Description

Technical Field

[0001] The present invention relates to the field of medical technology, and in particular to an anti-tumor composition and application thereof. Background Art

[0002] Tumors are neoplasms formed by the abnormal proliferation and differentiation of cells in the body. They include both benign and malignant tumors (cancer). Benign tumors typically grow slowly, have clear boundaries, do not invade surrounding tissues, and have no metastatic potential. Malignant tumors, on the other hand, grow rapidly, can invade surrounding tissues and organs, and metastasize to distant sites. Malignant tumors are one of the major threats to human health, and their occurrence is related to multiple factors, including genetics, environment, and lifestyle.

[0003] Treatment options for cancer primarily include surgery, chemotherapy, radiotherapy, targeted therapy, and immunotherapy. With the continuous advancement of medical technology, new treatments and approaches continue to emerge, bringing more hope and options to cancer patients.

[0004] Mitophagy is a pathway of intracellular autophagy. Under normal physiological conditions, it helps cells eliminate aging and diseased mitochondria by selectively degrading damaged mitochondria. It is a conserved biological self-defense mechanism for maintaining intracellular homeostasis. When mitochondria become damaged or diseased due to various factors, mitochondrial membrane permeability and potential change, inducing PTEN-induced putative kinase 1 (PINK1) and Parkin E3 ubiquitin ligase, which activate downstream biochemical responses. Under normal physiological conditions, PINK1 is rapidly degraded after targeting mitochondria. However, when mitochondria are damaged or undergo pathological changes, PINK1 cannot enter mitochondria due to changes in mitochondrial membrane permeability and electrical potential. Instead, PINK1 is anchored to the outer mitochondrial membrane. Through its phosphorylase activity, PINK1 phosphorylates and activates ubiquitin and the ubiquitin-like domain of Parkin, leading to their accumulation around mitochondria. This further recruits autophagy-related receptors such as NDP52 and optineurin (OPTN), which activate microtubule-associated protein 1 light chain 3 (LC3), particularly the conversion of LC3B-I to lipidated LC3B-II. Simultaneously, autophagy-related receptors promote the formation of numerous mitophagosomes, the primary sites for contact and fusion between mitochondria and organelles such as the endoplasmic reticulum and lysosomes, influencing the final fate of mitophagosomes.

[0005] Appropriate levels of mitophagy are a survival strategy for tumors. In extreme situations where tumors attempt to resist chemotherapeutic drug killing, anti-tumor immunity, apoptosis caused by elevated levels of oxygen free radicals (ROS), nutrient deficiency, and hypoxia, appropriate mitophagy is a self-protective mechanism by which tumor cells utilize limited energy to eliminate harmful or damaged mitochondria, thereby mitigating apoptotic cell death caused by excessive mitochondrial damage. However, excessive mitophagy depletes mitochondria and is detrimental to tumor cell survival. Furthermore, abnormal mitophagy signaling pathways in tumor cells are closely linked to events such as mitochondrial-induced apoptosis. When metabolic stress caused by drug killing, DNA damage, inflammation, hypoxia, and nutrient deficiency exceeds a certain threshold or triggers an abnormal mitophagy switch, mitophagy can be exacerbated, potentially leading to cell death. For example, the effects of chemotherapeutic drugs and targeted molecular therapies can lead to irreversible mitophagy, ultimately causing cell death. Therefore, proper mitochondrial autophagy is an important pathway for tumor cell survival and drug resistance, while excessive mitochondrial autophagy causes excessive mitochondrial damage, which can lead to cell apoptosis or even death.

[0006] Targeting mitophagy is an emerging area of ​​drug development for chemotherapy sensitization, but it is currently limited to basic research. Therefore, identifying clinical drugs that regulate mitophagy as combination therapies for chemotherapy sensitization is expected to rapidly translate basic research ideas into clinical applications.

Analysis by DrugComb platform showed that the LOEWE synergy scores of epirubicin and CCCP were (9.61, 18.68, 8.84); the LOEWE synergy scores of epirubicin and olaparib were (5.60, 9.25, 8.85); and the LOEWE synergy scores of epirubicin and ketoconazole were (6.72, 7.68, 6.13). This indicates that epirubicin can produce a synergistic effect with the three mitophagy activators ( Figure 5 ).

[0070] 5. Analysis by DrugComb platform showed that the HSA synergy scores of epirubicin and CCCP were (13.39, 12.74, 11.65); the HSA synergy scores of epirubicin and olaparib were (11.97, 9.35, 14.17); and the HSA synergy scores of epirubicin and ketoconazole were (9.60, 10.90, 9.95).
