Three new benzofuran derivatives, namely ribisin E (1) ribisin F (2) along with ribisin G (3) were isolated from the MeOH extract of the fruiting bodies of Phellinus ribis. Their structures were elucidated based on the NMR analysis. Furthermore, the absolute configuration of ribisin E (1) and ribisin G (3) were deduced by the CD calculations, and the absolute configuration of ribisin F (2) was determined by comparing its CD spectrum and specific rotation with the data of known analogues. All compounds (1-3) exhibited the activity of promoting neurite outgrowth in nerve growth factor (NGF)-ediated PC 12 cell at concentrations ranging from 1 to 30 μM.

UI MeSH Term Description Entries
D000084682 Phellinus A genus of fungi in the family Hymenochaetaceae, class Hymenochaetales and phylum BASIDIOMYCOTA. Phellinus fungi are basidiomycetes which form large shelf-shaped mushrooms. Phellinus linteus (now Tropicoporus linteus) is a medicinal mushroom which produces compounds such as hispidin, a phenolic compound with antioxidant properties.
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D001572 Benzofurans Compounds that contain a BENZENE ring fused to a furan ring. Coumarones,Diphenylbenzofuran
D016501 Neurites In tissue culture, hairlike projections of neurons stimulated by growth factors and other molecules. These projections may go on to form a branched tree of dendrites or a single axon or they may be reabsorbed at a later stage of development. "Neurite" may refer to any filamentous or pointed outgrowth of an embryonal or tissue-culture neural cell. Neurite
D016716 PC12 Cells A CELL LINE derived from a PHEOCHROMOCYTOMA of the rat ADRENAL MEDULLA. PC12 cells stop dividing and undergo terminal differentiation when treated with NERVE GROWTH FACTOR, making the line a useful model system for NERVE CELL differentiation.

D020932 Nerve Growth Factor NERVE GROWTH FACTOR is the first of a series of neurotrophic factors that were found to influence the growth and differentiation of sympathetic and sensory neurons. It is comprised of alpha, beta, and gamma subunits. The beta subunit is responsible for its growth stimulating activity.
