Description

[Technical Field]

[0001] background The MAPK / ERK signaling pathway transmits extracellular stimuli to the nucleus, thereby regulating a variety of cellular responses, including cell proliferation, differentiation, and apoptosis. The KRas protein initiates the MAPK / ERK signaling pathway and functions as a switch involved in inducing cell division. In its inactive state, KRas binds to guanosine diphosphate (GDP), effectively sending a negative signal that suppresses cell division. In response to extracellular signals, KRas is allosterically activated, enabling nucleotide exchange between GDP and guanosine triphosphate (GTP). In its GTP-bound active state, KRas recruits and activates proteins necessary for the propagation of growth factor-induced signaling, as well as other cellular signaling receptors. Examples of proteins recruited by KRas-GTP include c-Raf and PI3 kinase. As a GTPase, KRas converts bound GTP back to GDP, thereby deactivating itself and again transmitting signals to suppress cell division. KRas gain-of-function mutations exhibit increased GTP binding and decreased ability to convert GTP to GDP. As a result, MAPK / ERK signaling, which promotes the proliferation of cancer cells, increases. Missense mutations in KRas at codon 12 are the most common and significantly reduce GTPase activity.

[0002] Oncogenic KRas mutations have been identified in approximately 30% of human cancers and have been demonstrated to activate multiple downstream signaling pathways. Despite the prevalence of KRas mutations, they remain a challenging therapeutic target. (Cox, ADDrugging the Undruggable RAS: Mission Possible? Nat. Rev. Drug Disc. 2014, 13, 828-851; Pylayeva-Gupta, y et al. RAS Oncogenes: Weaving a Tumorigenic Web. Nat. Rev. Cancer 2011, 11, 761-774).

[0003] To date, research has focused on KRas G12C variant inhibitors (for example, International Publication Nos. 2019 / 099524, 2020 / 081282, 2020 / 101736, 2020 / 146613, and 2021 / 118877 disclose KRas G12C inhibitors), while International Publication No. 2021 / 041671 discloses KRas G12D small molecule inhibitors, and International Publication No. 2017 / 011920 discloses KRas G12C, G12D, and G12V small molecule inhibitors.

[0004] There remains a need to provide alternative small molecule KRas inhibitors. Specifically, there is a need to provide more potent, orally deliverable KRas inhibitors useful for the treatment of cancer. More specifically, there is a need to provide small molecule inhibitors that specifically inhibit KRas GTP activity. There is also a need to provide small molecule KRas inhibitors that exhibit higher efficacy with the same or reduced KRas inhibitory activity. Furthermore, there is a demand for KRas inhibitors that exhibit better pharmacokinetic / pharmacodynamic properties. There is also a need to provide more potent KRas inhibitors that exhibit increased efficacy with reduced or minimized adverse or undesirable effects. Furthermore, there is a need to provide more potent KRas inhibitors that exhibit selective inhibitory preference for KRas G12C, G12D, and / or G12V variants than HRAS or NRAS. The present invention addresses one or more of these needs by providing a novel KRas inhibitor. [Overview of the Initiative]

[0198] Individual isomers, enantiomers, diastereomers, and atropisomers can be separated or divided at any convenient point in the synthesis of the compounds listed below by selective crystallization techniques or chiral chromatography, etc. (see, for example, J. Jacques, et al., "Enantiomers, Racemates, and Resolutions," John Wiley and Sons, Inc., 1981, and ELEliel and SHWilen, "Stereochemistry of Organic Compounds," Wiley-Interscience, 1994). The molecules described herein include compounds that are atropisomers and may exist in different conformations or as different rotational isomers. Atropisomers are compounds that exist in different conformations resulting from restricted rotation around a single bond. Atropisomers can be isolated as distinct chemical species if the energy barrier to rotation around the single bond is sufficiently high and the interconversion rate is sufficiently slow to separate the individual rotational isomers from each other. This specification is intended to include all isomers, enantiomers, diastereomers, and atropisomers that are possible with or can be produced using the compounds disclosed herein. In the molecules described herein, only those molecules for which the absolute conformation (or atropisomer conformation) of the chiral center is known use the nomenclature rules or chemical formulas depicted to indicate chirality or atropisomerism. Those skilled in the art will readily understand and identify when other chiral centers are present in the molecules described herein.

[0199] Any compound of formula I that can chemically form a salt can be readily converted to a pharmaceutically acceptable salt and isolated as such. Salt formation can occur upon addition of a pharmaceutically acceptable acid to form an acid addition salt. Salts can also be formed simultaneously upon deprotection of nitrogen or oxygen, i.e., upon removal of a protecting group. Examples of reactions and conditions for salt formation can be found in Gould, PL, "Salt selection for basic drugs," International Journal of Pharmaceutics, 33:201-217 (1986), Bastin, RJ, et al., "Salt Selection and Optimization Procedures for Pharmaceutical New Chemical Entities," Organic Process Research and Development, 4:427-435 (2000), and Berge, SM, et al., "Pharmaceutical Salts," Journal of Pharmaceutical Sciences, 66:1-19 (1977).

