Definitions
- the invention relates to conjugates for distinguishing diseased tissue from healthy tissue, methods for producing such conjugates and their
- the present invention is therefore based on the object of providing a means with which pathological tissue can be distinguished from healthy tissue and pathological tissue can be treated at the same time.
- polycyclic, planar, aromatic compounds can be coupled by means of a bifunctional acid chloride to a protein which is not considered to be foreign to the body, in particular native, without denaturing the protein. It has also been found that such a conjugate can be used for the detection and therapy of diseased tissues.
- the invention further relates to the use of this conjugate for the detection and / or therapy of tumor cells and inflammatory cells.
- Any polycyclic aromatic planar compounds can be used, provided that they contain a functional group (eg -NH 2 , -SH, -OH) for coupling with a bifunctional acid chloride.
- a functional group eg -NH 2 , -SH, -OH
- flavone dyes such as, for example, morin or quercetin, purpurin, quinalizarin, alizarin, acid black 48, aclarubicin, acridine yellow, alizarin complexon, di- and tri-hydroxyanotrachinones, diaminoanthraquinone, doxorubicin, ethidium bromide, fuchsin, 7-
- the reaction with the protein is carried out using bifunctional acid chlorides, such as Thionyl chloride, bromide or (thio) phosgene, in a polar organic anhydrous solvent.
- bifunctional acid chlorides such as Thionyl chloride, bromide or (thio) phosgene
- DMPH N.N'-dimethylpropylene urea
- DMAA dimethylacetamide
- DMSO dimethyl sulfoxide
- the bifunctional acid chloride is preferably used in a two- to four-fold molar excess. There are no cross-links or denaturing reactions of the protein or other negative changes to the reaction partners. This even applies if a five- or multiple excess of bifunctional acid chloride compared to the agent to be activated is used.
- the protein which is not considered foreign to the body, is preferably native. This preferably has a molecular weight of up to 100,000 daltons, in particular 30,000 to 100,000 daltons. It is preferably albumin or transferrin, in particular native bovine or human serum albumin, with human serum albumin being very preferred.
- the process takes place in such a way that the polycyclic aromatic compound is preferably placed in a polar anhydrous organic solvent at room temperature or slightly higher (up to about 40 ° C.) and the bifunctional acid chloride dissolved in an organic solvent, for example dioxane, is added with stirring . In most cases there is a color change. An aliquot of this solution is added very slowly (corresponding to a 1 to 5 times, preferably 1, 5 to 2 times, molar amount of the albumin presented) to an albumin solution, which preferably contains a small amount of NaHC0 3 , for example ⁇ 50 mg / ml 0.17 M NaHC0 3 . After a reaction time of about 10 to 60 minutes, preferably ⁇ 30 minutes, the non-protein-bound parts of the polycyclic aromatic compound, the solvent and reaction products of the excess acid chloride are separated from the conjugate according to the invention by multiple ultrafiltration.
- an organic solvent for example dioxane
- Tumor cells and inflammatory cells take up large amounts of protein, especially albumin, and break them down to cover the nitrogen and energy requirements.
- Conjugates of protein (especially albumin) and a polycyclic, planar, aromatic compound are built into the diseased tissue, stain it and enable the doctor or surgeon to do so
- conjugates according to the invention Due to the long residence time of the conjugates according to the invention in the circulation (approx. 17-19 days) and their low renal and hepatic clearance, absorption is also possible in the case of protracted pathological processes.
- the conjugates are ubiquitous, i.e. also e.g. in the extravascular space, in the lymph channels and lymph nodes, and are therefore suitable for the detection and treatment of latent disease processes.
- albumin or its native conjugates are not absorbed by normal tissues, which means that they experience no or only minimal damage.
- FIG. 5 where the time-dependent whole body distribution and tumor accumulation of a conjugate according to the invention is shown.
- any pathological or diseased tissue of any location can be detected and treated, e.g. Tissue neoplasia, malignant tumors, inflammatory processes, e.g. triggered by bacteria, viruses, fungi or cell parasites.
- pathogens are e.g. Streptococcus, HPV, wart virus, herpes virus, pathogen of malaria or sleeping sickness.
- Polycyclic compounds with a preferably chemotherapeutic effect act regardless of the location of the process. This is a great advantage over compounds whose fluorescence is for diagnostic or phototherapeutic
- conjugates according to the invention do not have an immunogenic effect, ie do not trigger antibody production when administered to the human or animal organism.
- the invention is explained in more detail with reference to the figures:
