The invention relates to imidazoquinolinones, salts and prodrugs thereof, processes for their preparation, their use in the treatment of protein or lipid kinase dependent diseases and in particular phosphatidylinositol-3-kinase (PI3K) dependent diseases, their use, either alone or in combination with at least one additional therapeutic agent and optionally in combination with a pharmaceutically acceptable carrier, for the manufacture of pharmaceutical preparations, use of the pharmaceutical preparations for the treatment of protein or lipid kinase dependant diseases and in particular PI3K dependent diseases, and a method of treatment of said diseases, comprising administering the imidazoquinolinones to a warm-blooded animal, especially a human. The invention also relates to pharmaceutical preparations comprising an imidazoquinolinone of the invention, either alone or in combination with at least one additional therapeutic agent, and optionally in combination with a pharmaceutically acceptable carrier.
The phosphatidylinositol-3-kinases superfamily comprises 4 different PI3K related lipid or protein kinases. Class I, II and III are lipid kinases that differ from their substrate specificities whereas class IV PI3K also called PI3-kinase-related protein kinase (PIKK) are protein kinases. Class I phosphatidylinositol-3-kinases comprise a family of lipid kinases that catalyze the transfer of phosphate to the D-3′ position of inositol lipids to produce phosphoinositol-3-phosphate (PIP), phosphoinositol-3,4-diphosphate (PIP2) and phosphoinositol-3,4,5-triphosphate (PIP3) that, in turn, act as second messengers in signaling cascades by docking proteins containing pleckstrin-homology, FYVE, Phox and other phospholipid-binding domains into a variety of signaling complexes often at the plasma membrane ((Vanhaesebroeck et al., Annu. Rev. Biochem 70:535 (2001); Katso et al., Annu. Rev. Cell Dev. Biol. 17:615 (2001)). Of the two Class I PI3Ks, Class IA PI3Ks are heterodimers composed of a catalytic p110 subunit (α, β, δ isoforms) constitutively associated with a regulatory subunit that can be p85α, p55α, p50α, p85β or p55γ. The Class IB sub-class has one family member, a heterodimer composed of a catalytic p110γ subunit associated with one of two regulatory subunits, p101 or p84 (Fruman et al., Annu Rev. Biochem. 67:481 (1998); Suire et al., Curr. Biol. 15:566 (2005)). The modular domains of the p85/55/50 subunits include Src Homology (SH2) domains that bind phosphotyrosine residues in a specific sequence context on activated receptor and cytoplasmic tyrosine kinases, resulting in activation and localization of Class IA PI3Ks. Class IB PI3K is activated directly by G protein-coupled receptors that bind a diverse repertoire of peptide and non-peptide ligands (Stephens et al., Cell 89:105 (1997)); Katso et al., Annu. Rev. Cell Dev. Biol. 17:615-675 (2001)). Consequently, the resultant phospholipid products of class I PI3K link upstream receptors with downstream cellular activities including proliferation, survival, chemotaxis, cellular trafficking, motility, metabolism, inflammatory and allergic responses, transcription and translation (Cantley et al., Cell 64:281 (1991); Escobedo and Williams, Nature 335:85 (1988); Fantl et al., Cell 69:413 (1992)).
In many cases, PIP2 and PIP3 recruit Akt, the product of the human homologue of the viral oncogene v-Akt, to the plasma membrane where it acts as a nodal point for many intracellular signaling pathways important for growth and survival (Fantl et al., Cell 69:413-423(1992); Bader et al., Nature Rev. Cancer 5:921 (2005); Vivanco and Sawyer, Nature Rev. Cancer 2:489 (2002)). Aberrant regulation of PI3K, which often increases survival through Akt activation, is one of the most prevalent events in human cancer and has been shown to occur at multiple levels. The tumor suppressor gene PTEN, which dephosphorylates phosphoinositides at the 3′ position of the inositol ring and in so doing antagonizes PI3K activity, is functionally deleted in a variety of tumors. In other tumors, the genes for the p110α, isoform, PIK3CA, and for Akt are amplified and increased protein expression of their gene products has been demonstrated in several human cancers. Furthermore, mutations and translocation of p85α that serve to up-regulate the p85-p110 complex have been described in human cancers. Also, somatic missense mutations in PIK3CA that activate downstream signaling pathways have been described at significant frequencies in a wide diversity of human cancers (Kang at al., Proc. Natl. Acad. Sci. USA 102:802 (2005); Samuels et al., Science 304:554 (2004); Samuels et al., Cancer Cell 7:561-573 (2005)). These observations show that deregulation of phosphoinositol-3 kinase and the upstream and downstream components of this signaling pathway is one of the most common deregulations associated with human cancers and proliferative diseases (Parsons et al., Nature 436:792 (2005); Hennessey at el., Nature Rev. Drug Disc. 4:988-1004 (2005)).
The mammalian target of rapamycin (mTOR) is a member of the class IV PI3K. mTOR assembles a signaling network that transduces nutrient signals and various other stimuli to regulate a wide range of cellular functions including cell growth, proliferation, survival, autophagy, various types of differentiation and metabolism. In mammalian cells, the mTOR protein is found complexed in two distinct entities called mTORC1 and mTORC2. The mTORC1 complex, that is to say mTOR associated with raptor, has been the matter of numerous studies. It is mTORC1 that integrates nutrient and growth factor input, and is in turn responsible for cell growth regulation, mainly through protein synthesis regulators such as 4EBP1 or RPS6. Activation of mTORC1 requires input from active PI3K and Akt kinases meaning that mTORC1 is a downstream effector of the PI3K pathway. mTOR when associated in the mTOR complex 2 (mTORC2) has been shown to be responsible for the activation of Akt by phosphorylation of S473 (Akt 1 numbering) (Sarbassov et al., Science 307: 7098 (2005)). mTORC2 is hence here considered as an upstream activator of Akt. Interestingly mTOR can therefore be considered as being important both upstream and downstream of Akt. Taken together, mTOR can be regarded as a downstream effector and an upstream activator of Aid depending on its association with the mTOCR1 and mTORC2 complex, respectively. mTOR catalytic inhibition might therefore represent a unique way of introducing a very strong block in the PI3K-Akt pathway, by addressing both upstream and downstream effectors. Syndromes with an established or potential molecular link to disregulation of mTOR kinase activity are, for instance, described in “K. Inoki et al.; Disregulation of the TSC-mTOR pathway in human disease, Nature Genetics, vol 37, 19-24”; “D. M. Sabatini; mTOR and cancer: insights into a complex relationship, Nature Reviews, vol. 6, 729-734”; and in “B. T. Hennessy et al.; Exploiting the PI3K/Akt pathway for cancer drug discovery, Nature Reviews, vol. 4, 988-1004”, and are as follows:
Compounds with an inhibitory activity on mTORC1 have shown benefit in immunomodulation and in treating proliferative diseases such as advance renal cell carcinoma or Tubero-Sclerosis (TSC) germ line mutation associated disorders.
