Antioxidant, anti-inflammatory and cytotoxic/antitumoral bioactives from the phylum Basidiomycota and their possible mechanisms of action.

Biologically active compounds from species of the phylum Basidiomycota have been shown a wide range of pharmacological activities and provide a vast reservoir of potential innovational drugs. The aim of this review is to discuss some mechanisms of action involved in antioxidant, anti-inflammatory and cytotoxic/antitumoral activities attributed to the bioactive compounds from species of the phylum Basidiomycota. We show that isolated compounds from extracts, secondary metabolites and polysaccharides that presented antioxidant properties have mechanisms of action involved in the elimination/capture of free radicals and reduction of lipid peroxidation. Also, some bioactives with anti-inflammatory activity were reported to enhance innate and cell-mediated immune responses. Finally, compounds that presented cytotoxic/antitumoral activity induces increased free radical production, collapse of the mitochondrial membrane potential and increased expression of proteins responsible for cell cycle arrest and apoptosis. Investigating the mechanisms of action of biologically active compounds will facilitate further efforts to accelerate the discovery of novel therapeutic strategies.
