Structure of herbarin.

چکیده
Herbarin (I) and dehydroherbarin (II) isolated from the fungus Torula herbarum (Pers.)1} possess weak antimicrobial activity and belong to the class of pigments in which a naphthaquinone moiety is fused to an oxacyclohexene ring at the 1,2-positions. The first compounds characterized in this class were javanicin (III) and fusarubin (also called oxyjavanicin) (IV) from the fungus Fusarium javanicutn2*3'^. Javanicin does not possess a tricyclic structure, but its biogenetic relationship to the tricyclic congener, fusarubin, is evident. Subsequently, Schmid and co-workers isolated CHO 0 CH3? 2

New naphthoquinone derivatives from the ascomycete IBWF79B-90A.
Bioactivity-guided fractionation of extracts from the fungus IBWF79B-90A resulted in the isolation of three known naphthoquinones, herbarin, dehydroherbarin, and O-methylherbarin and the azaanthraquinone scorpinone as well as three structurally related derivatives, O-phenethylherbarin and herbaridines A and B. All seven compounds exhibited cytotoxic activities against several cell lines.

In an attempt to explore the biosynthetic potential of the endolichenic fungus Corynespora sp. BA-10763, its metabolite profiles under several culture conditions were investigated. When cultured in potato dextrose agar, it produced three new heptaketides, 9-O-methylscytalol A (1), 7-desmethylherbarin (2), and 8-hydroxyherbarin (3), together with biogenetically related metabolites scytalol A (4)...

متن کاملA critical review on structure-soil-structure interaction
The purpose of this paper is to review computational methods in structure-soil-structure interaction. As a result of globalization, buildings are located close to each other. This issue happens especially in big cities, making the study of structure-soil-structure interaction as an essential part of structural design process. The effect of soil medium, on which the building structure stands, es...
متن کاملModified Structure Function Model Based on Coherent Structures
In the present study, a modified Structure Function was introduced. In this modified Structure Function model, the coefficient of model was computed dynamically base on the coherent structure in the flow field. The ability of this Modified Structure Function was investigated for complex flow over a square cylinder in free stream and a low aspect ratio cylinder confined in a channel. The Results...
