Description

Field of the invention The present invention relates to bicyclic compounds. These bicyclic compounds are useful as TEAD binders and / or inhibitors of YAP-TEAD and TAZ-TEAD protein-protein interaction or binding and for the prevention and / or treatment of cancer and other severe disorders and diseases. Background of the invention In recent years the Hippo pathway has become a target of interest for the treatment of hyperproliferative disorders and diseases, in particular cancer (S. A. Smith et al., J. Med. Chern. 2019, 62, 1291-1305; K. C. Lin et al., Annu. Rev. Cancer Biol. 2018, 2:59-79; C.-L. Kim et al., Cells (2019), 8, 468; K. F. Harvey et al., Nature Reviews Cancer, Vol. 13, 246-257 (2013)). The Hippo pathway regulates cell growth, proliferation, and migration. It is assumed that in mammals the Hippo pathway acts as a tumor suppressor, and dysfunction of Hippo signaling is frequently observed in human cancers. Furthermore, as the Hippo pathway plays a role in several biological processes - like in self-renewal and differentiation of stem cells and progenitor cells, wound healing and tissue regeneration, interaction with other signaling pathways such as Wnt - its dysfunction may also play a role in human diseases other than cancer (C.-L. Kim et al., Cells (2019), 8, 468; Y. Xiao et al., Genes & Development (2019) 33: 1491-1505; K. F. Harvey et al., Nature Reviews Cancer, Vol. 13, 246-257 (2013)). While several aspects of the pathway activity and regulation are still subject to further research, it is already established that in its “switched-on”-state the Hippo pathway involves a cascade of kinases (including Mst 1 / 2 and Lats 1 / 2) in the cytoplasm which results in the phosphorylation of two transcriptional coactivators, YAP (Yes-associated protein) and TAZ (Transcription co-activator with PDZ binding motif). Phosphorylation of YAP / TAZ leads to their sequestration in the cytoplasm and eventually to their degradation. In contrast, when the Hippo pathway is “switched-off” or dysfunctions, the nonphosphorylated, activated YAP / TAZ co-activators are translocated into the cell nucleus. Their major target transcription factors are the four proteins of the Transcriptional enhanced associate domain (TEAD) transcription factor family (TEAD1-4). Binding of YAP or TAZ to and activation of TEAD (or other transcription factors) have shown to induce the expression of several genes many of which mediate cell survival and proliferation. Thus, activated, nonphosphorylated YAP and TAZ may act as oncogenes, while the activated, switched-on Hippo pathway may act as a tumor suppressor by deactivating, i.e. phosphorylating YAP and TAZ. Furthermore, the Hippo pathway may also play a role in resistance mechanisms of cancer cells to oncology and immune-oncology therapy (R. Reggiani et al., BBA - Reviews on Cancer 1873 (2020) 188341, 1-11). Recently, small molecule inhibtors have been described as pan-TEAD inhibitors, i.e., as compounds which bind not only to one of the TEAD family members but to more than one and in particular to all four human TEAD paralogs and thereby block YAP / TAZ binding (T.J. Hagenbeek, et al., Nature Cancer, 4, 812-828 (2023); WO 2021 / 108483 A1). Consequently, the dysfunction or aberrant regulation of the Hippo pathway as a tumor suppressor is believed to be an important event in the development of a wide variety of cancer types and diseases. Therefore, inhibition of YAP, TAZ, TEAD, and YAP-TEAD or TAZ-TEAD protein-protein interaction by pharmacological intervention appears to be a reasonable and valuable strategy to prevent and / or treat cancer and other hyperproliferative disorders and diseases associated with the dysfunction of the Hippo pathway. It may further be useful to inhibit the binding not only to one family member of TEAD, but even to two, three and / or all four TEAD paralogs. Description of the invention The present invention provides compounds that may be useful in the prevention and / or treatment of medical conditions, disorders and / or diseases, in particular of hyperproliferative disorders or diseases, which compounds are TEAD binders and / or inhibitors of YAP-TEAD or TAZ-TEAD protein-protein interaction.

In the context of the present invention“"Ci-3-alkylene”" refers to an alkylene moiety with 1, 2 and 3, respectively, -CH2- groups; the term“"alkylene”", however, not only comprises linear alkylene groups, i.e.“"alkylene chains", but branched alkylene groups as well. The term "Ci-6-alkylene" refers to an alkylene moiety that is either linear, i.e. an alkylene chain, or branched and has 1, 2, 3, 4, 5 or 6 carbon atoms. The term "C2-6-alkylene" refers to an alkylene moiety with 2, 3, 4, 5, or 6 carbon atoms, while a "C3-4-alkylene" refers to an alkylene moiety with 3 or 4 carbon atoms and"C2-3-alkylene" refers to an alkylene moiety with 2 or 3 carbon atoms. A substituted alkylene is a group in which one or more methylene hydrogen atoms are replaced by (or with) a substituent.

A substituted alkenylene chain is a polymethylene group containing at least one double bond in which one or more hydrogen atoms are replaced with a substituent. Suitable substituents include those described herein for a substituted aliphatic group. The term “alkenylene” not only refers to straight-chain divalent alkenylene radicals, i.e. an alkenylene chain, but to branched alkenylene groups as well. The term “C2-6-alkenylene” refers to an alkenylene radical having 2, 3, 4, 5, or 6 carbon atoms. The term “halogen” means F, Cl, Br, or I. In particular, “halogen” refers to F. The term “heteroatom” means one or more of oxygen (0), sulfur (S), or nitrogen (N), including any oxidized form of nitrogen or sulfur, e.g. N-oxides, sulfoxides and sulfones; the quaternized form of any basic nitrogen or a substitutable nitrogen of a heterocyclic or heteroaromatic ring, for example N (as in 3,4-dihydro-2 / - / -pyrrolyl), NH (as in pyrrolidinyl) or N-SUB with SUB being a suitable substituent (as in N-substituted pyrrolidinyl). The term “aryl” used alone or as part of a larger moiety as in “aralkyl”, “aralkoxy”, or “aryloxyalkyl”, refers to monocyclic, bicyclic and tricyclic ring systems having a total of five to fourteen ring members, that ring members being carbon atoms, wherein at least one ring in the system is aromatic, i.e., it has (4n+2) it (pi) electrons (with n being an integer selected from 0, 1,2, 3, 4, 5), which electrons are delocalized over the system, and wherein each ring in the system contains three to seven ring members. Preferably, all rings in the aryl system or the entire ring system are aromatic. The term “aryl” is used interchangeably with the term “aryl ring”. In certain embodiments of the present invention, “aryl” refers to an “aromatic ring system”. More specifically, those aromatic ring systems may be mono-, bi- or tricyclic with 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 ring carbon atoms. Even more specifically, those aromatic ring systems may be mono- or bicyclic with 6, 7, 8, 9, 10 ring carbon atoms. Exemplary aryl groups are phenyl, biphenyl, naphthyl, anthracyl and the like, which may be unsubstituted or substituted with one or more identical or different substituents. Also included within the scope of the terms “aryl” or “aromatic ring system”, as they are used herein, is a group in which an aromatic ring is fused to one or more non-aromatic rings, such as indanyl, phthalimidyl, naphthimidyl, phenanthridinyl, or tetrahydronaphthyl, and the like. In the latter case the "aryl" group or substituent is attached to its pendant group via the aromatic part of the ring system. The term “benzo” refers to a six-membered aromatic ring (with carbon ring atoms) that is fused via two adjacent carbon atoms to another ring, being it a cycloaliphatic, aromatic, heteroaromatic or heterocyclic (heteroaliphatic) ring; as a result a ring system with at least two rings is formed in which the benzo ring shares two common carbon atoms with the other ring to which it is fused. For example, if a benzo ring is fused to a phenyl ring, a napthaline ring system is formed, while fusing a benzo ring to a pyridine provides for either a quinoline or an isoquinoline; fusing a benzo ring to a cyclopentene ring provides an indene ring. The terms “heteroaryl” and “heteroar-”, used alone or as part of a larger moiety, e.g., “heteroaralkyl”, or “heteroaralkoxy”, refer to groups having 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 ring atoms (which atoms are carbon and hetero atoms), preferably 5, 6, 9 or 10 ring atoms; having 6, 10, or 14 it (pi) electrons shared in a cyclic array; and having, in addition to carbon atoms, 1,2, 3, 4 or 5 heteroatoms. The term “heteroatom” refers to nitrogen, oxygen, or sulfur, and includes any oxidized form of nitrogen or sulfur, and any quaternized form of a basic nitrogen. In other words, a “heteroaryl” ring or ring system (or a heteroaromatic ring or ring system) may also be described as an aromatic heterocycle. Heteroaryl groups include, without limitation, thienyl, furanyl, pyrrolyl, imidazolyl, pyrazolyl, triazolyl, tetrazolyl, oxazolyl, isoxazolyl, oxadiazolyl, thiazolyl, isothiazolyl, thiadiazolyl, furazanyl, pyridyl (pyridinyl), pyridazinyl, pyrimidinyl, pyrazinyl, indolizinyl, purinyl, naphthyridinyl, pteridinyl, and pyrrolopyridinyI, in particular pyrrolo[2,3-b]pyridinyI.

Nonlimiting examples include indolyl, isoindolyl, benzothienyl (benzothiophenyl), benzofuranyl, dibenzofuranyl, indazolyl, benzimidazolyl, benzothiazolyl, quinolyl, isoquinolyl, cinnolinyl, phthalazinyl, quinazolinyl, quinoxalinyl, 4 / - / -quinolizinyl, carbazolyl, acridinyl, phenazinyl, phenothiazinyl, phenoxazinyl, tetrahydroquinolinyl, tetrahydroisoquinolinyl, 9H-carbazolyl, dibenzofuranyl and pyrido[2,3-b]-1,4-oxazin-3(4 / - / )-one. For example, an indolyl ring may be attached via one of the ring atoms of the sixmembered aryl ring or via one of the ring atoms of the five-membered heteroaryl ring. A heteroaryl group is optionally mono-, bi- or tricyclic. The term “heteroaryl” is used interchangeably with the terms “heteroaryl ring”, “heteroaryl group”, or “heteroaromatic”, any of which terms include rings that are unsubstituted or substituted with one or more identical or different substituents. The term “heteroaralkyl” refers to an alkyl group substituted by a heteroaryl, wherein the alkyl and heteroaryl portions independently are optionally substituted. A heteroaryl ring can be attached to its pendant group at any of its hetero or carbon ring atoms which attachment results in a stable structure or molecule: any of the ring atoms may be unsubstituted or substituted. As used herein, the terms “heterocycle”, “heterocyclyl”, “heterocyclic radical”, and “heterocyclic ring” are used interchangeably and refer to a stable monobi- or tricyclic heterocyclic moiety with 5, 6, 7, 8, 9,10,11,12,13,14 ring atoms wherein 1, 2, 3, 4, 5 of said ring atoms are hetero atoms and wherein that heterocyclic moiety is either saturated or partially unsaturated; heterocyclic moieties that are aromatic rings or ring systems are usually referred to as “heteroaryl” moieties as described hereinabove. Preferably, the heterocycle is a stable saturated or partially unsaturated 3-, 4-, 5-, 6-, or 7-membered monocyclic or 6- 7-, 8- 9-, 10-, or 11-membered bicyclic or 11-, 12-, 13-, or 14-membered tricyclic heterocyclic moiety. When used in reference to a ring atom of a heterocycle, the term “nitrogen” includes a substituted nitrogen. As an example, in a saturated or partially unsaturated ring having 1-3 heteroatoms selected from oxygen, sulfur or nitrogen, the nitrogen is N (as in 3,4-dihydro-2H-pyrrolyl), NH (as in pyrrolidinyl), or N-SUB with SUB being a suitable substituent (as in N-substituted pyrrolidinyl). In the context of the term "heterocycle" the term "saturated" refers to a completely saturated heterocyclic system, like pyrrolidinyl, piperidinyl, morpholinyl, piperidinonyl, tetrahydrofuranyl, thianyl, and dioxothianyl. With regard to the term "heterocycle" the term "partially unsaturated" refers to heterocyclic systems (i) that contain one or more units of unsaturation, e.g. a C=C or a C=Heteroatom bond, but that are not aromatic, for instance, tetrahydropyridinyl; or (ii) in which a (saturated or unsaturated but nonaromatic) heterocyclic ring is fused with an aromatic or heteroaromatic ring system, wherein, however, the "partially unsaturated heterocycle" is attached to the rest of the molecule (its pendant group) via one of the ring atoms of the "heterocyclic" part of the system and not via the aromatic or heteroaromatic part. This first class (i) of "partially unsaturated" heterocycles may also be referred to as "non-aromatic partially unsaturated" heterocycles. This second class (ii) of "partially unsaturated" heterocycles may also be referred to as (bicyclic or tricyclic) "partially aromatic" heterocycles indicating that at least one of the rings of that heterocycle is a saturated or unsaturated but nonaromatic heterocycle that is fused with at least one aromatic or heteroaromatic ring system. Typical examples of these "partially aromatic" heterocycles are 1,2,3,4-tetrahydroquinolinyl and 1,2,3,4-tetrahydroisoquinolinyl. A heterocyclic ring can be attached to its pendant group at any heteroatom or carbon atom that results in a stable structure and any of the ring atoms may be unsubstituted or substituted. Examples of such saturated or partially unsaturated heterocyclic radicals include, without limitation, tetrahydrofuranyl, tetrahydropyranyl, thianyl, dioxothianyl, tetrahydrothiophenyl, pyrrolidinyl, piperidinyl, pyrrolinyl, morpholinyl, tetrahydroquinolinyl, tetrahydro-isoquinolinyl, decahydroquinolinyl, oxazolidinyl, piperazinyl, dioxanyl, dioxolanyl, diazepinyl, oxazepinyl, thiazepinyl, morpholinyl, and quinuclidinyl. The terms “heterocycle”, “heterocyclyl”, “heterocyclyl ring”, “heterocyclic group”, “heterocyclic moiety”, and “heterocyclic radical”, are used interchangeably herein, and also include groups in which a heterocyclyl ring is fused to one or more aryl, heteroaryl, or cycloaliphatic rings, such as indolinyl, 3H—indolyl, chromanyl, phenanthridinyl, or tetrahydroquinolinyl, where the radical or point of attachment is on the heterocyclyl ring. A heterocyclyl group is optionally mono-, bi- or tricyclic. The term “heterocyclylalkyl” refers to an alkyl group substituted by a heterocyclyl, wherein the alkyl and heterocyclyl portions independently are unsubstituted or substituted. The term “unsaturated”, as used herein, means that a moiety or group or substituent has one or more units of unsaturation. As used herein with reference to any rings, ring systems, ring moieties, and the like, the term “partially unsaturated” refers to a ring moiety that includes at least one double or triple bond. The term “partially unsaturated” is intended to encompass rings having multiple sites of unsaturation. In particular, it encompasses (i) non-saturated (mono-, bi- or tricyclic) ring systems without any aromatic or heteroaromatic moiety or part; and (ii) bi- or tricyclic ring systems in which one of the rings of that system is an aromatic or heteroaromatic ring which is fused with another ring that is neither an aromatic nor a heteroaromatic ring, e.g. tetrahydronaphthyl or tetrahydroquinolinyl. The first class (i) of "partially unsaturated" rings, ring systems, ring moieties may also be referred to as "non-aromatic partially unsaturated" rings, ring systems, ring moieties, while the second class (ii) may be referred to as "partially aromatic" rings, ring systems, ring moieties. As used herein, the term “bicyclic”, “bicyclic ring” or “bicyclic ring system” refers to any bicyclic ring system, i.e. carbocyclic or heterocyclic, saturated or having one or more units of unsaturation, i.e. being partially unsaturated or aromatic, having one or more atoms in common between the two rings of the ring system. Thus, the term includes any permissible ring fusion, such as orthofused or spirocyclic. As used herein, the term “heterobicyclic” is a subset of “bicyclic” that requires that one or more heteroatoms are present in one or both rings of the bicycle. Such heteroatoms may be present at ring junctions and are optionally substituted, and may be selected from nitrogen (including N-oxides), oxygen, sulfur (including oxidized forms such as sulfones and sulfonates), phosphorus (including oxidized forms such as phosphates), boron, etc. In some embodiments, a bicyclic group has 7-12 ring members and 0-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur. Likewise, the term “tricyclic”, “tricyclic ring” or “tricyclic ring system” refers to any tricyclic ring system, i.e. carbocyclic or heterocyclic, saturated or having one or more units of unsaturation, i.e. being partially unsaturated or aromatic, in which a bicyclic ring system (as defined above) is fused with another, third ring. Thus, the term includes any permissible ring fusion. As used herein, the term “heterotricyclic” is a subset of “tricyclic” that requires that one or more heteroatoms are present in one or both rings of the tricycle. Such heteroatoms may be present at ring junctions and are optionally substituted, and may be selected from nitrogen (including N-oxides), oxygen, sulfur (including oxidized forms such as sulfones and sulfonates), phosphorus (including oxidized forms such as phosphates), boron, etc. In some embodiments, a tricyclic group has 10-14 ring members and 0-5 heteroatoms independently selected from nitrogen, oxygen, or sulfur. As described herein, certain compounds of the invention contain “substituted” or “optionally substituted” moieties. In general, the term “substituted”, whether preceded by the term “optionally” or not, means that one or more hydrogens of the designated moiety are replaced with a suitable substituent. “Substituted” applies to one or more hydrogens that are either explicit or implicit from the structure. Unless otherwise indicated, a “substituted” or “optionally substituted” group has a suitable substituent at each substitutable position of the group, and when more than one position in any given structure is substituted with more than one substituent selected from a specified group, the substituent is either the same or different at every position. If a certain group, substituent, moiety or radical is "mono-substituted", it bears one (1) substituent. If it is "disubstituted", it bears two (2) substituents, being either the same or different; if it is "tri-substituted", it bears three (3) substituents, wherein all three are the same or two are the same and the third is different or all three are different from each other. Combinations of substituents envisioned by this invention are preferably those that result in the formation of stable or chemically feasible compounds. The term “stable”, as used herein, refers to compounds that are not substantially altered when subjected to conditions to allow for their production, detection, and, in certain embodiments, their recovery, purification, and use for one or more of the purposes disclosed herein.

