Differential Effects of Alkaloids on Memory in Rodents
www.nature.com/scientificreports OPEN Diferential efects of alkaloids on memory in rodents Patrick M. Callahan1,2, Alvin V. Terry Jr.1,2, Manuel C. Peitsch3, Julia Hoeng3* & Kyoko Koshibu3* Nicotinic acetylcholine receptors (nAChRs) play a critical role in the neuropharmacology of learning and memory. As such, naturally occurring alkaloids that regulate nAChR activity have gained interest for understanding and potentially improving memory function. In this study, we tested the acute efects of three known nicotinic alkaloids, nicotine, cotinine, and anatabine, in suppressing scopolamine-induced memory defcit in rodents by using two classic memory paradigms, Y-maze and novel object recognition (NOR) in mice and rats, respectively. We found that all compounds were able to suppress scopolamine-induced spatial memory defcit in the Y-maze spontaneous alternation paradigm. However, only nicotine was able to suppress the short-term object memory defcit in NOR, despite the higher doses of cotinine and anatabine used to account for their potential diferences in nAChR activity. These results indicate that cotinine and anatabine can uniquely regulate short-term spatial memory, while nicotine seems to have more robust and general role in memory regulation in rodents. Thus, nAChR-activating alkaloids may possess distinct procognitive properties in rodents, depending on the memory types examined. Te cholinergic system of the brain is a critical regulator of attention, memory, and higher-order cognitive processing, and its defcits are central to the etiology of dementia1. As such, nicotinic acetylcholine receptors (nAChRs) have gained much interest as a target of drug development 2. Neuronal nAChRs are pentameric pro- teins composed of various combinations of α (α2–α9) and β (β2–β4) nAChR subunits, diferentially expressed throughout the nervous system. -

Prisinzano Date approved: July 18, 2012 ii ABSTRACT Kappa opioid (KOP) receptors have been suggested as an alternative target to the mu opioid (MOP) receptor for the treatment of pain because KOP activation is associated with fewer negative side-effects (respiratory depression, constipation, tolerance, and dependence). The KOP receptor has also been implicated in several abuse-related effects in the central nervous system (CNS). KOP ligands have been investigated as pharmacotherapies for drug abuse; KOP agonists have been shown to modulate dopamine concentrations in the CNS as well as attenuate the self-administration of cocaine in a variety of species, and KOP antagonists have potential in the treatment of relapse. One drawback of current opioid ligand investigation is that many compounds are based on the morphine scaffold and thus have similar properties, both positive and negative, to the parent molecule. Thus there is increasing need to discover new chemical scaffolds with opioid receptor activity. -

Evaluating the Real-World Effectiveness of Bupropion Versus Varenicline for Smoking Cessation: Exploring the Role of Nicotine Metabolism and Medication Adherence
Evaluating the Real-World Effectiveness of Bupropion Versus Varenicline for Smoking Cessation: Exploring the Role of Nicotine Metabolism and Medication Adherence By Jiahui Zhang A thesis submitted in conformity with the requirements for the degree of Master of Science Graduate Department of Pharmacology and Toxicology University of Toronto © Copyright by Jiahui Zhang (2017) Evaluating the Real-World Effectiveness of Bupropion Versus Varenicline for Smoking Cessation: Exploring the Role of Nicotine Metabolism and Medication Adherence Jiahui Zhang Degree of Master of Science Graduate Department of Pharmacology and Toxicology University of Toronto ABSTRACT Bupropion and varenicline are effective, first-line prescription-only pharmacotherapies for smoking cessation; however, their real-world use is limited by affordability and accessibility. Using a novel internet-based randomized design, we evaluated the real-world effectiveness of mailed bupropion and varenicline, as well as the roles of nicotine metabolism (NMR) and medication adherence, in a sample of interested smokers using web-based recruitment and follow up. Quit rates at end of treatment (EOT) were significantly higher for varenicline (30.2%) compared to bupropion (19.6%). Quit rates at 6 months (14.0%) and 12 months (12.1%) were not significantly different between bupropion and varenicline. Increased medication compliance significantly improved cessation outcomes at EOT. NMR was associated with nicotine dependence. Varenicline benefited Slow Metabolizers of nicotine whilst bupropion benefited Normal Metabolizers. Even though real-world quit rates were comparable to clinical trials, improving medication compliance and implementing personalized pharmacological and behavioral interventions are promising approaches to increase efficacy of smoking cessation pharmacotherapies. ii ACKNOWLEDGEMENTS First and foremost, I would like to express my sincerest appreciation to my supervisor, Dr. -

