Toward A Robust Computational Screening Strategy For Identifying Glycosaminoglycan Sequences That Display High Specificity For Target Proteins, Nehru Viji Sankaranarayanan, Umesh R. Desai

Medicinal Chemistry Publications

Glycosaminoglycans (GAGs) interact with many proteins to regulate processes such as hemostasis, cell adhesion, growth and differentiation and viral infection. Yet, majority of these interactions remain poorly understood at a molecular level. A major reason for this state is the phenomenal structural diversity of GAGs, which has precluded analysis of specificity of their interactions. We had earlier presented a computational protocol for predicting “high-specificity” GAG sequences based on combinatorial virtual library screening (CVLS) technology. In this work, we expand the robustness of this technology through rigorous studies of parameters affecting GAG recognition of proteins, especially antithrombin and thrombin. The CVLS …

Crystal Structures Of Influenza A Virus Matrix Protein M1: Variations On A Theme, Martin K. Safo, Faik N. Musayev, Philip D. Mosier, Qibing Zhou, Hang Xie, Umesh R. Desai

Medicinal Chemistry Publications

Matrix protein 1 (M1) of the influenza A virus plays multiple roles in virion assembly and infection. Interest in the pH dependence of M1's multiple functions led us to study the effect of subtle pH changes on M1 structure, resulting in the elucidation of a unique low-pH crystal structure of the N1-165-domain of A/WSN/33 (H1N1) M1 that has never been reported. Although the 2.2 Å crystal structure of M1 N-terminus shows a dimer with the two monomers interacting in a face-to-face fashion at low pH as observed earlier, a 44° rotation of the second monomer has led to a significantly …

Phenoxybenzamine Is Neuroprotective In A Rat Model Of Severe Traumatic Brain Injury, Thomas Rau, Aakriti Kothiwal, Annela Rova, Joseph F. Rhoderick, David J. Poulsen

Biomedical and Pharmaceutical Sciences Faculty Publications

Phenoxybenzamine (PBZ) is an FDA approved α-1 adrenergic receptor antagonist that is currently used to treat symptoms of pheochromocytoma. However, it has not been studied as a neuroprotective agent for traumatic brain injury (TBI). While screening neuroprotective candidates, we found that phenoxybenzamine reduced neuronal death in rat hippocampal slice cultures following exposure to oxygen glucose deprivation (OGD). Using this system, we found that phenoxybenzamine reduced neuronal death over a broad dose range (0.1 μM–1 mM) and provided efficacy when delivered up to 16 h post-OGD. We further tested phenoxybenzamine in the rat lateral fluid percussion model of TBI. When administered …

Atypical Signaling And Functional Desensitization Response Of Mas Receptor To Peptide Ligands, Kalyan C. Tirupula, Russell Desnoyer, Robert C. Speth, Sadashiva S. Karnik

HPD Articles

MAS is a G protein-coupled receptor (GPCR) implicated in multiple physiological processes. Several physiological peptide ligands such as angiotensin-(1-7), angiotensin fragments and neuropeptide FF (NPFF) are reported to act on MAS. Studies of conventional G protein signaling and receptor desensitization upon stimulation of MAS with the peptide ligands are limited so far. Therefore, we systematically analyzed G protein signals activated by the peptide ligands. MAS-selective non-peptide ligands that were previously shown to activate G proteins were used as controls for comparison on a common cell based assay platform. Activation of MAS by the non-peptide agonist (1) increased intracellular calcium and …

Dietary Supplement Labeling: Cognitive Biases, Market Manipulation & Consumer Choice, Michael Mccann

Law Faculty Scholarship

There exists increasing concern that the Dietary Supplements Health and Education Act (DSHEA) has proven ineffective. Much of the concern regards the disparity in legislative treatment between dietary supplements, foods, and pharmaceutical drugs. Namely, while pharmaceutical drugs must undergo years of costly pre-market testing, most supplements, like foods, can immediately enter the market, and only after repeated instances of adverse reactions can the Food and Drug Administration (FDA) remove them. Such a framework appears to belie both consumer expectations and marketing strategies, as supplements tend to be most perceived for their apparent medicinal qualities. This philosophy of waiting for a …

Nudging The Fda, W. Nicholson Price Ii, I. Glenn Cohen

Law Faculty Scholarship

[Excerpt] "The FDA’s regulation of drugs is frequently the subject of policy debate, with arguments falling into two camps. On the one hand, a libertarian view of patients and the health care system holds high the value of consumer choice. Patients should get all the information and the drugs they want; the FDA should do what it can to enforce some basic standards but should otherwise get out of the way. On the other hand, a paternalist view values the FDA’s role as an expert agency standing between patients and a set of potentially dangerous drugs and potentially unscrupulous or …

Making Do In Making Drugs: Innovation Policy And Pharmaceutical Manufacturing, W. Nicholson Price Ii

Law Faculty Scholarship

Despite increasing recalls, contamination events, and shortages, drug companies continue to rely on outdated manufacturing plants and processes. Drug manufacturing’s inefficiency and lack of innovation stand in stark contrast to drug discovery, which is the focus of a calibrated innovation policy that combines patents and FDA regulation. Pharmaceutical manufacturing lags far behind the innovative techniques found in other industries due to high regulatory barriers and ineffective intellectual property incentives. Among other challenges, although manufacturers tend to rely on trade secrecy because of the difficulty in enforcing patents on manufacturing processes, trade secrecy provides limited incentives for innovation. To increase those …

