The Stimulants and Hallucinogens Under Consideration: a Brief Overview of Their Chemistry and Pharmacology
Drug and Alcohol Dependence, 17 (1986) 107-118 107 Elsevier Scientific Publishers Ireland Ltd. THE STIMULANTS AND HALLUCINOGENS UNDER CONSIDERATION: A BRIEF OVERVIEW OF THEIR CHEMISTRY AND PHARMACOLOGY LOUIS S. HARRIS Dcparlmcnl of Pharmacology, Medical College of Virginia, Virginia Commonwealth Unwersity, Richmond, VA 23298 (U.S.A.) SUMMARY The substances under review are a heterogenous set of compounds from a pharmacological point of view, though many have a common phenylethyl- amine structure. Variations in structure lead to marked changes in potency and characteristic action. The introductory material presented here is meant to provide a set of chemical and pharmacological highlights of the 28 substances under con- sideration. The most commonly used names or INN names, Chemical Abstract (CA) names and numbers, and elemental formulae are provided in the accompanying figures. This provides both some basic information on the substances and a starting point for the more detailed information that follows in the individual papers by contributors to the symposium. Key words: Stimulants, their chemistry and pharmacology - Hallucinogens, their chemistry and pharmacology INTRODUCTION Cathine (Fig. 1) is one of the active principles of khat (Catha edulis). The structure has two asymmetric centers and exists as two geometric isomers, each of which has been resolved into its optical isomers. In the plant it exists as d-nor-pseudoephedrine. It is a typical sympathomimetic amine with a strong component of amphetamine-like activity. The racemic mixture is known generically in this country and others as phenylpropanolamine (dl- norephedrine). It is widely available as an over-the-counter (OTC) anti- appetite agent and nasal decongestant. -

PRODUCT MONOGRAPH ORCIPRENALINE Orciprenaline Sulphate Syrup House Standard 2 mg/mL 2-Adrenergic Stimulant Bronchodilator AA PHARMA INC. DATE OF PREPARATION: 1165 Creditstone Road, Unit #1 April 10, 2014 Vaughan, Ontario L4K 4N7 Control Number: 172362 1 PRODUCT MONOGRAPH ORCIPRENALINE Orciprenaline Sulfate Syrup House Standard 2 mg/mL THERAPEUTIC CLASSIFICATION 2–Adrenergic Stimulant Bronchodilator ACTIONS AND CLINICAL PHARMACOLOGY Orciprenaline sulphate is a bronchodilating agent. The bronchospasm associated with various pulmonary diseases - chronic bronchitis, pulmonary emphysema, bronchial asthma, silicosis, tuberculosis, sarcoidosis and carcinoma of the lung, has been successfully reversed by therapy with orciprenaline sulphate. Orciprenaline sulphate has the following major characteristics: 1) Pharmacologically, the action of orciprenaline sulphate is one of beta stimulation. Receptor sites in the bronchi and bronchioles are more sensitive to the drug than those in the heart and blood vessels, so that the ratio of bronchodilating to cardiovascular effects is favourable. Consequently, it is usually possible clinically to produce good bronchodilation at dosage levels which are unlikely to cause cardiovascular side effects. 2 2) The efficacy of the bronchodilator after both oral and inhalation administration has been demonstrated by pulmonary function studies (spirometry, and by measurement of airways resistance by body plethysmography). 3) Rapid onset of action follows administration of orciprenaline sulphate inhalants, and the effect is usually noted immediately. Following oral administration, the effect is usually noted within 30 minutes. 4) The peak effect of bronchodilator activity following orciprenaline sulphate generally occurs within 60 to 90 minutes, and this activity lasts for 3 to 6 hours. 5) Orciprenaline sulphate taken orally potentiates the action of a bronchodilator inhalant administered 90 minutes later, whereas no additive effect occurs when the drugs are given in reverse order. -

J Forensic Sci Criminol 1(3): 301. doi: 10.15744/2348- 9804.1.301 Received Date: September 27, 2013 Accepted Date: December 11, 2013 Published Date: December 16, 2013 Abstract A small set of amphetamines has been analyzed by gas chromatography (GC) high-resolution time-of-flight mass spectrometry (TOFMS) using a microplasma photoionization (MPPI) soft-ionization source. This plasma-based, wavelength selectable ionization source enables ionization of the test compounds and their corresponding derivatives at ~8-12 eV that is a softer alternative to electron ionization at 70 eV. Three plasma gases were used in this study: Xe plasma that emits photons at resonance lines of 9.57 eV and 8.44 eV; Kr plasma at 10.63 eV and 10.02 eV, and Ar plasma at 11.82 eV and 11.61 eV. Derivatization of the test compounds with trifluoroacetic anhydride and α-methoxy-α-(trifluoromethyl)-phenylacetyl pyrazole was evaluated because the MPPI mass spectra of the underivatized amphetamines yield primarily iminium ions, which make the identification of the test compounds by GC-TOFMS inconclusive.
