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.
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 ...
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]
Vinca major is a commonly grown ornamental plant in temperate gardens for its evergreen foliage, spring flowers, and groundcover or vine use. Many cultivars are available, with differences in flowers, such as white to dark violet flowers, and different patterns and colors of variegated foliage.
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]
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 ...
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 .
Vinca herbacea is a herbaceous perennial growing as a trailing vine, spreading along the ground and rooting along the stems to form clonal colonies, growing up to 10–20 centimetres (4–8 in) high. The leaves are opposite, lanceolate, 1–5 cm ( 1 ⁄ 2 –2 in) long and 0.2–3 cm ( 1 ⁄ 8 – 1 + 1 ⁄ 8 in) broad, glossy green with an ...
