Musah Department of Chemistry, State University of New York at Albany, 1400 Washington Ave, Albany, NY, 12222, USA ARTICLE INFO ABSTRACT Keywords: Plants that produce atropine and scopolamine fall under several genera within the nightshade family. Both Hierarchical classification atropine and scopolamine are used clinically, but they are also important in a forensics context because they are Psychoactive plants abused recreationally for their psychoactive properties. The accurate species attribution of these plants, which Seed species identifiction are related taxonomically, and which all contain the same characteristic biomarkers, is a challenging problem in Metabolome profiling both forensics and horticulture, as the plants are not only mind-altering, but are also important in landscaping as Direct analysis in real time-mass spectrometry ornamentals. Ambient ionization mass spectrometry in combination with a hierarchical classification workflow Chemometrics is shown to enable species identification of these plants. The hierarchical classification simplifies the classifi- cation problem to primarily consider the subset of models that account for the hierarchy taxonomy, instead of having it be based on discrimination between species using a single flat classification model. Accordingly, the seeds of 24 nightshade plant species spanning 5 genera (i.e. Atropa, Brugmansia, Datura, Hyocyamus and Mandragora), were analyzed by direct analysis in real time-high resolution mass spectrometry (DART-HRMS) with minimal sample preparation required.

  • Pharmacology – Inhalant Anesthetics
    Pharmacology- Inhalant Anesthetics Lyon Lee DVM PhD DACVA Introduction • Maintenance of general anesthesia is primarily carried out using inhalation anesthetics, although intravenous anesthetics may be used for short procedures. • Inhalation anesthetics provide quicker changes of anesthetic depth than injectable anesthetics, and reversal of central nervous depression is more readily achieved, explaining for its popularity in prolonged anesthesia (less risk of overdosing, less accumulation and quicker recovery) (see table 1) Table 1. Comparison of inhalant and injectable anesthetics Inhalant Technique Injectable Technique Expensive Equipment Cheap (needles, syringes) Patent Airway and high O2 Not necessarily Better control of anesthetic depth Once given, suffer the consequences Ease of elimination (ventilation) Only through metabolism & Excretion Pollution No • Commonly administered inhalant anesthetics include volatile liquids such as isoflurane, halothane, sevoflurane and desflurane, and inorganic gas, nitrous oxide (N2O). Except N2O, these volatile anesthetics are chemically ‘halogenated hydrocarbons’ and all are closely related. • Physical characteristics of volatile anesthetics govern their clinical effects and practicality associated with their use.

    PSYCHEDELIC DRUGS (p.l) 1. Terminology “hallucinogens” – induce hallucinations, although sensory distortions are more common “psychotomimetics” – to minic psychotic states, although truly most drugs in this class do not do so “phantasticums”or “psychedelics” – alter sensory perception (Julien uses “psychedelics”) alterations in perception, cognition, and mood, in presence of otherwise clear ability to sense” may increase sensory awareness, increase clarity, decrease control over what is sensed/experienced “self-A” may feel a passive observer of what “self-B” is experiencing often accompanied by a sense of profound meaningfulness, of divine or cosmic importance (limbic system?) these drugs can be classified by what NT they mimic: anti-ACh, agonists for NE, 5HT, or glutamate (See p. 332, Table 12.l in Julien, 9th Ed.) 2. The Anti-ACh Psychedelics e.g. scopolamine (classified as an ACh blocker) high affinity, no efficacy plant product: Belladonna or “deadly nightshade” (Atropa belladonna) Datura stramonium (jimson weed, stinkweed) Mandragora officinarum (mandrake plant) pupillary dilation (2nd to atropine) PSYCHEDELIC DRUGS (p.2) 2. Anti-ACh Psychedelics (cont.) pharmacological effects: e.g. scopolamine (Donnatal) clinically used to tx motion sickness, relax smooth muscles (gastric cramping), mild sedation/anesthetic effect PNS effects --- dry mouth relaxation of smooth muscles decreased sweating increased body temperature blurred vision dry skin pupillary dilation tachycardia, increased BP CNS effects --- drowsiness, mild euphoria profound amnesia fatigue decreased attention, focus delirium, mental confusion decreased REM sleep no increase in sensory awareness as dose increases --- restlessness, excitement, hallucinations, euphoria, disorientation at toxic dose levels --- “psychotic delirium”, confusion, stupor, coma, respiratory depression so drug is really an intoxicant, amnestic, and deliriant 3.

  • Zebrafish Behavioural Profiling Identifies GABA and Serotonin
    ARTICLE https://doi.org/10.1038/s41467-019-11936-w OPEN Zebrafish behavioural profiling identifies GABA and serotonin receptor ligands related to sedation and paradoxical excitation Matthew N. McCarroll1,11, Leo Gendelev1,11, Reid Kinser1, Jack Taylor 1, Giancarlo Bruni 2,3, Douglas Myers-Turnbull 1, Cole Helsell1, Amanda Carbajal4, Capria Rinaldi1, Hye Jin Kang5, Jung Ho Gong6, Jason K. Sello6, Susumu Tomita7, Randall T. Peterson2,10, Michael J. Keiser 1,8 & David Kokel1,9 1234567890():,; Anesthetics are generally associated with sedation, but some anesthetics can also increase brain and motor activity—a phenomenon known as paradoxical excitation. Previous studies have identified GABAA receptors as the primary targets of most anesthetic drugs, but how these compounds produce paradoxical excitation is poorly understood. To identify and understand such compounds, we applied a behavior-based drug profiling approach. Here, we show that a subset of central nervous system depressants cause paradoxical excitation in zebrafish. Using this behavior as a readout, we screened thousands of compounds and identified dozens of hits that caused paradoxical excitation. Many hit compounds modulated human GABAA receptors, while others appeared to modulate different neuronal targets, including the human serotonin-6 receptor. Ligands at these receptors generally decreased neuronal activity, but paradoxically increased activity in the caudal hindbrain. Together, these studies identify ligands, targets, and neurons affecting sedation and paradoxical excitation in vivo in zebrafish. 1 Institute for Neurodegenerative Diseases, University of California, San Francisco, CA 94143, USA. 2 Cardiovascular Research Center and Division of Cardiology, Department of Medicine, Massachusetts General Hospital, Harvard Medical School, Charlestown, MA 02129, USA.
