[0001] CROSS-REFERENCE TO PRIOR APPLICATIONS This application claims the benefit of U.S. Provisional Patent Application No. 63 / 383,674, filed November 14, 2022, U.S. Provisional Patent Application No. 63 / 497,978, filed April 24, 2023, and U.S. Provisional Patent Application No. 63 / 582,751, filed September 14, 2023, each of which is incorporated by reference in its entirety.

[0002] The present disclosure provides compounds that have activity as inhibitors of mutant KRAS proteins. The present disclosure also provides pharmaceutical compositions, uses, and methods comprising the compounds for treating specific disorders such as cancer, including, but not limited to, non-small cell lung cancer, colorectal cancer, pancreatic cancer, appendix cancer, endometrial cancer, esophageal cancer, cancer of unknown primary site, ampullary cancer, gastric cancer, small intestine cancer, sinus cancer, bile duct cancer, or melanoma. [Background technology]

[0003] Since its identification in 1982 as one of the first human oncogenes (Der et al., 1982), KRAS (Kirsten rat sarcoma viral oncogene homolog) has been the subject of extensive academic and industrial research as a key node in the MAPK signaling pathway, a transforming factor in a network of parallel effector pathways (e.g., PI3K / AKT) (Vojtek et al., 1998), and a potential target for anticancer drugs (Malumbres et al., 2003). Despite advances in the development of inhibitors of upstream and downstream nodes of the MAPK pathway (e.g., EGFR (Sridhar et al., 2003), BRAF (Holderfield et al., 2014), and MEK (Caunt et al., 2015), the KRAS protein has historically proven resistant to direct inhibition.

[0004] KRAS is a G protein that couples extracellular mitogenic signaling to intracellular growth-promoting responses. KRAS acts as an intracellular "on / off" switch. Mitogen stimulation induces the binding of GTP to KRAS, resulting in a conformational change that allows KRAS to interact with downstream effector proteins, leading to cell proliferation. Normally, growth-promoting signaling is regulated by the action of GTPase-activating proteins (GAPs), which revert KRAS to its GDP-bound, non-proliferative state. KRAS mutations impair the regulated cycling of KRAS between these GDP- and GTP-bound states, resulting in the accumulation of the active GTP-bound state and impaired cell proliferation (Simanshu et al., 2017).

[0005] Attempts to develop inhibitors of mutant KRAS proteins have historically been hampered by the absence of a druggable pocket on the protein surface (Cox et al., 2014). In 2013, Shokat et al. identified a covalent inhibitor of a common (O'Bryan, 2019) oncogenic mutant of KRAS, KRAS G12C, that bound to a previously unrecognized allosteric pocket on GDP-KRAS G12C and prevented subsequent activation (Ostream et al., 2013). This discovery led to significant new efforts in KRAS inhibitor research and recently led to the entry of KRAS inhibitors into human clinical trials. [Prior art documents] [Non-patent literature]

[0007] While some progress has been made with KRAS G12C inhibitors, there is continued interest and effort to develop inhibitors of KRAS, particularly inhibitors of other KRAS such as KRAS G12D, G12V, G12A, G12S, G13D, Q61H, Q61L or G12C. Thus, there is a need to develop new inhibitors of KRAS G12D, G12V, G12A, G12S, G13D, Q61H, Q61L or G12C for the treatment of disorders such as cancer. [Means for solving the problem]

[0305] definition The following definitions are provided to facilitate understanding of the scope of the present disclosure.

[0306] Unless otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term "about." Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending on the standard deviation found in their respective testing measurements.

[0307] As used herein, when any variable occurs more than once in a chemical formula, its definition on each occurrence is independent of its definition at every other occurrence. In the case of conflicts between the chemical structure and the chemical name, the chemical structure is determinative of the compound's identity.

[0308] stereoisomer The compounds of the present disclosure may contain, for example, double bonds, one or more asymmetric carbon atoms, and bonds with rotational hindrance, and thus may exist as stereoisomers, such as double bond isomers (i.e., geometric isomers (E / Z)), enantiomers, diastereomers, and atropisomers. Accordingly, it should be understood that the scope of the present disclosure encompasses all possible stereoisomers of the exemplified compounds, including stereoisomerically pure forms (e.g., geometrically pure, enantiomerically pure, diastereomerically pure, and atropisomerically pure), as well as mixtures of stereoisomers (e.g., mixtures of geometric isomers, enantiomers, diastereomers, and atropisomers, or mixtures of any of the foregoing) of any chemical structure (in whole or in part) disclosed herein, unless the stereochemistry is specifically specified.

