  • coniine
  • Socrates - The philosopher, charged with religious heresy and with corrupting the morals of local youth, died by hemlock poisoning (the active chemical is the alkaloid coniine). (toxipedia.org)
  • organic
  • Diagram of EphedrineAn alkaloid is a nitrogenous organic molecule that has a pharmacological effect on humans and animals. (biology-online.org)
  • Alkaloids are found as secondary metabolites in plants (e.g., in potatoes and tomatoes), animals (e.g., in shellfish) and fungi, and can be extracted from their sources by treatment with acids (usually hydrochloric acid or sulfuric acid, though organic acids such as maleic acid and citric acid are sometimes used). (biology-online.org)
  • plant
  • Camalexin is a simple indole alkaloid produced by the plant Arabidopsis thaliana, often used as a model for plant biology. (wikipedia.org)
  • active
  • We have found that N -oxidation by peroxyacids of a large number of biologically active tertiary amines including alkaloids in buffered in aqueous solutions realizes by means of the mechanism of specific acid-base catalysis. (gisap.eu)
  • The relationship between ergot and ergotism was established only in 1717, and the alkaloid ergotamine, one of the main active ingredients of ergot, was isolated in 1918. (wikipedia.org)
  • usually
  • citation needed] Strychnine poisoning in animals usually occurs from ingestion of baits designed for use against gophers, moles, and coyotes. (wikipedia.org)
  • Alkaloids are usually classified by their common molecular precursors, based on the metabolic pathway used to construct the molecule. (biology-online.org)
  • method
  • Quantitative yield N -oxide alkaloids estimated by polarography method using calibration curve without isolating them from solution. (gisap.eu)
  • The method of polarography shows that the increase of the concentration of the forming N -oxide of the alkaloid during the reaction is directly proportional to the decrease the diperoxy acid concentration in the solution. (gisap.eu)
  • made
  • No attempt to determine the second-order rate constant for the reaction of alkaloids with mono- or diperoxy carboxylic acids was made. (gisap.eu)
  • toxic
  • In high doses, strychnine is very toxic to humans and many other animals (LD50 = 16 mg/kg in humans, 1-2 mg/kg orally in rats and mice), and poisoning by inhalation, swallowing, or absorption through eyes or mouth can be fatal. (wikipedia.org)
  • found
  • We have found that N -oxidation by peroxyacids of a large number of biologically active tertiary amines including alkaloids in buffered in aqueous solutions realizes by means of the mechanism of specific acid-base catalysis. (gisap.eu)
  • Partial dehydrogenation of laudanosine will lead to papaverine , the alkaloid found in the opium poppy plant ( Papaver somniferum ). (infogalactic.com)
  • Alkaloids are found as secondary metabolites in plants (e.g., in potatoes and tomatoes), animals (e.g., in shellfish) and fungi, and can be extracted from their sources by treatment with acids (usually hydrochloric acid or sulfuric acid, though organic acids such as maleic acid and citric acid are sometimes used). (biology-online.org)
  • Although their assignment to the alkaloid is not universally accepted, they are both found in plants and animals. (wikipedia.org)
  • conditions
  • This was followed up with another old-school reaction-a deconjugative double alkylation of the enone-using conditions cribbed from R. B. Woodward's 1954 lanesterol synthesis. (brsmblog.com)
