Beschreibung der Erfindung:Description of the invention:
Für die nächsten Jahre wird ein dramatischer Anstieg der Tumorerkrankungen und der Tumor bedingten Todesfälle weltweit erwartet. In 2001 waren weltweit etwa 10 Mio Menschen an Krebs erkrankt und über 6 Mio Menschen sind an dieser Erkrankung gestorben. Die Entwicklung von Tumoren ist eine fundamentale Erkrankung höherer Organismen im Pflanzen-, im Tierreich und beim Menschen. Das allgemein anerkannte Mehrschrittmodell der Krebsentstehung geht davon aus, daß durch Anhäufung von mehreren Mutationen in einer einzelnen Zelle diese so in ihrem Proliferations- und Differenzierungsverhalten geändert wird, daß letztendlich über benigne Zwischenstufen ein maligner Zustand mit Metastasierung erreicht wird. Hinter dem Begriff Krebs oder Tumor verbirgt sich ein Krankheitsbild mit mehr als 200 verschiedenen Einzelerkrankungen. Tumorerkrankungen können gutartig oder bösartig verlaufen. Die wichtigsten Tumoren sind die der Lunge, der Brust, des Magens, des Gebärmutterhalses, der Prostata, des Kopfes und Halses, des Dick- und Enddarmes, der Leber und des Blutsystems. Hinsichtlich Verlauf, Prognose und Therapieverhalten gibt es große Unterschiede. Mehr als 90% der erkannten Fälle betreffen solide Tumoren, die insbesondere in fortgeschrittenem Stadium bzw. bei Metastasierung schwer oder nicht therapierbar sind. Die drei Säulen der Krebsbekämpfung sind nach wie vor operative Entfernung, Bestrahlung und Chemotherapie. Trotz großer Fortschritte ist es bisher nicht gelungen, Medikamente zu entwickeln, die bei den weitverbreiteten soliden Tumoren eine deutliche Verlängerung der Überlebenszeit oder gar komplette Heilung bewirken.A dramatic increase in tumor diseases and tumor-related deaths worldwide is expected over the next few years. In 2001, around 10 million people worldwide had cancer and over 6 million people died from the disease. The development of tumors is a fundamental disease of higher organisms in the plant, animal and human kingdoms. The generally recognized multi-step model of cancer development assumes that the accumulation of several mutations in a single cell changes their proliferation and differentiation behavior in such a way that a malignant state with metastasis is ultimately achieved via benign intermediates. The term cancer or tumor hides a clinical picture with more than 200 different individual diseases. Tumor diseases can be benign or malignant. The main tumors are those of the lungs, breast, stomach, cervix, prostate, head and neck, colon and rectum, liver and blood system. There are big differences in the course, prognosis and therapy behavior. More than 90% of the identified cases relate to solid tumors that are difficult or not treatable, particularly in an advanced stage or with metastasis. The three pillars of cancer control are still surgical removal, radiation, and chemotherapy. Despite great advances, it has so far not been possible to develop drugs which, in the case of the widespread solid tumors, bring about a significant increase in survival time or even complete healing.
Es ist deshalb sinnvoll, neue Arzneimittel zur Bekämpfung der Krebserkrankung zu erfinden. Insbesondere soll die nachteilige Resistenzbildung, wie sie von vielen Antitumormitteln bekannt ist, umgangen werden.Therefore, it makes sense to invent new drugs to fight cancer. In particular, the disadvantageous development of resistance, as is known from many antitumor agents, is to be avoided.
