Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 3188-00-9, Name is 2-Methyltetrahydrofuran-3-one, molecular formula is C5H8O2, belongs to tetrahydrofurans compound. In a document, author is Lee, Seulah, introduce the new discover, Formula: C5H8O2.
Calvatianone, a Sterol Possessing a 6/5/6/5-Fused Ring System with a Contracted Tetrahydrofuran B-Ring, from the Fruiting Bodies of Calvatia nipponica
Calvatia nipponica is an extremely rare mushroom with a limited number of studies on its chemical components and biological activities published. Here we report the isolation of a novel sterol, calvatianone (1), possessing a 6/5/6/5-fused ring system with a contracted tetrahydrofuran B-ring, and four known steroids (2-5) from the fruiting bodies of C. nipponica. The structure of calvatianone including its absolute configuration was determined by NMR spectroscopic analyses, HR-ESIMS, gauge-including atomic orbital NMR chemical shift calculations, and ECD calculations. Ergosterol peroxide (3) and cyathisterol (4) suppressed the cell viability increase induced by 17 beta-estradiol in MCF-7 breast cancer cell lines, suggesting a possible approach for these compounds to serve as ER alpha antagonists.
