Definitions
- the invention relates to oligoribonucleotides that induce the breakdown of mRNA from enzymes that break down connective tissue and that are particularly suitable for the treatment and prophylaxis of degenerative skin symptoms, such as those associated with skin aging.
- the chronological aging of the skin is caused by endogenous, genetically determined factors and is expressed in the form of aging-related structural damage and functional disorders in the epidermis and dermis of the skin, such as dryness, roughness and the formation of dry lines / wrinkles, itching and reduced lipid replenishment by the sebaceous glands (e.g. after washing). These symptoms are summarized under the term "senile xerosis".
- the endogenous aging processes can be accelerated and intensified by exogenous factors such as UV light and chemical noxae.
- exogenous influences can cause further structural damage and functional disorders in the epidermis and dermis of the skin, such as visible vasodilation (telangiectasias, cuperosis), flaccidity and the formation of wrinkles, local hyper-, hypo- and malpigmentation (e.g. Age spots) and increased susceptibility to mechanical stress (e.g. cracking).
- degenerative skin symptoms The structural damage and functional disorders caused by exogenous and endogenous factors are referred to here as degenerative skin symptoms.
- lipid-replenishing components for example retinoids (vitamin A acid and / or its derivatives) or vitamin A and / or its derivatives.
- retinoids vitamin A acid and / or its derivatives
- vitamin A and / or its derivatives vitamin A and / or its derivatives.
- Tsukahara, K., Y. Takema, et al. describe, for example, the use of retinoic acid to reduce the formation of wrinkles. This is intended to cause regeneration of the elastic fibers (Tsukahara, K., Y. Takema, et al. (2001). “Selective inhibition of skin fibroblast elastase elicits a concentration-dependent prevention of ultraviolet B-induced wrinkle formation. "J Invest Dermatol 117 (3): 671-7).
- Active ingredients such as retinol can trigger complex metabolic processes in the cell, whereby vitamin A is generally regarded as an initiator for cell renewal.
- the substance dissolves dead horn cells, fills wrinkles from the inside and improves the skin structure.
- MMPs metalloproteinases
- dsRNA double-stranded RNA fragments
- RNAi RNA interference
- WO01 / 29058 discloses the identification of genes which are involved in RNAi and their use for modulating RNAi activity.
- RNAs short RNAs, siRNAs. Double-stranded RNA fragments with a length of 21 nucleotides were used.
- the reduction in gene expression in cells by dsRNA is known from WO01 / 68836.
- the dsRNA contains a nucleotide sequence which, under the physiological conditions of the cell, hybridizes with the nucleotide sequence of at least part of the gene to be inhibited.
- the dsRNA is preferably 400 to 800 nucleotides in length.
- WO01 / 75164 discloses the use of dsRNA with a length of 21 to 23 nucleotides for the specific inactivation of gene functions in mammalian cells by RNAi.
- Brummelkamp et al. Science 296 (2002) 550-553, describe a vector system which is to trigger the synthesis of siRNAs in mammalian cells and thus to inhibit the gene expression of a target gene.
- EP 1 214 945 A2 discloses the use of dsRNA with a length of 15 to 49 base pairs for inhibiting the expression of a given target gene in mammalian cells.
- the dsRNA can be modified to increase its stability and is said to allow the treatment of cancer, viral diseases and Alzheimer's disease.
- WO02 / 053773 relates to an in vitro method for determining skin stress and skin aging in humans and animals, suitable test kits and biochips for carrying out the method, and a test method for demonstrating the effectiveness of cosmetic or pharmaceutical active substances against skin stress and skin aging.
- Oligoribonucleotides which are suitable for the treatment of degenerative skin symptoms, have not previously been described.
- the object of the present invention is to provide compositions which enable effective treatment of degenerative skin conditions and in particular aging-related skin conditions without showing the disadvantages of the prior art.
- oligoribonucleotides which are able to inhibit the expression of the genes of connective tissue-degrading enzymes.
- Enzymes that break down connective tissue are primarily understood to mean peptidases, in particular endopeptidases, such as collagen and elastin-degrading endopeptidases, and glycosaminoglycan-degrading enzymes, in particular hyaluronic acid-degrading endo-N-acetylglucosaminidases, preferably hyaluronidases.
- endopeptidases such as collagen and elastin-degrading endopeptidases
- glycosaminoglycan-degrading enzymes in particular hyaluronic acid-degrading endo-N-acetylglucosaminidases, preferably hyaluronidases.

