Description

WO 2005/061523 PCT/AU2004/001800 GLYCOSAMINOGLYCAN (GAG) MIMETICS TECHNICAL FIELD 5 The invention that is the subject of this application lies in the area of compounds that mimic the structure of certain carbohydrates. More particularly, the invention lies in the area of glycosaminoglycan (GAG) mimetics. Specifically, the invention relates to compounds comprising at least one charged group that are designed to mimic the structure of GAGs. The invention also relates to methods for 10 the preparation of the compounds, compositions comprising the compounds, and use of the compounds and compositions thereof for the antiangiogenic, antimetastatic, anti-inflammatory, anticoagulant, antithiombotic, and/or antimicrobial treatment of a mammalian subject. The invention further relates to the use of the compounds and compositions thereof in the treatment of a mammalian subject having a condition amenable to treatment with such agents. 15 BACKGROUND ART Glycosaminoglycans (GAGs) are linear, polyanionic polysaccharides that are produced by most animal cells and are usually found attached to a protein core [1,2]. GAGs occur abundantly (as proteoglycans) and are extruded by cells to the cell surface and into the extracellular matrix (ECM) [3]. It has been recognised that GAGs, especially those belonging 20 to the heparan sulfate (HS) family (HS-GAGs), mediate numerous physiological processes. For example, HS-GAGs play key roles in cell growth and development, angiogenesis, coagulation, tumour metastasis, cell adhesion, activation of growth factors, binding of cytokines and chemokines, and infection by bacteria and viruses [4-6]. In recent years there has been a dramatic increase in the list of proteins that interact with GAGs and the list 25 continues to grow. The emerging view is that unique sequences of extracellular GAGS bind specifically to important proteins and by doing so influence fundamental biological processes. It has been shown that molecules that mimic the structure of certain GAGs-which molecules are referred to as "GAG mimetics"-can bind to GAG-binding proteins and modulate their biological activity: e.g., the activation of AT-III by various pentasaccharides 30 [7,8], or the activation of fibroblast growth factors (FGFs) by sucrose octasulfate [9]. Similarly, it has been shown that GAG mimetics can antagonise the binding of a GAG to its target protein and in so doing inhibit that protein's biological or disease function. For example, anticancer agents that have been developed to target HS-binding angiogenic growth factors WO 2005/061523 PCT/AU2004/001800 -2 include polysulfonated compounds [10], suramin and the related suradistas [11], and sulfated oligosaccharides [12,13]. The present invention relates to novel, small molecule GAG mimetics that bind to GAG-binding proteins and modulate their functions. The compounds incorporate at least one 5 negatively charged group (preferably a sulfo group) to interact with the positively charged residues in the GAG-binding site of the target proteins, and also contain one or more substituents to form interactions with other protein residues in and around the above-mentioned binding site. Important and distinguishing features of the compounds described herein are that they have fewer sulfo groups and are of lower molecular weight than previously described 10 polysulfated GAG mimetics such as the sulfated oligosaccharides [12,13]. Another important feature is that their structures are based on cyclic scaffolds (e.g., a monosaccharide) with sulfo groups and other substituents placed in specific, pre-defimed orientations about the ring, thus differing significantly from the simple, randomly charged GAG mimetics described by Kisilevsky [14]. The binding of the compounds described herein to a selection of HS-binding, 15 angiogenic growth factors is demonstrated via a surface plasmon resonance (SPR) solution affinity assay. Additionally, a selection of compounds are shown to inhibit the HS-mediated infection of cells and cell-to-cell spread by herpes simplex virus. One aspect of the present invention is the utilisation of the Ugi reaction [15,16] to provide a diverse array of GAG mimetics. The capacity for variation in the manner in which 20 the individual charged structures are connected to one another or to other functional groups as well as the scope of application to mimic the diverse structural variation of GAGs is demonstrated. As will be apparent to those skilled in the art, the functionalisation of the cyclic scaffolds is not limited to the Ugi reaction. For example, the use of many other reactions such as alkylation, acylation and cycloaddition is demonstrated. 25 SUMMARY OF THE INVENTION It is an object of the invention to provide novel charged compounds that have utility as GAG mimetics. It is a further object of the invention to provide effective synthetic routes for the preparation of the subject compounds. 30 According to a first embodiment of the invention, there is provided a compound of the formula WO 2005/061523 PCT/AU2004/001800 -3

