Technical field of the invention

The present invention relates to a composition, obtained from a fermented plant material, having anti-inflammatory activity and capable of suppressing interleukin- 12, interleukin- 1b, and/or interleukin-6 activity; and/or suppressing of tumor necrosis factor alpha (TNF- alpha or TNF-a) activity; and/or upregulating interleukin- 10, interleukin- IRa, interleukin-4, interleukin- 11, interleukin- 13; or transforming growth factor beta (TGF-b) ; by

administration of the composition to a mammal, which composition may be used in the preparation of an anti-inflammatory substance for the treatment, alleviation or prophylaxis of a variety of disorders, including the treatment of pathological conditions associated with inflammation.

Background of the invention

Herba I medicines have always been used to fight diseases and infections in humans and animals, and plants has shown to comprise many constituents having positive nutritional and pharmacological effects in the human and animal organism. Despite the long-term knowledge and search for providing products and isolated active ingredients from plants, researchers seldom succeed because of the complexity and interplay between the individual components of the plants. Examples of potent extracts from plants that are well integrated in modern medical treatment can be found in drugs such as Morphine for treatment of severe pain, Digitalis for treatment of heart disease, Taxole for cancer treatment.

Furthermore, reaction products from plants that have been chemically or microbial treated have shown to be very interesting . Flowever, predicting the interesting reaction products and how to provide the relevant reaction product is very difficult or even impossible.

Often it is also difficult to predict that one reaction product may be responsible for the activity of e.g . a fermented plant material, as the fermented plant material is a complex mixture of an enormous number of different compounds where some products have pharmacological activity by itself and other only possess the pharmacological activity when in the complex mixture. Mammals, like humans and animals, subjected to an inflammation express an increased activity in one or more cytokines. Two of the most common cytokins that are followed when dealing with an inflammation may be selected from the group consisting of interleukin- 12, interleukin- ΐb, interleukin-6, tumor necrosis factor alpha (TNF-alpha or TNF-o), interleukin- 10, interleukin- lRa, interleukin-4, interleukin- 11, interleukin- 13; and transforming growth factor beta (TGF-b) . In particular, interleukin 10, interleukin- 12 and tumor necrosis factor alpha (TNF-alpha or TNF-a) may be followed .

Cytokines are small, secreted polypeptides from higher eukaryotes which are responsible for intercellular signal transduction and which affect the growth, division and functions of other cells. They are potent, pleiotropic polypeptides that, e.g. via corresponding receptors, act as local or systemic intercellular regulatory factors, and therefore play crucial roles in many biologic processes, such as immunity, inflammation, and

hematopoiesis. Cytokines are produced by diverse cell types including fibroblasts, endothelial cells, epithelial cells, macrophages/monocytes, and lymphocytes.

Current anti-inflammatory drugs are designed to act in an indirect manner, by blocking the action of e.g. interleukin- 12, interleukin- ΐb, and/or interleukin-6 activity; and/or suppression of tumor necrosis factor alpha (TNF-alpha or TNF-a) activityby binding to it and hereby prevents it from signaling the receptors for TNF-a on the surface of cells. This type of blocking has some serious side effects, of which some is infections such as tuberculosis, sepsis and fungal infections and possible increased cancer incidence, and an increased cytokine activity is still provided.

Flence, there is a need in the industry for new products and compounds for the efficient treatment, alleviation and/or prophylaxis of an inflammatory disease or disorder in a mammal.

Summary of the invention

Detailed description of the invention

Anti-inflammatory substances may in general have two ways of acting. Either it may be designed to act in an indirect manner, by blocking the action of e.g. interleukin-12 (IL-12) and/or TNF-alpha by binding to it and hereby prevents it from signaling the receptors for TNF-alpha or the IL-12 on the surface of cells; or the anti-inflammatory substances may act in a direct manner suppressing the activity and/or the expression of IL- 12 and/or TNF- alpha

In the present context, the terms "suppressor" or "suppressing" relates to the broad definition, and is to be given its ordinary and customary meaning to a person of ordinary skill in the art (and is not to be limited to a special or customized meaning), and refers without limitation to a molecule (e.g., natural or synthetic compound) that can decrease at least one activity of TNF-alpha or IL-12. In other words, in the present context the term "suppressor" to the change in the activity of TNF-alpha or IL-12, if there is a statistically significant change in the amount of TNF-alpha or IL-12 measured, in TNF-alpha or IL-12 activity, or in TNF-alpha or IL- 12 detected extracellularly and/or intracellular in an assay performed with a suppressor, compared to the assay performed without the suppressor.

