Definitions
- the subject of the invention is a new process for extracting endotoxins from bacteria, in particular Gram-negative bacteria, as well as the use of this process for the preparation of compositions comprising endotoxins or their derivatives and intended for human or animal use (scientific, medical ).
- Endotoxins are powerful stimulants of the immune system (induction of Interleukins. TNF, NO ). They are the main constituents of the outer membranes of Gram-negative bacteria. Endotoxins are mixtures of lipopolysaccharides or LPS. Among the bacterial colonies, there are mainly two categories: those called type S, for "smooth”, relating to the smooth appearance of the colony; those called type R, for “rough”, this term recalling the rough morphology of the colony. There is also a third category called SR for “semi- rough”. The structure of the LPS constituents of bacterial endotoxins is different depending on whether they are type R or S bacteria. The LPS consist of a lipid domain called lipid A and of a polysaccharide chain, called nucleus, attached to the lipid A.
- LPS type S also has an antigenic chain called type O.
- LPS type R does not have this antigenic chain type O.
- LPS type SR has a single unit of the antigenic chain type O.
- the present invention relates more particularly to the isolation of endotoxins from a bacterial culture of type R and optionally of type S-R. However, it can also be applied to bacterial cultures of type S.
- the bacterial endotoxins were isolated by extraction using a mixture of solvents which could be a mixture of phenol and water or a mixture of chloroform, petroleum ether and phenol. These methods have the serious disadvantage of using toxic solvents and therefore entail health risks for the people who have to handle them. There is also a method of extraction with trichloroacetic acid, however this method causes too much contamination to be considered satisfactory.
- This document also describes a method for purifying natural endotoxins from isolated endotoxins according to one of the traditional methods of phenol extraction in a first step.
- the endotoxins are purified by extraction using the mixture of solvents isobutyric acid / molar NH OH (5: 3).
- the extract is centrifuged and the supernatant recovered.
- the solvents are evaporated.
- the endotoxin is recovered by trituration with ethanol.
- the method according to the invention is characterized in that: - the starting product is a set of bacterial cells, or optionally a culture supernatant; - in a first step, the bacterial cells, or the culture supernatant, are suspended in a mixture of solvents consisting of:
- the solvents are removed from the supernatant or the filtrate by any means known to those skilled in the art, such as in particular: dialysis, filtration / washing, precipitation of LPS, for example by addition of ethanol.
- the method according to the present invention has many advantages over the methods of the prior art. It is fast: the extraction of endotoxins takes 12 to 24 hours or less, while in phenol extraction processes, the extraction stage itself lasted at least a week.
- This method does not use silica, it is simpler to implement, especially on an industrial scale. This method does not use toxic solvents, so it is not dangerous for the manipulators who use it. She is very selective.
- the yields are 2 to 10 times higher than those obtained by the methods of the prior art for the bacteria already tested.
- the LPS obtained by the process of the invention have the advantage of not being a carrier of contaminants.
- Aliphatic acids comprising 4 carbon atoms are preferred, such as butyric and iso-butyric acids.
- the aliphatic acid preferentially used in the present invention is iso-butyric acid.
- aliphatic amines which can be used in the present invention, there may be mentioned in particular: ammonia, dusopropylethylamine, triethylamine.
- ammonia or triethylamine are chosen.
- Aliphatic amines are used in aqueous solution with a concentration ranging from 5 to 20%, preferably with a concentration around 10%.
- composition resulting from the first step is a heterogeneous composition comprising on the one hand particles of suspended cellular debris, on the other hand the bacterial endotoxins in solution in the mixture of solvents.
- the composition obtained from the third step of the process of the invention can be extracted (dialysate or precipitated LPS which is taken up in water) using methanol or a mixture of chloroform and methanol to remove, in particular, contaminating phospholipid or lipoprotein residues.
- the endotoxins obtained from the process of the invention can be kept in aqueous solution or lyophilized in order to store them in powder form, the latter solution having the advantage of facilitating their handling and their dosage.