Preferred compounds of the invention have the general structures of formulae III-VI, as defined in Tables 1-4 below. In order that the invention may be more readily understood and put into practice, one or 10 more preferred embodiments thereof will now be described, by way of example only. DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS The following abbreviations are used herein: GAG glycosaminoglycan HS heparan sulfate 15 FGF fibroblast growth factor aFGF acidic fibroblast growth factor (or FGF-1) bFGF basic fibroblast growth factor (or FGF-2) VEGF vascular endothelial growth factor SPR surface plasmon resonance 20 HSV herpes simplex virus The present inventors have found that a broad range of compounds with GAG mimetic properties can be synthesised using a number of different strategies as illustrated below in the examples. These compounds have utility in the prevention or treatment in mammalian subjects of a disorder resulting from angiogenesis, metastasis, inflammation, microbial infections, 25 coagulation or thrombosis. This utility results from the ability of the compounds to modulate the activity of GAG-binding proteins responsible for disease processes. The GAG mimetics of the invention, as indicated above, can be synthesised using a number of different routes, including the Ugi reaction, and generally incorporating sulfonation in the process. 30 Preferred compounds according to the first embodiment of the invention as defined above include those embraced by generic structures I and II and those included in Tables 1-4 below.
WO 2005/061523 PCT/AU2004/001800 -6 As indicated above, the compounds according to the invention have utility in the prevention or treatment in mammalian subjects of a disorder resulting from angiogenesis, metastasis, inflammation, microbial infection, coagulation or thrombosis. The compounds have particular utility in the treatment of the foregoing disorders in humans. The compounds 5 are typically administered as a component of a pharmaceutical composition as described in the following paragraphs. Phannaceutical compositions for oral administration can be in tablet, capsule, powder or liquid form. A tablet can include a solid carrier such as gelatine or an adjuvant or an inert diluent. Liquid pharmaceutical compositions generally include a liquid carrier such as water, 10 petroleum, animal or vegetable oils, a mineral oil or a synthetic oil. Physiological saline solution, or glycols such as ethylene glycol, propylene glycol or polyethylene glycol may be included. Such compositions and preparations will generally contain at least 0.1 wt% of the compound. Parenteral administration includes administration by the following routes: 15 intravenously, cutaneously or subcutaneously, nasally, intramuscularly, intraocularly, transepithelially, intraperitoneally and topically. Topical administration includes dermal, ocular, rectal, nasal, as well as administration by inhalation or by aerosol means. For intravenous, cutaneous or subcutaneous injection, or injection at a site where treatment is desired, the active ingredient will be in the form of a parenterally acceptable aqueous solution 20 which is pyrogen-free and has suitable pH, isotonicity and stability. Those of skill in the art will be well able to prepare suitable solutions using, for example, solutions of the subject compounds or derivatives thereof. In addition to the at least one compound and a carrier or diluent, compositions according to the invention can further include a pharmaceutically or veterinarially acceptable 25 excipient, buffer, stabiliser, isotonicising agent, preservative or antioxidant or any other material known to those of skill in the art. It will be appreciated by the person of skill that such materials should be non-toxic and should not interfere with the efficacy of the compound(s). The precise nature of any additive may depend on the route of administration of the composition: that is, whether the composition is to be administered orally or parenterally. 30 With regard to buffers, aqueous compositions typically include such substances so as to maintain the composition at a close to physiological pH or at least within a range of about pH 5.0 to about pH 8.0.
