“…The wood-attacking fungus Peniophora sanguinea produced a number of pigments which were chemically investigated by Gripenberg. − The structures of peniophorin ( 127 ), xylerythrinin ( 128 ), peniophorinin ( 129 ), penioflavin ( 130 ), peniosanguin ( 131 ), peniosanguin methyl ether ( 132 ), xylerythrin ( 133 ), and 5- O -methylxylerythrin ( 134 ) from this fungus were confirmed by X-ray crystallographic analysis (Scheme ). 15 …”

p-Terphenyls are aromatic compounds consisting of a central benzene ring substituted with two phenyl groups, and they are mainly isolated from terrestrial and marine organisms. The central ring of p-Terphenyls is usually modified into more oxidized forms, e.g., para quinone and phenols. In some cases, additional ring systems were observed on the terphenyl-type core structure or between two benzene moieties. p-Terphenyls have been reported to have cytotoxic, antimicrobial, antioxidant and α-glucosidase inhibitory effects. In this review, we will mainly summarize the structural diversity and biological activity of naturally occurring p-Terphenyls referring to the research works published before.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
