Definitions

  • the present invention relates to new quinoxaline, quinoline and quinazoline compounds of general formula (1 )
  • the aim of the present invention is to indicate new compounds which can be used for the prevention and/or treatment of diseases characterised by excessive or abnormal cell proliferation.
  • the compounds according to the invention are characterised by a powerful inhibitory effect on PDK 1 and a high efficacy against tumour cells, e.g. prostate carcinoma cells, which is mediated through inhibiting PDK 1 .
  • tumour cells e.g. prostate carcinoma cells
  • the compounds have good solubility and good selectivity with regard to other signal and cell cycle kinases.
  • the importance of the PI3K-PDK1 -AKT pathway with its frequent aberrations (PTEN loss, PI3K mutation) in the major tumor indications is described in numerous scientific publications (e.g. Samuels et al. 2004; Science; 304: 554; Samuels and Velculescu 2004; Cell cycle 3; 17-19; Samuels et al. 2005; Cancer Cell; 7: 561 -573).
  • PDK1 alterations (mutations, CN gains) are rarely found isolated from other pathway alterations so that the importance of this target thrives from the fact that it acts as a central signaling node in a frequently altered pathway.
  • Active PI3K phosphorylates second messengers like Phosphatidylinositol(4.5)- bisphosphate (Ptdlns(4.5)P 2 ) to Ptdlns(3.4.5)P 3 , or Ptdlns(4)P to Ptdlns(3.4,)P 2 .
  • Ptdlns(4.5)P 2 Phosphatidylinositol(4.5)P 2
  • Ptdlns(4.5)P 2 Ptdlns(3.4.5)P 3
  • Ptdlns(4)P Ptdlns(3.4,)P 2 .
  • Such PI3K products recruit AKT and PDK1 kinases via their PH-domains (which bind the PI3 kinase products) to the plasma membrane and allow PDK1 to phosphorylate Thr308 of AKT and thereby activate the enzyme.
  • a second step important for additional AKT activation and/or AKT-substrate selection is mediated by the mTOR/rictor/SIN1 complex which phosphorylates the hydrophobic motif of AKT at Ser473.
  • Activated AKT regulates several other proteins, which are involved in cell proliferation, growth and survival.
  • PDK1 has other substrates located in the cytoplasm, e.g. p70S6K, p90RSK, PKCs and SGK, which are also implicated in regulating cell proliferation and cell survival.
  • the activation of these kinases is not dependent on phosphatidylinositols in vitro and functions properly in cells where the PDK1 -PH-domain had been destroyed by knock-in mutation (McManus et al. 2004, EMBO J. 23, 2071 -2082).
  • PDK1 mouse mutants also see Bayascas 2008; Cell cycle 7; 2978-2982).
  • PDK1 substrates (AKT, p90RSK) act at the crossroad of two important cancer signaling pathways.
  • a potent and selective inhibitor of the PDK1 kinase is predicted to inhibit tumor growth, delay relapse, or even induce objective tumor responses (i.e. complete or partial tumor shrinkage) in cancer patients.
  • compounds of general formula (1 ) wherein the groups R 1 to R 4 , Q a , Q b , Q H , L and n are defined as stated hereinafter act as inhibitors of specific signal enzymes which are involved in controlling the proliferation of cells.
  • the compounds according to the invention may be used for example for the treatment of diseases which are connected with the activity of these signal enzymes and are characterised by excessive or abnormal cell proliferation.

Description

HETEROCYCLIC CARBOXYLIC ACID AMIDES AS PDK1 INIHIBITORS
The present invention relates to new quinoxaline, quinoline and quinazoline compounds of general formula (1 )
Figure imgf000002_0001
(1 )
wherein the groups R1 to R4, Qa, Qb, QH, L and n have the meanings given in the claims and specification, which are suitable for the treatment of diseases characterised by excessive or abnormal cell proliferation, pharmaceutical preparations containing such compounds and their use as medicaments. The compounds according to the invention exhibit an inhibitory effect on the serine/threonine kinase PDK 1 Background to the invention
Quinazolines as PDK1 inhibitors are described for example in WO 2010/0071 14 and WO 2010/0071 16.
The aim of the present invention is to indicate new compounds which can be used for the prevention and/or treatment of diseases characterised by excessive or abnormal cell proliferation. The compounds according to the invention are characterised by a powerful inhibitory effect on PDK 1 and a high efficacy against tumour cells, e.g. prostate carcinoma cells, which is mediated through inhibiting PDK 1 . As well as the inhibitory effect and cell potency the compounds have good solubility and good selectivity with regard to other signal and cell cycle kinases. The importance of the PI3K-PDK1 -AKT pathway with its frequent aberrations (PTEN loss, PI3K mutation) in the major tumor indications is described in numerous scientific publications (e.g. Samuels et al. 2004; Science; 304: 554; Samuels and Velculescu 2004; Cell cycle 3; 17-19; Samuels et al. 2005; Cancer Cell; 7: 561 -573).
PDK1 alterations (mutations, CN gains) are rarely found isolated from other pathway alterations so that the importance of this target thrives from the fact that it acts as a central signaling node in a frequently altered pathway.
Active PI3K phosphorylates second messengers like Phosphatidylinositol(4.5)- bisphosphate (Ptdlns(4.5)P2) to Ptdlns(3.4.5)P3, or Ptdlns(4)P to Ptdlns(3.4,)P2. Such PI3K products recruit AKT and PDK1 kinases via their PH-domains (which bind the PI3 kinase products) to the plasma membrane and allow PDK1 to phosphorylate Thr308 of AKT and thereby activate the enzyme. A second step important for additional AKT activation and/or AKT-substrate selection is mediated by the mTOR/rictor/SIN1 complex which phosphorylates the hydrophobic motif of AKT at Ser473. Activated AKT regulates several other proteins, which are involved in cell proliferation, growth and survival.
Besides AKT, PDK1 has other substrates located in the cytoplasm, e.g. p70S6K, p90RSK, PKCs and SGK, which are also implicated in regulating cell proliferation and cell survival. The activation of these kinases is not dependent on phosphatidylinositols in vitro and functions properly in cells where the PDK1 -PH-domain had been destroyed by knock-in mutation (McManus et al. 2004, EMBO J. 23, 2071 -2082). For a review on PDK1 mouse mutants also see Bayascas 2008; Cell cycle 7; 2978-2982).
In conclusion, PDK1 substrates (AKT, p90RSK) act at the crossroad of two important cancer signaling pathways.
A potent and selective inhibitor of the PDK1 kinase is predicted to inhibit tumor growth, delay relapse, or even induce objective tumor responses (i.e. complete or partial tumor shrinkage) in cancer patients.
Detailed description of the invention
It has been found that, surprisingly, compounds of general formula (1 ) wherein the groups R1 to R4, Qa, Qb, QH, L and n are defined as stated hereinafter act as inhibitors of specific signal enzymes which are involved in controlling the proliferation of cells. Thus, the compounds according to the invention may be used for example for the treatment of diseases which are connected with the activity of these signal enzymes and are characterised by excessive or abnormal cell proliferation.
The present invention therefore relates to compounds of general formula (1 )

