Abstract
Nine previously undescribed azulenoid-type sesquiterpenoids, including four common (1-4), four 5/6-cleaved (5-8), and one rearranged (9), were isolated from the edible-medicinal fungi Irpex lacteus. The structures of the compounds were established by combining spectroscopic methods, including integrated NMR, MS, and UV, as well as quantum 13C NMR and ECD calculations. All compounds exhibited a meaningful reduction in triglycerides activity. Notably, compounds 3, 5, and 6 displayed significant hypolipidemic activity, with EC50 values of 43.8, 37.9, and 39.7 μmol/L, respectively. These values are comparable to the positive control, lovastatin, which exhibited an EC50 of 37.6 μmol/L.

Abstract
The increasing prevalence of autoimmune diseases globally has prompted extensive research and the development of immunosuppressants. Currently, immunosuppressive drugs such as cyclosporine, rapamycin, and tacrolimus have been utilized in clinical practice. However, long-term use of these drugs may lead to a series of adverse effects. Therefore, there is an urgent need to explore novel drug candidates for treating autoimmune diseases. This review aims to find potential candidate molecules for natural immunosuppressive compounds derived from plants, animals, and fungi over the past decade. These compounds include terpenoids, alkaloids, phenolic compounds, flavonoids, and others. Among them, compounds 49, 151, 173, 200, 204, and 247 have excellent activity; their IC50 were less than 1 μM. A total of 109 compounds have good immunosuppressive activity, with IC50 ranging from 1 to 10 μM. These active compounds have high medicinal potential. The names, sources, structures, immunosuppressive activity, and the structure-activity relationship were summarized and analyzed.

Enhanced delignification and production of bioactive compounds in wheat straw by optimizing sterilization methods for Irpex lacteus fermentation. Food Chem 2024; 435:137570. [PMID: 37774616 DOI: 10.1016/j.foodchem.2023.137570] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 09/04/2023] [Accepted: 09/21/2023] [Indexed: 10/01/2023]
Abstract
This study aimed to examine the effects of sterilization methods on the degradation ability and bioactive compound production of Irpex lacteus in wheat straw. Following 28 days of fermentation, the lignin content of samples autoclaved and pasteurized at pH 4.5 was reduced by 16.0 % - 21.7 % compared to pasteurized samples without pH adjustment, accompanied by a significant increase in sugar yield ranging from 83.30 % - 96.35 %. Autoclaved samples exhibited the lowest total phenol content and antioxidant activity (P < 0.05). Bacillus occupied an absolute advantage (89.1 %) in samples pasteurized at pH 4.5, whereas 10 bacterial genera exhibited abundances above 1 % in pasteurized samples without pH adjustment. Furthermore, 45.1 % - 47.2 % of the metabolites comprised lipids and lipid-like molecules, and some of them were improved by pasteurization at pH 4.5. Overall, pasteurization at acidic conditions is an effective sterilization method for the fungal conversion of wheat straw.

Abstract
Four previously undescribed chamigrane sesquiterpenes, namely steccherins A-D, have been isolated from the fungus Steccherinum ochraceum. Their structures were elucidated by extensive spectroscopic analysis, as well as computational methods and single crystal X-ray diffraction. Steccherins A and B possess previously undescribed backbones which might be derived from normal chamigrane sesquiterpenes, especially that steccherin A possesses a spiro[5.6]dodecane carbon skeleton via a ring-rearrangement. Steccherins A, C, and D showed immunosuppressive activity with IC50 values ranging from 6.2 to 37.8 μM. The data suggested that these chamigrane sesquiterpenes have potential selective inhibition on LPS-induced B lymphocyte proliferation.

Cordycepin production by a novel endophytic fungus Irpex lacteus CHG05 isolated from Cordyceps hawkesii Gray. Folia Microbiol (Praha) 2022; 67:851-860. [PMID: 35678982 DOI: 10.1007/s12223-022-00981-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2021] [Accepted: 05/18/2022] [Indexed: 11/04/2022]
Abstract
Cordycepin is an essential nucleoside antibiotic with a broad spectrum of physiological functions, which is currently produced by the fermentation of Cordyceps militaris. Even though numerous efforts were made to enhance cordycepin production, the cordycepin yield is still limited. High-cordycepin-yielding strains are still a prerequisite for industrial cordycepin production in large amounts. Screening high-cordycepin-yielding strains from other sources may break new grounds for cordycepin. In this study, Cordyceps hawkesii Gray, with high homology to C. militaris, was selected as the source to screen the cordycepin manufacturing endophytic fungi. Four isolates capable of cordycepin production were successfully obtained among all isolated endophytic fungi. One of the four with better cordycepin yield was identified as Irpex lacteus CHG05, which belongs to the Phlebia species. The response surface methodology was applied to optimize the culture conditions for cordycepin fermentation. 162.05 mg/L of cordycepin with a 53.1% improvement was achieved compared to the original conditions. This study indicates that the endophytic fungi from C. hawkesii Gray could produce cordycepin and served as the first report for cordycepin by the white-rot fungus of I. lacteus. Even though the yield is low compared to C. militaris, this strain provided another choice for enhanced cordycepin in the future.

