Purpose: Colon adenocarcinoma is the most common form of gastro intestinal tract cancer, predominantly in ageing population. Chemotherapy with 5-Fluorouracil and oxaliplatin is an indispensable treatment regimen, nevertheless having limitation of systemic toxicity and lower therapeutic index. The present study is based on evaluation of anti-proliferative potential, pharmacokinetics parameters, safety profile, biodistribution and efficacy of 5-FU/oxaliplatin loaded lactoferrin nanoparticles in cell lines and wistar rats in order to overcome the above limitation.
Methods: Nanoparticles were prepared by Water-in-oil process. The anti-proliferative efficacy and mode of cellular entry was evaluated in COLO-205 cells. The pharmacokinetics and biodistribution analysis were performed in healthy rats while efficacy and safety assay were performed in ACF induced rats.
Results: 5-FU and oxaliplatin loaded nanoparticles shows enhanced antiproliferative activity as compare to free drugs in COLO-205 cells. Lactoferrin nanoparticles also improve the pharmacokinetics profile, safety parameters and efficacy of 5-FU and Oxaliplatin.
Conclusion: Lactoferrin nanoparticles demonstrated an attractive drug delivery module to manage the colon adenocarcinoma as it has improved the antiproliferative activity of 5-FU and Oxaliplatin against colon adenocarcinoma cells. Moreover, it also improves the pharmacokinetic profile and safety parameters of the same drug in wistar rat.

Nanoparticles (NPs) have emerged as a potent choice for various applications, from drug delivery to agricultural studies, serving as an alternative and promising methodology for future advancements. They have been widely explored in delivery systems, demonstrating immense promise and high efficiency for the delivery of numerous biomolecules such as proteins and anticancer agents, either solely or modified with other compounds to enhance their capabilities. In addition, the utilization of NPs extends to antimicrobial studies, where they are used to develop novel antibacterial, antifungal, and antiviral formulations with advanced characteristics.

The dynamic equilibrium between acetylation and deacetylation is vital for cellular homeostasis. Parkinson's disease (PD), a neurodegenerative disorder marked by α-synuclein (α-syn) accumulation and dopaminergic neuron loss in the substantia nigra, is associated with a disruption of this balance. Therefore, correcting this imbalance with histone deacetylase (HDAC) inhibitors represents a promising treatment strategy for PD.

Parkinson's disease confronts challenges in drug delivery due to the blood-brain barrier. Intranasal delivery bypasses the blood-brain barrier for improved drug bioavailability, yet narrow nasal space and brief retention time hinder clinical applicability. We conducted a Bromocriptine Mesylate-loaded PLGA nanoparticles co-modified with low molecular weight protamine (LMWP) and lactoferrin (Lf) (LMWP/Lf-BCM-NPs) for nose-to-brain delivery.

Background: Biocompatible nanocarriers are widely employed as drug-delivery vehicles for treatment. Nevertheless, indiscriminate drug release, insufficient organ-specific targeting, and systemic toxicity hamper nanocarrier effectiveness. Stimuli-responsive nano-sized drug delivery systems (DDS) are an important strategy for enhancing drug delivery efficiency and reducing unexpected drug release.
