Description

NEW METHYLQUINAZOLINONE DERIVATIVES The present invention provides a novel compound, its preparation, pharmaceutical compositions containing it, and its use as a therapeutically active substance. The compound of the invention is a BRAF inhibitor and has paradox-breaking properties. The present invention provides in particular a novel compound of Formula (I) pq t αηη / ζζητ: / β / υιλι (l) or a pharmaceutically acceptable salt thereof. The rapidly accelerating fibrosarcoma (RAF) class of serine-threonine kinases comprises three members (ARAF, BRAF, RAF1) that form the first node of the MAPK signal transduction pathway. Despite the apparent redundancy of the three RAF isoforms in signal propagation along MEK1 and 2 phosphorylation, frequent oncogenic activation mutations are typically found only for BRAF. In particular, substitution of V600 with glutamic acid or Usine results in highly activated kinase, with consequent hyperstimulation of the MAPK pathway, independent of external stimuli (Cell. June 18, 2015; 161(7): 1681-1696). The BRAF mutant is a targetable oncogenic driver, and three BRAF inhibitors (vemurafenib, dabrafenib, and encorafenib) have reached the market to date, demonstrating efficacy in BRAFV600E-positive melanoma. However, rapid acquisition of drug resistance is almost universally observed, and the duration of therapeutic benefits from targeted therapy remains limited. Furthermore, the BRAF inhibitors developed revealed the unexpected and paradoxical ability to repress MAPK signaling in BRAFV600E-driven tumors, while the same inhibitors exhibited MAPK-stimulatory activities in wild-type (WT) BRAF models (N Engl J Med 2012; 366:271-273; and British Journal of Cancer, Volume 111, Pages 640-645(2014)). Mechanistic studies on the RAF paradox then clarified that oncogenic BRAFV600E phosphorylates MEK 1 / 2 in its cytosolic monomeric form, whereas activation of WT BRAF and RAF1 requires a complex stage of events including cell membrane translocation and homo- and / or heterodimerization promoted by activated RAS (KRAS, NRAS, HRAS) (Nature Reviews Cancer, Volume 14, Pages 455-467(2014)). The binding of inhibitors such as vemurafenib, dabrafenib, or encorafenib to a wild-type BRAF or RAF1 promoter rapidly induces RAF homo- and / or heterodimerization and membrane association of the newly formed RAF dimer. In the dimeric conformation, one RAF promoter allosterically induces conformational changes in the second, resulting in an active kinase state and, importantly, a conformation unfavorable for inhibitor binding. The drug-induced dimer then promotes MEK phosphorylation via catalysis operated by the unbound promoter, leading to hyperactivation of the pathway. The RAF paradox results in two clinically relevant consequences: 1) accelerated growth of secondary tumors following BRAFi monotherapy (primarily keratoacanthoma and squamous cell carcinomas) (N Engl J Med 2012; 366:271-273) and 2) the acquisition of drug resistance in the context of BRAFi monotherapy, as well as in BRAFi+MEKi combinations, exhibits dimer-mediated RAF signaling activation by genetically driven events including RAS mutations, BRAF amplifications, and the expression of dimeric BRAF splicing variants (Nature Reviews Cancer, Volume 14, Pages 455-467 (2014)). Therefore, there is a need for RAF inhibitors capable of overcoming this paradox. Furthermore, the currently approved classic BRAF inhibitors, Vemurafenib (Mol. Pharmaceutics 2012, 9, 11, 3236-3245), Dabrafenib (J. Pharmacol Ex Ther 2013, 344(3)655-664), and Encorafenib (Pharmacol. Res. 2018;129:414-423), have very poor permeability in the brain. This is a major limitation for the use of these classic BRAF inhibitors in the treatment of brain cancer or brain metastases. Therefore, there is a need for BRAF inhibitors with improved permeability in the brain. The present invention relates to the surprising finding that the BRAF inhibitor of Formula (I) is a more potent and selective BRAF inhibitor that exhibits considerably less paradoxical activation of the MAPK signal transduction pathway while still maintaining high potency. Therefore, this compound may be termed a paradox breaker or RAF paradox breaker, as distinct from compounds