| solanapyrone analogues from a hawaiian fungicolous fungus. | four new solanapyrone analogues (solanapyrones j-m; 1-4) have been isolated from an unidentified fungicolous fungus collected in hawaii. the structures and relative configurations of these compounds were determined by analysis of 1d nmr, 2d nmr, and ms data. solanapyrone j (1) showed antifungal activity against aspergillus flavus and fusarium verticillioides, while both 1 and 2 showed activity against staphylococcus aureus and candida albicans. | 2007 | 17663585 |
| hymenopsins a and b and a macrophorin analogue from a fungicolous hymenopsis sp. | hymenopsin a (1), hymenopsin b (2), and a new macrophorin analogue, 2',3'-epoxy-13-hydroxy-4'-oxomacrophorin a (3), have been isolated from a fungicolous isolate of hymenopsis sp. (myc-1703; nrrl 37638). the structures and relative configurations of these compounds were assigned on the basis of 2d nmr and ms data, and the identity of 1 was confirmed by x-ray crystallographic analysis. the absolute configuration of 2 was proposed on the basis of cd analysis using both empirical and computational ... | 2010 | 19928955 |