Are Supplements Supplemented? Evaluating the Composition of Complementary and Alternative Medicines Using Mass Spectrometry and Metabolomics
Are supplements supplemented? Evaluating the composition of complementary and alternative medicines using mass spectrometry and metabolomics By Elly Gwyn Crighton BForensics in Forensic Biology & Toxicology (First Class Honours) BSc in Molecular Biology & Biomedical Science This thesis is presented for the degree of Doctor of Philosophy Perth, Western Australia at Murdoch University 2020 Declaration I declare that: i. The thesis is my own account of my research, except where other sources are acknowledged. ii. The extent to which the work of others has been used is clearly stated in each chapter and certified by my supervisors. iii. The thesis contains as its main content, work that has not been previously submitted for a degree at any other university. i Abstract The complementary and alternative medicines (CAM) industry is worth over US$110 billion globally. Products are available to consumers with little medical advice; with many assuming that such products are ‘natural’ and therefore safe. However, with adulterated, contaminated and fraudulent products reported on overseas markets, consumers may be placing their health at risk. Previous studies into product content have reported undeclared plant materials, ingredient substitution, adulteration and contamination. However, no large-scale, independent audit of CAM has been undertaken to demonstrate these problems in Australia. This study aimed to investigate the content and quality of CAM products on the Australian market. 135 products were analysed using a combination of next-generation DNA sequencing and liquid chromatography-mass spectrometry. Nearly 50% of products tested had contamination issues, in terms of DNA, chemical composition or both. 5% of the samples contained undeclared pharmaceuticals. -

July 16, 2018 VIA ELECTRONIC SUBMISSION and HAND DELIVERY Division of Dockets Management Food and Drug Administration 5630 Fishe
Jose Luis Murillo Vice President Regulatory Affairs July 16, 2018 VIA ELECTRONIC SUBMISSION AND HAND DELIVERY Division of Dockets Management Food and Drug Administration 5630 Fishers Lane, Rm. 1061 Rockville, MD 20852 Re: Docket No. FDA-2017-N-6189 (83 Fed. Reg. 11,818, March 16, 2018) Advance Notice of Proposed Rulemaking on Tobacco Product Standard for Nicotine Level of Certain Tobacco Products Altria Client Services (“ALCS”), on behalf of Philip Morris USA Inc. (“PM USA”), John Middleton Company (“JMC”), and Sherman Group Holdings LLC and its subsidiaries (“Nat Sherman”),1 submits these comments to the Food and Drug Administration’s (“FDA’s” or the “Agency’s”) Advance Notice of Proposed Rulemaking (“ANPRM”) on a Tobacco Product Standard for Nicotine Level of Certain Tobacco Products. The ANPRM comes within the context of an industry in the midst of transformative change. Cigarette smoking is at historically low levels and continues to decline. At the same time, a new market is emerging in innovative noncombustible tobacco products that are potentially less harmful than cigarettes. There is now a scientific consensus that noncombustible products, like e-vapor, are substantially less risky than conventional cigarettes. It is smoke, and not nicotine, that causes most tobacco- related harm. And adult smokers are increasingly expressing interest in switching from cigarettes to less risky alternatives. We agree that a nicotine product standard of some sort may make sense in a future regulatory system, but this requires the pre-existence of a marketplace with alternative, FDA-authorized, reduced risk products; more information about the relative risks of those products; and a regulatory system that respects the rights of adults to make decisions based on accurate information.
