N-n-Alkylation of nicotine converts nicotine from an agonist into an antagonist specifically for neuronal nicotinic acetylcholine receptor subtypes mediating nicotine-evoked dopamine release. Conformationally restricted analogs exhibit both high affinity and selectivity at this site, and are able to access the brain due to their ability to act as substrates for the blood-brain barrier choline transporter.

A Dexamethasone Prodrug Reduces The Renal Macrophage Response And Provides Enhanced Resolution Of Established Murine Lupus Nephritis, Fang Yuan, Dana Tabor, Richard K. Nelson, Hongjiang Yuan, Yijia Zhang, Jenny Nuxoll, Kimberly K. Bynote, Subodh M. Lele, Dong Wang, Karen A. Gould

Journal Articles: Pharmaceutical Sciences

We evaluated the ability of a macromolecular prodrug of dexamethasone (P-Dex) to treat lupus nephritis in (NZB × NZW)F1 mice. We also explored the mechanism underlying the anti-inflammatory effects of this prodrug. P-Dex eliminated albuminuria in most (NZB × NZW)F1 mice. Furthermore, P-Dex reduced the incidence of severe nephritis and extended lifespan in these mice. P-Dex treatment also prevented the development of lupus-associated hypertension and vasculitis. Although P-Dex did not reduce serum levels of anti-dsDNA antibodies or glomerular immune complexes, P-Dex reduced macrophage recruitment to the kidney and attenuated tubulointerstitial injury. In contrast to what was observed with free dexamethasone, …

Pharmacological Characterization Of A Novel Non-At1, Non-At2 Angiotensin Binding Site Identified As Neurolysin, Jamala D. Swindle, Kira L. Santos, Robert C. Speth

HPD Articles

The discovery of a novel non-AT1, non-AT2 binding site for angiotensins in the rodent brain and testis that is unmasked by the organomercurial compound para-chloromercuribenzoic acid (PCMB) has catalyzed efforts to purify and characterize this protein. We recently reported that this protein is neurolysin and now report upon the specificity of this binding site for various neuropeptides. Competition binding assays in rat brain and testis used (125)I-Sar(1), Ile(8) angiotensin II (Ang II) as the radioligand in the presence of saturating concentrations of AT1 and AT2 receptor antagonists and 100 μM parachloromercuribenzoate. Primary screening of 36 peptides and other compounds at …

Drug Firms, The Codification Of Diagnostic Categories, And Bias In Clinical Guidelines, Lisa Cosgrove, Emily E. Wheeler

Counseling, School Psychology & Sport Faculty Publication Series

The profession of medicine is predicated upon an ethical mandate: first do no harm. However, critics charge that the medical profession’s culture and its public health mission are being undermined by the pharmaceutical industry’s wide-ranging influence. In this article, we analyze how drug firms influence psychiatric taxonomy and treatment guidelines such that these resources may serve commercial rather than public health interests. Moving beyond a conflict-of-interest model, we use the conceptual and normative framework of institutional corruption to examine how organized psychiatry’s dependence on drug firms has distorted science. We suggest that academic-industry relationships have led to the corruption of …

Controlling The Size And Shape Of Polypeptide Colloidal Particles: Temperature Dependence Of Particle Formation, John P. Gavin, Nolan B. Holland, Kiril A. Streletzky

Undergraduate Research Posters 2013

A promising approach for developing new drug delivery vehicles is by using stimuli responsive hydrogel nanoparticles. Polypeptide surfactants designed in our lab have been shown to form micellar particles of varying sizes and shapes depending on the solution salt concentration. These responsive polypeptide surfactants consist of a small charged protein domain (foldon) with three elastin-like polypeptide (ELP) chains forming a three-armed star polymer. The size and shape of the micelles they form is dependent on the ratio of total ELP volume to head group area. By introducing linear ELP into the ELP-foldon solution, the total volume of ELP in the …

Pharmaceutical Science and Research

Obesity increases human cancer risk and the risk for cancer recurrence. Adipocytes secrete paracrine factors termed adipokines that stimulate signaling in cancer cells that induce proliferation. The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor that plays roles in tumorigenesis, is regulated by exogenous lipophilic chemicals, and has been explored as a therapeutic target for cancer therapy. Whether exogenous AHR ligands modulate adipokine stimulated breast cancer cell proliferation has not been investigated. We provide evidence that adipocytes secrete insulin-like growth factor 2 (IGF-2) at levels that stimulate the proliferation of human estrogen receptor (ER) positive breast cancer cells. Using …

Assessment Of The Drug-Drug Interaction Potential Of Anionic Components In The Diet And Herbal Medicines On Organic Anion Transporters (Slc22 Family), Li Wang

Theses and Dissertations

Numerous natural products are widely used as first-line/alternative therapeutics and dietary supplements in both western and eastern society. However, the safety and efficacy profiles for herbal products are still limited. Organic anion transporters (OATs; SLC22 family) are expressed in many barrier organs and mediate in vivo body disposition of a broad array of endogenous substances and clinically important drugs. As some dietary flavonoids and phenolic acids were previously demonstrated to interact with OATs, it is necessary to explore the potential interaction of such components found in natural products in order to avoid potential OAT-mediated drug-drug interactions (DDIs). The inhibitory effects …

We evaluated The American Psychiatric Association's Practice Guideline for the Treatment of Patients with Major Depressive Disorder to determine the existence of financial and intellectual conflicts of interest and examine their possible effects. We selected this guideline because of its influence on clinical practice and because this guideline recommends pharmacotherapy for all levels of depression, despite controversies over the evidence base.

Methods and Findings: We determined the number and type of financial conflicts of interest for members of the guideline development group as …

Development Of Hif-1Α/Hif-1Β Heterodimerization Inhibitors Using A Novel Bioluminescence Reporter Assay System For In Vitro High Throughput Screening And In Vivo Imaging, Yun-Chen Chiang

Dissertations and Theses (Open Access)

Tumor growth often outpaces its vascularization, leading to development of a hypoxic tumor microenvironment. In response, an intracellular hypoxia survival pathway is initiated by heterodimerization of hypoxia-inducible factor (HIF)-1α and HIF-1β, which subsequently upregulates the expression of several hypoxia-inducible genes, promotes cell survival and stimulates angiogenesis in the oxygen-deprived environment. Hypoxic tumor regions are often associated with resistance to various classes of radio- or chemotherapeutic agents. Therefore, development of HIF-1α/β heterodimerization inhibitors may provide a novel approach to anti-cancer therapy. To this end, a novel approach for imaging HIF-1α/β heterodimerization in vitro and in vivo was developed in this study …

Polysaccharide-Based Nanocarriers For Improved Drug Delivery, Nan Zhang

Dissertations - ALL

The field of drug delivery has provided a solution to the limited efficacy and high toxicity of many drugs. Nano-sized drug carriers are popular because their size allows for selective accumulation in the diseased area. Polysaccharides are non-toxic and biodegradable natural polymers that can serve as the basis for these nano-sized carriers. Polysialic acid (PSA) is such a polysaccharide with strong hydrophilicity that may reduce uptake by the reticuloendothelial system and prolong drug circulation. In this study, we developed PSA-based nanocarriers, specifically micelles and nanoparticles, for improved drug delivery with improved efficacy and minimized toxicity. PSA-based micelle systems were developed …