- the bacterial cells used as starting material are preferably Gram negative cells.
- Cells preferably used in the process of the invention are: Bordetella pertussis, Escherichia Coli, Bordetella parapertussis, Salmonella, Shigella, Pseudomonas, Neisseria, Haemophilus.
- the bacterial cells are generally obtained by centrifugation of a culture medium and recovery of the bacterial pellet. However, during this centrifugation operation, it is possible to recover a supernatant which can be rich in lipopolysaccharides and can constitute a starting product for the application of the method of the invention.
- the preferred solvent mixtures are: isobutyric acid and either ammonia in aqueous molar solution or triethylamine in 10% aqueous solution (percentage by volume).
- a mixture of isobutyric acid and ammonia in aqueous molar solution is used in a volume ratio 5/3 or a mixture of isobutyric acid and triethylamine in aqueous solution at 10% in a volume ratio 5/3 .
- the agitation corresponding to the first step of the process of the invention lasts from 5 to 15 minutes. Even more advantageously from 10 to 15 minutes.
- the filtration is made on a support with a porosity ranging from 0.1 to 2 ⁇ m.
- this centrifugation is preferably carried out under the following conditions: 1500 to 3000 g, for 10 to 20 minutes at room temperature. Preferably 2000g for about 15 minutes.
- the method according to the present invention allows endotoxins to be obtained quickly, with very good yields and substantially free of biological contaminants or solvents. All these properties make it possible to envisage applications which until then could hardly be implemented.
- compositions intended for human or animal administration Due to the toxicity of the solvents used in the prior art and the purification difficulties which they entailed, such applications were not conceivable. Thanks to the process of the invention, it is now possible to prepare compositions, in particular therapeutic compositions, which can be administered to humans or to animals (subject to the non-toxicity of the molecules themselves) by all routes: oral, injection, application to the skin or mucous membranes.
- vaccine compositions comprising endotoxins, or endotoxin derivatives, on an industrial scale.
- endotoxin derivatives mention may in particular be made of detoxified endotoxins, endotoxin fragments, endotoxins conjugated with other molecules, in particular with proteins.
- endotoxins to prepare vaccine compositions is cited in particular in EP-976402.
- the invention therefore also relates to a process for the preparation of a composition comprising one or more endotoxins or derivatives of endotoxins, such as in particular endotoxin fragments, detoxified endotoxins, intended for human or animal administration, characterized in that it includes a step of isolating endotoxins as described above.
- the isolated endotoxins are incorporated into an appropriate vehicle, in particular a pharmaceutically acceptable vehicle. They can also be packaged directly for an extemporaneous preparation of the composition intended for human or animal administration.
- lyophilized cells or the equivalent of wet bacterial pellet
- the mixture is centrifuged at 2000 g for 15 minutes at room temperature.
- the clarified supernatant, containing the endotoxin is filtered on sandpaper (Whatman GF / D), diluted with three volumes of distilled water and dialysis. A second extraction of the pellet can be carried out if necessary.
- the dialysis retentate is filtered on sandpaper under the same conditions as above, then lyophilized, and it is extracted with a mixture of chloroform and methanol (1: 2) to remove any phospholipid contaminants.
- the residue from the extraction is then lyophilized.
- the two filtration steps can be carried out on sintered glass (16-40 ⁇ m) covered with sandpaper and a partial vacuum can be applied to speed up the process subject to quality control of the filtrate on TLC.
- the yield is 2 to 10%> depending on the bacteria.
- the extraction is carried out in 24 hours. This duration can be further reduced to a few hours by filtration dialysis methods, applicable on an industrial scale.
- the bacteria When the bacteria contain capsular polysaccharides in large quantities, it may be advantageous to eliminate them by washing the cells before carrying out the extraction.
- FIG. 1 represents a comparative thin layer chromatography of the endotoxins isolated by these two methods.
- SDS-PAGE gel, TLC and mass spectrometry made it possible to verify the effectiveness of the method and the integrity of the endotoxins.
