Protabase Record Display Datura Stramonium L
Protabase Record display www.prota.org Datura stramonium L. Protologue Sp. pl. 1: 179 (1753). Family Solanaceae Chromosome number 2n = 24 Vernacular names Thorn apple, green thorn apple, Jimson weed, Jamestown weed, devil’s apple, devil’s trumpet, stramonium (En). Pomme épineuse, stramoine, datura, feuille du diable, herbe du diable (Fr). Figueira do inferno, pomo espinhoso, erva dos bruxos, palha verde, estramonio (Po). Muranha (Sw). Origin and geographic distribution Datura stramonium is native to the Americas and has been introduced in many tropical, subtropical and even temperate regions. It is a naturalized weed in many African countries, but is probably seriously under-reported. Uses Datura stramonium and Datura metel L. have largely similar medicinal uses throughout the world. The most widely known use of Datura stramonium and of other Datura species is for relieving asthma, cough, tuberculosis and bronchitis by smoking the dried leaves, roots or flowers. ‘Asthma cigarettes’ have been shown to be very effective in some cases, but in other cases they had little or no effect. Cigarettes made with the leaves are also used to treat Parkinson’s disease. A decoction or infusion of leaves is given as a sedative to mental and schizophrenic patients. The leaves are applied as a dressing to cure rheumatic pain, swellings, wounds, gout, burns, ingrown toe-nails, fungal infections, tumours and ulcers. Dried pulverized leaves are dusted on wounds or applied after mixing the powder with fat or Vaseline. In DR Congo pounded fresh root and fresh leaves are soaked in water and the liquid is given in enema as an abortifacient. -
Blockade of Muscarinic Acetylcholine Receptors Facilitates Motivated Behaviour and Rescues a Model of Antipsychotic- Induced Amotivation
www.nature.com/npp ARTICLE Blockade of muscarinic acetylcholine receptors facilitates motivated behaviour and rescues a model of antipsychotic- induced amotivation Jonathan M. Hailwood 1, Christopher J. Heath2, Benjamin U. Phillips1, Trevor W. Robbins1, Lisa M. Saksida3,4 and Timothy J. Bussey1,3,4 Disruptions to motivated behaviour are a highly prevalent and severe symptom in a number of neuropsychiatric and neurodegenerative disorders. Current treatment options for these disorders have little or no effect upon motivational impairments. We assessed the contribution of muscarinic acetylcholine receptors to motivated behaviour in mice, as a novel pharmacological target for motivational impairments. Touchscreen progressive ratio (PR) performance was facilitated by the nonselective muscarinic receptor antagonist scopolamine as well as the more subtype-selective antagonists biperiden (M1) and tropicamide (M4). However, scopolamine and tropicamide also produced increases in non-specific activity levels, whereas biperiden did not. A series of control tests suggests the effects of the mAChR antagonists were sensitive to changes in reward value and not driven by changes in satiety, motor fatigue, appetite or perseveration. Subsequently, a sub-effective dose of biperiden was able to facilitate the effects of amphetamine upon PR performance, suggesting an ability to enhance dopaminergic function. Both biperiden and scopolamine were also able to reverse a haloperidol-induced deficit in PR performance, however only biperiden was able to rescue the deficit in effort-related choice (ERC) performance. Taken together, these data suggest that the M1 mAChR may be a novel target for the pharmacological enhancement of effort exertion and consequent rescue of motivational impairments. Conversely, M4 receptors may inadvertently modulate effort exertion through regulation of general locomotor activity levels. -

