Full Text BACKGROUND OF THE INVENTION
Field of the Invention
[0001] The present invention relates to glycosides, the salts thereof and pharmaceutical
compositions containing these glycosides as active ingredients. Furthermore the invention provides a
method of preventing, treating or alleviating the symptoms of acute and chronic inflammatory disorders
of the airways of mammals • including asthma and asthma-related pathologies.
Summary of Related Art
[0002] Inflammation is a multi-step cascade process, any part of which may be the subject of
potential merapeutic intervention. Briefly, inflammation entails the infiltration of immunologically
competent cells (for example eosinophils, mast cells, activated T-lymphocytes) into the injury she where
they, together with resident cells, release bioactrve mediator substances (e.g., histamine, proteases, a host
of cytokines and chemokines), which increase the permeability of nearby blood vessels, attract and
stimulate bystander cells. The altered permeability of vessels resorts in a fluid exudate forming at the
injury she followed by a further influx of reactive leukocytes and their eventual efflux into the damaged
area. (For an overview see, Trowbridge and Emling, Inflammation: A Review of the Process
Quintessence Pub. Co, 1997). Secretion of collagen and mucus by, and proliferation of, resident cells
(smooth muscle and epithelial cells or fibroblasts stimulated by the released mediators) establish the
extension of pathological alterations (e.g„ airway obstruction) and contribute to their development.
[0003] Inflammation is associated with a variety of pulmonary conditions including e.g.,
intrinsic or extrinsic asthma bronchiale, any inflammatory lung disease, acute or chronic bronchitis,
pulmonary inflammatory reactions secondary to chronic bronchitis, chronic obstructive lung disease,
pulmonary fibrosis, as well as any pulmonary condition in which white blood cells may play a role
including, but not limited to, idiopathic pulmonary fibrosis and any other autoimmune lung disease.
Asthma is one of the most common forms of pulmonary inflammation affecting the large and small
airways of the lung. It impacts on 5% to 10% of the human population, resulting in an estimated 27
million patient visits, 6 million lost workdays, and 90.5 million days of restricted activity per year. The
morbidity and mortality rates for asthma are growing worldwide (Plaut and Zimmerman, "Allergy and

Mechanisms of Hypersensitivity" in Fundamental Immunology. 3rd Ed., Paul (ed.), Raven Press, New
York, NY, at 1399 (1993)).
[0004] Conventional anti-asthma treatments have been predicated on the strict avoidance of all
triggering allergens, which is inherently difficult to achieve, and on therapeutic regimens based on
pharmacological agents having unfortunate side effects and suboptimal pharmacokinetic properties. β2-
adrenergic agonists used to treat bronchospasm have no effect on airway inflammation or bronchial
hyperreactivity (Palmer et al, New Engl J. Med. 331:1314 (1994)). Also, regular or prolonged use of β2-
adrenergic agonists is associated with poor control of asthma, increase in airway hyperresponsiveness to
allergen, and reduced bronchoconstriction protection (Bhagat et al, Chest 108:1235 (1995)). Moreover,
chronic use of β2-adrenergic agents alone, by causing down regulation of β2-adrenergic receptors, is
suspected to worsen bronchial hyperreactivity. Theophylline (an anti-asthma methylxanthine) is
characterized by substantial variability in its absorbance and clearance. Corticosteroids, while relatively
safe in adult patients, are toxic for children, resulting in adrenal suppression and reduced bone density
and growth (Woolock et al, am. Respir. Crit Care Med. 153:1481 (1996)). Cromolyn, used to prevent
asthmatic episodes, is effective in preventing an asthmatic reaction only if given prior to an attack
(Volcheck et al, Postgrad Med 104(3):127 (1998)). Antihstaroines occasionally prevent or abort
allergic asthmatic episodes, particularly in children, but often are only partially effective because
histamines are only one of many inflammation associated mediators (Cuss, "The Pharmacology of
Antiasthma Medications", in Asthma as an Inflammatory Disease. O'Byrne, Ed., Dekker, Inc., New
York, at 199 (1990)) and O'Byme, "Airway Inflammation and Asthma", in Asthma as an Inflammatory
Disease. O'Byme, Ed., Dekker, Inc., New York, NY, 143 (1990)).
[0005] Thus, current drug modalities suffer from a number of drawbacks. In general,
conventional agents have a relatively short duration of action and may be partially or wholly ineffective
when administered after antigen challenge occurs. Moreover, because of serious adverse effects
associated with the use of agents such as β2-adrenergic agonists and corticosteroids, therapeutic margins
of safety with such agents are relatively narrow and patients using such agents must be carefully
monitored (see e.g., WO 94/06783, WO 99/06025, U.S. Patent Nos. 5,690,910 and 5,980,865). In a
recent clinical study, of inhaled corticosteroids, only transient improvement occurred in the airways
function of 5-11-year-old asthmatic children after the first year of therapy, with regression to that
observed with placebo over the next 3 years (The Childhood Asthma Management Program Research
Group, N. Engl. J. Med, 343:1054 (2000)). This regression can best be explained by remodeling changes
(characteristic feature of asthma) occurring in me airways that are refractory to corticosteroids (Davies,
Cvrr. Opin. Allergy Clin. Immunol, 1:67 (2001)).
[0006] It is known from relevant literature, that certain mixtures of polysulfated disaccharides
- having structures closely related to those of the present invention and which were synthesized by

