1. Avaliação in vitro da atividade antineoplásica do ácido lecanórico e de seus produtos de modificação estrutural / Evaluation in vitro of antineoplasic activity of lecanoric acid and their products of estructural modification
Lichens are a symbiotic association of a fungus and one or more photosynthetic partners. Phenolic substances from lichens exhibit a wide range of biological actions, including antimicrobial, antineoplasic, and cytotoxic activities. The purpose of this study was evaluate in vitro the antineoplasic activity of orsellinates obtained from estructural modificatio

2. In vitro evaluation of the antimicrobial activity of lichen metabolites as potential preservatives.
Antimicrobial screening of several lichen species and subsequent isolation and structure elucidation of active compounds revealed that the hydrolysis products of certain lichen metabolites, i.e., depsides, were active against gram-negative bacteria and fungi as well as gram-positive bacteria. The active constituents isolated from Stereocaulon alpinum and Pel
