Description

A PARP1 and ULK1 dual-target inhibitor and its preparation method and application Technical Field

[0001] The present invention belongs to the field of medicine, and specifically relates to a PARP1 and ULK1 dual-target inhibitor, and a preparation method and application thereof. Background Art

[0002] Poly(ADP-ribose) polymerase (PARP) is a multifunctional post-translational protein modification enzyme present in most eukaryotic cells. PARP family has 18 isoforms. Among them, PARP-1 accounts for the largest proportion and plays a major role in DNA damage repair [Peraltaleal A, et al., Free Radical Biology and Medicine 2009, 47(1):13-26].

[0003] Among DNA damage, the most serious damage is single-strand break (SSB) and double-strand break (DSB), among which single-strand break is more common. If these breaks cannot be repaired in time and accurately, the genome will become unstable, leading to cancer or directly leading to cell death. In order to maintain normal physiological functions, cells have a variety of DNA damage detection and repair mechanisms. The repair of single-strand break damage mainly depends on PARP, among which PARP1 plays more than 90% of the function [Langelier M, et al., Nucleic Acids Research 2014, 42(12):7762-7775]. As for double-strand break, although the occurrence is rare, the consequences are serious. If it cannot be repaired in time, the cell DNA will become unstable and eventually lead to death. Homologous recombination (HR) is a high-fidelity, error-free repair method for DNA double-strand break repair. The proteins involved in this repair include BRCA, ATM, RAD51, etc. The most well-known is BRCA protein. People carrying familial hereditary BRCA1 / 2 mutations have a significantly increased risk of malignant tumors, especially breast cancer and ovarian cancer. BRCA1 / 2 are key proteins involved in the homologous recombination repair of double-strand breaks. BRCA1 / 2 mutations impair DNA double-strand break repair, leading to genomic instability and, subsequently, cancer. Due to the cell's survival mechanism, impaired double-strand break repair makes cells more dependent on PARP-driven single-strand break repair. Compared to tumor cells with intact BRCA function, BRCA-deficient tumor cells are 100 times more sensitive to PARP inhibitors. The successful use of PARP inhibitors in BRCA-deficient cancer patients is a classic example of "synthetic lethality" in the DNA damage repair response (DDR) [Bryant H E., Nature 2005, 434(7035):913-917; Farmer H, et al., Nature 2005, 434(7035):917-921]. Currently, the PARP inhibitors that have been successfully marketed include Olaparib, Rucaparib, Niraparib, and Talazoparib.

[0004] Autophagy is a conserved intracellular degradation process that determines which organelles, proteins, and invading microorganisms are degraded by lysosomes. This conserved process is required for cellular responses to nutrient deprivation and other stresses, in addition to being required for proper cell and tissue homeostasis during embryonic development and for defense against pathogens. Defects in the autophagy pathway have been implicated in several human pathologies, including infectious diseases, neurodegenerative disorders, and cancer.

[0005] Autophagy is a multi-step pathway initiated by the ULK (unc-51-like autophagy-activating kinase) pre-initiation complex, which is composed of unc-51-like autophagy-activating kinase 1 (ULK1) or its homolog ULK2, autophagy-related protein 13 (ATG13), ATG101, and focal adhesion kinase (FAK) family interacting protein (FIP200) [Hosokawa N., et al., Autophagy 2009, 5:973-979; Ganley IG, et al., J Biol Chem 2009, 5:973-979]. Autophagy is activated by AMPK under stress conditions and inhibited by mTOR under non-stress conditions [Laplante M, et al., Cell 2012, 149:274-293]. AMPK activates autophagy through two mechanisms: first, it inhibits mTOR activity by phosphorylating the mTOR complex components raptor and TSC2; second, it activates ULK1 / 2 by directly phosphorylating multiple sites in the N-terminus of ULK1 / 2 to the mTOR phosphorylation site. Conversely, mTOR inhibits autophagy by directly phosphorylating and inhibiting ULK1 / 2 function.

[0006] As the only serine / threonine kinase in the autophagy signaling pathway, ULK1 / 2 plays a key role in autophagy by phosphorylating three proteins in the ULK1 / 2 pre-initiation complex (ATG13, ATG101 and FIP200)9-11 and the downstream Beclin1 initiation protein complex (Beclin1, VPS34, ATG9 and ATG16L1) [Papinski D, et al., Mol. Cell 2014, 53:471-483; Papinski D, et al., J Mol Biol 2016, 428:1725-1741; Egan D, et al., Mol Cell 2015, 59:285-297; Alsaadi R, EMBO Rep. 2019, 20:No.e46885].

[0007] Knocking out ULK1 or using small molecule ULK1 inhibitors can effectively inhibit autophagy, induce apoptosis, and inhibit tumor cell growth [Si-Tu Xue, et al., Autophagy 2020, 16(10): 1823-1837; Huiyu R, et al., J. Med. Chem. 2020, 63: 14609-14625].

[0008] Parp1 inhibitor-induced autophagy is the main cause of primary resistance to Parp1 inhibitors. The combined use of Parp1 inhibitors and autophagy inhibitors has shown strong synergistic anti-cancer effects in different tumors [Pai Bellare G, et al., Cancer 2021, 124: 1260-1274; Fu XT, et al., Cancer Cell Int. 2019, 19: 71; Luo T, et al., Autophagy 2016, 12: 1355-1371; Lu S, et al., Cell Death Dis. 2018, 9: 646; Liu Y, et al., AMB Expr 2019, 9: 108; Janice M SO, et al., Cancer 2020, 126: 894-907].

[0009] Therefore, developing a dual-target inhibitor that can simultaneously inhibit PARP1 and ULK1 will provide a new, safe and effective anti-cancer drug. Summary of the Invention
