A Drug's Life: The Untapped Potential Of Secondary Pharmacology Studies In Drug Development, Christina Scott

The University of New Hampshire Law Review

The United States Food and Drug Administration has evolved over the past century to regulate new medicine and protect the public from harmful or ineffective drugs. Drug development and testing science have advanced rapidly alongside the FDA’s increased regulation, enabling pharmaceutical companies to assess a drug's potential adverse reactions by studying its reactivity with various proteins called "off-target receptors." Off-target proteins are often screened and reported in the Investigational New Drug Application as a percentage indicating the drug's binding strength to each protein, which suggests the strength of a particular adverse drug effect. Adverse drug effects often lead to unfavorable …

Microbial Symbiont-Based Detoxification Of Different Phytotoxins And Synthetic Toxic Chemicals In Insect Pests And Pollinators, Olivia Kline, Neelendra K. Joshi

Entomology and Plant Pathology Faculty Publications and Presentations

Insects are the most diverse form of life, and as such, they interact closely with humans, impacting our health, economy, and agriculture. Beneficial insect species contribute to pollination, biological control of pests, decomposition, and nutrient cycling. Pest species can cause damage to agricultural crops and vector diseases to humans and livestock. Insects are often exposed to toxic xenobiotics in the environment, both naturally occurring toxins like plant secondary metabolites and synthetic chemicals like herbicides, fungicides, and insecticides. Because of this, insects have evolved several mechanisms of resistance to toxic xenobiotics, including sequestration, behavioral avoidance, and enzymatic degradation, and in many …

Pharmacogenomic Biomarkers Of Angiotensin Converting Enzyme Inhibitors (Aceis) Induced Cough Among Healthy Emiratis And Multi-Ethnic Hypertensive Patients, Sahar Mohammad Altoum

Theses

Pharmacogenomics (PGx) is an emerging field that merges genetics with pharmacology. It focuses on how an individual's genetic makeup influences their response to specific medications. This relatively new area of medicine seeks to understand the genetic factors that affect drug efficacy and safety. One practical application of PGx is in the context of treatment with angiotensin-converting enzyme inhibitors (ACEIs), which are widely used medications for managing hypertension. However, ACEIs are often associated with cough as a side effect, leading to drug discontinuation and the adoption of alternative medications like Angiotensin II receptor blockers (ARBs). The prevalence of ACEIs-induced cough varies …

The Multipurpose Dna Repair/Redox Protein Ape1 In Rodent And Human Lewy Body Disease, Kristin Marie Miner

Electronic Theses and Dissertations

Lewy body disorders are a family of neurodegenerative conditions characterized by proteostatic and redox disequilibrium, leading to deposition of the abundant protein α-synuclein in hallmark inclusions and oxidative damage to DNA. Sublethal oxidative DNA damage in neurons is repaired predominantly by the base excision repair pathway, which involves the coordinated activity of several enzymes, including apurinic/apyrimidinic endonuclease 1 (APE1). Despite emerging connections between α-synuclein, oxidative stress, and DNA damage/repair, along with evidence demonstrating the multifunctional nature of APE1, the link between APE1 and α-synuclein has not yet been explored.

Here, we conducted a broad investigation of APE1 in the context …

The Effect Of Novel Microtubule Modulators On Experimental Lewy Body Disease, Anuj S. Jamenis

Electronic Theses and Dissertations

In Lewy body disorders, α-synuclein aggregates are believed to destabilize the microtubular framework. However, microtubules are a challenging therapeutic target, as excessive rigidity or flexibility afforded by microtubule modulators may be neurotoxic. Thus, the objective of the present study was to evaluate dual-acting microtubule- stabilizing/destabilizing agents in cellular and animal models of early-stage Lewy body disease.

In Aim 1 we tested the dual-acting tricylic pyrimido[4,5-b]indole analogs AG161-47 and AG161-41 in an in vitro preformed fibril induced model of Lewy body disease. We found that both compounds reduced preformed fibril-seeded α-synucleinopathy without toxicity in primary hippocampal cultures. AG161-47 subtly impacted microtubule …
