Definitions
- the invention relates to novel compounds capable of modulating the activity and stimulating the production of catalytic antibodies.
- the invention relates in particular to a compound capable of increasing the activity of a catalytic antibody characterized in that it has a specific affinity for the catalytic site of said antibody, and in that it is not immunogenic.
- Such compounds are useful in particular for the therapeutic treatment or prevention of a pathology linked to an enzymatic deficiency, to stimulate in vivo the hydrolysis of xenobiotics, drugs, medicaments or any other molecule potentially toxic for the organism or again to prevent or prevent allergic reactions.
- Antibodies and enzymes have in common the property of specifically recognizing molecules. With the exception of pathological cases, the antibody recognizes an antigen or a molecule which is foreign to the organism producing the antibody. The binding of the antibody to the antigen generally leads to the neutralization of the foreign molecule in the organism. Enzymes are biological catalysts that bind to a molecule so that the activation energy of a reaction involving the molecule is lowered, thereby increasing the speed of the reaction.
- antibodies with catalytic activity could be isolated from the serum of patients suffering from different pathologies.
- the first demonstrations were carried out by purifying the antibodies from human sera. These “natural” catalytic antibodies in particular have DNAse or protease activities.
- catalytic antibodies exhibiting protease activity against the intestinal vasoactive peptide (VIP) were thus isolated from the serum of patients suffering from asthma. These same antibodies were obtained by the immunization of mice with the same immunogenic peptide (Paul et al., J Neuroimmunol (1989) 23: 133-142).
- catalytic antibodies are multiple.
- such catalytic antibodies would be useful for the catalysis of chemical reactions which are not carried out by natural enzymes, in particular for acting in vivo on the metabolism (medical application) or carrying out specific chemical reactions (industrial application).
- One of the applications which has been developed relates to the use of the hydrolytic properties of catalytic antibodies to activate non-toxic compounds into cytotoxic compounds (Zeneca Ltd, 1998, US 5807688). By targeting this activity at the level of target cells, molecules whose cytotoxicity is masked by a chemical group could be activated on contact with tumor cells for anti-cancer treatments (ADAPT method, Antibody-directed Abzyme Prodrug Therapy). Another example concerns the ability of certain antibodies to hydrolyze cocaine. The development of an antibody with these properties could allow its use in the treatment of overdoses and cocaine addiction.
- the patent describes a method of inducing the stimulation of catalytic antibody using the immunization of a mammal with a hapten, analog of transition states (Barber et al., 2000, US 6,017,541).
- a third example is developed by Advanced Biotech, which produces catalytic antibodies for the treatment of infections with gram-negative bacteria by targeting endotoxin (Genetic Engineering News (1999) vol. 19 no. 20 page 15).
- the invention results from the discovery that it is possible to modulate in vivo the activity of a catalytic antibody using a non-immunogenic compound and having a specific affinity for the catalytic site of said antibody.
- Such compounds have a direct effect on catalytic activity by inducing conformational change of antibodies already produced.
- the inventors have found that, in spite of the non-immunogenic nature of these compounds, they could indirectly increase the production of catalytic antibodies, by shifting the balance of the immune system towards the production of antibodies. with increased catalytic activity, this displacement being induced by the conformational change of the pre-existing antibodies.
- the invention relates to a compound capable of modulating the activity of a catalytic antibody, said compound being characterized in that it has a specific affinity for the catalytic site of said antibody, and in that it is not not immunogenic.
- It also relates to a method of modulating the activity of a catalytic antibody comprising bringing said antibody into contact with a non-immunogenic compound and having a specific affinity for the catalytic site of said antibody.
- a catalytic antibody is an antibody capable of recognizing in a specific but not exclusive manner, two types of molecules: the antigen or immunogen, that is to say a molecule capable of inducing a direct immune response by the activation of B lymphocytes or T specific according to the nature of the antigen, and, the substrate, which specifically recognizes the catalytic site of the antibody and, as its name indicates, is the substrate for the chemical reaction catalyzed by the catalytic antibody.