- the preferred endo-N-acetylglucosaminidases include:
- HYAL2 U09577
- NCBI database National Center for Biotechnology Information
- Collagen-degrading endopeptidases are enzymes that degrade the structural proteins of the connective tissue and are responsible for the degradation of elastin and collagen fibers, but also of proteoglycans. The controlled activity of these enzymes plays a critical role in tissue restructuring during development, tissue repair, and angiogenesis processes.
- Oligoribonucleotides which can inhibit the expression of zinc-dependent endopeptidases are very particularly preferred, in particular matrix metaloproteinases 1, 8 and 13, very particularly preferably matrix metaloproteinase 1.
- matrix metaloproteinases 1, 8 and 13 are very particularly preferred, in particular matrix metaloproteinases 1, 8 and 13, very particularly preferably matrix metaloproteinase 1.
- These enzymes are described, for example, in Fisher GJ, Choi HC, Bata -Csorgo Z, Shao Y, Datta S, Wang ZQ, Kang S, Voorhees JJ. , Ultraviolet irradiation increases matrix metalloproteinase-8 protein in human skin in vivo, J Invest Dermatol. 2001 Aug; 117 (2): 219-26.
- oligoribonucleotides which can inhibit the expression of the mRNA of matrix metalloproteinase 9. It is believed that this, together with metalloproteinases 1, 8 and 13, is involved in the process of so-called "photoaging" of the skin caused by UV radiation.

- Molecular bases for human leucocyte elastase inhibition. Monaldi Arch Chest Dis 49 (2): 144-9).
- Neutrophil elastase in particular is of great importance in the formation of solar elastose (Starcher, B. and M. Conrad (1995). "A role for neutrophil elastase in solar elastosis.” Ciba Found Symp 192: 338-46; discussion 346-7) Biochemical studies have shown that human dermal fibroblasts from skin with dermal elastosis have high levels of elastase and cathepsin G (Fimiani, M., C. Mazzatenta, et al. (1995). "Mid-dermal elastolysis: an ultrastructural and biochemical study.” Arch Dermatol Res 287 (2): 152-7) ,

- RNA molecules which completely or partially suppress the expression of these enzymes (gene deactivation, gene sequencing), which is presumably due to the breakdown of the mRNA from one of the above-mentioned enzymes.
- This process is called RNA interference (RNAi).
- RNAi RNA interference
- the invention thus relates to oligoribonucleotides which can induce the breakdown of the mRNA of enzymes which break down connective tissue.
- the mRNA whose degradation is to be brought about is also referred to below as the target mRNA. Accordingly, we understand target gene as the gene and in particular the coding region of the gene, the expression of which is wholly or partly suppressed.
- target sequence refers to both the target gene and the target mRNA.
- the degradation of mRNA from connective tissue-degrading enzymes by RNAi is sequence-specific, i.e. an oligoribonucleotide usually only inhibits the expression of the corresponding target gene.
- the coding regions (cDNA) of the respective genes are preferred, including the 5 ⁇ and 3 ⁇ -UTR regions.
- the regions of the coding regions which are 50 to 100 nucleotides downstream of the start codon are particularly preferred.
- oligoribonucleotides according to the invention are preferably double-stranded RNA molecules (dsRNAs) which are homologous to the sequence of the target gene, or a section thereof are, ie match the target gene with respect to sense and antisense strand.
- dsRNAs double-stranded RNA molecules
- the oligoribonucleotides according to the invention preferably have a maximum of 0 to 2, particularly preferably 0 to 1 and very particularly preferably no deviations from the target sequence, i.e. a maximum of 0 to 2 and in particular a maximum of 0 to 1 base pairs are exchanged for other base pairs.
- the oligoribonucleotides according to the invention preferably have a length of 15 to 49 nucleotides, preferably 17 to 30, particularly preferably 19 to 25 and very particularly preferably 20 to 23 nucleotides.
- the invention also relates to longer nucleotide fragments, such as e.g. dsRNAs that correspond in length to the respective target mRNAs or cDNAs. These can e.g. can be converted into fragments of 21 to 23 nucleotides in length by soluble Drosophila embryo extract (cf. WO01 / 75164). Long-chain dsRNA is also broken down into short pieces intracellularly. However, the direct use of long-chain dsRNA is generally not preferred, since this can cause non-specific inhibition of translation in mammalian cells.
- RNA duplexes according to the invention can have smooth (blunt ends) or projecting (sticky ends) ends.
- double-stranded oligoribonucleotides which have proven to ⁇ at the 3 -end comprise an overhang of 1 to 6, preferably 1 or 2 nucleotides of each strand.
