Identification Of Human Kinin-Forming Enzyme Inhibitors From Medicinal Herbs, Hassan Madkhali, Amer Tarawneh, Zulfiqar Ali, Hoang V. Le

Faculty and Student Publications

The goal of this study was to assess the pharmacological effects of black tea (Camellia sinensis var. assamica) water extract on human kinin-forming enzymes in vitro. Tea is a highly consumed beverage in the world. Factor XII (FXII, Hageman factor)-independent-and-dependent activation of prekallikrein to kallikrein leads to the liberation of bradykinin (BK) from high-molecular-weight kininogen (HK). The excessive BK production causes vascular endothelial and nonvascular smooth muscle cell permeability, leading to angioedema. The prevalence of angiotensin-converting enzyme inhibitor (ACEI)-induced angioedema appears to be through BK. Both histamine and BK are potent inflammatory mediators. However, the treatments for histamine-mediated angioedema are …

Structure–Activity Relationships Of The Antimalarial Agent Artemisinin 10. Synthesis And Antimalarial Activity Of Enantiomers Of Rac-5Β-Hydroxy-D-Secoartemisinin And Analogs: Implications Regarding The Mechanism Of Action, Mohamed Jahan, Francisco Leon, Frank R. Fronczek, Khaled M. Elokely

Faculty and Student Publications

An efficient synthesis of rac-6-desmethyl-5β–hydroxy-D-secoartemisinin 2, a tricyclic analog of R-(+)-artemisinin 1, was accomplished and the racemate was resolved into the (+)-2b and (−)-2a enantiomers via their Mosher Ester diastereomers. Antimalarial activity resided with only the artemisinin-like enantiomer R-(−)-2a. Several new compounds 9–16, 19a, 19b, 22 and 29 were synthesized from rac-2 but the C-5 secondary hydroxyl group was surprisingly unreactive. For example, the formation of carbamates and Mitsunobu reactions were unsuccessful. In order to assess the unusual reactivity of 2, a single crystal X-ray crystallographic analysis revealed a close intramolecular hydrogen bond from the C-5 alcohol to the oxepane …

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 …

Transcriptomic Changes And The Roles Of Cannabinoid Receptors And Pparγin Developmental Toxicities Following Exposure To Δ9-Tetrahydrocannabinol And Cannabidiol, Zacharias Pandelides, Neelakanteswar Aluru, Cammi Thornton, Haley E. Watts

Faculty and Student Publications

Human consumption of cannabinoid-containing products during early life or pregnancy is rising. However, information about the molecular mechanisms involved in early life stage Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) toxicities is critically lacking. Here, larval zebrafish (Danio rerio) were used to measure THC- and CBD-mediated changes on transcriptome and the roles of cannabinoid receptors (Cnr) 1 and 2 and peroxisome proliferator activator receptor γ(PPARγ) in developmental toxicities. Transcriptomic profiling of 96-h postfertilization (hpf) cnr+/+ embryos exposed (6 - 96 hpf) to 4 μM THC or 0.5 μM CBD showed differential expression of 904 and 1095 genes for THC and CBD, respectively, …

Rage Differentially Altered In Vitro Responses In Vascular Smooth Muscle Cells And Adventitial Fibroblasts In Diabetes-Induced Vascular Calcification, Amber M. Kennon, James A. Stewart

Faculty and Student Publications

The Advanced Glycation End-Products (AGE)/Receptor for AGEs (RAGE) signaling pathway exacerbates diabetes-mediated vascular calcification (VC) in vascular smooth muscle cells (VSMCs). Other cell types are involved in VC, such as adventitial fibroblasts (AFBs). We hope to elucidate some of the mechanisms responsible for differential signaling in diabetes-mediated VC with this work. This work utilizes RAGE knockout animals and in vitro calcification to measure calcification and protein responses. Our calcification data revealed that VSMCs calcification was AGE/RAGE dependent, yet AFBs calcification was not an AGE-mediated RAGE response. Protein expression data showed VSMCs lost their phenotype marker, α-smooth muscle actin, and had …

Rap1a Regulates Cardiac Fibroblast Contraction Of 3d Diabetic Collagen Matrices By Increased Activation Of The Age/Rage Cascade, Stephanie D. Burr, James A. Stewart

