In Vitro Metabolism Of The Synthetic Cannabinoids Px-1, Px-2, Px-3 And A Comparison Of Their Clearance Rates In Human Liver Microsomes, Travon Cooman

Graduate Theses, Dissertations, and Problem Reports

Detection of SCs in body fluids continue to be a challenge because of limited metabolism data, lack of standards and reference mass spectrometry data. In vivo and in vitro experiments help elucidate metabolite markers for novel psychoactive substances and can prompt synthesis of standards to verify proposed metabolites. In this study, metabolism of three SCs N-(1-amino-1-oxo-3-phenylpropan-2-yl)-1-(5-fluoropentyl)-1H-indole-3-carboxamine (PX-1), N-(1-amino-1-oxo-3-phenylpropan-2-yl)-1-(5-fluropentyl)-1H-indazole-3-carboxamide (PX-2), and N-(1-amino-1-oxo-3-phenylpropan-2-yl)-1-(cyclohexylmethyl)-1H-indazole-3-carboxamide (PX-3) were investigated using human liver microsomes. Previous studies showed PX-3 as the most potent CB1 and CB2 receptor agonist.

Half-life and clearance data were acquired using liquid chromatography- tandem mass spectrometry. Metabolite elucidation was performed using liquid chromatography …

Investigating The Effect Of Sodium Benzoate On Immune Cells And Microbial Populations In The Small Intestine Of Murine Species., Shelby Pedigo

Senior Honors Projects, 2010-2019

Dietary ingredients can influence the mucosal surface morphology and mucosal immunity of the gastrointestinal tract. Additional health concerns and behavioral changes have been attributed to the consumption of foods containing preservatives and additives. Sodium benzoate (SB) is a commonly used bacteriostatic in food and beverages. This study investigates the effects of SB on the gut bacteria and mucosal health in the gastrointestinal tract of laboratory mice. The extent of lymphocytic infiltration in intestinal villi and granular density of Paneth cells in the ileum were used as evaluators of mucosal immunity. Adult C57BL/6 mice were randomly assigned to two …
