Abstract
Breast cancer is the most commonly diagnosed malignancy among women worldwide, with treatment often challenged by genetic and non-genetic resistance mechanisms. This study presents a novel, eco-friendly approach for synthesizing gold nanoparticles (AuNPs) using the ethyl acetate extract of Piper betle var. Mysuru, an agriculturally significant plant known for its bioactive phytochemicals. This green synthesis method not only minimizes environmental impact but also enhances the therapeutic potential of the resulting nanoparticles. Characterization of the AuNPs revealed their spherical, nanocrystalline nature with a face-centered cubic lattice and diameters ranging from 14 to 34 nm (25 nm average). The AuNPs demonstrated remarkable cytotoxicity against MCF-7 breast cancer cell lines, achieving an IC50 value of 9.06 ± 0.51 μg/mL, outperforming plant extracts and conventional therapies. Hemolytic assays further confirmed their safety, with minimal hemolysis (8.67%), supporting their potential for safe systemic circulation. The study's novelty is identifying decoside, a bioactive compound in P. betle, as a potent inhibitor of the EGFR signaling pathway. Molecular docking and dynamic simulations revealed strong binding interactions between decoside and target proteins, disrupting pathways critical to cancer cell proliferation. This work highlights the potential of P. betle-mediated AuNPs as a sustainable, scalable, and highly effective solution for breast cancer therapy. Their affordability, eco-friendliness, and enhanced therapeutic efficacy underscore their promise for clinical applications and large-scale production, paving the way for advanced cancer therapeutics with reduced side effects.
期刊介绍:
All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