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. -
Ketamine Psychedelic Psychotherapy
KETAMINE PSYCHEDELIC PSYCHOTHERAPY EVGENY KRUPITSKY AND ELI KOLP INTRODUCTION Ketamine hydrochloride is a general anesthetic which has been used for noncon- ventional applications in substance abuse rehabilitation because of its psychedelic properties. This chapter summarizes the results of the research on KPP (ketamine psychedelic psychotherapy), principally with alcoholics and heroin addicts. Mechanisms underlying the effects of hallucinogen-assisted psychotherapy are addressed. Research illustrates how the temporary but effective anti-addictive benefits for a short period of time can be extended for longer periods of time to improve overall long-term adjustment and level of functioning. Ketamine hydrochloride, a prescription drug used for general anesthesia, induces profound psychedelic experiences when administered in sub-anesthetic .doses. Ketamine was originally synthesized in 1962 by the American chemist Calvin Stevens, and in 1966 Parke-Davis patented it for use as an anesthetic in humans. Ketamine became the most widely used anesthetic during the Vietnam War when American anesthesiologists and surgeons became familiar with the agent. In 1970, the U.S. Food and Drug Administration approved the use of ketamine with children, adults, and the elderly. Since that time, ketamine has been widely used in hospitals and for office procedures because of its large margin of safety, rapid onset, and short duration of action. More than 7,000 68 TREATTNG SUBSTANCE ABUSE published reports describe ketamine's high level of effectiveness and its biologi- cal safety (Shapiro et al. 1972; Reich and Silvay 1989; Ross and Fochtman 1995; Dachs and Innes 1997; Bauman et al. 1999; Ersek 2004). Clinical studies have detected no long-term impairment of behavior or personality functioning as a result of ketamine use (Siegal 1978). -

Six cytotoxic extracts and one potential antimalarial were selected for fractionation, and yielded a number of bioactive compounds which were characterized by spectroscopy methods. Craspidospermum verticillatum (Apocynaceae) yielded four known indole alkoids. Casimirella sp (Icacinaceae) gave three new and five known diterpenoids. Pentopetia androsaemifolia (Apocynaceae) afforded one new and three known cardenolide glycosides. Physalis angulata (Solanaceae) yielded seven known physalins. Roupellina boivinnii (Apocynaceae) yielded four known and three new cardenolide glycosides, and three known cucurbitacins were isolated from Octolepis aff. dioica (Thymelaeaceae). In addition to these structural studies, a synthetic approach to lucilactaene, a cell cycle inhibitor was developed.

Pharmacogn J. 2018; 10(2): 285-292 A Multifaceted Journal in the field of Natural Products and Pharmacognosy Original Article www.phcogj.com | www.journalonweb.com/pj | www.phcog.net Phytochemical Analysis, Antioxidant Assay and Antimicrobial Activity in Leaf Extracts of Cerbera odollam Gaertn Abinash Sahoo, Thankamani Marar* ABSTRACT Introduction: In the current study, methanol and aqueous extracts of leaf of Cerbera odollam Gaertn were screened for its antibacterial, antifungal, phytochemicals and antioxidant ac- tivities. Phytochemical constituents were investigated both qualitatively and quantitatively. Methods: The leaf extracts of Cerbera odollam Gaertn were prepared by drying and extracted using Soxhlet apparatus into methanol and aqueous media, which were subjected to phyto- chemical screening. Total phenols, tannins, flavanols, alkaloids and its antioxidant activity were determined using spectroscopic techniques. Antimicrobial activity were determined using well diffusion method. Results: Aqueous extract exhibits higher content of phenols, tannins, flavanols and alkaloids, whereas methanol extract exhibits higher content of anthocyanin and cardiac glycoside respectively. Aqueous extract exhibits higher inhibitory concentration (IC %) value for DPPH (2, 2-Diphenyl-1-picrylhydrazyl) and H2O2 radical scavenging assay and reduc- ing power (RP) assay. The methanol extracts exhibited higher inhibitory concentration (IC %) value in SO and NO radical scavenging assay, exhibiting antioxidant properties in five antioxi- dant models that were investigated. The methanol extract showed some antibacterial activity against Bacillus subtilis, Staphylococcus aureus, Salmonella typhi and Escherichia coli with inhibitory zone ranging from 2 mm to 3 mm, whereas the aqueous extract showed no activity. Abinash Sahoo, High antifungal activity was found against Saccharomyces cerevisiae and Candida albicans for methanol extract and moderate for aqueous extract with inhibitory zone ranging from 9mm Thankamani Marar* to 26 mm.
