The objective for this study was to describe consumer opinions regarding medication use, the health care system, and pharmacists to help identify new roles for pharmacists from the consumer perspective. Data were obtained from the 2015 and 2016 National Consumer Surveys on the Medication Experience and Pharmacist Roles. Out of the representative sample of 36,673 respondents living in the United States, 80% (29,426) submitted written comments at the end of the survey. Of these, …

Understanding The Impact Of Bcrp And Pgp Efflux Transporters On The Disposition Of Their Endogenous, Xenobiotic And Dietary Substrates, Samit Ganguly

Theses and Dissertations (ETD)

Breast Cancer Resistant Protein (BCRP) and P-glycoprotein (PGP) are membrane-bound efflux transporters that transport multiple chemical classes of compounds and act as barriers to tissue permeability, thereby regulating tissue exposure of their substrates. The role of these transporters in therapeutic resistance of their xenobiotic substrates due to their expression and efflux function at target organs/tissues, especially in brain and intestine, is well established, which has fueled investigation toward identification of their inhibitors. Multiple clinically used drugs and dietary chemicals have been reported to inhibit these transporters and potentially increase the exposure of concomitantly administered BCRP and/or PGP substrates, which might …

Aminoflavone Inhibits Α6-Integrin And Growth Of Tamoxifen Resistant Breast Cancer, Petreena S. Campbell

Loma Linda University Electronic Theses, Dissertations & Projects

Approximately 40% of estrogen receptor positive (ER+) breast cancer patients develop resistance to standard of care agent tamoxifen, while ER negative (ER-) breast cancer patients are intrinsically resistant to tamoxifen. Resistance often promotes metastasis, recurrence and death. Tumor-initiating cells (TICs) represent key contributors to resistance and adhesion protein α6-integrin is a putative TIC biomarker. Investigational agent Aminoflavone (AF) demonstrates efficacy against breast cancer cells irrespective of ER status. Interestingly, we found tamoxifen resistant (TamR) cells and tumors exhibited elevated α6-integrin expression in comparison to their tamoxifen sensitive counterparts. AF effectively disrupted mammospheres enriched for TICs and reduced α6-integrin levels in …

Hiv Integrase Inhibitor Pharmacogenetics And Clinical Outcomes: An Exploratory Association Study, Derek E. Murrell

Electronic Theses and Dissertations

As HIV is now primarily a chronic condition, treatment is given life-long with changes as necessitated by alterations in tolerability and efficacy. Thus, personalized medicine may be useful in the prevention of unnecessary drug exposure and avoidable side effects. Three of the four currently available HIV integrase strand transfer inhibitors (INSTIs), raltegravir, elvitegravir, and dolutegravir, are widely utilized antiretrovirals in the USA and exhibit variations in outcomes among subjects. To interrogate differences among subjects receiving these drugs, we investigated the association of several single nucleotide polymorphisms (SNPs) with drug exposure, clinical outcomes, and subject-reported adverse events. HIV+ adults (≥18 years …

A Clinically Relevant Mouse Model Of Cisplatin-Induced Kidney Injury., Cierra Nichole Sharp

Electronic Theses and Dissertations

Cisplatin is a potent chemotherapeutic used for the treatment of many solid cancers, including testicular, ovarian, and lung cancer. Cisplatin causes many adverse side effects, of which nephrotoxicity leading to acute kidney injury is dose-limiting. Approximately 30% of patients will develop nephrotoxicity with cisplatin, and will either have their next dose of cisplatin lowered, skipped, or be switched to a less nephrotoxic chemotherapeutic altogether. These outcomes are not ideal when trying to treat cancer. Previously, it was believed that patients could recover from cisplatin-induced acute kidney injury with little to no lasting effects, but recent longitudinal studies have shown this …

Dietary Inclusion Of Enriched Chicken Bone Broth Prevents Trigeminal Sensitization Meditated By Early Life Stress, Orion Peterson

MSU Graduate Theses

Early life stress is considered a risk factor for development of migraine, which is a prevalent painful neurological disorder involving sensitization and activation of trigeminal neurons, and irritable bowel syndrome, a condition often comorbid with chronic migraine. The focus of my study was to determine the effects of early life stress and dietary inclusion of enriched chicken bone broth on trigeminal nociceptor sensitization and the gut microbiota. Adult Sprague-Dawley male “sender” rats subjected to primary traumatic stress were placed next to breeding or pregnant female rats that served as “receiver” rats (secondary traumatic stress) and in proximity to the offspring …

Glutathione: A Small Molecule With Big Sense, Cristina E. Raya, Debasish Bandyopadhyay

