Abstract

Annonaceae is one of the richest families of wood component of the Brazilian savannas. Among the commonest species of the family are Annona coriacea, A. crassiflora, A. dioica, Duguetia furfuracea and Xylopia aromatica. One of the secondary metabolites present in the family is acetogenin, a polyketide of 35 to 37 carbons connected to a ³-lactone. The hypothesis of the present project is that acetogenins isolated from A. coriacea, A. crassiflora, A. dioica, D. furfuracea and X. aromatica should present pesticide activities. To test this hypothesis, ethylic extracts of the species will be carried out and chromatographic fractionated until the purification and isolation of the acetogenins. The extracts, fractions and compounds will be used in bioassays of allelopathic (coleoptile elongation, seeds germination and seedling growth inhibition), bactericidal, fungicidal (respiration and mycelial growth inhibition) and antiviral (reverse transcriptase inhibition) activity. Besides, initial studies of combinatorial biosynthesis involving the acetogenins of Annonaceae will be implemented and they will allow the increase of the knowledge about their production and mode of action, besides pave the way to the manufacture in large scale.