- non-immunogenic compound a compound incapable of directly activating specific B or T lymphocytes
- the catalytic antibodies can be presented in two isoforms: an isoform known as “inactive” or “slightly active” (hereinafter called Ab), and an isoform known as “active” (hereinafter called Ab *).
- the active isoform (Ab *) has a catalytic activity (hereinafter called kcat *) greater than that of the non-active isoform (hereinafter called kcat).
- kcat * catalytic activity
- the change in conformation induced by the compound according to the invention thus leads to the in vivo modulation of the catalytic activity of the antibody which goes from a kcat value to a value kcat *, the value kcat * being different from the value k ⁇ t.
- a modulation of the catalytic activity can thus be obtained on catalytic antibodies present in the serum of patients by the injection in the form of a well of the compounds according to the invention, according to methods analogous to those implemented for a vaccine.

- the enzymatic activities deficient or reduced following a pathology or a therapeutic treatment can be for example activities of the hydrolase type and in particular peptidase, protease activities, oxidoreductase type activities (for example dehydrogenase, oxidase or oxygenase), isomerase activities, lyase activities and in particular decarboxylase, transferase activities and in particular kinase activities, or else ligase activities.
- pathologies include:
- leukemia which is the consequence of a deficit in keto-acid decarboxylase
- Lesch-Nyhan syndrome which is the consequence of a deficit in hypoxanthine guanine phosphorisbosyl-transferase

- a compound according to the invention is chosen from a viral, bacterial or parasitic peptide.
- Such compounds are thus capable of stimulating catalytic production degrading the bacterial or parasitic viral proteins and allow thus to fight against the corresponding viral, bacterial or parasitic infections.
- peptides are non-immunogenic peptides derived from surface epitopes or virulence proteins from pathogenic organisms such as HIV, HSV or HBV viruses, from pathogenic bacteria such as Legionella, Listeria, Staphylococcus, or from parasites such as P. faciparum, Echinococcus, Leishmania or Trypa ⁇ osoma.
- an example of such a compound according to the invention is a compound characterized in that it comprises a non-immunogenic peptide derived from an epitope of a Herpes virus.
- a compound according to the invention is a recalcitrant and potentially toxic xenobiotic or one of its fragments.
- xenobiotic recalcitrant means any molecule foreign to the organism capable of accumulating in the tissues or the interior environment of a man or an animal. Some of these molecules, and in particular pesticides (organophosphorus compounds), dioxin or organochlorines (PCB, DDT 7), are potentially toxic for the organism, in particular in the long term.

In the case of non-specific type recognition, that is to say by the Fc regions of the antibodies, the catalytic activity can be targeted on cells of the cellular type immune system, this then adding to the action on the humoral system (synthesis of antibodies sought by B lymphocytes).
- the compounds according to the invention make it possible to target the catalytic activity on a chosen target, said target comprising said epitope.
- targets are antibodies with double specificity both for a specific epitope and for the enzyme substrate.
- the compounds according to the invention make it possible to target a catalytic activity to effectors of the immune and / or inflammatory system.
- the invention finally relates to a method for selecting a compound according to the invention comprising the selection and isolation of a natural or induced catalytic antibody by repeated injection of an immunogenic molecule, characterized in that it further comprises the following steps: a) synthesis and / or extraction of compounds derived from an immunogenic molecule recognized by the isolated catalytic antibody; b) if necessary, a first screening using a biological and / or biochemical test of the compounds interacting with the catalytic site of said catalytic antibody, c) the selection of non-immunogenic compounds having a specific affinity for the catalytic site of the antibody among the compounds synthesized or extracted in step a) or selected in step b), using a test allowing the measurement of said affinity.
- step (a) of the process of the invention it is a question of obtaining compounds derived from an immunogenic molecule recognized by the catalytic antibody selected and isolated beforehand.
- the compounds can be synthesized in particular by combinatorial chemistry, by biosynthesis or by bioconversion.
- the chemical structure of the compounds synthesized in (a) can also be predicted using bioinformatic methods for predicting chemical structure.