that induce the RAF paradox (and which could be termed paradox inducers or RAF paradox inducers). In addition to being a paradox breaker, the compound of Formula (I) also has very potent brain penetration properties, providing an urgently needed alternative treatment for certain types of brain cancer. BRIEF DESCRIPTION OF THE FIGURES: Figure 1 discloses the P-ERK inhibition curve induced by example 1 in the BRAFA375 mutant cell line. Figure 2 discloses the P-ERK inhibition curve induced by example 2 in the BRAFA375 mutant cell line. Figure 3 discloses the P-ERK inhibition curve induced by the reference compound AR-25 in the BRAF A375 mutant cell line. Figure 4 discloses the P-ERK activation curve induced by example 1 in the BRAF WT HCT-116 cell line. For comparative purposes, data generated by treatment with the control compounds dabrafenib (paradox inducer) and PLX-8394 (paradox breaker) are also shown. Figure 5 discloses the P-ERK activation curve induced by example 2 in the BRAF WT HCT-116 cell line. For comparative purposes, data generated by treatment with the control compounds dabrafenib (paradox inducer) and PLX-8394 (paradox breaker) are also shown. Figure 6 discloses the P-ERK activation curve induced by the reference compound AR-25 in the BRAF WT HCT-116 cell line. For comparative purposes, data generated by treatment with the control compounds dabrafenib (paradox inducer) and PLX-8394 (paradox breaker) are also shown. Figure 7 illustrates the paradoxical activation of the MAP kinase pathway induced by first-generation BRAF inhibitors. BRAF is part of the first node of the MAP kinase signal transduction pathway, and mutant BRAF is an oncogenic driver (left). In tumors with the BRAF V600E / K mutation, BRAF is signaled as a monomer, a condition in which first-generation BRAF inhibitors inhibit the protein (center). First-generation BRAF inhibitors promote homo- and / or heterodimerization of BRAF WT (top right). In this context, the promoter not occupied by the BRAF inhibitor adopts a conformation unfavorable for inhibitor binding (center right). The result of treatment with a first-generation BRAF inhibitor, in this context, is paradoxically increased MAPK activation and subsequent tumor growth in BRAF WT cells (bottom right). Figure 8 discloses that Example 1 of the compound produced dose-dependent antitumor activity starting at 1 mg / kg per day, which is evidence of potent permeability-mediated efficacy in the brain. WO2012 / 118492 discloses reference compounds AR-25 as example 25, AR-30 as example 30, and AR-31 as example 31. ρρ / αηη / ζζηζ / Ε / γίΛΐ ro t αηη / ζζητvb / υιλι Ν AR-25 AR-30 AR-31 The term "pharmaceutically acceptable salt" refers to those salts of the compound of Formula (I) that retain the biological efficacy and properties of the free bases or free acids, and are not undesirable either biologically or otherwise.

Another embodiment of the present invention is the compound of Formula (I) as described herein, when prepared according to any of the processes described. Test procedures Materials DMEM medium without phenol red supplemented with L-glutamine from Thermo Fisher Scientific was purchased. Fetal bovine serum (FBS) was purchased from VWR. Advanced ERK phospho-T202 / Y204 kit: 10,000 tests were purchased from Cisbio, cat. no. 64AERPEH. A375 and HCT116 cells were obtained originally from ATCC and stored by the Roche depot. Greiner Bio-One 384-well microplates (with lid, HÍBase, low volume, cat. 784-080) were purchased. HTRF assay for the determination of P-ERK in A375 or HCT116 cells A375 is a cell-linked cancer model expressing the V600E-mutant BRAF, and HCT116 is a cell-linked cancer model expressing wild-type BRAF. First-generation BRAF inhibitors, such as dabrafenib, induce a paradoxical effect on tumor cells, inhibiting the growth of V600E-mutant BRAF cells (such as A375) while simultaneously activating the growth of wild-type BRAF cells (such as HCT116). ERK1.2 phosphorylation (the terminal member of the MAPK pathway phosphorylation cascade) is reported hereafter as the primary readout of MAPK pathway activation status. Prior to the assay, the A375 and HCT116 cell lines are maintained in phenol red-free DMEM medium supplemented