The catalytic inhibition of mTOR Ser/Thr kinase activity or class I PI3 kinases activity and in particular dual class I PI3-kinase(s) and mTOR kinase inhibition is considered to be useful for the treatment of PI3K/Akt/mTOR pathway dependent diseases.
The efficacy of a dual PI3 kinase/mTOR inhibitor in malignant glioma has been recently described (Cancer Cell 9, 341-349).
In view of the above, inhibitors of class I and/or IV PI3Ks are considered to be of value in the treatment of proliferative disease and other disorders.
WO2003/097641, WO2005/054237, WO2005/054238 and WO2006/122806 describe imidazoquinolines for use in the treatment of protein kinase dependent diseases.
WO 2008/103636 describes imidazoquinolines as dual lipid kinase and mTor inhibitors.
It has now been found that the imidazoquinolinones derivatives of the formula (I) given below have advantageous pharmacological properties and inhibit, for example, lipid or protein kinases such as PI4K (phosphatidylinositol 4-kinase) and/or PI3 kinases (phosphatidylinositol 3-kinases), for example, inhibition of the PI3K superfamily which comprises PI3Kalpha, PI3Kbeta, PI3Kdelta, PI3Kgamma and mTOR, or one or more of the individual kinase members thereof. The class IV PI3K also called PI3-kinase-related protein kinase (PIKK) includes DNA-PK, ATM, ATR, hSMG-1 and mTOR. In particular, preferably imidazoquinolinones of the formula (I) given below show a high degree of selectivity in favour of one or more of the class I-IV P13K against other protein kinases, such as the receptor tyrosine kinases and/or the Ser/Thr kinases outside of the PIKK family in the biochemical and/or in the cellular assay. In addition, the imidazoquinolinones of the formula (I) preferably display a favourable solubility and/or membrane permeability at physiological pH. Hence, the compounds of formula (I) are suitable, for example, to be used in the treatment of diseases dependent on PI3 kinase, especially proliferative diseases such as tumor diseases, leukaemias, and myeloproliferative disorders such as polycythemia vera, essential thrombocythemia, and myelofibrosis with myeloid metaplasia, and proliferative skin diseases including basal cell carcinoma, squamous cell carcinoma and actinic keratosis and other benign hyperproliferative skin disorders caused by inflammation such as psoriasis or as a result of dysregulation of fibroblasts such as skin fibrosis, scleroderma or keloids.
In a first aspect, the present invention provides compounds of the formula (I)
wherein
The present invention is also directed to use of compounds of formula (I) in the treatment of protein and/or lipid kinase dependent diseases; use of compounds of formula (I) for the manufacture of pharmaceutical preparations for the treatment of protein and/or lipid kinase dependent diseases and in particular PI3K superfamily (especially class I PI3K and/or mTOR) dependent diseases; methods of treating protein and/or lipid kinase dependant diseases and in particular PI3K superfamily (especially class I PI3K and/or mTOR) dependent diseases comprising administering imidazoquinolinone compounds of the formula (I) to a warm-blooded animal, especially a human; pharmaceutical preparations comprising an imidazoquinolinone compound of the formula (I), especially for the treatment of a protein and/or lipid kinase dependant disease and in particular a PI3K superfamily (especially class I PI3K and/or mTOR) dependent disease; a process for the manufacture of the novel imidazoquinolinone compounds of the formula (I); the manufacture of a pharmaceutical preparation for the treatment of protein and/or lipid kinase dependant diseases and in particular PI3K superfamily (especially class I PI3K and/or mTOR) dependent diseases, and novel intermediates for their manufacture. Preferably, the PI3K superfamily dependent diseases are class I PI3K and/or mTOR dependent diseases.
The invention may be more fully appreciated by reference to the following description, including the following glossary of terms and the concluding examples. As used herein, the terms “including”, “containing” and “comprising” are used herein in their open, non-limiting sense.
Any formula given herein is intended to represent compounds having structures depicted by the structural formula as well as certain variations or forms. In particular, compounds of any formula given herein may have asymmetric centers and therefore exist in different stereoisomeric forms such as different enantiomeric forms. If at least one asymmetrical carbon atom is present in a compound of the formula I, such a compound may exist in optically active form or in the form of a mixture of optical isomers, e.g. in the form of a racemic mixture. Thus an asymmetric carbon atom may be present in the (R)-, (S)- or (R,S)-configuration, preferably in the (R)- or (S)-configuration. All optical isomers and their mixtures, including the racemic mixtures, are part of the present invention. Thus, any given formula given herein is intended to represent a racemate, one or more enantiomeric forms, one or more diastereomeric forms, one or more atropisomeric forms, and mixtures thereof. Furthermore, certain structures may exist as geometric isomers (e.g. cis and trans isomers), as tautomers, or as atropisomers. For example, substituents at a double bond or a ring may be present in cis-(=Z-) or trans (=E-) form. The compounds of the invention may thus be present as mixtures of isomers or preferably as pure isomers, preferably as enantiomer-pure diastereomers or pure enantiomers.
Any formula given herein is intended to represent hydrates, solvates, and polymorphs of such compounds, and mixtures thereof.
