Abstract

The use of low-molecular-weight protein hydrolyzates as anti-inflammatory agents for the production of sunscreens, age-sun preparations and / or scalp-soothing preparations is proposed.

Description

Field of the Invention

The invention is in the field of cosmetic and pharmaceutical Preparations and relates to the use of low molecular weight protein hydrolyzates as anti-inflammatory agents.

State of the art

Proteins and their derivatives have been used successfully for more than 50 years Care components used in cosmetic products, made from a variety of natural sources of animal or vegetable origin. But they can not only be sorted by origin, Distinguish amino acid composition or derivatization, but especially that Molecular weight plays a role in the cosmetic properties of protein products decisive role.

The object of the present patent application was to find new effects of to find already known active ingredients and use in cosmetic and / or dermopharmaceutical agents, which are characterized by a high tolerance also distinguished for sensitive skin and also a good physico-chemical Have stability.

Description of the invention

The present invention relates to the use of low molecular weight Protein hydrolyzates as anti-inflammatory agents, especially for inhibition by UV Irradiation of induced inflammatory processes. The use also results from this of low molecular weight protein hydrolyzates for the production of sunscreens and / or after-sun preparations and for the manufacture of scalp soothing agents.

Surprisingly, it has been found that low molecular weight protein hydrolyzates, especially of vegetable origin and especially low molecular weight wheat protein hydrolyzates have pronounced anti-inflammatory effects.

More and more consumers complain about sensitive, sensitive or even irritated skin. For Protein hydrolyzates therefore have another anti-inflammatory effect interesting property. This effect is usually not only beneficial and soothing to skin and hair but is able to effectively relieve irritation on the skin to fix. Low molecular weight wheat protein hydrolyzates even show one in in vitro tests better effectiveness than acetylsalicylic acid. This way, they can help the skin to get back into balance. Therefore, the use of low molecular weight offers itself Wheat peptides e.g. B. in formulations for irritated, stressed skin or after-sun formulations.

When used in hair products, the protein hydrolyzates could e.g. B. for Stabilize and relax sensitive scalp. This is also a positive influence to expect the usual symptoms of tight scalp, such as B. the far widespread itching, so that it has a calming effect on (scalp) skin and hair.

Low molecular weight protein hydrolyzates

Low molecular weight protein active ingredients in the sense of the present invention consist in essentially from oligopeptides consisting of up to 10 amino acids, predominantly up to 6 and preferably predominantly 2 to 4 amino acids are formed. You assign a medium Molecular weight of 50 to 3000 daltons, preferably 100 to 1000 daltons and particularly preferably 200 to 600 daltons.

Commercial products include Gluadin® WLM (Cognis, Düsseldorf).

Thus, low molecular weight protein hydrolyzates have such a small molecular size that these "micro protein ingredients" are even able to penetrate deep into the hair fiber and repair, strengthen and protect them from the inside.

In the amino acid composition of the low molecular weight according to the invention Protein hydrolysates are particularly noteworthy for the high content of glutamic acid and proline. Glutamic acid is generally widespread in nature and therefore too in almost all proteins Find. Wheat protein, however, has the highest content with usually more than 30% Glutamic acid. From gluten, the protein of wheat gluten, from which glutamic acid The name of this protein building block is therefore derived first. Even though if this is not an essential amino acid, glutamic acid plays a role important role in various metabolic processes. It forms u. a. also the preliminary stage for Proline. The second dominant amino acid proline is due to its extensive Structure (with pyrrole ring) also referred to as a "helix breaker" because of its frequent occurrence Formation of a superordinate secondary structure, e.g. B. α-helix or β-sheet structures, prevented. This proline position also acts as a swivel around which the remaining protein chain can move almost freely. This gives the wheat protein molecule an extremely flexible structure and is thus able to use kinetic energy, e.g. B. in the form of Heat to intercept very effectively. In this way, denaturation of the Wheat protein can be counteracted for a long time.

The amount of low molecular weight protein hydrolyzates can be based on Final formulation 0.1 to 10, preferably 0.2 to 5 and in particular 0.5 to 2% by weight Amount of active substance.

Proof of effectiveness

The anti-inflammatory effects of low molecular weight protein hydrolyzates were the same through several Studies are proven. At the first proof of effectiveness, the activity of low molecular weight protein hydrolyzates against inflammatory processes after UV-B Irradiation on skin cultures demonstrated in vitro. This was used as a reference substance selected acetylsalicylic acid in the last two studies, which the Cyclooxygenase inhibited.

The test design is based on epidermal inflammation induction using UV-B radiation (280 up to 320 nm). This is essentially due to the activation of the enzyme phospholipase A2 or PLA2, which releases arachidonic acid from the cell membrane. Then other specific enzymes, so-called cyclooxygenases, convert Arachidonic acid in prostaglandins (PG), which are excreted by the cell. The attachment certain prostaglandins such as PGE2 is then linked to specific receptors Redness and swelling like after sunburn on the skin. These are in cell cultures UV-B effects on the cell membrane with the release of a cytoplasmic enzyme, lactate dehydrogenase (LDH). Ultimately, UV-damaged cells can get through Apoptosis, the biological process by which living organisms become defective Free cells, be eliminated. Apoptotic cells become cytoplasmic DNA fragments separated from nuclear DNA by the endonuclease.