WO 2005/061523 PCT/AU2004/001800 -7 Compositions according to the invention can also include active ingredients in addition to the at least one compound. Such ingredients will be principally chosen for their efficacy as antiangiogenic, antimetastatic, anti-inflammatory, anticoagulant, antithrombotic, antimicrobial agents but can be chosen for their efficacy against any associated condition. 5 A pharmaceutical or veterinary composition according to the invention will be administered to a subject in either a prophylactically effective or a therapeutically effective amount as necessary for the particular situation under consideration. The actual amount of at least one compound administered by way of a composition, and rate and time-course of administration, will depend on the nature and severity of the condition being treated or the 10 prophylaxis required. Prescription of treatment such as decisions on dosage and the like will be within the skill of the medical practitioner or veterinarian responsible for the care of the subject. Typically however, compositions for administration to a human subject will include between about 0.01 and 100 mg of the compound per kg of body weight and more preferably between about 0.1 and 10 mg/kg of body weight. 15 The compounds can be included in compositions as pharmaceutically or veterinarially acceptable derivatives thereof. As used herein "derivatives" of the compounds includes salts, coordination complexes with metal irons such as Mn 2 + and Zn 2 +, esters such as in vivo hydrolysable esters, free acids or bases, hydrates, or prodrugs. Compounds having acidic groups such as phosphates or sulfates can form salts with alkaline or alkaline earth metals such 20 as Na, K, Mg and Ca, and with organic amines such as triethylamine and Tris (2-hydroxyethyl) amine. Salts can also be formed between compounds with basic groups, such as amines, with inorganic acids such as hydrochloric acid, phosphoric acid or sulfuric acid, or organic acids such as acetic acid, citric acid, benzoic acid, fumaric acid, or tartaric acid. Compounds having both acidic and basic groups can form internal salts. 25 Esters can be formed between hydroxyl or carboxylic acid groups present in the compound and an appropriate carboxylic acid or alcohol reaction partner, using techniques that will be well known to those of skill in the art. Prodrug derivatives of the compounds of the invention can be transformed in vivo or in vitro into the parent compounds. Typically, at least one of the biological activities of a parent 30 compound may be suppressed in the prodrug form of the compound, and can be activated by conversion of the prodrug to the parent compound or a metabolite thereof. Examples of prodrugs are glycolipid derivatives in which one or more lipid moieties are provided as substituents on the moieties, leading to the release of the free form of the compound by WO 2005/061523 PCT/AU2004/001800 -8 cleavage with an enzyme having phospholipase activity. Prodrugs of compounds of the invention include the use of protecting groups which may be removed in vivo to release the active compound or serve to inhibit clearance of the drug. Suitable protecting groups will be known to those of skill in the art and include an acetate group. 5 As also indicated above, compounds according to the invention have utility in the manufacture of a medicament for the prevention or treatment in a mammalian subject of a disorder resulting from angiogenesis, metastasis, inflammation, coagulation, thrombosis and/or microbial infection. Processes for the manufacture of such medicaments will be known to those of skill in the art and include the processes used to manufacture the pharmaceutical 10 compositions described above. The compounds falling within the scope of the invention have been found to have bind growth factors. In particular, it has been established that the compounds have affinity for aFGF, bFGF and VEGF. The compounds thus have utility as antiangiogenic, antimetastatic and/or anti-inflammatory agents in the treatment of mammalian subjects including humans. 15 The uses of the compounds include the treatment of angiogenesis-dependent diseases such as angiogenesis associated with the growth of solid tumours, and proliferative retinopathies, as well as the treatment of inflammatory diseases and conditions such as rheumatoid arthritis. The compounds may also activate the growth factors and could thus be used in cardiovascular treatments. 