- the compounds are derived from an immunogenic peptide and are synthesized by mutagenesis of a DNA encoding said immunogenic peptide and by the expression of the mutated DNA in a host cell according to biological methods molecular known to those skilled in the art such as those described by Sambrook et al. (Molecular Cloning: a laboratory manual, 3 rd Ed. Cold Spring Harbor, Laboratory press, New York, 2001).
- the method may include a first screening step (step (b) of the method) using a biological test and / or biochemical of compounds interacting with the catalytic site of said antibody.
- This step consists, after having generated a large number of compounds derived from the immunogenic compound, to first select the compounds which have retained the property of binding to the catalytic antibody in order to reduce the number of compounds to be screened in step (c). Any test making it possible to identify, among a set of compounds, the compound or compounds interacting specifically with a given catalytic antibody can be used in the method of the invention.
- the compounds synthesized or extracted in step (b) are peptides and are selected using a biochemical screening of the catELISA test type (Tawfik et al. 1993, supra). ), a screening on a protein chip or a screening by measuring the resonant plasmonic surface.
- a protein chip consists of a support on which are fixed at determined positions the different peptides to be screened.
- the labeling of the catalytic antibody and the contact with the protein chip under conditions allowing protein-protein interactions allow the selection of the peptides interacting specifically with the catalytic antibody.
- any biochemical method making it possible to test the interaction of a peptide with an antibody and in particular the methods derived from the Western blot, can be used in the method of the invention to carry out the biochemical screening of the compounds interacting with the antibody.
- the peptide compounds are selected by the phage display technique or by the double-hybrid technique. These methods are well known to those skilled in the art and are described in Sambrook et al. (2001, supra).
- the compounds according to the invention are then selected in step (c) of the process, using a test allowing the measurement of the affinity for the catalytic site of the antibody.
- a compound according to the invention can be selected by measuring the speed of the reaction catalyzed by the catalytic antibody in the presence of either the test compound or the reference immunogenic compound.
- the speed of the reaction catalyzed by the antibody, measured in the presence of the test compound is significantly higher than that measured in the presence of the reference immunogenic compound, the test compound is selected.
- any type of test making it possible to measure the affinity constant of the compound-antibody complexes can be used to select the non-immunogenic compounds according to the invention.
- Another aspect of the invention relates to new methods of therapeutic treatment.
- the invention relates to a method:
- the methods comprise the administration to an organism of a pharmaceutical composition comprising, as active principle, a compound according to the invention, alone or in combination with another pharmacologically active substance capable of increasing in vivo. activity of a catalytic antibody, in combination with an appropriate pharmaceutical vehicle.
- the modes of administration, the composition of the vehicle and the dosage of the compounds administered for the treatment will be chosen according to the therapeutic or preventive effect sought.
- the forms of administration can be local or systemic and in particular oral, sublingual, intravenous, nasal, aerosol, intramuscular, subcutaneous or food.
- treatment methods of the invention will in general be similar to vaccine methods, the person skilled in the art may refer in particular to vehicles conventionally used in this field.
- Figure 1 illustrates the induced fit mechanism allowing a non-immunogenic compound to shift the balance of conformational states of a catalytic antibody from inactive or inactive catalytic forms to active isomeric forms .
- the shift in equilibrium leads in vivo to an increase in the catalytic activity of the catalytic antibody and indirectly to a stimulation of its production.
- EXAMPLE 1 Compound capable of increasing the catalytic activity of the secreted IgAs directed against epitopes of the Herpes virus to fight against infections with the Herpes virus.
- IgA secreted IgA are the main effectors of the mucosal immune system. They are notably involved in the recognition of bacterial, viral or protozoan antigens. It has been shown in particular that IgA extracted from healthy breast milk can possess catalytic activities of protein kinase, DNase or RNase type (Buneva VN et al. (1998) Appl. Biochem. Biotechnol. 75: 63-76, Nevinsky GA et al. (1998) Appl. Biochem. Biotechnol. 75: 77-91).