The term “solvates” means addition forms of the compounds of the present invention with solvents, preferably pharmaceutically acceptable solvents that contain either stoichiometric or non-stoichiometric amounts of solvent. Some compounds have a tendency to trap a fixed molar ratio of solvent molecules in the crystalline solid state, thus forming a solvate. If the solvent is water the solvate formed is a hydrate, e.g. a hemi-, mono- or dihydrate. If the solvent is alcohol, the solvate formed is an alcoholate, e.g., a methanolate or ethanolate. If the solvent is an ether, the solvate formed is an etherate, e.g., diethyl etherate. The term "N-oxides" means such compounds of the present invention that contain an amine oxide moiety, i.e. the oxide of a tertiary amine group. The compounds of formula I may - also depending on the nature of substituents they may bear - have one or more centers of chirality. They may accordingly occur in various enantiomeric and diastereomeric forms, as the case may be, and be in racemic or optically active form. The invention, therefore, also relates to the optically active forms, enantiomers, racemates, diastereomers, mixtures thereof in all ratios, collectively: “stereoisomers” for the purpose of the present invention, of these compounds. Since the pharmaceutical activity of the racemates or stereoisomers of the compounds according to the invention may differ, it may be desirable to use a specific stereoisomer, e.g. one specific enantiomer or diastereomer. In these cases, a compound according to the present invention obtained as a racemate or even intermediates thereof - may be separated into the stereoisomeric (enantiomeric, diastereoisomeric) compounds by chemical or physical measures known to the person skilled in the art. Another approach that may be applied to obtain one or more specific stereoisomers of a compound of the present invention in an enriched or pure form makes use of stereoselective synthetic procedures, e.g. applying starting material in a stereoisomerically enriched or pure form (for instance using the pure or enriched (R)- or (S)-enantiomer of a particular starting material bearing a chiral center) or utilizing chiral reagents or catalysts, in particular enzymes. In the context of the present invention the term "pure enantiomer" usually refers to a relative purity of one enantiomer over the other (its antipode) of equal to or greater than 95%, preferably > 98 %, more preferably > 98.5%, still more preferably > 99%. Thus, for example, the compounds of the invention which have one or more centers of chirality and which occur as racemates or as mixtures of enantiomers or diastereoisomers can be fractionated or resolved by methods known per se into their optically pure or enriched isomers, i.e. enantiomers or diastereomers. The separation of the compounds of the invention can take place by chromatographic methods, e.g. column separation on chiral or nonchiral phases, or by recrystallization from an optionally optically active solvent or by use of an optically active acid or base or by derivatization with an optically active reagent such as, for example, an optically active alcohol, and subsequent elimination of the radical. In the context of the present invention the term “tautomer” refers to compounds of the present invention that may exist in tautomeric forms and show tautomerism; for instance, carbonyl compounds may be present in their keto and / or their enol form and show keto-enol tautomerism. Those tautomers may occur in their individual forms, e.g., the keto or the enol form, or as mixtures thereof and are claimed separately and together as mixtures in any ratio. The same applies for cis / trans isomers, E / Z isomers, conformers and the like. In one embodiment the compounds of the present invention are in the form of free base or acid - as the case may be -, i.e. in their non-salt (or salt-free) form. In another embodiment the compounds of the present invention are in the form of a pharmaceutically acceptable salt, a pharmaceutically acceptable solvate, or a pharmaceutically acceptable solvate of a pharmaceutically acceptable salt. The term "pharmaceutically acceptable salts" refers to salts prepared from pharmaceutically acceptable bases or acids, including inorganic bases or acids and organic bases or acids. In cases where the compounds of the present invention contain one or more acidic or basic groups, the invention also comprises their corresponding pharmaceutically acceptable salts. Thus, the compounds of the present invention which contain acidic groups, such as carboxyl groups, can be present in salt form, and can be used according to the invention, for example, as alkali metal salts, alkaline earth metal salts, aluminium salts or as ammonium salts. More precise examples of such salts include lithium salts, sodium salts, potassium salts, calcium salts, magnesium salts, barium salts or salts with ammonia or organic amines such as, for example, ethylamine, ethanolamine, diethanolamine, triethanolamine, piperdine, N-methylglutamine or amino acids. These salts are readily available, for instance, by reacting the compound having an acidic group with a suitable base, e.g. lithium hydroxide, sodium hydroxide, sodium propoxide, potassium hydroxide, potassium ethoxide, magnesium hydroxide, calcium hydroxide or barium hydroxide. Other base salts of compounds of the present invention include but are not limited to copper(l), copper(ll), iron(ll), iron (III), manganese(ll) and zinc salts. Compounds of the present invention which contain one or more basic groups, e.g. groups which can be protonated, can be present in salt form, and can be used according to the invention in the form of their addition salts with inorganic or organic acids. Examples of suitable acids include hydrogen chloride, hydrogen bromide, hydrogen iodide, phosphoric acid, sulfuric acid, nitric acid, methanesulfonic acid, p-toluenesulfonic acid, naphthalenedisulfonic acid, sulfoacetic acid, trifluoroacetic acid, oxalic acid, acetic acid, tartaric acid, lactic acid, salicylic acid, benzoic acid, carbonic acid, formic acid, propionic acid, pivalic acid, diethylacetic acid, malonic acid, succinic acid, pimelic acid, fumaric acid, malonic acid, maleic acid, malic acid, embonic acid, mandelic acid, sulfaminic acid, phenylpropionic acid, gluconic acid, ascorbic acid, isonicotinic acid, citric acid, adipic acid, taurocholic acid, glutaric acid, stearic acid, glutamic acid or aspartic acid, and other acids known to the person skilled in the art. The salts which are formed are, inter alia, hydrochlorides, chlorides, hydrobromides, bromides, iodides, sulfates, phosphates, methanesulfonates (mesylates), tosylates, carbonates, bicarbonates, formates, acetates, sulfoacetates, triflates, oxalates, malonates, maleates, succinates, tartrates, malates, embonates, mandelates, fumarates, lactates, citrates, glutarates, stearates, aspartates and glutamates. The stoichiometry of the salts formed from the compounds of the invention may moreover be an integral or non-integral multiple of one. Compounds of the present invention which contain basic nitrogen-containing groups can be quaternized using agents such as (Ci-C4)alkyl halides, for example methyl, ethyl, isopropyl and tert-butyl chloride, bromide and iodide; di(Ci-C4)alkyl sulfates, for example dimethyl, diethyl and diamyl sulfate; (C10-Cis)alkyl halides, for example decyl, dodecyl, lauryl, myristyl and stearyl chloride, bromide and iodide; and aryl(Ci-C4)alkyl halides, for example benzyl chloride and phenethyl bromide. Both water- and oil-soluble compounds according to the invention can be prepared using such salts. If the compounds of the present invention simultaneously contain acidic and basic groups in the molecule, the invention also includes, in addition to the salt forms mentioned, inner salts or betaines (zwitterions). The respective salts can be obtained by customary methods which are known to a person skilled in the art, for example by contacting these with an organic or inorganic acid or base in a solvent or dispersant, or by anion exchange or cation exchange with other salts. The present invention also includes all salts of the compounds of the present invention which, owing to low physiological compatibility, are not directly suitable for use in pharmaceuticals but which can be used, for example, as intermediates for chemical reactions or for the preparation of pharmaceutically acceptable salts. Therefore, the following items are also in accordance with the invention: (a) all stereoisomers or tautomers of the compounds, including mixtures thereof in all ratios; (b) pharmaceutically acceptable salts of the compounds and of the items mentioned under (a); (c) pharmaceutically acceptable solvates of the compounds and of the items mentioned under (a) and (b); (d) N-oxides of the compounds and of the items mentioned under (a), (b), and (c). It will be understood that all references to compounds above and below are meant to include these items, in particular pharmaceutically acceptable solvates of the compounds, or pharmaceutically acceptable solvates of their pharmaceutically acceptable salts. There is furthermore intended that a compound of the present invention includes isotope-labelled forms thereof. An isotope-labelled form of a compound of the formula I is identical to this compound apart from the fact that one or more atoms of the compound have been replaced by an atom or atoms having an atomic mass or mass number which differs from the atomic mass or mass number of the atom which usually occurs naturally. Examples of isotopes which are readily commercially available and which can be incorporated into a compound of the present invention by well-known methods include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine and chlorine, for example 2H (D), 3H, 13C, 14C, 15N, 18O, 17O, 31P, 32P, 33S, 34S, 35S, 36S, 18F and 36CI, respectively. A compound of formula I or a pharmaceutically acceptable salt thereof which contains one or more of the above-mentioned isotopes and / or other isotopes of other atoms is intended to be part of the present invention. An isotope-labelled compound of formula I can be used in a number of beneficial ways. For example, an isotope-labelled compound of the present invention into which, for example, a radioisotope, such as 3H or 14C, has been incorporated is suitable for medicament and / or substrate tissue distribution assays. These radioisotopes, i.e. tritium (3H) and carbon-14 (14C), are particularly preferred owing to simple preparation and excellent detectability. Incorporation of heavier isotopes, for example deuterium (2H), into a compound of formula I has therapeutic advantages owing to the higher metabolicstability of this isotope-labelled compound. Higher metabolic stability translates directly into an increased in vivo half-life or lower dosages, which under most circumstances would represent a preferred embodiment of the present invention. An isotope-labelled compound of formula I can usually be prepared by carrying out the procedures disclosed in the synthesis schemes and the related description, in the example part and in the preparation part in the present text, replacing a non-isotope-labelled reactant by a readily available isotope-labelled reactant. Deuterium (2H; D) can also be incorporated into a compound of formula I for the purpose of manipulating the oxidative metabolism of the compound by way of the primary kinetic isotope effect. The primary kinetic isotope effect is a change of the rate for a chemical reaction that results from exchange of isotopic nuclei, which in turn is caused by the change in ground state energies necessary for covalent bond formation after this isotopic exchange. Exchange of a heavier isotope usually results in a lowering of the ground state energy for a chemical bond and thus cause a reduction in the rate in rate-limiting bond breakage. If the bond breakage occurs in or in the vicinity of a saddle-point region along the coordinate of a multi-product reaction, the product distribution ratios can be altered substantially. For explanation: if deuterium is bonded to a carbon atom at a non-exchangeable position, rate differences of kn / ko = 2-7 are typical. If this rate difference is successfully applied to a compound of the formula I that is susceptible to oxidation, the profile of this compound in vivo can be drastically modified and result in improved pharmacokinetic properties. When discovering and developing therapeutic agents, the person skilled in the art attempts to optimize pharmacokinetic parameters while retaining desirable in vitro properties. It is reasonable to assume that many compounds with poor pharmacokinetic profiles are susceptible to oxidative metabolism. In vitro liver microsomal assays currently available provide valuable information on the course of oxidative metabolism of this type, which in turn permits the rational design of deuterated compounds of the formula I with improved stability through resistance to such oxidative meta-bolism. Significant improvements in the pharmacokinetic profiles of compounds of the formula I are thereby obtained, and can be expressed quantitatively in terms of increases in the in vivo half-life (t1 / 2), concentration at maximum therapeutic effect (Cmax), area under the dose response curve (AUC), and F; and in terms of reduced clearance, dose and materials costs. The following is intended to illustrate the above: a compound of formula I which has multiple potential sites of attack for oxidative metabolism, for example benzylic hydrogen atoms and hydrogen atoms bonded to a nitrogen atom, is prepared as a series of analogues in which various combinations of hydrogen atoms are replaced by deuterium atoms, so that some, most or all of these hydrogen atoms have been replaced by deuterium atoms. Half-life determinations enable favourable and accurate determination of the extent of the extent to which the improvement in resistance to oxidative metabolism has improved. In this way, it is deter-mined that the half-life of the parent compound can be extended by up to 100% as the result of deuterium-hydrogen exchange of this type. Deuterium-hydrogen exchange in a compound of the present invention can also be used to achieve a favourable modification of the metabolite spectrum of the starting compound in order to diminish or eliminate undesired toxic metabolites. For example, if a toxic metabolite arises through oxidative carbonhydrogen (C-H) bond cleavage, it can reasonably be assumed that the deuterated analogue will greatly diminish or eliminate production of the unwanted metabolite, even if the particular oxidation is not a rate-determining step. Further information on the state of the art with respect to deuteriumhydrogen exchange may be found, for example in Hanzlik et al., J. Org. Chern. 55, 3992-3997, 1990, Reider et al., J. Org. Chern. 52, 3326-3334, 1987, Foster, Adv. Drug Res. 14, 1-40, 1985, Gillette et al, Biochemistry 33(10) 29272937, 1994, and Jarman et al. Carcinogenesis 16(4), 683-688, 1995. Furthermore, the present invention relates to pharmaceutical compositions comprising at least one compound of formula I, or its N-oxides, solvates, tautomers or stereoisomers thereof as well as the pharmaceutically acceptable salts of each of the foregoing, including mixtures thereof in all ratios, as active ingredient, together with a pharmaceutically acceptable carrier. For the purpose of the present invention the term “pharmaceutical composition” (or “pharmaceutical formulation”) refers to a composition or product comprising one or more active ingredients, and one or more inert ingredients that make up the carrier, as well as any product which results, directly or indirectly, from combination, complexation or aggregation of any two or more of the ingredients, or from dissociation of one or more of the ingredients, or from other types of reactions or interactions of one or more of the ingredients. Accordingly, the pharmaceutical compositions of the present invention encompass any composition made by admixing at least one compound of the present invention and a pharmaceutically acceptable carrier. It may further comprise physiologically acceptable excipients, auxiliaries, adjuvants, diluents and / or additional pharmaceutically active substance other than the compounds of the invention. The pharmaceutical compositions include compositions and pharmaceutical formulations suitable for oral, rectal, topical, parenteral (including subcutaneous, intramuscular, and intravenous), ocular (ophthalmic), pulmonary (nasal or buccal inhalation), or nasal administration, although the most suitable route in any given case will depend on the nature and seventy of the conditions being treated and on the nature of the active ingredient. They may be conveniently presented in unit dosage form and prepared by any of the methods well-known in the art of pharmacy. A pharmaceutical composition of the present invention may additionally comprise one or more other compounds as active ingredients (drugs), such as one or more additional compounds of the present invention. In a particular embodiment the pharmaceutical composition further comprises a second active ingredient or its N-oxides, solvates, tautomers or stereoisomers thereof as well as the pharmaceutically acceptable salts of each of the foregoing, including mixtures thereof in all ratios, wherein that second active ingredient is other than a compound of formula I; preferably, that second active ingredient is a compound that is useful in the treatment, prevention, suppression and / or amelioration of medicinal conditions or pathologies for which the compounds of the present invention are useful as well and which are listed elsewhere hereinbefore or hereinafter. Such combination of two or more active ingredients or drugs may be safer or more effective than either drug or active ingredient alone, or the combination is safer or more effective than it would be expected based on the additive properties of the individual drugs. Such other drug(s) may be administered, by a route and in an amount commonly used contemporaneously or sequentially with a compound of the invention. When a compound of the invention is used contemporaneously with one or more other drugs or active ingredients, a combination product containing such other drug(s) and the compound of the invention - also referred to as “fixed dose combination” - is preferred. However, combination therapy also includes therapies in which the compound of the present invention and one or more other drugs are administered on different overlapping schedules. It is contemplated that when used in combination with other active ingredients, the compound of the present invention or the other active ingredient or both may be used effectively in lower doses than when each is used alone. Accordingly, the pharmaceutical compositions of the present invention include those that contain one or more other active ingredients, in addition to a compound of the invention. The compounds of the present invention - or N-oxides, solvates, tautomers or stereoisomers thereof and / or the pharmaceutically acceptable salts of each of the foregoing, including mixtures thereof in all ratios - can be used as medicaments. They have been found to exhibit pharmacological activity by binding to TEAD and / or disrupting and / or inhibiting YAP-TEAD and / or TAZ-TEAD protein-protein interaction. It is worth mentioning that some of the compounds of the present invention may not only bind to one of the TEAD family members (TEAD 1,2, 3, or 4) but to more than one TEAD paralog, i.e., to two, three or even all four TEAD paralogs, thereby exhibiting activity as pan-TEAD inhibitors. It is assumed that by this activity the compounds of the present invention may prevent or reverse dysfunction of the Hippo pathway. By preventing its dysfunction, the Hippo pathway may be capable of playing its role as a tumor suppressor. Apart from preventing or reversing dysfunction of the Hippo pathway and independent of upstream Hippo regulation, the pharmacological activity of the compounds of the present invention may also be useful in other pathophysiological scenarios where inhibition or disruption of TEAD binding and / or aberrant YAP-TEAD and / or aberrant TAZ-TEAD signaling would be beneficial. Thus, the compounds of the present invention being TEAD binders and / or inhibitors of YAP-TEAD and / or TAZ-TEAD interaction are useful in particular in the treatment, prevention, suppression and / or amelioration of hyperproliferative disorders and cancer, in particular tumors including solid tumors, of breast cancer, lung cancer, mesothelioma, epithelioid hemangioendothelioma, uveal melanoma, liver cancer, ovarian cancer, squamous cancer, renal cancer, gastric cancer, medulloblastoma, colon cancer, pancreatic cancer, schwannoma, meningioma, glioma, basal cell carcinoma. Without wishing to commit to any specific theory or explanation it may be assumed that the compounds might be able to achieve this by direct effects on the cancer cells and / or indirectly by modulating the response of the immune system against the tumor. Furthermore, the compounds of the present invention may also be useful in the treatment, prevention, suppression and / or amelioration of non-cancerous disorders and diseases, e.g. cardiovascular diseases and fibrosis (like liver fibrosis). In a particular embodiment the compounds of the present invention are for use in the prevention and / or treatment, especially in the treatment of any of the disorders or diseases listed above, preferably of cancer, in particular tumors including solid tumors, of the specific types of cancer disclosed in the previous paragraph; or of any of the non-cancerous disorders or diseases disclosed in the previous paragraph. Another particular embodiment of the present invention is a method for preventing and / or treating, preferably treating a disorder or disease selected from the group consisting of hyperproliferative disorders and cancer, in particular tumors including solid tumors, of the specific types of cancer disclosed in the previous paragraphs; or of any of the non-cancerous disorders or diseases disclosed in the previous paragraphs. Still another particular embodiment of the invention is the use of a compound of the present invention - or N-oxides, prodrugs, solvates, tautomers or stereoisomers thereof and / or the pharmaceutically acceptable salts of each of the foregoing, including mixtures thereof in all ratios - for the manufacturing of a medicament, in particular for preventing and / or treating, preferably treating a disorder or disease selected from the group consisting of hyperproliferative disorders and cancer, in particular tumors including solid tumors, of the specific types of cancer disclosed in the previous paragraphs; or of any of the non-cancerous disorders or diseases disclosed in the previous paragraphs. Preferably, the present invention relates to a compound of the present invention for use in the prevention and / or treatment of a disease - or, alternatively, a method for preventing and / or treating a disease by administering an effective amount of a compound of the present invention ; or, in another alternative, a use of a compound of the present invention for the manufacturing of a medicament for the prevention and / or treatment of a disease- wherein that disease is a cancer, in particular tumors including solid tumors, of the specific types of cancer disclosed in the previous paragraphs; and more preferably, wherein administration of the compound is simultaneous, sequential or in alternation with administration of at least one other active drug agent.