nitrous acid treatment of such natural products as for example heparin or heparin sulfate, followed by
reduction with borohydride and subsequent sulfation of the partially purified samples (US .5,690,910; US
5,980,865 and WO 02/083700) - displayed remarkable anti-inflammatory effect in different asthma
models.

[0035] As used in this specification, the singular forms "a", "an" and "the" specifically also
encompass the plural forms of the terms to which they refer, unless the content clearly dictates otherwise.
For example, reference to "a modulator" includes mixtures of modulators.
[0036] As used in this specification, whether in a transitional phrase or in the body of the claim,
the terms "comprise(s)" and "comprising" are to be interpreted as having an open-ended meaning. That
is, the terms are to be interpreted synonymously with the phrases "having at least" or "including at leasf'.
When used in the context of a process, the term "comprising" means that the process includes at least the
recited steps, but may include additional steps. When used in the context of a compound or composition,
the term "comprising" means that the compound or composition includes at least the recited features or
components, but may also include additional features or components.
[0037] The term "about" is used herein to mean approximately, in the region of, roughly, or
around. When the term "about" is used in conjunction with a numerical range, it modifies that range by
extending the boundaries above and below the numerical values set forth. In general, the term "about" is
used herein to modify a numerical value above and below the stated value by a variance of 20%.
[0038] As used herein, unless specifically indicated otherwise, the word "or" is used in the
"inclusive" sense of "and/or" and not the "exclusive" sense of "either/or."
[0039] As used herein, the terms "treating" or "treatment" are used to indicate reducing,
alleviating, preventing, inhibiting the develpment of and/or reversing the symptoms of a condition.
Conditions to be treated by the methods and compositions of the invention include any condition

