Although cells submitted to differentiation show slower growth than those that are not differentiated, some studies demonstrated that their morphology may have an influence; for example, it has been established that the cylindrical i. Principles of Oncologic Pharmacotherapy”. About kg of dried leaves are used to isolate 1 g of vinblastine and two tons of macerated leaves provide 1 g of the active principle required for the treatment of a child with leukemia for 6 weeks.
It lacks tannins, cardiac glycosides, steroids catasterone, brasinolide and monoterpene glucosides loganin, secologanin, sweroside, dioxyl and dihydro-loganin . Para-nitrophenyl phosphate pNPP was used as a substrate for the trial on phosphatase activity the recombinant enzyme PTP-1B and it was added at the start of the reaction .
They have been used to treat diabetes, high blood pressure and have been used as disinfectants and anti-cancer. Biotechnology in Agriculture and Forestry DFT studies of nano anticancer on vinblastine and vincristine molecules. The expanding universe of alkaloid biosynthesis.
It has been also used for treating fever, malaria, menstrual cycle regulation, as a euphoric drug , as tranquilizer, and for its ability to reduce arterial blood pressure . Vinflunine is also a new synthetic vinca alkaloid, which has been approved in Europe for the treatment binca second-line transitional cell carcinoma of the urothelium is being developed for other malignancies. Quantification of metabolic fluxes for metabolic engineering of plant products.

Anti-helminthic activity The infections produced by helminths are chronic diseases affecting human beings. This plant is also found in other tropical and subtropical regions such as: On the other hand, it is important to remark that in feedback studies, it was found that high concentrations of the intermediaries or precursors of metabolites are able to generate greater accumulation of alkaloids in the biosynthesis pathway. The biosynthesis route of the indole alkaloids has been studied by De-Luca and Cutler .
It has been applied for clinical development in the wide spectrum of solid tumors. Furthermore, phytochemical ingredients were identified, such as: In Cuba, Puerto Rico, Jamaica and other islands, the aqueous extract of the white flower is commonly used as an eye wash for infants and as fomentation for easing eye diseases [39, 43].
