Abstract
Description
[0001] Azetidine compounds and their use in therapy
[0002] Field of the invention
[0003] The present disclosure relates to compounds that modulate the YAP / TAZ-TEAD complex, to pharmaceutical compositions containing said compounds, and to the use of said compounds as medicaments, in particular for the treatment and / or prevention of cancers and / or fibrosis related diseases.
[0004] Background
[0005] The hippo signalling pathway has key roles in organ size control and tumor suppression. Signal transduction in the hippo signalling pathway involves a core kinase cascade, leading to YAP / TAZ phosphorylation. Physiological or pathological inactivation of the hippo signalling pathway leads to dephosphorylation and nuclear accumulation of YAP and / or TAZ. Nuclear YAP / TAZ binds to transcriptional enhanced associate domains (TEADs) to mediate target gene expression. The YAP / TAZ-TEAD complex regulates organ development and amplification of oncogenic factors in many cancers (e.g., sarcoma, lung cancer, thyroid cancer, skin cancer, ovarian cancer, colorectal cancer, prostate cancer, pancreatic cancer, head and neck cancer, oesophageal cancer, kidney cancer, urogenital cancer, liver cancer, breast cancer) and in fibrosis related diseases. There is a need to find modulators of the Hippo signalling pathway useful as medicaments.
[0006] The present invention provides new compounds that disrupt the YAP / TAZ-TEAD complex. Summary of the invention

[0115] and pharmaceutically acceptable salts, enantiomers, diastereomers, tautomers, solvates, isotope substituents, polymorphs, prodrugs or metabolites thereof.
[0116] In the context of the present disclosure, the various embodiments described herein can be combined.
[0117] Pharmaceutically acceptable salts of the compounds of formula (I) include those disclosed in the Handbook of Pharmaceutical Salts: Properties, Selection and Use (P. H. Stahl and C. G. Wermuth, Weinheim / Zurich: Wiley-VCH / VHCA, 2002).
[0118] In one aspect, the present disclosure relates to enantiomers, diastereomers, tautomers, solvates, isotope substituents, polymorphs, prodrugs or metabolites of the compounds of formula (I).
[0119] As used herein, the term "prodrug" is meant to indicate a compound that is converted under physiological conditions or by solvolysis to a biologically active compound described herein. Thus, the term "prodrug" refers to a precursor of a biologically active compound that is pharmaceutically acceptable. In some embodiments, a prodrug is inactive when administered to a subject, but is converted in vivo to an active compound, for example, by hydrolysis. The prodrug compound often offers advantages of solubility, tissue compatibility or delayed release in a mammalian organism. The term "prodrug" is also meant to include any covalently bonded carriers, which release the active compound in vivo when such prodrug is administered to a mammalian subject. In some embodiments, prodrugs of an active compound, as described herein, are prepared by modifying functional groups present in the active compound in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent active compound.
[0120] As used herein, the term "solvate" refers to an aggregate of molecules comprising one or more compounds of the present disclosure and one or more solvent molecules. The solvent may be water, in which case the solvate may be a hydrate. Alternatively, the solvent may be an organic solvent. Thus, the compounds of the present disclosure may exist as hydrates, including monohydrate, dihydrate, hemihydrate, sesquihydrate, trihydrate, tetrahydrate, and the like, and as corresponding solvated forms. The disclosed compounds may be true solvates, while in other cases, the disclosed compounds may only remain in water or a mixture of water plus some solvent.
[0121] The compounds disclosed herein, or pharmaceutically acceptable salts thereof, may contain one or more chiral carbon atoms, and thus may yield enantiomers, diastereomers, and other stereoisomeric forms. Each chiral carbon atom may be defined as (R)- or (S)- based on stereochemistry. Unless stated otherwise, it is intended that all stereoisomeric forms of the compounds disclosed herein are contemplated by this disclosure. When the compounds described herein contain alkene double bonds, and unless specified otherwise, it is intended that this disclosure includes both E and Z geometric isomers (e.g., cis or trans). Likewise, all possible isomers, as well as their racemic and optically pure forms, and all tautomeric forms are also intended to be included. The term "geometric isomer" refers to E or Z geometric isomers (e.g., cis or trans) of an alkene double bond. The disclosure is intended to include all possible isomers, as well as racemates and optically pure forms thereof. The preparation of the compounds disclosed herein may select racemates, diastereomers or enantiomers as starting materials or intermediates. Optically active isomers may be prepared using chiral synthesizers or chiral reagents, or resolved using conventional techniques, such as crystallization and chiral chromatography.
[0122] Conventional techniques for preparing / separating individual isomers include chiral synthesis from suitable optically pure precursors or using chiral reagents / catalysts, separation of racemates / diastereoisomers (or racemates / diastereoisomers of salts or derivatives) using, for example, chiral high-performance liquid chromatography, chiral Supercritical Fluid chromatography (SFC) or recrystallization
[0123] As used herein, the term "stereoisomer" refers to a compound consisting of the same atom, bonded by the same bond, but having a different three-dimensional structure. The present disclosure will cover various stereoisomers and mixtures thereof.
[0124] As used herein, the term "tautomer" refers to a molecule wherein a proton shift from one atom of a molecule to another atom of the same molecule is possible. The compounds presented herein, in certain embodiments, exist as tautomers. In circumstances where tautomerization is possible, a chemical equilibrium of the tautomers will exist. The exact ratio of the tautomers depends on several factors, including physical state, temperature, solvent, and pH. All tautomeric forms of the compounds disclosed herein will also be included within the scope of the present disclosure. The present disclosure also encompasses all suitable isotopic substitutions (or isotopic variations) of the compounds of the present disclosure, or pharmaceutically acceptable salts thereof. Isotopic variations of the compounds disclosed herein, or pharmaceutically acceptable salts thereof, are defined as those in which at least one atom is replaced by an atom having the same number of atoms but different in atomic mass from that found frequently in nature. Isotopes that may be incorporated into the compounds of the present disclosure and pharmaceutically acceptable salts thereof include, but are not limited to, isotopes of H, C, N, and O, such as2H,3H,11C,13C,14C,15N,17O,18O,35S,18F,36CI, and125l. Isotopic variations of the compounds described herein, may be prepared by conventional techniques using suitable isotopic variations of suitable reagents.
[0125] As used herein, the terms "crystalline form" and "polymorph" are used interchangeably and refer to crystalline structures in which a compound (or a salt, enantiomer, diastereomer, tautomer, solvate, isotope substituent, polymorph, prodrug or metabolite) can crystallize in different crystal stacking arrangements (all having the same elemental composition). Different crystal forms generally have different X-ray diffraction patterns, infrared spectra, melting points, density hardness, crystal shape, optical and electrical properties, stability and solubility. Recrystallization solvents, crystallization rates, storage temperatures, or other factors may lead to dominance of one of the crystal forms. Polymorphs of compounds can be prepared by crystallization under different conditions.
[0126] As used herein, the term "metabolite" refers to derivatives that are also pharmacologically active resulting from the metabolic process of the parent pharmaceutical active ingredient in a subject, for example, such metabolites may result from oxidation, reduction, hydrolysis, amidation, deamidation, esterification, enzymatic cleavage, and the like of the administered compound or salt or prodrug.

