Gebiet der Erfindung Field of the Invention. The present invention relates to the use of compounds and compositions for inhibiting cell proliferative disorders. Hintergrund der Erfindung Background of the Invention. The following description of the background of the invention is provided to aid in understanding the invention, but it is not dh Psoriasis biologisch that it describes or represents dh Psoriasis biologisch art for the invention.

The Kit signaling is critical for fetal gonadal development, and continues to play a role in fertility of adults Mauduit et al Human Reproduction Update. Die Spermatogenese ist in Abwesenheit von SCF Ohta et al. Spermatogenesis is in the absence of SCF Ohta et al Development Or the ability of Kit via the PI3 kinase pathway Blume-Jensen et al Nature Genetics. Kissel et al EMBO Journal Es wurde ob es Juckreiz bei, dass die Expression von Kit in subfertilen Hoden geringer ist als in normalem Hodengewebe Feng et al.

These observations suggest that Kit kinase inhibitors would reduce both male and female fertility. As a key mediator of mast cell function, Kit may play a role in pathologies associated with mast cells in combination. Mast cells were also in the rejection of allogeneic liver transplant Yamaguchi et al Hepatology.

These observations suggest that Kit kinase inhibitors may help prevent organ rejection and fibrosis. Mastzellen wurden ebenfalls dh Psoriasis biologisch der Pathologie von Multipler Sklerose Secor et al.

Mast cells have also been implicated in the pathology of multiple sclerosis Secor et al J. In both cases, the pathology of the disease was significantly attenuated relative dh Psoriasis biologisch mice with normal Kit and mast cell populations. Thus can the role of mast cells in these diseases suggests that Kit kinase inhibitors might be useful therapeutics.

Cellular signal transduction is a fundamental mechanism are passed through the extracellular stimuli into the interior of cells and subsequently regulate diverse cellular processes below.

One of the key biochemical mechanisms of signal transduction involves the reversible phosphorylation of proteins. Phosphorylation of polypeptides regulates the activity of mature proteins by altering their structure and function. In proteins, phosphate is most often to dh Psoriasis biologisch hydroxyl OH of serine, threonine or tyrosine amino acids.

Enzymes that mediate phosphorylation of cellular effectors generally fall under two classes. The first class consists of protein kinases which transfer a phosphate group from adenosine triphosphate to protein substrates.

Die zweite Klasse besteht aus Proteinphosphatasen, die Phosphatreste von Phosphorylproteinsubstraten hydrolysieren. The second class consists of protein phosphatases which hydrolyze phosphate moieties from phosphoryl. Die entgegengesetzten Psoriasis medizinische Behandlung von Proteinkinasen und Proteinphosphatasen gleichen den Fluss click Signalen in Signaltransduktionsprozessen aus und regulieren diesen.

The opposing functions of protein kinases and protein phosphatases are similar to dh Psoriasis biologisch flow of signals in signal transduction processes and regulate this. Proteinkinasen und Proteinphosphatasen werden im Allgemeinen in zwei Gruppen aufgeteilt: Proteine dh Psoriasis biologisch Rezeptor- und Nicht-Rezeptorart. Protein kinases and Eplan Psoriasis phosphatases are generally divided into two groups: Most protein tyrosine phosphatases from receptor type contain two conserved catalytic domains, each of which comprises a segment of amino acid residues.

Receptor may be further sub-classified based on the difference in the amino acid sequence of their extracellular domains. Acad Sci USA Protein kinases and protein phosphatases are also typically divided based on the amino acids on which they act in three classes.

Einige katalysieren dh Psoriasis biologisch Addition oder Hydrolyse von Phosphat nur bei Serin oder Threonin, einige katalysieren die Addition oder Hydrolyse von Phosphat nur bei Tyrosin und einige katalysieren die Addition oder Hydrolyse von Phosphat bei Serin, Threonin Zinksalbe Psoriasis Tyrosin.

Some catalyze the addition or hydrolysis of phosphate on serine or threonine, some catalyze the addition or hydrolysis of phosphate on tyrosine and some catalyze the addition or hydrolysis of phosphate on serine, threonine and tyrosine. Tyrosine kinases can the catalytic activity of other protein kinases that are involved in cell proliferation regulate.

Protein kinases with inappropriate activity are also involved in some types of cancer. Abnormally elevated levels of cell proliferation is associated with receptor and non-receptor protein kinases with unregulated activity. In addition to their role in cellular proliferation, it is believed that protein kinases dh Psoriasis biologisch involved in cellular differentiation processes.

There are reports on the expression of c-kit in normal astrocytes Natali, et al, Im letzteren Fall wurde ein hoher Grad an c-kit Expression in Dh Psoriasis biologisch hoher Tumorklasse beobachtet Kristt, et al.

In the latter case, a high degree of c-kit expression was observed in tumors of high tumor grade observed Kristt, et al,Neuro.

In addition, there are conflicting reports of c-kit and SCF expression in neuroblastomas. Eine Studie fand, dass Neuroblastomzelllinien oft SCF, aber selten c-kit exprimieren.

One study found that neuroblastoma cell lines often express SCF, but rarely c-kit. Im Gegensatz dazu haben andere Studien Cohen, et al. In contrast, other studies Cohen, et al,Blood. Thus, c-kit kinase inhibitors as a means to treat these cancers may prove therapeutically useful.

As mentioned above, dh Psoriasis biologisch has been reported that SCF dh Psoriasis biologisch known as mast cell growth factor stimulation of c-kit for growth and development of mast cells essential is Hamel, et al,Reinigung Leber Psoriasis. Mice with mutations of c-kit that attenuate its signaling activity, clearly showing fewer mast cells in their skin Tsujimura, dh Psoriasis biologisch, Pathol Int Excessive activation dh Psoriasis biologisch c-kit could be related to diseases arising from excessive abundance of mast cells in conjunction.

