Definitions
- the invention provides peptides with anti-inflammatory, anti-angiogenic and / or antimicrobial activity and their use in the prevention or treatment of inflammatory and / or angiogenesis-related diseases.
- Inflammation or inflammatory reaction is a response to an aggression of exogenous origin (infectious, traumatic cause) or endogenous (encounter of an "abnormal” or a large quantity of antigen, immunological cause, ischemi - irreperfusion syndrome). It is involved in natural immunity in response to a danger signal as well as in the induction of the specific immune response and is therefore associated with a very wide variety of pathological situations (infections, systemic diseases, cancers, thromboembolic pathologies ). The inflammatory reaction, initially intended to protect the body against external aggressions, can lead to deleterious effects.
- the inflammation can affect the structure as well as the function of the affected organ and must be treated.
- the skin and the mucous membranes are the seat of many pathologies including an inflammatory component.
- Eczema and psoriasis are examples of dermatoses characterized by an inappropriate, excessive or chronic inflammatory reaction resulting in tissue damage.
- Atopic dermatitis is a chronic inflammatory disease involving innate alteration of the skin barrier and inflammation involving innate and adaptive immunity, including specific T cells directed against environmental protein allergens (extrinsic AD or allergic) or cutaneous auto-antigens (intrinsic or non-allergic AD).
- AD atopic dermatitis
- DA seems correlated with skin colonization by Staphylococcus aureus (Lin et al., 2007 Clinic Rev Allerg Immunol; 33: 167-177).
- Psoriasis is a chronic inflammatory disease whose precise cause is not known. Several factors would be involved in the onset of the disease, especially genetic and environmental factors. Microorganisms could also be the cause of psoriasis (Munz et al, 2010. Arch Dermatol Res, 302 (7): 495-8). At the cellular level, T lymphocytes seem to play a central role. A frequent complication of inflammatory dermatoses is impetiginisation, that is to say the superinfection of skin lesions initially uninfected, most often by streptococci or staphylococci.
- Anti-inflammatory drugs include anti-inflammatory steroids (derived from cortisol or cortisone) and non-steroids (e.g., aspirin, ibuprofen), and compounds with immunosuppressive activity.
- anti-inflammatory steroids derived from cortisol or cortisone
- non-steroids e.g., aspirin, ibuprofen
- compounds with immunosuppressive activity e.g., aspirin, ibuprofen
- the most commonly used anti-inflammatory agents on the skin are topical corticosteroids such as hydrocortisone or betamethasone. There are four groups of topical corticosteroids divided according to the intensity of their activity (power level), from class I (very strong activity) to class IV (weak activity).
- the choice of activity level and dosage of the local corticosteroid depends on the nature of the lesion, the sensitivity and the age of the patient, and may require various adjustments during treatment.
- the side effects of topical corticosteroids range from skin atrophy (reversible) to the appearance of skin infections, requiring discontinuation of treatment via contact dermatitis associated with corticosteroids.
- Anti-inflammatory agents are contraindicated when the skin is infected or if it presents ulcerations (wounds) and are avoided in case of infectious dermatosis or superinfection of a pre-existing dermatosis because of the risk of a low noise evolution of infectious pathology, masked by an apparent favorable clinical effect. Thus, it is often recommended to treat any skin infection prior to the application of topical corticosteroids, which further complicates the treatment.
- Antimicrobial peptides are defense peptides considered to be one of the key components of the innate immune system, which provides the first line of defense for multicellular organisms against pathogens.
- the interest aroused by these peptides comes in particular from their broad spectrum of activity. Their mode of action is based on a rapid permeabilization or fragmentation of the membranes of microorganisms, unlikely to generate the appearance of resistance mechanisms.
- Antimicrobial peptides have been identified in plants, insects, amphibians and mammals. The skin of amphibians is an important source of antimicrobial peptides and each frog species has its own peptide repertoire consisting generally of 10 to 15 PAMs.
- the Phyllomedusinae subfamily synthesizes and secretes a large diversity of PAMs that have been classified into seven families: dermaseptins (17 peptides), phylloseptins (17 peptides), plasticins (6 peptides), dermatoxins (4 peptides), phylloxins (2 peptides ), hyposines (5 peptides) and 4 orphan peptides (Amiche et al., 2008, Peptides, 29: 2074-2082).

- Example 10 In vitro study of the antimicrobial activity of DA2NE, DA2Na, K4D, L7A, K12A, K12P, V13A, A14D, A14K, M25A, DA2NEQ (D) and DA2N (D)
- DA2N SEQ ID NO: 4
- DA2NEQ SEQ ID NO: 2
- DA2NE SEQ ID NO: 3
- DA2Na SEQ ID NO: 7
- K4D SEQ ID NO: 13
- L7A SEQ ID NO: 14

- the MIC and CMB were determined according to the protocol set out in part 2.1 of Example 2.
- Example 2 Table 2 which demonstrate that DA2N and DA2NEQ exhibit antimicrobial activity on Gram-positive and Gram-negative bacteria.
- DA2NE, DA2Na, K4D, L7A, K12A, K12P, V13A, A14D, A14K, M25A, DA2NEQ (D) and DA2N (D) is shown in Table 5:
