Catharanthus coriaceus [1] is a species of flowering plant in the dogbane family, Apocynaceae. It is endemic to Madagascar.
Apocynaceae is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison. Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here.
Catharanthus is a genus of flowering plants in the family Apocynaceae. Like the genus Vinca, they are known commonly as periwinkles. There are eight known species. Seven are endemic to Madagascar, though one, C. roseus, is widely naturalized around the world. The eighth species, C. pusillus, is native to India and Sri Lanka. The name Catharanthus comes from the Greek for "pure flower".
Vincristine, also known as leurocristine and marketed under the brand name Oncovin among others, is a chemotherapy medication used to treat a number of types of cancer. This includes acute lymphocytic leukemia, acute myeloid leukemia, Hodgkin's disease, neuroblastoma, and small cell lung cancer among others. It is given intravenously.
Vinca is a genus of flowering plants in the family Apocynaceae, native to Europe, northwest Africa and southwest Asia. The English name periwinkle is shared with the related genus Catharanthus.
Catharanthus roseus, commonly known as bright eyes, Cape periwinkle, graveyard plant, Madagascar periwinkle, old maid, pink periwinkle, rose periwinkle, is a species of flowering plant in the family Apocynaceae. It is native and endemic to Madagascar, but grown elsewhere as an ornamental and medicinal plant. It is a source of the drugs vincristine and vinblastine, used to treat cancer. It was formerly included in the genus Vinca as Vinca rosea.
Vinca alkaloids are a set of anti-mitotic and anti-microtubule alkaloid agents originally derived from the periwinkle plant Catharanthus roseus and other vinca plants. They block beta-tubulin polymerization in a dividing cell.
Vindesine, also termed Eldisine, is a semisynthetic vinca alkaloid derived from the flowering plant Catharanthus roseus. Like the natural and semisynthetic vinca alkaloids derived from this plant, vindesine is an inhibitor of mitosis that is used as a chemotherapy drug. By inhibiting mitosis, vinedsine blocks the proliferation of cells, particularly the rapidly proliferation cells of certain types of cancer. It is used, generally in combination with other chemotherapeutic drugs, in the treatment of various malignancies such as leukaemia, lymphoma, melanoma, breast cancer, and lung cancer.
Rosinidin is an O-methylated anthocyanidin derived from Cyanidin. It is a pigment found in the flowers of Catharanthus roseus and, in lower concentration, in Primula rosea.
Hirsutidin is an O-methylated anthocyanidin, a chemical compound belonging to the anthocyanins. It can be found in Catharanthus roseus where it is the prominent compound in petals and can also be found in callus cultures.
Ajmalicine, also known as δ-yohimbine or raubasine, is an antihypertensive drug used in the treatment of high blood pressure. It has been marketed under numerous brand names including Card-Lamuran, Circolene, Cristanyl, Duxil, Duxor, Hydroxysarpon, Iskedyl, Isosarpan, Isquebral, Lamuran, Melanex, Raunatin, Saltucin Co, Salvalion, and Sarpan. It is an alkaloid found naturally in various plants such as Rauvolfia spp., Catharanthus roseus, and Mitragyna speciosa.
Dominican tea culture combines many customs adapted from various colonial and immigrant cultures that have mingled in Dominica. "Bush teas", made from local herbal plants and often taken for medicinal purposes, are a traditional part of Dominica's culture.
Catharanthus lanceus grows as a perennial herb up to 1 metre (3 ft) tall. Its fragrant flowers feature white or cream corolla lobes turning pink, reddish-violet or pink-magenta. Vernacular names for the plant include "lance-leaf periwinkle". Its habitat is on volcanic or burned soil, hillside rocks and in open woodland on ridges. Catharanthus lanceus is found from 750–2,000 metres (2,500–6,600 ft) altitude. The plant is used in local medicinal treatments for toothache, fever and skin diseases, and also as a diuretic. The species is endemic to Madagascar.
Catharanthus trichophyllus is a species of flowering plant in the family Apocynaceae. It is endemic to Madagascar, where it is most common in northern regions.
Catharanthus scitulus is a species of flowering plant in the family Apocynaceae. It is endemic to Madagascar.
Catharanthus longifolius is a species of flowering plant in the dogbane family, Apocynaceae. It is endemic to Madagascar.
Tabersonine is a terpene indole alkaloid found in the medicinal plant Catharanthus roseus and also in the genus Voacanga. Tabersonine is hydroxylated at the 16 position by the enzyme tabersonine 16-hydroxylase (T16H) to form 16-hydroxytabersonine. The enzyme leading to its formation is currently unknown. Tabersonine is the first intermediate leading to the formation of vindoline one of the two precursors required for vinblastine biosynthesis.
16-Hydroxytabersonine is a terpene indole alkaloid produced by the plant Catharanthus roseus. The metabolite is an intermediate in the formation of vindoline, a precursor needed for formation of the pharmaceutically valuable vinblastine and vincristine. 16-hydroxytabersonine is formed from the hydroxylation of tabersonine by tabersonine 16-hydroxylase (T16H). Tabersonine 16-O-methyltransferase (16OMT) methylates the hydroxylated 16 position to form 16-methoxytabersonine.
Deacetylvindoline is a terpene indole alkaloid produced by Catharanthus roseus. Deacetylvindoline is the product of a hydroxylation of desacetoxyvindoline by deacetoxyvindoline 4-hydroxylase (D4H). It is a substrate for deacetylvindoline O-acetyltransferase (DAT) which acetylates a hydroxy group to form vindoline, one of the two immediate precursors for the formation of the pharmacetucially valuable bisindole alkaloid vinblastine.
Loganic acid is an iridoid. Loganic acid is synthesized from 7-deoxyloganic acid by the enzyme 7-deoxyloganic acid hydroxylase (7-DLH). It is a substrate for the enzyme loganate O-methyltransferase for the production of loganin.
Lochnericine is a major monoterpene indole alkaloid present in the roots of Catharanthus roseus. It also present in Tabernaemontana divaricata.
