Vinca alkaloids are now produced synthetically and used as drugs in cancer therapy and as immunosuppressive drugs. These compounds include vinblastine, vincristine, vindesine, and vinorelbine. Additional researched vinca alkaloids include vincaminol, vineridine, and vinburnine.
The cancer treatment drug topotecan is a synthetic chemical compound similar in chemical structure to camptothecin which is found in extracts of Camptotheca (happy tree). [7] Catharanthus roseus. Vinca alkaloids were originally manufactured by extracting them from Catharanthus roseus (Madagascar Periwinkle). [1] Podophyllum spp.
1.08 Vinca alkaloids: ... Breast cancer, lymphoma, acute lymphoblastic leukaemia, ... which is essential for cell growth and survival.
Vinblastine is a chemical analogue of vincristine [17] [20] [25] and is also used to treat various forms of cancer. [26] Dimeric alkaloids such as vincristine and vinblastine are produced by the coupling the smaller indole alkaloids vindoline and catharanthine. [17] [27] In addition, the nootropic agent vincamine is derived from V. minor.
Vincristine is delivered via intravenous infusion for use in various types of chemotherapy regimens. [3] Its main uses are in non-Hodgkin's lymphoma as part of the chemotherapy regimen CHOP R-CVP, Hodgkin's lymphoma as part of MOPP, COPP, BEACOPP, or the less popular Stanford V chemotherapy regimen in acute lymphoblastic leukemia (ALL), and in treatment for nephroblastoma as well as the ...
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 ...
Vinca alkaloids are derived from the Madagascar periwinkle, Catharanthus roseus, [48] [49] formerly known as Vinca rosea. They bind to specific sites on tubulin, inhibiting the assembly of tubulin into microtubules. The original vinca alkaloids are natural products that include vincristine and vinblastine.
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.
