Botany, uses, phytochemistry and pharmacology of selected apocynaceae species: It is also effective in the treatment of advanced testicular tumors, breast cancer, Kaposi sarcoma, and the Letterer-Siwe disease . The main structural skeleton of the terpene indole alkaloids together with its biological activity are shown in table 1.
Xlcaloides, the vinca alkaloids are so important for being cancer fighters. The vinblastine works specifically during the metaphase stage of the cell cycle, since the microtubules are components of the mitotic spindle, and the kinetochores that are necessary for the separation of the chromosomes during the anaphase in mitosis.
Furthermore, it shows high anti-plasmodial activity in vitro because of the presence of terpenoids, flavonoids and sesquiterpenes . Vina drugs from the secondary metabolites of higher plants.

This is attributed to the lack of differentiation of tissues, the direct exposure to metabolites or the high permeability of the membrane, but the most important aspect that is not considered is the lack of storage capacity of the synthesized tissue .