Any formula given herein is also intended to represent unlabeled forms as well as isotopically labeled forms of the compounds. Isotopically labeled compounds have structures depicted by the formulas given herein except that one or more atoms are replaced by an atom having a selected atomic mass or mass number. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine, and chlorine, such as 2H, 3H, 11C, 13C, 14C, 15N, 31P, 32P, 18F, 35S, 36Cl, 125I respectively. Various isotopically labeled compounds of the present invention, for example those into which radioactive isotopes such as 3H, 13C, and 14C are incorporated. Such isotopically labelled compounds are useful in metabolic studies (preferably with 14C), reaction kinetic studies (with, for example 2H or 3H), detection or imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT) including drug or substrate tissue distribution assays, or in radioactive treatment of patients. In particular, an 18F or labeled compound may be particularly preferred for PET or SPECT studies. Further, substitution with heavier isotopes such as deuterium (i.e., 2H) may afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements. Isotopically labeled compounds of this invention and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations described below by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent.
When referring to any formula given herein, the selection of a particular moiety from a list of possible species for a specified variable is not intended to define the moiety for the variable appearing elsewhere. In other words, where a variable appears more than once, the choice of the species from a specified list is independent of the choice of the species for the same variable elsewhere in the formula (where one or more up to all more general expressions in embodiments characterized as preferred above or below can be replaced with a more specific definition, thus leading to a more preferred embodiment of the invention, respectively).
Where the plural form (e.g. compounds, salts, pharmaceutical preparations, diseases and the like) is used, this includes the singular (e.g. a single compound, a single salt, a single pharmaceutical preparation, a single disease, and the like). “A compound” does not exclude that (e.g. in a pharmaceutical formulation) more than one compound of the formula (I) (or a salt thereof) is present.
Salts are preferably the pharmaceutically acceptable salts of compounds of formula (I) if they are carrying salt-forming groups.
The salts of compounds of formula (I) are preferably pharmaceutically acceptable salts; acids/bases required to form the salts are generally known in the field.
Salt-forming groups in a compound of formula (I) are groups or radicals having basic or acidic properties. Compounds having at least one basic group or at least one basic radical, e.g., amino; a secondary amino group not forming a peptide bond or a pyridyl radical, may form acid addition salts, e.g., with inorganic acids, such as hydrochloric acid, sulfuric acid or a phosphoric acid; or with suitable organic carboxylic or sulfonic acids, e.g., aliphatic mono- or di-carboxylic acids, such as trifluoroacetic acid, acetic acid, propionic acid, glycolic acid, succinic acid, maleic acid, fumaric acid, hydroxymaleic acid, malic acid, tartaric acid, citric acid or oxalic acid; or amino acids, such as arginine or lysine; aromatic carboxylic acids, such as benzoic acid; 2-phenoxy-benzoic acid; 2-acetoxy-benzoic acid; salicylic acid; 4-aminosalicylic acid; aromatic-aliphatic carboxylic acids, such as mandelic acid or cinnamic acid; heteroaromatic carboxylic acids, such as nicotinic acid or isonicotinic acid; aliphatic sulfonic acids, such as methane-, ethane- or 2-hydroxyethanesulfonic acid; or aromatic sulfonic acids, e.g., benzene-, p-toluene- or naphthalene-2-sulfonic acid. When several basic groups are present mono- or poly-acid addition salts may be formed.
Compounds of formula (I) having acidic groups, a carboxy group or a phenolic hydroxy group, may form metal or ammonium salts, such as alkali metal or alkaline earth metal salts, e.g., sodium, potassium, magnesium or calcium salts; or ammonium salts with ammonia or suitable organic amines, such as tertiary monoamines, e.g., triethylamine or tri(2-hydroxyethyl)-amine, or heterocyclic bases, e.g., N-ethyl-piperidine or N,N′-dimethylpiperazine. Mixtures of salts are possible.
Compounds of formula (I) having both acidic and basic groups can form internal salts.
For the purposes of isolation or purification, as well as in the case of compounds that are used further as intermediates, it is also possible to use pharmaceutically-unacceptable salts, e.g., the picrates. Only pharmaceutically-acceptable, non-toxic salts may be used for therapeutic purposes, however, and those salts are therefore preferred.
Owing to the close relationship between the novel compounds in free form and in the form of their salts, including those salts that can be used as intermediates, e.g., in the purification of the novel compounds or for the identification thereof, any reference hereinbefore and hereinafter to the free compounds shall be understood as including the corresponding salts, where appropriate and expedient.
Compounds of the present invention may also form solvates and hydrates, and as such any reference to a compound of formula (I) is therefore to be understood as referring also to the corresponding solvate and/or hydrate of the compound of formula (I), as appropriate and expedient.
The present invention also relates to pro-drugs of a compound of formula (I) that convert in vivo to the compound of formula (I) as such. Any reference to a compound of formula (I) is therefore to be understood as referring also to the corresponding pro-drugs of the compound of formula (I), as appropriate and expedient.

R1
As indicated hereinabove, R1 is a 5-membered heteroaryl having the appropriate corresponding meaning as for heteroaryl given above, with “5-membered” meaning that there are 5 ring atoms, one or more being a heteroatom, such as nitrogen, oxygen or sulfur. Such 5-membered heteroaryl groups include monocyclic rings, such as pyrazolyl, thienyl, furyl, pyrrolyl, thiazolyl, isothiazolyl, oxazolyl, isoxazolyl, oxadiazolyl, triazolyl, imidazolyl, tetrazolyl or thiadiazolyl, preferably pyrazolyl, each being unsubstituted or substituted, e.g. by the groups listed herein under “substituted”.
In an embodiment, R1 is pyrazolyl or isoxazolyl, each being unsubstituted or substituted, e.g. by the groups listed herein under “substituted”.