In general, TNF-alpha suppressors reduce the physiological function of TNF-alpha or IL- 12, for example by reducing secretion of TNF-alpha or IL- 12, and thus are useful in the treatment of diseases where TNF-alpha or IL- 12 may be pathogenic, directly or indirectly.

Chromatography was performed on a Dionex UltiMate® 3000 Quaternary Rapid Separation UHPLC+ focused system (Thermo Fisher Scientific, Germering, Germany). Separation was achieved on a Kinetex 1.7u XB-C18 column (100 x 2.1 mm, 1.7 pm, 100 A, Phenomenex, Torrance, CA, USA). Formic acid (0.05%) in water and acetonitrile (supplied with 0.05% formic acid) were employed as mobile phases A and B, respectively.

Gradient conditions were as follows: 0.0-0.5 min, 2% B; 0.5-14.0 min 2-20% B; 14.0-20.0 min 20-45% B, 20.0-24.5 min 45-100% B, 24.5-26.5 min 100%, 26.5-26.55 min 100-2% B and 26.55-30.0 min 2% B. The mobile phase flow rate was 300 pi min-1. The column temperature was maintained at 25°C. Four wavelengths (205 nm, 220 nm, 250 nm and 390 nm) were monitored by a UV-VIS detector. The liquid chromatography was coupled to a Compact micrOTOF-Q mass spectrometer (Bruker, Bremen, Germany) equipped with an electrospray ion source (ESI) operated in positive or negative ionization mode. The ion spray voltage was maintained at -3900 V in negative mode. Dry temperature was set to 250°C and dry gas flow was set to 8 L min-1. Nebulizing gas was set to 2.5 bar and collision energy to 15 eV. Nitrogen was used as dry gas, nebulizing gas and collision gas.

The m/z range was set to 50-1400. AutoMSMS mode was used to obtain MS and MS/MS spectra of the three most abundant ions present at each time point with smart exclusion to also include less abundant ions. All files were calibrated based on compound spectra collected from Na + -formiate clusters at the beginning of each run.

Results

Figure 1 demonstrates a LC-QToF chromatogram illustrating a metabolite profiling of the fermented plant material and illustrates two significant peak one being most significant.

Analyzing the LC-QToF chromatogram illustrates that the fermented combination product (rape and seaweed) shows a dominating peak (peak (a) in figure 1) that has a "mass to charge ratio" (m/z) of (in negative mode) :

MSI mass = 311.2228

Retention time: 22.52 min (under the set conditions)

It is estimated that this compound is a fatty acid, in particular a modified fatty acid.

A second dominating peak (peak (b) in figure 1) was found having a "mass to charge ratio" (m/z) of (in negative mode) :

MSI mass =225.0772

Retention time: 11.86 min (under the set conditions)

From comparative studies with pure samples of FIDMPPA this second dominating peak showed to be FIDMPPA, 3-(4'-hydroxyl-3',5'-dimethoxyphenyl)propionic acid (a kimchi compound) .

Example 2

Preparation of complex plant material extract

The fermented plant material comprising the combination of rape species (rape seed) and seaweed ( Laminaria spp . ) were extracted by mixing 100 mg plant material with 1ml 80% methanol, followed by centrifugation and filtering of the supernatant (0.22pM). Next, extracts were evaporated in a centrifugal evaporator and pellets were re-solubilized in DMSO to a concentration of 100 mg/ml. These DMSO stocks were diluted and used in cell assays. Preparation of a non-polar fraction

The non-polar fraction is provided from a fermented plant material comprising the combination of rape species (rape seed) and seaweed ( Laminaria spp. ).

An 80% methanol extract of the fermented plant material was diluted 3x with water to get a 26.7% methanol extract. This extract was passed over an activated (with 100% methanol) and equilibrated (26.7% methanol) Strata C18 SPE 500 mg column, after which increasing concentrations of methanol was passed over the column to elute compounds with different polarities. The fraction collected after eluting with 90% methanol was evaporated and re-solubilized in DMSO to a concentration of 100 mg/ml. This fraction constitutes the non-polar fraction according to the present invention and used in subsequent cell assays.

