Description:
FIELD OF THE INVENTION 
     The present invention relates to traumatic acid salts for the treatment of cutaneous pathologies where it is important to associate a bacteriostatic, antibiotic, antifungal or an antiviral activity, to the cicatrizant effect, typical of traumatic acid. 
     PRIOR ART 
     In spite of its thinness, skin plays a key role in the protection of the human organism from the external environment, in fact life is not possible when a large area of the skin mantle is seriously damaged, as in the case of various burns. 
     This global role of protection acts in different ways which, individually considered, represent as many skin functions. 
     Skin offers a remarkable resistance to traction, not only thanks to horny layer cells interdigitation and to the presence of an abundant collagen filling in dermis, but also thanks to the peculiar organization of the fibrous structure containing the elastic tissue. Thanks to these characteristics, skin performs a mechanical protection against traumatic insults and a function of a two way barrier. In fact it allows the dispersion of water (perspiratio insensibilis) and of catabolism products that are secreted by glands and conversely hampers the penetration of chemical substances, microorganisms of radiations present in the environment. Moreover skin plays a key role in maintaining both the thermal and pressor homeostasis and has functions of deposit and synthesis. Finally skin has two very important characteristics namely, the sensorial function, as it is the center of pselaphesia and of the immunological sensitivity, since it is the immunocompetent cells center. 
     Cutaneous integrity maintenance allows therefore to conserve unchanged the above mentioned physiological functions. Traditional medicine has recognized over the centuries numerous plants used in the form of extracts or decoctions able to aid the healing of wounds. 
     Still now aloe infusions and decoctions are used because of their antiphlogistic, astringent and cicatrizant effect in the treatment of burns while Asian centella and tricticum vulgaris extracts are still used for the preparation of pharmaceutical products used for the cicatrization (M. Rodriguez-Bigas et al., Comparative Evaluation of Aloe Vera in the Management of Burn Wounds in Guinea Pigs, Plastic and Reconstructive Surgery, 1988). 
     In the last years a growing interest has been developed in the attempt to isolate and to identify the substances responsible For the pharmacological effect with the aim to understanding the difficult pharmacology of the vegetal extracts. 
     Traumatic acid owing its name to its property to repair damages in the vegetal tissue has been indicated as the active principle in the tricticum vulgaris extract and in the aloe vera infusion and as such it was the object of numerous patents. (Pacini, U.S. Pat. No. 3,720,773, &#34;Cobaltous trans-traumatate for topical treatment of herpetic keratitis&#34;). Chemically speaking traumatic acid or 10-dodecendioic is a linear long chain dicarboxylic acid having 12 carbon atoms and an unsaturated bond: the anti-irritant activity of the traumatic acid seems to be due to the carboxylic group distribution along the carbon chain (R. L. Goldemberg et al., Reduction of topical irritation, J. Chem. Soc. , 28, 667-679. 1977). Traumatic acid identification was described for the first time by English and Bonnernel (The Wound Hormones of Plants, The Journal of Biological Chemistry, vol. 121, No.2, 1937), is a vegetable hormone specifically produced by several plants as the reaction to the damage of their tissues and it is able to induce the cellular proliferation and differentiation necessary to heal wound and to create the physiological stimulus for the healing of continuous solutions. 
     Traumatic acid is formed in plants by oxidation of linoleic acid to 3-peroxylinoleic acid, which is subsequently transformed into the Final product by enzymatic route thanks to the action of hydroperoxy-lyase (Zimmerman D. C., C. A. Condron, Identification of Traumatin, a Wound Hormone, as 12-Oxo-trans-10-dodecenoic Acid, Plant Physiol. 63,536-541, 1979). 
     The same ability to heal wounds has been recognized in the experimental animal wherein the trans-traumatic acid demonstrated (when administered by topical route) a reepithelializing and antiirritant action and furthermore showing effectiveness on an in vivo herpetic keratitis model both after topic and systemic administration. 
     (I. Miyamoto et al., Effects of cosmetics containing bioactive substances on skin, J. Soc. Cosmet. Chem. Japan, Vol. 22, No.4 1989). 
