- the serine/threonine kinase family includes members that control cell growth, migration, differentiation, gene expression, muscle contraction, glucose metabolism, cellular protein synthesis, and regulation of the cell cycle.
- Aurora kinases are a family of serine/threonine kinases that are believed to play a key role in the protein phosphorylation events that are essential for the completion of essential mitotic events.
- the Aurora kinase family is made up of three key members: Aurora A, B and C (also known as Aurora-2, Aurora- 1 and Aurora-3 respectively).

- Aurora A is amplified and transcript/protein is highly expressed in a majority of human tumor cell lines and primary colorectal, breast and other tumors. It has been shown that Aurora A overexpression leads to genetic instability shown by amplified centrosomes and significant increase in aneuploidy and transforms Ratl fibroblasts and mouse NIH3T3 cells in vitro. Aurora A-transformed NIH3T3 cells grow as tumors in nude mice (Bischoff, J.R., and Plowman, G.D., Trends Cell Biol. 9 (1999) 454-459; Giet, R., and Prigent, C, J.

- the compounds of formula I can contain one or several chiral centers and can then be present in a racemic or in an optically active form.
- the racemates can be separated according to known methods into the enantiomers. For instance, diastereomeric salts which can be separated by crystallization are formed from the racemic mixtures by reaction with an optically active acid such as e.g. D- or L- camphorsulfonic acid. Alternatively separation of the enantiomers can also be achieved by using chromatography on chiral HPLC-phases which are commercially available.
- the compounds of formula I and their pharmaceutically acceptable salts possess valuable pharmacological properties. It has been found that said compounds show activity as inhibitors of the Aurora kinase family and also show anti-proliferative activity. Consequently the compounds of the present invention are useful in the therapy and/or prevention of illnesses with known over- expression of kinases of the Aurora family preferably Aurora A, especially in the therapy and / or prevention of illnesses mentioned above.
- the activity of the present compounds as inhibitors of the Aurora kinase family is demonstrated by the following biological assay:
- Aurora A is a serine threonine kinase involved in spindle assembly and chromosome segregation.
- the assay is a typically ELISA-type assay where biotinylated substrate (PKB-GSK2) is phosphorylated. Phosphorylation is detected by peroxidase (POD) labelled polyclonal antibody (PAK ⁇ M-Ig>S-IgG-POD) and phosphopeptide monoclonal antibody (Mab) (MAK ⁇ P-GSK>M-27E5-IgG). The assay is validated for IC 50 determination.

- Negative control without ATP.
- the CellTiter-GloTM Luminescent Cell Viability Assay (Promega) is a homogeneous method of determining the number of viable cells in culture based on quantitation of the ATP present, which signals the presence of metabolically active cells.
- the cells were seeded in 384 well plates, 1000 cells per well, in the same medium. The next day the test compounds were added in various concentrations ranging from 30 ⁇ M to 0.0015 ⁇ M (10 concentrations, 1:3 diluted).
- the CellTiter-GloTM assay was done according to the instructions of the manufacturer (CellTiter-GloTM Luminescent Cell Viability Assay, from Promega). In brief: the cell-plate was equilibrated to room temperature for approximately 30 minutes and than the CellTiter-GloTM reagent was added. The contents were carefully mixed for 15 minutes to induce cell lysis. After 45 minutes the luminescent signal was measured in Victor 2, (scanning multiwell spectrophotometer, Wallac).

- the compounds according to this invention and their pharmaceutically acceptable salts can be used as medicaments, e.g. in the form of pharmaceutical compositions.
- the pharmaceutical compositions can be administered orally, e.g. in the form of tablets, coated tablets, dragees, hard and soft gelatine capsules, solutions, emulsions or suspensions.
- the administration can, however, also be effected rectally, e.g. in the form of suppositories, or parenterally, e.g. in the form of injection solutions.
- compositions can be obtained by processing the compounds according to this invention with pharmaceutically inert, inorganic or organic carriers.
- Lactose, corn starch or derivatives thereof, talc, stearic acids or it's salts and the like can be used, for example, as such carriers for tablets, coated tablets, dragees and hard gelatine capsules.
- Suitable carriers for soft gelatine capsules are, for example, vegetable oils, waxes, fats, semi-solid and liquid polyols and the like. Depending on the nature of the active substance no carriers are, however, usually required in the case of soft gelatine capsules.
- Suitable carriers for the production of solutions and syrups are, for example, water, polyols, glycerol, vegetable oil and the like.
- Suitable carriers for suppositories are, for example, natural or hardened oils, waxes, fats, semi-liquid or liquid polyols and the like.

- N-(l-ethyl-3,3-dimethyl-5-nitro-2-oxo-2,3-dihydro-lH-indol-6-yl)-acetamide (5.2 g, 17.85 mmol) was dissolved in ethanol (40 ml). After addition of hydrochloric acid (25 %, 8 ml, 81.44 mmol) the mixture was stirred under reflux for 3 h. The reaction mixture was allowed to cool down to room temperature and then quenched with water (80 ml). The yellow precipitate was isolated by suction and washed with ethanol/water (1:1).
- 5,6-diamino-3,3-dimethyl-l -propyl- l,3-dihydro-indol-2-one was prepared in an analogous 6-step-synthesis as described for 5,6-diammo-l-ethyl-3,3-dimethyl-l,3- dihydro-indol-2-one.
