Modulation Of Antibacterial Activity And Cytotoxicity In Amphipathic Cyclic Peptide [R4w4] Using Histidine Substitution, Ryan Stueber

Pharmaceutical Sciences (MS) Theses

Antibiotics have been the gold standard frontline defense against bacterial infections for decades. At the same time, these infecting bacteria have continued to evolve to resist developed antibiotics in an almost endless cycle. As such, we aim to take an alternative approach utilizing antimicrobial peptides (AMPs) as a means to end this cycle. [R4W4] is among known AMPs that demonstrated antimicrobial activity against methicillin-resistant staphylococcus aureus (MRSA) with a minimum inhibitory concentration (MIC) of 2.67 μg/mL. This peptide had notably effective antimicrobial activity, especially relative to linear (R4W4). However, it displayed a concerning level of cytotoxicity; eliciting a human embryonic …

This Working Paper describes the public sector contribution to that process by tracing funding from the National Institutes of Health (NIH) related to published research on each of the 356 new drugs approved by the U.S. Food and Drug Administration from 2010-2019 as well as research on their 218 biological targets.

Assessment Of Evolutionary Relationships For Prioritization Of Myxobacteria For Natural Product Discovery, Andrew Ahearne, Hanan Albataineh, Scot E. Dowd, D. Cole Stevens

Faculty and Student Publications

Discoveries of novel myxobacteria have started to unveil the potentially vast phylogenetic diversity within the family Myxococcaceae and have brought about an updated approach to myxobacterial classification. While traditional approaches focused on morphology, 16S gene sequences, and biochemistry, modern methods including comparative genomics have provided a more thorough assessment of myxobacterial taxonomy. Herein, we utilize long-read genome sequencing for two myxobacteria previously classified as Archangium primigenium and Chondrococcus macrosporus, as well as four environmental myxobacteria newly isolated for this study. Average nucleotide identity and digital DNA–DNA hybridization scores from comparative genomics suggest previously classified as A. primigenium to instead be …

Mandatory Social Distancing For Covid-19 Outbreak And Its Economic Consequences In West Sumatera - Indonesia, Endrizal Ridwan, Besti Novianda

Jurnal Ekonomi Kesehatan Indonesia

The Governor of West Sumatra Province of Indonesia imposed a mandatory social distancing (PSBB) to slow down the Covid-19 outbreak from 22 April to 7 June 2020. The cons argued that PSBB was ineffective because of the impossibility to limit people’s movements. The pros, on the other hand, viewed PSBB as a training facility to increase people’s awareness about the pandemic. Our research aims at evaluating the effectiveness of PSBB by using the Kermack-McKendrick SIR pandemic model and the NLSUR non-linear least square estimation. Using daily data published by the Covid-19 task force, we found that PSBB had a positive …

Agricultural and Environmental Sciences Faculty Research

In the 21st century, we have witnessed three coronavirus outbreaks: SARS in 2003, MERS in 2012, and the ongoing pandemic coronavirus disease 2019 (COVID-19). The search for efficient vaccines and development and repurposing of therapeutic drugs are the major approaches in the COVID-19 pandemic research area. There are concerns about the evolution of mutant strains (e.g., VUI – 202012/01, a mutant coronavirus in the United Kingdom), which can potentially reduce the impact of the current vaccine and therapeutic drug development trials. One promising approach to counter the mutant strains is the “development of effective broad-spectrum antiviral drugs” against coronaviruses. This …

The Antibiogram: Key Considerations For Its Development And Utilization, William R. Truong, Levita Hidayat, Michael A. Bolaris, Lee Nguyen, Jason Yamaki

Pharmacy Faculty Articles and Research

The antibiogram is an essential resource for institutions to track changes in antimicrobial resistance and to guide empirical antimicrobial therapy. In this Viewpoint, data and examples from literature are presented that suggest institutions have not completely adopted the standardized approach in developing antibiograms, as variations in the development methodologies of antibiograms exist despite consensus guidelines (M39) published by CLSI. We emphasize developing antibiograms in line with the M39 recommendations will help ensure that they are accurate, reliable and valid, and highlight that understanding the limitations of antibiogram data is critical to ensuring appropriate interpretation and application to clinical decision-making. We …

Fanconi Syndrome Leading To Hypophosphatemic Osteomalacia Related To Tenofovir Use., Mana Rao, Liam Dadey, Thomas Glowa, Peter Veldkamp

Parkview Pharmacy Department

Tenofovir disoproxil fumarate (TDF) is used worldwide to treat and prevent Human Immunodeficiency Virus (HIV) infection. Fanconi syndrome is a complication of TDF use and is characterized by inadequate reabsorption of glucose, phosphate and protein in the proximal tubule of the kidney which may eventually lead to osteomalacia manifested by symptoms of pain, muscular weakness and difficulty ambulating. We present a patient with severe osteomalacia due to progressive and unrecognized Fanconi's syndrome, who responded rapidly to TDF withdrawal, oral phosphate repletion and calcitriol. With the widespread use of TDF-containing antiviral regimens, it is critically important that physicians adhere to screening …

Brief Overview Of Approaches And Challenges In New Antibiotic Development: A Focus On Drug Repurposing, Natalie K. Boyd, Chengwen Teng Pharm.D., Ph.D., Christopher R. Frei

Faculty Publications

Drug repurposing, or identifying new uses for existing drugs, has emerged as an alternative to traditional drug discovery processes involving de novo synthesis. Drugs that are currently approved or under development for non-antibiotic indications may possess antibiotic properties, and therefore may have repurposing potential, either alone or in combination with an antibiotic. They might also serve as “antibiotic adjuvants” to enhance the activity of certain antibiotics.

Characterization Of Di-Aryl Urea Compounds Against Acute And Chronic Toxoplasma Gondii, Austin Sanford

Theses & Dissertations

Toxoplasma gondii is an obligate intracellular parasite that has infected nearly 60 million individuals in the United States alone. Acute infection causes ill effects to the fetus in utero when mothers are primarily infected, and to immunocompromised individuals. Chronic infection consists of quiescent tissue cysts located primarily in brain tissue and is capable of reverting back to the acute stage causing severe toxoplasma encephalitis in immunocompromised individuals. Current treatments for acute infection are lacking while there are no approved treatments for the clearance of chronic infection. The aim of this research was to evaluate a family of di-aryl urea compounds …

Faculty and Student Publications

8-Aminoquinolines (8-AQs) are an important class of anti-infective therapeutics. The monoamine oxidases (MAOs) play a key role in metabolism of 8-AQs. A major role for MAO-A in metabolism of primaquine (PQ), the prototypical 8-AQ antimalarial, has been demonstrated. These investigations were further extended to characterize the enantioselective interactions of PQ and NPC1161 (8-[(4-amino-1-methylbutyl) amino]-5-[3, 4-dichlorophenoxy]-6-methoxy-4-methylquinoline) with human MAO-A and-B. NPC1161B, the (R)-(−) enantiomer with outstanding potential for malaria radical cure, treatment of visceral leishmaniasis and pneumocystis pneumonia infections is poised for clinical development. PQ showed moderate inhibition of human MAO-A and-B. Racemic PQ and (R)-(−)-PQ both showed marginally greater (1.2-and …
