Aromatic compounds produced by Periconia atropurpurea, an endophytic fungus associated with Xylopia aromatica

Compounds 1 and 2 were produced by the endophytic fungus Periconia atropurpurea which is associated with Xylopia aromatica, a native plant of the Brazilian Cerrado. Their structures were established on the basis of comprehensive spectroscopic analyses, mainly by 1D and 2D NMR spectroscopic experiments. Compound 2 showed significant activity when evaluated against human cervix tumor cell lines.