In an embodiment, R1 is unsubstituted or substituted pyrazolyl or unsubstituted or substituted isoxazolyl. Preferably the pyrazolyl is substituted, preferably by one, two or three substituents and the isoxazolyl is substituted, preferably by one or two substituents, wherein in each case, said substituents may for example be independently selected from halo, unsubstituted or substituted alkyl, unsubstituted or substituted alkenyl, unsubstituted or substituted alkynyl, unsubstituted or substituted lower alkoxy, unsubstituted or substituted lower alkylamino, unsubstituted or substituted alkoxy lower alkyl, unsubstituted or substituted cycloalkyl, unsubstituted or substituted cycloalkenyl, unsubstituted or substituted carbamoyl lower alkyl, lower mono- and di-alkyl carbamoyl lower alkyl, unsubstituted or substituted cycloaminocarbonyl lower alkyl, unsubstituted or substituted heterocyclylcarbonyl lower alkyl, unsubstituted or substituted hydroxyl lower alkyl, unsubstituted or substituted carboxy lower alkyl, halo-loweralkyl, hydroxycarbonyl-loweralkyl, morpholinecarbonylalkyl, hydroxy or amino.
In an embodiment, R1 is unsubstituted isoxazolyl.
In an embodiment, R1 is isoxazolyl substituted by one or two substituents selected from halo, lower alkyl, unsubstituted or substituted lower alkenyl, unsubstituted or substituted alkynyl, unsubstituted or substituted cycloalkyl, unsubstituted or substituted cycloalkenyl, unsubstituted or substituted lower alkoxy, substituted or unsubstituted lower alkyl amino, hydroxy or amino.

In an embodiment, R1 is isoxazolyl substituted by one or two substituents selected from unsubstituted lower alkyl, unsubstituted lower alkenyl, unsubstituted alkynyl, unsubstituted cycloloweralkyl, hydroxy or amino.
In an embodiment, R1 is isoxazolyl substituted by one or two, same or different, unsubstituted lower alkyl substituents (in particular C1-C4alkyl) such as methyl or ethyl, preferably methyl.
In an embodiment, when R1 is unsubstituted or substituted isoxazolyl, said isoxazolyl is isoxazol-3-yl, isoxazol-4-yl or isoxazol-5-yl.
It is preferred that a substituent of said substituted isoxazolyl is bonded to the isoxazolyl ring at the alpha position to the ring atom which bonds the isoxazolyl ring to the rest of the molecule (that is, the alpha position is at a position on the isoxazolyl ring which is next to the isoxazolyl ring atom which is bonded to the imidazoquinolinone part of the molecule). The isoxazolyl ring atom which is bonded to the rest of the molecule (i.e. the imidazoquinolinone part) is a carbon atom. Thus, preferred isoxazolyl groups are alpha-substituted isoxazolyl. For the avoidance of doubt the ring atom at the alpha position may be a carbon, nitrogen or oxygen ring atom, with at least one atom in the alpha position being a carbon atom, but, for chemical valency reasons, only an alpha carbon atom may be substituted.
An embodiment of the invention includes compounds of formula (I) wherein R1 is unsubstituted or substituted isoxazol-4-yl, thus R1 in this embodiment is represented by a group of formula (AB):
wherein, the curved line indicates the bonding position to the rest of the molecule and the alpha position is shown by the atoms labeled with a * symbol, and
R16 and R17 are independently selected from hydrogen, halo, unsubstituted or substituted lower alkyl (especially C1-C4alkyl), unsubstituted or substituted lower alkenyl, unsubstituted or substituted lower alkynyl, unsubstituted or substituted lower alkoxy, unsubstituted or substituted lower alkylamino, unsubstituted or substituted cycloalkyl or unsubstituted or substituted cycloalkenyl.

In an embodiment, R16 and R17 are independently selected from hydrogen, methyl or ethyl.
In an embodiment, at least one of R16 and R17 is not hydrogen.
In an embodiment of the present invention, R1 is of formula (AB) shown above; and
In a specific embodiment of the present invention, R1 is of formula (AB) shown above; and
R16 and R17 are each methyl.
Preferably R1 is unsubstituted or substituted pyrazolyl. Preferably the pyrazolyl is substituted, preferably by one, two or three substituents, wherein said substituents may for example be independently selected from halo, unsubstituted or substituted alkyl, unsubstituted or substituted alkenyl, unsubstituted or substituted alkynyl, unsubstituted or substituted lower alkoxy, unsubstituted or substituted lower alkylamino, unsubstituted or substituted alkoxy lower alkyl, unsubstituted or substituted cycloalkyl, unsubstituted or substituted cycloalkenyl, unsubstituted or substituted carbamoyl lower alkyl, lower mono- and di-alkyl carbamoyl lower alkyl, unsubstituted or substituted cycloaminocarbonyl lower alkyl, unsubstituted or substituted heterocyclylcarbonyl lower alkyl, unsubstituted or substituted hydroxyl lower alkyl, unsubstituted or substituted carboxy lower alkyl, halo-loweralkyl, hydroxycarbonyl-loweralkyl, morpholinecarbonylalkyl, hydroxy or amino.
Preferred substituents are selected from the group consisting of halo, lower alkyl, lower alkenyl, lower alkynyl, cycloloweralkyl, hydroxy, amino, halo lower alkyl, 2-hydroxyethyl, methoxyethyl, hydroxycarbonylmethyl (HOC(O)CH2—), dialkylaminocarbonylmethyl e.g. dimethylaminocarbonylmethyl (Me2NC(O)CH2—) or ethylmethylaminocarbonylmethyl (EtMeNC(O)CH2—), (methoxyethyl)(methyl)aminocarbonylmethyl ((MeOEt)(Me)NC(O)CH2—), azetidinylcarbonylmethyl e.g. 2-azetidin-1-yl-2-oxo-ethyl, morpholinecarbonylmethyl, (4-methylpiperazin-1yl)carbonylmethyl.
It is preferred that the substituent (if mono-substituted) or at least one of the substituents (if two or three substituents are present) is bonded to the pyrazole ring at the alpha position to the ring atom which bonds the pyrazole ring to the rest of the molecule (that is, the alpha position is at a position on the pyrazole ring which is next to the pyrazole ring atom which is bonded to the imidazoquinolinone part of the molecule). The pyrazole ring atom which is bonded to the rest of the molecule (i.e. the imidazoquinolinone part) is preferably a carbon atom. Thus, preferred pyrazolyl groups are alpha-substituted pyrazolyl. For the avoidance of doubt the ring atom at the alpha position may be a carbon or nitrogen ring atom. Thus an embodiment of the invention includes compounds of formula (I) wherein R1 is a group selected from:
wherein, the curved line indicates the bonding position to the rest of the molecule and the alpha position is shown by the atoms labeled with a * symbol, and

Other starting materials are either known in the art, can be prepared according to methods that are known in the art, e.g., in analogy to the methods described hereinabove or in the examples, and/or are commercially-available.