Terms that are not specifically defined here have the meanings that are apparent to the skilled man in the light of the overall disclosure and the context as a whole.
As used herein, the following definitions apply, unless stated otherwise:
The use of the prefix Cx-y, wherein x and y each represent a natural number (x < y), indicates that the chains or ring structure or combination of chains and ring structure as a whole, specified and mentioned in direct association, may consist of a maximum of y and a minimum of x carbon atoms.
The indication of the number of members in groups that contain one or more heteroatom(s) (heteroalkyl, heteroaryl, heteroarylalkyl, heterocyclyl, heterocyclylalkyl) relates to the total atomic number of all the ring members or chain members or the total of all the ring and chain members.
Alkyl denotes monovalent, saturated hydrocarbon chains, which may be present in both straight-chain (unbranched) and branched form. If an alkyl is substituted, the substitution may take place independently of one another, by mono- or polysubstitution in each case, on all the hydrogen-carrying carbon atoms.
The term "C1-5-alkyl" includes for example H3C-, H3C-CH2-, H3C-CH2-CH2-,
H3C-CH(CH3)-, H3C-CH2-CH2-CH2-, H3C-CH2"CH(CH3)-, H3C-CH(CH3)-CH2-, H3C-C(CH3)2_, H3C-CH2-CH2-CH2-CH2-, H3C-CH2"CH2-CH(CH3)-, H3C-CH2-CH(CH3)-CH2-, H3C-CH(CH3)-CH2-CH2-, H3C-CH2-C(CH3)2-, H3C-C(CH3)2-CH2-, H3C-CH(CH3)-CH(CH3)- and H3C-CH2-CH(CH2CH3)-.
Further examples of alkyl are methyl (Me; -CH3), ethyl (Et; -CH2CH3), 1 -propyl (n-propyl; n-Pr; -CH2CH2CH3) , 2-propyl (/'-Pr; /'so-propyl; -CH(CH3)2), 1 -butyl (n-butyl; n-Bu; -CH2CH2CH2CH3), 2-methyl-1 -propyl (/'so-butyl; /-Bu; -CH2CH(CH3)2), 2-butyl (sec-butyl; sec-Bu; -CH(CH3)CH2CH3), 2-methyl-2-propyl (ferf-butyl; f-Bu; -C(CH3)3), 1 -pentyl (n-pentyl; -CH2CH2CH2CH2CH3) , 2-pentyl (-CH(CH3)CH2CH2CH3), 3-pentyl (-CH(CH2CH3)2), 3-methyl-1 -butyl (/so-pentyl; -CH2CH2CH(CH3)2), 2-methyl-2-butyl (-C(CH3)2CH2CH3), 3-methyl-2-butyl (-CH(CH3)CH(CH3)2), 2,2-dimethyl-1 -propyl (neo-pentyl; -CH2C(CH3)3), 2-methyl-1 -butyl (-CH2CH(CH3)CH2CH3), 1 -hexyl (n-hexyl; -CH2CH2CH2CH2CH2CH3), 2-hexyl (-CH(CH3)CH2CH2CH2CH3), 3-hexyl (-CH(CH2CH3)(CH2CH2CH3)), 2-methyl-2-pentyl (-C(CH3)2CH2CH2CH3), 3-methyl-2-pentyl (-CH(CH3)CH(CH3)CH2CH3) , 4-methyl-2-pentyl (-CH(CH3)CH2CH(CH3)2), 3-methyl-3-pentyl (-C(CH3)(CH2CH3)2), 2-methyl-3-pentyl (-CH(CH2CH3)CH(CH3)2), 2,3-dimethyl-2-butyl (-C(CH3)2CH(CH3)2), 3 , 3-dimethyl-2-butyl (-CH(CH3)C(CH3)3), 2,3-dimethyl-l -butyl (-CH2CH(CH3)CH(CH3)CH3), 2,2-dimethyl-l -butyl

By the terms propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl etc. without any further definition are meant saturated hydrocarbon groups with the corresponding number of carbon atoms, wherein all isomeric forms are included.
The above definition for alkyi also applies if alkyi is a part of another group such as for example Cx-y-alkylamino or Cx-y-alkyloxy.
The term alkylene can also be derived from alkyi. Alkylene is bivalent, unlike alkyi, and requires two binding partners. Formally, the second valency is produced by removing a hydrogen atom in an alkyi. Corresponding groups are for example -CH3 and -CH2, -CH2CH3 and -CH2CH2 or >CHCH3 etc.
Th e term "C1-4-alkylene" includes for example -(CH2)-, -(CH2-CH2)-, -(CH(CH3))-, -(CH2-CH2-CH2)-, -(C(CH3)2)-, -(CH(CH2CH3))-, -(CH(CH3)-CH2)-, -(CH2-CH(CH3))-, -(CH2-CH2-CH2-CH2)-, -(CH2-CH2-CH(CH3))-, -(CH(CH3)-CH2-CH2)-,