Preparation of further comparative samples

Crambene (CAS No. 6071-81-4, breakdown product of the main glucosinolate in rapeseed : progoitrin), sinapic acid (CAS No. 530-59-6, main free phenolic acid in rapeseed), dihydrosinapic acid (CAS No. 14897-78-0, the "kimchi compound", very similar to sinapic acid, produced in large amounts during fermentation of rapeseed meal) and "unk comp" (CAS No. 19895-95-5, Kaempferol 3-0-p-D-sophoroside, enriched during fermentation of rapeseed meal) were all commercially available and were included in cell assys as pure compounds solubilized in water (crambene) or DMSO (sinapic acid and dihydrosinapic acid). The comparative samples were used in subsequent cell assays.

Protocol for stimulation of bone marrow-derived dendritic cells with above

extracts/samples

Bone marrow from C57BL/6 mice (Tactonic, Lille Skensved, Denmark) was flushed out from the femur and tibia and washed. 3 x 10 ⁵ bone marrow cells were seeded into 10 cm Petri dishes in 10 ml RPMI 1640 (Sigma- Aldrich, St. Louis, MO, USA) containing 10% (v/v) heat inactivated fetal calf serum supplemented with penicillin (100 U ml-1), streptomycin (100 mg ml-1), glutamine (4 mM), 50 mm 2-mercaptoethanol (all from Cambrex Bio Whittaker) and 15 ng ml-1 murine GM-CSF (harvested from a GM-CSF transfected Ag8.653 myeloma cell line). The cells were incubated for 8 days at 37°C in 5% CO2 humidified atmosphere. On day 3, 10 ml of complete medium containing 15 ng ml-1 GM-CSF was added. On day 6, 10 ml were removed and replaced by fresh medium. Non-adherent, immature DC were harvested on day 8. Afterwards, immature DCs (2 x 10 ⁶ cells ml-1) were resuspended in fresh medium, and 500 pi well-1 were seeded in 48-well tissue culture plates (Nunc, Roskilde, Denmark).

The day of the stimulation, the extracts/samples have been added to BMDCs with a volume of 100 mI for each well of the 48-well plates, and to a final concentration of 100 pg/ml, and the cells have been incubated for 1 h at 37°C with 5% CO2. Two controls have been included : one just with RPMI media, and one with the corresponding amount of DMSO present in 100 pg/ml of the extracts (in any case not exceeding the 0.1 % v/v). After 1 h of incubation with cells and extracts/samples, two different kind of stimulus have been added to cells: 1 pg/ml of LPS from Escherichia coli 0127: B8 (Sigma-Aldrich), or L. acidophilus NCFM at a multiplicity of infection (MOI) of 1. Controls of LPS and NCFM alone and together with DMSO have been included. The cells have been then incubated for 20 h. After that the supernatant of each condition and combination, tested in triplicates, has been collected and stored at -80°C until the day of the ELISA assay. The protein production of IL-12 and TNF-a was analysed using commercially available ELISA kits (Biotechne, UK).

Results

The results of the subsequent cell assays show a significant anti-inflammatory effect of the fermented plant material where inflammation was induced by NCFM MOI (see figure 1 and 2) or by LPS (see figure 3 and 4).

Figure 2 shows the effect of the non-polar fraction obtained from the fermented plant material comprising the combination of rape species (rape seed) and seaweed ( Laminaria spp . ) on inflammation induced by NCFM MOI. The figure shows that the non-polar fraction according to the present invention has a strong suppression on IL-12 activity and expression (being suppressed to less than 10% of the IL-12 activity found in the other comparative samples), see column (m) and column (n), comprising the non-polar fraction relative to in particular column (d), which is the control showing the effect of the untreated infected sample, column (d). Column (m) and column (n) also demonstrates that a dose response effect in the suppression of IL-12 is to be found with the non-polar fraction according to the present invention. Column (m) has twice the amount of non-polar fraction than the amount found in the test illustrated in column (n) and the effect of the higher amount of non-polar fraction is about 5 times higher.

Figure 3 shows the effect of the non-polar fraction according to the present invention on inflammation induced by NCFM MOI. The figure shows that the non-polar fraction according to the present invention has a strong suppression on the TNF-alpha activity and expression see column (rm) relative to column (d) which is the control showing the effect of the untreated infected sample, column (d).

The figure shows that the non-polar fraction according to the present invention has a strong suppression on the IL-12 activity and expression see column (h) relative to column (c) which is the control showing the effect of the untreated infected sample, column (c). Figure 5 shows the effect of the non-polar fraction according to the present invention on inflammation induced by LPS (Lipopolysaccharides). The figure shows that the non-polar fraction according to the present invention has a strong suppression on the TNF-alpha activity and expression see column (h) relative to column (c) which is the control showing the effect of the untreated infected sample, column (c).