characterized by, or including, acute and chronic inflammatory disorders of the airways. Hence, the terms
"inflammatory disorder" or "inflammatory disorders of the airways" encompass any inflammatory lung
disease, including asthma, intrinsic or extrinsic asthma bronchiale, acute chronic bronchitis, allergic
rhinitis, pulmonary inflammatory and structural reactions secondary to chronic bronchitis, chronic
obstructive lung disease, pulmonary fibrosis. The invention is also useful for pulmonary condition in
which white blood cells and airway remodeling may play a role including but not limited to idiopathic
pulmonary fibrosis and any other autoimmune lung disease.
[0040] By "asthma" is meant a condition of allergic origins, the symptoms of which include
continuous or paroxysmal labored breathing accompanied by wheezing, a sense of constriction in the
chest, and often attacks of coughing or gasping. By "asthma-related pathology" is meant a condition
whose symptoms are predominantly inflammatory in nature with associated bronchospasm. Hence, both
asthma and asthma-related pathologies are characterized by symptoms that include narrowing of airways,
due in varying degrees to contraction (spasm) of smooth muscle, edema of the mucosa, including that of
the upper airways and mucus in the lumen of the bronchi and bronchioles. Non-limiting representative
examples of "asthma-related pathologies" include non-asthmatic conditions characterized by airway
hyperresponsiveness (e.g., chronic bronchitis, emphysema, cystic fibrosis and respiratory distress).
[0041] Compositions and methods taught herein are exemplified, for asthma. However, the
invention should not be construed as limited to this particular pulmonary disease. Asthma offers the
advantage of having been studied extensively and provides several accepted models to evaluate the
invention. It is known that sensitization and allergen challenge leads to airway hyperresponsiveness to
various agonists. Hence, acetylcholine, known as a spasmogenic agent, is capable of inducing larger
contractions of the muscle cells in tissues obtained from the trachea of sacrificed animals (which had
been sensitized to provoke airway hyper-responsiveness) than from control animals following allergen
challenge (see, e.g. Tokuoka et at, Br. J. Pharmacol. 134:1580 (2001); Nakata et at, Int. Immunol.
13:329 (2001); Emala and Hirshman, Monogr. Allergy 33:35 (1996)).
[0042] The most prominent characteristic of asthma is bronchospasm, or narrowing of the
airways. Asthmatic patients have prominent contraction of the smooth muscles of large and small
airways, increased mucus production, and increased inflammation (Plaut and Zimmerman, supra). The
inflammatory response in asthma is typical for tissues covered by a mucosa and is characterized by
vasodilation, plasma exudation, recruitment of inflammatory cells such as neutrophils, monocytes,
macrophages, lymphocytes, and eosinophils to the sites of inflammation, and the release of inflammatory
mediators by resident tissue cells (e.g., mast cells or airways epithelial cells) or by migrating
inflammatory cells (Hogg, 'Pathology of Asthma", in Asthma as an Inflammatory Disease. O'Byrne
(ed.), Marcel Dekker, Inc., New York, NY, at 1 (1990)). Asthma may be triggered by a variety of causes
such as allergic reactions, a secondary response to infections, industrial or occupational exposures,

ingestion of certain chemicals or drugs, exercise (Hargreave et at, J. Allergy Clin. Immunol. 83:1013
(1986)).
[0043] The compounds of formula (3) according to the invention have also been found effective
to decrease mucus production of bronchial epithelial cells and to inhibit growth factor mediated
proliferation of smooth muscle cells.
[0044] An increase in bronchial hyperreactivity (AHR), the hallmark of a more severe form of
asthma, can be induced by both airway antigenic and non-antigenic stimuli. Late phase response and
persistent hyperresponsiveness in allergen-induced asthma have been associated with the recruitment of
leukocytes, and particularly eosinophils, to inflamed lung tissue (Abraham et at, Am. Rev. Respir. Dis.
138:1565 (1988)). Eosinophils release several inflammatory mediators including 1S-HETE, leukotriene
C4, PAF, cationic proteins, eosinophil peroxidase.
[0045] The terms "antigen" and "allergen" are used interchangeably to describe those
molecules, such as dust or pollen that can induce an allergic reaction and/or induce asthmatic symptoms
in an individual suffering from asthma. Thus, an asthmatic individual "challenged" with an allergen or an
antigen is exposed to a sufficient amount of the allergen or antigen to induce an asthmatic response. The
compounds of formula (I) according to the invention have been found effective to treat AHR subsequent
to ovalbumin sensitization and antigen challenge.
[0046] The biological activity of the compounds of formula (I) of the present invention in
different animal models is demonstrated below:
Model 1
Examination of the effect of locally administered polysulfated glycosides on airways' hyperβ2-
responsiveness ex vivo
[0047] Inflammation of the airways may lead to bronchial hyper-responsiveness, which is a
characteristic feature of asthma.
[0048] Brown Norway (EN) rats were actively sensitized to ovalbumin (OA) by a subcutaneous
injection of 0.5 ml of OA/Al(OH)3 gel mixture (2 mg OA +10 g A1(OH)3/100 ml saline) on day 1 with
subsequent subcutaneous injections (10 mg OA + 10 g A1(OH)3/100 ml saline) given on days 14 and 21.
On day 28, animals received the compound described in example 4 intratracheally (0.01; 0.1 or 1.0
mg/kg dose) 2 hours before antigen challenge. Antigen challenge was performed by inhalation of
nebulised ovalbumin (1% antigen solution administered in a TSE inhalation system for 1 hour). Animals
were sacrificed 48 hours post antigen challenge wherein the tracheas were removed to an organ bath.

