Abstract
Introduction: Colorectal cancer is an important cause of cancer-related mortality, necessitating innovative therapies to improve efficacy and reduce side effects. This study explores the potential of Cisplatin and Rutin-loaded nanoliposomes (Cis-NLs and Rut-NLs) for anti-colorectal cancer activity.
Methods: Cis-NLs and Rut-NLs were prepared using thin-film hydration, achieving encapsulation efficiencies of 95.5% and 62.5%, respectively. Drug release studies revealed controlled profiles, with Cis-NLs showing a complete release (100%) and Rut-NLs reaching 23.48% over 48 hours. Stability assessments demonstrated minimal changes in size, polydispersity index (PDI), and zeta potential over three months. Encapsulation efficiency decreased slightly for Cis-NLs (92.87%) and significantly for Rut-NLs (26.55%). Several tests were performed to evaluate the biological activity of this combination on colorectal cancer cells and HDF cells to check its selectivity.
Results: In vitro cytotoxicity studies on HT29 colorectal cancer cells revealed IC50 values of 1.72 μg/mL for free Cisplatin, 2.35 μg/mL for Cis-NLs, >100 μg/mL for free Rutin, and 63.33 μg/mL for Rut-NLs. A combination of Cis-NLs and Rut-NLs reduced the IC50 to 2.2 μg/mL. Selective toxicity evaluation using human dermal fibroblasts showed an IC50 of 79.24 μM for cisplatin, reduced to 63.3 μM in Cis-NLs, with Rut-NLs demonstrating negligible toxicity.
Discussion: Wound healing assays confirmed significant inhibition of cell migration, with wound closure reduced from 62.41% in controls to 34.35% in treated groups. Utilizing nanotechnology, liposomal formulations were synthesized to enhance drug delivery and therapeutic synergy.
Conclusion: These results highlight the potential of Cisplatin and Rutin-loaded nanoliposomes as a combination therapy for colorectal cancer.
