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. [1]
Vinca (/ ˈ v ɪ ŋ k ə /; [2] Latin: vincire "to bind, fetter") is an Old World genus of flowering plants in the family Apocynaceae, The English name periwinkle is shared with the related genus Catharanthus (and with the mollusc Littorina littorea). Some Vinca species are cultivated but have also spread invasively.
Catharanthus roseus, known formerly as Vinca rosea, is a main source of vinca alkaloids, now sometimes called catharanthus alkaloids. The plant produces about 130 of these compounds, including vinblastine and vincristine, two drugs used to treat cancer. [8] [9] [10] [11]
The newer semi-synthetic chemotherapeutic agent vinorelbine, used in the treatment of non-small-cell lung cancer, [27] [30] can be prepared either from vindoline and catharanthine [27] [31] or from the vinca alkaloid leurosine, [32] in both cases via anhydrovinblastine. [31] The insulin-stimulating vincoline has been isolated from the plant ...
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
There are also at least 86 alkaloids whose names contain the root "vin" because they are extracted from vinca plants such as Vinca rosea (Catharanthus roseus); [26] these are called vinca alkaloids. [ 27 ] [ 28 ] [ 29 ]
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 ...
