[0003] Substituted bicyclic compounds
[0004] Field of the invention
[0005] The present invention relates to bicyclic compound. These bicyclic compounds are useful as TEAD binders and / or inhibitors of YAP-TEAD and 5 TAZ-TEAD protein-protein interaction or binding and for the prevention and / or treatment of cancer and other severe disorders and diseases.
[0006] Background of the invention
[0007] In recent years the Hippo pathway has become a target of interest for the 10 treatment of hyperproliferative disorders and diseases, in particular cancer (S. A. Smith et al., J. Med. Chem. 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.
[0008] Furthermore, as the Hippo pathway plays a role in several biological processes - like in self-renewal and differentiation of stem cells and 20 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)).
[0009] 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 30 co-activators, YAP (Yes-associated protein) and TAZ (Transcription coactivator with PDZ binding motif). Phosphorylation of YAP / TAZ leads to their sequestration in the cytoplasm and eventually to their degradation. InForeignfiling text P25-006-SEC-W001
[0010] 2
[0011] 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 5 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.
[0012] 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).
[0013] 15
[0014] 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 20 Cancer, 4, 812-828 (2023); WO 2021 / 108483 A1).
[0015] 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.
[0016] 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 30 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.Foreignfiling text P25-006-SEC-W001

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 10 one of the rings of that heterocycle is a saturated or unsaturated but non- aromatic heterocycle that is fused with at least one aromatic or heteroaromatic ring system.

[0334] The term “unsaturated”, as used herein, means that a moiety or group or 5 substituent has one or more units of unsaturation.
[0335] 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 10 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.

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., 5 diethyl etherate.
[0363] 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.
[0364] 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, 15 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, 20 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 30 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%.Foreignfiling text P25-006-SEC-W001
[0365] 47
[0366] 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 5 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 10 an optically active reagent such as, for example, an optically active alcohol, and subsequent elimination of the radical.
[0367] 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 20 and the like.
[0368] 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.
[0369] The term "pharmaceutically acceptable salts" refers to salts prepared from 30 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 inventionForeignfiling text P25-006-SEC-W001
[0370] 48
[0371] 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, 5 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 10 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 20 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, embonicacid, 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, 30 hydrobromides, bromides, iodides, sulfates, phosphates, methanesulfonates (mesylates), tosylates, carbonates, bicarbonates, formates, acetates, sulfoacetates, triflates, oxalates, malonates, maleates, succinates, tartrates,Foreignfiling text P25-006-SEC-W001
[0372] 49
[0373] 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 nonintegral multiple of one.
[0374] 5
[0375] 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- 10 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.
[0376] 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 20 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.
[0377] 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;
[0378] 30 (b) pharmaceutically acceptable salts of the compounds and of the items mentioned under (a);Foreignfiling text P25-006-SEC-W001
[0379] 50
[0380] (c) pharmaceutically acceptable solvates of the compounds and of the items mentioned under (a) and (b);
[0381] (d) N-oxides of the compounds and of the items mentioned under (a), (b), and (c).
[0382] 5
[0383] 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.
[0384] 10
[0385] 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, 20 phosphorus, sulfur, fluorine and chlorine, for example2H (D),3H,13C,14C,
[0386] 15N,18O,17O,31P,32P,33S,34S,35S,36S,18F and36CI, 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 isotopelabelled 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 as3H or14C, 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 30 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 metabolic stability of thisForeignfiling text P25-006-SEC-W001
[0387] 51
[0388] 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 5 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.
[0389] 10 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 20 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 kivi / kD = 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.
[0390] 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 30 with poor pharmacokinetic profiles are susceptible to oxidative metabolism.
[0391] In vitro liver microsomal assays currently available provide valuable information on the course of oxidative metabolism of this type, which in turnForeignfiling text P25-006-SEC-W001
[0392] 52
[0393] 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 5 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.
[0394] 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 15 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 deuteriumhydrogen exchange of this type.
[0395] 20
[0396] 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 carbon-hydrogen (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.

[0401] Furthermore, the present invention relates to pharmaceutical compositions 5 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.
[0402] 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.
[0403] 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 severity 30 of the conditions being treated and on the nature of the active ingredient.
[0404] They may be conveniently presented in unit dosage form and prepared by any of the methods well-known in the art of pharmacy.Foreignfiling text P25-006-SEC-W001
[0405] 54
[0406] 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 5 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 10 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 20 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 30 ingredients, in addition to a compound of the invention.Foreignfiling text P25-006-SEC-W001
[0407] 55
[0408] 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 5 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 15 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.
[0409] 20 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 30 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,Foreignfiling text P25-006-SEC-W001
[0410] 56
[0411] suppression and / or amelioration of non-cancerous disorders and diseases, e.g. cardiovascular diseases and fibrosis (like liver fibrosis).

