Organotin(IV) complexes are promising chemotherapeutics due to their structural versatility and bioactivity, while vitamins such as Vitamin D (VD) and Vitamin E (VE) exhibit antiproliferative, anti-inflammatory, and antioxidant properties, making them valuable candidates for combination therapy. <b>Methodology</b>: In this study, six novel organotin(IV) dithiocarbamate complexes [LMe<sub>3</sub>Sn (Complex 1), LBu<sub>3</sub>Sn (Complex 2), LPh<sub>3</sub>Sn (Complex 3), LMe<sub>2</sub>SnCl (Complex 4), LBu<sub>2</sub>SnCl (Complex 5), and L<sub>2</sub>Me<sub>2</sub>Sn (Complex 6), where L = (E)-4-styrylpiperazine-1-carbodithioate], were synthesized and characterized by FT-IR, <sup>1</sup>H-, <sup>13</sup>C-NMR, and elemental analysis. <b>Results</b>: Structural studies confirmed penta- and hexacoordination geometries. In silico docking against six BC-related proteins identified Complexes 2 and 4 with both vitamins as promising candidates, exhibiting strong binding affinities, with stable interaction profiles. However, integration of pharmacokinetic, antioxidant, and anti-inflammatory analyses highlighted Complex 4 with both vitamins as the most potent candidate owing to its superior ADME characteristics and balanced biological properties. Subsequent in vitro assays confirmed these findings, as Complex 4 demonstrated strong cytotoxic activity against both MCF-7 (>1.16-fold) and MDA-MB-231 (>1.46-fold) cell lines, surpassing the efficacy of cisplatin. Remarkably, co-administration of VD or VE with Complex 4 further enhanced its anticancer potential, with Chou-Talalay combination index values < 1 (0.66-0.91) indicating a synergistic interaction. <b>Conclusions</b>: Collectively, these results identify Complex 4 as a promising lead compound, and its synergistic activity with natural vitamins may promote cell death, likely through apoptosis induction and modulation of oxidative stress, underscoring its potential as an effective and less toxic therapeutic strategy for breast cancer management.</p>","PeriodicalId":20198,"journal":{"name":"Pharmaceuticals","volume":"19 4","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13119188/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147819759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