The present invention relates also to novel starting materials and/or intermediates and to processes for their preparation. The starting materials used and the reaction conditions selected are preferably those that result in the compounds described as being preferred.
Salts of compounds of formula (I) having at least one salt-forming group may be prepared in a manner known per se. For example, salts of compounds of formula (I) having acid groups may be formed, e.g., by treating the compounds with metal compounds, such as alkali metal salts of suitable organic carboxylic acids, e.g., the sodium salt of 2-ethylhexanoic acid; with organic alkali metal or alkaline earth metal compounds, such as the corresponding hydroxides, carbonates or hydrogen carbonates, such as sodium or potassium hydroxide, carbonate or hydrogen carbonate; with corresponding calcium compounds or with ammonia or a suitable organic amine, stoichiometric amounts or only a small excess of the salt-forming agent preferably being used. Acid addition salts of compounds of formula (I) are obtained in customary manner, e.g., by treating the compounds with an acid or a suitable anion exchange reagent. Internal salts of compounds of formula (I) containing acid and basic salt-forming groups, e.g., a free carboxy group and a free amino group, may be formed, e.g., by the neutralization of salts, such as acid addition salts, to the isoelectric point, e.g., with weak bases, or by treatment with ion exchangers.
Salts can be converted in customary manner into the free compounds; metal and ammonium salts can be converted, e.g., by treatment with suitable acids; and acid addition salts, e.g., by treatment with a suitable basic agent.
Mixtures of isomers obtainable according to the invention can be separated in a manner known per se into the individual isomers; diastereoisomers can be separated, e.g., by partitioning between polyphasic solvent mixtures, recrystallization and/or chromatographic separation, e.g., over silica gel or by, e.g., medium pressure liquid chromatography over a reversed phase column; and racemates can be separated, e.g., by the formation of salts with optically pure salt-forming reagents and separation of the mixture of diastereoisomers so obtainable, e.g., by means of fractional crystallization, or by chromatography over optically active column materials.
Intermediates and final products can be worked up and/or purified according to standard methods, e.g., using chromatographic methods, distribution methods, re-crystallization and the like.
Additional Process Steps
In the additional process steps, carried out as desired, functional groups of the starting compounds which should not take part in the reaction may be present in unprotected form or may be protected, e.g., by one or more protecting groups. The protecting groups are then wholly or partly removed according to one of the known methods.
Protecting groups, and the manner in which they are introduced and removed are described, e.g., Protective Groups in Organic Chemistry, Plenum Press, London, N.Y. (1973); Methoden der organischen Chemie, Houben-Weyl, 4th Edition, Vol. 15/1, Georg-Thieme-Verlag, Stuttgart (1974); and Theodora W. Greene, Protective Groups in Organic Synthesis, John Wiley & Sons, NY (1981). A characteristic of protecting groups is that they can be removed readily, i.e., without the occurrence of undesired secondary reactions, e.g., by solvolysis, reduction, photolysis or alternatively under physiological conditions.
The end products of formula (I) may however also contain substituents that can also be used as protecting groups in starting materials for the preparation of other end products of formula (I). Thus, within the scope of this text, only a readily removable group that is not a constituent of the particular desired end product of formula (I) is designated a “protecting group”, unless the context indicates otherwise.

Skin Penetration
The skin penetration/permeation properties of two representative compounds of the present invention were tested as follows:
In Vitro Test to Determine Skin Penetration and Permeation Properties
The compounds were applied as 0.5% solutions in propylene glycol to pig skin mounted in static Franz-type diffusion cells. At the end of a 48 hours exposure time, drug concentrations were measured in the skin (after removal of stratum corneum) and in the receiver.
In conclusion, both examples penetrate well into pig skin (pig skin is similar to human skin regarding barrier function and architecture) in vitro, while permeation rate through pig skin is low, indicating a low systemic exposure.
In Vivo Test to Determine Penetration into Dermis of Topically Treated Pigs
Small skin areas (4 cm2) on the dorsolateral back of young domestic pigs were treated topically with 0.5% solutions at different time intervals (1-8 hrs) prior to drug level determination. Skin flaps with the treated sites in the centre were dissected and removed. The skin flaps were spread, and heated metal blocks placed on the test sites for 1 minute to induce separation of epidermis from the dermis. After removal of the loosened epidermal sheets, 1 mm thick dermal sheets were prepared from the treated, de-epidermized skin with a dermatome. From these sheets 6 mm punch samples (6 mm Ø) were collected and analysed for test compound concentration by LC/MS. The procedure described was done with careful avoidance of contamination of the dermal samples with compound attached superficially to the epidermis.
The following table provides AUC values of the agents of the invention in pig dermis when applied epicutaneously in the identified compositions (n=8).
AUC means area under the curve, and is a well known term in clinical pharmacology. The AUC value describes the total uptake of the agent in a time interval.
In conclusion, both examples penetrate well into pig skin in vivo after a single application, confirming in vitro data described above.

PI3Kα BV-1075 p85(iSH2)-12 XGly Linker-p110a(D20aa)-C-Term His Tag
The construct for Baculovirus BV-1075 is generated by a three-part ligation comprised of a p85 fragment and a p110-a fragment cloned into vector pBlueBac4.5. The p85 fragment is derived from plasmid p1661-2 digested with Nhe/Spe. The p110-a fragment derived from LR410 (see above) as a SpeI/HindIII fragment. The cloning vector pBlueBac4.5 (Invitrogen) is digested with Nhe/HindIII. This results in the construct PED 153.8
The p85 component (iSH2) is generated by PCR using ORF 318 (described above) as a template and one forward primer
and two reverse primers,
The two reverse primers overlap and incorporate the 12x Gly linker and the N-terminal sequence of the p110a gene to the SpeI site. The 12x Gly linker replaces the linker in the BV1052 construct. The PCR fragment is cloned into pCR2.1 TOPO (Invitrogen). Of the resulting clones, p1661-2 is determined to be correct. This plasmid is digested with Nhe and SpeI and the resulting fragment is gel-isolated and purified for sub-cloning.