Dissected tracheas were allowed to equilibrate for 30 minutes before measuring tracheal spasmogenic
response curves to acetylcholine (Ach).
[0049] As shown in Table 1 ovalbumin challenge of sensitized animals in this model caused a
significant tracheal hyper-reactivity to acetylcholine, when the response to the spasmogenic agent was
determined 48 h after antigen challenge. The compound described in example 4 in a dose of 0.01 mg/kg,
brought this elevation back almost to control level.

* -log M acetylcholine (Ach), causing 50% contraction relative to control (mean ± SEM)
** Contraction at maximal Ach concentration relative to control (mean ± SEM)
Model 2.
Examination of the effect of polysulfated glycosides on the allergen stimulated mucus production of
airways epithelial cells.
[0050] In a sensitized animal antigenic challenge results in mucus production of airways
epithelial cells, which is a characteristic feature of allergic asthma.
[0051] Sensitized BN rats were treated intratracheally with varying (0.01-1.0 mg/kg) dose of
compound described in example 4, two hours before antigenic challenge, using a similar protocol

described in Model 1. Lungs were collected 48 hours after challenge and were fixed in 8% phosphate
buffered formaldehyde. Samples were then processed for histochemistry routinely. 5 µm thick sections
were stained with periodic-acid-Schiff (PAS) reagents and were counterstained with haematoxylin-
eosine. On the sections each epithelial cells of the airways were counted in the whole preparation at a
magnification of 400x. The number of PAS{+) [mucus producing] epithelial cells was expressed as the
ratio of the total number of epithelial cells.
[0052] As it is shown in Table 2, allergen challenge stimulates the mucus production of airways
epithelial cells (control vs. challenge). The compound significantly decreased the number of PAS(+),
mucus producing cells at the applied higher dose.

Model 3.
Examination of the effect of polysulfated glycosides on the extent of perivascular oedema developed in
asthmatic lung tissue.
[0053] In a sensitized animal antigen challenge, as a result of the developing inflammatory
processes, increases the permeability of the blood vessels resulting in plasma excudation around the
periphery of the vasculature.
[0054] Sensitized BN rats were treated intratracheally with varying (0.01-1.0 mg/kg) dose of
compound described in example 4, two hours before antigenic challenge, using a similar protocol
described in Model 1. Lungs were collected 48 hours after challenge and were fixed in 8% phosphate

buffered formaldehyde. Samples were then processed for histochemistry routinely. 5 µm thick sections
were stained with periodic-acid-Schiff (PAS) reagents and were counterstained with haematoxylin-
eosine. On the 5 µm sections, the area of the connective tissue around the vasculare was determined and
expresssed as a ratio of the area of the corresponding blood vessel itself.
[0055] As it is shown in Table 3, allergen challenge causes aedema around the vasculature, the
extent of which was significantly decreased even at the smallest dose of the examined compound.

Model 4.
IP-3 receptor antagonistic effect of polysulfated glycosides
[0056] Glycosides of the present invention, depending on their chemical structure, inhibit the
binding of inositol-l,4,5-trisphosphate (IP3) to its receptor in microsomal membrane preparations. As
EP3 is a messenger molecule playing distinguished role in the activation of different cells, interfering with
this function can explain the anti-asthmatic effect of these polysulfated glycosides.
[0057] The IP3 antagonist effect of the polysulfated glycosides were determined using rat
cerebellum membrane preparations according to Worley et al. (JBC 262, 12132, 1987). As is shown in
Table 4, all the compounds described in Examples 1-16 possess varying IP3 antagonist activity.


