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 ...
The vinca alkaloids include at least 86 alkaloids extracted from plants in the genus Vinca. [ 16 ] [ 17 ] [ 18 ] The chemotherapy agent vincristine is extracted from a closely related species, Catharanthus roseus , [ 19 ] [ 20 ] [ 21 ] and is used to treat some leukemias , [ 22 ] lymphomas , [ 23 ] and childhood cancers, [ 24 ] as well as ...
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]
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 ...

The alkaloids are a large group of natural products which are classified according to the part-structure which members of a particular group contain. Akuammicine is a monoterpene indole alkaloid of the Vinca sub-group which shares a common biosynthesis with other members, namely that they are derived from strictosidine.
The Vinca alkaloids bind to the β-subunit of tubulin dimers at a distinct region called the Vinca-binding domain. They bind to tubulin rapidly, and this binding is reversible and independent of temperature (between 0 °C and 37 °C). In contrast to colchicine, vinca alkaloids bind to the microtubule directly.