1 ,3-dimethylpropylene, hexylene etc.
By the generic terms propylene, butylene, pentylene, hexylene etc. without any further definition are meant all the conceivable isomeric forms with the corresponding number of carbon atoms, i.e. propylene includes 1 -methylethylene and butylene includes 1 -methylpropylene, 2-methylpropylene, 1 , 1 -dimethylethylene and 1 ,2-dimethylethylene. The above definition for alkylene also applies if alkylene is part of another group such as for example in HO-Cx-y-alkylenamino or H2N-Cx-y-alkylenoxy.
Unlike alkyl, alkenyl consists of at least two carbon atoms, wherein at least two adjacent carbon atoms are joined together by a C-C double bond. If in an alkyl as hereinbefore defined having at least two carbon atoms, two hydrogen atoms on adjacent carbon atoms are formally removed and the free valencies are saturated to form a second bond, the corresponding alkenyl is formed.
Examples of alkenyl are vinyl (ethenyl), prop-1 -enyl, allyl (prop-2-enyl), isopropenyl, but-1 -enyl, but-2-enyl, but-3-enyl, 2-methyl-prop-2-enyl, 2-methyl-prop-1 -enyl, 1 -methyl-prop-2-enyl, 1 -methyl-prop-1 -enyl, 1 -methylidenepropyl, pent-1 -enyl, pent-2-enyl, pent-3-enyl, pent-4-enyl, 3-methyl-but-3-enyl, 3-methyl-but-2-enyl, 3-methyl-but-1 -enyl, hex-1 -enyl, hex-2-enyl, hex-3-enyl, hex-4-enyl, hex-5-enyl, 2,3-dimethyl-but-3-enyl, 2,3-dimethyl-but-2-enyl, 2-methylidene-3-methylbutyl, 2,3-dimethyl-but-1 -enyl, hexa-1 ,3-dienyl, hexa-1 ,4-dienyl, penta-1 ,4-dienyl, penta- 1 ,3-dienyl, buta-1 ,3-dienyl, 2,3-dimethylbuta-1 ,3-diene etc.
By the generic terms propenyl, butenyl, pentenyl, hexenyl, butadienyl, pentadienyl, hexa- dienyl, heptadienyl, octadienyl, nonadienyl, decadienyl etc. without any further definition are meant all the conceivable isomeric forms with the corresponding number of carbon atoms, i.e. propenyl includes prop-1 -enyl and prop-2-enyl, butenyl includes but-1 -enyl, but-2-enyl, but-3-enyl, 1 -methyl-prop-1 -enyl, 1 -methyl-prop-2-enyl etc.
Alkenyl may optionally be present in the cis or trans or £ or Z orientation with regard to the double bond(s).
The above definition for alkenyl also applies when alkenyl is part of another group such as for example in Cx-y-alkenylamino or Cx-y-alkenyloxy. Unlike alkylene, alkenylene consists of at least two carbon atoms, wherein at least two adjacent carbon atoms are joined together by a C-C double bond. If in an alkylene as hereinbefore defined having at least two carbon atoms, two hydrogen atoms at adjacent carbon atoms are formally removed and the free valencies are saturated to form a second bond, the corresponding alkenylene is formed.
Examples of alkenylene are ethenylene, propenylene, 1 -methylethenylene, butenylene, 1 -methylpropenylene, 1 ,1 -dimethylethenylene, 1 ,2-dimethylethenylene, pentenylene, 1 ,1 -dimethylpropenylene, 2,2-dimethylpropenylene, 1 ,2-dimethylpropenylene, 1 ,3-dimethylpropenylene, hexenylene etc.
By the generic terms propenylene, butenylene, pentenylene, hexenylene etc. without any further definition are meant all the conceivable isomeric forms with the corresponding number of carbon atoms, i.e. propenylene includes 1 -methylethenylene and butenylene includes 1 -methylpropenylene, 2-methylpropenylene, 1 ,1 -dimethylethenylene and 1 ,2-dimethylethenylene.
Alkenylene may optionally be present in the c/'s or trans or £ or Z orientation with regard to the double bond(s).
The above definition for alkenylene also applies when alkenylene is a part of another group as in for example HO-Cx-y-alkenylenamino or H2N-Cx-y-alkenylenoxy.
Unlike alkyl, alkynyl consists of at least two carbon atoms, wherein at least two adjacent carbon atoms are joined together by a C-C triple bond. If in an alkyl as hereinbefore defined having at least two carbon atoms, two hydrogen atoms in each case at adjacent carbon atoms are formally removed and the free valencies are saturated to form two further bonds, the corresponding alkynyl is formed.
Examples of alkynyl are ethynyl, prop-1 -ynyl, prop-2-ynyl, but-1 -ynyl, but-2-ynyl, but-3-ynyl, 1 -methyl-prop-2-ynyl, pent-1 -ynyl, pent-2-ynyl, pent-3-ynyl, pent-4-ynyl, 3-methyl-but-1 -ynyl, hex-1 -ynyl, hex-2-ynyl, hex-3-ynyl, hex-4-ynyl, hex-5-ynyl etc.
By the generic terms propynyl, butynyl, pentynyl, hexynyl, heptynyl, octynyl, nonynyl, decynyl etc. without any further definition are meant all the conceivable isomeric forms with the corresponding number of carbon atoms, i.e. propynyl includes prop-1 -ynyl and prop-2-ynyl, butynyl includes but-1 -ynyl, but-2-ynyl, but-3-ynyl, 1 -methyl-prop-1 -ynyl, 1 -methyl-prop-2-ynyl, etc.
If a hydrocarbon chain carries both at least one double bond and also at least one triple bond, by definition it belongs to the alkynyl subgroup.
The above definition for alkynyl also applies if alkynyl is part of another group, as in Cx-y-alkynylamino or Cx-y-alkynyloxy, for example.
Unlike alkylene, alkynylene consists of at least two carbon atoms, wherein at least two adjacent carbon atoms are joined together by a C-C triple bond. If in an alkylene as hereinbefore defined having at least two carbon atoms, two hydrogen atoms in each case at adjacent carbon atoms are formally removed and the free valencies are saturated to form two further bonds, the corresponding alkynylene is formed.
Examples of alkynylene are ethynylene, propynylene, 1 -methylethynylene, butynylene, 1 -methylpropynylene, 1 ,1 -dimethylethynylene, 1 ,2-dimethylethynylene, pentynylene, 1 ,1 -dimethylpropynylene, 2,2-dimethylpropynylene, 1 ,2-dimethylpropynylene, 1 ,3-dimethylpropynylene, hexynylene etc.
By the generic terms propynylene, butynylene, pentynylene, hexynylene etc. without any further definition are meant all the conceivable isomeric forms with the corresponding number of carbon atoms, i.e. propynylene includes 1 -methylethynylene and butynylene includes 1 -methylpropynylene, 2-methylpropynylene, 1 ,1 -dimethylethynylene and 1 ,2- dimethylethynylene.
The above definition for alkynylene also applies if alkynylene is part of another group, as in HO-Cx-y-alkynyleneamino or H2N-Cx-y-alkynyleneoxy, for example.
By heteroatoms are meant oxygen, nitrogen and sulphur atoms.
Haloalkyl (haloalkenyl, haloalkynyl) is derived from the previously defined alkyl (alkenyl, alkynyl) by replacing one or more hydrogen atoms of the hydrocarbon chain independently of one another by halogen atoms, which may be identical or different. If a haloalkyl (haloalkenyl, haloalkynyl) is to be further substituted, the substitutions may take place independently of one another, in the form of mono- or polysubstitutions in each case, on all the hydrogen-carrying carbon atoms.
Examples of haloalkyl (haloalkenyl, haloalkynyl) are -CF3, -CHF2, -CH2F, -CF2CF3, -CHFCFs, -CH2CF3, -CF2CH3, -CHFCH3, -CF2CF2CF3, -CF2CH2CH3, -CF=CF2, -CCI=CH2, -CBr=CH2, -CI=CH2, -C≡C-CF3, -CHFCH2CH3, -CHFCH2CF3 etc.
From the previously defined haloalkyl (haloalkenyl, haloalkynyl) are also derived the terms haloalkylene (haloalkenylene, haloalkynylene). Haloalkylene (haloalkenyl, haloalkynyl), unlike haloalkyl, is bivalent and requires two binding partners. Formally, the second valency is formed by removing a hydrogen atom from a haloalkyl.
Corresponding groups are for example -CH2F and -CHF-, -CHFCH2F and -CHFCHF- or >CFCH2F etc.
The above definitions also apply if the corresponding halogen groups are part of another group.
Halogen relates to fluorine, chlorine, bromine and/or iodine atoms. Cycloalkyl is made up of the subgroups monocyclic hydrocarbon rings, bicyclic hydrocarbon rings and spiro-hydrocarbon rings. The systems are saturated. In bicyclic hydrocarbon rings two rings are joined together so that they have at least two carbon atoms together. In spiro-hydrocarbon rings a carbon atom (spiroatom) belongs to two rings together. If a cycloalkyl is to be substituted, the substitutions may take place independently of one another, in the form of mono- or polysubstitutions in each case, on all the hydrogen-carrying carbon atoms. Cycloalkyl itself may be linked as a substituent to the molecule via every suitable position of the ring system.