[0058] The pharmaceutical compositions of the present invention are intended for use with any
mammal that may experience the benefits of the methods of the invention. Foremost among such
mammals are humans, although the invention is not intended to be so limited, and is applicable to
veterinary uses. Thus, in accordance with the invention, "mammal" or "mammal in need" include
humans as well as non-human mammals, particularly domesticated animals including, without limitation, .
cats, dogs, and horses.

[0059] The term "therapeutically effective amount" is used to denote treatments at dosages
effective to achieve the therapeutic result sought. Furthermore, one of skill will appreciate that the
therapeutically effective amount of the compound of the invention may be lowered or increased hy fine-
tuning and/or by administering more than one compound of the invention, or by administering a
compound of the invention with another anti-asthmatic compound (e.g., corticosteroid). The invention
therefore provides a method to tailor the administration/treatment to the particular exigencies specific to a
given mammal. As illustrated in the following examples, therapeutically effective amounts may be easily
determined for example empirically by starting at relatively low amounts and by step-wise increments
with concurrent evaluation of beneficial effect. Clinical changes relevant to assess the therapeutic effect
of treatment according to the invention include reduction in the characteristic symptoms and signs of
asthma and related pathologies (e.g., dyspnea, wheezing, cough, bronchial hypersensitivity airway
remodeling) and improvement of pulmonary function tests. These are based upon patient' s symptoms and
physician's observations.
[0060] As used herein, the recitation of a numerical range for a variable is intended to convey
that the invention may be practiced with the variable equal to any of the values within that range. Thus,
for a variable which is inherently discrete, the variable can be equal to any integer value of the numerical
range, including the end-points of the range. Similarly, for a variable which is inherently continuous, the
variable can be equal to any real value of the numerical range, including the end-points of the range. As
an example, a variable which is described as having values between 0 and 2, can be 0,1 or 2 for variables
which are inherently discrete, and can be 0.0,0.1,0.01,0.001, or any other real value for variables which
are inherently continuous.
[0061] For local administration by inhalation for example, contemplated therapeutically
effective amounts are from about 0.1 µg/kg/day to about 1000 µg/kg/day when administered systemically
(e.g., orally administered). In an embodiment of the invention, when systemically administered,
therapeutically effective amounts are from about 0.5 µg/kg/day to about 200 µg/kg/day.
[0062] . Dosage forms and frequency of administration of the same, will depend on conventional
factors routinely considered by one of skill in the field to obtain therapeutically effective amounts as
discussed above in a given mammal. Hence, a practitioner will consider the condition being treated, the
particular compound of the invention being administered, route of administration, and other clinical
factors such as age, weight and condition of the mammal as well as convenience and patient compliance.
[0063] It will be appreciated by those of skill in the art that the number of administrations of the
compounds according to the invention will vary from patient to patient based on the particular medical
status of that patient at any given time.