As will be understood by the person skilled in the art of organic synthesis compounds of the present invention, in particular compounds of formula I, are readily accessible by various synthetic routes, some of which are exemplified in the accompanying Experimental Part. The skilled artisan will easily recognize which kind of reagents and reactions conditions are to be used and how they are to be applied and adapted in any particular instance - wherever necessary or useful - in order to obtain the compounds of the present invention. Furthermore, some of the compounds of the present invention can readily be synthesized by reacting other compounds of the present invention under suitable conditions, for instance, by converting one particular functional group being present in a compound of the present invention, or a suitable precursor molecule thereof, into another one by applying standard synthetic methods, like reduction, oxidation, addition or substitution reactions; those methods are well known to the skilled person. Likewise, the skilled artisan will apply - whenever necessary or useful - synthetic protecting (or protective) groups; suitable protecting groups as well as methods for introducing and removing them are well-known to the person skilled in the art of chemical synthesis. In the following general synthetic routes that may be utilized to prepare compounds of the present invention are described in more detail in Schemes A to E below (unless indicated otherwise the various radicals and substituents depicted in the following Schemes have the same meaning as throughout the specification and the accompanying claims): Scheme A The 1 H-pyrrolo[3,2-b]pyridine derivative of formula A is in reaction step a treated with a suitable iodination reagent under appropriate reaction conditions (for instance, with NIS (N-iodo succinimide) in DMF at room temperature) to yield the respective iodo-substituted compound of formula B. In reaction b the compound of formula B is then converted into the compound of formula C by introducing a suitable protecting group, Y1, utilizing a suitable reagent bearing Y1 under appropriate reaction conditions. For instance, the compound of formula B may be reacted with p-tolyl sulfonyl chloride (TsCI) in the presence of triethylamine and 4-dimethylaminopyrdine (DMAP) to provide the compound of formula C with Y1 being p-tolylsulfonyl. Other suitable protecting groups would be, for instance, tert.-butyl carboxylate (-C(=O)-O-tert.-butyl), or triphenylmethyl (trityl). In the next reaction step, step c, the azaindole derivative of formula C is converted into the lactam derivative of formula D utilizing a suitable reagent to cleave the ether moiety in 2-position of the bicyclic ring system, e.g., hydrobromide in acetic acid. This is followed by alkylation of the lactam nitrogen (step d) using both a suitable base to deprotonate the lactam nitrogen and a suitable alkylating agent to yield alkylated bicyclic compound of formula E. A typical procedure would employ a strong lithium organic base like LiHMDS (lithium bis(trimethylsilyl)amide) in DMF and an alkyliodide like methyl iodide or ethyl iodide. The alkylated lactam derivative of formula E may then be converted (step e) into the functionalized bicyclic compound of formula F by replacing the iodine substituent with a suitable boronate, Y3, the introduction of which permits further transformation by C-C or C-N coupling reactions. For instance, to a solution of a compound of formula E in dioxane and triethylamine a suitable boronic acid reagent like 4,4,5,5-tetramethyl-1,3.2-dioxaborolane and a suitable organopalladium catalyst like Pd(PPh3)4 is added introducing the dioxaborolanyl moiety as functional group Y3 into the compound of formula F. Both compounds of formula E and F may be utilized as intermediates for the synthesis of compounds of formula I of the present invention (see Schemes D and E below). Scheme B Compounds of formula E (as depicted in Scheme A above) may alternatively synthesized according the general reaction Scheme B above: By reacting with p-tosyl chloride in triethylamine in the presence of catalytic amounts of DMAP the 1 H-pyrrolo[3,2-b]pyridine derivative of formula A is transformed into the toyslated derivative of formula A-Ts (Ts = p-tolylsulfonyl) (reaction stepf) which in turn is converted into the bicyclic compound of formula H utilizing a suitable reagent to cleave the ether moiety in 2-position, e.g., hydrobromide in acetic acid (step g). Subsequent alkylation (step h) utilizing both a suitable base and a suitable alkylating agent yields the alkylated bicyclic compound of formula J. A typical procedure would employ a strong lithium organic base like LiHMDS (lithium bis(trimethylsilyl)amide) in DMF and an alkyliodide like methyl iodide or ethyl iodide. The p-tosyl protecting group may then be removed by means of a suitable base (stepj), e.g., by reacting compound J with sodium ethanolate in ethanol, to provide the bicyclic compound of formula K, which in turn may be reacted with an appropriate iodination reagent under suitable reaction conditions (step k), for instance, iodine and potassium hydroxide. Compound E may then be obtained by reacting compound K with a suitable reagent bearing protecting group Y1 under appropriate reaction conditions. For instance, the compound of formula K may be reacted with p-tolyl sulfonyl chloride (TsCI) in the presence of triethylamine and DMAP to provide the compound of formula C with Y1 being p-tolylsulfonyl. Scheme C Compounds of formulas S and T, which may be useful intermediates for making bicyclic compound of formula I with X1 being N, are available via the synthetic route shown in Scheme C above. The chloro-substituted bicyclic compound of formula M is converted to the tosylated compound of formula N under similar reaction conditions described for Schemes A and B above (reaction step m). Replacing the chloro substituent by an hydroxy group is effected, for instance, by reacting the compound of formula N with K3PO4 in the presence of suitable organopalladium catalysts, e.g., Pd2dba3CHCl3 (tris-(dibenzylideneacetone)dipalladium (0) and tBuBrettPhos (2-di-tert-butylphosphin-3,6-dimethoxy-2’,4’,6’-triisopropyl-1,1’-biphenyl)-2-(2’-amino- 1,1’-biphenyl) (step n), to yield compound P. Alkylation with a suitable alkylhalide in the presence of a strong base, e.g., methyliodine and