Examples of cycloalkyl are cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, bicyclo[2.2.0]hexyl , bicyclo[3.2.0]heptyl , bicyclo[3.2.1 ]octyl , bicyclo[2.2.2]octyl , bicyclo[4.3.0]nonyl (octahydroindenyl), bicyclo[4.4.0]decyl (decahydronaphthalene), bicyclo[2.2.1]heptyl (norbornyl), bicyclo[4.1 .0]heptyl (norcaranyl), bicyclo-[3.1.1 ]heptyl (pinanyl), spiro[2.5]octyl, spiro[3.3]heptyl etc.
The above definition for cycloalkyl also applies if cycloalkyl is part of another group as in Cx-y-cycloalkylamino or Cx-y-cycloalkyloxy, for example.
If the free valency of a cycloalkyl is saturated, then an alicyclic group is obtained.
The term cycloalkylene can thus be derived from the previously defined cycloalkyl. Cycloalkylene, unlike cycloalkyl, is bivalent and requires two binding partners. Formally, the second valency is obtained by removing a hydrogen atom from a cycloalkyl. Corresponding groups are for ex cyclohexyl and
Figure imgf000031_0001
(cyclohexylene).
The above definition for cycloalkylene also applies if cycloalkylene is part of another group as in HO-Cx-y-cycloalkyleneamino or H2N-Cx-y-cycloalkyleneoxy, for example.
Cycloalkenyl is also made up of the subgroups monocyclic hydrocarbon rings, bicyclic hydrocarbon rings and spiro-hydrocarbon rings. However, the systems are unsaturated, i.e. there is at least one C-C double bond but no aromatic system. If in a cycloalkyl as hereinbefore defined two hydrogen atoms at adjacent cyclic carbon atoms are formally removed and the free valencies are saturated to form a second bond, the corresponding cycloalkenyl is obtained. If a cycloalkenyl is to be substituted, the substitutions may take place independently of one another, in the form of mono- or polysubstitutions in each case, on all the hydrogen-carrying carbon atoms. Cycloalkenyl itself may be linked as a substituent to the molecule via every suitable position of the ring system.
Examples of cycloalkenyl are cycloprop-1 -enyl, cycloprop-2-enyl, cyclobut-1 -enyl, cyclobut-2-enyl, cyclopent-1 -enyl, cyclopent-2-enyl, cyclopent-3-enyl, cyclohex-1 -enyl, cyclohex-2-enyl, cyclohex-3-enyl, cyclohept-1 -enyl, cyclohept-2-enyl, cyclohept-3-enyl, cyclohept-4-enyl, cyclobuta-1 ,3-dienyl, cyclopenta-1 ,4-dienyl, cyclopenta-1 ,3-dienyl, cyclopenta-2,4-dienyl, cyclohexa-1 ,3-dienyl, cyclohexa-1 ,5-dienyl, cyclohexa-2,4-dienyl, cyclohexa-1 ,4-dienyl, cyclohexa-2,5-dienyl, bicyclo[2.2.1 ]hepta-2,5-dienyl
(norborna-2,5-dienyl), bicyclo[2.2.1 ]hept-2-enyl (norbornenyl), spiro[4.5]dec-2-ene etc.
The above definition for cycloalkenyl also applies when cycloalkenyl is part of another group as in Cx-y-cycloalkenylamino or Cx-y-cycloalkenyloxy, for example.
If the free valency of a cycloalkenyl is saturated, then an unsaturated alicyclic group is obtained.
The term cycloalkenylene can thus be derived from the previously defined cycloalkenyl. Cycloalkenylene, unlike cycloalkenyl, is bivalent and requires two binding partners. Formally the second valency is obtained by removing a hydrogen atom from a cycloalkenyl. Corresponding groups are for example cyclopentenyl and or J or *^ or *^ (cyclopentenylene) etc.
The above definition for cycloalkenylene also applies when cycloalkenylene is part of another group as in HO-Cx-y-cycloalkenyleneamino or H2N-Cx-y-cycloalkenyleneoxy, for example.
Aryl denotes a mono-, bi- or tricyclic group with at least one aromatic carbocycle. Preferably it denotes a monocyclic group with six carbon atoms (phenyl) or a bicyclic group with nine or ten carbon atoms (two six-membered rings or one six-membered ring with a five-membered ring), wherein the second ring may also be aromatic or, however, may also be saturated or partially saturated. If an aryl is to be substituted, the substitutions may take place independently of one another, in the form of mono- or polysubstitutions in each case, on all the hydrogen-carrying carbon atoms. Aryl itself may be linked as a substituent to the molecule via every suitable position of the ring system.
Examples of aryl are phenyl, naphthyl, indanyl (2,3-dihydroindenyl), indenyl, anthracenyl, phenanthrenyl, tetrahydronaphthyl (1 ,2,3,4-tetrahydronaphthyl, tetralinyl), dihydronaphthyl (1 ,2- dihydronaphthyl), fluorenyl etc. The above definition of aryl also applies when aryl is part of another group as in arylamino or aryloxy, for example.
If the free valency of an aryl is saturated, then an aromatic group is obtained.
The term arylene can also be derived from the previously defined aryl. Arylene, unlike aryl, is bivalent and requires two binding partners. Formally, the second valency is formed by removing a hydrogen atom from an aryl. Corresponding groups are e.g.
Figure imgf000033_0001
The above definition for arylene also applies when arylene is part of another group as in HO-aryleneamino or H2N-aryleneoxy for example.
Heterocyclyl denotes ring systems, which are derived from the previously defined cycloalkyl, cycloalkenyl and aryl by replacing one or more of the groups -CH2- independently of one another in the hydrocarbon rings by the groups -0-, -S- or -NH- or by replacing one or more of the groups =CH- by the group =N-, wherein a total of not more than five heteroatoms may be present, at least one carbon atom may be present between two oxygen atoms and between two sulphur atoms or between one oxygen and one sulphur atom and the ring as a whole must have chemical stability. Heteroatoms may optionally be present in all the possible oxidation stages (sulphur -> sulphoxide -SO, sulphone -S02-; nitrogen -> N-oxide). In a heterocyclyl there is no heteroaromatic ring, i.e. no heteratom is part of an aromatic system.
A direct result of the derivation from cycloalkyl, cycloalkenyl and aryl is that heterocyclyl is made up of the subgroups monocyclic heterorings, bicyclic heterorings, tricyclic heterorings and spiro-heterorings, which may be present in saturated or unsaturated form. By unsaturated is meant that there is at least one double bond in the ring system in question, but no heteroaromatic system is formed. In bicyclic heterorings two rings are linked together so that they have at least two (hetero)atoms in common. In spiro-heterorings a carbon atom (spiroatom) belongs to two rings together. If a heterocyclyl is substituted, the substitutions may take place independently of one another, in the form of mono- or polysubstitutions in each case, on all the hydrogen- carrying carbon and/or nitrogen atoms. Heterocyclyl itself may be linked as a substituent to the molecule via every suitable position of the ring system.
Examples of heterocyclyl are tetrahydrofuryl, pyrrolidinyl, pyrrolinyl, imidazolidinyl, thiazolidinyl, imidazolinyl, pyrazolidinyl, pyrazolinyl, piperidinyl, piperazinyl, oxiranyl, aziridinyl, azetidinyl, 1 ,4-dioxanyl, azepanyl, diazepanyl, morpholinyl, thiomorpholinyl, h om om orph ol i nyl , h omopi peri d i nyl , h om opi perazi nyl , h omoth i om orph ol i nyl , thiomorpholinyl-S-oxide, thiomorpholinyl-S,S-dioxide, 1 ,3-dioxolanyl, tetrahydropyranyl, tetrahydrothiopyranyl, [1 ,4]-oxazepanyl, tetrahydrothienyl, homothiomorpholinyl-S,S-dioxide, oxazolidinonyl, dihydropyrazolyl, dihydropyrrolyl , dihydropyrazinyl, dihydropyridyl, dihydro-pyrimidinyl, dihydrofuryl, dihydropyranyl, tetrahydrothienyl-S-oxide, tetrahydrothienyl-S,S-dioxide, homothiomorpholinyl-S-oxide,
2.3- dihydroazet, 2H-pyrrolyl, 4/-/-pyranyl, 1 ,4-dihydropyridinyl, 8-azabicyclo[3.2.1 ]octyl, 8-azabicyclo[5.1 .0]octyl, 2-oxa-5-azabicyclo[2.2.1]heptyl, 8-oxa-3-aza-bicyclo[3.2.1 ]octyl, 3,8-diaza-bicyclo[3.2.1]octyl, 2,5-diaza-bicyclo-[2.2.1 ]heptyl, 1 -aza-bicyclo[2.2.2]octyl, 3,8-diaza-bicyclo[3.2.1]octyl, 3,9-diaza-bicyclo[4.2.1]nonyl, 2,6-diaza-bicyclo[3.2.2]nonyl,
1 .4- dioxa-spiro[4.5]decyl, 1 -oxa-3.8-diaza-spiro[4.5]decyl, 2,6-diaza-spiro[3.3]heptyl,