[0064] When applicable (such as for the treatment of asthma, for example) the compound
according to this aspect of the invention, may be administered prior to, at the same time, or after the
mammal has been exposed to an antigen. In addition, the timing of the administration of the compound
of the invention with relation to the exposure to an antigen will vary from mammal to mammal
depending on the particular situation. A skilled practitioner "will optimize administration by careful
monitoring the patient while altering the timing and/or the order of administration of the compound of the
invention. Hence, it will be understood that the mammal need not suffer from a pulmonary inflammation
to benefit from the invention. The compounds of the invention may be administered prophylactically to
individuals predisposed to develop asthma and/or an asthma-related pathology. For example, an
individual allergic to pollen may be administered a compound of the invention (e.g., by oral
administration) on a daily basis and/or prior to going to a pollen-rich area (e.g., a garden). Likewise, an
individual with only a family history of asthmatic attacks may be administered the compounds of the
invention prophylactically - to prevent or inhibit possible onset of such an asthmatic attack.
[0065] Based on the above facts, the present invention also provides a method of treating acute
and chronic inflammatory disorders of the airways of mammals -including asthma and asthma-related
pathologies. This method comprises administering to a mammal in need of such treatment a
therapeutically effective amount of a compound of formula (I)
[0066] The compounds according to the invention are optimally formulated in a
pharmaceutically acceptable vehicle with any of the well-known pharmaceutically acceptable carriers,
including diluents and excipients (see Remington's Pharmaceutical Sciences. 18* Ed., Gennaro, Mack
Publishing Co., Easton, PA 1990 and Remington: The Science and Practice of Pharmacy. Lippincott,
Williams & Wilkins, 1995). While the type of pharmaceutically acceptable carrier/vehicle employed in
generating the compositions of the invention will vary depending upon the mode of administration of the
composition to a mammal, generally pharmaceutically acceptable carriers are physiologically inert and
non-toxic. Formulations of compositions according to the invention may contain more than one type of
compound of the invention, as well as any other pharmacologically active ingredient useful for the
treatment of the particular pulmonary inflammation being treated. Such compounds may include without
limitation, β-andrenoceptor antagonists: albuterol, metaproteranol, levalbuterol, pirbuterol, salmeterol,
bitolterol; glucocorticoids: beclomethasone, triamcinolone, flunisolide, budesonide, fluticasone;
ieukotriene-receptor antagonists and leukotriene-synthesis inhibitors: zafirlukast, montelukast, zileutin;
other anti-asthmatics: cromolyn, nedocromil, theophylline; anti-cholinergic agents: ipatropium,
oxitropium, tiotropium; H1 receptor antagonist anti-histamines: diphenydramine, pyrilamine,
promethazine, loratidine, chlorocyclizine, chlorophemiramine, fexofenadine and adrenocorticosteroids.
[0067] The compositions of the invention can be administered by standard routes (e.g. oral,
inhalation, rectal, nasal, topical, including buccal and sublingual, or parenteral, including subcutaneous,

intramuscular, intravenous, intradermal, transdermal, and intratracheal). In addition, polymers may be
added according to standard methodologies in the art for sustained release of a given compound.
[0068] Formulations suitable for administration by inhalation include formulations that can be
dispensed by inhalation devices known to those in the art. Such formulations may include carriers such as
powder and aerosols. The present invention encompasses liquid and powdered compositions suitable for
nebulization and intrabronchial use, or aerosol compositions administered via an aerosol unit dispensing
metered doses ("MDI'). Particularly preferred devices contemplated are described in U.S. Patent No.:
5,447,150.
[0069] The active ingredient may be formulated in an aqueous pharmaceutically acceptable
inhalant vehicle, such as, for example, isotonic saline or bacterostatic water and other types of vehicles
that are well known in the art. The solutions are administered by means of a pump or squeeze-actuated
nebulized spray dispenser, or by any other conventional means for causing or enabling the requisite
dosage amount of the liquid composition to be inhaled into the patient's lungs.
[0070] Powder compositions containing the anti-inflammatory compounds of the present
invention include, by way of illustration, pharmaceutically acceptable powdered preparations of the
active ingredient thoroughly intermixed with lactose or other inert powders acceptable for intrabronchial
administration. The powder compositions can be administered via a dispenser, including, but not limited
to, an aerosol dispenser or encased in a breakable capsule, which may be inserted by the patient into a
device that punctures the capsule and blows the powder out in a steady stream.
10071] Aerosol formulations for use in the subject method typically include propellants,
surfactants, and co-solvents and may be filled into conventional aerosol containers that are closed by a
suitable metering valve.
(0072] For oral administration, the anti-inflammatory compositions of the invention may be
presented as discrete units such as capsules, caplets, gelcaps, cachets, pills, or tablets each containing a
predetermined amount of the active ingredient as a powder or granules; as a solution or a suspension in
an aqueous liquid or a non-aqueous liquid; or as an oil-in-water liquid emulsion or a water-in-oil
emulsion and as a bolus, etc. Alternately, administration of a composition of all of the aspects of the
present invention may be effected by liquid solutions, suspensions or elixirs, powders, lozenges,
micronized particles and osmotic delivery systems.
[0073] Formulations of compositions of the present invention suitable for nasal administration,
wherein the carrier is a solid, include a coarse powder having a particle size, for example, in the range of
20 to 500 microns which is administered in the manner in which snuff is administered, i.e. by rapid
inhalation through the nasal passage from a container of the powder held close up to the nose. Suitable