- the protruding nucleotides are preferably 2 'deoxynucleotides, particularly preferably 2 ⁇ deoxythymidine residues. By using the 2 ⁇ deoxynucleotides, the costs of RNA synthesis can be reduced and the resistance of the RNA to the nuclease degradation can be increased.
- the protruding nucleotides need not necessarily be the nucleotides homologous to the target sequence and are therefore not taken into account in the deviations from the target sequence defined above.
- Oligoribonucleotides which are homologous to such a section of the target gene and in particular the corresponding double-stranded cDNA, the sense strand of which on the ⁇ '-side by two adenosine residues have proven to be particularly effective
- Thymidine and a cytidine residue (C) is limited.
- AA and AA TT or TC and limited portion has preferential, to a length of 19 to 21, particularly 19 nucleotides, and therefore has the general form AA (N 19-2 ⁇ ) TT AA or (N 19 _ 2 i) TC , where N stands for a nucleotide.
- Oligoribonucleotides which are complementary to a section of the target gene or the corresponding double-stranded cDNA which has the general form AA (N ⁇ 9 ) to AA (N 2 ⁇ ) are further preferred.
- oligoribonucleotides, to the N 19 - 2 ⁇ - fragment of the said regions are homologous, more preferably.
- the particularly preferred oligoribonucleotides thus have a length of 19 to 21 base pairs, the single strands forming these oligoribonucleotides on the 3 ⁇ side preferably each having two additional 2 ⁇ deoxynucleotides, in particular two 2-deoxythymidine residues, so that the dsRNA 19 to 21 base pairs and comprises two protruding 2 ⁇ - deoxynucleotides per strand.
- the target gene does not contain any area of the form AA (N ⁇ 9 - 2 ⁇ )
- a search is made for areas of the form NA (N ⁇ 9 _ 2 ⁇ ) or any fragment of the form N 19 - 2 ⁇ .
- N ⁇ 9 - for example, are limited by AA and TT ⁇ 2 fragments are preferred, in principle, however, all dsRNA fragments are useful in this invention are homologous to the target sequence.
- FIG. 1 shows the single-stranded cDNA of the matrix metalloproteinase 1 (SEQ ID NO 1) in which all fragments of the form AA-N i9 -TT and AA-N 19 -TC are optically highlighted. These fragments (targeted region) are shown in FIG. 2 together with the corresponding homologous (senseRNA) and complementary (antisenesRNA) RNA single strands. Shown are single-stranded RNAs which are modified on the 3 ⁇ side by two deoxythymidine residues (dt). The hybridization of two complementary single-stranded RNAs results in dsRNA with protruding 3 ⁇ ends, which are each formed by two 2-deoxythymidine residues.
- SEQ ID NO 1 matrix metalloproteinase 1
- the matrix metalloproteinase 1 gene is one of the preferred target genes for the oligoribonucleotides according to the invention. Accordingly, oligoribonucleotides which are homologous to the double-stranded sequence derived from SEQ ID NO 1, sections thereof and in particular to the double-stranded sequences derived from the sections highlighted in FIG. 1 are particularly preferred according to the invention.
- the double-stranded sequence derived from SEQ ID NO 1 is understood to mean the sequence which is formed from SEQ ID NO 1 and the strand which is complementary thereto. The other information is to be understood accordingly. Particularly preferred are oligoribonucleotides that are homologous to the region from position 601 to 1441 of SEQ ID NO 1, very particularly prefers those that are homologous to the range from position 1099 to 1121.
- the single-stranded cDNA of elastase 2 (SEQ ID NO 59) can be seen in FIG. Again, a preferred sequence range, i.e. highlighted a 19 nucleotide sequence region flanked by AA and TT. Oligoribonucleotides which are homologous to the double-stranded sequence derived from SEQ ID NO 59, sections thereof and in particular to the double-stranded sequence which is derived from the region highlighted in FIG. 2 are likewise preferred according to the invention.
- FIG. 4 shows the single-stranded cDNA of hyaluronidase 2 (SEQ ID NO 61), preferred sequence regions again being marked. Oligoribonucleotides which are homologous to the double-stranded sequence derived from SEQ ID NO 61, sections thereof and in particular to the double-stranded sequence which is derived from the regions highlighted in FIG. 3 are likewise preferred according to the invention.
- oligoribonucleotides according to the invention could advantageously also be integrated into expression vectors, in particular those which bring about an expression of the oligoribonucleotides in mammalian cells. In this way, a stable inhibition of the expression of the target gene can be achieved even with an intracellular degradation of the oligoribonucleotides, since oligoribonucleotides are constantly supplied by the vector-assisted synthesis.