The above definition of heterocyclyl also applies if heterocyclyl is part of another group as in heterocyclylamino or heterocyclyloxy for example.
If the free valency of a heterocyclyl is saturated, then a heterocyclic group is obtained.
The term heterocyclylene is also derived from the previously defined heterocyclyl. Heterocyclylene, unlike heterocyclyl, is bivalent and requires two binding partners. Formally, the second valency is obtained by removing a hydrogen atom from a heterocyclyl. Corresponding groups are for example piperidinyl and or or

The above definition of heterocyclylene also applies if heterocyclylene is part of another group as in HO-heterocyclyleneamino or H2N-heterocyclyleneoxy for example.
Heteroaryl denotes monocyclic heteroaromatic rings or polycyclic rings with at least one heteroaromatic ring, which compared with the corresponding aryl or cycloalkyl (cycloalkenyl) contain, instead of one or more carbon atoms, one or more identical or different heteroatoms, selected independently of one another from among nitrogen, sulphur and oxygen, wherein the resulting group must be chemically stable. The prerequisite for the presence of heteroaryl is a heteroatom and a heteroaromatic system. If a heteroaryl is to be substituted, the substitutions may take place independently of one another, in the form of mono- or polysubstitutions in each case, on all the hydrogen- carrying carbon and/or nitrogen atoms. Heteroaryl itself may be linked as a substituent to the molecule via every suitable position of the ring system, both carbon and nitrogen.
Examples of heteroaryl are furyl, thienyl, pyrrolyl, oxazolyl, thiazolyl, isoxazolyl, isothiazolyl, pyrazolyl, imidazolyl, triazolyl, tetrazolyl, oxadiazolyl, thiadiazolyl, pyridyl, pyrimidyl, pyridazinyl, pyrazinyl, triazinyl, pyridyl-/V-oxide, pyrrolyl-/V-oxide, pyrimidinyl-A- oxide, pyridazinyl-/V-oxide, pyrazinyl-/V-oxide, imidazolyl-/V-oxide, isoxazolyl-/V-oxide, oxazolyl-/V-oxide, thiazolyl-/V-oxide, oxadiazolyl-/V-oxide, thiadiazolyl-/V-oxide, triazolyl-/V- oxide, tetrazolyl-/V-oxide, indolyl, isoindolyl, benzofuryl, benzothienyl, benzoxazolyl, benzothiazolyl, benzisoxazolyl, benzisothiazolyl, benzimidazolyl, indazolyl, isoquinolinyl, quinolinyl, quinoxalinyl, cinnolinyl, phthalazinyl, quinazolinyl, benzotriazinyl, indolizinyl, oxazolopyridyl, imidazopyridyl, naphthyridinyl, benzoxazolyl, pyridopyridyl, purinyl, pteridinyl, benzothiazolyl, imidazopyridyl, imidazothiazolyl, quinolinyl-/V-oxide, indolyl-/V- oxide, isoquinolyl-/V-oxide, quinazolinyl-/V-oxide, quinoxalinyl-/V-oxide, phthalazinyl-/V- oxide, indolizinyl-/V-oxide, indazolyl-/V-oxide, benzothiazolyl-/V-oxide, benzimidazolyl-/V- oxide etc.
Further examples are the structures illustrated below, which may be attached via each hydrogen-carrying atom (exchanged for hydrogen):

Figure imgf000039_0001
The above definition of heteroaryl also applies when heteroaryl is part of another group as in heteroarylamino or heteroaryloxy, for example.
If the free valency of a heteroaryl is saturated, a heteroaromatic group is obtained.
The term heteroarylene can therefore be derived from the previously defined heteroaryl. Heteroarylene, unlike heteroaryl, is bivalent and requires two binding partners. Formally, the second valency is obtained by removing a hydrogen atom from a heteroaryl. Corresponding groups are for ex pyrrolyl and
Figure imgf000039_0002
or or or etc. The above definition of heteroarylene also applies when heteroarylene is part of another group as in HO-heteroaryleneamino or H2N-heteroaryleneoxy, for example.
By substituted is meant that a hydrogen atom which is bound directly to the atom under consideration, is replaced by another atom or another group of atoms (substituent). Depending on the starting conditions (number of hydrogen atoms) mono- or polysubstitution may take place on one atom. Substitution with a particular substituent is only possible if the permitted valencies of the substituent and of the atom that is to be substituted correspond to one another and the substitution leads to a stable compound (i .e. to a compound which is not converted spontaneously, e.g. by rearrangement, cyclisation or elimination).
Bivalent substituents such as =S, =NR, =NOR, =NNRR, =NN(R)C(0)NRR, =N2 or the like, may only be substituents at carbon atoms, wherein the bivalent substituent =0 may also be a substituent at sulphur. Generally, substitution may be carried out by a bivalent substituent only at ring systems and requires replacement by two geminal hydrogen atoms, i.e. hydrogen atoms that are bound to the same carbon atom that is saturated prior to the substitution. Substitution by a bivalent substituent is therefore only possible at the group -CH2- or sulphur atoms of a ring system.
Stereochemistry/Solvates/Hydrates: Unless stated otherwise a structural formula given in the description or in the claims or a chemical name refers to the corresponding compound itself, but also encompasses the tautomers, stereoisomers, optical and geometric isomers (e.g. enantiomers, diastereomers, EIZ isomers, etc.), racemates, mixtures of separate enantiomers in any desired combinations, mixtures of diastereomers, mixtures of the forms mentioned hereinbefore (if such forms exist) as well as salts, particularly pharmaceutically acceptable salts thereof. The compounds and salts according to the invention may be present in solvated form (e.g. with pharmaceutically acceptable solvents such as e.g. water, ethanol etc.) or in unsolvated form. Generally, for the purposes of the present invention the solvated forms, e.g. hydrates, are to be regarded as of equal value to the unsolvated forms.
Salts: The term "pharmaceutically acceptable" is used herein to denote compounds, materials, compositions and/or formulations which are suitable, according to generally recognised medical opinion, for use in conjunction with human and/or animal tissue and do not have or give rise to any excessive toxicity, irritation or immune response or lead to other problems or complications, i.e. correspond overall to an acceptable risk/benefit ratio.
The term "pharmaceutically acceptable salts" relates to derivatives of the chemical compounds disclosed in which the parent compound is modified by the addition of acid or base. Examples of pharmaceutically acceptable salts include (without being restricted thereto) salts of mineral or organic acids in relation to basic functional groups such as for example amines, alkali metal or organic salts of acid functional groups such as for example carboxylic acids, etc. These salts include in particular acetate, ascorbate, benzenesulphonate, benzoate, besylate, bicarbonate, bitartrate, bromide/hydrobromide, Ca-edetate/edetate, camsylate, carbonate, chloride/hydrochloride, citrate, edisylate, ethane disulphonate, estolate, esylate, fumarate, gluceptate, gluconate, glutamate, glycolate, glycollylarsnilate, hexylresorcinate, hydrabamine, hydroxymaleate, hydroxynaphthoate, iodide, isothionate, lactate, lactobionate, malate, maleate, mandelate, methanesulphonate, mesylate, methylbromide, methylnitrate, methylsulphate, mucate, napsylate, nitrate, oxalate, pamoate, pantothenate, phenyl acetate, phosphate/diphosphate, polygalacturonate, propionate, salicylate, stearate, subacetate, succinate, su lpham ide, su lphate, tan nate, tartrate, teoclate, tol uenesu lphonate, triethiodide, ammonium, benzathine, chloroprocaine, choline, diethanolamine, ethylenediamine, meglumin and procaine.