with 10% fetal bovine serum (FBS).Following treatment with the compound, P-ERK levels are determined by measuring the FRET fluorescence signal induced by the selective binding of 2 antibodies provided in the aforementioned kit (Cisbio, Cat. No. 64AERPEH) to ERK protein when phosphorylated at Thr202 / Tyr204. Briefly, 8000 cells / cavity in 12 pL of medium / cavity are placed in the 384-cavity plate and left overnight in the incubator (at 37°C with a humidified atmosphere containing 5% CO2). The next day, the plate is treated in duplicate with the test compounds, dabrafenib and PLX8394 (the latter two as controls) at the following final drug concentrations: 10 μM-3 μM-1 μM-0.3 μM-0.1 μM-0.03 μM-0.01 μM-0.003 μM-0.001 μM. All cavities are normalized with DMSO and the drug is incubated for 1 hour.Next, 4 μI of a 4X lysis buffer provided with the kit is added to the cavities, and then the plate is centrifuged for 30 seconds (300 rcf) and incubated on a plate shaker for 1 h RT (room temperature). ro t αηη / ζζητve / υιλι At the end of the incubation, 4 µl / cavity of advanced anti-P-ERK antibody solution (prepared according to the manufacturer's instructions) and then 4 pl / cavity of cryptoate anti-PERK antibody solution (prepared according to the manufacturer's instructions) (Cisbio, Cat. No. 64AERPEH) are added to the test cavities. To allow for proper data normalization, each plate always includes (according to the manufacturer's instructions) drug-free control cavities, as indicated in the following table: ρρ / αηη / ζζηζ / Ε / γίΛΐ p-ERK HTRF cavity compositions (μI): Ctrl neg Ctrl pos Ctrl neut cpd blank - - 12 12 12 Cells 12 - - - - Medium - - - <0.05 - Cpd - 16 - - - Control lysate (ready to use) 4 - 4 4 4 Lysis buffer 4x 4 4 4 4 - Advanced p-ERK antibody solution - - - - 4 Advanced p-ERK1 / 2 cryptate antibody solution 20 20 20 20 20 Total volume in cavity The plate is then centrifuged at 300 rcf for 30 seconds, sealed to prevent evaporation, and incubated overnight in darkness at room temperature. Next, the plate is analyzed and the fluorescence emission value is obtained using a Pherasstat FSX apparatus (BMG Labtech) at 665 and 620 nM. The fluorescence values ​​obtained are processed according to the formula Ratio=Signal(620nm) / Signal(625nm)*10000, and then the average ratio in the blank is subtracted from all the values. Data were normalized for A375 cells (BRAF inhibition) by considering the average ratio (with blank subtraction) from cells treated with DMSO alone as 100% and the average ratio (with blank subtraction) from cells treated with Dabrafenib 10 µM as 0%. The mean of the normalized points was fitted with a sigmoidal curve, and the IC50 was determined. The results are shown in Tables 1-2 and Figures 1-3. Data are normalized for HCT116 cells (BRAF activation) by considering the average ratio (with blank subtraction) from cells treated with DMSO alone as 0% and the average ratio (with blank subtraction) from cells treated with dabrafenib at the concentration that provides the highest signal as 100%. Individual points are fitted with sigmoidal or bell curves, and the percentage of activation is determined relative to the maximum activation mediated by dabrafenib. The EC50 is the concentration at which activation equals 50% of the maximum activation achieved with dabrafenib. The results are shown in Table 2 and Figures 4-6. If the activation does not reach 50% of the maximum activation achieved with dabrafenib, then the EC50 calculation is not applicable. The percentage of maximum paradox induction effect of dabrafenib is determined by evaluating the percentage at which the test compound induces its maximum P-ERK signal as a percentage of the highest signal produced by dabrafenib within the evaluated dose range. pq t αηη / ζζητvb / υιλι Ex- Kd (μΜ) BRAF BRAF V600E CRAF CSK LCK 1 0.0006 0.0012 0.0017 23.3 40 2 0.0013 0.0009 0.0012 9.16 20.12 AR-25 0.0001 0.0002 0.0003 >40 >40 AR-30 0.1740 0.5040 0.8220 8.007 10.352 AR-31 0.0459 0.1190 0.1903 1.208 11.975 Table 1: Example 1 and Example 2 have high affinity for RAF kinases and high selectivity on C-terminal Src kinase (CSK) and lymphocyte-specific tyrosine protein kinase (LCK), compared to AR-30 and AR-31.
