Zu Zwecken einer Isolierung oder Reinigung ist auch die Verwendung pharmazeutisch nicht akzeptabler Salze möglich, beispielsweise von Picraten oder Perchloraten. For purposes of isolation or purification, also the use of non-pharmaceutically acceptable salts is possible, for example Picraten or perchlorates.

However, only the pharmaceutically acceptable salts or the free compound are used therapeutically if appropriate in the form Stufe Prostatatumoren pharmaceutical compositionsso that these are preferred. In Anbetracht der engen Verwandtschaft zwischen der neuen Verbindung in freier Stufe Prostatatumoren und in Form ihrer Salze unter Einschluss Stufe Prostatatumoren als Zwischenprodukte verwendbaren Salze, beispielsweise zur Reinigung und Identifikation der neuen Verbindung, ist eine Bezugnahme Stufe Prostatatumoren die freie Verbindung vorliegend aber so zu verstehen, dass davon auch die entsprechenden Salze, falls geeignet und zweckdienlich, umfasst werden.

In view of the close relationship between the novel compound in free form and in the form of their salts, including the usable as intermediates salts, for example, for purification and identification of the new connection, a reference to the free compound is present but to be understood that it also the corresponding salts, as appropriate and expedient comprises. Die Stufe Prostatatumoren von Proteinen ist seit langem bekannt als eine wesentliche Stufe bei der Differenzierung und Teilung und Zellen.

Single white colonies are picked and viral DNA bacmid is isolated from the bacteria by conventional purification methods for plasmids. Von der transfektierten Zellkultur wird ein Virus enthaltendes Medium gesammelt und zur Infektion zwecks Erhöhung des Titers verwendet.

From the transfected cell culture a virus is collected containing media and used to infect the purpose of increasing the titer. A virus-containing medium obtained after two rounds of infection is used for protein expression in a Stufe Prostatatumoren scale.

Cell pellets of 10 to 20, cm 2 plates, are resuspended in 50 ml ice-cold lysis buffer 25 mM Tris-HCl, pH 7. The centrifuged cell lysate is loaded onto a 2 ml glutathione-sepharose column Stufe Prostatatumoren and washed three times with 10 Stufe Prostatatumoren of 25 mM Tris-HCl, pH 7. Kinaseassay: Kinase Assay:. Tyrosinproteinkinaseassays with purified GST c-Kit are carried out in a final volume of The assay 30 ul is min in well Stufe Prostatatumoren at ambient temperature for 20 under conditions as they are described below, executed and terminated by addition of After examining all samples, a Stufe Prostatatumoren is applied and rinsed each well with ul 0.

Then, by removal of the membranes and washing Stufe Prostatatumoren times on a shaker with 1. The IC 50 values are calculated by linear regression analysis of the percentage inhibition Stufe Prostatatumoren each compound in each case as a double test at four concentrations usually Stufe Prostatatumoren.

Inhibition of the autophosphorylation of the SCF receptor can be measured using, for example, MO7e cells, namely a human promegakaryocytischen leukemia cell line which depends on SCF for proliferation. Identische Mengen an Zelllysaten werden Stufe Prostatatumoren durch sogenanntes Western-Blot unter Verwendung von Antiphosphotyrosinantikörpern analysiert Buchdunger et al.

Nach Auftauen werden die Zellen während maximal 10 bis 12 Passagen für die Experimente verwendet. After thawing, the cells are used during maximally 10 to 12 passages for the experiments. For Zellularassays compounds are dissolved in DMSO and diluted with complete medium to yield a starting concentration of 10 uM, followed by 3-fold serial dilutions are prepared in complete medium. Each provided with 50 ul hole at triple compounds of test compound is added in triplicate to the cells.

Als Kontrolle werden unbehandelte Zellen verwendet. As a control, untreated cells are used. Then, the cell pellets by addition of Für alle Inkubationsstufen werden die Platten Stufe Prostatatumoren Plattenversiegelern Costar bedeckt.

Finally, the plates are washed a further 3 times with Stufe Prostatatumoren buffer and once with deionized water before they are added to The activity of the compound on the Bcr-Abl kinase Stufe Prostatatumoren is expressed Stufe Prostatatumoren the percentage reduction of the Bcr-Abl phosphorylation.

The IC 50 values and IC 90 values are determined from the dose response curves by graphical extrapolation. Die Aktivität von Verbindungen auf die MT mutante Bcr-Abl Kinaseaktivität wird wie oben beschrieben bestimmt, mit der Ausnahme, dass hierbei 32Dcl3 Zellen verwendet werden, die mit mutantem Bcr-Abl anstelle von p Bcr-Abl transfektiert worden sind.

A complete lysis of cells obtained after 10 min Stufe Prostatatumoren ice with occasional Stufe Prostatatumoren. The c-Raf-1 is purified from cell lysates using a ul column packed with Glutathione Sepharose 4B beads and resuspended in ice cold PBS per 2.

Then transfer the bound GST-c-Raf-1 with beads in a column. Die Säule wird einmal mit Lysepuffer und zweimal mit eiskalter Trisgepufferter Kochsalzlösung gewaschen. The column is washed once with lysis buffer and twice with ice cold Tris buffered saline. After addition of ice-cold buffer Stufe Prostatatumoren column flow is stopped to allow for disruption of the interaction of GST-c-Raf-1 with glutathione sepharose beads. Sodann werden Fraktionen 1 ml in vorgekühlten Röhrchen gesammelt.

Then, fractions 1 ml Stufe Prostatatumoren collected in pre-cooled tubes. Using 1 kappa B as a substrate for the c-Raf-1 kinase. LysS bacteria containing the 1 kappa B plasmid are grown to an OD of 0. Thereafter, the solution on Ni agarose Novagen was added and washed the manual by Novagen accordingly. Then, elution of 1 KB from the column is carried out using an Stufe Prostatatumoren buffer 0.
