Preparation, Characterization, and Anticancer Activity of PEGylated Nano Liposomal Loaded with Rutin against Human Carcinoma Cells (HT-29).

The abstract discusses the development of rutin-loaded nanoliposomes and their anti-colorectal cancer activity against human carcinoma cells (HT-29). The study characterizes the nanoliposomes using the thin-film hydration method and analyzes their size, charge, and polydispersity index. The encapsulation efficiency and drug loading ability of rutin at different concentrations were investigated. The nanoliposomes were found to be stable for up to one month at 4 °C and showed sustained drug release for up to 24 h. The anti-cancer activity of the rutin-loaded nanoliposomes was found to be concentration-dependent and significantly improved compared to free rutin. PEGylated nanoliposomes with rutin (1.8 mg/ml) showed the highest encapsulation efficiency and drug loading ability, along with improved selectivity against cancer cells. Overall, the study provides important insights into the potential use of rutin-loaded nanoliposomes for the treatment of colorectal cancer.
