The Madagascan periwinkle Catharanthus roseus L. is the source for a number of important natural products, [1] including catharanthine and vindoline [2] and the vinca alkaloids it produces from them: leurosine and the chemotherapy agents vinblastine [3] and vincristine, [4] all of which can be obtained from the plant.
Vinca difformis in habitat, Cáceres, Spain. Vinca plants are subshrubs or herbaceous, and have slender trailing stems 1–2 m (3 + 1 ⁄ 2 – 6 + 1 ⁄ 2 ft) long but not growing more than 20–70 cm (8– 27 + 1 ⁄ 2 in) above ground; the stems frequently take root where they touch the ground, enabling the plant to spread widely.
Mitotic inhibitors are derived from natural substances such as plant alkaloids, and prevent cells from undergoing mitosis by disrupting microtubule polymerization, thus preventing cancerous growth. Microtubules are long, ropelike proteins, long polymers made of smaller units ( monomers ) of the protein tubulin , that extend through the cell and ...
The natural extraction of vincristine from Catharanthus roseus is produced at a percent yield of less than 0.0003%. For this reason, alternate methods to produce synthetic vincristine are being used. [22] Vincristine is created through the semi-synthesis coupling of indole alkaloids vindoline and catharanthine in the vinca plant. [23]
Hyaluronic acid is already naturally produced by the body, so even when using it in a topical form, the chances of experiencing any negative side effects are very slim.
Vinca minor (common names lesser periwinkle [1] or dwarf periwinkle) is a species of flowering plant in the dogbane family, native to central and southern Europe. Other vernacular names used in cultivation include small periwinkle , common periwinkle , and sometimes in the United States, myrtle or creeping myrtle .
