Abstract
In our ongoing study of fungal bioactive natural products, 12 previously undescribed triquinane sesquiterpene glycosides, namely, antrodizonatins A-L (1-12), and four known compounds (13-16) have been obtained from the fermentation of the basidiomycete Antrodiella zonata. The structures were established unambiguously via extensive spectroscopic analysis and theoretical calculations of electronic circular dichroism spectra. This is the first report of triquinane sesquiterpene glycosides. Compounds 1, 5, and 12 displayed antibacterial activity against Staphylococcus aureus with MIC50 values of 35, 34, and 69 μM, respectively.

Abstract
Eight new sesquiterpenes, namely, albocinnamins A-H (1-8), along with two known ones (9 and 10), have been isolated from the fungus Antrodiella albocinnamomea. Compound 1 possesses a new backbone that might be derived from cadinane-type sesquiterpene. Structures of the new compounds were elucidated by detailed spectroscopic data analysis, single-crystal X-ray diffraction, and ECD calculations. Compounds 1a and 1b showed cytotoxicity against SW480 and MCF-7 cells, with IC50 values ranging from 19.3 to 33.3 μM, while compound 2 displayed cytotoxicity against the HL-60 cell with an IC50 value of 12.3 μM. In addition, compounds 5 and 6 exhibited antibacterial activity against Staphylococcus aureus with MIC values of 64 and 64 µg/mL, respectively.

Abstract
Basidiomycetes produce a wide variety of sesquiterpenoids, which attract significant interest in pharmaceutical and industrial applications. Structural diversification of sesquiterpenoids is performed by sesquiterpene synthases (STSs), which produce a wide array of backbone structures; therefore, functional characterization and increased biocatalyst collection of STSs are important for expanding scientific knowledge and meeting the needs of advanced biotechnology. Gene identification and functional annotation of STSs from the basidiomycetous fungi Agaricus bisporus, Auriscalpium vulgare, Lepista nuda, Pleurotus ostreatus and Trametes versicolor were conducted. Through these investigations, the catalytic functions of 30 STSs were revealed using recombinant enzymes heterologously expressed in Saccharomyces cerevisiae. Furthermore, the unique function of an STS from P. ostreatus, PoSTS-06, was revealed to be the production of a novel sesquiterpene hydrocarbon that we named pleostene. The absolute structure of pleostene was determined by NMR spectroscopy and X-ray crystallography using the crystalline sponge method.

Abstract
Eight undescribed lanostane triterpenoids, physivitrins A-H, along with four known analogues, were isolated from cultures of the fungus Physisporinus vitreus. Their structures were elucidated on the basis of extensive spectroscopic methods, in which the absolute configuration of physivitrin A was elucidated using electronic circular dichroism calculation and nuclear magnetic resonance (NMR) calculation with DP4+ analysis. Physivitrins B and C showed inhibitory activities against nitric oxide (NO) production in LPS-activated RAW264.7 macrophages with IC50 values of 7.5 and 23.5 μM, respectively. Meanwhile, proinflammatory cytokines (TNF-α, iNOS and IL-1β) mRNA expression was also inhibited by physivitrin B significantly.

Abstract
Four new eremophilane-type sesquiterpenes, boeremialanes A–D (1–4) were obtained from solid substrate cultures of Boeremia exigua (Didymellaceae), an endophytic fungus isolated from Fritillaria hupehensis (Liliaceae). Boeremialanes A–C (1–3) are highly oxygenated eremophilanes with a benzoate unit attached at the C-13 position and are rarely found in nature. Their structures and absolute configurations were determined by extensive spectroscopic methods, electronic circular dichroism (ECD), and nuclear magnetic resonance (NMR) calculations with DP4+ analysis. Boeremialane D (4) potently inhibited nitric oxide production in lipopolysaccharide-treated RAW264.7 macrophages with an IC50 of 8.62 μM and was more potent than the positive control, pyrrolidinedithiocarbamate (IC50 = 23.1 μM).
