The escape of gastrointestinal stromal tumor cells from senescence leads to cellular immortality and uncontrolled proliferation. Therefore, inducing senescence is considered a crucial approach for preventing the progression of gastrointestinal stromal tumors. Sunitinib, a tyrosine kinase inhibitor, has been approved as a drug for treating gastrointestinal stromal tumors and renal cell carcinoma. However, it remains unclear whether Sunitinib exerts a protective effect by inducing cellular senescence in gastrointestinal stromal tumor cells. <b>Methods:</b> Cells were treated with Sunitinib. Cellular senescence was assessed using the senescence-associated β-galactosidase (SA-β-gal) staining assay and a telomerase activity kit. Gene and protein expression were measured using real-time PCR and western blot analysis. <b>Results and Discussion:</b> We found that Sunitinib reduced cell viability in GIST-882 cells. Additionally, Sunitinib induced oxidative stress and DNA damage by increasing mitochondrial reactive oxygen species (ROS), 8-hydroxy-2'-deoxyguanosine (8-OHdG), and the phosphorylated form of histone H2AX (γH2AX). The SA-β-gal staining assay revealed that Sunitinib induced cellular senescence in GIST-882 cells by reducing telomerase activity and the expression of human telomerase reverse transcriptase (hTERT). Interestingly, the presence of the antioxidant N-acetyl-L-cysteine (NAC) abolished the effects of Sunitinib on cellular senescence, suggesting the involvement of ROS in this process. Further analysis showed that Sunitinib upregulated the expression of acetylated p53 and p21 while downregulating the expression of silent information regulator sirtuin 1 (SIRT1). Notably, overexpression of SIRT1 prevented Sunitinib-induced cellular senescence in GIST-882 cells, suggesting that SIRT1 plays a key role in this process. <b>Conclusions:</b> Taken together, our findings suggest that Sunitinib induces a “therapy-induced senescence” effect in gastrointestinal stromal tumors by inhibiting SIRT1.</p>","PeriodicalId":758,"journal":{"name":"Russian Journal of Bioorganic Chemistry","volume":"51 2","pages":"743 - 754"},"PeriodicalIF":1.1,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143786361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, new and more effective methods of cancer therapy are in demand. As monoclonal antibody-based immunotherapy has already shown its effectiveness, antibody-drug conjugates (ADC), one of its successful variants, have significant and not yet fully realized potential. ADCs are monoclonal antibodies bound to cytotoxic drugs through linkers. In many clinical trials and already in standard clinical practice, ADCs have demonstrated significant advantages over the combination therapy with unmodified antibodies and chemotherapeutic drugs. Due to new achievements in the field of molecular immunology and biotechnology, the potential of ADCs is assessed as a breakthrough, which will allow ADCs to become the most sought-after anticancer drugs in the coming years. Owing to ADCs it has become possible to deliver drugs to tumor cells in a targeted manner without significant toxic effects on healthy tissues and organs. To date, 15 ADC drugs have been approved worldwide for use in clinic, and more than a hundred more drugs of this class are at various stages of clinical trials. At the same time, ADC therapy is associated with certain side effects and limited efficacy. Therefore there is a need to develop more advanced conjugates.

The action of HlyII leads to cell lysis due to pore formation on membranes. Monoclonal antibodies against the large <i>C</i>-terminal fragment (Met225–Ile412, HlyIILCTD) of <i>B. cereus</i> HlyII were obtained by the hybridoma technology using the recombinant soluble form of HlyIILCTD as an antigen.

The antibodies most effectively inhibited the hemolysis of erythrocytes, induced B-771 HlyII, the sequence of which contains Pro324. It was shown that the antibody interacts with the pores formed in the RBC membranes, thereby blocking the possible release of intracellular contents. <b>Methods:</b> HlyII and its mutant forms were obtained using recombinant <i>E. coli</i> BL21(DE3) producer strains.

The substitution of Pro324 by Leu in the primary sequence of HlyII affected the neutralizing ability of the antibody. The LCTD-83 antibody less effectively interacts with the full-length toxin than with HlyIILCTD, which is evidenced by the fact that pore formation is accompanied by a change in the toxin conformation.

Structure-activity relationship analysis was derived based on <i>in vitro</i> cytotoxicity and <i>in silico</i> ADME properties. <i>In vitro</i> studies were performed to evaluate the mechanisms underlying the cytotoxic and other anticancer capabilities, including morphological assessments, apoptosis assays, caspase assays, and cell migration/invasion assays. Western blot analysis examined the modulation of the PI3K/AKT/<i>m</i>TOR pathway. PI3K kinase inhibition assays and docking studies confirmed the inhibitory effects and binding affinity. <b>Results and Discussion:</b> Compounds (<b>XIf</b>) and (<b>XIi</b>) demonstrated significant cytotoxic potency against breast cancer cell lines, with compound (<b>XIi</b>) showing superior capabilities. Compound (<b>XIi</b>) induced a dose-dependent increase in apoptosis, particularly at 2 × IC<sub>50</sub>, and activated both intrinsic and extrinsic apoptotic pathways. It also suppresses cell migration and invasion, which are key processes in cancer progression. Western blot analysis revealed significant inhibition of the PI3K/AKT/<i>m</i>TOR pathway by compound (<b>XIi</b>), especially in the presence of estrogen, suggesting potential synergy with tamoxifen in estrogen receptor-positive breast cancer. The PI3K kinase inhibition assay showed dose-dependent inhibition of PI3K-α by compound (<b>XIi</b>), comparable to PI-103 at higher concentrations. Docking studies indicated a strong binding affinity of compound (<b>XIi</b>) to the PI3Kα isoform. <b>Conclusions:</b> The study identified andrographolide derivatives, especially compound (<b>XIi</b>), as promising agents against breast cancer, warranting further exploration of their therapeutic potential.</p>","PeriodicalId":758,"journal":{"name":"Russian Journal of Bioorganic Chemistry","volume":"51 2","pages":"601 - 628"},"PeriodicalIF":1.1,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143786516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
