Inflammatory disorders are one of the most important health problems in the world. Inflammation is in general a localized protective response of the body tissues to invasion of the host by foreign material or injurious stimuli. The causes of inflammation can be infectious agents such as bacteria, viruses, and parasites; or physical agents such as burns or radiation; or chemicals like toxins, drugs or industrial agents; or immunological reactions such as allergies and autoimmune responses or conditions associated with oxidative stress.

Inflammation is characterized by pain, redness, swelling, heat, and eventual loss of function of the affected area. These symptoms are the results of a complex series of interactions mainly taking place between the cells of the immune system. The response of the cells results in an interacting network of several groups of inflammatory mediators: Proteins (e.g., cytokines, enzymes [e.g., proteases, peroxydase], major basic protein, adhesion molecules [ICAM, VCAM]), lipid mediators (e.g., eicosanoids, prostaglandins, leukotrienes, platelet activating factor [PAF]), reactive oxygen species (e.g., hydroperoxides, superoxyde anion O.sub.2--, nitric oxide [NO] etc). However, many of those mediators of inflammation are also regulators of normal cellular activity. Thus, deficiencies of inflammatory reactions lead to a compromised host (i.e. infection) while uncontrolled and thus chronic inflammation leads to inflammatory diseases mediated in part by the excessive production of several of the above mentioned mediators.

Acute and chronic inflammation resulting from an excessive biosynthesis of inflammatory mediators is involved in numerous inflammatory disorders such as arthritis (e.g. osteoarthritis, rheumatoid arthritis), asthma, inflammatory bowel diseases, inflammatory diseases of the skin (e.g. contact dermatitis [particularly diaper area dermatitis], atopic dermatitis, xerosis, eczema, rosacea, seborrhea, psoriasis, neurodermitis, thermal and radiation burns such as sunburn, other types of skin inflammation, and the tissue-degenerating effects of aging) and chronic inflammatory disorders, such as atherosclerosis, heart diseases, metabolic syndrome X, cancer, Alzheimer's disease and pre-stages thereof such as mild cognitive impairment or photoageing which is associated with chronic skin inflammation.

Rheumatoid arthritis is a chronic inflammatory disease of the joints and is one of many different forms of arthritis. For example, arthritis includes rheumatoid arthritis, spondyloarthopathies, gouty arthritis, osteoarthritis, systemic lupus erythematosus and juvenile arthritis. Like asthma, rheumatoid arthritis is characterized at the molecular level by chronically unbalanced expression of cytokines, chemokines, kinins and their receptors, adhesion molecules and their respective receptors, as well as inflammatory enzymes.

Psoriasis is one of the most common skin problems, affecting 1-3% of the human population. Inflammatory bowel disease is a general term used to describe gastrointestinal tract diseases and includes disorders such as ulcerative colitis and Crohn's disease.

Beside the process of intravascular lipid deposition, inflammatory reactions of the endothelial (i.e. blood vessel) wall are considered to critically contribute to atherosclerosis i.e. atheroma formation. Atherosclerosis results from vascular injury which triggers inflammation. Activated macrophages, T-lymphocytes, and eventually smooth muscle cells are present in atherosclerotic plaques. Monocyte/macrophage and lymphocyte activation leads to the release of eicosanoids, cytokines and matrix metalloproteinases (MMPs) which are implicated in endothelial damage, as well as in the formation and eventually the rupture of atherosclerotic plaques. Finally, circulating inflammatory markers such as C-reactive protein (CRP), fibrinogen, and interleukins are increased or altered in groups at high-risk of coronary artery diseases (CAD). Several clinical trials indicate that elevated CRP concentration correlates with increased risk of coronary, and vascular events. Thus inflammation appears to play an important role in the initiation and progression of atheroma formation.

Inflammatory processes are also associated with the pathophysiology of Alzheimer's disease. There is evidence of inflammation in the brain of patients with Alzheimer's disease, as it is characterized by increased levels of cytokines and activated microglial cells. Thus, inflammation is not only involved in the classical inflammatory disorders (e.g., arthritis, asthma, bowel diseases) but is also associated with many chronic inflammatory disorders (e.g., atherosclerosis, heart diseases, metabolic syndrome X, cancer, Alzheimer disease).