[0433] In-vitro Biochemical assay The assay is based on a TR-FRET sandwich immunoassay using 6His-humanYAP60-100and ’ FLAG-AVI-HumanTEAD4217-434. TEAD4 protein was produced using a process based on Hau etal., ChemBioChem, 2013, 14(10): 1218-1225. YAP was obtained via peptide synthesis. The compounds were dissolved at 50mM in 100% DMSO and serial dilutions were made in 100% DMSO. The diluted compound solutions were incubated at the same time than 6His-humanYAP60-100(1.5nM in reaction buffer) and ’ FLAG-AVI-HumanTEAD4217434(1.5nM in reaction buffer) in white 384-well plates (Greiner) The final DMSO concentrations in the assay was 1%. The mix reaction was incubated for 120 min at room temperature. After 120 min of incubation, anti-His Europium cryptate labelled antibody and Streptavidin d2 were added to the reaction mix for 120 min more at room temperature. The plate was read with an Envision microplate reader. The data analyses were carried out by using the TR-FRET module. Two sequential measurements were carried out: at 620nm for the cryptate emission and at 665nm for the signal emitted by the d2 acceptor. The ratio of the two fluorescence intensities 665 / 620 enables the calculation of Delta F (%) which represents the relative energy transfer rate for each sample. The IC50 values were estimated by fitting the data by nonlinear fit regression (GraphPad Prism). The results are presented in Table 1.

[0438] Inhibition of malignant mesothelioma tumor cell growth
[0439] The tumor cell growth inhibitory activity of the compounds of formula (I) was evaluated in NCI-H2052 mesothelioma cell line harboring a NF2 mutation. 4,000 cells / well were plated in a 96-well black plate with clear flat bottom TC-Treated Imaging plate (Greiner Bio one #655090) in regular medium (as suggested from ATCC for each cell line) with serum, which was replaced the day after with starvation medium containing 1% serum. After one day growth in the starvation medium, cells were incubated with the compounds. The starting concentration was 30 pM and serial dilutions in DMSO and medium were performed until 0.1 pM to achieve a final DMSO concentration of 0.5%. The cells were then allowed to grow for 3 days, and then, Edll (Invitrogen, Molecular Probe) was added in each well at a final concentration of 10 pM and the cells were returned to the incubator for an additional 24h. The starvation medium was removed and 100 pl of PFA 4% containing Hoechst dye was adding in each well to fix the cells. Plates were then incubated at rt for 15 min, washed twice with PBS and the cells were permeabilized by adding 100 pL per well of triton-100 0.3%. After 20 min cells were washed with PBS and Edll detection was performed according to the instructions of the manufacturer. Image acquisition was performed using the ImageXpress Micro and analyzed using the MetaXpress software (Molecular Device). Results were expressed as a percent of inhibition (%) of the cell proliferation values obtained with 0.5% DMSO treatment alone. The cellular response was determined by fitting the concentration response curves using three parameters curve fit equation and determining the concentration that inhibited cell growth between 50% and 100%. The results are presented in Table 2.