20 As further indicated above, the compounds of the invention additionally have utility as anticoagulant or antithrombotic agents. The compounds can therefore be used for both the prophylaxis and treatment of many thrombotic and cardiovascular diseases, the most notable of these being deep venous thrombosis, pulmonary embolism, thrombotic stroke, peripheral arterial thrombosis, unstable angina and myocardial infarction. Since compositions of the 25 charged aminoacid compounds can be delivered orally, the compounds are an attractive alternative to warfarin, a widely used oral anticoagulant with severe side effects. The compounds of the invention additonally have been found to inhibit viral infection and thus have utility as antiviral agents in the treatment or prevention of many viral infections. The compounds of the invention are particularly suited for the treatment or prevention of 30 infection resulting from pathogens which utilise HS as an attachment/entry receptor [6], for example, HSV, HIV, Dengue virus, Yellow fever virus, Cytomegalovirus and Hepatitis C virus. Similarly, the compounds of the invention are also suited for the treatment or prevention of infection resulting from non-viral microbial pathogens which utilise HS as an WO 2005/061523 PCT/AU2004/001800 -9 attachment/entry, for example, Plasmodium (malaria). Most notable is the inhibition by the compounds of the invention of the cell-to-cell spread of HSV-1 and HSV-2. Having broadly described the invention, non-limiting examples of the compounds, their synthesis, and their biological activities, will now be given with reference to the accompanying 5 Tables which will be briefly described in the following section of this specification. General Procedures General procedure for alkylation and deprotection of diols The diol (1 eq.) in DMF was added dropwise to a cooled (00), stirred suspension of pre washed (hexane) NaH (5 eq.) in DMF. Once the addition was complete, stirring was 10 maintained (0 0 -- +r.t., 20 min). The mixture was cooled (00, 5 min) and the alkyl halide (2 eq.) was introduced dropwise with continued stirring (0*-+r.t., o/n). The mixture was cooled once again (00) and MeOH (5 mL) was introduced with continued stirring (5 min). The solvent was evaporated and the residue subjected to workup (EtOAc) and flash chromatography to homogeneity (TLC). This residue was co-evaporated (2 x 10 mL MeCN). The crude mixture 15 and p-TsOH-H 2 0 (50 mg) in MeOH/MeCN (1:1) was heated under reflux (1 h). The mixture was cooled (r.t.) and Et 3 N (100 pL) was added prior to evaporation of the solvent. The residue was subjected to flash chromatography (EtOAc/hexane) to yield the diol. General procedure for sulfonation of alcohols A mixture of the alcohol and SO 3 -trimethylamine (2 eq per hydroxyl group) in DMF 20 was heated (600, o/n). The cooled (r.t.) reaction mixture was treated with MeOH and then made basic (to pH>10) by the addition of Na 2
CO
3 (10% w/w). The mixture was filtered and the filtrate evaporated and co-evaporated (H20). Where deacylation of the sulfated product was required, the crude product was taken up in water and 1M NaOH was added (2 eq per acyl group). When deprotection was complete the product was carried through to the next stage. 25 The crude sulfated material in H20 was subjected to size exclusion chromatography. The pure fractions were evaporated and co-evaporated (H20) and then lyophilised (H 2 0) to yield the sulfated product. When required, after lyophilisation the product was passed through an ion exchange resin column (AG*-50W-X8, Na' form, 1 x4 cm, deionized H20, 15 mL) in order to transfer the product uniformly into the sodium salt form. The solution collected was 30 evaporated and lyophilised to give the final product as a colourless glass or white power. Size exclusion chromatography Size exclusion chromatography (SEC) was performed over Bio-Gel P-2 in a 5 x 100 cm column with a flow rate of 2.8 mL/min of 0.1 M NH 4
HCO
