The quest for promising substances through
rational selection of natural products as anticancer drugs
source is an alternative subsidy to cancer treatment and
have guided numerous research for new medicines
(Magalhães, 2005). Algae, fungi, lichens, fungi and
vascular plants are major sources for the research of new
bioactive molecules through the direct use of secondary
metabolites or biosynthesis-derived compounds produced
in order to increase effectiveness and absorption or to
decrease toxicity (Hostettman et al., 1997).
