Nitrogen-containing Macrocyclic Compounds, Pharmaceutical Composition and Use ThereofField of Invention
[0001] The present invention relates to nitrogen-containing macrocyclic compounds, pharmaceutical composition and use thereof.
[0002] Prior Arts
[0003] RAS proteins belong to a protein superfamily of small GTPase that has an essential role in signal transduction and cellular proliferation. Alterations in RAS proteins, which include KRAS, HRAS and NRAS, commonly occur during oncogenesis (~ 30%of tumors) . Approximately 85%of RAS-driven cancers are caused by mutations in the KRAS isoform, which are associated with some of the deadliest cancers, including non-small-cell lung cancer (NSCLC) , pancreatic ductal adenocarcinoma (PDAC) , and colorectal cancer (CRC) (Nat Rev Drug Discov. 2014; 13 (11) : 828-851. ) . The majority of oncogenic RAS mutations occurs in hotspots at codons 12, 13, and 61, resulting in the impairment of GTP hydrolysis activity and the more RAS is in GTP-bound (ON) status. As a result, oncogenic signaling pathways are constantly activated leading to cell proliferation and survival (Nat. Commun. 2021, 12 (1) : 1808) . Among KRAS-driven tumors, over 80%of all oncogenic mutations occur at codon 12, with the most common mutations being KRASG12C, KRASG12D and KRASG12V (Cancer Res. 2012; 72 (10) : 2457-2467) .
[0004] RAS proteins can response to different stimuli and activate multiple signaling pathways, including RAS-RAF-MEK-ERK mitogen-activated kinase signaling (MAPK) pathway, PI3K / AKT pathway, and other signaling pathways (Signal Transduct Target Ther. 2021; 6 (1) : 386) . Normally, RAS proteins cycle between an inactive, GDP-bound (OFF) state and an active, GTP-bound (ON) state to regulate cell growth, proliferation, differentiation, and survival; essentially controlling key aspects of the cell cycle and signaling pathways. (Science. 1990; 247 (4945) : 939-945) . However, mutations in RAS genes lead to a markedly increased ratio of RAS-GTP to RAS-GDP and lock RAS proteins ina constitutive activate state (Cancer Discov. 2022; 12 (4) : 899-912) .
[0005] KRAS has been considered an ‘undruggable’ therapeutic target owing to a lack of pharmacologically targetable pockets. A major breakthrough in KRAS targeting is the discovery of inhibitors binding covalently and selectively to OFF-state KRASG12C. Despite the initial success of KRAS G12C inhibitors like sotorasib and adagrasib in the treatment of NSCLC, acquired resistance as well as adaptive resistance eventually occur in most patients, with a median progression-free survival (PFS) of ~6 months (Ther Adv Med Oncol. 2023; 15: 17588359231160141; N Engl J Med. 2021; 384 (25) : 2382-2393; Nature. 2020; 577 (7790) : 421-425; Nat Commun. 2024; 15 (1) : 7554) . In addition, KRAS G12C inhibitors only cover a small fraction of RAS mutations, over 85%of all RAS-mutated or wild-type amplified cancers still lack effective therapies (Nat Rev Clin Oncol. 2022; 19 (10) : 637-655) . There remains a high unmet medical need in RAS-mutated cancers.
