Additional researched vinca alkaloids include vincaminol, vineridine, and vinburnine. Vinpocetine is a semi-synthetic derivative of vincamine (sometimes described as "a synthetic ethyl ester of apovincamine"). [14] Minor vinca alkaloids include minovincine, methoxyminovincine, minovincinine, vincadifformine, desoxyvincaminol, and vincamajine ...
Vincamine is a monoterpenoid indole alkaloid found in the leaves of Vinca minor (lesser periwinkle), comprising about 25–65% of its indole alkaloids by weight. It can also be synthesized from related alkaloids.
Vinca alkaloids were originally manufactured by extracting them from Catharanthus roseus (Madagascar Periwinkle). [1] Podophyllum spp. Two chemotherapy drugs, etoposide and teniposide, are synthetic chemical compounds similar in chemical structure to the toxin podophyllotoxin which is found in Podophyllum peltatum (May Apple). [1] Taxus brevifolia
Vindesine, also termed Eldisine, is a semisynthetic vinca alkaloid derived from the flowering plant Catharanthus roseus. [1] Like the natural (e.g. vinblastine and vincristine) and semisynthetic vinca alkaloids (e.g. vinorelbine and vinflunine) derived from this plant, vindesine is an inhibitor of mitosis that is used as a chemotherapy drug. [2]
Vinblastine is a vinca alkaloid [9] [2] [10] and a chemical analogue of vincristine. [11] [12] It binds tubulin, thereby inhibiting the assembly of microtubules. [13]Vinblastine treatment causes M phase specific cell cycle arrest by disrupting microtubule assembly and proper formation of the mitotic spindle and the kinetochore, each of which are necessary for the separation of chromosomes ...
The first individual alkaloid, morphine, was isolated in 1804 from the opium poppy (Papaver somniferum). [1] Alkaloids are a broad class of naturally occurring organic compounds that contain at least one nitrogen atom. Some synthetic compounds of similar structure may also be termed alkaloids. [2]

Strictosidine is a natural chemical compound and is classified as a glucoalkaloid and a vinca alkaloid.It is formed by the Pictet–Spengler condensation reaction of tryptamine with secologanin, catalyzed by the enzyme strictosidine synthase.
