Design, Synthesis, And Biological Screening Of Selective Mu Opioid Receptor Ligands As Potential Treatments For Opioid Addiction, Samuel Obeng
Theses and Dissertations
Today, more Americans die each year because of drug overdoses than are killed in motor vehicle accidents. In fact, in 2015, more than 33,000 individuals died due to an overdose of heroin or prescription opioids. Sadly, 40-60 % of patients on current opioid addiction treatment medications relapse. Studies have shown that the addiction/abuse liability of opioids are abolished in mu opioid receptor (MOR) knock-out mice; this indicates that the addiction and abuse liability of opioids are mainly mediated through MOR. Utilizing the “message-address concept”, the our laboratory reported a novel non-peptide, reversible MOR selective ligand 17-cyclopropylmethyl-3,14β-dihydroxy-4,5α-epoxy-6α (isoquinoline-3-carboxamido)morphinan (NAQ). Molecular modeling …
Altered Axon Initial Segment Structure And Function In Inflammatory Disease, Kareem C. Clark
Altered Axon Initial Segment Structure And Function In Inflammatory Disease, Kareem C. Clark
Theses and Dissertations
Axonal pathology is a key contributor to long-term disability in multiple sclerosis (MS), an inflammatory demyelinating disease of the central nervous system (CNS), but the mechanisms that underlie axonal insults remain unclear. While most axonal pathologies characterized in MS are a direct consequence of myelin loss, we propose that axonal pathologies also occur independent of demyelination. In support of this idea, we recently reported that mice that develop experimental autoimmune encephalomyelitis (EAE), a model commonly used to mimic the pathogenesis of MS, exhibit a structural and functional disruption of the axon initial segment (AIS), a subdomain of the axon that …
