FIBLD OF THE INVBNTION [002] The present invention relates to compositions and methods for the treatment and prevention of disease in a mammaL In particular, the invention relates to medicaments comprising various novel oligomerio compounds and pharmaceutically acceptable salts thereof The compounds of the invention may optionally be administered with at least one of a pharmaceutically acceptable exciplent, pharmacologically active agent or a combination thereof. BACKGROUND OF THE INVB1TION [003] The 1950s-1970s saw the discovery of multiple classes of antibiotics, and their development into drugs changed a simple bacterial infection from life threatening to trivial. Thid golden age of antibiotics engendered such optimism that it was commonly thought bacterial infections would be rapidly eliminated as a cause of mortality. Unfortunately, bacterial resistance to all classes of antibiotics soon appeared. Now, three decades after the end of this era, drug resistant bacteria are ubiquitous in hospital settings and annually 90000 people die of such infections each year in the US alone. One quarter of the bacteria that most frequently cause hospital-acquired infections are resistant to the preferred antibiotic treatment, and an alarming 70% of hospital acquired infections are resistant to at least one antibiotic. 10041 Methicillin-resistant Slaphylococcus aureus (MRSA) is the most common drug resistant bacteria in hospitals, accounting for greater than 30% of all nosocomial infhotions. MRSA can also be community-acquired, causing severe illness and even death. Furthermore, the incidence of extended spectrum-lactamase (ESBL) production in clinical Klebsiella isolates has increased steadily in the past several years, severely curtailing the effectiveness of lactam la antibiotics. Perhaps most disturbing is the recent estimation that one third of enterococci in intensive care units are resistant to vancomycin, often viewed as the antibiotic of last resort. 1005] The list of drug-resistant pathogens is extensive and growing. These bacterial infctions are of particular concern in elderly, Infim, or immuno-compromised patients. Individuals with tuberculosis, AIDS, salmonellosis, gonorrhea, or malaria who contract drug resistant bacterial infections experience longer hospital stays and have mortality rates more than twice as high as those with antimicroblal-susceptible infections. Thus, resistant bacteria not only complicate medical treatment, but also add billions of dollars to medical costs every year. [006] The problem of bacterial resistance to antibiotics is exacerbated by the downward trend in antibacterial discovery and development. There has been a 56% decrease over the last two decades in the annual number of antibiotics approved by the FDA. In fact, only six antibiotics produced by large pharmaceutical companies are currently in late stage clinical trials, and all of these are derivatives of known antibiotics. Although the reasons fbr the halting of many antibacterial programs at major pharmaceutical companies are myriad, the acute (not chronic) nature of most bacterial infections and the public expectation for no side effects has made antibacterial research less profitable and more difficult when compared to other disease areas. [007] The research activity in this area has mainly concentrated on the design and in vitro studies of amphiphilic helical beta-peptides with antimicrobial activity. In view of their high propensity for helical conformations as well as their resistance to proteolytic degradation, beta-peptides represent promising antibacterial candidates. [0081 Antimicrobial peptides that adopt cationic amphiphatic a-helical structures upon binding to cell membranes (e.g., mollitin from bee venom, magainins from frog skin, cecropins from porcine small intestine) are ubiquitous in nature (Antimicrobial Sequences Database, http://www.bbm.units.it/~tossi/pagl.htm) and represent important effectors molecules of innate immunity. These peptides generally cause cell death by a two step mechanism involving interaction with the lipid component of the membrane (while in bacteria the outer leaflet of the membrane is essentially composed of lipids with negatively charged phospholipid headgroups, it is almost neutral in plants and animals) followed by membrane permeabilization. Several mechanisms for membrane permeabilization have been postulated including transient pore formation ("barrel-stave model) or detergent-like disruption of the 2 membrane ("oarpet model"). The lytic activity of amphiphillo antimicrobial peptides is strongly influenced by properties such as helix stability, anphiphilioity (hydrophobic moment), hydrophobicity, relative width of the hydrophilic and hydrophobic faces of the helix as well as net charge. Despite many structuro-activity studies, lead optimization remains challenging because sequence modifications of a-peptides generally affect several parameters at the same time. In addition, low activity on human cell membranes is a prerequisite for a oell-lytio peptide to be of therapeutic value and de-novo design of helical membrane".yti6 peptides with high membrane selectivity necessitates an even fner tuning between these five different parameters. [0091 Both the 31 and 2.512 helical backbones have been ibund suitable for the design of antimicrobial 0-peptides. In order to cluster polar residues on one face of the helix, amphiphilio 3 1 4 -helioal -peptides have been constructed from hydrophobic-cationic hydrophobic- or hydrophobic-hydrophobio-cationic residue triads. [0010] Some P3-nonapcptides with a C-terminal amide were fund to be active against Gram-Positive (S. Aureus and B. Faecium strains were clinical isolates resistant to penicillin and vancomycin, respectively) and Gram-negative bacteria with MIC values (in the range 1.6-12.5 mg/mL) comparable to that of the antimicrobial a-peptides melittin and [Ala8,13,18]-magainin II amide (a highly potent synthetic analogue of natural magainin II). Although some of these compounds show no helix formation in water, they generally display a maximum helicity in 40% aqueous TFE, a solvent system which is also known to promote helicity of amphiphilic ot peptides.

The rate of release from this dosage form is controlled both by diffusion from the swollen tablet mass and by erosion of the tablet surface over time. The rate of release may be controlled both by the amount ofpolymer per tablet and by the inherent viscosities of the polymers used. 1001271 Dyes or pigments can be admixed to the tablets or coated tablet coatings, for example for identification or characterization of different doses of active ingredient.