Chemistry Faculty Publications and Presentations

Glutathione, a peptide found in microbes, plants and animals including human plays a key role in maintaining healthy cells. The peptide exists in both reduced and oxidized forms. Synthesis of GSH occurs in the cytosol of cells, and the extent of glutathione synthesis relies on various factors, such as amino acid availability, protein activity etc. Once synthesized, glutathione exists in both forms: oxidized (GSSG) and reduced (GSH). Oxidized glutathione characterized by its disulfide linkage. On the other hand, presence of a thiol group characterizes the reduced glutathione. This thiol makes the tripeptide an essential component of health; it makes glutathione …

“Do We Know Jack” About Jak? A Closer Look At Jak/Stat Signaling Pathway, Emira Bousoik, Hamidreza Montazeri Aliabadi

Pharmacy Faculty Articles and Research

Janus tyrosine kinase (JAK) family of proteins have been identified as crucial proteins in signal transduction initiated by a wide range of membrane receptors. Among the proteins in this family JAK2 has been associated with important downstream proteins, including signal transducers and activators of transcription (STATs), which in turn regulate the expression of a variety of proteins involved in induction or prevention of apoptosis. Therefore, the JAK/STAT signaling axis plays a major role in the proliferation and survival of different cancer cells, and may even be involved in resistance mechanisms against molecularly targeted drugs. Despite extensive research focused on the …

Limiting Antibiotic Use In Acute Sinusitis: Partly A Matter Of Vocabulary?, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

In his issue introduction, the editor-in-chief of Journal of Patient-Centered Research and Reviews comments on an included article that describes the successful use of an electronic medical record best practice alert to reduce the rate of antibiotic prescription for acute sinusitis. Various methods previously tried to improve antibiotic stewardship in this illness are briefly reviewed. Borrowing on the model of acute bronchitis, it is suggested that a change in conveyed diagnostic vocabulary to “sinus cold” when describing acute sinusitis may help limit antibiotics for this predominantly viral infection.

Evaluating Feasibility Of Blockchain Application For Dscsa Compliance, Tracie Scott, Armand L. Post, Johnny Quick, Sohail Rafiqi

SMU Data Science Review

Abstract. We evaluated the feasibility of using a blockchain technology to create a traceability solution for pharmaceutical drugs that would promote compliance with recent legislation. Counterfeit and other illegitimate pharmaceutical drugs threaten patient safety, drug efficacy, and patient trust. The purpose of the Drug Supply Chain Security Act (DSCSA) is to greatly reduce distribution of illegitimate drugs by requiring all pharmaceuticals to be serialized and traceable from the manufacturer through the supply chain to the dispenser. A software application to serialize and track pharmaceuticals must overcome numerous obstacles. In particular, the solution must provide a high degree of trust while …

We describe noncovalent, reversible asparagine ethylenediamine (AsnEDA) inhibitors of the Plasmodium falciparum proteasome (Pf20S) β5 subunit that spare all active subunits of human constitutive and immuno-proteasomes. The compounds are active against erythrocytic, sexual, and liver-stage parasites, against parasites resistant to current antimalarials, and against P. falciparum strains from patients in Africa. The β5 inhibitors synergize with a β2 inhibitor in vitro and in mice and with artemisinin. P. falciparum selected for resistance to an AsnEDA β5 inhibitor surprisingly harbored a point mutation in the noncatalytic β6 subunit. The β6 mutant was resistant to the species-selective Pf20S β5 inhibitor but remained …

A V-To-F Substitution In Sk2 Channels Causes Ca2+ Hypersensitivity And Improves Locomotion In A C. Elegans Als Model, Young-Woo Nam, Sabia N. Baskoylu, Dimitris Gazgalis, Razan Orfali, Meng Cui, Anne C. Hart, Miao Zhang

Pharmacy Faculty Articles and Research

Small-conductance Ca2+-activated K+ (SK) channels mediate medium afterhyperpolarization in the neurons and play a key role in the regulation of neuronal excitability. SK channels are potential drug targets for ataxia and Amyotrophic Lateral Sclerosis (ALS). SK channels are activated exclusively by the Ca2+-bound calmodulin. Previously, we identified an intrinsically disordered fragment that is essential for the mechanical coupling between Ca2+/calmodulin binding and channel opening. Here, we report that substitution of a valine to phenylalanine (V407F) in the intrinsically disordered fragment caused a ~6 fold increase in the Ca2+ sensitivity of SK2-a channels. This substitution resulted in a novel interaction between …

