    Plant alkaloids

    Alkaloids alkaloids are a very mixed group of plant constituents that contain a nitrogen- bearing molecule that makes them particularly pharmacologically active. despite this chemical similarity, the structures and functions vary so widely it would be very silly to link all " alkaloids" together. raffauf ( plant alkaloids: a guide to their discovery and distribution, 1996), more than 10, 000 different alkaloids have been discovered in species from over 300 plant families. alkaloids often contain one or more rings of carbon atoms, usually with a nitrogen atom in the ring. alkaloids used for cancer treatment are a major part of the chemotherapy arsenal. in addition to compounds taken directly from plants, hemisynthesized congeners inspired by natural materials have also found use. alkaloids tend to be cell- cycle specific, although their mechanism at the biochemical level differs from medicine to medicine. the plant alkaloid anticancer drug class is discussed. vinblastine- - ( velban). mechanism of action: microtubule depolymerization. alkaloids are derived from plant sources, they are basic, they contain one or more nitrogen atoms ( usually in a heterocyclic ring) and they usually have a marked physiological action. function of alkaloids: the purpose of existence of alkaloids in plant i.

    their functions in plants is uncertain. plant alkaloid chemotherapy is an effective treatment and there are cases when cancer patients survive using this treatment. though it is an amazing treatment, yet there are certain side effects, which a person will face while going through this chemotherapy. other alkaloids are produced by small animals such as centipedes, ants, ladybugs, etc. alkaloids in plants. most of the alkaloids, however, belong to the vegetable kingdom, so that 10% of plant species contain some of these compounds. Cbd oil cause nausea. the first alkaloid to be isolated and crystallized was the potent active constituent of the opium poppy, morphine, in about 1804. alkaloids are often classified on the basis of their chemical structure. for example, those alkaloids that plant alkaloids contain a ring system called indole are known as indole alkaloids. the podophyllotoxins are derived from the may apple plant.

    camptothecan analogs are derived from the asian " happy tree" ( camptotheca acuminata). podophyllotoxins and camptothecan analogs are also known as topoisomerase inhibitors, which are used in certain types of chemotherapy. the plant alkaloids are cell- cycle specific. alkaloids are generated by various living organisms, especially by higher plants – about 10 to 25% of those contain alkaloids. therefore, in the past the term " alkaloid" was associated with plants. the alkaloids content in plants is usually within a few percent and is inhomogeneous over the plant tissues.
