Cholesterol-Conjugate as a New Strategy to Improve the Cytotoxic Effect of 5-Fluorouracil on Liver Cancer: Impact of Liposomal Composition.

Purpose: Hepatocellular carcinoma (HCC) is a common liver malignancy, which has a low survival rate of all cancers. 5-fluorouracil (5-FU) is clinically recognized to treat HCC. However, the success of this therapy is highly limited due to rapid clearance and non- selective distribution.

Novel docetaxel chitosan-coated PLGA/PCL nanoparticles with magnified cytotoxicity and bioavailability.

In the present study, docetaxel (DTX)-loaded poly(lactic-co-glycolic acid) (PLGA) and polycaprolactone (PCL) nanoparticles were successfully prepared and coated with chitosan (CS). The prepared nanoparticles (NPs) were evaluated for their particle size, zeta potential, particle morphology, drug entrapment efficiency (EE%), and in vitro drug release profile. The anticancer activity of DTX-loaded NPs was assessed in human HT29 colon cancer cell line utilizing MTT assay.

Di-Block PLCL and Tri-Block PLCLG Matrix Polymeric Nanoparticles Enhanced the Anticancer Activity of Loaded 5-Fluorouracil.

In the current study, 5-FU-loaded nanoparticles (NPs) were prepared using polylactic-co-glycolic acid (PLGA), polycaprolactone (PCL), di-block poly lactide-co-caprolactone (PLCL) and tri-block poly L-lactide-co-caprolactone-co-glycolide (PLCLG). The influence of these polymers on the particle sizes, morphology, drug loading, and in vitro drug release was investigated. The anticancer activity was assessed utilizing MTT assay in three human cancer cell lines of different tissue origin; brain (Daoy), liver (HepG2), and colorectal (HT29) using suitable negative and positive controls.