Inflammatory events are also associated with the pathophysiology of different types of cancers (e.g. gastric and intestinal cancers, melanomas). Increased levels of inflammatory mediators such as prostaglandins have been found in cancers of breast, colon, lung and pancreas in humans.

Currently, two main classes of drugs, the corticosteroid and the nonsteroidal anti-inflammatory drugs (NSAIDs) are used to treat inflammatory disorders. NSAIDs and corticosteroids provide essentially symptomatic relief. Use of corticosteroids has declined due to a growing concern about the serious side effects of prolonged use.

NSAIDs are among the most widely used drugs, primarily for the treatment of pain and inflammatory disorders, in particular for the treatment of arthritis (i.e. pain relief). Epidemiological studies have suggested that patients taking NSAIDs have a lower risk of developing Alzheimer's disease than those not taking NSAIDs. A protective effect of NSAIDs suggests that the cyclooxygenases might be involved in the neurodegenerative process. Epidemiological studies showed a significant reduction in the risk of colorectal, gastric, esophageal, and breast cancers among people who take NSAIDs compared with those not taking NSAIDs. In animal models, NSAIDs significantly reduced tumor development.

However, long-term use of NSAIDs when treating chronic diseases such as arthritis, is limited by severe side-effects like serious gastrointestinal complications, renal toxicity or asthmatic reactions.

Therefore, there is a need for new anti-inflammatory agents with weak or no side effects. Patients with inflammatory diseases have a special interest in a type of treatment considered as "natural" with mild anti-inflammatory effects and without major side effects, which can be used for disease prevention and as adjuvant treatment. Furthermore, the treatment used needs to maintain the equilibrium between excessive and insufficient inflammatory reaction.

There are many known examples of such "natural" agents with shown anti-inflammatory action. However, a disadvantage of these "natural" compounds is that their biological and thus inhibitory activity is often inadequate. When two or more natural substances are applied concomitantly, their action can be additively or even synergistically enhanced. This lowers the required amount of each substance in order to effect disease development or treatment. Since lower doses of each of the natural substances individually can be used, there is less chance that deleterious levels are reached and also less chance of serious side-effects due to chronic use.

The nutritional supplement may serve as meal or snack replacement and generally provide nutrient calories. Preferably, the nutritional supplements provide carbohydrates, proteins, and fats in balanced amounts. The nutritional supplement can further comprise carbohydrate, simple, medium chain length, or polysaccharides, or a combination thereof. A simple sugar can be chosen for desirable organoleptic properties. Uncooked cornstarch is one example of a complex carbohydrate. If it is desired that it should maintain its high molecular weight structure, it should be included only in food formulations or portions thereof which are not cooked or heat processed since the heat will break down the complex carbohydrate into simple carbohydrates, wherein simple carbohydrates are mono- or disaccharides. The nutritional supplement contains, in one embodiment, combinations of sources of carbohydrate of three levels of chain length (simple, medium and complex; e.g., sucrose, maltodextrins, and uncooked cornstarch).