3 , collecting 2.8 min (7.8 mL) WO 2005/061523 PCT/AU2004/001800 - 10 fractions. Fractions were analysed for carbohydrate content by TLC (charring) and/or for poly charged species by the dimethyl methylene blue test, and then for purity by capillary electrophoresis (CE) and those deemed to be free of salt were pooled and lyophilised. In the cases of the presence of undersulfated by-products or other salt contaminants 5 (normally only small amounts, but often detected), an LH20 SEC step (2 x 95 cm, deionized water, 1.2 mL/min, 3.5 min per vial) was applied to remove them completely. Dimethyl methylene blue Test Dimethyl methylene blue (DMB) reagent was prepared by dissolving 16 mg of DMB in 1 L of deionized water containing 3.04 g of glycine, 2.37 g of NaCl. 0.1 M HCI (95 ml) was 10 added to adjust the pH to 3.0. The stock solution was stored in a brown coloured bottle at r.t. (the solution was stable for at least 3 months under such conditions). A 96-well microtitre plate was loaded with 10 pL of fraction solution per well. 55 tL of DMB stock solution was added into each used well. An instant colour change from blue to pink indicated the presence of polycharged species, i.e., sulfated product fractions. 15 General procedure for NIS glycosylations Glycosyl acceptor (1 eq), thioglycoside donor (1.1 eq), 500 mg of freshly activated powdered 3A molecular sieves and 10 mL of dry DCM were stirred at -20" for 20 min before 1.3 eq of NIS and 1 drop of TfOH were added. Stirring was continued at -20' until the reaction was complete by TLC (-4 h) before 400 pL of Et 3 N was added. Evaporation (in vacuo) onto 20 silica gel and flash chromatography yielded the glycosylated product. General procedure for Ugi four-component reaction Solutions of the acid (1 eq), amine (1 eq), carbonyl compound (1 eq) and isocyanide (1 eq) in MeOH, MeOH-THF (varied ratios) or CHCl 3 were transferred into a reaction vial (final concentration: 0.1-0.5 M). When D-glucuronic acid was the acid component, it was added as a 25. solid. In the case of bis-acid, bis-amine, bis-aldehyde or bis-isocyanide, the amount was 0.5 eq. The mixture was stirred or shaken at r.t. or 60 'C for 1 h to 5 days. The progress of the reaction was monitored by TLC. The mixture was evaporated and the residue was purified by flash chromatography or dried completely under high vacuum followed by direct peracetylation and purification by flash chromatography. 30 General procedure for acetylation of hydroxyl groups: The corresponding alcohol was dissolved in DCM-pyridine (15:1 v/v, 0.15 M) containing DMAP (0.42 mol%). Acetic anhydride (2 eq per hydroxyl) was added and the mixture was stirred at r.t. o/n. The mixture was poured into ice-chilled 0.5 M HCl and WO 2005/061523 PCT/AU2004/001800 - 11 extracted with CHCl 3 . The organic phase was separated and washed with cold 0.5 M HCl (x2), brine, and dried (MgSO 4 ). The solution was filtered and evaporated. The residue was purified by flash chromatography (gradient elution with hexane-EtOAc) to give pure product. General procedure for Zemnplin deacetylation/debenzoylation: 5 A solution of the acetate/benzoate in anhydrous MeOH (0.1 M) was treated with a solution of sodium methoxide in MeOH (1.35 M, 0.2-0.6 eq). The mixture was stirred at r.t. for 1-3 h (monitored by TLC). Acidic resin AG*-50W-X8 (H+ form) was added to adjust the pH to 6-7, the mixture was filtered and the resin was rinsed with MeOH. The combined filtrate and washings were evaporated in vacuo and thoroughly dried to give the poly-ol product. 10 General procedure for deprotection of benzyl ethers via hydrogenolysis To a solution of the benzyl ether-protected compound (0.03 mmol) in MeOH or EtOH (2 mL) was added 5% Pd/C or 20% Pd(OH) 2 on charcoal (30 mg or excess). The mixture was loaded in a miniclave (Bichi AG, Uster/Switzerland) and stirred under hydrogen atmosphere (50 psi) for 2-10 h. Alternatively, the mixture was bubbled with hydrogen gas for 1 h then 15 stirred at r.t. under 1 atmosphere of hydrogen for 1-5 days. The reaction was monitored by TLC (EtOAc or MeCN-water 10:1). The mixture was filtered and rinsed with MeOH, or EtOH. The filtrate was evaporated and dried under high vacuum, checked by IH NMR, freeze dried and used directly for sulfonation. Methylation of hydroxyl groups 20 The dried poly-ol was dissolved in anhydrous DMF (0.04 M) under argon and stirred with NaH (60% suspension in mineral oil, 1.2 eq per hydroxyl) at r.t. for 1 h. lodomethane (1.2 eq per hydroxyl) was added and stirring continued o/n. MeOH was added and the mixture was evaporated onto silica and purified by flash chromatography. General procedure for Huisgen cycloaddition reactions. 25 The sulfated sugar azide was dissolved in water (0.75 M) and a solution of acetylene in t-butanol (0.9 M, 1 eq) was added. To this mixture was added a solution of copper (II) sulfate (0.3 M in water, 5 mol%) and a solution of sodium ascorbate (1 M, in water, 20 mol%). The mixture was shaken on a minishaker at r.t. o/n, and purified by column chromatography (silica 1x18 cm, gradient elution with EtOAc-MeOH-H 2 0 50:2:1, 20:2:1 to 10:2:1) to give the 30 corresponding triazole product.