The synthesis method is the same as the one known for alpha-peptides. [00143] The preparation of N-protected y-amino acids is already described in prior art (Hintermann et al., Helv. Chim. Acta 1998, 41, 983-1002). [00144] According to an advantageous embodiment of the invention, the y-amino acids are prepared according to Smrcina et al., Tetrahedron, 1997, 53, 12867-12874). 1001451 The N-Boc-protected y-amino acids used for the implementation of the process of the invention are produced from the coresponding natural co-amino acids. The amino acid is first transformed by acylation with Meldrum acid in presence of carbodiimide (example: EDC) and 4 dimethylamino pyridine. After reduction with NaBH 4 , in a mixture of dichloromethane and acetic acid, the compound as obtained is oyclized in pyrrolidone in toluene at I 10*C for 4 hours. 23 After the opening of the cycle in basic medium (NaOH In MeOH), the y-amino acids are obtained with yields comprised from 15 to 60%. [00146J The preferred y-amino acids are the following: OH boo OH1 "y-Ala" "y-Val"--Lu OH boo OHO 00 -Ph" -Tyr(Bn)" y-Trp(For)" 'y-Lys(Z)" "-Arg(Tos)" [001471 The assembling of the peptide chain is then carried out with a peptides synthesizer in semi-automatic mode on a MBHA (4-methylbenzhydrylamine) resin of polystyrene type and on a scale of 25 micromole. The N-Boo-protected y-amino acids (3 equiv) are used instead of standard Boo-amino acids and they are incorporated by using the classic coupling procedure with a mixture ofBOP (benzotriazol-1-yloxy-tris (dimethylamino) phosphonium 24 [00148) hexafluorophosphate)/HOBt (1-hydroxybenzotriazole)(3 equiv/3 equiv). in presence of diisopropylethylamine (12 equiv) in order to carry out the in situ neutralisation. A double coupling is systematically carried out. The end of the coupling reaction is checked out by a Kaiser test with ninhydrine. At the end of the synthesis, the resin is washed with dichloromethane, and ether, and it is dried under vacuum. The peptide/resin is then cleaved by a treatment with HF hydrofluorico acid) for an hour and the peptide is precipitated with other to give the crude peptide, which is then purified with HPLC and lyophilised. The identity of each peptide is controlled by mass spectrometry. The purity of synthesized peptides is greater than 94% on the basis of HPLC analysis on a inverse phase column of type C18 and by using a mixture water/acetonitrile. [001491 Mol- 1, Mol-2, Mol-3, Mol-4, and Mol-5 (Z = NS) [00150] The assembling of the peptide chain is carried out with a peptides synthesizer in semi-automatic mode on a MBHA resin ofpolystyrene type and on a scale of25 micromole. The N-Boo-protected y-amino acids (3 equiv) are incorporated by using the classic coupling procedure with a mixture BOP/HOBt (3 equiv/3 equiv) in presence of diisopropylethylamine (12 equiv) in order to carry out the in situ neutralisation. A double coupling is systematically carried out. The end of the coupling reaction Is checked out by a Kaiser test with ninhydrine. The Boo group is eliminated after the coupling by a treatment with TFA (trifluoroacetio acid). [00151) The following monomers are succinimidyl or paranitrophenyl carbanates which are derived of protected diamines prepared according to (1)- Kim, J. M.; Bi, Y.; Paikoff S. J.; Schultz, P. G., Tetrahedron Let., (1996) 37, 5305, (2)- Boeijen, A., van Ameijde, J.; Liskamp, R. M. J., J Org.

[00152] The coupling of these -monomers is generally carried out in DMF (dimethylformamide)(4 equiv, 2 x 2 hours in DIBA (diisopropylethylamine)(4 equiv)). After deprotection of the last Boo group, the resin is treated with isopropyl isocyanate in the same conditions. [00153] At the end of the synthesis, the resin is washed with dichloromethane, and ether, and it is dried under vacuum. The peptide/resin is then cleaved by a treatment with HP for an hour and the peptide is precipitated with other to give the crude oligomers Mol-1 to Mol-5, which are then purified with HPLC and lyophilised. The identity of each peptide is controlled by 25 mass spectrometry. The purity of synthesized peptides is greater than 94% on the basis of HPLC analysis on a inverse phase column of type C18 and by using a mixture water/acetonitrile.

[00155] In vitro susceptibility of aerobic bacteria [00156] Material and method [00157] Four strains were selected : Escherichia Coli ATCC 25922, Staphylococcus Aureus ATCC 25923, Pseudomonas Aerughiwsa ATCC 27853 and a clinical isolated methicillin resistant Staphylococcs Aureus strain. Antibacterial activity of the molecules was tested by dilution method in Mueller-Hinton broth in order to determine the minimal inhibitory concentration (MIC) and the minimal bactericidal concentration (MBC). At least two independent assays were done. Stock solutions were obtained by solubilizing molecule powders in distilled water at concentration of 2.56 mg/mL and serial 2-fold diluted solutions were prepared. Bacterial inoculum was standardized by using direct suspensions of colonies from overnight growth in saline adjusted to a turbidity matching the 0.5 McFarland standard, and diluted to obtain a density comprised between 10 CFU/mL and 10 CFU/mL. Tubes containing 900 pL of inoculum with 100 sL of molecules solutions were incubated in air at 37*C for 18 to 20 hours. Purity and inoculum density as well as percentage of viable bacteria in limpid tubes were checked by plate counting on sheep blood agar. Broth not containing any molecule solution was inoculated with each selected bacterial strain as a control for organism viability (growth control). The susceptibility of S. Aureus strains against vancomycin was used as an internal control as well as the activity of melittin. [001581 Table 1.