     These pharmacological effects were subsequently reconfirmed in man, where traumatic acid is proposed for burns therapy since it reduces the reepithelialization times, probably increasing the hydration layer of the cutaneous tissue, promoting cohesion between keratinocytes, reducing the edematous condition since it promotes the water transepidermic passage, and finally increasing the cells metabolism in the lesion area. 
     Positive clinical results were also observed in psoriatic patients or in patients affected by acne, dermatitis seborrheic, neurodermatitis and itches of various origin but also by diseases of vital origin as for example trachoma, herpetic keratitis, verruca (Pacini 1973). With reference to the above mentioned pathologies, it is important to rely on a drug that together with the cicatrizant and lenitive activities has an antiseptic and/or antibacterial activity and therefore broadening the traumatic acid action pattern. 
     THE PRESENT INVENTION 
     The applicant has unexpectedly found that trans and cis traumatic acid salts of formulae (I) and (II) ##STR1## wherein B is a biologically active cation as defined in one of the following classes: 
     a) a quaternary ammonium cations of respectively general formula (III) and (IV) ##STR2##  wherein R 1 , R 2 , R 3  and R 4  are equal or different from each other and are selected from: 
     i) a linear or branched alkyl radical having from 1 to 20 carbon atoms optionally containing in the aliphatic chain at least one of the following groups:arylenoxy, alkylenoxy, and being optionally substituted in the aliphatic chain with at least one of the following residues: aryl, aryloxy and alkoxy groups; 
     ii) a cycloalkyl radical of from 3 to 10 carbon atoms;

     iv&#39;) antifungal activity, 
     d) is a cation of a metal selected From silver and zinc, not only retain the peculiar capacity of the traumatic acid or of the considered cation, but these characteristics are associated and enhanced. 
     These specific properties are to be considered of special interest because many antiseptic substances when topically used do not facilitate but often inhibit wound healing.

     BIOLOGICAL ACTIVITY 
     For purposes of clarity the product tested in the following pharmacological trials are those prepared as described in the above reported chemical preparations examples. Therefore they are all salts of trans-traumatic acid. 
     These trials have the aim to evaluate both the cicatrizant activity of these compounds with respect to that of traumatic acid and the antibacterial activity with respect to a comparison molecule having the same activity in suitable trials carried out in vitro. 
     1. Effect of cellular proliferation evaluated on fibroblasts of the traumatic acid salts. 
     Experiments on 3T3 fibroblasts 
     1.1a Materials and methods. 
     Cells preparation 
     Mice 3T3 fibroblasts cultures sown at a 40.000/ml concentration on plates having 6 wells in a DMEM culture medium enriched with 10% calf serum are used. After 24 hours culture, the 90 prepared wells are divided in order to allow the analyses of the compounds of the invention, every compound to be tested being used respectively at a concentration of 0.1, 1 and 10 μg/ml by subsequent evaluations after 48 and 72 hours of incubation. 
     Compounds solubilization: 
     Hexadecyltrimethylammoniun (ETA) traumatare: solubilized in water and brought to the desired final concentrations of 0.1. 1 and 10 μg/ml by progressive dilutions; 
     Ethanolamine traumatate: solubilized in water and brought to the final concentrations of 0.1, 1 and 10 μg/ml by progressive dilutions; 
     Traumatic acid: neutralized with sodium hydroxyde and solubilized in water, then brought to the final concentrations of 0.1, 1 and 10 μg/ml by progressive dilutions with the culture medium. 
     The compounds are added to the cells after 24 hours culture. The cells number is measured by colorimetry with the neutral red intravital stain after 24, 48, 72 hours of incubation. 
