A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 497-23-4, Name is Furan-2(5H)-one, molecular formula is C4H4O2. In an article, author is Dong, Mei-Yue,once mentioned of 497-23-4, COA of Formula: C4H4O2.
Benzofuran derivatives with nerve growth factor-potentiating activity fromPhellinus ribis
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 ofPhellinus 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 mu M.
