Description

KRAS INHIBITORS Background

[0001] The MAPK / ERK signaling pathway relays extracellular stimuli to the nucleus, thereby regulating diverse cellular responses including cell proliferation, differentiation, and apoptosis. KRAS protein is an initiator of the MAPK / ERK signaling pathway and functions as a switch responsible for inducing cell division. In its inactive state, KRAS binds guanosine diphosphate (GDP), effectively sending a negative signal to suppress cell division. In response to an extracellular signal, KRAS is allosterically activated allowing for nucleotide exchange of GDP for 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 cell signaling receptors. Examples of the proteins recruited by KRAS-GTP are c-Raf and PI3-kinase. KRAS, as a GTP-ase, converts the bound GTP back to GDP, thereby returning itself to an inactive state, and again propagating signals to suppress cell division. KRAS gain of function mutations exhibit an increased degree of GTP binding and a decreased ability to convert GTP into GDP. The result is an increased MAPK / ERK signal which promotes cancerous cell growth. Missense mutations of KRAS at codon 12 are the most common mutations and markedly diminish 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, it has been a difficult therapeutic target. (Cox, A.D. Drugging 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] Thus far, work has focused on KRAS G12C mutant inhibitors (e.g., WO2019 / 099524, WO2020 / 081282, WO2020 / 101736, WO2020 / 146613, and WO2021 / 118877 disclose KRAS G12C inhibitors), whereas WO2021 / 041671 discloses small molecules inhibitors of KRAS G12D and WO2017 / 011920 discloses small molecule inhibitors of KRAS G12C, G12D, and G12V.

[0004] There remains a need to provide alternative, small molecule KRAS inhibitors. In particular, there is a need to provide orally deliverable KRAS inhibitors that are useful for treating cancer. More particularly, 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 greater efficacy at the same or reduced KRAS inhibitory activity. Further, there is a desire to provide KRAS inhibitors that exhibit better pharmacokinetic / pharmacodynamic properties. Even further, there is a desire to provide KRAS inhibitors that exhibit good oral bioavailability and target coverage (KRAS G12V inhibition). Additionally, there is a need to provide KRAS inhibitors that exhibit selective inhibition preference for KRAS G12V mutant over KRAS wild-type and preferably also exhibit selective inhibition preference for KRAS G12V mutant over HRAS or NRAS. Also, there is a need to provide more potent KRAS inhibitors that exhibit increased efficacy with reduced or minimized untoward or undesired effects. The present invention addresses one or more of these needs by providing novel KRAS inhibitors. Summary

[0201] Individual isomers, enantiomers, diastereomers, and atropisomers may be separated or resolved at any convenient point in the synthesis of compounds listed below, by methods such as selective crystallization techniques or chiral chromatography (See for example, J. Jacques, et al., "Enantiomers, Racemates, and Resolutions", John Wiley and Sons, Inc., 1981, and E.L. Eliel and S.H. Wilen,” Stereochemistry of Organic Compounds”, Wiley- Interscience, 1994). The molecules described herein include compounds that are atropisomers and which can exist in different conformations or as different rotomers. Atropisomers are compounds that exist in different conformations arising from restricted rotation about a single bond. Atropisomers can be isolated as separate chemical species if the energy barrier to rotation about the single bond is sufficiently high that the rate of interconversion is slow enough to allow the individual rotomers to be separated from each other. This description is intended to include all of the isomers, enantiomers, diastereomers, and atropisomers possible for the compounds disclosed herein or that could be made using the compounds disclosed herein. In the molecules described herein, only molecules in which the absolute conformation of a chiral center (or atropisomer conformation) is known have used naming conventions or chemical formula that are drawn to indicate the chirality or atropisomerism. Those of skill in the art will readily understand when other chiral centers are present in the molecules described herein and be able to identify the same.

[0202] Compounds of any one of Formula I that are chemically capable of forming salts are readily converted to and may be isolated as a pharmaceutically acceptable salt. Salt formation can occur upon the addition of a pharmaceutically acceptable acid to form the acid addition salt. Salts can also form simultaneously upon deprotection of a nitrogen or oxygen, i.e., removing the protecting group. Examples, reactions and conditions for salt formation can be found in Gould, P.L., “Salt selection for basic drugs,” International Journal of Pharmaceutics, 33: 201-217 (1986); Bastin, R.J., et al. “Salt Selection and Optimization Procedures for Pharmaceutical New Chemical Entities,” Organic Process Research andDevelopment, 4: 427-435 (2000); and Berge, S.M., et al., “Pharmaceutical Salts,” Journal of Pharmaceutical Sciences, 66: 1-19, (1977).

