Description

<div class="application article clearfix" id="description"> New Zealand Paient Spedficaiion for Paient Number 554695 WO 2006/040281 1 PCT/EP2005/055021 88994pct THXAZOLYIi-DXHYDRO INDAZOLES The present invention relates to novel thiazolyldihydroindazoles of the general formula (1) where the radicals R1 to R3 have the meanings given in the claims and the description, to their isomers, to processes for preparing these thiazolyldihydroindazoles, and to the use of the latter as pharmaceuticals. Background to the invention The phosphorylation of proteins and lipids is an important cellular regulation mechanism which plays a role in many different biological processes such as cell proliferation, differentiation, apoptosis, metabolism, inflammation, immune reactions and angiogenesis. More than 500 kinases are encoded in the human genome. In general, tyrosine protein kinases are stimulated by growth factors or other mitogenic signals and phosphorylate proteins which initiate rapid signal transmissions. Serine/threonine protein kinases mostly phosphorylate proteins which crosslink and amplify intracellular signals. Lipid kinases are likewise important switching sites in intracellular signal pathways, with these sites linking various biological processes. A number of protein kinases have already proved to be suitable target mo1ecules for therapeutic intervention in a variety of indications, e.g. cancer and inflammatory and autoimmune diseases. Since a high percentage of the genes involved in the development of WO 2006/040281 2 PCT/EP2005/055021 cancer which have been identified thus far encode kinases, these enzymes are attractive target molecules for the therapy of cancer in particular. Phosphatidylinositol 3-kinases (PI3 kinases) are a subfamily of the lipid kinases and catalyse the transfer of a phosphate radical to the 3' position of the inositol ring of phosphoinositides. They play a crucial role in a large number of cellular processes such as cell growth and differentiation processes, the regulation of cytoskeletal changes and the regulation of intracellular transport processes. The PI3 kinases can be subdivided into different classes on the basis of their in-vitro specificity for particular phosphoinositide substrates. Among the members of the class I PI3 kinases, the a, (3 and 5 PI3 kinases (class IA) are principally activated by receptor tyrosine kinases (RTKs) or soluble tyrosine kinases. On the other hand, the y PI3 kinase (class IB) is principally activated by G(3y subunits which are released from heterotrimeric G proteins following activation of heptahelical receptors. As a result of these differences in the coupling to cell surface receptors, in combination with a more or less restricted expression, the 4 class I PI3 kinases inevitably have very different tasks and functions in the intact organism. Many independent findings indicate that class IA PI3 kinases are involved in uncontrolled processes of cell growth and differentiation. Thus, the first PI3 kinase activity which was detected was associated with the transforming activity of viral oncogenes such as the middle T antigen of polyoma viruses, Src tyrosine kinases or activated growth factors (Workman, Biochem Soc Trans. 2004; 32(Pt 2):393-6). Akt/PKB, which is activated directly by the lipid products of the class I WO 2006/040281 3 ' PCT/EP2005/055021 PI3 kinases and in this way transmits the signals into the cell, is found to be hyperactive in many tumours such as breast cancer and ovarian or pancreatic carcinoma. In addition, it has recently been found that the PIK3 CA gene, which encodes the pllO subunit of Pl3Ka, exhibits a high frequency of mutation in many tumour types such as colon, mammary and lung carcinomas, with some of the mutations being representatively characterized as being activating mutations (Samuels et al. , Science 2004; 304 (5670) : 554) . Detailed description of the invention It has now been found, surprisingly, that compounds of the general formula (I), in which the radicals R1 to R3 have the meanings given below, act as inhibitors of specific cell cycle kinases.

