HETEROCYCLE ULK1 / 2 INHIBITORS AND METHODS OF USE THEREOF
[0001] CROSS-REFERENCE
[0002] This application claims the benefit of PCT Application No. PCT / CN2024 / 082265, filed March 18, 2024, which application is incorporated herein by reference in its entirety.BACKGROUND
[0003] Autophagy, an evolutionarily conserved process, serves as a fundamental mechanism for maintaining cellular homeostasis by degrading and recycling cellular components. These cellular constituents are sequestrated by double-membraned vesicles called autophagosomes. Autophagosomes then fuse with lysosomes, where their contents are broken down into essential building blocks, such as amino acids, fatty acids, and nucleotides, which can be used to support cellular functions and energy production. Dysregulation of autophagy is associated with a range of diseases, including cancer, neurodegenerative disorders, and autoimmune diseases. The role of autophagy in cancer is complex and context-dependent. On the one hand, autophagy can promote tumor cell survival by recycling damaged organelles and providing nutrients, aiding tumor cell adaptation to stressful conditions, including hypoxia, nutrient deprivation, and chemotherapy. On the other hand, excessive autophagy can lead to self-destruction of tumor cells.
[0004] RAS genes, including KRAS, NRAS and HRAS, play an important role in regulating cell growth, differentiation, and survival. Mutations in these genes, collectively referred to as RAS mutations, are among the most frequently observed genetic alterations in human cancers. They are particularly prevalent in pancreatic cancer (over 90%of cases) , colorectal cancer (30-50%of cases) , and lung cancer (about 30%cases) , among others. Tumor cells with RAS mutations are highly proliferative and less susceptible to chemotherapy and targeted therapies. They can activate the autophagy pathway for survival and diminish the efficacy of chemotherapeutic agents and targeted therapies; hence the combination of autophagy inhibitors with chemotherapeutic agents or RAS pathway targeted therapies may provide synergistic or additive effects for RAS-mutant cancers.SUMMARY

[0024] INCORPORATION BY REFERENCE
[0025] All publications, patents, and patent applications mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication, patent, or patent application was specifically and individually indicated to be incorporated by reference. To the extent publications and patents or patent applications incorporated by reference contradict the disclosure contained in the specification, the specification is intended to supersede and / or take precedence over any such contradictory material.DETAILED DESCRIPTION
[0026] Currently, the most widely used autophagy inhibitors are anti-malarial agents, chloroquine (CQ) and hydroxychloroquine (HCQ) . These anti-malarial agents mainly inhibit autophagy by impairing the fusion of autophagosomes and lysosomes. However, they may exhibit retinal toxicity because of poor selectivity. The development of selective autophagy inhibitors represents a significant innovation in the field of medicine.
[0027] ULK1 (unc-51-like kinase 1) is a serine / threonine kinase and a central component of the ULK1 complex, which includes ULK1 itself, ATG13 (autophagy-related protein 13) , FIP200 (focal adhesion kinase family interacting protein of 200 kDa) , and ATG101. This complex acts as the primary initiator of autophagy, orchestrating the formation of autophagosomes. ULK1’s activity is tightly regulated by various cellular signals. Notably, it is negatively regulated by the mammalian target of rapamycin complex 1 (mTORC1) . In response to nutrient deprivation or cellular stress, mTORC1 inhibition leads to the activation of ULK1. Activated ULK1 phosphorylates downstream targets, triggering autophagosome formation and the subsequent process. In most cell lines, loss of ULK1 is sufficient to disrupt autophagy; however, ULK2 is thought to act with a degree of redundancy in this pathway. This redundancy is highlighted by the need to knock out both ULK1 and ULK2 in mice to show the same neonatal lethality seen with loss of other core autophagy genes such as ATG5 and ATG7. Moreover, kinase-dead mutants of ULK result in a block of canonical autophagy initiation, suggesting that small molecule inhibitors of ULK kinase activity would be able to block autophagy.
[0028] In conclusion, the application of autophagy inhibitors, such as ULK kinase inhibitors, in combination with chemotherapeutic agents or RAS pathway targeted therapies in cancer treatment is a promising strategy that addresses the challenges associated with RAS-driven cancers and autophagy-induced resistance. While further research and clinical trials are needed to optimize this approach, it may improve the outcomes of cancer patients with RAS pathway mutations.

[0230] Chemical Synthesis
[0231] The examples and preparations provided below illustrated and exemplify the compounds described herein and methods of preparing such compounds. In general, the compounds described herein may be prepared by processes known in the general chemical arts.
[0232] The compounds of the present invention can be prepared using various synthetic routes, including those described below, starting from commercially available materials. Starting materials of the invention, are either known, commercially available, or can be synthesized in analogy to or according to methods that are known in the art. Many starting materials may be prepared according to known processes and, in particular, can be prepared using processes described in the examples. In synthesizing starting materials, functional groups in some cases are protected with suitable protecting groups when necessary. Functional groups may be removed according to known procedures in the art.
