacuum at max. 800 C. The distillation residue is dissolved in diisopropylether and some diisopropylether is distilled off to remove residual toluene. The mixture is cooled to 30 0 C and seeded. After cooling to ambient temperature the suspension 30 is stirred for at least 8 h. After further cooling to 50 C and stirring for at least 3 h crystals are isolated by solid liquid-separation, washed with diisopropylether and dried under vacuum at 35 0 C to obtain 1,6-bis-[3-(3-carboethoxymethyl-phenyl)-4-hydroxy-phenyl]-hexane (D) as a white solid. The yield of this step 4 of the process is nearly 100 %. 35 Step 5: 1,6-Bis-[3-(3-carboethoxymethylphenyl)-4-(tetra-O-pivaloyl-a-D-manno pyranosyloxy)-phenyl]-hexane (E) WO 2011/138365 PCT/EP2011/057130 - 21 The toluene solution of 1,6-bis-[3-(3-carboethoxymethyl-phenyl)-4-hydroxy-phenyl] hexane (D) from Step 4 above is diluted with further toluene and evaporated under vacuum at max. 800 C. The distillation residue is dissolved in dichloromethane and an a/ -mixture of tetra-O-pivaloyl-D-mannopyranosyl fluoride is added. Alternatively, the a- or 5 -stereoisomers of tetra-O-pivaloyl-D-mannopyranosyl fluoride can be used. Some dichloromethane is distilled off and the absence of water is checked. Boron trifluoride diethyletherate is added in not less than 2 h at max. 30 C. The reaction mixture is stirred at 0 0 C for 6 h until practically no 1,6-bis-[3-(3-carboethoxymethyl-phenyl)-4-hydroxy phenyl]-hexane and intermediates are left. The solution is added to an ice-water-mixture at 10 max. 100 C. The layers are separated and the aqueous layer is extracted with dichloromethane. The combined organic layers are washed with aqueous sodium carbonate solution in two portions and water. Dichloromethane is distilled off without vacuum and the distillation residue is diluted with toluene. Toluene is distilled off under vacuum at 65 0 C. The distillation residue is dissolved in methanol. Some methanol is distilled off and 15 the mixture is cooled to 45'C. The solution is seeded and stirred for at least 90 min at 45 0 C. After cooling to 22 0 C and stirring for at least 2 h the obtained crystals are isolated by solid liquid-separation, washed with methanol and dried under vacuum at ~40 0 C to obtain 1,6 20 bis-[3-(3-carboethoxymethylphenyl)-4-(tetra-O-pivaloyl-a-D-manno-pyranosyl-oxy) phenyl]-hexane (E). The yield of this step 5 of the process is 86 %. Step 6: 1,6-bis-[3-(3-carboxymethylphenyl)-4-(2-a-D-mannopyranosyloxy)-phenyl] hexane, crude Bimosiamose (I) 25 1,6-bis-[3-(3-carboethoxymethylphenyl)-4-(tetra-O-pivaloyl-a-D-manno-pyranosyloxy) phenyl]-hexane (E) is diluted with toluene and evaporated under vacuum at max. 700 C. The distillation residue is dissolved in a mixture of tetrahydrofuran and methanol. The absence of water is checked. Cell floc (as physical auxiliary based on cellulose) and methanolic sodium methylate 30 solution (30 %) are added at 23 0 C. The reaction mixture is stirred at 23 0 C 0 C for 8 h until practically no 1,6-bis-[3-(3-carbo-ethoxymethylphenyl)-4-(tetra-O-pivaloyl-a-D-manno pyranosyloxy)-phenyl]-hexane and intermediates are left. The mixture is filtered and washed with a mixture of tetrahydrofuran and methanol, followed by washing with methanol. The filter cake (mixture of 1,6-bis-[3-(3-carbomethoxymethylphenyl)-4-(tetra 35 O-pivaloyl-a-D-manno-pyranosyloxy)-phenyl]-hexane and cell floc) is suspended in water and aqueous NaOH solution (30 %) is added at 5 0 C. The reaction mixture is stirred at 5 0
C
WO 2011/138365 PCT/EP2011/057130 - 22 for 5 h until practically no 1,6-bis-[3-(3-carbomethoxymethylphenyl)-4-(tetra-O-pivaloyl a-D-manno-pyranosyloxy)-phenyl]-hexane is left. Cell floc is filtered off and washed with water. Diluted HCl is added to the filtrate at 2 0 C 5 until pH 2.5-3.0 is reached. After stirring at 2 0 C for at least 3.5 h the obtained crystals are isolated by solid-liquid-separation. The wet cake is suspended in water and warmed to 45 0 C. Ethanol is added and the mixture is cooled to 5 0 C. After stirring at 5 0 C for at least 3 h the obtained crystals are isolated by solid-liquid-separation, washed with a mixture of water and ethanol and dried under vacuum at ~45 0 C to obtain 1,6-bis-[3-(3-carboxy 10 methylphenyl)-4-(2-a-D-mannopyranosyloxy)-phenyl]-hexane (crude Bimosiamose). The yield of this step 6 of the process is 69 %. Step 7: Pure Bimosiamose Crude Bimosiamose (I) is dissolved in aqueous tetrahydrofuran at or slightly below reflux 15 temperature. The solution is filtered through a micro filter cloth and cooled to about 52 0 C. The solution is seeded with about 0.5 w/w% Bimosiamose and subsequently cooled to 0 0 C with a temperature gradient of 18 K/h. Without interruption of the cooling ramp additional tetrahydrofuran is added starting at 18 0 C over