TITLE "Derivatives of Arylsulfonamido-Substituted Hydroxamic Acid as Matrix Metalloproteinases Inhibitors" FIELD OF INVENTION The invention relates to the field of compounds that are inhibitors of proteinase, in particular of compounds of formula (I) reported hereinafter, having good solubility in water and inhibitory activity of matrix metalloproteinase, useful for the treatment of diseases associated to pathologic activity and/or overexpression of the above said enzymes, as well as for anti-ageing cosmetic treatments. STATE OF ART Matrix metalloproteinases (MMP) are a family of more than 20 different Zn- dependent enzymes, responsible for degradation of extra cellular matrix. The cellular matrix components carry out a fundamental role in modulating the cellular environment during the development, the morphogenesis and the tissue repair processes. Therefore, their activity is finely regulated, in regard to trascriptase as well as activation and also by action of endogenous inhibitors such as TIMP (Tissue Inhibitors of MetalloProteinases) and α2-macroglobulin. An alteration of the delicate equilibrium which regulates the activity of MMP's is connected to insurgence and progression of numerous pathologies such as pulmonary emphysema, rheumatoid arthritis, osteoarthritis, diabetic retinopathy, photoaging of epidermis and some kinds of tumour. Besides the above said endogenous inhibitors, many different compounds developed as synthetic inhibitors of MMP can be found in the literature. A group of inhibitors mentioned in many publications is that of compounds containing the functional group hydroxamic (-CO-NH-OH), such as the derivatives arylsulfonamido-substituted hydroxamic acid described in European Patents No. 606 046 and No. 766 672. Most of these synthetic inhibitors are not very selective, because they are able to inhibit not only one, but several MMP's. The derivatives of arylsulfonamido- substituted hydroxamic acid mentioned above, for example, are described in the European Patents No. 606 046 and No. 766 672 as inhibitors of MMP in general, and in particular as inhibitors of stromelysin (MMP-3), gelatinase (MMP-2) e collagenase I (MMP-1 ). Despite their inhibitory activity, the lack of selectivity observed for these compounds seems to be the cause of muscle-skeletal pains appearing collateral effect following to the administration of these compounds. Moreover, different therapeutic approaches showed that the active principle with optimal therapeutic results, is the one who inhibits selectively the MMP whose pathological activity is connected to a certain disease, but does not inhibit any other MMP to the same extent. It is therefore still felt providing selective synthetic inhibitors, in particular inhibitors of some metalloproteinases for which only wide spectrum inhibitors are now available. A particular case is that of metalloelastase from macrophage (MMP-12), an enzyme that is particularly active in the degradation of elastin and of the components of basal membrane like fibronectin, laminin, entactin, proteoglycans and collagen IV. Many studies have shown that there is a direct relation between the overexpression of MMP-12 and the development and progression of pulmonary emphysema (Science 1997, 277, 2002-4). Cigarette smoke and inhalation of other harmful substances, related to professional activities, favour infiltration of macrophages and induce to overexpression of metalloelastase; so that they are among the major factors of risk for the development and progression of pulmonary emphysema. The role of the MMP-12 in pulmonary emphysema is therefore ascertained. Even if there is a big therapeutic potential for this discovery - millions of people all over the world are affected from this pathology - there is still not available a selective inhibitor of MMP-12, but only wide spectrum inhibitors are known, such as batimastat and marimastat, that work on activity of this enzyme as well as on activity of several other metalloproteinases. Indeed they are reported to exhibit IC50 values of about 3 to about 16 nM against each of MMP-1 , MMP-2, MMP-7, MMP-9 and MMP-12 (Whittaker, Chem. Rev. 1999, 99, 2735-2776). Also the derivatives of arylsulfonamido-substituted hydroxamic acid disclosed in European Patent No. 766 672 are mentioned as synthetic inhibitors of MMP-12, and they are reported to exhibit IC5O values of about 1 to about 10 nM; but also in this case the compounds show inhibitory activity also against other metalloproteinases. Moreover, the lack of selectivity is generally a factor of limitation in therapeutic treatment, and it would be an advantage to have available a principle that is active only against a particular pathology and suitable to be formulated for the particular treatment of this pathology. At this aim it is important to note that the synthetic inhibitors described in the European Patents No. 606 046 and No. 766 672 generally have scarce solubility in water, which limits its use and may also limit bioavailability of the active principle. In view of what reported above, the need of novel synthetic inhibitors of MMP's, having good solubility in water, selective inhibitory activity against specific MMPs and lower inhibitory activity against other MMPs, is therefore felt. SUMMARY OF THE INVENTION Now the Applicant has found that the compounds of formula (I) hereinafter reported, besides having a good solubility in water, inhibit selectively the enzymatic activity of matrix metalloproteinases MMP-12, MMP-8 and MMP-13, whereas they inhibit for example the MMP-7 to a much lower extent. The present compounds are therefore particularly useful for the treatment of all kinds of diseases associated to a pathological activity and/or overexpression of MMP-12, for example the treatment of pulmonary emphysema, and for the treatment of periodontitis and other diseases associated to a pathological activity and/or overexpression of MMP-8 and MMP-13.

Rheoloqy modifiers Viscosity additives set up network structures throughout the base fluid, and exhibit the "yield value". Clay and polymer additives possess high yield values, and are therefore used to positively support suspension problems. Regarding particle suspension, the addition of such viscosity building agents will help to decrease the density difference between the particle and the fluid media surrounding, and therefore will lead to better resistance to the settling down of the particles. Thickeners can be divided into at least 2 general categories: those that show the best performance in water, and those that show the best performance in oils. In addition, it is also possible to differentiate them according to their nature, for example synthetic polymers, natural polymers and their derivatives, mineral polymers etc., but also according to their ionic character such as anionic, cationic, nonionic or amphoteric.