Pharm. Sci., (1977), 66, 1 -19).
The pharmaceutically acceptable salts of the present invention may be prepared starting from the parent compound which carries a basic or acidic functionality, by conventional chemical methods. Generally, such salts may be synthesised by reacting the free acid or base form of these compounds with a sufficient amount of the corresponding base or acid in water or an organic solvent such as for example ether, ethyl acetate, ethanol, isopropanol, acetonitrile (or mixtures thereof).
Salts of acids other than those mentioned above, which are useful for example for purifying or isolating the compounds from the reaction mixtures (e.g. trifluoroacetates), are also to be regarded as part of the invention.
In a representation such as for example
Figure imgf000042_0001
the letter A has the function of a ring designation in order to make it easier, for example, to indicate the attachment of the ring in question to other rings.
For bivalent groups in which it is crucial to determine which adjacent groups they bind and with which valency, the corresponding binding partners are indicated in brackets, where necessary for clarification purposes, as in the following representations:
Figure imgf000042_0002
or (R2)-C(0)NH- or (R2)-NHC(0)-;
Groups or substituents are frequently selected from among a number of alternative groups/ substituents with a corresponding group designation (e.g. Ra, Rb etc). If such a group is used repeatedly to define a compound according to the invention in different molecular parts, it must always be borne in mind that the various uses are to be regarded as totally independent of one another.
By a therapeutically effective amount for the purposes of this invention is meant a quantity of substance that is capable of obviating symptoms of illness or of preventing or alleviating these symptoms, or which prolong the survival of a treated patient.

Features and advantage of the present invention will become apparent from the following detailed Examples, which illustrate the fundamentals of the invention by way of example, without restricting its scope: Preparation of the compounds according to the invention
General
Unless stated otherwise, all the reactions are carried out in commercially obtainable apparatus using methods that are commonly used in chemical laboratories. Starting materials that are sensitive to air and/or moisture are stored under protective gas and corresponding reactions and manipulations therewith are carried out under protective gas (nitrogen or argon).
The compounds are named according to the Beilstein rules using the Autonom software (Beilstein). If a compound is to be represented both by a structural formula and by its nomenclature, in the event of a conflict the structural formula is decisive.
Microwave reactions are carried out in an initiator/reactor made by Biotage or in an Explorer made by CEM in sealed containers (preferably 2, 5 or 20 ml_), preferably with stirring.
Chromatography
Thin layer chromatography is carried out on ready-made TLC plates of silica gel 60 on glass (with fluorescence indicator F-254) made by Merck.
The preparative high pressure chromatography (HPLC) of the example compounds according to the invention is carried out with columns made by Waters (names: Sunfire C1 8, 5 m, 30 x 100 mm Part. No. 186002572; X-Bridge C18, 5 [Ji m , 30 x 100 mm Part. No. 186002982).

For chromatography under basic conditions H20/acetonitrile gradients are also used, and the water is made basic according to the following recipe: 5 mL of an ammonium hydrogen carbonate solution (158 g to 1 L H20) and 2 mL ammonia (7M in MeOH) are made up to 1 L with H20.
The normal-phase preparative high pressure chromatography (HPLC) of the example compounds according to the invention is carried out with colu mns made by Macherey & Nagel (name: Nucleosil, 50-7, 40 x 250 mm) and VDSoptilab (name: Kromasil 100 NH2, 10 μ Μ , 50 x 250 mm). The compounds are eluted using different gradients of DCIW MeOH, with 0.1 % NH3 added to the MeOH.
The analytical HPLC (reaction monitoring) of intermediate compounds is carried out with columns made by Agilent, Waters and Phenomenex. The analytical equipment is also provided with a mass detector in each case.
HPLC mass spectroscopy/UV spectrometry
The retention times/MS-ESI+ for characterising the example compounds according to the invention are produced using an HPLC-MS apparatus (high performance liquid chromatography with mass detector) made by Agilent.