[0233] The protection of functional groups by protecting groups, the protecting groups themselves, and their removal reactions (commonly referred to as “deprotection” ) are described, for example, in standard reference works, such as J. F. W. McOmie, Protective Groups in Organic Chemistry, Plenum Press, London and New York (1973) , in T. W. Greene, Protective Groups in Organic Synthesis, Wiley, New York (1981) , in The Peptides, Volume 3, E. Gross and J. Meienhofer editors, Academic Press, London and New York (1981) .
[0234] All synthetic procedures described herein can be carried out under known reaction conditions, advantageously under those described herein, either in the absence or in the presence (usually) of solvents or diluents.
[0235] The invention further encompasses “intermediate” compounds, including structures produced from the synthetic procedures described, whether isolated or not, prior to obtaining the finally desired compound. Structures resulting from carrying out steps from a transient starting material, structures resulting from divergence from the described method (s) at any stage, and structures forming starting materials under the reaction conditions are all “intermediates” included in the invention. Further, structures produced by using starting materials in the form of a reactive derivative or salt, or produced by a compound obtainable by means of the process according to the invention and structures resulting from processing the compounds of the invention in situ are also within the scope of the invention.
[0236] New starting materials and / or intermediates, as well as processes for the preparation thereof, are likewise the subject of this invention. In select embodiments, such starting materials are used and reaction conditions so selected as to obtain the desired compound (s) .
[0237] Starting materials of the invention, are either known, commercially available, or can be synthesized in analogy to or according to methods that are known in the art. Many starting materials may be prepared according to known processes and, in particular, can be prepared using processes described in the examples. In synthesizing starting materials, functional groups in some cases are protected with suitable protecting groups when necessary. Protecting groups, their introduction and removal are described above.
[0238] All reagents and solvents were obtained commercially unless stated otherwise. All commercial reagents and solvent were used without purification unless stated otherwise. When required, some reagents and solvents were purified by standard techniques. For example, tetrahydrofuran may be purified by distillation from sodium.
[0239] Reaction progress was monitored by reverse-phase HPLC and / or thin-layer chromatography (TLC) . Liquid chromatography-mass spectrometry was performed using either Waters or Shimadzu 2010EV LCMS instruments using water and acetonitrile or methanol doped with 0.1%formic acid. TLC was performed using silica gel 60 F254 pre-coated plates (0.25 mm) . Flash chromatography was performed using silica gel (32-63 μm particle size) or aluminum oxide (activated, basic, about150 mesh size) . Automated chromatographic purification was carried out using pre-packed silica or C18 cartridges (from RediSep and Luknova) and eluted using an ISCO Companion system. Reverse phase purifications were conducted using water and acetonitrile or methanol doped with 0.1%formic acid. All final product compounds were purified using one of these two chromatographic methods. Purity and characterization of compounds was established by a combination of TLC, liquid chromatography-mass spectroscopy (LC-MS) and Nuclear Magnetic Resonance (NMR) analytical techniques. 1H and 13C NMR spectra were obtained on a Joel 400 spectrometer at 400 MHz and 101 MHz, respectively. Chemical shifts are reported in δ(ppm) and were internally referenced to deuterated solvent signals.
[0240] The size and scale of the synthetic methods may vary depending on the desired amount of end product. It is understood that while specific reactants and amounts are provided in the Examples, one of skill in the art knows other alternative and equally feasible sets of reactants that may also yield the same compounds. Thus, where general oxidizers, reducers, solvents of various nature (aprotic, nonpolar, polar, etc. ) are utilized, equivalents may be known in the art and are herein contemplated for use in the present methods.
[0241] Many of the steps below indicate various workups following termination of the reaction. A work-up involves generally quenching of a reaction to terminate any remaining catalytic activity and starting reagents. This is generally followed by addition of an organic solvent and separation of the aqueous layer from the organic layer. The product is typically obtained from the organic layer and unused reactants and other spurious side products and unwanted chemicals are generally trapped in the aqueous layer and discarded. The work-up in standard organic synthetic procedures found throughout the literature is generally followed by drying the product by exposure to a drying agent, such as anhydrous Na2SO4, to remove any excess water or aqueous byproducts remaining partially dissolved in the organic layer and concentration of the remaining organic layer. Concentration of product dissolved in solvent may be achieved by any known means, such as evaporation under pressure, evaporation under increased temperature and pressure, and the like. Such concentration may be achieved by use of standard laboratory equipment such as rotary-evaporator distillation, and the like. This is optionally followed by one or more purification steps which may include, but is not limited to, flash column chromatography, filtration through various media and / or other preparative methods known in the art and / or crystallization / recrystallization. (See, for instance, Addison Ault, “Techniques and Experiments for Organic Chemistry, ” 6th Ed., University Science Books, Sausalito, Calif., 1998, Ann B. McGuire, Ed., pp. 45-59) .
