Cerrado, we isolated novel alkaloids 1 and 2, along with known compounds epicatechin,
ursolic acid, and oleanolic acid, from Galianthe ramosa. Alkaloid 2 inhibited malate synthase
from the pathogenic fungus Paracoccidioides spp. This enzyme is considered an important
molecular target because it is not found in humans. Molecular docking simulations were
used to describe the interactions between the alkaloids and malate synthase.