The compounds according to the invention are prepared by the methods of synthesis described hereinafter, in which the substituents of the general formulae have the meanings given hereinbefore. These methods are intended as an illustration of the invention, without restricting its subject matter and the scope of the compounds claimed to these examples. Where the preparation of starting compounds is not described, they are commercially obtainable or may be prepared analogously to known compounds or methods described herein. Substances described in the literature are prepared according to the published methods of synthesis.
a) Synthesis of free cyclic carboxylic acids A
Reaction scheme A
Figure imgf000053_0001
A.d
The method of synthesising the nitrogen-containing heterocyclic carboxylic acids A depends on the number and position of the cyclic nitrogens in the ring Qb.
Starting from the esters A.a the grouping Qa-CR1R2- may be incorporated by nucleophilic substitution at the component A.b, which is activated by an electron-withdrawing leaving group LG, e.g. a halogen, triflate or mesylate. A.a is optionally deprotonated for this purpose by the addition of a base.
A pyridazinone ring system (Qb = pyridazinone) is synthesised starting from pyruvic acid derivatives which are cyclised with cyanoacetohydrazides. Subsequent saponification of the nitrile yields the corresponding carboxylic acid (Helv. Chim. Acta, 1954, 37, 1467), which after esterification yields the desired pyridazinonecarboxylic acid ester A.a. This is reacted in a nucleophilic substitution with A.b and subsequently saponified to form the desired carboxylic acid A.
A pyrimidinone ring system (Qb = pyrimidinone) is synthesised by cyclisation of malonic acid diester derivatives with amidines. The pyrimidinonecarboxylic acid ester A.a obtained is reacted in a nucleophilic substitution with A.b and subsequently saponified to form the desired carboxylic acid A (WO 2010/0071 14, WO 2010/0071 16).
A pyridinone ring system (Qb = pyridinone) is synthesised starting from malonic acid - diester derivatives A.d. The derivatives used are di- and trielectrophiles, which cyclise when reacted with amines A.c (WO 2010/0071 14, WO 2010/0071 16).
A pyrazinone ring system (Qb = pyrazinone) is synthesised starting from glyoxal derivatives and aminomalonamide amidines. First of all the corresponding amino- pyrazinecarboxamides are obtained, which are saponified to form the carboxylic acid. After hydrolysis of the amine by diazotisation and esterification of the carboxylic acid the desired pyrazinone ring system A.a is obtained (J. Am. Chem. Soc, 1959, 81, 2472-4). This is reacted in a nucleophilic substitution with A.b and then saponified to form the desired carboxylic acid A.
A pyrazolone ring system (Qb = pyrazolone) is obtained starting from malonic acid diester derivatives A.d, which cyclise with hydrazines A.e. The group LG is not a leaving group in the true sense but an electrophilic group, particularly a carbonyl, to which the hydrazine is added.
Using the methods of synthesis described above, starting from the cyclic carboxylic acid esters A.a or their precursors A.d after reaction with A.b or A.c, first of all carboxylic acid esters A* are obtained. These are each saponified to form the free acid A. In the grouping -COOR" , it is possible to have groups R" which make this saponification easy and gentle. Such groups include in particular methyl, ethyl, ie f-butyl and benzyl esters, wherein others are known to the skilled man from their general specialist knowledge.
The required educts A.b, A.c and A.e, as well as A.a and A.d, are commercially obtainable, already described in the literature or may be prepared analogously to published methods. ethod for synthesising A.1

Reaction scheme B
Figure imgf000069_0002
The amides C required are synthesised by coupling a propargylamine B with the carboxylic acid A. The amide coupling is assisted by coupling reagents such as for example DCC, DIC, TBTU, HATU, EDC or the like, or the formation of the corresponding acid chloride.
The synthesis components which are to be used in the above reaction schemes are optionally provided with common protective groups when used. Therefore, additional intermediate steps may be needed to eliminate these protective groups.
With regard to the feasibility of the reaction methods illustrated and described in the above reaction schemes reference is made to WO 2008/005457. In the cited specification, pyridinonecarboxylic acids A are amidated in a variety of ways. Method of synthesising C.1

The ring systems QH of compounds according to the invention, i.e. embodiments QH-2a to QH-2f, can be incorporated in the target structures by various methods. Starting from bisfunctional components D*, which are activated by an electron-withdrawing group EWG, particularly chlorine, bromine or iodine, and a further group which enables the substituents R5, R6, R7 and R8 to be inserted in their respective positions, first of all the substituent R5, R6, R7 or R8 can be introduced and in this way the component D is obtained (QH* -> QH). D is then reacted in a SONOGASHIRA reaction with C to form the compound according to the invention (1 ) (cf. also reaction scheme D). In an alternative sequence first D* may be reacted with C in the SONOGASHIRA reaction and only then is the substituent R5, R6, R7 or R8 introduced (cf. also reaction scheme F). The position of the group EWG on the ring system QH/QH* denotes the linkage point of the ring system to the linker unit, i.e. in this case to the C-C triple bond.
As another alternative it is possible to carry out the SONOGASHIRA reaction between N-protected propargylamines B and D* or D and couple the intermediates R4-NH-L-QH or R4-NH-L-QH* obtained with the acids A (cf. this method of inserting alkenyl linkers, reaction schemes G and H). The final substituents R5, R6, R7 or R8 (QH -> QH*) are introduced for example by nucleophilic substitution, SUZUKI coupling, amidation (optionally activation with DCC, DIC, TBTU, HATU, EDC or the like), reductive alkylation or, however, during the ring formation of the corresponding system QH. Other possibilities are BUCHWALD-HARTWIG, NEGISHI , HECK or SONOGASHIRA reactions. The activating groups that are suitable for these reactions are well known in the art.
The synthesis of bisfunctional components D*which are suitable for incorporating the ring systems QH in compounds (1 ) according to the invention, is described in the literature. They may be prepared using published methods or can be directly obtained commercially: QH-2b: e.g. Tetrahedron Lett. 2002, 6209; WO 2007/133637;

The following Examples describe the biological activity of the compounds according to the invention, without restricting the invention to these Examples.
Compounds of general formula (1 ) are characterised by their many possible applications in the therapeutic field. Particular mention should be made of those applications in which the inhibition of specific signal enzymes, particularly the inhibiting effect on the proliferation of cultivated human tumour cells but also on the proliferation of other cells such as endothelial cells, for example, are involved. The activity of the compounds according to the invention on the kinase PDK1 which inhibits the signal transduction pathway is determined in an in vitro kinase assay with recombinantly prepared protein:
PDK1 Kinase Assay
Recombinant human PDK1 enzyme (aa 52-556) linked at its N-terminal end to His6 is isolated from baculovirus-infected insect cells. Purified enzyme may be obtained for example from the University of Dundee, Scotland. The following components are combined in a well of a 96-well round-based dish (Greiner bio-one, No. 650101 ):

15 μΙ_ His6-PDK1 (aa 52-556) 3.33 ng/well) and PDKtide
(KTFCGTPEYLAPEVRRE PRILSEEEQEMFRDFDYIADWC), synthesised by Pepceuticals Limited, Nottingham, United Kingdom; 25 μΜ final concentration); His6-PDK1 and PDKtide are together diluted accordingly in assay buffer (50 mM tris pH 7.5, 0.05 % β-mercaptoethanol, 10 mM Mg-acetate); PDKtide is present in this mixture as an 83.3 μΜ solution. These 30 μΙ are routinely incubated for 30 min at RT.
• 20 μΙ_ ATP solution (25 μΜ ATP with 1.0 μΟί/ννβΙΙ gamma-P33-ATP). The final concentration of Tween 20 is 0.005%.
The reaction is started by adding the ATP solution and the mixture is incubated for 90 min at RT. At the start of the reaction the dishes are shaken gently. The reaction is stopped by the addition of 50 μ-Jwell of 500 mM phosphoric acid (H3P04) and incubated for about 20 min at RT. The precipitate is transferred by harvesting onto filter plates (96-well microtitre filter plate: UniFilter GF/C; Perkin Elmer; No. 6005174), then washed 6 times with 50 mM H3P04 and dried at 60°C. Then the plate is stuck down with sealing tape, 25 [\Uwe\\ of scintillation solution (Microscint 0; Perkin Elmer; No. 601361 1 ) are added and the amount of P33 precipitated is measured using the Wallac Betacounter. The measured data are evaluated using Graphpad Prism software.