The p110-a cloning fragment is generated by enzymatic digest of clone LR410 (see above) with Spe I and HindIII. The SpeI site is in the coding region of the p110a gene. The resulting fragment is gel-isolated and purified for sub-cloning.
The cloning vector, pBlueBac4.5 (Invitrogen) is prepared by enzymatic digestion with Nhe and HindIII. The cut vector is purified with Qiagen (Quiagen N.V, Venlo, Netherlands) column and then dephosphorylated with Calf Intestine alkaline phosphatase (CIP) (New England BioLabs, Ipswich, Mass.). After completion of the CIP reaction the cut vector is again column purified to generate the final vector. A 3 part ligation is performed using Roche Rapid ligase and the vendor specifications.

Expression:
Methods to Generate Recombinant Baculovirus and Protein for PI3K Isoforms:
The pBlue-Bac4.5 (for a, b, and d isoforms) or pVL1393 (for g) plasmids containing the different PI3 kinase genes are co-transfected with BaculoGold WT genomic DNA (BD Biosciences, Franklin Lakes, N.J., USA) using methods recommended by the vendor. Subsequently, the recombinant baculovirus obtained from the transfection is plaque-purified on Sf9 insect cells to yield several isolates expressing recombinant protein. Positive clones are selected by anti-HIS or anti-isoform antibody western. For PI3K alpha and delta isoforms, a secondary plaque-purification is performed on the first clonal virus stocks of PI3K. Amplification of all baculovirus isolates is performed at low multiplicity of infection (moi) to generate high-titer, low passage stock for protein production. The baculoviruses are designated BV1052 (α) and BV1075 (α), BV949 (β), BV1060 (δ) and BV950 (γ).
Protein production involves infection (passage 3 or lower) of suspended Tn5 (Trichoplusia ni) or TiniPro (Expression Systems, LLC, Woodland, Calif., USA) cells in protein-free media at moi of 2-10 for 39-48 hours in 2 L glass Erlenmyer flasks (110 rpm) or wave-bioreactors (22-25 rpm). Initially, 10 L working volume wave-bioreactors are seeded at a density of 3e5 cells/ml at half capacity (5 L). The reactor is rocked at 15 rpm during the cell growth phase for 72 hours, supplemented with 5% oxygen mixed with air (0.2 L per minute). Immediately prior to infection, the wave-reactor cultures are analyzed for density, viability and diluted to approximately 1.5e6 cell/ml. 100-500 ml of high titer, low passage virus is added following 2-4 hours of additional culture. Oxygen is increased to 35% for the 39-48 hour infection period and rocking platform rpm increased to 25. During infection, cells are monitored by Vicell viability analyzer (Beckman Coulter, Inc, Fullerton, Calif., USA) bioprocess for viability, diameter and density. Nova Bioanalyzer (NOVA Biomedical Corp., Waltham, Mass., USA) readings of various parameters and metabolites (pH, O2 saturation, glucose, etc.) are taken every 12-18 hours until harvest. The wave-bioreactor cells are collected within 40 hours post infection. Cells are collected by centrifugation (4 degrees C. at 1500 rpm), and subsequently maintained on ice during pooling of pellets for lysis and purification. Pellet pools are made with small amounts of cold, un-supplemented Grace's media (w/o protease inhibitors).
PI3K Alpha Purification Protocol For HTS (BV1052)
PI3K alpha is purified in three chromatographic steps: immobilized metal affinity chromatography on a Ni Sepharose resin (GE Healthcare, belonging to General Electric Company, Fairfield, Conn., USA), gel filtration utilizing a Superdex 200 26160 column (GE Healthcare), and finally a cation exchange step on a SP-XL column (GE Healthcare). All buffers are chilled to 4° C. and lysis is performed chilled on ice. Column fractionation is performed rapidly at room temperature.
Typically frozen insect cells are lysed in a hypertonic lysis buffer and applied to a prepared IMAC column. The resin is washed with 3-5 column volumes of lysis buffer, followed by 3-5 column volumes wash buffer containing 45 mM imidazole, and the target protein is then eluted with a buffer containing 250 mM imidazole. Fractions are analyzed by Coomassie stained SDS-PAGE gels, and fractions containing target protein are pooled and applied to a prepared GFC column. Fractions from the GFC column are analyzed by Coomassie stained SDS-PAGE gels, and fractions containing target protein are pooled. The pool from the GFC column is diluted into a low salt buffer and applied to a prepared SP-XL column. The column is washed with low salt buffer until a stable A280 baseline absorbance is achieved, and eluted using a 20 column volume gradient from 0 mM NaCl to 500 mM NaCl. Again, fractions from the SP-XL column are analyzed by Coomassie stained SDS-PAGE gels, and fractions containing the target protein are pooled.

IC50 is determined by a four parameter curve fitting routine that comes along with “excel fit”. A 4 Parameter logistic equation is used to calculate IC50 values (IDBS XLfit) of the percentage inhibition of each compound at 8 concentrations (usually 10, 3.0, 1.0, 0.3, 0.1, 0.030, 0.010 and 0.003 μM). Alternatively, IC50 values are calculated using idbsXLfit model 204, which is a 4 parameter logistic model.
Yet alternatively, for an ATP depletion assay, compounds of the formula (I) to be tested are dissolved in DMSO and directly distributed into a white 384-well plate at 0.5 μL per well. To start the reaction, 10 μL of 10 nM PI3 kinase and 5 μg/mL 1-alpha-phosphatidylinositol (PI) are added into each well followed by 10 μL of 2 μM ATP. The reaction is performed until approx 50% of the ATP is depleted, and then stopped by the addition of 20 μL of Kinase-Glo solution (Promega Corp., Madison, Wis., USA). The stopped reaction is incubated for 5 minutes and the remaining ATP is then detected via luminescence. IC50 values are then determined.