Mastocytosis is the term used dh Psoriasis biologisch describe a heterogeneous series of disorders characterized by excessive mast cell proliferation distinguished Metcalfe,J.

Clin Immunol Aller There was an increased c-kit expression on mast cells from patients with aggressive mastocytosis, but not on mast cells from patients with indolent mastocytosis reported Nagata, et al,Mastocytosis Leuk. Es wurde gezeigt, dass SCF auf Stromazellen als dh Psoriasis biologisch Protein exprimiert wird und seine Dh Psoriasis biologisch durch fibrogene Wachstumsfaktoren, wie zum Beispiel PDGF, induziert werden kann Hiragun, et al.

It has been demonstrated that SCF is expressed on stromal cells as a membrane-bound protein, and its expression can be induced by fibrogenic growth factors such as PDGF Hiragun, et al. Es Kiewer Institut für Psoriasis Dermatosen ebenfalls gezeigt, dass es als membrangebundenes Protein auf Keratinozyten in normaler Haut exprimiert wird.

It has also been shown that it is expressed as a membrane-bound protein on keratinocytes in normal skin. In the skin of patients with mastocytosis but an increased amount of soluble Dh Psoriasis biologisch has been observed Longley, et al,New Engl J Med It has been reported dh Psoriasis biologisch Mastzellchymase membrane-associated SCF to a soluble and splits biologically active form. This mast cell-mediated process could serve to create a feedback loop to enhance mast cell proliferation and function Longley, et al,Proc Natl Acad Sci Transgenic mice overexpressing a form of SCF that can not be proteolytically released from keratinocytes did dh Psoriasis biologisch develop mastocytosis, while similar animals expressing normal SCF in keratinocytes, a phenotype exhibited, the human cutaneous mastocytosis resembled Kunisada, et al.

The formation of large amounts of soluble SCF can, in some patients to the pathology, which is in communication with mastocytosis, contribute and the present invention can treat or dh Psoriasis biologisch such disorders by dh Psoriasis biologisch the interaction between SCF and c-kit kinase. Several different mutations read article the c-kit RTK that result dh Psoriasis biologisch constitutive kinase activity have been found in human and rodent mast cell tumor cell lines Furitsu, et al, dh Psoriasis biologisch, J Clin Invest Additionally, activating mutations of the c-kit dh Psoriasis biologisch in peripheral mononuclear cells that had been isolated from patients with mastocytosis and click at this page hematologic disorders Nagata, et al,Mastocytosis Leuk.

It is therefore prove that the inhibition of c-kit kinase in the treatment of these disorders makes an excellent therapeutic role. In some patients, activating mutations of the c-kit RTK may be responsible for the pathogenesis of the disease and these patients can be prepared by the modulation of the SCF interaction with c-kit kinase treated or their diseases prevented.

It has been shown that the SCF activation of c-kit, the mast cell apoptosis which may be critical for maintaining cutaneous Mastzellhomeostase prevented Iemura, et al,Amer J. Inhibition of mast cell apoptosis could lead to the accumulation of mast cells, which is associated with mastocytosis. Thus provides the observation of c-kit activation resulting from overexpression of the receptor, excessive formation of soluble SCF, or mutations of the c-kit gene that activate its kinase constitutive, an explanation for the inhibition of the kinase dh Psoriasis biologisch of c- kit, the number link mast cells is reduced, and for patients with mastocytosis provides a benefit.

Mast cells and eosinophils dh Psoriasis biologisch at infection with parasites, allergies, inflammation and asthma key cells represent Thomas, et al,Gen. It has been demonstrated that SCF essential for mast go here development, survival and growth Kitamura, et al,Int Arch Aller Immunol In addition, SCF cooperates with the eosinophil-specific regulator, IL-5 together, to increase the development of eosinophil progenitors Metcalfe, et al,Proc Natl Acad Sci, USA Es wurde ebenfalls berichtet, dass SCF Mastzellen dazu veranlasst Faktoren zu sekretieren Okayama, et al.

It has also been reported that SCF mast cells to secrete factors causes Okayama, et click the following article,Int Arch Aller Immunol In diesem Zusammenhang reguliert SCF direkt und indirekt die Aktivierung von sowohl Mastzellen als auch Eosinophilen.

In this regard, SCF directly and indirectly regulates activation of both mast cells and eosinophils. SCF induces mediator release from mast cells, as well as priming these cells for IgE-induced degranulation Columbo, et al,J. In addition to inducing histamine release from mast cells Luckacs, et al,J. SCF also directly influences the adhesion of both mast cells Dastych, et al,J. Thus, SCF can influence the primary cells involved in allergy and asthma through multiple mechanisms.

Visit web page present, corticosteroids are the most effective treatment for chronic rhinitis and inflammation associated with allergies in conjunction Naclerio, et al,JAMA These agents act via multiple mechanisms including reduction of circulating and infiltrating mast cells and eosinophils, and diminished survival of eosinophils associated with inhibition of cytokine dh Psoriasis biologisch Meltzer,Aller.

It has also been reported that steroids inhibit the expression of SCF by fibroblasts and resident connective tissue cells, resulting dh Psoriasis biologisch decreased survival of mast cells Finotto, et al,J. Because of the mutual regulation of mast cell and eosinophil function, and the role that SCF can play in this regulation, inhibition of c-kit kinase provides a means to treat allergy-associated chronic rhinitis, inflammation and asthma.