[0267] The following assays demonstrate that the exemplified compounds are potent inhibitors of KRAS G12V and inhibit growth of certain tumors in vitro and / or in vivo. Cellular Phospho-ERK AlphaLISA®Assay for KRAS Inhibition

[0268] The purpose of these assays is to quantify the ability of test compounds to selectively inhibit KRAS signaling in cells with amplified KRAS and expressing activating KRAS G12 mutations (Table 1A). Cancer cell lines used in this study were selected based on the presence of homozygous activating KRAS G12 mutations, or amplification of the KRAS gene. Table 1A: Cell Line Information Cell Line Name RAS Mutation / Features Assay Seeding Density (Cells / Well) MKN45 WT KRAS Amplification / Human Gastric Cancer 20,000 SW620 KRAS G12V / Human Colorectal Cancer 20,000

[0269] The compounds’ activity is determined by measuring changes in the phosphorylation levels of the downstream effector Extracellular Signal-regulated Kinase-1 and 2 (ERK1 / 2) in the compound treated cells. Phosphorylation levels of ERK-1 / 2 are measured using theAlphaLISA®SureFire®Ultra™ p-ERK 1 / 2 (Thr202 / Tyr204) Assay Kit (#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 cellular lysates using bead-based Alpha technology. The assay kit contains two antibodies, one that binds the phospho-Thr202 / Tyr204 epitope on ERK-1 / 2, and another one that recognizes a separate site on the protein. One of these antibodies is biotinylated and associated with streptavidin-coated Alpha Donor beads, the other antibody is conjugated to AlphaLISA®Acceptor beads. When ERK-1 / 2 is phosphorylated in cellular lysate, the Donor and Acceptor beads are brought into proximity with each other. When the Donor bead is excited by 600 nm wavelength light, a photosensitizer inside the bead converts ambient oxygen to an excited singlet state. When the Acceptor bead is within 200 nm of this reaction, the singlet oxygen reacts with the Acceptor leading to a chemiluminescent emission. The amount of light measured is proportional to the amount of phosphorylated ERK-1 / 2 in the lysate. The AlphaLISA®SureFire®Ultra™p-ERK 1 / 2 (Thr202 / Tyr204) Assay Kit contains AlphaLISA®antibody-conjugated Donor and Acceptor Beads, Lysis buffer concentrate, and a set of proprietary buffers (Activation Buffer, Reaction Buffer 1, Reaction Buffer 2, and Dilution Buffer).

[0270] To perform the assays, test compounds and controls are acoustically dispensed (Labcyte ECHO®, San Jose, CA) into a white 384-well assay plate (Proxiplate-384, PerkinElmer #6008280) in a 10-point 3-fold dilution series in 30 nL DMSO. Cells are then added to the assay plate in 8 µL per well assay medium (HBSS, Sigma #55021C, 10% FBS, GIBCO # 10082-147) at a cell line specific density (Table 1A). The final compound concentrations range from 0.5 to 10,000 nM and the final DMSO concentration is 0.375% in each well. Maximum signal control wells contain 0.375% DMSO only (negative control), and minimum signal control wells contain 10,000 nM control compound (positive control). Cells in suspension are incubated with the test and reference compounds for 2 h at 37°C / 5 % CO2. Following the 2 h incubation, cells are lysed by adding 2 µL of the AlphaLISA®Lysis buffer concentrate (5X) supplemented with protease / phosphatase inhibitor cocktail (Thermo Scientific # 78442). The assay plate is covered with an opaque lid and shaken at 750 rpm on a multi-plate shaker (Heidolph, Schwabach, Germany) for 30 min at room temperature toinduce cell lysis. During the lysis, the AlphaLISA®Acceptor beads are diluted 1:50 in a prepared buffer mixture (1:1 AlphaLISA®Reaction Buffers 1 and 2 with a 1:25 dilution of AlphaLISA®Activation Buffer). Following cell lysis, plates are centrifuged briefly, and 5 µL per well prepared Acceptor beads are added. The plate is then covered and incubated in the dark for 2 h at room temperature. During the Acceptor bead incubation, Donor beads are prepared by diluting the Alpha streptavidin Donor beads 1:50 in AlphaLISA®Dilution buffer. Following the Acceptor bead incubation, 5 µL per well of Donor bead mixture is added to the plates. Plates are then covered and allowed to incubate in the dark at room temperature for 2 h. 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 optics cube.

[0271] Raw signal obtained from the AlphaLISA®assay is analyzed using Genedata Screener®17.0.3. Within the program, data is normalized to 32 wells treated with inhibition control (max inhibition / positive control) and 32 wells treated with 0.375% DMSO only (minimum inhibition / negative control) to calculate the % Activity of the compound:% Activity values are fit to a four-parameter non-linear logistic equation using Genedata Screener®17.0.3. to -determine IC50 values:Where y = % Activity, Bottom = minimum asymptote, Top = maximum asymptote, x = compound concentration, IC50= the compound concentration where half maximal activity is achieved, and h = the Hill Coefficient.