The amount of the additional bacteria-inhibiting agents present is usually from 0.1 to 2 % by weight, based on the solids content of the preparations. Perfume oils There may be mentioned as perfume oils mixtures of natural and/or synthetic aromatic substances. Natural aromatic substances are, for example, extracts from blossom (lilies, lavender, roses, jasmine, neroli, ylang-ylang), from stems and leaves (geranium, patchouli, petitgrain), from fruit (aniseed, coriander, carraway, juniper), from fruit peel (bergamot, lemons, oranges), from roots (mace, angelica, celery, cardamom, costus, iris, calmus), from wood (pinewood, sandalwood, guaiacum wood, cedarwood, rosewood), from herbs and grasses (tarragon, lemon grass, sage, thyme), from needles and twigs (spruce, pine, Scots pine, mountain pine), from resins and balsams (galbanum, elemi, benzoin, myrrh, olibanum, opoponax).

EXAMPLE 7 (COMPARISON) Preparation of 3,N-dihvdroxy-2-r(4-methoxy-benzenesulfonyl)aminol- propionamide Tcompound of formula (I) wherein Ri is CHp-CHp-OH, R? is H and R3 is OCH3I The compound was prepared as described above in the Example 1 , with the difference that 1 -acetyl-2-bromoethanol was used instead of 2,2-dimethyl-1 ,3- dioxolane-4-methanol. EXAMPLE 8 In vitro inhibition test The compounds of the invention, prepared as above described, were tested in vitro according to the method reported by Knight et al. in FEBS Lett 1992, 296 (3):263. Catalytic domain of MMP-12 was cloned, expressed and purified according to the procedure reported in Banci et al. Journal of Molecular Catalysis A: Chemical, 2003, Vol. 204-205, pp.401 -408). Preparation of catalytic domain of MMP-1 was performed as follows: proMMP-1 cDNA was cloned into the pET21 (Novagen) expression vector. The recombinant vector was transformed into Escherichia CoIi BL21 cells. The bacteria were grown in 2 XYt media and incubated at 37 °C. When the cells reached the exponential growth phase, the expression of the protein was induced by adding 0.5 mM of IPTG and the incubation was continued further for four hours. The MMP-1 catalytic domain precipitated in the inclusion bodies and these were solubilized, after lysis of the cells, in a solution of 2 M urea and 20 mM Tris-HCI pH 8. The protein was purified by using a Hiprep 16/10 (20 ml_) Q FF (Pharmacia) with a linear gradient of NaCI up to 0.5 M. The purified protein was then refolded by using a multi step dialysis against solutions containing 50 mM Tris-HCI pH 7.2; 10 mM CaCI2; 0.1 mM ZnCI2; 0.3 M NaCI. Then the protein is activated by reacting for 12 h in presence of 1 M 4-phenylmercuric acetate. The 4- phenylmercuric acetate was then removed by dialysis against a solution containing 10 mM Tris-HCI pH 7.2; 5 mM CaCI2, 0.1 mM ZnCI2; 0.3 M NaCI. To assess the enzymatic activity of the protein expressed and to test compounds of formula (I) of the invention the following polypeptide was used: Mca-Pro-Leu-Gly-Leu-Dpa-Ala-Arg-NH2 AcOH [Mca = (7-methoxy-coumarin-4-yl)acetyl; Dpa = N-3-(2,4-dinitrophenyl)-L- , - diaminopropionyl]. This substrate whose code is P-126, is a commercially available product by BIOMOL International Lp. Tests were performed in a buffer containing HEPES 50 mM, CaCI2 10 mM, Brij-35 0.05%, pH 7. The compounds prepared as above, were solubilized in dimethyl sulfoxide (DMSO) and the so obtained solution was subsequently diluted with buffer so as to reach 1% DMSO inside the cell. Experiments were carried out at 298 K by incubating the solutions at this temperature and by using a thermostatic system for the cell (Peltier). A solution DMSO/buffer in the same ratio was used as control. The protein was maintained in presence of inhibitor for 5 min before the substrate was added. Subsequently, after addition of peptidic substrate, the increase of fluorescence intensity was measured vs. time (excitation 328 nm, emission 393 nm) using a Varian/Eclipse fluorimeter. Matrix metalloproteinases cleave peptidic bond glycine-leucine separating coumarinic group from 2,4-dinitrophenol and so causing a high increase of fluorescence intensity under the conditions indicated above. Starting from concentration zero (absence of the inhibitor), subsequent measurements were carried out increasing the concentration of tested compound in the sample. The fitting of rates as a function of the inhibitor concentration provided the IC50 value for each compound. The so obtained experimental data showed the high ability of compounds of the invention to inhibit MMP-12, MMP-8 and MMP-13, and their selectivity toward this metalloproteinase, especially compared to the inhibition activity toward MMP-7. The present compounds show therefore an ideal therapeutic and pharmacological profile, in particular for the treatment of pathologic conditions where MMP-12 is involved, such as pulmonary emphysema, and where MMP-8 and MMP-13 are involved, such as periodontitis. Moreover, the present compounds of formula (I) showed to be capable to sufficiently inhibit MMP-1 too, thus suggesting their use in anti-ageing cosmetic preparations. Moreover, their good solubility in water improves the bioavailability of active principle and allows preparing stable aqueous aerosol formulations, particularly suitable for the treatment of pulmonary pathologies, such as emphysema. The IC50 value obtained for comparison compound of Example 7 showed that compounds analogue to compounds of formula (I) and having good solubility thanks to the hydroxyl group in R1 radical, do not have the inhibition activity and selectivity of present compounds of formula (I), in which R1 radical comprises at least two hydroxyl groups.
