Abstract
Description
Technical Field
[0002] This invention belongs to the field of biomedical technology, specifically relating to a macrocyclic compound with multi-target degradation activities of TRK, ROS1 and ALK, its preparation method and pharmaceutical applications. Background Technology
[0004] The cumulative genetic and epigenetic modifications of kinases (such as site mutations, deletions, insertions, amplifications, and translocations) lead to abnormal activation of cell signaling pathways, thereby driving cancer cell growth, proliferation, metastasis, and survival (Can. Lett. 2009, 281, 117-127; Nat. Rev. Gen. 2010, 11, 60-74). TRK, ROS1, and ALK fusion genes are closely related to the occurrence and development of various tumors.
[0005] Neurotrophic tyrosine receptor kinase (NTRK) genes encode tropomyosin receptor kinase (TRK), which can be activated through fusion events, thus becoming oncogenes. The NTRK family, including NTRK1, NTRK2, and NTRK3, is a pan-tumor oncogenic driver found in various cancer types. These mutations are relatively rare in common cancers such as breast, colorectal, and lung cancer, but are highly prevalent in some rare cancers, such as secretory-like breast cancer and infantile fibrosarcoma, with an incidence exceeding 90%. These oncogenes promote the synthesis of TRK fusion chimeric proteins, which are aberrantly expressed and persistently activated in a ligand-independent manner (Nat. Rev. Clin. Oncol. 2018, 15, 731-747). The FDA-approved TRK inhibitors larotrectinib, entrectinib, and ripretinib have demonstrated significant treatment response rates in NTRK fusion-positive cancers, independent of histological classification (J. Med. Chem. 2019, 62, 1731−1760; Eur. J. Med. Chem. 2023, 258, 115618; Cancer Discovery 2018, 8, 1227-1236). Despite the significant efficacy of these first-generation drugs, acquired resistance inevitably occurs, ultimately limiting the duration of drug response. The main mechanisms of acquired resistance to TRK inhibitors involve specific mutations in the kinase domains, such as SF mutations, GK mutations, and xDFG motif mutations. Among these, TRKA... G667C (xDFG mutation) and TRKA G595R (SF mutation) is the most common (J. Med. Chem. 2025, 68, 15233-15259).
[0006] ROS1 is a receptor tyrosine kinase encoded by the ROS1 proto-oncogene (N. Engl. J. Med. 2014, 371 1963-1971). Chromosomal rearrangements involving ROS1 and its fusion partner can produce persistently activated ROS1 fusion kinases, which act as oncogenic drivers in human cancers. In advanced non-small cell lung cancer (NSCLC), approximately 2% of patients have ROS1 fusions, with CD74-ROS1 and SLC34A2-ROS1 being the most common rearrangements (JTO Clin. Res. Rep. 2020, 1, 100048). The ROS1 kinase domain shares 70% sequence homology with anaplastic lymphoma kinase, and ROS1 gene rearrangements are generally mutually exclusive with ALK rearrangements. Due to their high homology, NSCLC with ROS1 rearrangements and ALK rearrangements are often treated with the same tyrosine kinase inhibitors. Crizotinib, an ALK / ROS1 / cMET inhibitor, achieved an objective response rate of 72% and a median progression-free survival of 19.2 months in treatment. It was the first tyrosine kinase inhibitor approved by the US Food and Drug Administration and the European Medicines Agency for the treatment of advanced ROS1 fusion-positive lung cancer (Ann. Oncol. 2019, 30 (7), 1121-1126). The second multi-kinase inhibitor, entrectinib, has intracranial activity against ROS1, ALK, and TRK. Based on a meta-analysis of efficacy data from the STARTRK-1, STARTRK-2, and ALKA-372-001 clinical trials, it has been approved for the treatment of metastatic ROS1-positive non-small cell lung cancer (Lancet Oncol. 2020, 21, 261-270). Although ROS1 inhibitors show significant initial efficacy, most patients eventually develop resistance, which has become a major challenge in clinical treatment, ultimately limiting the duration of their efficacy. Targeting mutations of the ROS1 kinase domain have been found in patient samples, the most common being the G2032R mutation (approximately 33%-41%). Other common mutations include D2033N (2.4%-6%), L2026M (1%), L1951R (1%), L2086F (3.6%), and S1986F / Y (2.4%-6%) (N. Engl. J. Med. 2013, 368, 2395−2401; Clin. Cancer Res. 2016, 22, 2351−2358; Clin. Cancer Res. 2021, 27(10), 2899−2909). In more than one-third of acquired resistance cases, some ROS1 mutations lead to resistance to crizotinib and lorlatinib, for which there are currently no effective treatment options.
[0007] Anaplastic lymphoma kinase (ALK) has been a promising therapeutic target in non-small cell lung cancer since its discovery in an anaplastic large cell lymphoma cell line in 1994 (Science 1994, 263, 1281-1284; Mol. Cancer 2018, 17, 52). Significant efforts have been invested in the research and development of small molecule ALK inhibitors (J. Med. Chem. 2013, 56, 5675-5690; J. Med. Chem. 2016, 59, 4948-4964). However, drug resistance issues limit the efficacy of kinase inhibitor-based therapies, particularly the compensatory upregulation of ALK observed when using ALK inhibitor antagonists (Pharmacol. Ther. 2017, 174, 138-144).
[0008] PROTAC, a protein degradation-targeting chimeric technology, can overcome acquired resistance by inducing the degradation of an entire protein through brief, low-dose drug exposure (J. Med. Chem. 2022, 65, 2313-2328; J. Med. Chem. 2025, 68, 17303-17322). PROTAC is a drug development technology that utilizes the ubiquitin-proteasome system to degrade target proteins. PROTAC consists of three parts: an E3 ubiquitin ligase ligand and a target protein ligand. The two active ligands are linked together by a specially designed linker structure, ultimately forming the active form of the triplet PROTAC. In the patient's body, the target protein ligand of the PROTAC binds to the target protein, and the E3 ubiquitin ligase ligand binds to the substrate-binding region of the intracellular E3 ubiquitin ligase. This, through the linker, pulls the target protein closer to the E3 ubiquitin ligase, enabling the UPS system to degrade the target protein, reducing protein levels rather than inhibiting protein function, thus achieving the therapeutic goal. Current research on degradative agents mainly focuses on degrading single proteins such as TRK, ROS1, or ALK, with relatively few reports on multi-target degradative agents. Summary of the Invention