- the production of a catalytic antibody directed against epitopes of the Herpes simplex virus type 1 virus could be stimulated by the cutaneous application of non-immunogenic peptides in the form of patches.
- the non-immunogenic peptides chosen represent the specific sequences of the known epitopes of I ⁇ SV1.
- a similar approach can be implemented to stimulate the production of catalytic antibodies hydrolyzing peptides from HSV2, responsible for genital herpes, or from herpes Zoster, responsible for shingles.
- EXAMPLE 2 Compound capable of increasing the catalytic activity of an antibody hydrolyzing certain peptide sequences of TNF ⁇ for the treatment of rheumatoid arthritis.
- TNF ⁇ tumor necrosis factor
- TNF ⁇ The inflammatory action of TNF ⁇ is linked to its attachment to two cellular receptors, p55 and p75. This fixation involves TNF ⁇ loops formed by residues 29-34, 84-91 and 143-148.
- Non-immunogenic peptides having a specific affinity with a catalytic antibody capable of hydrolyzing TNF ⁇ are selected from peptides containing the sequences LNRRA (29-33), IASVY (83-87) and LFA (143-145).
- LNRRA 29-33
- IASVY 83-87
- LFA 143-145
- EXAMPLE 3 Compound capable of increasing the catalytic activity of an antibody hydrolyzing cocaine to treat drug addiction phenomena.
- Drug use in a subject causes addiction.
- the amount of drug circulating in the blood after administration is directly related to the amazing effect and the addiction that follows.
- Immunization of a subject using immunogenic peptides directly stimulating the production of catalytic antibodies hydrolyzing cocaine makes it possible to reduce, even eliminate, the quantity of circulating cocaine.
- low concentrations of codeine, a non-immunogenic compound similar to cocaine could be injected repeatedly, intravenously.
- EXAMPLE 4 Compound capable of increasing the catalytic activity of an antibody with ⁇ -lactamase activity.
- This antibody allows the production of a second generation of Ab2 antibodies, anti-idiotypic, and carrying an activity close to that of ⁇ -lactamase.
- the lethality linked to the repeated injection of penicillin should be reduced, by stimulating the production of anti-idiotypic antibodies with ⁇ -lactamase activity by the administration of non-immunogenic peptides mimicking the paratope of the antibody induced in the presence of active site of ⁇ -lactamase.
- EXAMPLE 5 Compound capable of increasing the catalytic activity of antibodies hydrolyzing an allergen to reduce or prevent an allergic reaction.
- Specific desensitization induces both an increase in serum and secretory blocking antibodies, a decrease in production specific IgE and modification of the response of mast cells, basophils and lymphocytes.
- the administration to a sensitive subject of an allergen of a nonimmunogenic molecule derived from the allergen should make it possible to modify the immunological response towards the increase in the production of catalytic antibodies directed against this allergen, an indirect increase in the production of serum and secretory blocking antibodies and. the decrease in the production of specific IgE, taking into account the hydrolysis of the allergen. All of these responses help reduce or prevent the allergic reaction.
- Non-immunogenic peptides to prevent or reduce allergies to anti-infective drugs.
- Antibiotics are the molecules most often implicated in reactions of allergies to anti-infective drugs (50% of cases). We know in particular that allergenicity is in the vast majority of cases carried by the ⁇ -lactam cycle. By being cleaved during metabolism, the ⁇ -lactam cycle gives the penicilloyl hapten which is capable of inducing the production of IgE.
- Non-immunogenic peptides that inhibit ⁇ -lactamase activity injected in oral form, to induce the production of non-IgE antibodies capable of hydrolyzing antibiotics with a ⁇ -lactam nucleus, thereby preventing the production of IgE antibodies.
- a peanut allergy is affecting an increasing number of people.
- the severity of the shocks to which it gives rise as well as its frequency are increasing.
- a 17 kD protein, Ara h II has been identified as a major and characterized allergen. Sequence comparisons made it possible to identify sequence homologies with proteins of different foods from the legume family that could cause cross-sensitization.
