A facile route to perylenequinone

Tetrahedron Letters, 1988
Abstract Two-stage Ullmann and phenol coupling were effected in a singleoperation on methyl 5-bromo-1,2-dihydroxy-6,8-dimethoxynaphthalene-3-acetate to give dimethyl 5,8-dihydroxy-1,3,10,12-tetramethoxy-4,9-perylenequinone-6,7-diacetatewith ferric chloride as oxidant.

Anti-inflammatory perylenequinones from the endolichenic fungus Phialocephala fortinii triggered by a histone deacetylase inhibitor.

Fitoterapia
Inclusion of the histone deacetylase (HDAC) inhibitor suberoylanilide hydroxamic acid (SAHA) into the culture medium of the endolichenic fungus Phialocephala fortinii resulted in the separation of three new perylenequinones phialocephalarins E-G (1-3 ...

New Perylenequinones fromShiraia bambusicola

Planta Medica, 1991
Two new perylenequinones, named hypocrellin B and C, together with the known hypocrellin A were isolated from the stromatal tissues of Shiraia bambusicola. The structures of these compounds, including the absolute stereochemistry, were determined.

A new perylenequinone from a halotolerant fungus, Alternaria sp. M6

Chinese Journal of Natural Medicines, 2012
To study the metabolites of a halotolerant fungus Alternaria sp. M6.The metabolites were isolated and purified by various chromatographic techniques. Their structures were determined on the basis of physical properties and spectroscopic data.Nine compounds were isolated and identified as 8β-chloro-3, 6aα, 7β, 9β, 10-pentahydroxy-9, 8, 7, 6a ...