[0309]

[0013] If the stereochemistry of a structure, or portion of a structure, is not shown, for example, with bold or dashed lines, then the structure, or portion of the structure, is to be interpreted as encompassing all stereoisomers thereof. If the stereochemistry of a structure, or portion of a structure, is shown, for example, with bold or dashed lines, then the structure, or portion of the structure, is to be interpreted as encompassing only the stereoisomer shown. A bond drawn with a wavy line indicates that both stereoisomers are encompassed. This wavy line should not be confused with a wavy line drawn perpendicular to a bond, which indicates where a group is attached to the rest of the molecule.

[0310] The term "stereoisomer" or "stereoisomerically pure" compound, as used herein, refers to one stereoisomer (e.g., geometric isomer, enantiomer, diastereomer, and atropisomer) of a compound that is substantially free of other stereoisomers of that compound. For example, a stereoisomerically pure compound having one chiral center will be substantially free of the mirror-image enantiomer of that compound, and a stereoisomerically pure compound having two chiral centers will be substantially free of other enantiomers or diastereomers of that compound. A typical stereoisomerically pure compound contains greater than about 80% by weight of one stereoisomer of the compound and less than about 20% by weight of other stereoisomers of the compound, or greater than about 90% by weight of one stereoisomer of the compound and less than about 10% by weight of other stereoisomers of the compound, or greater than about 95% by weight of one stereoisomer of the compound and less than about 5% by weight of other stereoisomers of the compound, or greater than about 97% by weight of one stereoisomer of the compound and less than about 3% by weight of other stereoisomers of the compound.

[0311] The present disclosure also encompasses pharmaceutical compositions comprising stereoisomerically pure forms and the use of stereoisomerically pure forms of any of the compounds disclosed herein. Furthermore, the present disclosure also encompasses pharmaceutical compositions comprising mixtures of stereoisomers of any of the compounds disclosed herein and the use of said pharmaceutical compositions or mixtures of stereoisomers. These stereoisomers or mixtures thereof can be synthesized according to methods well known in the art and disclosed herein. Mixtures of stereoisomers can be resolved using standard techniques, such as chiral columns or chiral resolving agents. Furthermore, the present disclosure encompasses pharmaceutical compositions comprising mixtures of any of the compounds disclosed herein and one or more other active agents disclosed herein. See, for example, Jacques et al., Enantiomers, Racemates and Resolutions (Wiley-Interscience, New York, 1981); Wilen et al., Tetrahedron 33:2725; Eliel, Stereochemistry of Carbon Compounds (McGraw-Hill, NY, 1962); and Wilen, Tables of Resolving Agents and Optical Resolutions, page 268 (Eliel, Ed., University of Notre Dame Press, Notre Dame, IN, 1972).

[0312] tautomers As known to those skilled in the art, certain compounds disclosed herein can exist in one or more tautomeric forms.Because one chemical structure can only be used to represent one tautomeric form, for convenience, reference to a compound of a given structural formula should be understood to include other tautomeric forms of said structural formula.Therefore, the scope of the present disclosure should be understood to encompass all tautomeric forms of the compounds disclosed herein.

[0360] General analytical and purification methods Provided in this section are descriptions of the general analytical and purification methods used to prepare the specific examples provided herein.

[0361] Chromatography: Unless otherwise indicated, crude product-containing residues were purified by passing the crude material or concentrate through either a Biotage or ISCO brand silica gel column pre-packed with flash silica (SiO) and eluting the product from the column with a solvent gradient as specified.

[0362] Preparative HPLC Method: Where indicated, compounds described herein were purified by reverse-phase HPLC using a Waters FractionLynx or Gilson semi-preparative HPLC-MS system using one of two HPLC columns: (a) a Phenomenex Gemini column (5 micron, C18, 150x30mm) or (b) a Waters X-select CSH column (5 micron, C18, 100x30mm). A typical run through the instrument involved eluting with a linear gradient of 10% (v / v) to 100% MeCN (0.1% v / v formic acid) in water (0.1% formic acid) over 10 minutes at 45 mL / min; conditions may be varied to achieve optimal separation.

[0363] Proton NMR spectra: Unless otherwise indicated, all 1 H NMR spectra were collected on a Bruker NMR instrument at 300, 400, or 500 MHz. All observed protons are reported as parts per million (ppm) downfield from tetramethylsilane (TMS) using the internal solvent peak as the reference. Some protons may be due to exchange with D from MeOD or due to signal suppression. 1 The H signal may be absent.

[0364] Mass Spectrum (MS): Unless otherwise indicated, all mass spectral data for starting materials, intermediates, and / or exemplary compounds are reported as mass / charge (m / z) with the [M+H]+ molecular ion. The reported molecular ions were obtained by electrospray detection (commonly referred to as ESI MS) using a Waters Acquity UPLC / MS system. As will be appreciated by those skilled in the art, compounds with isotopic atoms such as bromine are generally reported according to the detected isotopic pattern.