Faculty and Student Publications

Cardiovascular disease is a common diabetic complication that can arise when cardiac fibroblasts transition into myofibroblasts. Myofibroblast transition can be induced by advanced glycated end products (AGEs) present in the extracellular matrix (ECM) activating RAGE (receptor for advanced glycated end products) to elicit intracellular signaling. The levels of AGEs are higher under diabetic conditions due to the hyperglycemic conditions present in diabetics. AGE/RAGE signaling has been shown to alter protein expression and ROS production in cardiac fibroblasts, resulting in changes in cellular function, such as migration and contraction. Recently, a small GTPase, Rap1a, has been identified to overlap the AGE/RAGE …

Faculty and Student Publications

COVID-19 was declared an international public health emergency in January, and a pandemic in March of 2020. There are over 125 million confirmed COVID-19 cases that have caused over 27 million deaths worldwide as of March 2021. COVID-19 is caused by the SARS-CoV-2 virus. SARS-CoV-2 presents a surface “spike” protein that binds to the ACE2 receptor to infect host cells. In addition to the respiratory tract, SARS-Cov-2 can also infect cells of the oral mucosa, which also express the ACE2 receptor. The spike and ACE2 proteins are highly glycosylated with sialic acid modifications that direct viral-host interactions and infection. Maackia …

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 …

Hiv-1 Tat Protein Promotes Neuroendocrine Dysfunction Concurrent With The Potentiation Of Oxycodone’S Psychomotor Effects In Female Mice, Mohammed F. Salahuddin, Fakhri Mahdi, Suresh P. Sulochana, Jason J. Paris

Faculty and Student Publications

Human immunodeficiency virus (HIV) is associated with neuroendocrine dysfunction which may contribute to co-morbid stress-sensitive disorders. The hypothalamic-pituitary-adrenal (HPA) or-gonadal (HPG) axes are perturbed in up to 50% of HIV patients. The mechanisms are not known, but we have found the HIV-1 trans-activator of transcription (Tat) protein to recapitulate the clinical phenotype in male mice. We hypothesized that HPA and/or HPG dysregulation contrib-utes to Tat-mediated interactions with oxycodone, an opioid often prescribed to HIV patients, in females. Female mice that conditionally-expressed the Tat1–86 protein [Tat(+) mice] or their counter-parts that did not [Tat(−) control mice] were exposed to forced swim …

The second purpose was to analyze how pharmacists across the United States viewed …

Emotion Regulation Among Adults With Asthma: Links With Short-Acting Inhaler Medication Overuse And Utilization Of Acute Medical Care, Victoria A. Green

Honors Theses

Effective control of asthma symptoms requires daily self-management activities, including use of short-acting or “rescue” inhaled medications. Overuse of short-acting inhaled medications, such as albuterol, can have negative side-effects, including respiratory infections and worse asthma symptom control. Existing research suggests that emotion plays an important role in airway inflammation and asthma symptom control. The objective of this study was to determine whether difficulties regulating emotion was associated with overuse of short-acting inhaled medications and acute medical care usage in adults with asthma. The sample included 401 adults with asthma recruited from an online panel of adults with chronic respiratory disease. …

The Role Of Cannabinoid Receptor 2 In Zebrafish Toxicities Following Developmental Exposure To Thc Or Cbd, Haley Watts

Honors Theses

As the laws concerning the regulation of Cannabis Sativa change across the globe, maternal use of cannabinoid-containing products during pregnancy is a greater concern than ever before. Little research has been conducted on the consequences of maternal use and developmental exposure to ∆9-tetrahydrocannabinol (THC) and cannabidiol (CBD. In this study, larval zebrafish (Danio rerio) were used to measure CBD and THC-mediated adverse outcomes including effects on larval length, eye area, and behavior in the cnr^+/+ and cnr2^-/- zebrafish strains where we discovered that cannabinoid exposure results in a decrease in each of these endpoints. Adult …

Beam Dynamics Corrections To The Run-1 Measurement Of The Muon Anomalous Magnetic Moment At Fermilab, T. Albahri, A. Anastasi, K. Badgley, S. Baeßler

Faculty and Student Publications

This paper presents the beam dynamics systematic corrections and their uncertainties for the Run-1 dataset of the Fermilab Muon g-2 Experiment. Two corrections to the measured muon precession frequency ωam are associated with well-known effects owing to the use of electrostatic quadrupole (ESQ) vertical focusing in the storage ring. An average vertically oriented motional magnetic field is felt by relativistic muons passing transversely through the radial electric field components created by the ESQ system. The correction depends on the stored momentum distribution and the tunes of the ring, which has relatively weak vertical focusing. Vertical betatron motions imply that the …
