give the importance of alkaloids in pharmacy and medicine
Alkaloid 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),[6] cholinomimetic (e.g. galantamine),[7] vasodilatory (e.g. vincamine), antiarrhythmic (e.g. quinidine), analgesic (e.g. morphine),[8] antibacterial (e.g. chelerythrine),[9] and antihyperglycemic activities (e.g. piperine).[10] 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),[11] and have been used in entheogenic rituals or as recreational drugs. Alkaloids can be toxic too (e.g. atropine, tubocurarine).[12] Although alkaloids act on a diversity of metabolic systems in humans and other animals, they almost uniformly evoke a bitter taste.[13]
Doctor of Pharmacy A Doctor of Pharmacy (Pharm.D.; New Latin Pharmaciae Doctor) is a professional doctorate degree in pharmacy. In some countries, it is a first professional degree, and a prerequisite for licensing to exercise the profession of pharmacist.
