Definitions
- the present invention relates to a trifunctional pseudopeptide reagent, for its various uses, in particular for the preparation of luminescent reagents or bioconjugates, optionally luminescent, the use of these reagents and bioconjugates for the functionalization of solid supports, as well as for the use of the solid supports thus functionalized for the detection of molecules of interest.
- bioconjugates derived from biopolymers involve being able to covalently (reversibly or non-reversibly) attaching these bioconjugates to a second molecular architecture (biopolymer, solid support,. ..) and to detect and / or quantify them accurately (optical detection, radioactive, ).
- a second molecular architecture biopolymer, solid support,. ..
- it is essential to have tools for effectively combining a biopolymer with other (macro) molecules without significantly altering the properties of each of the partners involved in the resulting and targeted molecular architecture.
- bifunctional cross-linking reagents For this purpose, many small bifunctional molecules (better known as "bifunctional cross-linking reagents") have been developed. A large number are marketed by Pierce. However, it is interesting to note that several academic groups continue to work on the development of new bifunctional reagents that are increasingly sophisticated and allow the development of ever more complex bioconjugates.
- the sulfo-SBED is not entirely satisfactory inasmuch as it is not possible to modulate the hydrophobic / hydrophilic nature and especially the third functional unit (ie biotin) allows only strong interaction (quasi -covalent) with partners previously conjugated to avidin (glycoprotein) or streptavidin, which greatly limits its use.
- trifunctional reagents for preparing bioconjugates consisting of a trifunctional central unit selected from triaminobenzene, tricarboxybenzene, dicarboxyaniline and diaminobenzoic acid, on which three affinity ligands, a biomolecule-reactive group and an effector agent are attached via three distinct linker arms.
- This reagent has the disadvantage of having a trifunctional central unit consisting of at least two identical chemical functions (ie, carboxylic acid or amine functions) which restricts the choice of the complementary functions carried by the connecting arms which may have a limiting effect.
- trifunctional reagents comprising three distinct functional poles, namely a luminescent group (L), a molecule (B) selected from the analyte to be detected, an analogue or a fragment thereof and finally a function ensuring the attachment of said trifunctional reagent to the surface of a solid support
- L luminescent group
- B molecule
- the present invention therefore firstly relates to a trifunctional pseudopeptide reagent, characterized in that it comprises at least the following three reactive structural units A, B and C:
- a unit A consisting of a hydrophilic chain of pseudopoly (ethylene glycol) (pseudo-PEG chain) interrupted by at least one amide function and having two ends E1 and E2, said E1 end being free and having a pattern terminal selected from amino group (-NH 2 ), activated carbamates and activated esters, and said E2 end having a terminal carbon atom carrying a carbonyl function, said carbon atom being engaged in an amide function (-C (O) -NH-) formed with the nitrogen atom of an ⁇ -amine function carried by the unit B;
- a unit B consisting of an amino acid chosen from ⁇ -amino acids of the L, D series and their racemic mixtures, said amino acid having on its side chain at least one oxyamine function protected by a protecting group or at least one minus a masked aldehyde function; and (c) a unit C consisting of an amino acid selected from ⁇ -amino acids of the L, D series and their racemic mixtures, said amino acid having on its side chain at least one thiol, maleimide, iodoacetyl, azide unit, true alkyne, phosphane or cyclooctyne; said units B and C being linked to one another via an amide function formed between the carbon atom carrying the carbonyl function of the ⁇ -amino acid constituting the unit B and the nitrogen atom of the ⁇ -amine function of the ⁇ -amino acid constituting the unit C.
- the main originality of these structures lies in the combination of amino acids (natural or modified) protected on their side chains by selected protective groups, and a functionalized pseudo-PEG chain whose length is easily adjustable. Even if the presence of several chemical functions (protected or not) necessarily entails problems during the preparation of these reagents (incompatibilities between functions, degradation and / or premature deprotection of certain protective groups, ...), the structure segmented into three Separate structural units (prepared independently of each other and then coupled together in the final steps of developing the trifunctional reagent) allows for a highly convergent synthesis strategy that minimizes the simultaneous presence of incompatible chemical motifs between them. Furthermore, a large structural diversity (modulation of geometry, length, physicochemical properties and solubility in particular, etc.) is accessible by modifying only one of the three structural units of the trifunctional reagent.
- the term "pseudo" -PEG string a string having great similarities of structure with the PEG chain: but which differs by the presence of one or more functional groups (ester, amide, carbamate, urea, ...) within it.

Moreover, the primary amine function which may alternatively be present at the free E-terminus of the pseudo-PEG chain constituting unit A is reactive with respect to compounds having a complementary unit such as a carbamate or an activated ester .
- This end E1 allows in particular the fixation of biological macromolecules which comprise, naturally or not, said complementary reactive functions (antibodies, nucleic acids or analogs, polysaccharides, proteins, peptides, radionuclides, toxins, enzyme inhibitors, haptens, etc.). .).
- unit B after possible activation, that is to say after deprotection in the case of the oxyamine function or after unmasking in the case of the aldehyde function, under mild conditions compatible with the stability of the various partners involved, is reactive vis-à-vis compounds or materials having one or more carbonyl groups (aldehyde, ...) or alternatively amine.
