Assessment of alkoxylphenacyl-based polycarbonates as a potential platform for controlled delivery of a model anti-glaucoma drug.

Treatment strategies for glaucoma will benefit from injectable and/or implantable delivery systems that can achieve sustained delivery of neuroprotective agents (to the posterior segment) and/or intraocular pressure lowering drugs (to the anterior…

Emerging lung cancer therapeutic targets based on the pathogenesis of bone metastases.

Lung cancer is the second most common cancer and the leading cause of cancer related mortality in both men and women. Each year, more people die of lung cancer than of colon, breast, and prostate cancers combined. It is widely accepted that tumor…

Osteoactivin (GPNMB) ectodomain protein promotes growth and invasive behavior of human lung cancer cells.

The potential application of GPNMB/OA as a therapeutic target for lung cancer will require a greater understanding of the impact of GPNMB/OA ectodomain (ECD) protein shedding into tumor tissues. Thus, in this work we characterized GPNMB/OA expression…

Gelucire-stabilized nanoparticles as a potential DNA delivery system.

Clinical viability of gene delivery systems has been greatly impacted by potential toxicity of the delivery systems. Recently, we reported the nanoparticle (NP) preparation process that employs biocompatible materials such as Gelucire(R) 44/14 and…

Antitumor efficacy and tolerability of systemically administered gallium acetylacetonate-loaded gelucire-stabilized nanoparticles.

The widespread clinical success with most gallium compounds in cancer therapy is markedly hampered by lack of tumor specific accumulation, poor tumor permeability and undesirable toxicity to healthy tissues. The aim of this work was to investigate…

Formulation and photoirradiation parameters that influenced photoresponsive drug delivery using alkoxylphenacyl-based polycarbonates.

Recently, we reported the synthesis and biocompatibility of alkoxylphenacyl-based polycarbonates (APP); a promising new class of polymers that undergo photo-induced chain scission. In the current study, nanoparticles (NPs) were prepared from the APP…

Biocompatibility, efficacy and biodistribution of Gelucire-stabilized nanoparticles engineered for docetaxel delivery.

Docetaxel is a potent anticancer agent that will benefit greatly from alternative delivery systems that can overcome several reported adverse effects due to the drug itself and/or the solvent system in the current clinical formulation. In this…

Effects of gelucire content on stability, macrophage interaction and blood circulation of nanoparticles engineered from nanoemulsions.

The main objective of the study is to investigate the efficacy of Gelucire 44/14 (gelucire) in facilitating formation of cetyl alcohol (CA)-based nanoparticle (NP) and to assess the effects on key NP properties and functions. NPs from oil-in-water…

Antitumor effect of novel gallium compounds and efficacy of nanoparticle-mediated gallium delivery in lung cancer.

The widespread application of gallium (Ga) in cancer therapy has been greatly hampered by lack of specificity resulting in poor tumor accumulation and retention. To address the challenge, two lipophilic gallium (III) compounds (gallium hexanedione;…