Some of the compounds of formula (I) show a certain level of selectivity against the different paralogs PI3K alpha, beta, gamma and delta.
The range of activity, expressed as IC50, in these assays is preferably between 1 nM and 5000 nM, more preferably between 1 nM and about 1000 nM
The efficacy of the compounds of formula I and salts thereof as mTor kinase inhibitors can be demonstrated as follows
Biochemical Assay for m-TOR by TR-FRET.
Assay components are purchased from Invitrogen Corporation (Carlsbad/Calif., USA): GFP-4EBP1 (Cat. No. PV4759), Tb3+-α-p4EBP1 [pThr46] Antibody (Cat. No. PV4757), proprietary TR-FRET dilution buffer (Cat. No. PV3574), mTOR protein (Cat. No. PV4753).
50 nL of compound dilutions (final concentration of 10, 3.0, 1.0, 0.3, 0.1, 0.03, 0.01 and 0.003 μM) are dispensed onto black 384-well low volume non-binding polystyrene (Cat. No. NBS#3676, Corning, Lowell/Mass., USA). Then 5 μL of ATP (8 μM final concentration) and GFP-4EBP1 (400 nM final concentration) with 5 μL mTOR proteins (0.5 nM final concentration) are incubated at rt. The standard reaction buffer for the TR-FRET mTOR assay contained 50 mM HEPES pH 7.5, 10 mM MnCl2, 50 mM NaCl, 1 mM EGTA, 1 mM DTT. Reactions were stopped with 10 μL of a mixture of EDTA containing the Tb3+-α-p4EBP1[pT46] detection Ab (0.5 nM) in TR-FRET dilution buffer (proprietary to IVG). Plates are read 15 mins later in a Synergy2 reader using an integration time of 0.2 seconds and a delay of 0.1 seconds. Control for the 100% inhibition of the kinase reaction is performed by replacing the mTOR kinase by the standard reaction buffer. The control for the 0% inhibition is given by the solvent vehicle of the compounds (90% DMSO in H2O). A standard compound is used as a reference compound and included in all assay plates in the form of 16 dilution points in duplicate.
The range of activity, expressed as IC50, in this assay is preferably between 1 nM and 5000 nM, more preferably between 1 nM and about 1000 nM.
The efficacy of the compounds of the invention in blocking the activation of the PI3K/PKB pathway was demonstrated in cellular settings using a reverse protein array assay for sensitive quantification of compound of formula I mediated inhibition of PKB Ser473 phosphorylation in Rat1 cells stably transfected with activated versions of PI3-kinase isoforms alpha, beta or delta:
Cells and Cell Culture Conditions:
Rat1 cell lines stably expressing a myr-HA-tagged, constitutively active subunit of the catalytic PI3K class I p110 isoform α, β or δ (addition of a myristylation signal at the N-terminus of p110 isoforms has been shown to lead to constitutive activation of PI3K and corresponding downstream signals, such as phosphorylation of PKB at Ser473) were cultivated in Dulbecco's modified Eagle's medium (DMEM high Glucose, GIBCO, cat. No. 41956-039) supplemented with 10% heat inactivated fetal bovine calf serum (Amimed, cat. No. 2-01F16-I), 1% L-Glutamine (Invitrogen, cat. No. 25030-02), 1% penicillin-streptomycin (GIBCO, cat. No. 15140-114) and 10 μg/ml Puromycine (Sigma, cat. No. P9620).
Compound Treatment of Cells and Preparation of Samples:
The Rat1-myr-HA-p110 alpha, beta and delta cells were trypsinized and counted with a CASY TT cell counter (Schärfe System GmbH, Reutlingen Germany). The cells were diluted in fresh DMEM complete medium and 3×104cells/150 μl/well seeded in 96-well TPP-tissue culture plates (TPP, cat. No. 92096). The plates were incubated at 37° C. and 5% CO2 under humidified condition for at least 20 h. Compound of formula I working solutions were prepared freshly as serial 8 step dilutions (vol/vol) in DMSO on the day of the experiment. The working solutions were further diluted 1/500 in cell culture medium to get final compound concentrations of 10, 3.333, 1.111, 0.370, 0.123, 0.041, 0.014, 0.005 μM. The final DMSO concentration was kept constant at 0.2%. cell culture medium containing 0.2% DMSO was used as vehicle treatment control. Post incubation, the cells were treated with the serial compound dilution. 50 μl of the compound medium mixture was added to the wells containing cells and 150 μl DMEM medium and incubated for 30 minutes (37° C., 5% CO2). After 30 minutes of incubation, the medium mixture was quickly removed by aspiration. For cell lysis, a mixture of 10% CLB1 CeLyA lysis buffer (Zeptosens, cat. No. 9000), 90% CSBL1 CeLyA spotting buffer (Zeptosens, cat. No. 9020) was freshly prepared and supplemented with 1% Octyl β-D-glucopyranoside (SIGMA, cat. No. 08001-5G) and 1 mM Na-Orthovanadate (Sigma, cat No. S-6508). 50 μl of the described lysis buffer mix was added to each well, followed by 10 minutes of incubation on ice. After an additional freeze-thaw cycle, another 50 μl of the lysis buffer mix without Octyl β-D-glucopyranoside was added to the wells, and 90 μl of the cell lysate was transferred to a 96-well V-bottom plate (Fisher Scientific, cat. No. 6067Y), followed by a centrifugation step (5 min, 1500 rpm at 19° C. in an Eppendorf 5810R centrifuge) to remove the unlysed cell debris.
