RESEARCH: UNIVERSITY OF MARYLAND, BALTIMORE Research Topic : Novel Cholinergics for Treatment of CNS Disorders Major depression is a widespread psychiatric disorder demonstrating severe symptoms in how a person feels, thinks, and handles daily activities (nih.gov). Furthermore, it is linked to diminished quality of life, medical morbidity, and mortality. Depression has a lifetime prevalence of 16% in the United States and appears to be caused by a combination of genetic, biological, environmental, and psychological factors. Current antidepression medications possess significant problems, including a delayed onset of action and different therapeutic effects in differing patients. As such, rapid acting fully efficacious antidepressants are urgently needed. Non- selective muscarinic antagonists have been shown to display antidepressant effects, but this is accompanied by undesired cognitive deficits. The hypothesis of this project is that antagonism of one or more muscarinic subtypes leads to an antidepressant effect, and antagonism at others lead to the cognitive deficits. As selective agonists and antagonists are not available for the 5 muscarinic receptor subtypes, we aim to design and synthesize-- using the scaffolds of L-670548, L-687306, WAY-132983, and L-689660 as model scaffolds-- muscarinic ligands to allow a delineation of the structure activity relationship (SAR) for both selectivity and efficacy, with the ultimate goal of a muscarinic antagonist lacking cognitive deficits. JOHNS HOPKINS UNIVERSITY (Graduate Research Assistant): • Constructed two total syntheses with optimization of all reactions to obtain novel β-methyl carbapenem antibiotics and various derivatives thereof. • Purified each novel compound via column chromatography or preparative HPLC Ran biological assays using these compounds and purified ThnQ/SarQ grown from bacterial cells over-expressing these proteins. • Constructed synthetic standards to compare the compounds produced from the above assays (2009-2013). UNIVERSITY OF VIRGINIA (Undergraduate Research Assistant): • Designed and successfully synthesized various derivatives of FTY720 (2008-2009) Abstract Title of Dissertation: Novel Cholinergics for Treatment of Central Nervous System Disorders Chad R. Johnson, Ph.D., 2019 Dissertation Directed by: Dr. Andrew Coop, Professor and Associate Dean for Academic Affairs, Pharmaceutical Sciences, School of Pharmacy, University of Maryland, Baltimore Approximately 16% of Americans are diagnosed with major depressive disorder, a mental disorder thought be caused by a combination of characterized by genetic, biological, environmental, and psychological factors. It can be accompanied by low self-esteem, loss of interest in normally enjoyable activities, low energy, and diminished quality of life. Between 2- 7% of adults with this disorder die by suicide. In addition, almost half of patients who are treated initially with an SSRI do not achieve complete remission, and nearly a third after four different treatment regimens (nimh.nih.gov). While counseling and antidepressant medication can be effective treatments, current selective serotonin re-uptake inhibitors (SSRI's) take weeks before therapeutic effects are observed. This "delay" period of action is not well understood and presents a significant challenge for medical

CellSensor ® NFAT-bla Jurkat cells (Cat. no. K1671) contain a beta-lactamase (bla ) reporter gene under control of the Nuclear Factor of Activated T-cells (NFAT) response element. M1-NFAT-bla Jurkat cells are functionally validated for Z’-factor and EC 50 concentrations of carbachol (Figure 1). In addition, GeneBLAzer ® M1-NFAT-bla CHO-K1 cells have been tested for assay performance under variable conditions. Target Description Muscarinic acetylcholine receptors are members of the G protein-coupled receptor (GPCR) superfamily. Muscarinic receptors are widely distributed and mediate the actions of acetylcholine in both the CNS and peripheral tissues. Five muscarinic receptor subtypes have been identified and are referred to as M 1-M5 (1-5). The five genes that encode the muscarinic receptors all belong to the rhodopsin-line family (Family A) and share strong sequence homology but have unique regions located at the amino terminus (extracellular) and in the third intracellular loop. The M 1, M3, and M 5 receptor subtypes couple through the G q/11 class of G-proteins and activate the phopholipase C pathway. Activation of this pathway in turn leads to increases in free intracellular calcium levels as inositol triphosphate mediates release of calcium from the endoplasmic reticulum.

  • Muscarinic Acetylcholine Receptor
    mAChR Muscarinic acetylcholine receptor mAChRs (muscarinic acetylcholine receptors) are acetylcholine receptors that form G protein-receptor complexes in the cell membranes of certainneurons and other cells. They play several roles, including acting as the main end-receptor stimulated by acetylcholine released from postganglionic fibersin the parasympathetic nervous system. mAChRs are named as such because they are more sensitive to muscarine than to nicotine. Their counterparts are nicotinic acetylcholine receptors (nAChRs), receptor ion channels that are also important in the autonomic nervous system. Many drugs and other substances (for example pilocarpineand scopolamine) manipulate these two distinct receptors by acting as selective agonists or antagonists. Acetylcholine (ACh) is a neurotransmitter found extensively in the brain and the autonomic ganglia. www.MedChemExpress.com 1 mAChR Inhibitors & Modulators (+)-Cevimeline hydrochloride hemihydrate (-)-Cevimeline hydrochloride hemihydrate Cat.

  • Muscarinic Toxin 7 Signals Via Ca2+/Calmodulin-Dependent Protein Kinase Kinase Β to Augment Mitochondrial Function and Prevent Neurodegeneration
    Molecular Neurobiology (2020) 57:2521–2538 https://doi.org/10.1007/s12035-020-01900-x Muscarinic Toxin 7 Signals Via Ca2+/Calmodulin-Dependent Protein Kinase Kinase β to Augment Mitochondrial Function and Prevent Neurodegeneration Ali Saleh1 & Mohammad Golam Sabbir1 & Mohamad-Reza Aghanoori1,2 & Darrell R. Smith1 & Subir K. Roy Chowdhury1 & Lori Tessler1 & Jennifer Brown1 & Eva Gedarevich3 & Markos Z. Kassahun3 & Katie Frizzi3 & Nigel A. Calcutt 3 & Paul Fernyhough1,2 Received: 9 January 2020 /Accepted: 9 March 2020 /Published online: 20 March 2020 # The Author(s) 2020 Abstract Mitochondrial dysfunction is implicated in a variety of neurodegenerative diseases of the nervous system. Peroxisome proliferator–activated receptor-γ coactivator-1α (PGC-1α) is a regulator of mitochondrial function in multiple cell types. In sensory neurons, AMP-activated protein kinase (AMPK) augments PGC-1α activity and this pathway is depressed in diabetes leading to mitochondrial dysfunction and neurodegeneration. Antimuscarinic drugs targeting the muscarinic acetylcholine type 1 receptor (M1R) prevent/reverse neurodegeneration by inducing nerve regeneration in rodent models of diabetes and chemotherapy-induced peripheral neuropathy (CIPN). Ca2+/calmodulin-dependent protein kinase kinase β (CaMKKβ)isan upstream regulator of AMPK activity. We hypothesized that antimuscarinic drugs modulate CaMKKβ to enhance activity of AMPK, and PGC-1α, increase mitochondrial function and thus protect from neurodegeneration. We used the specific M1R antagonist muscarinic toxin 7 (MT7) to manipulate muscarinic signaling in the dorsal root ganglia (DRG) neurons of normal rats or rats with streptozotocin-induced diabetes. DRG neurons treated with MT7 (100 nM) or a selective muscarinic antagonist, pirenzepine (1 μM), for 24 h showed increased neurite outgrowth that was blocked by the CaMKK inhibitor STO-609 (1 μM) or short hairpin RNA to CaMKKβ.
