Characterization Of Novel Cannabinoid Receptor 2-Selective Agonists At The Biochemical And Cellular Levels: Leads For Therapeutic Agents, Ashley M. Hine
Honors Scholar Theses
Putative cannabinoid receptor 2 (CB2)-selective agonists were identified from a library of commercially available compounds via inhibition of cAMP accumulation in high throughput screening. Binding affinity and receptor subtype selectivity were assessed using heterologous competition binding assays against the known cannabinoid orthosteric ligand CP55940. Test compounds ASX0152383 and CSC003141 preferentially bound to CB2, with no detection of binding to CB1 up to 1 mM. CMB038865 exhibited nearly 100-fold selectivity for CB1 over CB2, while CZ000026 bound non-preferentially to both receptors in the low micromolar range. To determine the extent of G protein coupling, GTPγS ...

Building on our earlier work of attaching a chemosensitizer (reversal agent) to a known drug pharmacophore, we have now expanded the structure-activity relationship study to include simplified versions of the chemosensitizer. The change from two aromatic rings in this head group to a single ring does not appear to detrimentally affect the antimalarial activity of the compounds. Data from in vitro heme binding and beta-hematin inhibition assays suggest that the single aromatic RCQ compounds retain activities against Plasmodium falciparum similar to those of CQ, although other mechanisms of action may be relevant to their activities.

The mosquito-transmitted dengue virus (DENV) infects millions of people in tropical and subtropical regions. Maturation of DENV particles requires proper cleavage of the viral polyprotein, including processing of 8 of the 13 substrate cleavage sites by dengue virus NS2B/NS3 protease. With no available direct-acting antiviral targeting DENV, NS2/NS3 protease is a promising target for inhibitor design. Current design efforts focus on the nonprime side of the DENV protease active site, resulting in highly hydrophilic and nonspecific scaffolds. However, the prime side also significantly modulates DENV protease binding affinity, as revealed by engineering the binding loop of aprotinin, a ...

Pharmacy Faculty Articles and Research
More than 6,800 rare diseases and conditions have been identified in the US, which affect 25–30 million Americans. In 1983, the US Congress enacted the Orphan Drug Act (ODA) to encourage the development and marketing of drugs to treat rare diseases and conditions. This study analyzed all orphan designations and FDA approvals since 1983 through 2015, discussed the effectiveness of incentives for the development of treatments for rare diseases, and reflected on the ethical imperatives for timely access to orphan drugs.
Study data were derived from the Food and Drug Administration (FDA) Orange Book and the ...
Target Based Design And Synthesis Of Fused Pyrimidines In The Potential Treatment Of Cancer And Opportunistic Infection, Khushbu Shah
Electronic Theses and Dissertations
This dissertation describes an introduction, background and research progress in the areas of agents designed as (a) selective Pneumocystis jirovecii dihydrofolate reductase (pjDHFR) inhibitors for pneumocystis pneumonia (PCP) infection; (b) inhibitors of microtubule polymerization and multiple receptor tyrosine kinase (RTK) for potential treatment of cancer; and (c) substrates for tumor-targeted therapy for cancer.
PCP is a host species-specific infection. Most of the drugs, synthesized and evaluated so far, have been tested against Pneumocystis carinii dihydrofolate reductase (the causative organism in rats), which would not necessarily be effective against pjDHFR (the causative organism in humans). Trimethoprim-sulfamethoxazole (TMP-SMX) combination, which has been ...
Preclinical Evaluation Of Ag10 For Therapeutic Use Against Familial Amyloid Cardiomyopathy And Its Application In Various Other Technologies, Mark Russell Miller
University of the Pacific Theses and Dissertations
Transthyretin (TTR) amyloidosis is a progressive, fatal disease in which deposition of amyloid derived from either mutant or wild-type TTR causes severe organ damage and dysfunction. TTR cardiomyopathy is an infiltrative, restrictive cardiomyopathy characterized by progressive left and right heart failure. Familial amyloid cardiomyopathy (FAC) is driven by pathogenic point mutations in the TTR gene that destabilize the TTR tetramer, prompting its dissociation into dimers and monomers, with subsequent misfolding, aggregation and deposition of toxic TTR amyloid aggregates in the myocardium. The most prevalent mutation that causes FAC is the V122I variant, carried by 3.4% of African Americans, that ...

Although membrane proteins represent most therapeutically relevant drug targets, the availability of atomic resolution structures for this class of proteins has been limited. Structural characterization has been hampered by the biophysical nature of these polytopic transporters, receptors, and channels, and recent innovations to in vitro techniques aim to mitigate these challenges. One such class of membrane proteins, the ATP-binding cassette (ABC) superfamily, are broadly expressed throughout the human body, required for normal physiology and disease-causing when mutated, yet lacks sufficient structural representation in the Protein Data Bank. However, recent improvements to biophysical techniques (e.g., cryo-electron microscopy) have allowed for ...

