Their ability to chelate biologically relevant metal ions such as vanadium, copper, zinc and ruthenium enables the formation of stable coordination complexes with significant cytotoxic and pro-apoptotic activity. This review highlights the structural characteristics of hydroxypyranone ligands and their influence on the pharmacological properties of metal complexes. Notable systems, including bis(maltolato)oxovanadium(IV) (BMOV), VO–phen complex(Metvan) and Ru(II)–maltol complexes, have shown higher selectivity and lower systemic toxicity compared to classical chemotherapeutic agents such as cisplatin. The most important mechanisms of action include interaction with DNA, the formation of reactive oxygen species (ROS), mitochondrial dysfunction and the inhibition of enzymes. This review highlights the antitumor activity of copper(II), vanadium(IV/V), and ruthenium(II) complexes against hepatocellular and colorectal cancer cell lines. The review highlights the importance of rational ligand design, redox activity and metal ion selection for optimizing the therapeutic index of metallopharmaceuticals. Future perspectives point to the integration of these compounds into advanced drug delivery platforms and their evaluation in preclinical and clinical settings. This review emphasises the therapeutic importance of hydroxypyranone–metal complexes as selective and less toxic alternatives to platinum drugs. It provides new insights into their structure–activity relationships and supports their development as promising candidates for targeted cancer therapy.</p></div>","PeriodicalId":699,"journal":{"name":"Medicinal Chemistry Research","volume":"34 8","pages":"1616 - 1630"},"PeriodicalIF":3.1,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145161557","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}

Although EGFR-targeting small-molecule inhibitors are clinically available, their limited efficacy and acquired resistance pose major challenges. In this study, we designed and synthesized a novel class of dual proteolysis-targeting chimeras (PROTACs) incorporating the natural product derivative Potassium Dehydroandrographolide Succinate (PDS) as the protein of interest (POI) ligand. PDS was selected as the POI ligand due to its structural similarity to andrographolide, a natural compound known to inhibit EGFR signaling, suggesting that PDS may retain EGFR-binding potential despite lacking direct anti-tumor reports. Unlike conventional PROTACs, these molecules feature two CRBN E3 ligase ligands symmetrically attached via distinct linkers, thereby enhancing the likelihood of ternary complex formation and promoting more efficient EGFR degradation. Among the synthesized compounds, DP6 exhibited the most potent anti-proliferative activity in MCF-7 cells, with a 3.8-fold improvement over the parent PDS molecule. Western blotting confirmed that DP6 induced concentration-dependent EGFR degradation via the ubiquitin–proteasome system, suppressed downstream JAK2-STAT3 signaling, and promoted apoptosis. This study not only demonstrates the feasibility of utilizing structurally modified natural products as POI ligands, but also introduces a unique dual-ligand PROTAC architecture that may provide enhanced degradation potency for traditionally “undruggable” targets.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":699,"journal":{"name":"Medicinal Chemistry Research","volume":"34 8","pages":"1695 - 1713"},"PeriodicalIF":3.1,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145171642","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}
