Enhanced Oral Bioavailability and Biodistribution of Voriconazole through Zein-Pectin-Hyaluronic Acid Nanoparticles.

Nanotechnology-based drug delivery systems offer a solution to the pharmacokinetic limitations of voriconazole (VRC), including saturable metabolism and low oral bioavailability. This study developed zein/pectin/hyaluronic acid nanoparticles (ZPHA-VRC NPs) to improve VRC's pharmacokinetics and biodistribution. The nanoparticles had a spherical morphology with an average diameter of 268 nm, a zeta potential of -48.

Enhancing Oral Bioavailability and Brain Biodistribution of Perillyl Alcohol Using Nanostructured Lipid Carriers.

Perillyl alcohol (POH), a bioactive monoterpenoid derived from limonene, shows promise as an antitumor agent for brain tumor treatment. However, its limited oral bioavailability and inadequate brain distribution hinder its efficacy. To address these challenges, this study developed nanostructured lipid carriers (NLCs) loaded with POH to improve its brain biodistribution.

Mucoadhesive nanoemulsion enhances brain bioavailability of luteolin after intranasal administration and induces apoptosis to SH-SY5Y neuroblastoma cells.

Neuroblastoma is the most frequently diagnosed extracranial solid tumor in children and accounts for 7 % of all childhood malignancies and 15 % cancer mortality in children. Luteolin (LUT) is recognized by its anticancer activity against several types of cancer. The aim of this study was to prepare chitosan-coated nanoemulsion containing luteolin (NECh-LUT), investigate its potential for brain delivery following intranasal administration, and to evaluate its cytotoxicity against neuroblastoma cells.
