Definitions
- the subject of the present invention is a new protein-rich peptide having antibacterial and antifungal properties, compositions which can be used in agriculture and in human or animal therapy containing this peptide as active material.
- the invention also relates to methods of treating plants using these compositions as well as methods of preparing this peptide.
- insects have an effective resistance against bacteria.
- This defense is largely based on the rapid synthesis of several families of peptides. This defense is due to the rapid synthesis of several families of peptides with a broad spectrum of activity. This synthesis is induced by a septic injury or by the injection of a small dose of bacteria.
- the antibacterial peptides induced the best characterized are the cecropins and defensins of insects.
- Several other antibacterial peptides have been partially characterized.
- Scorpions are animals older than insects on a philogenic level.
- a first aspect of the invention relates to the peptide of formula I:
- the molecule of formula I will be called androctonine.
- This molecule contains 4 cysteine residues engaged in two intramolecular bridges.
- Another aspect of the invention relates to a first method for obtaining and isolating the above peptide, which is characterized in that successively: a) the hemolymp of the scorpion Androctonus australis is taken; b) the extraction is carried out by bringing the hemolymph of Androctonus australis obtained previously into contact with an acid medium with stirring, then by centrifugation; c) the supernatant is fractionated with separation by washing of the hydrophilic molecules and elution of the hydrophobic molecules by suitable elements on a separating column d) the extracts are purified. e) characterizing the peptide.
- the hemolymph is removed by cuticular incision. It is collected in a tube containing a protease inhibitor. After centrifugation to remove the blood cells, the plasma is stored at -30 ° C.
