Nutlin-3a is an MDM2-p53 interaction antagonist that is under investigation in preclinical models for a variety of pediatric malignancies, including neuroblastoma, retinoblastoma, leukemia, and rhabdomyosarcoma. In the current research, we conducted preclinical pharmacology studies of nutlin-3a to evaluate the synergistic effect of the nutlin-3a and topotecan combination on neuroblastoma cell growth, to assess the effect of nutlin-3a on breast cancer resistance protein (BCRP), and to characterize the disposition of nutlin-3a in the mouse plasma and multiple tissues.
Activating the p53 pathway might offer a new therapy for neuroblastoma. In the first part of the study, we assessed the effect of …

Reactive Oxygen Species Modulation Of Na/K-Atpase Regulates Fibrosis And Renal Proximal Tubular Sodium Handling, Jiang Liu, David J. Kennedy, Yanling Yan, Joseph I. Shapiro Md
Pharmaceutical Science and Research
The Na/K-ATPase is the primary force regulating renal sodium handling and plays a key role in both ion homeostasis and blood pressure regulation. Recently, cardiotonic steroids (CTS)-mediated Na/K-ATPase signaling has been shown to regulate fibrosis, renal proximal tubule (RPT) sodium reabsorption, and experimental Dahl salt-sensitive hypertension in response to a high-salt diet. Reactive oxygen species (ROS) are an important modulator of nephron ion transport. As there is limited knowledge regarding the role of ROS-mediated fibrosis and RPT sodium reabsorption through the Na/K-ATPase, the focus of this review is to examine the possible role of ROS in the regulation of Na/K-ATPase …

Nanoparticulate Formulations Of Mithramycin Analogs For Enhanced Cytotoxicity, Daniel Scott, Jürgen Rohr, Younsoo Bae
Pharmaceutical Sciences Faculty Publications
Mithramycin (MTM), a natural product of soil bacteria from the Streptomyces genus, displays potent anticancer activity but has been limited clinically by severe side effects and toxicities. Engineering of the MTM biosynthetic pathway has produced the 3-side-chain-modified analogs MTM SK (SK) and MTM SDK (SDK), which have exhibited increased anticancer activity and improved therapeutic index. However, these analogs still suffer from low bioavailability, short plasma retention time, and low tumor accumulation. In an effort to aid with these shortcomings, two nanoparticulate formulations, poly(ethylene glycol)-poly(aspartate hydrazide) self-assembled and cross-linked micelles, were investigated with regard to the ability to load and pH …

Designing Allosteric Inhibitors Of Thrombin, Preetpal Sidhu
Theses and Dissertations
Thrombin is a key enzyme of the coagulation cascade exhibiting important roles in both pro-coagulation and anti-coagulation processes. Most clinically used anticoagulant drugs, including polymeric heparin, warfarin, hirudin, argatroban and the recently approved dabigatran, aim to reduce thrombin activity. There are several binding domains on thrombin including the active site, anion-binding exosites I and II, and the sodium binding site. We hypothesized that thrombin may be better regulated through an allosteric process mediated by small molecules binding to either exosite I or II. An appropriately designed allosteric regulator that reduces the procoagulant signal in a finely tuned manner may maintain …

Acetaminophen: Beyond Pain And Fever-Relieving, Eric R. Blough, Miaozong Wu
MIIR Faculty Research
Acetaminophen, also known as APAP or paracetamol, is one of the most widely used analgesics (pain reliever) and antipyretics (fever reducer). According to the U.S. Food and Drug Administration, currently there are 235 approved prescription and over-the-counter drug products containing acetaminophen as an active ingredient. When used as directed, acetaminophen is very safe and effective; however when taken in excess or ingested with alcohol hepatotoxicity and irreversible liver damage can arise. In addition to well known use pain relief and fever reduction, recent laboratory and pre-clinical studies have demonstrated that acetaminophen may also have beneficial effects on blood glucose levels, …

Interferons As Therapeutic Agents In Infectious Diseases, Mckenzie C. Ferguson, Scott Bergman, Cathy Santanello
Pharmacy Faculty Research, Scholarship, and Creative Activity
This article explains the rationale for development of interferons as therapeutic agents, and describes commercial products available today. It also provides a summary of studies that have been performed with interferons for use as exogenous biological response modifiers in viral infections. Overall, the best data exist for treatment of viral hepatitis B and C, for which interferons are a cornerstone of therapy. Although infections with human papillomavirus and common cold viruses sometimes respond favorably to interferons, their outcomes are far from ideal. Finally, the role of interferons as vaccine adjuvants is still being explored but could be promising.

Neuroprotective properties of bilobalide, a specific constituent of Ginkgo extracts, were tested in a mouse model of stroke. After 24 h of middle cerebral artery occlusion (MCAO), bilobalide reduced infarct areas in the core region (striatum) by 40–50% when given at 10 mg/kg 1 h prior to MCAO. Neuroprotection was also observed at lower doses, or when the drug was given 1 h past stroke induction. Sensorimotor function in mice was improved by bilobalide as shown by corner and chimney tests. When brain metabolism in situ was monitored by microdialysis, MCAO caused a rapid disappearance of extracellular glucose in the …

Work Placement Blogs To Harness Diverse Learning Experiences And Foster A Community Of Practice, Julie Dunne
Conference papers
Students on work placement will have very different experiences from each other, however they are generally not connected to their peers, but working with professionals under the guidance of a college tutor. Therefore during placement they are not formally supported by peers and cannot learn from the diverse range of activities their peers will experience. An active learning community and a sense of connectedness to others are critical to real learning (LaPointe, 2008), while learning through participation in a community of practice involves sharing experiences and discovering how to improve by regularly interacting with peers (Wenger, 2002). The aim of …

Cross-linked nanoassemblies (CNAs) with a degradable core were prepared for sustained release of 17-N-allylamino-17-demethoxygeldanamycin (17-AAG), a potent inhibitor of heat shock protein 90 (HSP90). The particle size of CNAs ranged between 100 and 250 nm, which changed depending on the cross-linking yields and drug entrapment method. CNAs with a 1% cross-linking yield entrapped 17-AAG in aqueous solutions, yet degraded in 3 hrs. CNAs entrapped 5.2 weight% of 17-AAG as the cross-linking yield increased to 10%, retaining more than 80% of particles for 24 hrs. CNAs with drugs entrapped after the cross-linking reactions were 100 nm and remained stable in both …
