Definitions
- the invention relates to the subject characterized in the claims, that is, the use of conjugates of residues and active groups binding to endothelin receptors for the therapy of diseases.
- the invention relates in particular to the use of conjugates from endothelin derivatives, partial sequences of endothelin, endothelin analogs or endothelin antagonists and an active group for the therapy of vascular diseases.
- Another aspect of the invention relates to new endothelin conjugates, agents containing these compounds and methods for their preparation.
- Cardiovascular diseases are one of the most widespread diseases in the industrialized countries. They are one of the most common causes of death. In the vast majority of cases, cardiovascular diseases are caused by atherosclerosis. This is an inflammatory, fibroproliferative disease that is responsible for 50% of all deaths in the United States, Europe and Japan (Ross 1993, Nature 362: 801-809). With its peripheral characteristics, it threatens the preservation of the
- Atherosclerosis is currently treated in different ways. In addition to the conservative measures (e.g. lowering the rate of the blood pressure).
- Thromboses impaired (Sigwart et al. 1987, N. Engl. J. Med. 316: 701-706). Long-term success is endangered by the recurrence of restrictions (restenoses).
- the CAVEAT study showed that the restenosis rate of 1012 patients six months after the intervention was 50% in coronary atherectomy and even 57% in coronary angioplasty (Topol et al. 1993, N. Engl. J. Med. 329: 221-227). Furthermore, abrupt vascular occlusion occurred in 7% of atherectomy patients and in 3% of angioplasty patients. Nicolini and Pepine (1992, Endovascular Surgery 72: 919-940) report a restenosis rate between 35 and 40% and an acute closure rate of 4% after angioplasty.
- An alternative method of treating atherosclerotic diseases uses ionizing radiation. It is known, for example, that ionizing radiation inhibits the proliferation of cells. A variety of neoplastic and non-neoplastic diseases have been treated in this way (Fletcher, Textbook of Radiotherapy, Philadelphia, P.A: Lea and Febiger, 1980, Hall, Radiobiology for the Radiologist, Philadelphia, P.A: Lippincott, 1988).
- neointimal hyperplasia a number of other therapeutic strategies for inhibiting neointimal hyperplasia (restenosis) are also used. These include classic drugs for restenosis suppression such as antithrombotics, platelet aggregation inhibitors, calcium antagonists, anti-inflammatory and anti-proliferative substances, but also gene therapy approaches. It is possible to inhibit growth stimulators, for example by means of antisense oligonucleotides, or to amplify inhibiting factors by means of expression vector plasmids and virus-mediated gene integration. Aptamer oligonucleotides can also be used to inhibit a wide variety of receptor-mediated processes that play a crucial role in restenosis.
- PTK inhibition is not free of side effects, since PTKs are also responsible for normal proliferation and metabolic processes (eg insulin receptor or NGF receptor) (Levitzki 1992, FASEB 6, 3275-3282).
- Another unsolved problem is the insufficient length of stay of the PTK blockers and their lack of selectivity.
- all PTK blockers must be able to cross the cell membrane in order to be effective.
- cytostatics such as Cis-diaminedichloroplatin (cisplatin) used for the therapy of neoplastic diseases (Rozencweig et al., 1977. Ann. Intern. Med., 86, 803-812).
- cisplatin proves to be a very effective therapeutic agent for the application mentioned, its broad application is prohibited, since the therapeutic window of this substance is very limited due to the various, in some cases drastic, systemic side effects. Above all, the nephrotoxic effect of renally eliminated cisplatin is responsible for the limited clinical use of this substance (Dentino et al. 1987, Cancer 41, 1274-1281, Groth et al. 1986, Cancer Chemofher. Pharmacol. 17, 191-196).
- conjugates from endothelins and at least one active group are outstandingly suitable for therapy, in particular for the therapy of vascular diseases.
- endothelin conjugate also means conjugates of endothelin derivatives, partial sequences of endothelin, endothelin analogs or endothelium-antagonists.
- the invention thus relates to the use of endothelin conjugates for the therapeutic treatment of vascular diseases.
- Another aspect of the invention relates to new conjugates from endothelins, endothelin derivatives, partial sequences of endothelins, endothelin analogs or endothelin antagonists and at least one active group, processes for their preparation, agents containing these conjugates and their use in diagnostics and therapy. It has been found that conjugates of endothelins, endothelin derivatives, partial sequences of endothelin, endothelin analogs or endothelin antagonists and an active group accumulate in cells and tissues in which endothelin receptors are increasingly expressed. These receptors are particularly found in atherosclerotic deposits (plaques).
- the endotheline despite being coupled to an active group, maintains its high specificity towards these receptors, so that a therapeutically effective enrichment of the active group at the target site can be achieved even at low doses.
- the residence time of the conjugates is also long enough to achieve the desired therapeutic effect.
- the concentration in other tissues does not reach a toxic range at this dosage, in particular because the conjugates not containing the active muscle groups that bind to the smooth muscle cells are quickly eliminated from the body and the burden on the patient caused by the unbound conjugate is minimal. The systemic side effects observed are therefore minor.
- conjugates according to the invention are also absorbed into the cell as a substance-receptor complex after binding to the receptors. So it is not only possible to target the target groups
- endotheline endotheline, endothelin derivatives, partial sequences of endothelin, endothelin analogs or endothelin antagonists:
- Antibodies, antibody fragments, peptides, carbohydrates, oligonucleotides, hormones or chemotherapeutic agents come into consideration as active groups.
- the active groups can also be radioactive metal isotopes and their metal complexes as well as radioactive isotopes of various non-metals, the latter being bound to the endothelin either directly or via a suitable residue.
- Conjugates with one or more, preferably 1 to 10, active groups or active substance molecules can be used according to the invention.
- chemotherapeutics include vinblastine, doxorubicin, bleomycin, methotrexate, 5-fluorouracil, 6-thioguanine, cytarabine, cyclophosphoamide and cisplatin, as well as other conventional chemotherapeutics (see, for example, Cancer: Principles and Practice of Oncology. 2nd ed., VT De Vita, Jr., S.