The appropriate amine (0.1 mmol) is then added and the mixture is stirred at RT until the conversion is complete. The reaction mixture is treated with an aqueous 5% solution of potassium carbonate and extracted with dichloromethane. The combined organic phases are dried and evaporated In vacuo. The residue is crystallized from petroleum ether or purified chromatographically. Synthesis method B HATU (0.55 mmol) and diisopropylethylamine (1.8 mmol) are added to a solution of the carboxylic acid (0.35 mmol) in 5 ml of DMF (or dichloromethane or THF) and the mixture is stirred at RT for 15 min. After the appropriate amine (0.39 mmol) has been added, the WO 2006/040281 52 PCT/EP2005/055021 mixture is stirred at RT for 15 h, after which it is treated with aqueous 5% potassium carbonate solution and extracted with dichloromethane. The combined organic phases are dried and evaporated in vacuo. The residue is purified chromatographically. Synthesis method C The synthesis is carried out in analogy with synthesis method B but using triethylamine instead of diisopropylethylamine. Synthesis method D The carboxylic acid is first of all immobilized on a polymer. For this, 12 ml of dichloromethane are added to 1.2 g of PL-TFP resin (1.25 mmol/g, 150-300 jam; Polymer Laboratories), with the appropriate carboxylic acid (1.2 mmol in 6 ml of DMF), DMAP (0.7 mmol in 6 ml of dichloromethane) and 0.8 ml of diisopropylcarbodiimide then being pipetted in consecutively 5 minutes later. The mixture is left to stand at RT for 36 h. The resin is filtered off through a glass frit (porosity 4) and washed 4 x with in each case 15 ml of DMF, 4 x with in each case 20 ml of dichloromethane and 4 x with in each case 20 ml of THF, with the solvent in each case dripping through the glass frit without any vacuum/pressure and with the frit being sucked dry before each new application of solvent. The washed resin is dried at RT and 0.2 mbar for 2 d. Yield of dry resin: 2.204 g. For the reaction of the immobilized carboxylic acid, 110 mg (0.15 mmol) of the resin which has been prepared in this way are initially introduced in 1 ml of dichloromethane and 0.5 ml of DMF after which the amine (0.1 mmol) and diisopropylethylamine (0.1 mmol) are added. The mixture is then stirred slowly at RT for 15 h. After the reaction has come to an end, the resin is filtered off as described above and washed with 8 x 3 ml of dichloromethane.

HCT116 cytotoxicity test The test is based on the reduction of AlamarBlue (Biosource Int., USA) in living (metabolically active) cells to give a fluorometrically detectable product. The substrate can no longer be reduced in the presence of substances which are toxic to the cells, which means that it is not possible to measure any increase in fluorescence. HCT116 (human colon carcinoma cell line) cells are sown in microtiter plates and incubated overnight in culture medium at 37°C and 5% CO2. The test substances are diluted stepwise in medium and added to the cells such that the total volume is 200 ul/well. Cells to which medium, but not substance, is added serve as controls. After an incubation time of 4-6 days, 20 pi of AlamarBlue are added/well and the cells are incubated at 37°C for a further 6-8 h. For measuring the fluorescence, excitation takes place at a wavelength of 545 nm and the emission is measured at 590 nm. EC50 values are calculated using the GraphPad Prism program. All the examples cited have an EC50 (HCT-116) of less than 5 uM. The substances of the present invention are PI3 kinase inhibitors.