[0415] Still another particular embodiment of the invention is the use of a compound of the present invention - or N-oxides, prodrugs, solvates, tautomers or 20 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.
[0416] Preferably, the present invention relates to a compound of the present 30 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 ;Foreignfiling text P25-006-SEC-W001
[0417] 57
[0418] 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 5 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.
[0419] The disclosed compounds of the present invention and in particular of formula I can be administered in combination with other known therapeutic agents, including anticancer agents. As used here, the term "anticancer agent" relates to any agent which is administered to a patient with cancer for the purposes of treating the cancer. The anti-cancer treatment defined above may be applied as a monotherapy or may involve, in addition to the herein disclosed compounds of the present invention, conventional surgery or radiotherapy or medicinal therapy.

Unless specifically defined in a different manner, R1, R2, A, L1, and B are defined as for the compounds of formula I hereinabove or below. The substituted 5-azaindole (or 1 H-pyrrolo[3,2-c]pyridine) of formula A is either available from a commercial source or readibly available by utilizing synthetic methods and procedures well-known to the skilled person. In reaction step (a) the bicyclic compound of formula A is reacted with an iodination reagent under suitable reaction condition, for instance, iodo-succinimide (NIS; 1-iodopyrrolidinone- 2, 5-dione) in DMF, to provide the iodinated compound of formula B. Subsequently, in reaction step (b) the compound of formula B is reacted under appropriate reaction conditions with a suitable reagent for introducing a suitable protecting group, Y1, on the nitrogen ring atom in position 5 of the bicyclic ring system, to yield the compound of formula C. A suitable protecting group Y1may be any protecting group, PG1, that substantially protects this 30
[0556] nitrogen ring atom in 5-position from reacting with any of the reagents and substances utilized in the following reaction step (c). Examples for suchForeignfiling text P25-006-SEC-W001
[0557] 73
[0558] suitable protecting groups are tert.-butyl carboxylate (-C(=O)-O-tert.-butyl), which may be introduced by reacting the compound of formula B with, e.g., di-tert.-butyl carbonate in the presence of catalytic amounts of DMAP (4- dimethylaminopyridine); or (trimethylsilyl)ethoxy-methyl (-CH2-O-(CH2)2- 5 Si(CH3)3), which may be introduced by reacting the compound of formula B with, e.g., [2-(chloromethoxy)ethyl]trimethylsilane in the presence of sodium hydride (NaH); or tosylate (p-methylphenylsulfonyl) which may be introduced by reacting the compound of formula B with, e.g., tosylchloride in the presence of NaH. In reaction (c) the compound of formula C is reacted in a C-C cross-coupling reaction, for instance a Suzuki coupling, with the compound of formula D, wherein A, L1, and B have the same meaning as for compounds of formula I and Y2is a boronate functional group (e.g., -B(OH)2 or a suitable ester thereof). The boronic acid or boronic acid ester derivative of formula D is readily available, e.g., from the respective chloro-substituted 15 compound of formula D (Y2= Cl) by methods well-known in the art; for instance, by utilizing trimethyl borate in the presence of a strong base like phenyl lithium and subsequent hydrolysis of the boronic acid ester to yield the boronic acid (Y2= -B(OH)2) or by utilizing 4,4,5,5-tetramethyl-1 ,3,2- dioxaborolan in the presensence of potassium acetate and chloro(2- 20 dicyclohexylphosphino-2',4',6'-triisopropyl-1 , 1 '-biphenyl)[2-(2'-am ino-1 , 1 '- biphenyl)]palladium(ll) (XphosPd G2) as a palladium(ll)-catalyst to provide

