CONDENSED MACROCYCLIC COMPOUNDS AS RAS INHIBITORS FOR THE TREATMENT OF CANCER CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims priority from Application Nos. PCT / CN2024 / 124791, filed October 14, 2024, and PCT / CN2025 / 095776, filed May 19, 2025. The contents of these priority applications are incorporated by reference herein in their entirety. TECHNICAL FIELD
[0002] The present invention belongs to the field of medicine, and specifically relates to condensed macrocyclic compounds and their stereoisomers, as well as related pharmaceutically acceptable salts, solvates, eutectic forms, or deuterated compounds, and to their use in the treat- ment of RAS protein-mediated diseases. BACKGROUND
[0003] The RAS family (including KRAS4A, KRAS4B, HRAS, and NRAS) is a family of small, membrane-bound guanine nucleotide-binding proteins that act as molecular switches by cycling between an active GTP-bound state and an inactive GDP-bound state. When RAS binds to a GEF family protein such as SOS1, its conformation changes, and its affinity for GDP is reduced. This causes RAS to dissociate from GDP and binding to GTP, thus becoming active. In normal cells, activation of receptor tyrosine kinases such as epidermal growth factor receptor (EGFR) promotes the exchange of GDP and GTP in (and therefore activation of) RAS, which plays a key role in regulating cell survival, proliferation, and differentiation through multiple cascading reactions, including the PI3K-AKT-mTOR, RAF-MEK-ERK, and RALGDS-RAL pathways. Mutations in RAS are often driving forces for carcinogenesis and tumor development, as they disrupt the guanine exchange cycle and lock RAS in the activated state, continuously activating downstream signaling pathways and leading to the development of tumors.
[0004] RAS mutations occur in approximately 19% of all cancers and play an important role in tumor occurrence and progression. Among them, KRAS is the most commonly mutated subtype, followed by NRAS and HRAS. KRAS mutations commonly occur in pancreatic duc- tal adenocarcinoma, lung adenocarcinoma, and colorectal adenocarcinoma, while NRAS muta- tions have a relatively higher frequency in hematologic malignancies such as chronic myeloidleukemia and acute myeloid leukemia, as well as in malignant melanoma, thyroid cancer, and laryngeal cancer. HRAS mutations have a relatively higher mutation rate in head and neck squamous cell carcinoma, bladder cancer, salivary gland carcinoma, and oral cancer.
[0005] Given the key role of the RAS family of proteins in cancer occurrence and progres- sion, there remains a need for the development of RAS inhibitors. SUMMARY OF THE INVENTION
[0006] Provided herein are Ras inhibitors that function as molecular glues. The approach described herein entails formation of a high affinity three-component complex between a syn- thetic ligand, and two intracellular proteins that do not interact under normal physiological con- ditions – the target of interest (e.g., Ras) and a widely expressed cytosolic chaperone in cells (e.g., cyclophilin A). In some embodiments, the Ras molecular glues described herein induce a new binding pocket in Ras by forming a high-affinity three-component complex between the Ras protein and the cytosolic chaperone, cyclophilin A. Without being bound by theory, the in- ventors believe that one way the inhibitory effect on Ras is effected by compounds of the in- vention and the three-component complexes they form, is by steric occlusion of the interaction site between Ras and downstream effector molecules, such as RAF and PI3K, which are re- quired for propagating the oncogenic signal.

In some embodiments, the linker results in a compound capable of achieving an IC50of 1µM or less in the Ras-RAF disruption assay.
[0274] Without being bound by theory, the inventors postulate that non-covalent interac- tions of “Q” and the chaperone protein (e.g., cyclophilin A) may contribute to the inhibition of Ras activity. For example, van der Waals, hydrophobic, hydrophilic and hydrogen bond inter- actions, and combinations thereof, may contribute to the ability of the compounds of the pre- sent invention to form complexes andact as Ras inhibitors. The inventors also postulate that “Q” also imparts structural rigidity to the compounds, which may optimize these non-covalent interactions, thereby contributing to the inhibition of Ras activity.
[0275] In some embodiments, the linker comprises 20 or fewer linear atoms, optionally 15 or fewer linear atoms or 10 or fewer linear atoms. In some embodiments, the linker has a mo- lecular weight of under 500 g / mol, optionally under 400 g / mol, under 300 g / mol, under 200 g / mol, under 100 g / mol, or under 50 g / mol.

[0280] General synthetic procedure for preparing compounds of formula (IIIa) and formula (IIIb) is shown in Scheme 1 below: Scheme 1
[0281] Scheme 1 illustrates the preparation of a compound of formula (IIIa) or formula (IIIb). The synthetic sequence commenced with the Suzuki coupling of a compound of for- mula (1) with a compound of formula (2) using Pd(dppf)Cl₂ and K₂CO₃ to provide a compound of formula (3). Subsequently, the compound of formula (3) was converted to a compound of formula (4) under standard Yamanaka-Sonogashira indole synthesis conditions [Pd(PPh₃)₂Cl₂, CuI]. This was followed by a Friedel-Crafts acylation of the compound of formula (4), employ- ing BCl₃-AlCl₃ as a Lewis acid, to furnish a compound of formula (5). Deprotonation of (5) with an organolithium base such as LDA yielded a compound of formula (6), which was then reduced via a triethylsilane-mediated conversion of the carbonyl group to a methylene group, affording a compound of formula (7). Reduction of (7) with a reducing agent (e.g., LiBH₄) gave a compound of formula (8). A subsequent Suzuki coupling of (8) [Pd(PPh₃)₂Cl₂, KOAc] provided a compound of formula (9), which was then coupled with a compound of for- mula (10) under similar Suzuki conditions [Pd(dppf)Cl₂, KOAc] to give a compound of for- mula (11). Deprotection of the ester in (11), for example via hydrolysis with Me₃SnOH, yielded a compound of formula (12). Condensation of (12) using a coupling reagent such as HATU provided a compound of formula (13), which underwent acid-mediated deprotection (e.g., with TFA) to give a compound of formula (14). Finally, a routine coupling between thecompound of formula (14) and acid (15), using a coupling reagent (e.g., HATU) and an organic base (e.g., DIPEA), provided a compound of formula (16). Deprotection and cyclization of (16) then furnished the final compound of formula (17). Example 2.

[0466] The following compound was used as the reference compound.Cell viability assay
[0467] Selective screening using RAS-driven and RAS-non-driven cells: (1) RAS-driven cells, including cells with persistent RAS activation due to RAS mutations and upstream EGFR activation. Cells that are continuously activated due to RAS mutations, such as KRAS G12D (AsPC-1, HPAC, AGS, etc.) mutant cells, KRAS G12C (NCI-H358, MIAPaCa-2, etc.) KRAS G13D (LOVO, HCT15, etc.) mutant cells, etc. Cells with continuous activation of RAS due to EGFR mutations, such as EGFREx19del (PC-9, etc.) mutant cells, EGFRT790M / L858R (NCI- H1975, etc.) mutant cells, etc.; (2) Non-RAS driven cells, including BRAFV600E (A375, SK,) -MEL-3, etc.) mutant cells, RASWT (BxPC-3, etc.) cells, etc.
[0468] Specific experimental methods: The above cells were seeded in a 96-well plate at a density of 1000-10000 per well. Drugs were diluted in DMSO to make a 10 mM stock solu- tion. Subsequently, the drug was diluted in a 3-fold gradient to a final concentration of 1000 nM. The cells were treated with the drug for 5 days. Cell viability was then detected by the MTS method.