Sources of protein to be incorporated into the nutritional supplement of the invention can be any suitable protein utilized in nutritional formulations and can include whey protein, whey protein concentrate, whey powder, egg, soy flour, soy milk soy protein, soy protein isolate, caseinate (e.g., sodium caseinate, sodium calcium caseinate, calcium caseinate, potassium caseinate), animal and vegetable protein and hydrolysates or mixtures thereof. When choosing a protein source, the biological value of the protein should be considered first, with the highest biological values being found in caseinate, whey, lactalbumin, egg albumin and whole egg proteins. In a preferred embodiment, the protein is a combination of whey protein concentrate and calcium caseinate. These proteins have high biological value; that is, they have a high proportion of the essential amino acids. See Modern Nutrition in Health and Disease, eighth edition, Lea & Febiger, publishers, 1986, especially Volume 1, pages 30-32. The nutritional supplement can also contain other ingredients, such as one or a combination of other vitamins, minerals, antioxidants, fiber and other dietary supplements (e.g., protein, amino acids, choline, lecithin). Selection of one or several of these ingredients is a matter of formulation, design, consumer preference and end-user. The amounts of these ingredients added to the dietary supplements of this invention are readily known to the skilled artisan. Guidance to such amounts can be provided by the U.S. RDA doses for children and adults. Further vitamins and minerals that can be added include, but are not limited to, calcium phosphate or acetate, tribasic; potassium phosphate, dibasic; magnesium sulfate or oxide; salt (sodium chloride); potassium chloride or acetate; ascorbic acid; ferric orthophosphate; niacinamide; zinc sulfate or oxide; calcium pantothenate; copper gluconate; riboflavin; beta-carotene; pyridoxine hydrochloride; thiamin mononitrate; folic acid; biotin; chromium chloride or picolonate; potassium iodide; sodium selenate; sodium molybdate; phylloquinone; vitamin D3; cyanocobalamin; sodium selenite; copper sulfate; vitamin A; vitamin C; inositol; potassium iodide.

The nutritional supplement can be provided in a variety of forms, and by a variety of production methods. In a preferred embodiment, to manufacture a food bar, the liquid ingredients are cooked; the dry ingredients are added with the liquid ingredients in a mixer and mixed until the dough phase is reached; the dough is put into an extruder, and extruded; the extruded dough is cut into appropriate lengths; and the product is cooled. The bars may contain other nutrients and fillers to enhance taste, in addition to the ingredients specifically listed herein.

In one embodiment, the dietary supplement contains cocoa or chocolate.

Emulsifiers may be added for stability of the nutraceutical compositions. Examples of suitable emulsifiers include, but are not limited to, lecithin (e.g., from egg or soy), and/or mono- and di-glycerides. Other emulsifiers are readily apparent to the skilled artisan and selection of suitable emulsifier(s) will depend, in part, upon the formulation and final product. Preservatives may also be added to the nutritional supplement to extend product shelf life. Preferably, preservatives such as potassium sorbate, sodium sorbate, potassium benzoate, sodium benzoate or calcium disodium EDTA are used.

In addition to the carbohydrates described above, the nutraceutical composition can contain natural or artificial (preferably low calorie) sweeteners, e.g., saccharides, cyclamates, aspartamine, aspartame, acesulfame K, and/or sorbitol.

EP 1 582 512 A1 describes an extraction of hydroxytyrosol from olive leaves. A method for obtaining hydroxytyrosol from the vegetation water of de-pitted olives is disclosed in US 2004/0039066 A1 in paragraphs [0080]-[0091].

Commercially available hydroxytyrosol containing olive extracts which may be used according to the invention include e.g. extracts from olive fruits such as Polyphen-Oil.TM. from Life Extension, OleaSelect.TM. from Indena, Hytolive.RTM. from Genosa, Prolivols from Seppic, OLIVE LEAF or OLIVE Water Extract of Olea europea from Lalilab, Hitofulvic and Olife.TM. from Ebiser, hydrolysed olive leaf extract, such as described in EP1582512, olive leaf extract, rich in oleuropein, such as available from Furfural and HIDROX.RTM. from CreAgri.

Preferably HIDROX.RTM. from CreAgri such as HIDROXO.RTM. 2% spray dried powder, HIDROX.RTM. Gold freeze dried powder (9%) and HIDROX.RTM. 6% freeze dried powder organic olive juice extract are used.

An example of a synthetic process in which hydroxytyrosol may be prepared with a purity >90% is a process comprising the steps of hydrogenating 3,4-dihydroxymandelic acid or a 3,4-dihydroxymandelic acid C.sub.1-10-alkyl ester in a C.sub.1-10-alkanol in the presence of a precious metal hydrogenation catalyst and optional reduction of the formed (3,4-dihydroxyphenyl)-acetic acid C.sub.1-10-alkyl ester is to form 2-(3,4-dihydroxyphenyl)-ethanol (=hydroxytyrosol) a specific example of which is described below.

