| citromycetins and bilains a-c: new aromatic polyketides and diketopiperazines from australian marine-derived and terrestrial penicillium spp. | chemical analysis of an australian marine-derived isolate of penicillium bilaii, collected from the huon estuary, port huon, tasmania, yielded the known fungal aromatic polyketides citromycetin (1) and citromycin (2) together with two dihydro analogues, (-)-2,3-dihydrocitromycetin (3) and (-)-2,3-dihydrocitromycin (4). an australian terrestrial isolate of penicillium striatisporum collected near shalvey, new south wales, also yielded citromycetin (1), citromycin (2), and the new dihydro analogue ... | 2007 | 17958395 |
| rugulotrosins a and b: two new antibacterial metabolites from an australian isolate of a penicillium sp. | two new antibacterial agents, rugulotrosin a (1) and b (2), were obtained from cultures of a penicillium sp. isolated from soil samples acquired near sussex inlet, new south wales, australia. rugulotrosin a (1) is a chiral symmetric dimer, and its relative stereostructure was determined by spectroscopic and x-ray crystallographic analysis. rugulotrosin b (2) is a chiral asymmetric dimer isomeric with 1. its structure was determined by spectroscopic analysis with comparison to the co-metabolite 1 ... | 2004 | 15104517 |
