چکیده

Two novel cyclic hexapeptides containing both anthranilic acid and dehydroamino acid units, sclerotides A (1) and B (2), were isolated from the marine-derived halotolerant Aspergillus sclerotiorum PT06-1 in a nutrient-limited hypersaline medium. Both 1 and 2 are photointerconvertible and could be interconverted via a radical reaction initiated by direct photoisomerization. Both compounds showed moderate antifungal activity. Compound 2 also showed weak cytotoxicity and antibacterial activity.

JBIR-15, a new aspochracin derivative, isolated from a sponge-derived fungus, Aspergillus sclerotiorum Huber Sp080903f04.

In the course of our chemical screening program for novel metabolites by LC-MS monitoring, we isolated a new aspochracin derivative, JBIR-15 (1), together with aspochracin, from the culture broth of a sponge-derived fungus, Aspergillus sclerotiorum Huber Sp080903f04. The structure of 1 was determined to be N-demethyl aspochracin at the alanyl residue on the basis of extensive NMR and MS analyses.