The hydrogenation may be carried out in the presence of a precious metal catalyst such as Pd and Rh, separately or in mixtures, in a manner known per se. In order to increase the activity and stability of the catalysts they are preferably used on carriers such as activated carbon, alumina or kieselguhr. The preferred hydrogenation catalyst in the present case is Pd/C.

The hydrogenation is carried out in the presence of a lower alkanol, i.e. a C.sub.1-10-alkanol, such as methanol, ethanol, propanol, isopropanol, butanol, preferably in methanol or ethanol, preferably in the presence of a strong acid, preferably hydrochloric acid, preferably at a temperature from ambient temperature to 100.degree. C. or higher, preferably from 40-65.degree. C., preferably at a hydrogen pressure at least higher than the vapor pressure of the solvent at the hydrogenation temperature. The pressure can be from normal, i.e. atmospheric pressure, to 100 bar or higher.

If desired, the reaction which is preferably carried out as a through process can be accomplished in two separate steps, i.e., a first step wherein an ester of 3,4-dihydroxymandelic acid is built by esterification of the acid and a second step wherein the 3,4-dihydroxymandelic acid lower alkyl ester is hydrogenated. The reduction of the (3,4-dihydroxyphenyl)-acetic acid C.sub.1-10-alkyl ester to give hydroxytyrosol can be achieved in a known manner. The preferred reduction agents are complex hydrids of aluminum and boron, such as LiAlH.sub.4 and NaBH.sub.4. The starting material, 3,4-dihydroxymandelic acid, is well-known and can be prepared in accordance with methods described in the literature, e.g., by condensation of catechol with glyoxylic acid.

It has been found that the compositions according to the invention are also suitable for the treatment, co-treatment or prevention of cartilage degradation or cartilage damage in joints and as such for treatment of the cartilage degradation component of joint disorders, for example degenerative joints disorders such as osteoarthritis; or sport injuries. Cartilage degradation is defined within the framework of the invention as a metabolic disorder of joint cartilage characterized by increased production of cartilage-degrading enzymes such as matrix metalloproteases.

Osteoarthritis is a chronic degenerative disease of the joint of non-inflammatory origin, which develops by wear and tear of the joints during aging and results in pain and diminished joint function. Symptoms of osteoarthritis include pain, stiffness and loss of mobility in one or more joints. Excessive joint loading increases the risk of osteoarthritis, hence osteoarthritis mostly affects the weight-bearing joints such as spine, knees and hips, but thumb and finger joints may also be affected. Joint disorders can also results from injury, i.e. microdamage or blunt trauma, fractures, damage to tendons, menisci or ligaments or can be the result of excessive mechanical stress or other biomechanical instability resulting from for example an injury or obesity.

Joint disorders due to cartilage degradation are leading causes of disability and dysfunction in the elderly; almost 80% of people over age 60 show some evidence of these disorders. Age, genetic factors, muscle disuse and weakness, trauma, obesity and anatomical abnormalities contribute to the development of the disorder.

Joint disorders are difficult to treat. Up till now, treatment was largely limited to addressing the symptoms mainly with non-steroidal anti-inflammatory drugs. The drugs are given to control the pain and to restrain swelling, but do not prevent or treat damage to the cartilage. The patients experiencing severe cartilage damage frequently require surgery, including joint replacement surgery. Therefore, there was a great need for agents that treat or prevent cartilage loss and damage, which need has been solved by the present invention.

The composition of the present invention may have one or more of the following properties: it maintains and/or improves joint health, it prevents joint stiffness, it promotes joint mobility, it provides supple and/or flexible joints, it lubricates the joints, it relieves arthritis pain, it lessens joint problems, it provides joint care, it treats or prevents joint degradation, it provides joint integrity, it retards or prevents the progression of joint damage, it supports joint function, it promotes joint health and function, it naturally supports joint health and mobility for active individuals, it maintains the active flexibility of joints, it promotes joint flexibility and promotes joint mobility.

Thus, further objects of the present invention are: Use of a composition according to the invention as cartilage-regenerating and maintaining agent. Use of a composition according to the invention for maintenance of joint health. Use of a composition according to the invention (for the manufacture of a composition) for the maintenance and regeneration of articular cartilage. A method for the regeneration and/or maintenance of (articular) cartilage in a mammal which comprises administering to a mammal in need of such regeneration and/or maintenance an effective amount of a composition according to the invention.