The enzymes and parameters described above can be after application of low molecular weight protein hydrolyzates (0.1 and 0.3% original product Gluadin® WLM) on the Cell cultures are quantified and in this way allow conclusions to be drawn excellent anti-inflammatory effects in this test system too.

method

The effect of UVB radiation was investigated in vitro on keratinocytes the release of the cytoplasmic enzyme LDH (lactate dehydrogenase) was determined. This Enzyme serves as a marker for cell damage.

A defined medium containing fetal calf serum was used to carry out the tests. inoculated with the keratinocytes and low molecular weight wheat protein hydrolyzate for 72 hours added after inoculation.

The keratinocytes were then irradiated with a UVB dose (50 mJ / cm ² - tubes: DUKE GL40E).

After a further 1 day incubation at 37 ° C and 5% CO ₂ , the LDH and PGE2 content in the supernatant was determined. The content of LDH- (lactate dehydrogenase) was determined by means of an enzyme reaction (kit used to investigate the LDH content from Roche). The content of PGE2 was determined using an ELISA test (ELISA kit from Roche). To determine the DNA content in the cytoplasm of the keratinocytes, bromodeoxyuridine (BrDU) was added to the growth medium. After the trypsin treatment, the cells were centrifuged and counted. The BrdU content in DNA fragments from the cytoplasm was then determined using the ELISA test. The number of adherent keratinocytes is determined (after trypsin treatment) with a particle counter. Table 1 Evidence of anti-inflammatory activity [% versus control]

About 57% of the keratinocytes present were destroyed by UV-B radiation. The use of low molecular weight protein hydrolyzates made it toxic However, the effect can be reduced by more than 50%.

The content of released lactate dehydrogenase, however, was determined by UV-B radiation greatly increased. Here too our low molecular weight wheat peptides led to one Decrease in this characteristic UV-B effect by more than 50%.

UV-B radiation also caused a sharp increase in the released content Prostaglandins (here PGE2), even in cell culture, using Aspirin® as the reference substance was treated (Control; 0.002% AS). Through the use of low molecular weight Protein hydrolyzates, however, could be reduced by about 66% Release of PGE2 can be achieved.

The content of DNA fragments in the cytoplasm of the keratinocytes increased to a similar extent due to UV-B radiation. In contrast to the Aspirin® (Control; 0.002%) could with low molecular weight protein hydrolyzates, however, significantly reduce this Fragments can be achieved by approximately 46%.

Based on these studies it has been demonstrated that low molecular weight protein hydrolyzates use it are clearly able to provide effective protection against the consequences of UV-B radiation Build keratinocytes in cell cultures. With that, the low molecular weight showed Protein hydrolyzates have such a good anti-inflammatory effect that they are in these Investigations was even better than acetylsalicylic acid.

Another proof of effectiveness that demonstrates the positive effects of low molecular weight Protein hydrolyzate has been shown to affect inflammatory processes, its influence on the inhibition of "respiratory burst" in cell cultures in vitro.

During the epidermal inflammatory process, leukocytes are attracted such as B. PMN (polymorphonuclear neutrophil granulocytes) and by cytokines and others Messenger substances such as leukotrienes stimulated by activated or necrotic epidermal cells to be released. These activated PMNs not only release pro-inflammatory cytokines, Leukotrienes and proteases free, but also ROS (reactive oxygen species) such as Superoxide and hypochlorite anions to kill pathogenic bacteria or fungi. The PMN activity during inflammation is known as "respiratory burst" and can Mediate tissue damage from the release of ROS and lysosomal enzymes.

For this reason, the anti-inflammatory activity of low-molecular-weight protein hydrolysates "was checked to see whether it can reduce the" respiratory burst "of PMN, which is triggered by a yeast extract (" Zymosan "). For this purpose, the content of released active oxygen compounds in cell cultures (ROS) without and with zymosan and the number of cells present quantified [GM Pieper, GJ Gross: EMD 52692 (bimakalim), a new potassium channel opener, attenuates luminol-enhanced chemimuminescence and superoxide anion radical formation by zymosanactivated polymorphonuclear leucocytes. Immuno -pharmacology, 23, 191-197 (1992)], in the same way the influence of 0.03%, 0.1% and 0.3% of low molecular weight protein hydrolyzates on these parameters.Table 2 Evidence of anti-inflammatory activity - Zymosan test [% versus control]

The results clearly show the inducing influence of the yeast extract on the "respiratory burst" of the granulocytes (measured in RLU - relative luminiscence units): by the Addition of the zymosan increases the content of active oxygen compounds (ROS) by approximately ten times. However, this increase can be achieved by using low molecular weight protein hydrolyzates can be significantly reduced in one Use concentration of 0.3% even about 75%. Accordingly, small molecules are distinguished Protein hydrolyzates by an effective inhibition of the "respiratory burst" on granulocytes from constant cell number and consequently an excellent anti-inflammatory effect.

This verification approach confirms the results of the first series of tests and provides so that the anti-inflammatory effects of low molecular weight protein hydrolyzates Proven in vitro.