formulations, wherein the carrier is a liquid, for administration, for example via a nasal spray, aerosol, or
as nasal drops, include aqueous or oily solutions of the compound of the invention. Semi-liquid
formulations, such as a nasal gel, are also suitable.
[0074] Formulations of compositions suitable for parenteral administration include aqueous and
non-aqueous sterile injection solutions "which may contain antioxidants, stabilizers, buffers, bacteriostats
and solutes which render the formulation isotonic with the blood of the intended recipient; and aqueous
and non-aqueous sterile suspensions which may include suspending agents and thickening agents.
[0075] The process for the synthesis of compounds of the general formula (IA), (IB) and (IC),
which are stereochemically defined representatives of compounds of the general formula (I) of the
present invention, is illustrated by the following examples.

Compounds of formula VIII, IX, XIV, XVIII, XIX, XX, XXI, XXIV, XXIX, XXXIII, XXXVII, XLIII,
XLV, XLVII, IL, LIII, LVII and LXI used as starting compounds in the examples, are concrete,
stereochemically defined, isomerically pure representatives of formula (D). Chemical structures thereof
are demonstrated below:

XXXI, XXXII, XXXIV, XXXV, XXXVI, XXXVIII, XLI, XLII, XLIV, XLVI, XLVII, LI, LII, LV,
LVI, LVIII, LIX and LX, which are used in the synthesis of the new starting materials of formula (13), are
concrete, stereochemically defined, isomerically pure representatives of formula (V). Chemical structures
thereof are demonstrated below:

















The donor molecules used in the glycosylation reactions are either commercially available, for example
the compound of formula (X)

or can be synthesized by known methods (see experimental part), for example compounds of formula
(XXX), (L) and (LIV).


[0076] The Rf values given in the examples were determined by thin layer chromatography
using silica gel (DC-Alufolien Kieselgel 60 F254, Merck, Darmstadt) and the following mixtures of
solvents:
(4) Ethyl acetate - hexane 1:1
(S) Ethyl acetate - hexane 1:2
(C) Ethyl acetate - hexane 2:1
(D) Ethyl acetate - hexane 3:1
(E) Ethyl acetate - methanol 1:1
(F) Ethyl acetate - methanol 3:1
(G) Ethyl acetate - methanol 5:1
[0077] The spots were detected either in UV light or by spraying the plates with a 1:1 mixture of
0.1 M KMn04 -1 M H2SO4 followed by heating to 200 °C. Column chromatography was performed on
Kieselgel 60. Optical rotations were measured at 20 °C. NMR spectra were recorded with Bruker Avance
500 MHz spectrometer using Me4Si as the internal standard. The assignments of the protons were based
on COSY, 2D and selective ID TOCSY as well as selective ID NOESY experiments. Multiplicities of
the 13C spectra were obtained from DEPT experiments. Connectivities between identified protons and
protonated carbons were observed by means of HMQC and HMBC experiments.

[0078J In the case of acylation reactions carried out in the presence of pyridine the "usual work-
up" means that if the product is not crystalline after pouring the reaction mixture into ice-water, it is
extracted with an organic solvent, the organic layer is washed with water, 1 M ice-cold aqueous sulfuric
acid solution until permanent acidity, water, 5% aqueous sodium bicarbonate solution and water, dried,
