Definitions
- the present invention relates to peptides having a strong inhibitory activity of human topoisomerase II ⁇ and which find a therapeutic application in particular as antitumor.
- DNA topoisomerase II is an enzyme essential to the life of eukaryotic cells. It changes the topology of DNA by transient double-strand cutting of a DNA helix through which it passes another DNA helix. In addition to the biological interest of this enzyme, there is a pharmacological interest since it is the preferred target of many anti-tumor agents (Corbett and
- topoisomerase II peptide inhibitors which interact selectively with this enzyme and block its catalytic activity.
- Brother Gallois et al. have described, in Eur. J. Biochem., 249, 142, 1997, a fragment of topoisomerase II corresponding to the sequence 1013 to 1041 of human topoisomerase II ⁇ which has an inhibitory activity of topoisomerase II.
- the present invention aims to provide peptides which exhibit superior inhibitory activity.
- the subject of the present invention is therefore a peptide having the following amino acid sequence:
- X 6 Gly or Glu
- X 7 Leu or Glu
- pharmaceutically acceptable protected derivative is intended in particular to mean derivatives comprising N-protective groups which are pharmaceutically acceptable.
- N-protective groups are in particular the groups which protect from the N-terminal attack on exopeptidase enzymes.
- groups include acyl groups such as t-butyloxycarbonyl (Boc), tert-amyl-oxycarbonyl ( + Aoc), benzyloxycarbonyl, benzoyie, acetyl, formyl, propanoyie, butanoyie, phenylacetyl, phenylpropanoyl, cyclo pentylcarbonyl groups .
- the peptides according to the invention can be prepared in a conventional manner by peptide synthesis in the liquid or solid phase by successive couplings of the various amino acid residues to be incorporated (from the N-terminal end to the C-terminal end in liquid phase , or from the C-terminal end to the N-terminal end in solid phase) and whose N-terminal ends and the reactive side chains are previously blocked.
- the present invention also relates to a pharmaceutical composition comprising, as active principle, a peptide according to the invention.
- compositions can be used as an antiviral, antibacterial, antiparasitic or anticancer agent such as for example in the treatment of tumors, parasitic diseases such as leishmaniasis or Chagas disease or else in the treatment of respiratory tract diseases such as otitis or pneumonia.
- the prior vectorization of the peptide can prove to be advantageous insofar as it can promote contact between the peptide and the targeted cells.
- Vectorization methods are known to those skilled in the art. One of these methods is to encapsulate the peptide in liposomes such as cationic liposomes. It is known that these liposomes provide additional protection of the peptide against degradation in vivo. The slow release of the active ingredient in the targeted areas is therefore very clearly promoted.
- the first step in the transfection process of cells targeted by the peptide or in the process of releasing the peptide involves the formation of a complex between the lipid wall of the liposome and the peptide.
- the peptide After fusion of the respective membranes of the liposome and the cell, the peptide is released into the cytoplasm.
- liposomes The preparation of such liposomes is described in detail in "Liposome technology", Gregoriadis (CFC Press, NY 1984) or also in “Liposomes”, Ostro (Macel Dekker, 1987) or even in the publication of Lichtenberg et al. published in "Methods Biochem. Anal. 33: 337-462, 1988).
- the peptide is either dispersed, or contained, or otherwise trapped in corpuscles consisting of concentric aqueous layers adhering to lipid layers. either contained in the aqueous phase, or contained in the lipid phase and optionally in each of the two phases according to its solubility.
- the lipid phase can notably include phospholipids such as lecithin or sphingomycelin, steroids such as cholesterol, surfactants such as diketylphosphate, stearylamine, phosphatidic acid and / or other hydrophobic materials, the diameter of the liposomes preferably varies between 15 nm and 5 ⁇ m. .
- compositions of the invention is carried out in a conventional manner and depends on the mode of administration envisaged.
- the peptides optionally incorporated into a vector are administered transdermally, transmucosally or intratumorally.
- the compositions of the invention are preferably in the form of injectable solutions or suspensions.
- the pharmaceutically acceptable vehicle use will be made essentially of buffers, a saline solution of phosphate buffer (PBS) or any other solution provided that it has a physiologically acceptable pH.
- PBS phosphate buffer
- the active principle can also be incorporated into a matrix or a vehicle in the form of a hydrated gel, for example a gel based on a propylene oxide-ethylene oxide copolymer which is liquid below room temperature and gelatinous at an equal temperature. or higher than room temperature. Before administration, the gel can be optionally thinned.
- the peptide can alternatively be formulated in a sustained-release composition. Such compositions have been described in the literature. To this end, the peptide can in particular be combined with polymers of polylactic acid.
- compositions can be applied locally by direct injection or released from implants or else distributed locally using an appropriate pump.
- the present invention also relates to a method of treating a patient presenting with a tumor, which comprises the administration to this patient of an effective amount of a peptide according to the invention.
- the amount of peptide to be administered depends on the cancer pathology of the subject to be treated, the severity (presence or absence of metastases) of the disease, the chemotherapy protocol selected, the choice of a first or second intention treatment and the duration of treatment, as well as general conditions of the patient.
- the daily doses can be between 0.1 mg / kg and 10 mg / kg per day or per week depending on the number of treatment cycles of each course.
- the deprotected peptide is then filtered to separate it from the resin and precipitated in cold ether).
- the peptide was purified by HPLC with a Beckman System Gold reverse phase apparatus on a Spherisorb C- ⁇ 8 column (25x1 cm, 2 ⁇ m and 300 ⁇ ) with a linear gradient from 0 to 100% acetonitrile / water (with 0.1% TFA) over 45 minutes, the flow rate being 4 ml / min.
- the fractions having simultaneously maximum absorption peaks at 220 and 274 nm are then characterized by analytical HPLC and the fractions containing the pure peptide are grouped and lyophilized.
- Example 1 completely inhibits the activity of human topoisomerase II ⁇ and that of yeast in the two tests at a concentration of 0.5 ⁇ M.
