In an effort to identify the chemical constituents of fruiting bodies of Fomitopsis pinicola, a new lanostane triterpene glycoside, designated as fomitoside K, has been isolated from its methanolic extract. Its chemical structure was assigned on the basis of various spectroscopic studies.

Our phytochemical investigation of the roots of led to the isolation of two new lanostane triterpenes, 3-acetylpolycarpol () and 15-acetylpolycarpol (), as well as 15 known compounds (-). The structures of the isolated compounds were elucidated by an analysis of spectroscopic data. Compounds - were tested against nonsmall cell lung cancer cells (A549) and human cervical carcinoma cells (HeLa) using an MTT assay.

One of the most investigated molecular targets for anticancer therapy is the proto-oncogene , which is amplified and thus overexpressed in many types of cancer. Due to its structural characteristics, developing inhibitors for the target has proven to be challenging. In this study, the anti-MYC potential of lanostane-type triterpenes was investigated for the first time, using computational approaches that involved ensemble docking, prediction of structural properties and pharmacokinetic parameters, molecular dynamics (MD), and binding energy calculation using the molecular mechanics-generalized born surface area (MM-GBSA) method.

Five new non-holostane di- and trisulfated triterpene pentaosides, conicospermiumosides A-1 (), A-2 (), A-3 (), A-1 (), and A-2 () were isolated from the Far Eastern sea cucumber Levin et Stepanov (Cucumariidae, Dendrochirotida). Twelve known glycosides found earlier in other species were also obtained and identified. The structures of new compounds were established on the basis of extensive analysis of the 1D and 2D NMR spectra, as well as by the HR-ESI-MS data.
