From the hydrophilic extract of the ascidian Polycarpa aurata three new compounds, N-(4-methoxybenzoyl)-N'-methylguanidine (1), butyl 2-(4-methoxyphenyl)-2-oxoacetate (2), and 2-(4-methoxyphenyl)-N-methyl-2-oxoacetamide (3), together with the known compounds methyl 2-(4-methoxyphenyl)-2-oxoacetate (4) and 4-methoxybenzoic acid were isolated. The structures of all isolates were determined

Aryl-alcohol oxidase (AAO) is a FAD-containing enzyme in the GMC (glucose-methanol-choline oxidase) family of oxidoreductases. AAO participates in fungal degradation of lignin, a process of high ecological and biotechnological relevance, by providing the hydrogen peroxide required by ligninolytic peroxidases. In