Salts Of Therapeutic Agents: Chemical, Physicochemical, And Biological Considerations, Deepak Gupta, Deepak Bhatia, Vivek S. Dave, Vijaykumar B. Sutariya, Sheeba Varghese Gupta

Pharmacy Faculty/Staff Publications

The physicochemical and biological properties of active pharmaceutical ingredients (APIs) are greatly affected by their salt forms. The choice of a particular salt formulation is based on numerous factors such as API chemistry, intended dosage form, pharmacokinetics, and pharmacodynamics. The appropriate salt can improve the overall therapeutic and pharmaceutical effects of an API. However, the incorrect salt form can have the opposite effect, and can be quite detrimental for overall drug development. This review summarizes several criteria for choosing the appropriate salt forms, along with the effects of salt forms on the pharmaceutical properties of APIs. In addition to a …

Effects Of G Protein Signalling Modulator 3 On Cellular Signalling, Aneta A. Surmanski

Electronic Thesis and Dissertation Repository

G protein coupled receptors (GPCRs) promote G protein heterotrimer (Gα·GDP/Gbg) activation.GPCRsignalling is limited via G protein GTPase activity and b-arrestin-receptor interactions. G Protein Signalling Modulators (GPSMs) are proteins that may influence receptor signalling through G protein activity. GPSM3 modulates their activity by binding to Ga_i-GDP, limiting nucleotide exchange and preventing its re-association to Gbg. The impact of GPSM3 on signalling is unknown.We hypothesize that GPSM3 will decrease Ga_i-dependent signalling while promoting Gbg-dependent signalling in G_i-coupled GPCRs.

GPSM3 significantly inhibited b-arrestin recruitment to α_2A-adrenergic and m-opioid receptors via a Gbg-dependent mechanism, …

Enzyme Replacement Therapies: What Is The Best Option?, Azam Safary, Mostafa Akbarzadeh Khiavi, Rahimeh Mousavi, Jaleh Barar, Mohammad Rafi

Department of Neurology Faculty Papers

Despite many beneficial outcomes of the conventional enzyme replacement therapy (ERT), several limitations such as the high-cost of the treatment and various inadvertent side effects including the occurrence of an immunological response against the infused enzyme and development of resistance to enzymes persist. These issues may limit the desired therapeutic outcomes of a majority of the lysosomal storage diseases (LSDs). Furthermore, the biodistribution of the recombinant enzymes into the target cells within the central nervous system (CNS), bone, cartilage, cornea, and heart still remain unresolved. All these shortcomings necessitate the development of more effective diagnosis and treatment modalities against LSDs. …

Cysteine Modifiers Suggest An Allosteric Inhibitory Site On The Cal Pdz Domain, Yu Zhao, Patrick R. Cushing, David C. Smithson, Maria Pellegrini, Alexandre A. Pletnev, Sahar Al-Ayyoubi, Andrew V. Grassetti, Scott A. Gerber, R. Kiplin Guy, Dean R. Madden

Pharmaceutical Sciences Faculty Publications

Protein–protein interactions have become attractive targets for both experimental and therapeutic interventions. The PSD-95/Dlg1/ZO-1 (PDZ) domain is found in a large family of eukaryotic scaffold proteins that plays important roles in intracellular trafficking and localization of many target proteins. Here, we seek inhibitors of the PDZ protein that facilitates post-endocytic degradation of the cystic fibrosis (CF) transmembrane conductance regulator (CFTR): the CFTR-associated ligand (CAL). We develop and validate biochemical screens and identify methyl-3,4-dephostatin (MD) and its analog ethyl-3,4-dephostatin (ED) as CAL PDZ inhibitors. Depending on conditions, MD can bind either covalently or non-covalently. Crystallographic and NMR data confirm that MD …

Thorson, Steven G. Van Lanen

Pharmaceutical Sciences Faculty Publications

Muraymycins are antibacterial natural products from Streptomyces spp. that inhibit translocase I (MraY), which is involved in cell wall biosynthesis. Structurally, muraymycins consist of a 5′-C-glycyluridine (GlyU) appended to a 5″-amino-5″-deoxyribose (ADR), forming a disaccharide core that is found in several peptidyl nucleoside inhibitors of MraY. For muraymycins, the GlyU-ADR disaccharide is further modified with an aminopropyl-linked peptide to generate the simplest structures, annotated as the muraymycin D series. Two enzymes encoded in the muraymycin biosynthetic gene cluster, Mur29 and Mur28, were functionally assigned in vitro as a Mg·ATP-dependent nucleotidyltransferase and a Mg·ATP-dependent phosphotransferase, respectively, both modifying the …
