Abstract

Investigation of the solid culture of Ganoderma shandongense led to the isolation of 15 compounds, including one new steroid (compound 1) and fourteen known ones (compounds 2–15). Their structures were determined via extensive the nuclear magnetic resonance (NMR) spectroscopic analyses and quantum chemical calculations. Compounds 3, 9, and 14 exhibited inhibitory activities against acetylcholinesterase (AChE), with half maximal inhibitory concentration (IC₅₀) values of 29.4, 29.4 and 33.2 µM, respectively. Furthermore, molecular docking studies were undertaken to elucidate the interaction mechanisms between the compounds and the amino acid residues of AChE.

期刊介绍： STEROIDS is an international research journal devoted to studies on all chemical and biological aspects of steroidal moieties. The journal focuses on both experimental and theoretical studies on the biology, chemistry, biosynthesis, metabolism, molecular biology, physiology and pharmacology of steroids and other molecules that target or regulate steroid receptors. Manuscripts presenting clinical research related to steroids, steroid drug development, comparative endocrinology of steroid hormones, investigations on the mechanism of steroid action and steroid chemistry are all appropriate for submission for peer review. STEROIDS publishes both original research and timely reviews. For details concerning the preparation of manuscripts see Instructions to Authors, which is published in each issue of the journal.
