Structure-Activity Relationship Studies Of Synthetic Cathinones And Related Agents, Rachel A. Davies
Structure-Activity Relationship Studies Of Synthetic Cathinones And Related Agents, Rachel A. Davies
Theses and Dissertations
Synthetic cathinones and related agents represent an international drug abuse problem, and at the same time an important class of clinically useful compounds. Structure-activity relationship studies are needed to elucidate molecular features underlying the pharmacology of these agents. Illicit methcathinone (i.e., MCAT), the prototype of the synthetic cathinone class, exists as a racemic mixture. Though the differences in potency and target selectivity between the positional and optical isomers of synthetic cathinones and related agents have been demonstrated to have important implications for abuse and therapeutic potential, the two MCAT isomers have never been directly compared at their molecular targets: the …
Diuretic And Natriuretic Activity Of Faah Inhibition In The Renal Medulla: A Proposed Role Of Palmitoylethanolamide And Its Regulation By Renal Medullary Interstitial Cells, Sara Dempsey
Theses and Dissertations
Hypertension is a critical public health issue worldwide, and in the United States, it is the leading cause of heart disease, stroke, and kidney failure, contributing to more than 1,100 deaths per day. It is proposed that the renal medulla combats increased blood pressure by releasing a neutral lipid from the lipid droplets of medullary interstitial cells, termed medullipin, which induces diuresis- natriuresis and vasodepression. The renal medulla is enriched with fatty acid lipid ethanolamides including the endocannabinoid anandamide (AEA), palmitoylethanolamide (PEA), and oleoylethanolamide (OEA), along with their primary hydrolyzing enzyme fatty acid amide hydrolase (FAAH). Our lab is investigating …
Effects Of A Heroin Conjugate Vaccine On The Antinociceptive And Abuse-Related Effects Of Heroin In Rats And Monkeys, Kathryn L. Schwienteck
Effects Of A Heroin Conjugate Vaccine On The Antinociceptive And Abuse-Related Effects Of Heroin In Rats And Monkeys, Kathryn L. Schwienteck
Theses and Dissertations
The increase in heroin use is one factor contributing to the current opioid epidemic in the United States. There are three Food and Drug Administration (FDA) approved medications for the treatment of opioid use disorder (OUD), and these include agonist (i.e. methadone and buprenorphine) and antagonist (i.e. naltrexone) therapies. Although these medications are effective for some patients, regulatory constraints for agonist therapies limit access and patient compliance for naltrexone is poor. The development of new therapies, such as immunopharmacotherapies, for the treatment of OUD is a priority for the National Institute of Drug Abuse. A heroin immunopharmacotherapy, or vaccine, produces …
Molecular Targets Of Psychedelics And Their Role In Behavioral Models Of Hallucinogenic Action, Hiba Z. Vohra
Molecular Targets Of Psychedelics And Their Role In Behavioral Models Of Hallucinogenic Action, Hiba Z. Vohra
Theses and Dissertations
Psychedelics are a subset of hallucinogenic drugs that exert their characteristic effects through agonist activity at the serotonin receptor 2A (5-HT2A). In this study, I aimed to characterize the modulatory role of the metabotropic glutamate subtype 2 receptor (mGluR2) in the 5-HT2A-specific rodent model of hallucinogenic action, head-twitch response (HTR). Secondly, I aimed to explore if 5-HT2A agonist-induced deficits in prepulse inhibition (PPI) of the startle response, an additional model of hallucinogenic action, could be produced in mice. Though 5-HT2A agonist-induced PPI deficits, which represent interruptions in normal sensorimotor gating, have been described in …
The Analgesic-Like Properties Of Alcohol In Animal Models Of Chronic Pain, Bradley Neddenriep
The Analgesic-Like Properties Of Alcohol In Animal Models Of Chronic Pain, Bradley Neddenriep
Theses and Dissertations
Chronic pain and excessive alcohol consumption are individually problems in our society today. Alcohol Use Disorder (AUD) affects 15.1 million adult Americans each year. Chronic pain affects over 100 million people annually in the United States. However, there is growing evidence suggesting that these two conditions can often be interrelated with chronic pain increasing consumption of alcohol, and excessive alcohol consumption increasing pain that leaves a feedback cycle trapping millions of patients in an ever worsening spiral. Large population-based studies show an association between pain and alcohol abuse, suggesting a link between increased alcohol use and reduced pain. While rodent …