- One or more copies of a dsRNA can be integrated into a vector, but also one or more copies of two or more different dsRNAs. Suitable vector systems are described, for example, by Brummelkamp et al., Loc. Cit.
- Mammalian expression vectors are preferred, in particular those which contain a poly- merase III HI RNA promoter and 5 to 9 so-called loops, which are formed from a dsRNA according to the invention and a sequence of the same length, which is reverse complementary to the dsRNA according to the invention and serves as a spacer, and contain a termination signal of 5 successive thymidine residues ,
- the vectors thus contain 5 to 9 copies of the respective dsRNA molecule.
- These can be dsRNAs that are specific for 1 target gene or dsRNAs that are specific for several different target genes.
- the oligoribonucleotides according to the invention can be in the form of the unmodified oligoribonucleotides. However, they are preferably oligoribonucleotides which are chemically modified at the level of the sugar residues, the nucleobases, the phosphate groups and / or the skeleton located between them, in order, for example, to increase the stability of the oligoribonucleotides in cosmetic or dermatological preparations and / or in the skin , e.g.
- Oligoribonucleotides in which one or more phosphate groups are replaced by phosphothioate, methylphosphonate and / or phosphoramidate groups, such as N3 '-P5'- phosphoramidate, are exchanged are preferred. Oligoribonucleotides in which phosphate groups are replaced by phosphothioate groups are particularly preferred.
- One or more of the phosphate groups of the oligoribonucleotide can be modified. In the case of a partial modification, terminal groups are preferably modified. Oligoribonucleotides in which all phosphate groups have been modified are but particularly preferred. This applies mutatis mutandis to the modifications described below.
- Preferred sugar modifications include the replacement of one or more ribose residues of the oligoribonucleotide with morpholine rings (morpholine oligoribonucleotides) or with amino acids (peptide oligoribonucleotides). All of the ribose residues of the oligoribonucleotide are preferably replaced by amino acid residues and in particular morpholine residues.
- Morpholine oligoribonucleotides in which the morpholine residues are linked to one another via sulfonyl or preferably phosphoryl groups are particularly preferred, as can be seen in formula 1 or 2:
- B represents a modified or unmodified purine or pyrimidine base, preferably adenine, cytosine, guanine, or uracil,
- X stands for 0 or S, preferably 0,
- Y represents 0 or N-CH 3 , preferably 0,
- Z stands for alkyl, O-alkyl, S-alkyl, NH 2 , NH (alkyl), NH (0-
- Alkyl N (alkyl) 2 , (alkyl) (O-alkyl), preferably N (alkyl) 2 , where alkyl for linear or branched alkyl groups with 1 to 6 preferably 1 to 3 and particularly preferably 1 or 2 carbon atoms.
- Formulas 1 and 2 each represent only a section of an oligoribonucleotide chain.
- Morpholine oligoribonucleotides in which the morpholine residues are connected to one another via phosphoryl groups are very particularly preferred, as shown in Formula 2, in which X is 0, Y is 0 and Z is N (CH 3 ) 2 .
- the ribose residues can be modified by amino residues, such as NH 2 , fluorine, alkyl or O-alkyl residues, such as 0CH 3 , 2-modified oligoribonucleotides being particularly preferred.
- amino residues such as NH 2 , fluorine, alkyl or O-alkyl residues, such as 0CH 3
- 2-modified oligoribonucleotides being particularly preferred.
- Exemplary modifications are 2'-fluoro, 2'-alkyl, 2'-O-alkyl, 2'-0-methoxyethyl modifications, 5'-palmitate derivatives and 2 '-O-methylribonucleotides.
- the modification of the nucleotides of dsRNA counteracts an activation of the protein kinase PKR in the cell, which is dependent on double-stranded RNA. This avoids unspecific inhibition of translation.
- the substitution of at least one 2 'hydroxyl group of the nucleotides of the dsRNA by a 2' amino or a 2 'methyl group is particularly suitable.
- at least one nucleotide in at least one strand of the dsRNA can be replaced by a so-called "locked nucleotide” which contains a chemically modified sugar ring.
- a preferred modification of the sugar ring is a 2 '-0, 4' -C methylene bridge.
- dsRNA containing several "locked nucleotides" is preferred.
- alkyl herein preferably represents linear, branched or cyclic alkyl groups with 1 to 30, preferably 1 to 20, particularly preferably 1 to 10 and very particularly preferably 1 to 6 carbon atoms.