The invention will now be elucidated by way of the following examples, without however being limited thereto.

Example 1

Synergistic Effect

The anti-inflammatory effects combinations of OH-tyrosol or oleuropein and representatives of other groups of natural substances (isoflavones, catechins, phtalides, hydroxylated biphenyls) were evaluated in activated macrophages by determining the inhibition of the synthesis of nitric oxide and/or pro-inflammatory prostaglandins (PG). PGE.sub.2 plays a critical role in the inflammation process, while nitric oxide (NO) is a hallmark of inflammation in various chronic inflammatory diseases including various forms of arthritis, gastro-intestinal diseases and metabolic syndrome. The compounds used in the experiment were dissolved in DMSO in concentrated form and did not contain byproducts that interfered with the assays. Final vehicle (DMSO) concentration did not exceed 0.2% v/v in the assays.

The anti inflammatory effect of compounds was tested in cellular assays using a murine macrophage indicator cell line, RAW267.7, which was purchased from American Type Culture Collection, (ATCC) and cultured in DMEM according to the protocol provided by ATCC. Cells (.about.50,000/well) were seeded into flat-bottomed microtiter plates and cultured for one day. Cells were then starved in complete medium containing 0.25% FCS (D-025). After overnight culture, medium was removed and replaced by 100 .mu.L of D-025 containing the test compounds at twice the final concentration. Subsequently, 100 .mu.L of D-025 containing 2 .mu.g/ml LPS was added (i.e. final LPS concentration of 1 .mu.g/ml) and the cells cultured for 24 hours. Substances were usually tested in a concentration range from 0.2 to 50 .mu.M (or .mu.g/ml in the case of extracts) in two-fold dilution steps. Concentrations of nitrite which was generated from nitric oxide released by cells were determined by the Griess reaction using sodium nitrite as standard (see e.g Imai et al. Biochem Biophys Res Comm, 197, 105 [1993]). Briefly, 50 .mu.l of supernatant was mixed with Griess reagent 1 (25 .mu.L) and Griess reagent 2 (25 .mu.L), centrifuged and the optical density at 540 nm determined. PGE.sub.2 secreted into the cell culture medium was determined by EIA obtained from Cayman Chemicals (Ann Harbor, Wis., USA) and used according to the manufacturer's instructions. IC.sub.50 values were calculated using a two-parametric least-square fitting equation [y=A+((B-A)/(1+((C-x)^D))] for best-fit curves (Excel fit software program).

In Table 1 it is shown that individually, all substances inhibited the production of inflammatory mediators. This is indicated by IC.sub.50 values, which vary between substances reflecting substance-specific biological potencies.

In Table 2 it is shown that hydroxytyrosol (OH-Tyrosol) or oleuropein when combined with resveratrol, ligustilide, EGCG, honokiol, genistein or Magnolia Bark extract synergistically inhibits nitric oxide production. A positive value for .DELTA. (observed-additive) means that the two substances out-perform the inhibitory power of the two individual components of the mixture.

Synergistic Effects Observed with a Combination of Lycopene Resveratrol and OH-tyrosol

In a methodological approach that was similar to that described for Example 1, the synergistic effect of lycopene, resveratrol and OH-tyrosol was tested on the inflammatory response. Dose-dependent effects of each substance on the production of nitric oxide or PGE.sub.2 in macrophages were determined. Unlike resveratrol or OH-tyrosol, lycopene had no anti-inflammatory effect (at <8 .mu.mol/L). In the concentration range where synergistic effects were revealed, single compounds had low or no inhibitory effect on the production of inflammatory mediators. Yet, unexpectedly the combination significantly reduced NO produced by activated macrophages. Similar features were observed with regard to the effect on PGE.sub.2 production.

The data surprisingly showed that a combination of lycopene to resveratrol to OH-tyrosol at a molar ratio of about 1:6:6 exert a synergistic inhibitory effects on production of inflammatory mediators as exemplified for nitric oxide and PGE.sub.2.
