Question: give the importance of alkaloids in pharmacy and medicine

title: Alkaloid
text: Alkaloids are produced by a large variety of organisms including bacteria , fungi , plants , and animals . They can be purified from crude extracts of these organisms by acid - base extraction . Alkaloids have a wide range of pharmacological activities including antimalarial ( e.g. quinine ) , antiasthma ( e.g. ephedrine ) , anticancer ( e.g. homoharringtonine ) , cholinomimetic ( e.g. galantamine ) , vasodilatory ( e.g. vincamine ) , antiarrhythmic ( e.g. quinidine ) , analgesic ( e.g. morphine ) , antibacterial ( e.g. chelerythrine ) , and antihyperglycemic activities ( e.g. piperine ) . Many have found use in traditional or modern medicine , or as starting points for drug discovery . Other alkaloids possess psychotropic ( e.g. psilocin ) and stimulant activities ( e.g. cocaine , caffeine , nicotine , theobromine ) , and have been used in entheogenic rituals or as recreational drugs . Alkaloids can be toxic too ( e.g. atropine , tubocurarine ) . Although alkaloids act on a diversity of metabolic systems in humans and other animals , they almost uniformly evoke a bitter taste .
