ABSTRACT: Our review highlights the most recent developments in ionic liquid (IL) chemistry where the “well-known” description of IL properties sometimes proves to be inaccurate. However, in the authors’ opinion, all these new research developments concerning ionic liquid properties serve to update knowledge on the typical physical and chemical properties of ILs, which is significant to both theoretical research and industrial applications.

Due to this prevailing situation, drought and climate resistant crops like sorghum (Sorghum bicolor (L) Moench) can adequately contribute to food security. The versatility and importance of sorghum is well reflected in its use as a major food source for millions of people in sub-Saharan Africa.

  • Etoxadrol-Meta-Isothiocyanate: a Potent, Enantioselective, Electrophilic Affinity Ligand for the Phencyclidine-Binding Site
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Elsevier - Publisher Connector Volume 238, number 2, 369-374 FEB 06377 October 1988 Etoxadrol-meta-isothiocyanate: a potent, enantioselective, electrophilic affinity ligand for the phencyclidine-binding site Andrew Thurkauf, Mariena V. Mattson, Philip N. Huguenin*, Kenner C. Rice and Arthur E. Jacobson Section on Drug Design and Synthesis, Laboratory of Neuroscience, National Institute of Diabetes, Digestive and Kidney Diseases, National Institutes of Health, Bethesda, IUD 20892, USA Received 17 August 1988 Etoxadrol-mera-isothiocyanate (2S,4S,692-ethyl-2-(3-isothiocyanatophenyl)-2-pi~ridyl)1,3-dioxolane, 4n) has been synthesized and characterized as an irreversible ligand for the phencyclidine (PCP)-binding site. It is the first chiral elec- trophilic affinity ligand for this site to have been described. This affinity ligand is based upon etoxadrol, a 1,3-dioxolane known to have PCP-like effects in vivo and in vitro. Etoxadrol-meta-isothiocyanate was found to be four-five times more potent in vitro than metaphit (1-[1-(3-isothiocyanatophenyl)cyclohexyl]pi~~dine), the only previously known electro- philic affinity ligand for the PCP-binding site. The binding was shown to be highly enantioselective for etoxadrol-meta- isothiocyanate (4a). The 2R,4R,6R-enantiomer of 4a was essentially inactive. The ability of the 2S,4$69enantiomer (4a) to interact with the benzodiazepine, muscarinic, and mu opioid receptor systems was also examined, and it was found not to interact with these receptor systems. It seems likely that 4a will prove to be a valuable tool in the study of structure and function of the PCP-binding site.

  • Sympathomimetic Anesthetics
    SYMPATHOMIMETIC ANESTHETICS GRAHAM CHEN, SC.D., M.D. A NEW TYPE of general anaesthetic drug has been developed in recent years. These drugs produce surgical anaesthesia without causing depression of respiratory and cardiovascular functions. Slight hypertension and taehycardia usually occur fol- lowing their intravenous administration. Mental confusion, dreaming, and a feel- ing of body dissociation are expressed by some individuals during the recovery period. Two classes of compounds containing a basic amine moiety have been shown to possess such properties: arylcycloalkylamines and 2-(2,2 substituted 1,3 dioxo- lan-4-yl) piperidines. Phencyelidine and ketamine belong to the first category, and dexoxadrol and etoxadrol to the latter. The structures of these drugs are shown in Figure 1. The anaesthetic and some other properties of the two classes of chemi- cals are remarkably similar; they may be considered together insofar as their principal pharmacologic actions are concerned. The purpose of this communication is to describe the neuropharmacological characteristics of these drugs, to indicate structure-activity relationships, and to discuss the mode of their anaesthetic actions. PHARMACOLOGY The progressive central effects of arylcycloalkylamines and 2-(2,2 substituted 1,3 dioxolan-4-yl) piperidines administered to animals in increasing doses gen- erally are excitation, ataxia, catalepsy, general anaesthesia and conwdsions. The degree of stimulation and depression varies with animal species and different compounds. Excitation is a prominent initial effect in rats and mice. It does not usually occur in primates, including man. 1- ~ Ataxia is a concomitant effect in rats and mice, and may occur in other species even in the absence of excitement.1 -3 Catalepsy, similar to that produced by bulbocapnine, is an outstanding central effect of these agents in all species including man.

  • Receptor Binding Profile of Quinupramine, a New Tricyclic Antidepressant
    Receptor Binding Profile of Quinupramine, a New Tricyclic Antidepressant Hirohiko SAKAMOTO*, **, Nobuharu YOKOYAMA*, **, Shigekatsu KOHNO* and Katsuya OHATA* *Department of Pharmacology , Kyoto Pharmaceutical University, Yamashina, Kyoto 607, Japan **Biochemical Division , Research Laboratories, Nippon Shoji Kaisha, Ltd., Ibaraki, Osaka 567, Japan Accepted August 17, 1984 Abstract-The receptor binding profile, composed of the K;-values measured in eight different receptor binding models using rat brain membranes, is reported for the new tricyclic antidepressant quinupramine, 10,11 -dihydro-5-(3-quinuclidinyl) 5H-dibenz[b, f]azepine, and three reference compounds with a tertiaryamine side chain. Quinupramine was found to possess high affinity for muscarinic cholinergic and histamine Ht receptor binding sites in rat brain, whereas its affinity for imipramine binding sites was only one seventieth that of imipramine. Receptor binding profiles of the reference compounds were almost similar to that of quinupramine , except in the case of imipramine binding sites. Tricyclic antidepressants are known to be clidinyl [phenyl-4-3H]benzilate (42 Ci/ inhibitors of norepinephrine and serotonin mmol), [pyridinyl-5-3H]pyrilamine (28 Ci/ reuptake into nerve terminals. This action was mmol) and [phenyl-4-3H]spiperone (17 Ci/ also believed to be responsible for their mmol) were purchased from Amersham , therapeutic effects and probably involved Buckinghamshire, England. [N-methyl-3H] presynaptic sites (1). In addition, recent imipramine hydrochloride (75 Ci/mmol) was reports suggest a direct interaction of tricyclic from New England Nuclear, Boston, MA , antidepressants with a variety of seemingly U.S.A. 3H-Ligands were stored at -20°C postsynaptic sites. These evidences have and diluted in standard assay buffer before been obtained through the interaction of use.
