Abstract

Four new altenuene derivatives called dihydroaltenuenes A ( 1 ) and B ( 2 ), and dehydroaltenuenes A ( 3 ) and B ( 4 ), along with five known compounds, including isoaltenuene ( 5 ), altenuene ( 6 ) and 5′-epialtenuene ( 7 ), were isolated from cultures of an unidentified freshwater aquatic fungal species in the family Tubeufiaceae. The structures of 1 – 4 were determined by analysis of NMR and MS data. The relative stereochemistry was determined on the basis of 1 H NMR J -values and NOE data, while the absolute configuration of a representative member of the group ( 5 ) was assigned by CD spectral analysis of its bis -N,Ndimethylaminobenzoate derivative. Compounds 1 , 3, 4, 5 , and 6 showed antibiotic activity against Gram-positive bacteria.
