Definitions

  • the object of the present invention is therefore to provide a method with which complex compounds can be covalently and irreversibly linked to each other and which can also be used for the construction of substance libraries.
  • R H, alkyl, aryl, heterocycle, which in turn may be optionally substituted with alkyl, OH, SH, halogen, aryl, heterocycle, nitro, carboxyamido, or amine Group.
  • the diene component may, however, also carry amino acid, peptide, saccharide, lipid or oligonucleotide or nucleic acid substituents at one or more positions.
  • the diene component can also be coupled to all types of pharmaceutical actives, labels, dyes, complexes (e.g., carborane, ferrocene), quantum dots, chelating agents, diagnostics or therapeutics, and combinations thereof
  • Tetrazines have a high reactivity as dienes in the inverse DAR.
  • the model compound for many studies is the readily available tetrazinodicarboxylic acid dimethyl ester.
  • changes to this compound such as nucleophilic substitutions, but lead to decomposition.
  • many reactions of the ester function with nucleophiles can be easily and quickly performed on the dihydro precursor. Since the rate of the first nucleophilic substitution with amines is usually greater than the rate of the second nucleophilic substitution, monosubstituted amides are easily prepared, thus opening the way to the preparation of unsymmetrical diamides.
  • the peptides can also be labeled either on the solid phase or after cleavage by the DARinv with dyes or biotin.
  • the aim is to produce platinum complexes in which either the diamine ligand or the dicarboxylic acids used as the leaving group are formed as dienophile or as diene.
  • the structures listed below are intended to illustrate this concept. This makes it possible to selectively the respective part of the Complex by the DARinv targeted change. This makes possible the construction of libraries of the original complex.
  • the change in the leaving group, in this case the dicarboxylic acid, by the DARinv appears to be particularly interesting since this leaving group is split off during the intracellular activation of the Pt complexes and thus also the respective part attached by the DARinv.
  • platinum complex of 1,2,3-triaminopropane shown is known, it can be bound to the tetrazine via its free amino group, thus providing another building block for the incorporation of Pt complexes into proteins, saccharides and other biomolecules and therapeutics.
  • Positron emission tomography is a radioactive, non-invasive, but very sensitive diagnostic method.
  • the most commonly used positron emitter is F18, which decays into the element oxygen with a half-life of 18 min, releasing a positron. Because of the low Half life requires the preparation of appropriate F18-labeled compound in particular synthetic methods. They have to run fast and necessary cleaning procedures have to be easy.
  • the most commonly used compound today is 2-fluoro18-2-deoxy-glucose.
  • the ligation reaction based on the DARinv can be used very well for labeling peptides, oligonucleotides and saccharides with F18.
  • Nucleophilic substitution reactions on aromatics are facilitated as the number of nitrogen atoms in the ring increases, such as in the series benzene, pyridine, pyrimidine and triazine.
  • a thiomethyl radical can easily be replaced by a number of nucleophiles, including halogens.
  • triazines react as dienes in the DARinv
  • the prior introduction of F18 into such a triazine offers the elegant possibility to label the abovementioned biopolymers with F18 with the aid of the DARinv and thus make them accessible for detection by PET.
  • the classical way of nucleophilic substitution on tosylates with fluoride can be labeled (see below).
  • the introduction of trifluoroacetyl groups labeled F18 via the amine function of the described tetrazines and triazines can be used here.
  • the tetrazine can be trifluoacetylated in pyridine and directly in the Solution that DARinv perform.
  • the DARinv allows very short reaction times and usually proceeds without the formation of by-products.
  • the dihydro-tetrazine dicarboxylic acid ester can be reacted with amines at RT with primary amines.
  • This high reactivity can be used to build up reactive solid phases.
  • the reaction sequences shown here can be carried out in yields between 70 and 90%.
  • solid phases are available which carry either a diene or a dienophile for the DARinv.
  • the reactivity in the DARinv is so high that the dienophile-bearing solid phase can be literally titrated with a tetrazine.
  • the resulting applications range from the chip technology for oligonucleotides, proteins or saccharides to catalytic surfaces and solid phase reagents.
  • any substituents can be introduced into oligonucleotides obtained by synthesis.
  • the required amidites have been prepared by and. In this way, a multiple mark is possible.
  • Quantum dots are nanoparticles made up of compounds such as CdS or CdSe and have special optical properties. Upon excitation with lasers they fluoresce very strongly depending on their size and therefore find more and more use in the diagnostic field, especially as they make the detection of single molecules possible. The prerequisite for this, however, is their doping with functional groups which proceeds via SH groups and permits a subsequent interaction with the molecules to be detected. Due to their special properties, gold nanoparticles are used for electron microscopic investigations of biomolecules. Again, the anchoring of molecules on the surface via SH groups accomplished. Again, the new ligation technique can be used by DARinv.
  • SH-group-containing triazines and tetrazines were prepared, wherein first the disulfides were prepared and from this by reduction with dithiothreitol the mercapto compound.
  • SH-containing dienophiles of the norbornene type can also be prepared. The disulfides themselves were also anchored to gold surfaces.
  • both the dienes tetrazines, triazines and diazines
  • dienophiles can be deposited via the disulfide group as to the surface of the quantum dots or other metals and are therefore accessible to the DARinv.
  • antibodies, peptides, saccharides or therapeutics can be anchored to the surface of the quantum dots for diagnostic or therapeutic purposes.
  • the synthesis of complex saccharide structures requires a sophisticated protecting group strategy.
  • the reducing end is often protected by an allyl group or a pentenoyl group.
  • isolated oligosaccharides can be easily provided with an allyl group or pentenoyl group at the reducing end.
  • the conditions for anchoring these oligosaccharides to a solid phase or surface are given by the DARinv.
  • the furan saccharide mimetics described in DE-A-100 41 221.1 can likewise be anchored either to biomolecules or surfaces with the aid of this DARinv technology.
  • Prerequisite is the introduction of an allyl ether group or the use of linker molecules as described above.
  • saccharide mimetics are also suitable as inverse dienophiles in the DARinv and can thus be introduced into any biomolecules.
  • vitamin A, vitamin C, curcumin or other therapeutic agents can be coupled to proteins or surfaces and released there by hydrolysis or enzymatic cleavage.
  • Another example of this application is the temozolomide used to treat brain tumors, which can be coupled via its acid function either to a tetrazine or to a dienohile.
  • the DARinv then the coupling to peptides is possible.
  • liposomes containing double bonds that are active in the DARinv can be easily modified with this technology, thereby improving targeting or modification
  • Both systems are suitable for the sequential coupling of molecules which carry either the same dienophile as L 1820 or different dienophiles such as L 1825.
  • This type of compound is also suitable for anchoring to a solid phase by reaction with the carbonyl or the carbonyl group
  • the ketone dicyclopentadienone is an orthogonal dienophile that is accessible to both normal DAR and DARinv. By reaction with butadiene, it can also be converted into a double inverse dienophile (s. In addition to these linkers from dienophiles, linkers from dienes that allow DAR and DARinv at the same time are also available.
  • linkers from dienophiles linkers from dienes that allow DAR and DARinv at the same time are also available.
