| nail infection by aspergillus ochraceopetaliformis. | aspergillus ochraceopetaliformis is a rare fungal species that has not yet been identified as a proven human pathogen. here we report a case of a toenail infection in a healthy woman caused by this fungus. species identification was performed by scrutinizing the phenotypic and genetic characteristics of distinct isolates obtained at different times during the course of the infection. treatment with terbinafine plus ciclopiroxolamine was effective. | 2009 | 19274598 |
| antiviral merosesquiterpenoids produced by the antarctic fungus aspergillus ochraceopetaliformis scsio 05702. | five new highly oxygenated α-pyrone merosesquiterpenoids, ochraceopones a-e (1-5), together with one new double bond isomer of asteltoxin, isoasteltoxin (6), and two known asteltoxin derivatives, asteltoxin (7) and asteltoxin b (8), were isolated from an antarctic soil-derived fungus, aspergillus ochraceopetaliformis scsio 05702. their structures were determined through extensive spectroscopic analysis, cd spectra, quantum mechanical calculations, and x-ray single-crystal diffraction. ochraceopo ... | 2016 | 26697718 |
| trienic α-pyrone and ochratoxin derivatives from a sponge-derived fungus aspergillus ochraceopetaliformis. | a new trienic α-pyrone derivative asteltoxin g (1) bearing a tetrahydrofuran ring and a new ochratoxin derivative named ochratoxin a1 (5), along with seven known compounds, were isolated from a sponge-derived fungus aspergillus ochraceopetaliformis. the compounds (1-9) were evaluated on the basis of spectroscopic analyses and comparison with those of the reported data. the new compound ochratoxin a1 (5) exhibited anti-inflammatory activity against il-6 and tnf-α expression of the lps-induced thp ... | 2017 | 29130337 |
| ochracenes a-i, humulane-derived sesquiterpenoids from the antarctic fungus aspergillus ochraceopetaliformis. | nine new humulane-derived sesquiterpenoids, ochracenes a-i (1-9), were isolated from the antarctic fungus aspergillus ochraceopetaliformis scsio 05702. their structures including absolute configurations were elucidated on the basis of spectroscopic analysis, mosher's method, and electronic circular dichroism analysis. compared with previous humulane-type sesquiterpenoids, ochracenes a-i (1-9) featured novel carbon skeletons with corresponding methyl migration, ring cleavage, and carbon loss. two ... | 2017 | 28598633 |