LiHMDS (lithium bis(trimethylsilyl)amide), provides the lactam derivative of formula Q (step p). Removing the p-tosyl protecting group (step q) to provide compound R and subsequently reacting with an iodination reagent like NIS (step r) provides the bicyclic compound of formula S. The alkylated lactam derivative of formula S may then be converted (step s) into the functionalized bicyclic compound of formula T by introducing a suitable protecting group Y1 under conditions similar to those described for reaction step b in Scheme A. Compound T may then be converted into a compound of formula U by replacing the iodine substituent with a suitable boronate, Y3, the introduction of which permits further transformation by C-C or C-N coupling reactions. The reagents and reaction conditions of step t may be similar to those of reaction step e in Scheme A. Scheme D Scheme D depicts a synthetic route for making certain compounds of the present invention of formula I starting from intermediate F (see Scheme A). Compound F bearing a boronate functional group Y3 is reacted in reaction step u with a compound of formula W in which A, L1, and B are as defined for formula I and Hal3 denotes Br or I, under typical reaction conditions of C-C cross-coupling reactions like the Suzuki coupling, for instance by reacting a compound of formula F with compound of formula Win the presence of sodium carbonate and Pd(dppf)Cl2-CH2Cl2 ([1,1'-Bis(diphenylphosphino)-ferrocene]palladium(ll) dichloride). Compounds of formula W are readily available either from commercial sources or by methods well-known in the art. Reaction step u provides the compound of formula Z, the protecting group Y1 of which may be cleaved of by standard methods depending on the specific nature of Y1 to yield the bicyclic compound of formula AA. If, for instance, Y1 is a p-tosyl group, it may be removed by utilizing sodium ethanolate in ethanol. Finally, compound AA is converted in reaction step w to compound CC by reacting it with the compound of formula BB, LG1-R2 wherein LG1 is a suitable leaving group and R2 is as defined for formula I hereinabove. For instance, if LG1 is a halogen selected from Cl, Br or I, then reaction step w may be a nucleophilic substitution reaction of the compound of formula AA with LG1-R2. Depending on the specific nature of LG1-R2 this reaction step w may be performed by deprotonating the NH group utilizing a suitable base such as sodium hydride or cesium carbonate and subsequent reaction of the intermediate with a suitable compound of formula BB, e.g., an alkyliodide like CH3-I, a brominated compound like Br-CH2CN, or a chlorinated compound like chloromethylimidazole hydrochloride. Substituent R2 of the compound of formula CC may further be modified to obtain further compounds of formula CC. It is to be noted that compounds of formulas AA and CC represent certain embodiments of compounds of the present invention of formula I. It should further be noted that compound of formula U may be converted into compounds of formula I with Ring D together with R2 being D-1 and X1 being N, i.e., compounds of formula l-B ( R2 ) by utilizing a reaction route similar to the one depicted in Scheme D. Alternatively, compounds of formula I may be obtained by first reacting a compound of formula E with a compound of Y3-A-L1-B, wherein A, L1, and B are as defined for formula I and Y3 is a suitable boronate moiety, under typical C-C coupling reaction conditions (as described for reaction step u in Scheme D) to provide a compound of formula Z, which is then further converted into a compound of formula AA or CC as depicted in Scheme D above. It is a further alternative to react a compound of formula L (Scheme B) instead of formula E with a compound of formula Y3-A-L1-B under similar reaction conditions which provides a compound of formula AA directly. It will be understood that a similar reaction sequence could be applied to compounds of formula S orT (Scheme C) to eventually obtain compounds of formula l-B. It should further be noted that compounds of formula I with ring D together R2 being D-2, i.e., compounds of formula l-C, are accessible from compounds of formula S in Scheme C above by performing reaction step s under suitable conditions so that besides the compound of formula T the respective regio- isomer of formula T-isomer ( is obtained and separated from its isomer of formula T by appropriate means, e.g., column chromatography. That compound T-isomer may then further be converted into the compound of formula U-isomer (                       ) under reaction conditions similar to reaction step t in Scheme C above. The compound of formula U-isomer may then be converted into compounds of formula l-C by utilizing a reaction route similar to the one depicted in Scheme D. DD Scheme E Scheme E depicts a synthetic procedure for making compounds of the present invention in which (in formula I) R3 denotes halogen: A compound of formula CC in which R2 is a suitable protecting group, e.g., a tosylate, is reacted in reaction step x with an appropriate halogenating agent under suitable reaction conditions to yield the respective halogenated compound of formula DD (with Hal being F, Cl, Br, or I). Such an appropriate halogenation reagent can be, for instance, a fluoronating reagent (Hal = F) like 1-chlormethyl-4-fluor-1,4-diazoniabicyclo[2.2.2]octan-bis(tetrafluorborat) (Selectfluor) in acetonitrile and water; or a iodinating reagent (Hal = Br) like N-iodosuccinimide (NIS) in dimethylformamide in the presence of an organic acid like trifluoroacetic acid. Reactions of compounds of formula CC with similar chlorinating or brominating reagents (like NCS or NBS) provide the respective compounds of formula DD with Hal = Cl and Br, respectively. Halogenated compounds of formula I with ring D being D-1 and X1 being N (i.e., compounds of formula l-B) and R3 being halogen can be prepared in a similar fashion starting with a compound of formula EE (with R2 being a suitable protecting group, e.g., tosylate): \ R2 EE . Likewise, compounds of formula l-C with R3 being halogen can be prepared in a similar manner starting from a compound FF of formula FF ( It is to be noted that - except for instances where it is specifically stated or the context provides for a different meaning - in general the number of a term, i.e. its singular and plural form, is used and can be read interchangeably.