Reaction step (c) is performed under typical reaction conditions of C-C cross-coupling reactions like the Suzuki coupling, for instance by reacting compound of formula C with compound of formula D in the presence of potassium carbonate and 1,1'- bis(diphenylphosphino)ferrocene palladium or 4-[bis(2-methyl-2- propanyl)phosphino]-N,N-dimethylaniline-dichloropalladium
[0561] 30 (Pd(amphos)2Cl2). Removing the protecting group, Y1, from the compound of formula E in reaction step (d) under either acidic (e.g., trifluoro acetic acid, TFA) or basic conditions (e.g., sodium hydroxide) depending on the nature ofForeignfiling text P25-006-SEC-W001
[0562] 74
[0563] the specific protecting group yields the compound of formula F, which can also be described as a compound of formula I with R2being H. Finally, compounds of formula I with a substituent R2other than H, i.e. , compounds of formula H in Scheme A are available by reacting a compound of formula F 5 with an appropriate compound of formula G, LG1-R2with LG1being a suitable leaving group and R2being as defined for formula I (except for H) (reaction step (e)). For instance, if LG1is a halogen selected from Cl, Br or I, then reaction step (e) may be nucleophilic substitution reaction of the compound of formula F with LG1-R2. Depending on the specific nature of LG1-R2this reaction step (e) 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 G, e.g., a alkyliodide like CH3-I, a brominated compound like Br-CFhCN, or a chlorinated compound like chloromethylimidazole hydrochloride. Substituent R2of the compound of formula H may further be modified to obtain further compounds of formula H.

Reaction conditions of step (g) may be the same or similar to the reaction conditions of step (c) in Scheme A. The compound of formula L may then be reacted under appropriate reaction conditions 20
[0574] (utilizing, e.g., cesium carbonate or NaH in DMF) with a compound of formula M, wherein B is as defined for formula I and Y3denotes LG2-CH2- with LG2being a suitable leaving group, such as a alkyl-SOs group (alkylsulfonate), which provides a compound of formula E-1 with L1denoting a divalent -0- CH2- radical. Alternatively, if L1denotes -O-, then Y3may be another suitable leaving group, LG3, such as fluorine (F). The compound of formula E-1 may then be subjected to the reactions steps (d) and optionally (c) as described for Scheme A above to provide compounds of formula F and H, respectively, with L1denoting a divalent -O-CH2-radical and -0- radical, respectively.

[0583] first a strong base, like NaH is added and then p-tolylsulfonylchloride to provide the compound of formula N-CI (reaction step (j)) (with Ts representing a tosylate group), which in turn is reacted with hydriotic acid (HI) in the presence of sodium iodide (Nal) to yield the compound of formula N-l (reaction step (k)). In subsequent reaction step (m) compound N-l is reacted with methyl 2,2-difluoro-2-(fluorosulfonyl)acetate (compound 0) in the presence of copper(l)-iodide to provide the compound of formula N-CF3. After the (optional) removal of the tosylate protecting group under basic conditions (e.g., sodium hydroxide) the compound of formula A-CF3 is obtained which may further be used to prepare compounds of the present 30

[0936] 5 Biological Data
[0937] SK-HEP-1 reporter assay (“reporter assay”)
[0938] To identify inhibitors of YAP-TEAD interaction, 8x TEAD responsive elements driving the NanoLuc® luciferase gene were stably integrated into SK-HEP-1 cells (ECACC #: 91091816).
[0939] For the assay, cells were treated in duplicates with the test compounds in a 10-point dose, with the top concentration starting at 30 pM (final concentration in assay). After a 24 hours incubation at 37 °C, 95 % rH, and 5 % CO2, a luciferase substrate I lysis reagent mix (NanoGio™, Promega) was 15 added to the cells, allowing the quantification of cellular luciferase activity.
[0940] Cell Media: The cells were cultured in the following media: MEM, +10 % FBS, +1x GlutaMAX, +1mM Sodium-Pyruvate, + 100 pM Non-essential amino acids, +0.1mg / ml Hygromycin. The media used for the assay was: MEM (w / o 20 Phenol Red), +10 % FBS, +1x GlutaMAX, +1mM Sodium-Pyruvate, + 100 pM Non-essential amino acids, +0.5 % Pen / Strep
[0941] Reagents: The reagents used are listed below:

[0948] Cell culture: The cells were examined using an inverted microscope to check for health and cell density. To dissociate adherent cells, the monolayer of cells was washed once with pre-warmed PBS. After removing the PBS, 3 mL pre-warmed Accutase® was added to a F75 flask, dispersed evenly and the flask was allowed to sit in incubator for ~4-5 minutes.
[0949] When a single cell suspension was obtained, 7 ml of prewarmed growth media was added and resuspended with the cells. The cell suspension was transferred to a sterile 15 ml conical centrifuge tube, and spun for 5 min at 300xg, RT. The supernatant was discarded and the pellet was resuspended in 10 ml of pre-warmed growth media.
[0950] The total cell count was determined, and 20 pL of the desired cell number was added to each well of a 384 well plate using a Multidrop Combi. The plates were then incubated for 24 hours at 37 °C, 95 % rH, and 5 % CO2.
[0951] Compound treatment: 24 hours after seeding, the cells were treated with compounds.
[0952] A 1:333 dilution of compounds, diluted in DMSO, was made to get a final concentration of 0.3 % DMSO per well. To transfer the compounds to the assay plate, 120 nL was shot from Labcyte low dead volume plates to the cell plates containing 20 pL media / well with the ECHO 555 liquid handling system.
[0953] After treatment, the cells were fed with 20 pL fresh pre-warmed assay media using a Multidrop combi.
[0954] The assay plates were then incubated for another 24 hours at 37 °C, 95 % 30 rH, and 5 % CO2.Foreignfiling text P25-006-SEC-W001
[0955] 128
[0956] Luciferase readout: 24 h after treatment, the plates were taken out of the incubator and were allowed to equilibrate to RT. 30 pL of NanoGio® reagent was added to the plates in the dark. Plates were shaken for 20 min on a Teleshake (~1500 rpm) in the dark. The luminescence was then measured 5 using an EnVision microplate reader. The ICso values were generated using Genedata Screener®.
[0957] Viability assay in H226 (Yap-dependent) and SW620 Yap KO (Yap independent) cells
[0958] The ability of YAP-TEAD inhibitors to inhibit tumor cell growth was evaluated using two different cell lines: NCI-H226, which is a YAP dependent cell line, and SW620 cells, where YAP and TAZ were knocked out using CRISPR to generate a YAP independent cell line.
[0959] For the assay, cells were treated in duplicates with the test compounds in a 10-point dose, 1:3 dilution steps, with the top concentration starting at 30 pM (final concentration in assay). After a 96 hours incubation at 37 °C, 95 % rH, and 5 % CO2, a cell-permeant DNA-binding dye that stains only healthy cells (CyQUANT®, Promega) was added to the cells, allowing the quantification of cell viability.
[0960] Cell Media: The NCI-H226 cells were cultured in the following media: RPMI 1640, +10 % FBS, +1x GlutaMAX, +10 mM HEPES, + 0.5 % Pen / Strep. The SW620-KO cells were cultured in the following media: DMEM / F-12, +10 % FBS, +1x GlutaMAX, +10 mM HEPES, +0.5 % Pen / Strep.

[0977] CvQuant® Measurement
[0978] 96 hours after treatment 30 pL of CyQuant® reagent was added to the assay plates using a Multidrop combi in the dark. The plates were then incubated 5 for 1 hour at 37 °C, 95 % rH and 5 % CO2. Thereafter, the assay plates were removed from the incubator and allowed to equilibrate to RT for 30 min in the dark without lid. Finally, they were measured using an EnVision microplate reader with a FITC bottom read program.

[1021] Nano Differential Scanning Fluorimetry. NanoDSF was performed on a Prometheus NT.48 instrument (NanoTemper Technologies GmbH). Protein sample was briefly centrifuged before preparation. The final reaction mixture contained 11.8 pM of hsTEADI (209-426), 7.3 pM of hsTEAD2 (217-447)- His, 7.9 pM of hsTEAD3 (216-435) or 11.7 pM of hsTEAD4 (217-434)-Thrb- His diluted in 20 mM Tris pH 8.0, 150 mM NaCI, 0.5 mM TCEP to which 1 pL DMSO 100 % (apo) or 100 pM of each compound were added. This incubation was performed at 4 °C for 2 hours. High sensitivity capillaries (NanoTemper Technologies) were filled with 10 pL of sample and placed on the Prometheus NT.48 sample holder. A temperature gradient of 1°C / min was applied from 25 °C to 90 °C. The intrinsic protein fluorescence at 330 and 350 nm and light scattering were recorded. Data were analysed with respect to the fluorescence (330 nm) and / or aggregation values. The melting temperatures (Tm) were obtained by calculating the midpoint of each 30
[1022] transition, using the PR.ThermControl Software™ version 2.16 and Stability Analysis Software™ version 1.1. The thermal stability and aggregation effect of each compound was calculated by subtracting the Tm values in theForeignfiling text P25-006-SEC-W001
