Core structure in roselipins essential for eliciting inhibitory activity against diacylglycerol acyltransferase.
Fungal roselipins, discovered as inhibitors of diacylglycerol acyltransferase (DGAT), consist of three parts; highly methylated C20 fatty acid, mannose and arabinitol. Demannosyl and/or dearabinitoyl roselipins were prepared chemically or enzymatically. Demannnosyl roselipins conserved the DGAT inhibitory activity, but the others lost the activity, indicating that the arabinitoyl fatty acid core is essential for eliciting the activity.

Funicone-related compounds, potentiators of antifungal miconazole activity, produced by Talaromycesflavus FKI-0076.
Talaromyces flavus FKI-0076, a soil isolate, was found to produce compounds which reinforce the anti-Candida albicans activity of miconazole. Four structurally related compounds, a novel one, designated actofunicone, and the knowns deoxyfunicone, vermistatin and NG-012, were isolated from the culture broth by solvent extraction, ODS column chromatography and HPLC. The structure of actofunicone was elucidated as benzoic acid, 3,5-dimethoxy-2-[[4-oxo-6-(2-acetyloxy propyl)-4H-pyran-3-yl]carbonyl]-, methyl ester by various spectroscopic analyses including NMR experiments. These compounds potentiated the anti-C. albicans activity of miconazole, decreasing the IC50 value of miconazole from 19 microM to 1.6 approximately 3.7 microM in the presence of the funicones.