- Branched and cyclic radicals naturally have at least 3 carbon atoms, cyclic radicals having at least 5 and in particular at least 6 carbon atoms being preferred.
- Oligoribonucleotides containing ⁇ -nucleosides can also be used.
- Suitable base modifications are described, for example, in US Pat. No. 6,187,578 and WO 99/53101, to which reference is hereby expressly made.
- a modification of one or more pyrimidines in position 5 with I, Br, Cl, NH 3 and N 3 has proven to be advantageous.
- modified and unmodified oligoribonucleotides are described in the literature.
- production of modified and unmodified oligoribonucleotides is now also offered as a service by numerous companies, for example by Dharmacon, 1376 Miners Drive # 101, Lafayette, CO 80026, USA, Xeragon Inc., Genset 0-ligos and Ambion.
- the production of oligoribonucleotides is also described in US Pat. No. 5,986,084.
- the oligoribonucleotides can also be used in encapsulated form, for example encapsulated in liposomes. They can also be stabilized by adding cyclodextrins.
- Cyclodextrins are also known as cycloamyloses and cycloglucans.
- the cyclodextrins are cyclic see oligosaccharides consisting of ⁇ -1,4 linked glucose units. As a rule, six to eight glucose units ( ⁇ -, ß- or ⁇ -cyclodextrin) are linked together.
- Cyclodextrins are obtained when Bacillus macerans acts on starch. They have a hydrophobic interior and a hydrophilic exterior. According to the invention, both the cyclodextrins themselves, in particular ⁇ -cyclodextrin, ⁇ -cyclodextrin and ⁇ -cyclodextrin, and derivatives thereof are suitable.
- the cyclodextrin (s) are preferably used in cosmetic and dermatological compositions in a concentration of 0.0005 to 20.0% by weight, in particular 0.01 to 10% by weight and particularly preferably in a concentration of 0.1 to 5.0% by weight.
- native, polar and / or nonpolar substituted cyclodextrins are advantageous to use. These preferably but not exclusively include methyl-, in particular random-methyl- ⁇ -cyclodextrin, ethyl and hydroxypropyl cyclodextrins, for example hydroxypropyl- ⁇ -cyclodextrin and hydroxypropyl- ⁇ -cyclodextrin.
- the cyclodextrin species which are particularly preferred according to the invention are ⁇ -cyclodextrin and hydroxypropyl- ⁇ -cyclodextrin.
- Liposomes can be produced in a manner known per se using natural phospholipids, such as, for example, phosphatidylcholine from eggs, soybeans, etc., or synthetic phospholipids (cf. G. Betageri (editor), “Liposome Drug Delivery Systems”, Lancaster Techonomic Publishing Company 1993; Gregoriadis (Editor), "Liposome Technology", CRC Press). Preferred methods and materials for manufacturing Position of liposomes are described in WO 99/24018.
- Double-stranded oligoribonucleotides can also be modified to counter dissociation into the single strands, for example by one or more covalent, coordinative or ionic bonds. However, oligoribonucleotides without such modifications are preferred.
- the nucleotides in the RNA molecules can also include “non-standard” nucleotides, such as non-naturally occurring nucleotides or deoxyribonucleotides.
- those oligoribonucleotides are preferred which inhibit the expression of the respective target gene by at least 40%, preferably by at least 60%, particularly preferably by at least 80% and very particularly preferably by at least 85% compared to untreated cells. If necessary, the expression of the target gene is first induced in a suitable manner in the cells to measure the inhibition. Tumor cells from the HeLaS3 line are preferably used to determine the effectiveness of the oligoribonucleotides according to the invention.
- the oligoribonucleotides are introduced into the cells and then, if necessary after induction of the expression of the target gene, the expression rate of the target gene in these cells is measured and compared with that found in cells which have not been transfected with the respective oligoribonucleotide.
- the exact conditions for measuring the inhibition can be found in Example 1.
- oligoribonucleotides according to the invention and their salts are particularly suitable as an effective component of pharmaceutical cosmetic and cosmetic compositions, in particular those for topical use.
- the oligoribonucleotides after the compositions have been applied to the skin, inhibit the expression of the genes which are responsible for the breakdown of the connective tissue and thus prevent and reduce the degeneration of collagen, elastin and / or hyaluronic acid without side effects in this way enable effective treatment and prophylaxis of degenerative skin symptoms without showing the disadvantages of the prior art. It is believed that this effect is due to the fact that the oligoribonucleotides according to the invention are absorbed by the cells of the skin and intracellularly induce the degradation of the mRNAs of the genes mentioned by RNAi, details of the mechanism of this reaction cascade not yet being known.