Examples of suitable forms for use are tablets, capsules, suppositories, solutions, in particular solutions for injection (s.c., i.v., i.m.) and infusion, juices, emulsions or dispersible powders. In this connection, the proportion of the pharmaceutically active compound(s) should in each case be in the range of 0.1-90% by weight, preferably 0.5-50% by weight, of the total composition, that is in quantities which are sufficient to achieve the dosage range which is specified below. If necessary, the doses mentioned can be given several times a day. Appropriate tablets can be obtained, for example, by mixing the active compound(s) with known auxiliary substances, for example inert diluents, such as calcium carbonate, calcium phosphate or lactose, disintegrants, such as maize starch or alginic acid, binders, such as starch or gelatine, lubricants, such as magnesium stearate or talc, and/or agents for achieving a depot effect, such as carboxymethyl cellulose, cellulose acetate phthalate or polyvinyl acetate. The tablets can also comprise several layers. Correspondingly, sugar-coated tablets can be produced by coating cores, which have been prepared in analogy with tablets, with agents which are customarily used in sugar coatings, for example collidone or shellac, gum arabic, talc, titanium dioxide or sugar. The core can also comprise several layers in order to achieve a depot effect or to avoid incompatibilities. In the same way, the sugar coating can also comprise several layers in order to achieve a depot effect, with it being possible to use the auxiliary substances which are mentioned above in the case of the tablets. Juices of the active compounds or active compound WO 2006/040281 120 PCT/EP2005/055021 combinations according to the invention can additionally comprise a sweetening agent, such as saccharine, cyclamate, glycerol or sugar as well as a taste-improving agent, e.g. flavouring agents such as vanillin or orange extract. They can also comprise suspension aids or thickeners, such as sodium carboxymethyl cellulose, wetting agents, for example condensation products of fatty alcohols and ethylene oxide, or protectants such as p-hydroxybenzoates. Injection and infusion solutions are produced in a customary manner, e.g. while adding isotonizing agents, preservatives, such as p-hydroxybenzoates, or stabilizers, such as alkali metal salts of ethylenediaminetetraacetic acid, where appropriate using emulsifiers and/or dispersants, with it being possible, for example, to employ, where appropriate, organic solvents as solubilizing agents or auxiliary solvents when using water as diluent, and aliquoted into injection bottles or ampoules or infusion bottles. The capsules, which comprise one or more active compounds or active compound combinations, can, for example, be produced by mixing the active compounds with inert carriers, such as lactose or sorbitol, and encapsulating the mixture in gelatine capsules. Suitable suppositories can be produced, for example, by mixing with excipients which are envisaged for this purpose, such as neutral fats or polyethylene glycol, or their derivatives. Auxiliary substances which may be mentioned by way of example are water, pharmaceutically unobjectionable organic solvents, such as paraffins (e.g. petroleum fractions), oils of vegetable origin (e.g. groundnut oil or sesame oil), monofunctional or polyfunctional alcohols (e.g. ethanol or glycerol), carrier substances such as natural mineral powders (e.g. kaolins, WO 2006/040281 121 PCT/EP2005/055021 argillaceous earths, talc and chalk), synthetic mineral powders (e.g. highly disperse silicic acid and silicates), sugars (e.g. cane sugar, lactose and grape sugar), emulsifiers (e.g. lignin, sulphite waste liquors, methyl cellulose, starch and polyvinylpyrrolidone) and glidants (e.g. magnesium stearate, talc, stearic acid and sodium lauryl sulphate). Administration is effected in a customary manner, preferably orally or transdermally, in particular and preferably orally. In the case of oral use, the tablets can naturally also comprise, in addition to the abovementioned carrier substances, additives such as sodium citrate, calcium carbonate and dicalcium phosphate together with a variety of further substances such as starch, preferably potato starch, gelatine and the like. It is furthermore also possible to use glidants, such as magnesium stearate, sodium lauryl sulphate and talc, for the tableting. In the case of aqueous suspensions, a variety of taste improvers or dyes can also be added to the active compounds in addition to the abovementioned auxiliary substances. For parenteral administration, it is possible to employ solutions of the active compounds while using suitable liquid carrier materials. The dosage for intravenous administration is 1-1000 mg per hour, preferably between 5 and 500 mg per hour. Despite this, it may be necessary, where appropriate, to diverge from the abovementioned quantities, depending on the body weight or the nature of the route of administration, on the individual response to the medicament, on the nature of its formulation and on the time or interval at which the administration is effected. Thus, it may, in some cases, be sufficient to make do with less than the previously mentioned lowest WO 2006/040281 122 PCT/EP2005/055021 quantity whereas, in other cases, the abovementioned upper limit has to be exceeded. When relatively large quantities are being administered, it may be advisable to divide these into several single doses which are given over the course of the day.