[0450] Biological assays The following assays demonstrate that the exemplified compounds are potent inhibitors of KRas G12C, G12D, and / or G12V, inhibiting the growth of certain tumors in vitro and / or in vivo.

[0451] Cellular Phospho-ERK AlphaLISA® assay for KRAS inhibition The objective of these assays was to quantify the ability of test compounds to selectively inhibit KRAS signaling in cells exhibiting KRAS amplification and expressing activated KRAS G12 mutations (Table 14). Cancer cell lines used in this study were selected based on the presence of homozygous activated KRAS G12 mutations or KRAS gene amplification. In addition, these assays were performed on a set of RAS-free mouse embryonic fibroblasts (MEFs) manipulated to express only KRAS wild-type, HRAS, and NRAS, respectively (Table 14). KRAS selectivity of test compounds was confirmed using MEF cells.

[0452] Table 14: Cell line information [Table 18]

[0453] The activity of the compound is determined by measuring the change in phosphorylation levels of the downstream effectors, extracellular signal-regulated kinases 1 and 2 (ERK1 / 2), in cells treated with the compound. The phosphorylation level of ERK-1 / 2 is measured using the AlphaLISA® SureFire® Ultra® p-ERK1 / 2(Thr202 / Tyr204) assay kit (number ALSU-PERK-A50K, PerkinElmer® Waltham, MA). The AlphaLISA® assay is a quantitative sandwich immunoassay that can be used to detect phosphorylation of target proteins from cell lysates using bead-based alpha technology. This assay kit contains two antibodies, one of which binds to the phosphorus-Thr202 / Tyr204 epitope on ERK-1 / 2, and the other which recognizes distinct sites on the protein. One of these antibodies is biotinylated and conjugated to streptavidin-coated Alpha donor beads, while the other antibody is conjugated to AlphaLISA® acceptor beads. The donor and acceptor beads are brought close together during phosphorylation of ERK-1 / 2 in cell lysates. When the donor beads are excited with 600 nm wavelength light, the photosensitizer within the beads converts ambient oxygen to an excited singlet state. If the acceptor beads are within 200 nm of this reaction, the singlet oxygen reacts with the acceptor, resulting in chemiluminescence emission. The amount of light measured is proportional to the amount of phosphorylated ERK-1 / 2 in the lysate. The AlphaLISA®, SureFire®, and Ultra® p-ERK 1 / 2 (Thr202 / Tyr204) assay kit includes AlphaLISA® antibody conjugate donor beads and acceptor beads, lysis buffer concentrate, and a set of proprietary buffers (activation buffer, reaction buffer 1, reaction buffer 2, and dilution buffer).

[0454] To perform these assays, the test compounds and controls were acoustically dispensed into a white 384-well assay plate (Proxiplate-384, PerkinElmer No. 6008280) in a 10-point 3-fold dilution series in 30 nL of DMSO (Labcyte ECHO®, San Jose, CA). Cells were then added to the assay plate (HBSS, Sigma No. 55021C, 10% FBS, GIBCO No. 10082-147) in 8 μL / well of assay medium at cell line-specific densities (Table 14). In each well, the final compound concentration ranged from 0.5 to 10,000 nM, and the final DMSO concentration was 0.375%. The maximum signal control well contained only 0.375% DMSO (negative control), and the minimum signal control well contained 10,000 nM of the control compound (positive control). Cells in suspension are incubated with the test compound and reference compound at 37°C / 5% CO2 for 2 hours. After 2 hours of incubation, cells are lysed by adding 2 μL of AlphaLISA® lysis buffer concentrate (5-fold) supplemented with a protease / phosphatase inhibitor cocktail (Thermo Scientific No. 78442). The assay plate is covered with an opaque lid and shaken at 750 rpm for 30 minutes at room temperature on a multi-plate shaker (Heidolph, Schwabach, Germany) to induce cell lysis. During lysis, AlphaLISA® acceptor beads are diluted 1:50 in the prepared buffer mixture (1:1 AlphaLISA® reaction buffers 1 and 2 and 1:25 dilution of AlphaLISA® activation buffer). After cell lysis, the plate is briefly centrifuged and 5 μL / well of the prepared acceptor beads is added. The plate is then covered and incubated in the dark at room temperature for 2 hours. During the incubation of the acceptor beads, the donor beads are prepared by diluting Alpha streptavidin donor beads in AlphaLISA® dilution buffer at a ratio of 1:50. After incubation of the acceptor beads, 5 μL / well of the donor bead mixture is added to the plate. The plate is then covered and incubated in the dark at room temperature for 2 hours.After this incubation period, the AlphaLISA signal is read using a PHERAstar® FSX multimode plate reader (BMG Labtech, Ortenberg, Germany) equipped with an AlphaLISA®-compatible optical cube.

[0455] The raw signals obtained from the AlphaLISA® assay are analyzed using Geneda Screener® 17.0.3. Within this program, the data are normalized to 32 wells treated with an inhibitory control (maximum inhibition / positive control) and 32 wells treated with 0.375% DMSO alone (minimum inhibition / negative control) to calculate the compound's activity %.