     Results: 
     These compounds act according to a dose--effect relation. Particularly hexadecyltrimethylammonium (ETA) traumatare, ethanolamine traumatare, and traumatic acid at 0.1 μg/ml concentration are able to affect cells proliferation according to a not statistically significant trend. At the concentration of 1 μg/ml hexadecyltrimethylammonium (ETA) traumarate&gt;ethanolamine traumatare=traumatic acid are able to increase cellular proliferation. At the highest concentration (10 μg/ml) the compounds tend to reduce or at least not to increase cellular proliferation. From a biological standpoint the compounds give more significant results after 48 hour (table 1.1-a), although already after 24 hours a higher effect is observed if compared to that obtained with control cultures. A side control experiment is also carried out in which the cultures confluence is evaluated: the cultures treated with hexadecyltrimethylammonium traumatare and ethanolamine traumatare&gt;traumatic acid reduce the time normally necessary for the cells to reach the confluence. 
     These data demonstrate that these compounds are able to stimulate cicatrization processes. 
     1.1b Materials and methods 
     Cell growth 
     Mouse Balb/C 3T3 fibroblasts were grown in DMEM medium supplemented with penicillin (100 units/ml) and streptomycin (0.1 mg/ml). For experimental purposes, cells are routinely inoculated in 6.4 μm diameter culture dishes (5000cells/dish) and cultured overnight. After 24 hours the culture medium was decantated and the compounds to be tested are added in the presence of 10% foetal calf serum (FCS). 
     The cells are incubated at 37° C. in 5% CO 2  air for 4 (t0), 24 (t1) and 48 (t2) hours before cell density measurement by colorimetry using crystal violet (exposure for 15 minutes, room temperature, absorbance 570nm). 
     Compounds solubilization 
     The compounds to be tested are solubilized in DMEM+10%FCS and DMSO to obtain the final concentration of 10 -5  M, 10 -6  M e 10 -7  M in 0.05% DMSO. 
     Results 
     The cells number is measured 4, 24 and 48 hours after seeding. The cell growth is evaluated as t2/t1 ratio (%). The results described in table 1.1-b show that lincomycin traumatate&gt;rolitetracycline traumatate&gt;erythromycin traumatate are capable to promote cell growth at all the tested doses and this effect appears more consistent if compared to the corresponding one of the parent compound traumatic acid. 
     1.2 Mice fibroblast L 929 cell culture 
     Materials and methods 
     Cell growth 
     Mice fibroblast cells L929, clone derived from connective tissue, are suspended in Eagle&#39;s MEM with penicillin (100U/ml)--streptomycin (0.1 mg/ml), seeded in culture dishes (10000cells/dish) and cultured overnight. After 24 hours the culture medium was decantated and the tested compounds are added. The cellular density is measured after 4 (t0) and 24 (t1) hours of incubation at 37° C. in 5% CO 2  air by colorimetry using crystal violet (exposure for 15 minutes, room temperature; absorbance 570 nm). 
     Compounds solubilization 
     The compounds Benzethonium traumarate, gentamycin traumatare acid are solubilized in water at the concentration of 10 -6  M, 10 -7  M and 10 -8  M, while traumatic acid was solubilized in DMSO at the above mentioned concentrations. 
     Results 
     The cells number is measured at 4 (t0) and 24 (t1) hours from the seeding. The cell growth is evaluated at t1/t0 rate (%). The results described in table 1.2 show that benzethonium traumatare&gt;gentamycin traumarate ape capable to promote cell growth (proliferation) according to dose-effect relationship and this effect is higher than traumatic acid effect. The above experimental data indicate that the salification process can also increase the proliferative effect in comparison with parent compound. 
     2. Antibacterial activity of the traumatatic acid salts 2.a diffusion method in agar-germs 
     Materials and methods 
     Bacterial suspention preparation: 
     In a Tryprone Soy Agar diffusion medium ATCC (American Type Culture Collection) standard bacterial strains are inoculated, preparing a final solution of 10 6  cfu/g (colony forming unities) of the following strains: 
     
         ______________________________________Pseudomonas Aeruginosa ATCC 35422Cepacia                ATCC 25416Maltophilia            ATCC 13637Staphylococcus Aureus  ATCC 65380Staphylococcus Epidermidis                  ATCC 14990Streptococcus Fecalis  ATCC 29212Escherichia Coli       ATCC 35248Candida Albicans       ATCC 10231Aspergillus Niger      ATCC 16404______________________________________ 
    
     Plates preparation 
     Every plate contains 20 ml of a medium where 2 equidistant wells having a standard diameter are Formed and in each of these wells 200 μg of the above described bacterial solution are inoculated. 2 plates are prepared for every couple of compounds to be tested at different concentrations, and For every strain, and each of these plates is compared with a white (sterile demineralized water inoculum). After the inoculum, the plates are placed in the refrigerator to favour diffusion and temporaneously blocking bacterial growth. 