These additional compounds are included in the tables giving the results of biological testing of compounds according to the invention. Example 20 Biological Testing of Compounds Methods 15 1. Growth Factor Binding Binding affinities of ligands for the growth factors were measured using a surface plasmon resonance (SPR) based solution affinity assay. The principle of the assay is that heparin immobilised on a sensorchip surface distinguishes between free and bound growth factor in an equilibrated solution of the growth factor and a ligand. Upon injection of the 20 solution, the free growth factor binds to the immobilised heparin, is detected as an increase in the SPR response and its concentration thus determined. A decrease in the free growth factor concentration as a function of the ligand concentration allows for the calculation of the dissociation constant, Kd. It is important to note that ligand binding to the growth factors can only be detected when the interaction involves the heparin binding site, thus eliminating the 25 chance of evaluating non-specific binding to other sites on the protein. A 1:1 stoichiometry has been assumed for all protein:ligand interactions. The preparation of heparin-coated sensorchips, via immobilisation of biotinylated BSA heparin on a streptavidin-coated sensorchip, has been described [24]. Heparin has also been immobilised via aldehyde coupling using either adipic acid dihydrazide or 1,4-diaminobutane. 30 For each Kd measurement, solutions were prepared containing a fixed concentration of protein and varying concentrations of the ligand in buffer. Ligands binding to FGF-1 and VEGF were measured in HBS-EP buffer (10 mM HEPES, pH 7.4, 150 mM NaCl, 3.0 mM EDTA and 0.005% (v/v) polysorbate 20), while binding to FGF-2 was measured in HBS-EP buffer WO 2005/061523 PCT/AU2004/001800 -35 containing 0.3 M NaCi [24]. Prior to injection, samples were maintained at 4 'C to maximise protein stability. For each assay mixture, 50-200 ptL of solution was injected at 5-40 pL/min and the relative binding response measured. All surface binding experiments were performed at 25 'C. The surface was regenerated by injection of 40 PL of 4M NaCl at 40 pL/min, 5 followed by injection of 40 iL of buffer at 40 pL/min. Sensorgram data were analysed using the BIAevaluation software (BlAcore). Background sensorgrams were subtracted from experimental sensorgrams to produce curves of specific binding, and baselines were subsequently adjusted to zero for all curves. The relative binding response for each injection was converted to free protein concentration using the 10 equation [P]= r [P].oi r, where r is the relative binding response and r.. is the maximal binding response. Binding equilibria established in solution prior to injection were assumed to be of 1:1 stoichiometry. Therefore, for the equilibrium, P+L ' P-L where P corresponds to the growth factor protein, L is the ligand, and P-L is the protein:ligand 15 complex, the equilibrium equation is K _[P][L] dp] and the binding equation [24] can be expressed as [p3 = [p3 (Kd + [L]lotal + [r total) + (Kd_+_[ ltotai + [lil 0 ,)2 The Kd values given are the values fit, using the binding equation, to a plot of [P] versus [L] 1 ora. Where Kd values were measured in duplicate, the values represent the average of the duplicate measurements. It has been shown that GAG mimetics that bind tightly to these 20 growth factors elicit a biological response in vivo [24]. 2. Antiviral Assays. Selected compounds were tested against two types of herpes simplex virus (HSV), i.e., WO 2005/061523 PCT/AU2004/001800 -36 HSV-1 and HSV-2, in two assays for inhibition of viral infectivity and cell-to-cell spread, as described by Nyberg et al. [25]. Monolayer cultures of African green monkey kidney cells (GMK AH1) [26] cultivated in 6-well cluster plates, were used. The viral strains used were herpes simplex virus type 1 (HSV-1) KOS321 strain [27] and HSV-2 strain 333 [28]. 5 In both assays the compounds were tested at 200 pM. (i) In the assay of HSV infectivity, the compounds were mixed with the virus, incubated for 10 min at room temperature and then the mixture was added to cells, and kept on cells for lh only to allow (or not) the virus attachment to/entry into the cells. Thus this assay reflects whether or not the compound in question has the 10 ability to bind to the virus particles and block its attachment to/entry into the cells. An inhibition is manifested as a decreased number of viral plaques. (ii) The next assay, termed HSV spread, relies on the addition of compound to the cells after the virus attachment/entry steps have already occurred. This assay reflects whether the examined compound has the ability to inhibit virus transmission from 15 an infected to an uninfected cell (cell-to-cell spread) and in addition whether the compound has the ability to enter the cells and inhibit viral replication. Lack of compound activity in the assay of virus infectivity but some activity in the virus spread assay suggests that the compound acts by entering the cells and inhibition of viral replication step(s). An inhibition is manifested as a reduction in the size of 20 viral plaques. The results (see Table 5) are expressed as % of control, ie., as the number (infectivity assay) or the size (spread assay) of viral plaques developed in the presence of compound relative to the mock-treated controls (no compound). Results 25 The results of the tests as described in the preceding section are presented in Tables 1 to 5.