Intuitive, But Not Simple: Including Explicit Water Molecules In Protein-Protein Docking Simulations Improves Model Quality, Hardik I. Parikh, Glen E. Kellogg

Medicinal Chemistry Publications

Characterizing the nature of interaction between proteins that have not been experimentally co-crystallized requires a computational docking approach that can successfully predict the spatial conformation adopted in the complex. In this work, the Hydropathic INTeractions (HINT) force field model was used for scoring docked models in a data set of 30 high-resolution crystallographically characterized “dry” protein-protein complexes, and was shown to reliably identify native-like models. However, most current protein-protein docking algorithms fail to explicitly account for water molecules involved in bridging interactions that mediate and stabilize the association of the protein partners, so we used HINT to illuminate the physical …

Chromatin Structure In Situ: The Contribution Of Dna Ultrastructural Cytochemistry, Massimo Derenzini, Ada L. Olins, Donald E. Olins

Pharmaceutical Sciences Faculty Publications

Ultrastructural studies conducted in situ using conventional transmission electron microscopy have had relatively little impact on defining the structural organization of chromatin. This is due to the fact that in routine transmission electron microscopy, together with the deoxyribonucleoprotein, many different intermingled substances are contrasted, masking the ultrastructure of chromatin. By selective staining of DNA in thin sections, using the Feulgen-like osmium-ammine reaction, these drawbacks have been overcome and worthwhile data have been obtained both on the gross morphology and the ultrastructural-functional organization of chromatin in situ. In the present study these results are reviewed and discussed in light of recent …

Correlation Of Treatment Dose Enoxaparin With Anti-Xa Concentrations In Adult Hemodialysis Inpatients, Paul E. Brumley, Miroslav A. Anguelov, Jason P. Hecht, Dane L. Shiltz

Scholarship and Professional Work – COPHS

Enoxaparin, a low-molecular-weight-heparin, is being used in hemodialysis patients despite a lack of guideline or manufacturer dose recommendations. Due to enoxaparin’s renal excretion, the possibility of accumulating anti-Xa concentrations in hemodialysis patients using enoxaparin creates a hemorrhagic risk, calling for more research. The objectives of this study are to determine the correlation between treatment dose enoxaparin use and anti-Xa concentrations within the defined therapeutic range in patients receiving chronic, scheduled hemodialysis to determine the degree of change in anti-Xa concentrations in those cases where a concentration was obtained before and after a specific hemodialysis session, and to determine if there …

A Retrospective Comparison Of Daptomycin Thrice-Weekly Versus Q48h Dosing In Hemodialysis Patients With Vancomycin-Resistant Enterococcus (Vre) Or Methicillin-Resistant Staphylococcus Aureus (Mrsa) Bacteremia, Katie L. Axford, Dane L. Shiltz

Scholarship and Professional Work – COPHS

Background. Multi-drug resistant bacteria are a growing concern in healthcare. Daptomycin is being used with increasing frequency in the treatment of vancomycin-resistant enterococci (VRE) and methicillin-resistant Staphylococcus aureus (MRSA) bacteremias in hemodialysis (HD) patients. Thrice-weekly dosing of daptomycin in this population would allow for coordination of dosing with common outpatient HD schedules. The aim of this study is to determine if thrice-weekly dosing of daptomycin is equivalent to dosing every 48 hours in patients receiving chronic intermittent hemodialysis. Equivalence will be assessed with regard to microbiological cure, clinical cure, hospital length of stay, and mortality. Methods. All patients with positive …

Cinacalcet Administration By Gastrostomy Tube In A Child Receiving Peritoneal Dialysis, Kristen R. Nichols, Chad A. Knoderer, Bethanne Johnston, Amy C. Wilson

Scholarship and Professional Work – COPHS

A 2-year-old male with chronic kidney disease with secondary hyperparathyroidism developed hypercalcemia while receiving calcitriol, without achieving a serum parathyroid hormone concentration within the goal range. Cinacalcet 15 mg (1.2 mg/kg), crushed and administered via gastrostomy tube, was added to the patient’s therapy. This therapy was effective in achieving targeted laboratory parameters in our patient despite instructions in the prescribing information that cinacalcet should always be taken whole.

Waveguide Evanescent Field Scattering Microscopy: Bacterial Biofilms And Their Sterilization Response Via Uv Irradiation, Qamrun Nahar, Frederik Fleiβner, Jeremiah Shuster, Michael Morawitz, Christopher Halfpap, Mihaela Stefan, Uwe Langbein, Gordon Southam, Silvia Mittler

Physiology and Pharmacology Publications

Waveguide Evanescent Field Scattering (WEFS) microscopy is introduced as a new and simple tool for label-free, high contrast imaging of bacteria and bacteria sensors. Bacterial microcolonies and single bacteria were discriminated both by their bright field images and by their evanescent scattering intensity. By comparing bright field images with WEFS images, the proportion of planktonic: sessile (i.e., ‘floating’: attached) bacteria were measured. Bacteria were irradiated with UV light, which limited their biofilm forming capability. A quantitative decrease in attachment of individual, sessile bacteria and in attached, microcolony occupied areas was easily determined within the apparent biofilms with increasing UV dose. …
