Abstract
Description
An aromatic heterocyclic SLC7A11 inhibitor and its preparation method and use Technical Field
[0001] The present invention relates to a SLC7A11 inhibitor, a preparation method, and uses thereof. The inhibitor and a pharmaceutical composition containing the same can be used to prevent and / or treat SLC7A11-related diseases or conditions. Background Art
[0002] System xC - It is a sodium-independent antiporter that releases intracellular glutamate and takes up extracellular cystine in a 1:1 ratio (Bannai S (1986) Exchange of cystine and glutamate across plasma membrane of human fibroblasts. J Biol Chem 261:2256-2263). It is involved in glutathione biosynthesis and antioxidant defense. It is overexpressed in a variety of human cancers and is associated with poor prognosis, such as pancreatic cancer, liver cancer, glioma, renal cancer, lung cancer, mesothelioma, and uveal melanoma (Badgley MA, et al. Science. 2020. PMID: 32241947). It consists of two disulfide-linked subunits: the heavy chain subunit solute carrier family 3 member 2 (SLC3A2; also known as CD98 or 4F2hc) and the light chain subunit solute carrier family 7 member 11 (SLC7A11). Studies have shown that tumor cells promote tumor growth by inhibiting ferroptosis by overexpressing SLC7A11. Ferroptosis is a new form of regulated cell death that is iron-dependent and induced by excessive lipid peroxidation.
[0003] In 2020, the number of new cases of pancreatic ductal adenocarcinoma (PDAC) reached 420,000, and the number of deaths reached 410,000. It is estimated that by 2030, pancreatic cancer may become the second leading cause of death among malignant tumors. PDAC is a lethal cancer that is resistant to traditional therapies, with a 5-year survival rate of <9%. Over 90% of PDAC cases carry KRAS mutations, which both promote proliferation and alter cellular metabolism. Mutant KRAS signaling leads to increased production of reactive oxygen species (ROS), which damage cellular components. To compensate, PDAC cells upregulate metabolic programs that use cysteine-derived metabolites, such as glutathione, to detoxify ROS (DeNicola GM et al., Oncogene-induced Nrf2 transcription promotes ROS detoxification and tumorigenesis. Nature 475, 106-109 (2011). [PubMed: 21734707]). Most cellular cysteine is obtained through the system xC-antiporter, which exchanges extracellular oxidized cysteine (cystine) for intracellular glutamate. However, germline deletion of the system xC-gene SLC7A11 is well tolerated in unstressed mice (Sato H et al., Redox imbalance in cystine / glutamate transporter-deficient mice. J. Biol. Chem 280, 37423-37429 (2005). [PubMed: 16144837]), indicating that the basal cystine import requirement of normal cells is low.Studies have shown that SLC7A11 deletion via CRISPR-Cas9 has been shown to induce ferroptosis in cultured PDAC cells and slow the engraftment and growth of xenografts (Daher B et al., Genetic Ablation of the Cystine Transporter xCT in PDAC Cells Inhibits mTORC1, Growth, Survival, and Tumor Formation via Nutrient and Oxidative Stresses. Cancer Res. 79, 3877-3890 (2019). [PubMed: 31175120]), and systemic xC-inhibition has been shown to limit the growth of lymphoma xenografts, inducing lipid oxidation signatures and other indicators of ferroptosis (Zhang Y et al., Imidazole Ketone Erastin Induces Ferroptosis and Slows Tumor Growth in a Mouse Lymphoma Model. Cell Chem. Biol. 26,623-633e629(2019).[PubMed:30799221]).
[0004] Most pancreatic cancer patients are diagnosed at an advanced stage, and currently lack effective therapeutic agents. Most pancreatic cancer treatments, including the standard treatment gemcitabine and novel molecularly targeted therapies, have demonstrated impressive activity against PDAC cells in culture and in some preclinical animal models, but have shown little success in the clinic. This poor prognosis is primarily due to the drug-refractory nature of PDAC, which results from inherent chemoresistance and physical barriers to drug delivery. A dense fibrotic microenvironment drives these mechanisms. Fibrosis alters tumor vasculature, physically hindering drug access and creating a harsh, hypoxic, and nutrient-deprived microenvironment that promotes a more metastatic and chemoresistant mesenchymal phenotype. Pancreatic cancer has a defective vasculature that severely compromises drug delivery. The architects of the pancreatic cancer microenvironment are cancer-associated fibroblasts (CAFs). On the one hand, CAFs are activated by hypoxia signals released by PDAC cells, leading to a self-perpetuating cycle of excessive extracellular matrix (ECM) protein deposition, thereby producing fibrosis. On the other hand, CAFs transmit pro-survival signals to PDAC cells, thereby promoting PDAC cell survival and epithelial-to-mesenchymal transition (DOI: 10.3389 / fphys.2014.00141; DOI: 10.1002 / ags3.12225; DOI: 10.1016 / j.trecan.2019.09.010).
[0005] Based on the aforementioned pathological characteristics of pancreatic cancer, effective drug efficacy requires targeting both pancreatic cancer cells and pancreatic cancer-associated fibroblasts. Studies have demonstrated that high expression of SLC7A11 in the stroma of PDAC tumors, rather than in tumor cells, independently correlates with poor prognosis and overall survival. Knockdown of SLC7A11 in CAFs inhibits their proliferation. Knockdown of SLC7A11 in CAFs significantly inhibits the viability of pancreatic cancer cells and CAFs in co-culture. Knockdown of SLC7A11 in pancreatic cancer cells has no significant effect on tumor growth. However, knockdown of SLC7A11 in both PDAC cells and CAFs significantly inhibits tumor growth, metastasis, and fibrosis. Studies have demonstrated that cancer-associated fibroblasts in pancreatic ductal adenocarcinoma determine the response to SLC7A11 inhibition (Doi:10.1158 / 0008-5472.CAN-20-2496). New drugs are urgently needed to improve patient survival and quality of life. SLC7A11 is also associated with a variety of diseases, including tumors such as liver cancer, osteosarcoma, and glioma; chronic diseases such as fatty liver disease, cirrhosis, liver fibrosis, pulmonary fibrosis, and diabetic skin lesions; and neurodegenerative diseases such as amyotrophic lateral sclerosis, Parkinson's disease, and Alzheimer's disease. Therefore, the development of highly active small molecule SLC7A11 inhibitors has significant social and market value.
