| 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 |
| calbistrin e and two other new metabolites from an australian isolate of penicillium striatisporum. | an australian isolate of penicillium striatisporum collected near shalvey, new south wales, exhibited selective antifungal activity against candida albicans versus saccharomyces cerevisiae. bioassay-directed fractionation yielded members of the rare class of fungal metabolites known as the calbistrins. these included a new example of this structure class, calbistrin e (1), as well as the known polyenes calbistrin c (2) and deformylcalbistrin a (3). also recovered from p. striatisporum were new t ... | 2005 | 15844954 |
