Definitions

  • the present application relates to novel 3- (fluorovinyl) pyrazole derivatives, processes for their preparation, their use for the treatment and / or prevention of diseases and their use for the preparation of medicaments for the treatment and / or prevention of diseases, in particular for treatment and / or prevention of hyperproliferative and angiogenic disorders, as well as those diseases that arise through metabolic adaptation to hypoxic conditions.
  • Such treatments may be monotherapy or in combination with other medicines or other therapeutic measures.
  • Cancers are the result of uncontrolled cell growth of various tissues. In many cases, the new cells invade existing tissues (invasive growth) or they metastasize to distant organs. Cancers occur in various organs and often have tissue-specific disease courses. Therefore, the term cancer as a generic term describes a large group of defined diseases of various organs, tissues and cell types. In 2002, 4.4 million people worldwide were diagnosed with tumors of the breast, bowel, ovaries, lungs or prostate. For the same year, approximately 2.5 million deaths were reported as a result of these conditions (Globocan 2002 Report). In the US alone, over 1.25 million new cases and more than 500,000 cancer deaths were predicted for 2005. The majority of these new cases involve cancers of the intestine ( ⁇ 100,000), lung ( ⁇ 170,000), breast ( ⁇ 210,000) and prostate (- 230,000). A further 15% increase in cancer over the next 10 years is expected (American Cancer Society, Cancer Facts and Figures 2005).
  • early stage tumors may be removed by surgical and radiotherapeutic measures.
  • metastatic tumors can only be treated palliatively by chemotherapeutic agents.
  • the goal here is to achieve the optimal combination of improving the quality of life and extending the lifetime.
  • Chemotherapies often consist of combinations of cytotoxic drugs. The majority of these substances have a binding mechanism to tubulin, or they are compounds that interact with the formation and processing of nucleic acids. More recently, these include enzyme inhibitors that interfere with epigenetic DNA modification or cell cycle progression (eg, histone deacetylase inhibitors, Aurora kinase inhibitors). Since such therapies are toxic, more and more recently, targeted therapies are being used in which specific processes in the cell are blocked, without any high toxic load occurs. These include in particular inhibitors of kinases which inhibit the phosphorylation of receptors and signal transduction molecules. An example of this is imatinib, which is used very successfully for the treatment of chronic myeloid leukemia (CML) and gastrointestinal stromal tumors (GIST).
  • CML chronic myeloid leukemia
  • GIST gastrointestinal stromal tumors
  • EGFR kinase and HER2 blocking substances such as erlotinib and VEGFR kinase inhibitors such as sorafenib and sunitinib, which are used in renal cell carcinoma, liver carcinoma or advanced stages of GIST.
  • Bevacizumab inhibits blood vessel growth, which hinders the rapid expansion of a tumor, as it requires a connection to the blood vessel system for a continuously functioning supply and disposal.
  • hypoxia hypoxia
  • FIH factor inhibiting HIF
  • HIF can be degraded via the proteasome apparatus via the Hippel Lindau protein (part of a ubiquitin E3 ligase complex) (Maxwell, Wiesener et al., 1999). In the absence of oxygen, breakdown is avoided, the protein is up-regulated and leads to the transcription or blockade of the transcription of numerous (more than 100) other proteins (Semenza and Wang, 1992, Wang and Semenza, 1995).
  • the transcription factor HIF is formed by the regulated a- and constitutively present aryl hydrocarbon receptor nuclear translocator (ARNT).
  • ARNT aryl hydrocarbon receptor nuclear translocator
  • the HIF subunits are bHLH (basic helix loop helix) proteins that dimerize via their HLH and PAS (per-Arnt-Sim) domain, which starts their transactivating activity (Jiang, Rue et al., 1996 ).
  • HIF ⁇ protein In the major tumor entities, overexpression of the HIF ⁇ protein is correlated with increasing blood vessel density and enhanced VEGF expression (Hirota and Semenza, 2006). At the same time, the glucose metabolism is changed towards glycolysis, and the Krebs cycle is reduced in favor of the production of cell building blocks. This also implies a change in the fat metabolism. Such changes seem to ensure the survival of the tumors. On the other hand, if the activity of HIF is inhibited, then it would be possible to suppress the development of tumors.
  • the object of the present invention was thus to provide novel compounds which act as inhibitors of the transactivating effect of the transcription factor HIF and as such can be used for the treatment and / or prevention of diseases, in particular hyperproliferative and angiogenic diseases such as cancers.
  • WO 2005/030121 -A2 and WO 2007/065010-A2 describe the usefulness of certain pyrazole derivatives for inhibiting the expression of HIF and HIF-regulated genes in tumor cells.
  • WO 2008/141731-A2 WO 2010/054762-A1, WO 2010/054763-A1 and WO 2010/054764-A1 disclose various heteroaryl-substituted pyrazole derivatives as inhibitors of the HIF-regulation pathway for the treatment of cancers.
  • EP 1 310 485-A1 describes disubstituted heteroaryl compounds as TGF ⁇ inhibitors for the treatment of fibroses.
  • WO 2008/097538-A1 discloses certain 2-phenylvinyl-substituted heterocyclic compounds for the treatment of Alzheimer's disease.