The antiproliferative activity of the compounds according to the invention is determined in the proliferation test on cultivated human tumour cells and/or in a cell cycle analysis, for example on PC-3 tumour cells: Inhibition of proliferation on cultivated human tumour cells (PC-3)
To measure proliferation on prostate carcinoma tumour cell line PC-3 (obtained from American Type Culture Collection (ATCC)) the cells are cultivated in Ham's F12K (Gibco) and 10% foetal calf serum (Gibco) and harvested in the log growth phase. Then the PC-3 cells are placed in 96-well plates (Costar) at a density of 2000 cells per well and incubated overnight in an incubator (at 37°C and 5 % C02), wherein on each plate 16 wells are used as controls [8 wells with cells to which only DMSO solution has been added (should yield 30 - 50% maximum value of reduced AlamarBlue), 4 wells containing only medium (medium control, after the addition of oxidised AlamarBlue reagent the background signal is obtained) and 4 wells where again only medium is added (after the addition of reduced AlamarBlue reagent it acts as a maximum value)]. The active substances are added to the cells in various concentrations (dissolved in DMSO; DMSO final concentration: 0.2%) (in each case as a double or triple measurement). After 5 d incubation 20 μΙ AlamarBlue reagent (Serotec) are added to each well, and the cells are incubated for a further 5-7 h. As a control, 20 μΙ reduced AlamarBlue reagent is added to each of 4 wells (AlamarBlue reagent which is autoclaved for 30 min). After incubation the colour change of the AlamarBlue reagent in the individual wells is determined in a SpectraMax Photometer (Molecular Devices) (extinction 530 nm, emission 590 nm, 5 s measuring time). The amount of AlamarBlue reagent reacted represents the metabolic activity of the cells. The relative cell activity is calculated in relation to the control (PC-3 cells without inhibitor) and the active substance concentration which inhibits the cell activity by 50% (EC50) is derived. The values are calculated from the average of two or three individual measurements.
Many of the compounds according to the invention cause inhibition of proliferation by interfering with intracellular signal transduction pathways which are important for cell survival, predominantly, but not exclusively, in cells which have become dependent on these signal pathways during their development.
Compounds (1 ) according to the invention generally demonstrate good activity in cell assays of this kind, i.e. for example an EC50 value in the PC-3 proliferation test of less than 10 μη"ΐοΙ/Ι_, often less than 5 μmol L.
Biomarker inhibition:
The substances of the present invention bring about cellular inhibition of PDK1 -substrates. Examples of the latter are Phospho-Thr308/AKT, Phospho-Ser221 ,227/RSK, or phosphorylation sites on p70S6 kinase (Thr229). In order to determine the inhibitory effect, the cells are treated with substance for 2 h, for example, lysed and analysed by Western Blot and/or BioPlex analysis for phosphoproteins of this kind. Commercially obtainable phospho-specific antibodies to the above-mentioned phosphorylation sites are used.
In PC-3 or other signal pathway-mutated cell lines as a rule EC50 values of less than 5 μη"ΐοΙ/Ι_, often less than 0.5 μη"ΐοΙ/Ι_, are achieved with the present compounds on these phosphorylation sites compared with the carrier control and after standardisation to the corresponding whole protein. On the basis of their biological properties the compounds of general formula (1 ) according to the invention, their tautomers, racemates, enantiomers, diastereomers, mixtures thereof and the salts of all the above-mentioned forms are suitable for treating diseases characterised by excessive or abnormal cell proliferation or by aberrant activation of the phosphatidylinositol-3-kinase (PI3K)-PDK1 -AKT signal pathway.

Suitable preparations include for example tablets, capsules, suppositories, solutions - particularly solutions for injection (s.c, i.v., i.m.) and infusion - elixirs, emulsions or dispersible powders. The content of the pharmaceutically active compound(s) should be in the range from 0.1 to 90 wt.-%, preferably 0.5 to 50 wt.-% of the composition as a whole, i.e. in amounts which are sufficient to achieve the dosage range specified below. The doses specified may, if necessary, be given several times a day.
Suitable tablets may be obtained, for example, by mixing the active substance(s) with known excipients, for example inert diluents such as calcium carbonate, calcium phosphate or lactose, disintegrants such as corn starch or alginic acid, binders such as starch or gelatine, lubricants such as magnesium stearate or talc and/or agents for delaying release, such as carboxymethyl cellulose, cellulose acetate phthalate, or polyvinyl acetate. The tablets may also comprise several layers. Coated tablets may be prepared accordingly by coating cores produced analogously to the tablets with substances normally used for tablet coatings, for example collidone or shellac, gum arabic, talc, titanium dioxide or sugar. To achieve delayed release or prevent incompatibilities the core may also consist of a number of layers. Similarly the tablet coating may consist of a number of layers to achieve delayed release, possibly using the excipients mentioned above for the tablets.
Syrups or elixirs containing the active substances or combinations thereof according to the invention may additionally contain a sweetener such as saccharine, cyclamate, glycerol or sugar and a flavour enhancer, e.g. a flavouring such as vanillin or orange extract. They may also contain suspension adjuvants or thickeners such as sodium carboxymethyl cellulose, wetting agents such as, for example, condensation products of fatty alcohols with ethylene oxide, or preservatives such as p-hydroxybenzoates.
Solutions for injection and infusion are prepared in the usual way, e.g. with the addition of isotonic agents, preservatives such as p-hydroxybenzoates, or stabilisers such as alkali metal salts of ethylenediamine tetraacetic acid , optionally using emulsifiers and/or dispersants, whilst if water is used as the diluent, for example, organic solvents may optionally be used as solvating agents or dissolving aids, and transferred into injection vials or ampoules or infusion bottles. Capsules containing one or more active substances or combinations of active substances may for example be prepared by mixing the active substances with inert carriers such as lactose or sorbitol and packing them into gelatine capsules.
Suitable suppositories may be made for example by mixing with carriers provided for this purpose, such as neutral fats or polyethyleneglycol or the derivatives thereof.
Excipients which may be used include, for example, water, pharmaceutically acceptable organic solvents such as paraffins (e.g. petroleum fractions), vegetable oils (e.g. groundnut or sesame oil), mono- or polyfunctional alcohols (e.g. ethanol or glycerol), carriers such as e.g. natural mineral powders (e.g. kaolins, clays, talc, chalk), synthetic mineral powders (e.g. highly dispersed silicic acid and silicates), sugars (e.g. cane sugar, lactose and glucose) emulsifiers (e.g. lignin, spent sulphite liquors, methylcellulose, starch and polyvinylpyrrolidone) and lubricants (e.g. magnesium stearate, talc, stearic acid and sodium lauryl sulphate).
The preparations are administered by th e usu al m ethods , preferably by ora l or transdermal route, most preferably by oral route. For oral administration the tablets may, of course contain, apart from the abovementioned carriers, additives such as sodium citrate, calcium carbonate and dicalcium phosphate together with various additives such as starch, preferably potato starch, gelatine and the like. Moreover, lubricants such as magnesium stearate, sodium lauryl sulphate and talc may be used at the same time for the tabletting process. In the case of aqueous suspensions the active substances may be combined with various flavour enhancers or colourings in addition to the excipients mentioned above.
For parenteral use, solutions of the active substances with suitable liquid carriers may be used.
The dosage for intravenous use is from 1 - 1000 mg per hour, preferably between 5 and 500 mg per hour.
However, it may sometimes be necessary to depart from the amounts specified , depending on the body weight, the route of administration, the individual response to the drug, the nature of its formulation and the time or interval over which the drug is administered. Thus, in some cases it may be sufficient to use less than the minimum dose given above, whereas in other cases the upper limit may have to be exceeded. When administering large amounts it may be advisable to divide them up into a number of smaller doses spread over the day.