a period of 1 h. The white suspension is agitated for not less than 2 hours at the final temperature of 0 0 C. The product is isolated by 20 centrifugation. The wet cake is first washed with aqueous tetrahydrofuran followed by isopropanol. The wet product is dried in an agitated vacuum dryer. The yield of this purification step 7 of the process of preparation is 85 %. The compound (I) isolated corresponds to Bimosiamose in the crystal form of its 25 polymorph FORM 2, which is characterized by the X-ray spectrum of Figure 1. In this Figure 1, the relative intensity [RI] of the signals of the X-ray spectrum is shown as a function of the 2 Theta-value (based on cupric K (alpha 1)). Example 2 (Bimosiamose treatment on volonteers) 30 A study was designed to show the effect of Bimosiamose on ozone induced sputum neutrophilia after repeated inhalative doses of Bimosiamose. Using a double-blind, placebo controlled, two-period randomized cross-over clinical study design, the efficacy of Bimosiamose was examined after administration to 18 human volunteers (subjects). The 35 subjects were randomly assigned to each treatment, Bimosiamose or corresponding WO 2011/138365 PCT/EP2011/057130 - 23 placebo; the treatments were separated by a wash-out period of at least 10 days (at least 14 days between ozone challenges). In each period, eight doses of Bimosiamose (10 mg each) or corresponding placebo, were 5 administered over a period of 4 days. In order to provoke an inflammatory response, the subjects were exposed to an ozone challenge, that means to an airflow containing 250 ppb of ozone for three hours starting approximately 30 minutes after the end of the last dosing on day 4 of each treatment period. Ozone challenge was performed according to the method described by J6rres et al. [Am J Respir Crit Care Med. 161 (6), 2000, 1855-1861] 10 and Holz et al. [Clin Exp Allergy. 32 (5), 2002, 681-689]. Three hours after completion of the ozone challenge sputum was induced and processed and investigated according to the method described by Pin et al. [Thorax. 47, 1992, 25-29] and Holz et al. [Am J Respir Crit Care Med. 159 (3), 1999, 776-784; Thorax. 53(2), 1998, 83-86]. (The induction of sputum herein is a process where sputum is induced from the respiratory tract by an inhaled saline 15 stimulus). Sputum was analyzed for cellular composition (e.g. neutrophil count, lymphocyte count) and non-cellular mediators (e.g. interleukin-8 and MMP-9 levels). As compared to placebo treatment, treatment with Bimosiamose resulted in a remarkable reduction of sputum neutrophil counts and sputum interleukin-8 levels. However, Bimosiamose surprisingly also diminished significantly the sputum concentration of matrix 20 metalloproteinase-9 (MMP-9). Example 3 (Bimosiamose treatment for patients) Another study was designed to show the effect of Bimosiamose on Chronic Obstructive 25 Pulmonary Disease (COPD) after repeated inhalative doses of Bimosiamose. Using a double-blind, placebo controlled, two-period randomized cross-over clinical study design, safety and efficacy of Bimosiamose were examined in 77 patients with COPD (subjects). The subjects were randomly assigned to each treatment, Bimosiamose or corresponding placebo; the treatments were separated by a wash-out period of at least 14 days. 30 Bimosiamose (10 mg) or corresponding placebo, were administered twice daily for 28 days. Sputum was induced before and after each treatment period and processed and investigated according to the method described by Holz et al. [Changes in sputum composition during sputum induction in healthy and asthmatic patients. Clin Exp Allergy 1998; 28: 284-292] and Beeh et al. [Induced sputum cell profiles in lung transplant 35 recipients with or without chronic rejection: correlation with lung function. Thorax. 2001; 56: 557-60]. (The induction of sputum herein is a process where sputum is induced from the respiratory tract by an inhaled saline stimulus).
WO 2011/138365 PCT/EP2011/057130 - 24 The Sputum was analyzed for cellular composition (e.g. neutrophil count, lymphocyte count) and non-cellular mediators (e.g. interleukin-8 and MMP-9 levels). As compared to placebo treatment, treatment with Bimosiamose resulted in a reduction of 5 sputum neutrophil counts and sputum interleukin-8 levels. Bimosiamose also diminished significantly the sputum concentration of matrix metalloproteinase-9 (MMP-9). The results are shown in the Figure 3. This Fig.3 shows the reduction (percentage of treatment differences) of non-cellular IL-8, 10 MPO (myeloperoxidase), MMP-9) and of different cellular (Non-squamous, Neutrophils, Macrophages, Lymphocytes and Eosinophils) parameters in the sputum of patients treated with Bimosiamose compared to patients treated with placebo on treatment day 28. 15 20 25 30 35