Skin cancer is extremely common, and melanoma causes about 80% of skin cancer deaths. In fact, melanoma kills over 50 thousand people around the world each year, and these numbers are rising. Clearly, standard treatments are not effectively treating melanoma, and alternative therapies are needed to address this problem. Hibiscus tea has been noted to have medicinal properties, including anticancer effects. Extracts from Hibiscus have been shown to inhibit the growth of a variety of cancer cells. In particular, recent studies found that polyphenols extracted from Hibiscus sabdariffa by organic solvents can inhibit melanoma cell growth. However, effects of aqueous ...
A Diversity-Oriented Synthesis Approach To Functionalized Azaheterocycles Using Cyclic Alpha-Halo Eneformamides, 2017 Central Washington University
A Diversity-Oriented Synthesis Approach To Functionalized Azaheterocycles Using Cyclic Alpha-Halo Eneformamides, Spencer A. Langevin
All Master's Theses
Functionalized piperidines, azepanes, azamacrocycles, morpholines, and thiomorpholines are common structural motifs found in a wide range of pharmaceuticals such as carmegliptine, levofloxacin, thioridazine, claviciptic acid, and azithomycin. As a result, there is a strong desire to construct highly functionalized nitrogen-bearing ring scaffolds in order to construct a wide range of drug possibilities. There are several non-modular and step-uneconomical synthetic methods used in the construction of these aforementioned motifs such as ring closing metathesis, ring expansions, and intramolecular reductive amination. In this research, we present a step-economical, cost-effective, scalable, and diversity-oriented synthesis approach to highly functionalized N-heterocycles through the intermediacy of ...

All Master's Theses
The synthesis and evaluation of structure-activity relationships of saturated nitrogen heterocycles is the focal point of various pharmaceutical companies thanks to the high biological activity of previously isolated azacycles. Here, we describe an operationally simple and highly efficient approach to macrocyclic lactams bearing vicinal stereocenters and a challenging cycloalkyne motif. The outcomes are achieved through a novel [4 + 2] cycloaddition reaction between an N-iodoarylated-1,3-azadiene and cyclic anhydrides, followed by interception of the cycloadducts in cross-coupling manifolds (e.g., Sonogashira coupling) and concomitant lithiation-cyclization of the tethered alkyne. An unprecedented example of a hydroamino alkylation that is transition metal-free ...

Design, Synthesis, And Evaluation Of Aryl Hydantoins And Ureas As Antischistosomal Agents, Chunkai Wang
Theses & Dissertations
Schistosomiasis is a tropical parasitic disease caused by infections with flukes of the genus Schistosoma, affecting as many as 440 million individuals worldwide, with 779 million living at risk of infection. A new drug for schistosomiasis is urgently needed as praziquantel (PZQ) is currently the drug of last resort and the development of resistance cannot be ignored, particularly in view of its large-scale use in many endemic countries. Furthermore, PZQ is active against adult but not juvenile schistosomes; this may be an important factor in the frequently observed treatment ‘failures’ in areas endemic for schistosomiasis.
The introduction of PZQ in ...

Down syndrome (DS; trisomy 21) is the most common survivable disorder due to aneuploidy. Individuals with DS may experience multiple comorbid health problems including congenital heart defects, endocrine abnormalities, skin and dental problems, seizure disorders, leukemia, dementia, and obesity. These associated conditions may necessitate pharmacotherapeutic management with various drugs. The complex pathobiology of DS may alter drug disposition and drug response in some individuals. For example, reports have documented increased rates of adverse drug reactions in patients with DS treated for leukemia and dementia. Intellectual disability resulting from DS may impact adherence to medication regimens. In this review, we highlight ...
Adoption Of Perioperative Lidocaine Infusion For The Reduction Of Postoperative Pain, 2016 University of Southern Mississippi
Adoption Of Perioperative Lidocaine Infusion For The Reduction Of Postoperative Pain, Brandon Scott Figueiredo
Laparoscopic capability provides numerous benefits to patients requiring abdominal surgical procedures. However, the use of these techniques has presented the anesthesia provider with a unique set of challenges in terms of perioperative management and postoperative pain reduction. No standardized method has existed to reduce postoperative pain and improve recovery following these procedures. There were three primary goals of this project. The first goal was to conduct a meta-analysis of randomized controlled trials to determine the benefit of the use of intravenous lidocaine infusions to reduce postoperative pain in laparoscopic abdominal surgery. Twelve articles were included in the meta-analysis that pertained ...
