P-glycoprotein (Pgp)-mediated drug efflux can yield a multidrug resistance (MDR) phenotype that is associated with poor response to cancer chemotherapy. Pervilleine F, a new tropane alkaloid aromatic ester obtained from a chloroform extract of the roots of Erythroxylum pervillei as the result of
In the study, we have examined the antitumor and antimicrobial activities of the methanol extract, the fractions, a fraction of total alkaloids and two alkaloids isolated from the stem of Erythroxylum caatingae Plowman. All test fractions, except the hexane fractions, showed antimicrobial activity
Plant-derived molecules showing antineoplastic effects have recently gained increased attention as potential adjuvants to traditional therapies for various cancers. Cerrado biome in Brazil contains high floral biodiversity, but knowledge about the potential therapeutic effects of compounds derived
Three tropane alkaloids, 1-3, were isolated from Erythroxylum caatingae, i.e., 6β-benzoyloxy-3α-[(4-hydroxy-3,5-dimethoxybenzoyl)oxy]tropane (1), a new tropane alkaloid, along with the known alkaloids 3α,6β-dibenzoyloxytropane (2) and 6β-benzoyloxy-3α-[(3,4,5-trimethoxybenzoyl)oxy]tropane (catuabine
OBJECTIVE
Antineoplastic effects of molecules derived from plants have recently gained increasing attention as an additive to traditional therapies. The aim of this study was to evaluate the cytotoxic activity of plant extracts from the Brazilian Cerrado biome associated with radiotherapy in head