     The compounds hexadecyltrimethylammonium traumatate and benzyldimethylhexadecylammonium traumatare respectively versus hexadecyl trimethylammonium bromide and benzyldimethylhexadecylammonium chloride are solubilized in demineralized water to Form solutions at the concentrations: 0.1; 0.5; and 1%. 
     Parameters 
     The antibacterial effect is evaluated by measuring bacterial diffusion halo around the well vs white (halo absence). 
     Results 
     The analysis of the results evidences that the two compounds of the invention hexadecyltrimethylammonium traumatare and benzyldimethylhexadecylammonium traumatare have an antibacterial and bacteriostatic activity profile comparable to that of the comparison products hexadecyltrimethylammonium bromide and benzyldimethylhexadecylammonium chloride, indicating that the salification has not altered the original biological properties (Table 2. a).

     Evaluation of Bacteriostatic Minimal Concentration (BMC): 
     50 μl of bacterial suspension are added to the tube containing the compounds to be tested and incubated at 37° C.: the densitometric determination is made in comparison with Mc Farland standard solution 24 and 48 hours later. 
     After the incubation time the suspensions ape gently agitated; 50 μl of each suspension are inoculated in tubes containing 5 μl of TSB and incubated at 37° C.; the densitometric determination is made 48 hours later. 
     BMC is defined by comparison between the two densitometric evaluation. 
     Results 
     All the examined compounds show bacteriostatic effect as described in Tables 2.b)1-6. This effect is specific for the different bacterial strains tested. The bacteriostatic effect of each salt is similar to stechiometric concentration of the respective negative ion. 
     The above experiment suggest that the new salts of traumatic acid here described, capable to promote cell proliferation as shown before, possess also bacteriostatic effect. Furthermore the above experiment show that the salification process does not alter the specific effect that the anion contribute.

     Conclusions 
     The reported results clearly evidence that the compounds of the present invention by salification of traumatic acid are able to determine a specific and considerable cicatrizant activity associated with a marked antibacterial activity. 
     These effects may be advantageously used in the pathologies wherein it is desirable to associate a stimulation of tissue reparative processes with an antibacterial effect, also considering that many topical antiseptic agents used in surgical practice do not facilitate, but often inhibit injuries healing.(Meyers, Jawetz and Goldfien Farmacologia Medica chap. 58 Ed. Piccin, 1975). 
     The salts of the present inventions are therefore useful in human therapy fop the treatment of injuries and infected injuries as a consequence of a surgical operation, fistulae, necrotic processes, ulcerodystrophic alterations (torpid sores, bedsores, burns, fistulous stabs and rhagades) or, anyway, situations requiring the reaction of the process of epithelial neoformation such as acne, dermatitis seborrheic, neurodermatitis, itches also of allergic nature or dermic phenomena of intoxication without excluding affections of vital origin such as trachoma, herpetic keratitis and verrucae. Moreover pathologies are to be added being more simply related to a delayed or altered dermic layer renewal or involving alterations of the cutaneous hydrolipidic layer (e.g. cutaneous ageing, damage by make-up or cosmetics excess). 
     For these pathologies both the parenteral (vials for intramuscular use) and the topical administration (creams, ointments, gels and solutions) are foreseen. 
     The necessary dose to perform the therapeutic effect varies depending on the type and seriousness of the damage and on the considered patient (age, concomitant pathologies). A therapeutic dosage is preferable being comprised between 100 and 300 mg/die with periods variable in relation to the type of pathology and anyway not shorter than two weeks.
