Wu, Xuewei published the artcileTwo new 2-arylbenzofuran derivatives from the leaves of Morus alba, Safety of 5-(6-Hydroxybenzofuran-2-yl)benzene-1,3-diol, the publication is Natural Product Research (2019), 33(2), 204-211, database is CAplus and MEDLINE.
Two new 2-arylbenzofuran derivatives, moracinfurol A and B (1-2), and 10 known compounds (3-12) were isolated from the leaves of M. alba. Their structures were determined on the basis of spectroscopic anal. including 1D and 2D NMR and HR-ESI-MS. All of the 2-arylbenzofuran derivatives were evaluated for cytotoxicity against A549 cells with compounds 2, 4, 6-8, and 12 exhibiting moderate activity. Some cytotoxic 2-arylbenzofuran derivatives might induce autophagy characterized by the accumulation of LC-3 II.
Natural Product Research published new progress about 56317-21-6. 56317-21-6 belongs to benzofurans, auxiliary class Metabolic Enzyme,PDE,Natural product, name is 5-(6-Hydroxybenzofuran-2-yl)benzene-1,3-diol, and the molecular formula is C8H8O3, Safety of 5-(6-Hydroxybenzofuran-2-yl)benzene-1,3-diol.