Abstract
Epigenetic modifiers are proved to be effective specialized products-mining tools by rationally regulating the gene expression of fungal biosynthetic pathways. Chemical investigation on the histone deacetylase inhibitor (HDI) vorinostat (also known as SAHA)-modified cultures of the basidiomycete Cyathus stercoreus (Schwein.) De Toni (Nidulariaceae) led to the isolation of nine previously undescribed sesquiterpenes, and four previously described ones. The structures of the nine undescribed compounds were determined by extensive NMR spectroscopic analysis, HRESIMS analysis, as well as ECD and NMR calculations. Notably, the isolated sesquiterpenes are exclusive or overproduced from the epigenetic modified cultures compared to the negative control cultures. Additionally, the skeleton types of the isolated sesquiterpenes include protoilludalane, illudalane, 1,11-seco-protoilludalane, 10,11-seco-illudalane, and 14(11→10)abeo-illudalane. It is noteworthy that the 14(11→10)abeo-illudalane skeleton is reported for the first time. Cystercorodiol A, 4-O-acetylcybrodol, cystercorotone, and cybrodol showed weak inhibitory activity against the bacterium Escherichia coli ATCC25922 with the inhibitory rates 34.7%, 33.0%, 32.3%, and 29.6% at the concentration 200 μM, respectively. This study suggested that epigenetic modifiers are also an effective tool for specialized metabolite-mining in basidiomycetes.

Abstract
Nine undescribed compounds, including six tremulane-type sesquiterpenoids, irpexolaceus A-F, one phenolic bisabolane-type sesquiterpenoid, irpexolaceus G, and two furan derivatives, irpexonjust A-B, as well as eight known analogs, were isolated from an endophytic fungus (Irpex lacteus OV38) of Orychophragmus violaceus (L.) O.E. Schulz, a Chinese medicinal and edible plant. The structures of these natural compounds were elucidated based on NMR, HRESIMS, single-crystal X-ray diffraction, and ECD spectroscopic data. Among the tested isolates (50 μg/mL), the inhibitory effects of irpexolaceus A, C, D, F, and G, irpexonjust B, and irpexlacte B against NO release from LPS-induced RAW 264.7 cells were higher than 45%, while irpexlacte C (42.6%), irpexolaceus B (39.6%), irpexonjust A (43.7%), and irpexolaceus E (33.6%) exhibited weaker inhibitory effects on the release of NO.

Abstract
Fungi are widely distributed in the terrestrial environment, freshwater, and marine habitat. Only approximately 100,000 of these have been classified although there are about 5.1 million characteristic fungi all over the world. These eukaryotic microbes produce specialized metabolites and participate in a variety of ecological functions, such as quorum detection, chemical defense, allelopathy, and maintenance of symbiosis. Fungi therefore remain an important resource for the screening and discovery of biologically active natural products. Sesquiterpenoids are arguably the richest natural products from plants and micro-organisms. The rearrangement of the 15 high-ductility carbons gave rise to a large number of different skeletons. At the same time, abundant structural variations lead to a diversification of biological activity. This review examines the isolation, structural determination, bioactivities, and synthesis of sesquiterpenoids that were specially produced by fungi over the past five years (2015-2020).

Abstract
Seven highly oxidized steroids, taccachatrones A-G (1-7), together with four known taccalonolides (8-11), were characterized from the rhizomes of Tacca chantrieri. The structures of 1-7 were established on the basis of spectroscopic data analysis, while the absolute configurations were determined by single-crystal X-ray diffraction. Compounds 1-4 may be derived from taccalonolide derivatives by the degradation of three carbon atoms. Compounds 7, 8, 10, and 11 exhibited cytotoxicity to human cancer cell lines, indicating that the presence of a lactone moiety, as well as a double bond between C-22 and C-23, might play key roles in mediating their cytotoxicity.

[PMID: 34177873 PMCID: PMC8226235 DOI: 10.3389/fmicb.2021.688202] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Accepted: 05/06/2021] [Indexed: 11/13/2022] Open
Abstract
The fungal strains Pseudogymnoascus are a kind of psychrophilic pathogenic fungi that are ubiquitously distributed in Antarctica, while the studies of their secondary metabolites are infrequent. Systematic research of the metabolites of the fungus Pseudogymnoascus sp. HSX2#-11 led to the isolation of six new tremulane sesquiterpenoids pseudotremulanes A-F (1-6), combined with one known analog 11,12-epoxy-12β-hydroxy-1-tremulen-5-one (7), and five known steroids (8-12). The absolute configurations of the new compounds (1-6) were elucidated by their ECD spectra and ECD calculations. Compounds 1-7 were proved to be isomeride structures with the same chemical formula. Compounds 1/2, 3/4, 1/4, and 2/3 were identified as four pairs of epimerides at the locations of C-3, C-3, C-9, and C-9, respectively. Compounds 8 and 9 exhibited cytotoxic activities against human breast cancer (MDA-MB-231), colorectal cancer (HCT116), and hepatoma (HepG2) cell lines. Compounds 9 and 10 also showed antibacterial activities against marine fouling bacteria Aeromonas salmonicida. This is the first time to find terpenoids and steroids in the fungal genus Pseudogymnoascus.

Abstract
Conosiligins A-D (1-4), four ring-rearranged sesquiterpenoids, were isolated from cultures of the basidiomycete Conocybe siliginea. Their structures and absolute configurations were determined by detailed spectroscopic analyses and equivalent circulating density (ECD) calculations. Compounds 1 and 2 possess a 5/8-fused ring system, while 3 has a 5/6-fused backbone conjugated with a γ-lactone. Compound 4 is a 5,6-seco tremulane derivative with the loss of a skeletal carbon, featuring a tetracyclic system involving a pyranone moiety. Compounds 3 and 4 inhibited Con A-induced T cell proliferation with IC50 values of 12.3 and 6.6 μM, respectively.
