Fabrication and Evaluation of Anticancer Potential of Eugenol Incorporated Chitosan-Silver Nanocomposites: In Vitro, In Vivo, and In Silico Studies

Beyond Chemistry: Investigating the Physical, Pharmacological, and Computational Aspects of Polyoxometalate Integrated Solid Lipid Nanoparticles for Cancer Treatment

Purpose

The solid lipid nanoparticles of transitional metal complexes (POMs) were prepared with natural lipids with the aim of developing a safer therapeutic approach for cancer treatment.

Methods

Natural lipids were used to create solid lipid nanoparticles containing transitional metal complexes (POMs).

Results

The nanoparticles had displayed appreciable entrapment and loading percentage of P5W30. The zeta capacitance was measured to be -32.57±6.44 mV with average particle dimension of 160.5±8.61 nm and polydispersity index (PDI) of around 0.3814±0.096. The effectiveness of P5W30-BW-SLNs in inhibiting the growth of HeLa cells was found to be higher (IC50 = 3.02±2.14 µg/mL) compared to pure P5W30 (IC50 = 7.93±5.08 µg/mL). Further examinations of DNA damage were made through comet test and flow cytometry techniques. The assessment of tumor regression and survival was conducted, and comparison was recorded. The P5W30-BW-SLNs resulted in a 72.91% increase in survival rates and a reduction in tumor burden by 2.967±0.543%. Moreover, the computational findings demonstrate a strong connection with the actual data, providing a plausible explanation for the notable chemopreventive efficacy of POM against HeLa cell lines.

Conclusion

The study's findings might pave the way for a more efficient delivery system in cancer treatment.

Synthesis, characterization, pharmacological and computational evaluation of hyaluronic acid modified chebulinic acid encapsulated chitosan nanocomposite for cancer therapy

The purpose of this study was to produce hyaluronic acid customized nanoparticles with chitosan for the delivery of chebulinic acid (CLA) to enhance its anticancer potential against breast cancer. A significant portion of CLA was encapsulated (89.72 ± 4.38 %) and loaded (43.15 ± 5.61 %) within hybrid nanoparticles. The colloidal hybrid nanoparticles demonstrated a polydispersity index (PDI) of about 0.379 ± 0.112, with zeta capacitance of 32.69 ± 5.12 (mV), and an average size of 115 ± 8 (nm). It was found that CLA-CT-HA-NPs had stronger anticancer effects on MCF-7 cells (IC50 = 8.18 ± 3.02 μM) than pure CLA (IC50 = 17.15 ± 5.11 μM). The initial cytotoxicity findings were supported by additional investigations based on comet assay and flow cytometry analysis. Tumor remission and survival were evaluated in five separate groups of mice. When juxtaposed with pure CLA (3.17 ± 0.419 %), CLA-CT-HA-NPs improved survival rates and reduced tumor burden by 3.76 ± 0.811(%). Furthermore, in-silico molecular docking investigations revealed that various biodegradable polymers had several levels of compatibility with CLA. The outcomes of this study might potentially served as an effective strategy for delivering drugs in the context of breast cancer therapy.