Spotting of the ZeptoMARK® Chips:
The samples were spotted onto ZeptoMARK® PWG protein microarray chips (Zeptosens, Witterswil, Switzerland) with the piezoelectric microdispense-based, non-contact Nano-Plotter 2.1 (GeSiM, Grosserknnannsdorf, Germany). Each sample was spotted at 4 different sample concentrations (d1=100%, d2=75%, d3=50%, d4=25%) by diluting the cell lysate with the corresponding volume of lysis buffer mix. After spotting the ZeptoMARK® protein microarrays, the chips are incubated for 1 hour at 37° C. To receive a uniform blocking result, the CeLyA blocking buffer BB1 (Zeptosens, cat. No. 9040) is administered via an ultrasonic nebulizer. After 20 minutes of blocking the chips are extensively rinsed with deionized water (Milli-Q quality, 18 MΩ×cm) and dried in a nitrogen air flow.
ZeptoREADER Signal Detection and Data Analysis:
After the sample spotting and blocking procedure, the ZeptoMARK® chips were transferred to the ZeptoCARRIER (Zeptosens, cat. No. 1100), whose six flow cells individually address the six arrays on a chip, and washed twice with 200 μl CAB1 CeLyA assay buffer (Zeptosens, cat. No. 9032). The assay buffer was then aspirated and each compartment incubated with 100 μl of the primary target antibody (pAkt Ser473; CST#9271) at RT over night. Post incubation, the primary antibody was removed, the arrays washed twice with CAB1 buffer and further incubated with 100 μl of Alexa fluor 647-labeled anti rabbit IgG Fab fragments (Invitrogen; #Z25305) for one hour at RT in the dark. After incubation, the arrays were washed twice with 200 μl CAB1 buffer. The fluorescence of the target-bound Fab fragments is read out on the ZeptoReader (Zeptosens, Witterswil, Switzerland) using a laser (excitation wavelength 635 nm) and a CCD camera. The fluorescence signal was assessed with exposure times of 1, 3, 5 and 10 seconds, depending on the intensity of the signal. The resulting four images taken per array are stored as 16-bit TIF files.
The fluorescence images for each array were analyzed with the ZeptoVIEW Pro 2.0 software (Zeptosens, Witterswil, Switzerland) and the relative fluorescence intensity for each signal was calculated. The range of activity, expressed as IC50, in this assay is preferably between about 1 nM and about 10 μM, more preferably between about 1 nM and about 1 μM.
The efficacy of the compounds of the invention in displaying an inhibitory effect downstream of mTORC1 complex (mTOR/raptor) was demonstrated in cellular setting using a reverse protein array assay for sensitive quantification of drug-mediated inhibition of S6 Ribosomal Protein phosphorylation Ser235/236 in TSC1 null mouse embryo fibroblast (MEF) cells.
Cells and Cell Culture Conditions:

No. 15140-114) at 37° C. in a 5% CO2 and 95% relative humidity atmosphere incubator.
Treatment of Cells and Preparation of Samples:
The TSC1−/− cells were trypsinized and counted with a CASY TT cell counter (Schärfe System GmbH, Reutlingen Germany). The cells were diluted in fresh DMEM complete medium and 0.75×104 cells/150 μl/well seeded in 96-well TPP-tissue culture plates (TPP, cat. No. 92096). The plates were incubated at 37° C. and 5% CO2 under humidified condition for at least 20 h. Working solutions were prepared freshly as serial 8 step dilutions (vol/vol) in DMSO on the day of the experiment. The working solutions were further diluted 1/5000 in cell culture medium to get final compound concentrations of 1, 0.3333, 0.1111, 0.037, 0.0123, 0.041, 0.0014, 0.005 μM. The final DMSO concentration was kept constant at 0.02%. cell culture medium containing 0.02% DMSO was used as vehicle treatment control. Post incubation, the cells were treated with the serial compound dilution. 50 μl of the compound medium mixture was added to the wells containing cells and 150 μl DMEM medium and incubated for 60 minutes (37° C., 5% CO2). After 60 minutes of incubation, the medium mixture was quickly removed by aspiration. For cell lysis, a mixture of 10% CLB1 CeLyA lysis buffer (Zeptosens, cat. No. 9000), 90% CSBL1 CeLyA spotting buffer (Zeptosens, cat. No. 9020) was freshly prepared and supplemented with 1% Octyl β-D-glucopyranoside (SIGMA, cat. No. 08001-5G) and 1 mM Na-Orthovanadate (Sigma, cat No. S-6508). 50 μl of the described lysis buffer mix was added to each well, followed by 10 minutes of incubation on ice. After an additional freeze-thaw cycle, another 50 μl of the lysis buffer mix without Octyl β-D-glucopyranoside was added to the wells, and 90 μl of the cell lysate was transferred to a 96-well V-bottom plate (Fisher Scientific, cat. No. 6067Y), followed by a centrifugation step (5 min, 1500 rpm at 19° C. in an Eppendorf 5810R centrifuge) to remove the unlysed cell debris.
Spotting of the ZeptoMARK° Chips:
The spotting of the chips follows the previous described method.
ZeptoREADER Signal Detection and Data Analysis:
The signal detection and the data analysis follows the previous described method using the pS6 ribosomal protein Ser235/236 (CST, cat. No. #2211) as a primary antibody.
The range of activity, expressed as IC50, in this assay is preferably between about 0.1 nM and about 1 μM, more preferably between about 0.1 nM and about 0.5 μM.
There are also experiments to demonstrate the antitumor activity of compounds of the formula (I) in vivo.
For example, female Harlan (Indianapolis, Ind., USA) athymic nu/nu mice with s.c. transplanted human glioblastoms U87MG tumors can be used to determine the anti-tumor activity of PI3 kinase inhibitors. On day 0, with the animals under peroral Forene® (1-chloro-2,2,2-trifluoroethyldifluormethylether, Abbot, Wiesbaden, Germany) narcosis, a tumor fragment of approximately 25 mg is placed under the skin on the animals' left flank and the small incised wound is closed by means of suture clips. When tumors reach a volume of 100 mm3, the mice are divided at random into groups of 6-8 animals and treatment commences. The treatment is carried out for a 2-3 weeks period with peroral, intravenous or intra-peritoneal administration once daily (or less frequently) of a compound of formula (I) in a suitable vehicle at defined doses. The tumors are measured twice a week with a slide gauge and the volume of the tumors is calculated.
As an alternative to cell line U87MG, other cell lines may also be used in the same manner, for example,
