Infection rates are rising worldwide, highlighting NTM as an increasing threat to public health. There are currently no specific drugs, and the recommended regimens are usually ineffective. This scenario underlines the urgent need to develop new strategies to effectively combat these infections in a more innovative way. However, the development of new drugs can be a lengthy process, often taking more than a decade to identify even a single active compound. Among the new strategies that can expedite this process is the repurposing of approved drugs. In this work, we applied this approach to identify compounds inhibiting iron uptake in <i>Mycobacterium abscessus</i> (<i>Mab</i>). Specifically, we studied the targeting of salicylate synthase, an enzyme that plays a crucial role in the biosynthesis of mycobacterial siderophores necessary for iron acquisition. Performing an <i>in silico</i> virtual screening of three databases against the crystal structure of salicylate synthase, we identified 11 potential ligands. Then, in vitro assays on the recombinant enzyme highlighted three competitive inhibitors, namely fostamatinib, esomeprazole, and hydroxystilbamidine.

Although 2-hydroxy-3-methylanthraquinone (HMA), a natural anthraquinone compound, has demonstrated antitumor activity in various malignancies, its specific role and underlying mechanisms in HCC are not fully understood. This study aimed to evaluate the antitumor effects and molecular mechanisms of HMA in HCC. Human HCC cell lines were treated with HMA, and cell proliferation and apoptosis were assessed using Cell Counting Kit-8 and flow cytometry assays, respectively. A heterotopic xenograft tumor model was established in nude mice to evaluate in vivo tumor growth and weight. Immunohistochemical staining for Ki67 and Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay was performed to assess tumor cell proliferation and apoptosis. Network pharmacology analysis was conducted to predict potential targets of HMA in HCC. Quantitative real-time polymerase chain reaction and Western blotting were used to evaluate mRNA and protein expression levels. Cell migration and invasion were assessed using wound healing and transwell assays. Our data revealed that HMA significantly suppressed cell proliferation, induced apoptosis, and inhibited migration and invasion in both HCC cells and tumor tissues. Mechanistically, HMA downregulated Annexin A5 (ANXA5) expression and inhibited activation of the phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) signaling pathway. Silencing of ANXA5 replicated the inhibitory effects of HMA and further enhanced its pro-apoptotic and anti-invasive activities. Conversely, overexpression of ANXA5 restored PI3K/AKT signaling activity and reversed the inhibitory effects of HMA on HepG2 cell proliferation, migration, and invasion. These reversal effects were abolished by treatment with LY294002, a selective PI3K inhibitor. In summary, HMA suppresses the progression of HCC by targeting ANXA5 and inhibiting the PI3K/AKT signaling pathway, highlighting its potential as a novel therapeutic agent for HCC.</p>\u0000 </div>","PeriodicalId":143,"journal":{"name":"Chemical Biology & Drug Design","volume":"106 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144688014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated the effect of SALL4 on 5-FU resistance in GC cells by bioinformatics analysis, real-time quantitative reverse transcription polymerase chain reaction, cell counting kit-8, colony formation assay, and western blot. The results showed that SALL4 was highly expressed in GC and significantly correlated with the fatty acid oxidation (FAO) pathway. Knockdown of SALL4 resulted in a notable attenuation of cellular proliferative capacity and heightened susceptibility to 5-FU resistance in GC cells, while overexpression of SALL4 enhanced 5-FU resistance. Rescue assays confirmed that SALL4 fostered 5-FU resistance in GC cells by enhancing FAO. Our research confirmed that SALL4 promoted the resistance of GC cells to 5-FU by enhancing the FAO pathway.

Therefore, Zinc finger protein 726 (ZNF726) can be considered an attractive therapeutic target for the treatment of breast cancer. Based on these views, this study aimed to identify potent inhibitors targeting ZNF726 activity utilizing a structure-based molecular docking method. Virtual screening with the LOPAC library led to the identification of zoledronic acid monohydrate as a top-hit compound featuring good docking and MMGBSA scores. Further, zoledronic acid monohydrate was found to inhibit the proliferation potential of breast cancer cells. Ectopic expression of ZNF726 led to an increase in the cholesterol levels of breast cancer cells. Further, this study confirms that zoledronic acid tends to decrease the cholesterol content in ZNF726-overexpressed cells along with an inhibitory effect on breast cancer cell proliferation. Conclusively, these findings suggested that the cholesterol pathway and oncogenic ZNF726 form an interdependent relationship, and therefore, targeting the cholesterol pathway may prove to be a promising strategy to inhibit oncogenic ZNF726 expression in breast cancer. Additionally, this study also reveals nine phytochemicals that might target ZNF726 activity, identified through virtual screening by the IMPPAT library. Three phytochemicals (Swertiamacroside, Terflavin A, and N-(3-Carboxy-2,3-dihydroxypropyl)-4-((carboxymethyl)amino) threonine) out of the nine phytochemicals are still unknown for their anticancer role which needs further exploration.
